Goodbye from RUVIVAL

Happy Holidays from RUVIVAL

Dear followers, the RUVIVAL project will be completed by the end of the year. Our funding by the Hamburg Open Online University will expire, so we will not create any new learning content. But don’t worry – our content will stay online! You can find all our learning content on the Hamburg Open Online University website.

We will also continue with the RUVIVAL Simulation Game and offer another round of the educational game in spring 2021. The registration and further information about the game can be found on this page.

Also in 2020 we could continue the success of the last years. After all, what began in 2016 with a small team had numerous results and effects. We would like to highlight our greatest successes in the following.

Happy Holidays from RUVIVAL

Highlights of RUVIVAL

  • Together with Master students, PhD students and researchers at the Hamburg University of Technology we developed 19 Toolboxes. Each toolbox represents a bundle of different learning materials containing knowledge and methods developing rural environments.
  • We have also provided a virtual classroom and published 6 Lectures by guest lecturers on various topics related to rural development and reviving the rural.
  • To increase the accessibility of our learning materials, we have translated our content into Spanish, French, Urdu and German. This has demonstrably led to the distribution of the materials in other countries.
  • We have founded our own publication series, which is available for download via Open Research at the Hamburg University of Technology. In the RUVIVAL Publication Series 6 volumes were published.
  • In 2020 the RUVIVAL Simulation Game was successfully held for the 6th time. In this game students and other interested people plan several eco-towns in a simulated world. So far, over 600 people took part in the game, mainly students from Hamburg University of Technology and ICAM France.
  • Our making-of series shows how the different parts of the project were created.
  • In 2019, we partnered with Global Water Dances (GWD) to portray and support dance performances at a global event. These highlight a local water issue and improve the audience’s understanding of the importance of water.
  • Throughout the years we have given presentations about the project and released various publications. These are summarised on our Press & Publications page.

We proudly look back on successful years of knowledge transfer for the revival of rural areas. We would like to thank all our project partners, but also our followers and learners. Let us not forget that change is possible.

RUVIVAL Publication Series Volume 6 is Out!

Sand Dams Toolbox

Volume 6 of the RUVIVAL Publication Series is out! As this is the last volume, there is only one literature review this time. This literature review gives you an overview on sand storage dams and most recent research on the topic. A sand storage dam is a type of groundwater dam, a rainwater harvesting technique consisting of both an impermeable structure built across sandy riverbeds in seasonal streams and a crest raised above the riverbed. These have the potential to increase the water storage capacity and the yield potential of seasonal sandy rivers by trapping coarse sediments coming from the upstream catchment area in the dam. The optimal performance of a sand storage dam depends strongly on the proper selection of a suitable siting place, a tailor-made spillway design, which minimises the risk of siltation and appropriate construction procedures. While water in sand storage dams is of good quality, this can be affected during abstraction, transportation or storage.

Learn more about Sand Dams in the RUVIVAL toolbox on this topic!

As with previous papers, this paper has also been reviewed by members of the RUVIVAL Community.

All our publications are available to download for free via the library of Hamburg University of Technology. The previous issues can be accessed here.

This was the participation of RUVIVAL at the University:Future Festival!

Last week, the RUVIVAL team had the opportunity to present itself with its own booth at the digital showcase of the University:Future Festival. A video, mission statement and logo were presented, and on Wednesday additional questions could be asked and answered in Space , an interactive space simulation in which laptops fly through space and users are supposed to interact with each other. During several talks various appealing projects were presented, for example the page netlogo, which provides programmable model environments for the simulation of natural and social phenomena.

All in all, the festival was an exciting opportunity to expand the network and to inform interested people even this year!

RUVIVAL with its own booth at the digital showcase of the University:Future Festival!

The RUVIVAL team is very happy to participate with its own booth at this year’s University:Future Festival. The event will take place from 6th to 8th of October online.

The festival is organised by the association Stifterverband, which is the only one that offers holistic consulting, networking and support in the fields of education, science and innovation. The association describes the festival as follows:

“The University:Future Festival is breaking new ground as the first digital festival on higher education in Germany: For three days, the University Forum on Digitisation will bring together teachers, students, university management and other stakeholders from universities, politics and society and create a virtual space for the exchange of ideas on digital higher education”.

The RUVIVAL team will be represented by Dr. Ruth Schaldach and Mascha Frey.

We hope you have a nice summer!

With Amazing Proposals RUVIVAL SimGame Fifth Edition was Successfully Completed

We did it one more time! The 5th edition of the RUVIVAL SimGame 2020 has successfully concluded on Tuesday 23th June. The hard work of all students during the two months yielded wonderful outcomes and exiting debates on Sustainable Development.

Despite the students’ different locations and the particular challenges this year’s edition faced, all eco-planners could work together for the same goal, thanks to the online SimGame communication system. All town meetings and our final conference were held in the form of an online video conference. This multimedia concept made it possible to develop two plans for two different sites with very diverse environments.

Over the course of two months, teams of students from the Hamburg University of Technology in Germany and ICAM in France worked hard on planning two new Eco-Towns in a simulated world. This round gathered 67 eco-planners among them 14 bachelor and 28 master students from TUHH and 25 students from ICAM. They were supported by external participants contributing to the game by playing the role of Eco-Town inhabitants.

This year’s task was to plan one ecological settlement in Wales and one in Ethiopia. Each development plan had to be based on solutions that endure an ecological balance between soil, water and energy while providing the needs of the inhabitants in terms of housing, income, food, transport and waste assimilation. The plan also includes the assessment and mitigation of the Eco-Town’s ecological footprint. For this purpose, different groups of students were formed and were responsible for certain aspects of the development plan, town affairs and communication.

This year the Media & RMC Group reported in our virtual newspaper about the town meetings and planning progress. They kept track of the planning discussions and stayed well informed on the future inhabitants’ needs and requirements. Just as in real life, the virtual Eco-Towns planning benefited from the intense exchange and interactions that took place.

Earth, the main character in our simulated world, was responsible for publishing all the important announcements and sometimes interesting news. Earth had an important management role, since, well… you know… Earth knows everything in the world. Earth coordinated and moderated communication with the outside world, as well as the Travel Agency, Newspaper and Conference Center.

The Simulation Game keeps growing and we are already looking forward to the learning, knowledge transfer and exchange that is to come for 2021. Stay tuned!

Making of RUVIVAL now in Urdu!

RUVIVAL Logo

Many people are involved in developing RUVIVAL learning materials. This is both a challenging and rewarding process. On the one hand, it requires thorough planning and elaborate coordination, but on the other, unique perspectives, linkages and expertise emerge from this exchange. We strongly feel that this is a story that needs to be told alongside the sustainable rural development content you see on our website as the finished product. This is why we are excited to announce: Making of RUVIVAL is now also available in Urdu!

Urdu Version: روائول کی تیاری

This article was first published in German on Insights.

This is the beginning of a series of Making of publications on the RUVIVAL simulation game. Every year, the participants have 7 weeks to plan eco-villages. 2020 makes this the fifth round. The aim of the series is not only to share our experiences and invite participation, but also to enable others to reproduce or adapt this simulation game according to their needs.

Currently, it is still possible to enter this year’s game. You can still take on the role of a fictitious person who intends to settle in the community later.

Registration for the RUVIVAL Simulation Game

The imagination can be given free rein and can be brought into the planning process.

Making Of Simulation Game Part 1 – The Locations

This first part deals with giving an overview of the concept. Furthermore, the objective of the game is explained: plan an ecological settlement with the mission to reduce the ecological footprint and increase biocapacity.

Making of Community Project

RUVIVAL Community

This article was at first published in German on Insights.

The Community Project is a partnership between RUVIVAL and Global Water Dances. Global Water Dances began in 2011, with the goal to use dance to raise awareness on water issues and to encourage the creation of solutions for water preservation and conservation through community engagement. Each year they organise a worldwide event to achieve this goal. In 2019, RUVIVAL decided partner with Global Water Dances to promote 8 sites and to report about them in more detail on the RUVIVAL website.

A call for scholarships for groups from Africa and India was part of this project. The goal was to increase participation in this global event from these countries and we reached this aim. On the 15th of June in 2019 RUVIVAL cooperated with 7 sites in Africa and one in India: Ganvie (Benin), Johannesburg (South Africa), Durban (South Africa), Bwaise and Beach House in Kampala (Uganda), Diani (Kenya), Kilifi (Kenya), and Motakondur (India). On June 15, 2019, each of these eight dance troupes partook in the Global Water Dances event, successfully raising awareness and encouraging their neighbors to action.

Afterwards, RUVIVAL’s work began. Our objective after the event was to publicise the hard work of each site. We collected photos, videos, music, and photo and video release forms from the sites. For each site we published a post. The process of creating these posts is discussed below.

Video Editing

Using raw footage of the event from each site leader, nine videos were made. One was an overview of all eight sites. (This can be found at our Community Project page.) The others were three minute videos, specific to each event. (These can be found at their respective posts: Johannesburg, Durban, Kilifi, Diani, Ganvie, Beach House, Bwaise, Motakondur.)

First, we analysed the footage that each of the sites sent and then used Final Cut Pro to edit them. While editing, we cut out the parts that were unusable. A section was unsuitable if it was not of sufficient quality or if an audience member was in the frame. (We did not get consent from the audience members to use their images in our videos.)

After this initial editing, some of the videos were already about three minutes long; so, further editing was not required. For those that were longer, we had another look and whittled the video down to its most interesting and important scenes until the video was three minutes long. Once the videos were the required length, we added the intros and outros, including credits.

Post Creation

We wanted each post to have some unity. Each post had at least a video (see above for more information), an event summary, photos, and a background on the dance group. Additional sections were added depending on the information gathered by our contact person from each sites.

Creating the summaries of the events took quite a bit of communication with the groups. We focused on collecting the following information:

  • the motivation of the artistic director and/or site leader in joining the Global Water Dances event,
  • the meaning behind the choreography,
  • and the water issues explored and ‘discussed’ at the event.

After the initial draft, the posts were reviewed by the respective contact person of each site, edited and finally approved for publication. This ensures that the message they were trying to convey was accurate and that no misunderstandings occurred.

All material was published at the end of 2019 and distributed through several social media channels in order to rise awareness on water issues.

RUVIVAL at the DAAD conference Virtual Exchange

RUVIVAL Logo

We were honoured to participate at the international conference ‘Virtual Exchange – Borderless Mobility between the European Higher Education Area and Regions beyond’ organised by German Academic Exchange Service (DAAD – Deutscher Akademischer Austauschdienst).

In the session ‘Building Up Expertise and Capacities’ Ruth Schaldach presented RUVIVAL as an e-learning project for sustainable development along with Durban University from South Africa. The focus of the conference was set on building up more cooperations with African Universities, especially in the field of cooperative online learning. The RUVIVAL Simulation Game is one example for a cooperative international learning experience.

Kilifi

Global Water Dances 2019

At Kilifi Creek, the Kilifi Dancers performed ‘Maji ni Uhai’ (Water is Life). The objective was to create awareness on how to save and utilise water.

Creative Commons LicenseKilifi Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Using a traditional Giriama song for music, the performance was a merger of traditional and modern dance. Choreographer, Mohamed Ismat, mixed these different styles into a stunning dance with a clear message: ‘Water is life; use it sustainably.’

The location of the performance is symbolic. Kilifi Creek is an important coastal water source, not only for the community of Kilifi, but also for the world at large. It flows into the Indian Ocean, connecting Kilifi to people around the world! The residents value the creek for the many resources and beauty it provides.

The creek is even more precious to the community as Kilifi is very drought-prone. Every drop of water is extremely important. In fact, the residents have organized a weekly beach clean-up, to protect their water. This performance is just another step in safeguarding their future.

The Kilifi Dancers is an interesting mix of volunteers, youth and community groups, and local dance groups. The troupe was formed specifically for this event.

Site leader, Mwanase Ahmed, partnered with local conservation initiatives, the local university, environmental clubs, the local international school, the local government and the Kilifi community to help raise awareness about these water issues.

 

 

Diani

Global Water Dances 2019

Students from the Peace Village Education Center performed ‘Maji, Maji’ on June 15 in Diani, Kenya. As a part of an awareness campaign, the performance highlighted the scarcity of fresh water in the area.

Creative Commons LicenseDiani Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

The performance was split into 4 parts:

  1. a call and response song, performed in Kiswahili,
  2. the Global Water dance,
  3. a local dance,
  4. and a participatory dance with the audience.

Peace Village Primary School is situated, specifically, in the Maweni neighborhood of Diani. Maweni experiences marginal and absolute poverty; many residents do not have running water in their homes. And, if there is running water, it is usually salinated. In this area, access to clean water and sanitation is limited, salinised, and often overpriced. The Soa song, used in the third part of the performance, was created to bring awareness to Maweni’s water issues. During the chorus the children shout ‘Maji, Maji’, which means ‘Water, water’ in Kiswahili.

Kate Bouchier was the site leader and choreographer for this event. She, also, represents Family Thing.

Family Thing uses dance as a vehicle to provide opportunities for empowerment, support and a sense of belonging to marginalised, stigmatised and/or vulnerable peoples.

The dancers are all students from the Peace Village Education centre. This centre is a small school in the Maweni area of Diani beach which works with children from predominently poor families in the surrounding areas.

Other Activities to Raise Awareness

The activities below were conducted prior to the dance in order to raise awareness of local water issues.

  • The students from Peace Village learned about the importance of clean water and sanitation.
  • Video interviews were conducted asking the school children and local members of the community what are in their opinion the most important water related issues.
  • Posters and flyers were created highlighting the importance of clean water and sanitation.
  • Talks were conducted about local sand harvesting, which is the process where sand is collected, or extracted from the local reefs.
  • Information was shared on local websites and Facebook pages, including Diani public groups.

 

Motakondur

Global Water Dances 2019

Students from Zilla Parishad High School in Motakondur, India performed on June 15. Organized by Divya Sree Madichati and choreographed by Sriman, the dance focused on the importance of potable water.

Creative Commons LicenseMotakondur Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

The major objective was to create awareness of the lack of clean drinking water and emphasise its importance. In Motakondur, the fluorine content in the water is 10-20 times higher than the amount permitted in WHO regulations; therefore, fluorosis is common.

Fluorosis affects the teeth and bones, especially in children under the age of nine.  Long term effects of the disease have lead to the death of many residents. Most of the residents were unaware of the consequences, and therefore, continued to drink this water. Now, after a new awareness campaign from the government, the residents began to search for water free of fluoride and impurities.

Most of the water in this area is fluoridated, and treatment to remove fluoride is expensive, if not impossible. Consequently, the villagers of Motakondur must travel long distances to find potable water for their families. Thus, those who do not have the means to travel must use this fluoridated water.

As educating the younger generation is key to preventing fluorosis, the GWD performance was held at the local high school. In order to collect non-fluoridated water, the staff has to walk more than 20 km to provide potable water for the school. The water is then stored in a tank, where students can access it.

Durban

Global Water Dances 2019

The KwaMashu School of Dance Theatre performed a five-part event in Durban. Choreographer and site leader, Vusi Makanya, focused on the droughts common to the area.

Creative Commons LicenseDurban Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

South Africa is a country located at the southern tip of Africa. It is home to 49 million people. As more and more people migrate into cities from rural villages, the pressure for Durban to meet water demand is ever increasing. Here, Umgeni is the primary source of water for over 3.5 million people. The residents are especially concerned about water shortages in and around the city.

The aim of the choreography was to remind us of the power of water as it moves through our lives. Split into five sections, each routine carried a specific message:

  1. Some people walk long distances to get water.
  2. Water is a vital source of life.
  3. Like cold water to a thirsty soul, so is good news from a distant land.
  4. Droughts are deadly.
  5. Fresh water is crucial for drinking.

This event raised awareness about the role water plays in social and economic development with the view of changing the attitudes and behaviours of the people.

Special thanks are given to the UMoyo Restaurant and the Parks, Recreation & Culture department of the eThekwini municipality.

 

 

Bwaise

Global Water Dances 2019

Dancers from the Kawempe Youth Center of Kampala, Uganda performed to underline the importance of clean drinking water. Site leader, Lennie Kleinen, focused on waterborne diseases, such as cholera and typhoid.

Creative Commons LicenseBwaise Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Bwaise is one of Kampala’s largest urban slums. The people of Bwaise face housing, drainage, water and sanitation issues daily. The area has severe flooding after heavy rains, causing outbreaks of cholera and typhoid. Bwaise residents have been relying on often polluted underground water streams for everyday domestic use. Up to today, Bwaise does not have a piped water system.

During the performance, the Kawempe Youth Center dancers used different styles of dance. They combined traditional dances with contemporary techniques. Wearing traditional dress, the performers carried clay water pots and jerrycans as a medium through which they could communicate their message. The event was held near a centrally-located, heavily polluted body of water, where every minute thousands of people pass by.

RUVIVAL partners with Global Water Dances

RUVIVAL and Global Water Dances worked together to support eight sites during the 2019 GWD event. Located in Asia and Africa, each site choreographed a performance to highlight a local water issue.

Today we updated our community page to include community projects concerned with rising awareness on pressing issues like water scarcity, pollution and other water related issues. For more information about this project, visit our new Community Project page with the first three posts for the sites in Johannesburg, Beach House, and Ganvié. Each Thursday in the next three weeks more project site videos will follow.

Ganvie

Global Water Dances 2019

Ganvie is situated on the surface of Lake Nokoué in the South of Benin. The dance group Missimidé de Ganvié performed Atchi (a site-specific dance) to send the message ‘Welcome to the Water’.

Creative Commons LicenseGanvié Video by RUVIVAL Team is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

In the eighteenth century, many Beninese fled the slave raids on the coast to Lake Nokoué. Here, they created a thriving village on the lake. Over time, the residents have formed a communion with the water.

But life is not perfect; the water in Lake Nokoué is saline. Therefore, the residents cannot drink its water. Wells have been drilled around the lake, but they are no longer productive. In order to live, they make long trips on boats to find fresh water and return loaded with containers of potable water. It is quite a paradox: to live on the water, but not have any to drink.

The performance is a play on these boat trips. The dance is an imitation of the daily routine most residents must make just to get clean drinking water.

Missimidé de Ganvié is local dance group, consisting of dancers and musicians. The choreographer, François Gnonlonfoun, is a native of the region. Using the knowledge and experience he has gained living on the lake, he created a powerful performance.

Future Plans

Ganvie is not the only part of the country with water issues. In the North, access to water is becoming more and more difficult. Groundwater tables have lowered, exasperating the problem. In coming years, SunRise Films and Ayéman Aymar Esse plan to organize their future GWD performances in this region of Dassa.

 

 

Beach House

Global Water Dances 2019

The Beach House event took place on the shores of Lake Victoria in Kampala, Uganda. Here, three local dance groups were joined by orators to motivate their community to combat water pollution.

Lake Victoria is one of the largest lakes in the world. It is also the major drinking water source for Uganda. However, water pollution is a major problem here. Contamination from single-use plastics is of particular importance to the Ugandans.

Site leader and choreographer, Jill Pribyl, organised an impressive event to raise awareness of this problem. Dancers from the Soul Ballet Studio, the Clay Dance Company and Break Dance Project Uganda came together to perform several dances on June 15. Guest speakers, Dr. Tindimugaya, Dr. Bhasdkar, Dr. Gidudu and Stefan Deconinck, spoke about the issues facing Lake Victoria and how to affect change.

Audience members were educated on the distribution of clean water in Uganda. Additionally, they were urged to pledge to reduce their use of single-use plastics.

Global Water Dances 2019

A local theatre company, Sketch Productions, performed Droogfontein to raise awareness about Johannesburg’s water-related problems.  Artistic Director, Hannah Nokwazi van Tonder, focuses on the issues related to water scarcity and lack of proper water treatment in the performance.

Droogfontein, or dry fountain in English, is a good play on words. A well working wordplay as many places in South Africa have ‘fontein’ in their name. The name is also a commentary on capitalism. There is no new land to call ‘fontein’, yet the capitalist owners continue to deplete these ‘fountains’ until they are dry, leaving little to none for the rest. We, as humans, can no longer find the sources of the springs of life that we so desperately need.

The performers are residents of a fictitious town, Droogfontein. They search for the true source of life, a fountain of water. But people are not perfect, and so the source is exploited and taken for granted. Will the community recognize the importance of protecting this precious water or is the name droogfontein a prophecy?

Hannah, along with her choreographers Quinton S. Manning and Joel Leonard, collaborated with a team of eight performers from the ages of 11 to 26 to help make this performance a site to behold. All come from the group, Sketch Productions.

A note from the Artistic Director

I remember the first drought I ever experienced. The water crisis was so bad that we had to wait every week for trucks to come into town and bring us water. But this was not free; we had to pay large sums for it. From that moment onwards, I made sure to speak out not only about water shortages, but also the human impacts of the water crisis. Even to this day, I experience issues. Where I live now, we always see water in the streets, smelling less like water and more like sewage. Additionally, we constantly have water shortages, leaving us without.

I was humbled to be a part of the Global Water Dances community. Staging Droogfontein, for me, was less about giving a performance and more about raising awareness about Johannesburg’s water problems. Many times we see the city as this all giving, all divine construct, when many times it fails to provide for our daily needs. [Hannah Nokwazi van Tonder]

Introduction to Greenhouses

RUVIVAL Overview

Greenhouses are built to protect plants from harsh climates and to provide warmth throughout the year. Additionally, they help to save water in water scarce regions.To get a sufficient yield of crops, the plants need a stable and a suitable climate. Generally, these conditions are not always given as most regions have to face weather extremes.

The following overview will give you information on greenhouses in general, their pros and cons and successful examples of greenhouses in rural regions around the world.

Fourth Round of RUVIVAL SimGame Completed Successfully

The RUVIVAL SimGame 2019 has successfully concluded on Tuesday 25 June, with the dazzling display of wonderful outcomes yielded from the hard work of students during the two months. Three virtual Eco-Towns were planned, 1 located in Wales and 2 in Ethiopia. Over one hundred students joined in the game as eco-planners – 68 from TUHH in Germany and 37 from ICAM in France supported by external participants contributing to the game by playing the role of Eco-Town inhabitants. They united for the same goal and worked without hindrance despite of the different locations thanks to the online SimGame system.

Tasks in the Eco-Town planning game

The fundamental task of the students was to plan the future Eco-Town and find ways to incorporate various water and energy solutions with sustainable agricultural practices, while taking into consideration the specific challenges resulted from different geographic, political, economical and climatic conditions, as well as the diverse opinions of the inhabitants. To accomplish the final task, the students have gone through several steps and formed into different groups responsible for the respective development plans and town affairs. Approximately 370 posts and 1300 comments were created during these processes which paved the way to the final achievements.

It would be unfair to leave the SimGame without mentioning those important management roles. First is our Earth, the main character in the virtual world, who is responsible for publishing all the important announcements and sometimes interesting news. Earth knows everything in the world and gives direction by answering their questions.

This year over 50 articles were published in our newspaper reporting about the town meetings and planning progress. Each article was also discussed in the comment section and all participants were not only up to date, but also well informed on new developments in the area of environmental practices and technologies.

Travelling to other parts of this fictional world was made possible by the Travel Agent, the smart robot who is responsible for the travel agency. Overall 22 travel tickets were issued to the participants, most of which led to Ethiopia and Arba Minch being the most popular towns. The currency in the game to get a ticket were written articles as we considered the spread of useful knowledge as most valuable.

Town meetings and a final conference were held in form of an online video conference so that it was possible for all participants to present and discuss the concepts not just in written form. This multimedia concept made it possible to develop three elaborate plans for three sites with very diverse environments.

RUVIVAL in 2020

As in the real life, the virtual world will keep growing and improving from the intense exchange and interactions. We are happy to announce that the next round is already planned for 2020! We are in negotiations to get more Universities, especially from Africa, involved and hope to find more future inhabitants from all over the world willing to share their knowledge. Stay tuned for the next round of SimGame!

Open Source Solar System

RUVIVAL DIY

Distributed, or decentralised energy systems can be build with Open Source Renewable Energy Hardware. Within the Hamburg Open Online University project Collective Open Source Hardware, short cos(h), step-by-step instructions were created to build your own open source solar system. The tutorial is based on Libre Solar components and offers a modular system that can be set up, depending on power and storage capacity requirements. Basic understanding of electrical engineering and programming is required for a successful construction.

Manufacturing of a Solar Charge Controller

A charge controller feeds electrical power from solar panels (or wind turbines or bicycle generators) in the battery storage system. If electricity should be stored in batteries, a charge controller is always required, as it prevents the battery from overloading or overcurrent. Cos(h) created a manual that shows how to manufacture a MPPT (Maximum Power Point Tracker) charge controller. It is a PCB (printed circuit board) for running an electrical solar power system.

Click here to open the cos(h) tutorial and build your own MPPT.

Aquaponic Farming using the Asian Clam

RUVIVAL_Click&Play

This Toolbox element was created in cooperation with high school students. Read more here

Aquaponic farming is a combination of aquaculture (in this case, growing Asian clams) and hydroponics (growing plants without soil). The main advantage of aquaponic farming is that the system is easy to operate as you only need to circulate the water, to feed the animals and to harvest the plants. The most obvious advantage is that two food sources can be grown in one system. In order to demonstrate the benefits of an aquaponic system, pupils of the Goethe Schule Harburg (School in Hamburg) built a small-scale model under supervision of their teacher Olaf Zeiske. It consisted of four compartments along with a pump and circulation system and they continually monitored the circulation of nutrients.

Here is the report from Felix Leuner and Emil Regelski on their version of an aquaponic system:

We ran the model for six months. During which, we observed that green algae caused many problems. Therefore, it must be monitored closely. Without proper maintenance, the algae would build-up in the tubes of the circulation system and, finally, clog them. To prevent this from happening, a screen could be placed at the inlets of the tubes or bigger tubes could be used.

Due to the fact that we built the system in direct sunlight, we lost much water due to evaporation. This was done with the intention of providing the algae with as much sunlight as possible. Our recommendation would be to construct an aquaponic farm in half-shade. By doing this, you can prevent the system from both overgrowth of algae and also too much evaporation.

A review: RUVIVAL at Bücherhallen Hamburg introducing the Simulation Game

Last weekend we offered a workshop at at the public libraries (Bücherhallen) in Hamburg. After the welcome and introduction by project manager Ruth Schaldach, Tina Carmesin presented the overall concept of RUVIVAL.

The main topic of the event was the RUVIVAL Simulation Game. Ruth Schaldach described the game design and showed the game platform. After this, the participants were asked to explain their vision of ecological towns and a discussion started. In the end the registration process for participating the game was shown.

Last week, the 2019 RUVIVAL Simulation Game officially started. We are more than happy that in this years edition we have already 125 participants registered in our system! The first planning tasks were executed and fruitful discussions evolved. Since 2017 students in Hamburg, Paris and Toulouse face the challenges to plan ecological towns in the simulated world created by the RUVIVAL Team. However, everyone can participate! If you want to take part in the game find further information and the registration form here.

We are looking forward to another exciting game. We hope to see you online!

Digital Changemaker group visits the TUHH

Hochschulforum digitalisierung

A couple of weeks ago we had a visit from the student group Digital Changemaker. They are part of the German Forum for Higher Education in the Digital Age (Hochschulforum Digitalisierung). This group is made up of 15 students from all over Germany, studying in different fields. They are working on improving digitalisation at the university level, looking at different aspects such as innovative and didactic learning formats, platform solutions, sustainability, e-participation, etc.

The students visited the Hamburg University of Technology (TUHH) to get to know different projects from the Hamburg Open Online University (HOOU). Carla Orozco Garcia from RUVIVAL showed them how we create Open Educational Resources (OERs) in form of stop motion videos. They visited her in the editing room, where she showed them our video-making process. This starts by creating a storyboard. Then, the video elements are drawn, printed and cut out. Afterwards the video is filmed at the studio and finally, it is all put together with a video editing software.

If you are interested in learning more about this process, take a look at our Making of RUVIVAL Stop Motion Videos section.

Conference on Permaculture, Sustainability and Water on La Gomera

Poster Conference on Permaculture, Sustainability and Water La Gomera

Ever since its beginning, RUVIVAL is on a mission to spread the word on sustainable rural development. We just visited the island of La Gomera to be part of a conference on permaculture, sustainability and water.

Local and international experts presented innovative ideas in the context of rural development, sustainability and water use. However, we also enjoyed taking the opportunity to network in workshops and engage in mutual exchange with likeminded people. We swapped seeds, got to know local projects and enjoyed regional products and music.

Specific topics were discussed in working groups, such as permaculture, reforestation, ecological cultivation practices, eco-tourism and water reuse. Thus, about 100 participants as well as representatives of the Island Council found common interests and connecting points to further develop the island of La Gomera in a sustainable manner. All in all it was a successful start for future cooperation and more events.

Geological Background for MAR Systems

RUVIVAL Overview

If you want to design a managed aquifer recharge (MAR) system, an understanding of the geological background at your site is necessary.

Aquifers consist of different rock and sedimentary layers. The type and characteristics of these layers determine whether and how much water can infiltrate. A high porosity and permeability is helpful for aquifer recharge, but not all layers have the wanted properties. Moreover, the geological history varies from region to region, therefore it is helpful to include a local geologist into the planning process of a MAR.

The following slides provide you with a basic geological understanding on rock types and their important properties: porosity and permeability. A quiz is included to let you check on your gained knowledge.

Facts and Misconceptions about SRI

RUVIVAL Quiz

SRI stands for System of Rice Intensification. Although not a new technique, many questions about SRI remain unresolved. Its proponents and critics still debate the proclaimed SRI benefits. By August 2018, more than 800 scientific papers on SRI have been published, discussing this concept. Below you will find some facts and misconceptions about SRI. Try to guess which ones are true and which not. You can always learn more about this topic in our Interactive Lecture on SRI.

New Making of RUVIVAL Section

Many people are involved in developing RUVIVAL learning materials. This is both a challenging and rewarding process. On the one hand, it requires thorough planning and elaborate coordination, but on the other, unique perspectives, linkages and expertise emerge from this exchange. We strongly feel that this is a story that needs to be told alongside the sustainable rural development content you see on our website as the finished product. This is why we are introducing a whole new Making of RUVIVAL section. Here you will be able to read more about how different RUVIVAL elements are created, about the technical and pedagogic aspects, as well as about the experiences of those taking part.

Making of RUVIVAL

Making of RUVIVAL

RUVIVAL Logo

Sustainable rural development is an answer to a multitude of complex pressing issues that require global attention. The responses to these issues are equally complex and the best ones are those that draw synergistic connections and offer holistic solutions. In the making of RUVIVAL, these complexities are recognised and addressed, both when it comes to problems and solutions. That is why in developing RUVIVAL learning elements, different tools, materials and styles are used, for a comprehensive learning experience. Some elements have a more technical or practical nature, while others are more theoretical. Some are text based and others are image based.

Collaboration is key for developing RUVIVAL into the open access e-learning platform it is today. You can see all RUVIVAL collaborators in the Team list.

In the following, you will learn how all these different components come together when creating RUVIVAL. Click on the elements to learn more:

Rural Energy Systems Literature Review

RUVIVAL Literature Review

Providing access to electricity in rural areas is a major challenge, especially in developing countries. Inefficient energy use and an unreliable energy supply with limited access not only has an adverse effect on economic productivity; more importantly, it also affects people’s quality of life and is having a strong impact on the environment at local (land degradation), regional (air, water and soil pollution) and global levels (climate change). This paper reviews distributed renewable energy systems and concentrates on energy services for electricity generation in Africa.

UPDATE: The updated version of this literature review is part of RUVIVAL Publication Series Volume 4. A working version of this paper was previously published and discussed online. It can be read here.

 

Rural Energy Systems

Rural Energy Systems Toolbox

Rural Energy Systems ToolboxUniversal access to modern energy is driven by both local and global factors, including climate change, population increase and future energy security. In order to be sustainable in the long term, rural energy systems need to meet the energy requirements of rural dwellers, while raising economic productivity and contributing to a sustainable development of the living conditions in these areas. They should also provide inputs for further rural energy interventions and reduce the environmental impact by focusing on renewable energy technologies.

Measuring Rainfall Frequency and Intensity

RUVIVAL Analysis

Ever wondered how much rain is falling at your place? Then you should learn more about measuring rainfall to estimate your rainwater harvesting potential with this e-learning tool.

Methods for Rainwater Quantification

We will provide you with a rain gauge construction manual. This gives you the opportunity to measure your rainfall without using much equipment. Everybody can help to keep an eye on our planets water resources and you can start. Have a look by yourself and try out your first tests.

Measuring Rainfall by Birthe Hohm and Ruth Schaldach is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Rainwater is an important water resource by naturally irrigating plants and recharging water sheds. Rainfall is collected by rainwater harvesting (also see: traditional and land-based rainwater harvesting), stored and later used. Thus, knowledge on the speed of recharge is important in order to know how fast you can use your stored water resources. Additionally, rainfall is changing with the seasons in frequency and intensity. You can calculate with this Rainwater Collection Calculator based on your data the yearly collection potentials, which helps to plan your storage devices. As dryer a region is as more important it is to collect and store in these seldom peak times, which makes an exact planing even more important. Consequently, observing the rainfall is one of the first steps for sustainable usage practices.

 

Water Condition Analysis Guide

RUVIVAL Analysis

Ever wondered how the water quality of your water resource is? Then you should learn more about the condition of your water sources with this e-learning tool.

Methods for Water Quality Determination

We will provide you with some techniques, which do not need much equipment. This gives you already an idea on your water body’s condition. Everybody can help to keep an eye on our planets water resources. However, for more precise measurements we need more elaborate methods. Have a look by yourself and try out your first tests.

Water Condition Analysis Guide by Birthe Hohm and Ruth Schaldach is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Water condition analysis is the first step to check on the quality of a water body. It describes the biological, chemical and physical state of water and tells you how healthy a water resource is. A good water quality and good water health is important for the ecosystem, thus checking on the water condition is an important step for sustainable water usage practices and once implemented to monitor these. However it is also very important for your personal health and well-being. It follows a simple logic: You can only stay healthy, if you use good quality water for drinking water supply and irrigation systems.

Agriculture and urbanisation draw heavy on the worlds water resources and unsustainable practices show more and more their signs. Already, several rivers and lakes are polluted and even groundwater resource are not protected from getting increasingly polluted any more. However, everybody is in the responsibility to avoid pollution and to treat your environment responsible. All water resources are part of the hydrosphere and thus connected with each other, which leads to an easy spread of pollution from one water resource to another. Due to this importance several methods for measuring water quality developed over time. For a precise determination of water quality, a complex set of measurements are needed like Measuring Groundwater QuantitiesMeasuring Surface Water Quantities and Measuring Rainfall Frequency and Intensity, but for a first idea only few parameters are sufficient.

 

World Soil Resources Literature Review

RUVIVAL Literature Review

During the last few decades, technological innovations, economic development and hyper-globalisation, have made significant changes to the fundamental structure of the Earth. This includes the soil, which is one of the most important substances for living creatures. FAO defines soil degradation as the decline in soil health condition, as a result of which the capacity of ecosystems to provide goods and services for its beneficiaries is diminished.

The total amount of arable land decreased, mainly due to unsuitable land usage related to agricultural practices. The Third Agricultural Revolution and growing food demands have put critical stress on agricultural land resulting in serious soil degradation. As a result of modern agricultural practices, both chemical and physical degradation of soil occur. An interrelated factor contributing to the loss of arable land is erosion, which is a naturally occurring process, which can be promoted by human activities.

This paper reviews research conducted on the global soil situation and goes deeper into regional soil conditions. Geographically specific causes for soil loss are also given. Soil management and monitoring systems are recommended, however, it should be noted that each system needs to be adapted to its specific environment.

UPDATE: The updated version of this literature review is part of RUVIVAL Publication Series Volume 5. A working version of this paper was previously published and discussed online. It can be read here.

 

Measuring Surface Water Quantities

RUVIVAL Analysis

Ever wondered how much surface water is in rivers, lakes, channels and reservoirs around you? Then you should learn more about measuring surface water with this e-learning tool.

Methods for Surface Water Quantification

We will provide you with some measuring techniques, which do not need much equipment. This gives you already a good idea on your surrounding surface water status. Everybody can help to keep an eye on our planets water resources. However, for more precise measurements you will need more elaborate methods. Have a look by yourself and try out your first tests.

Measuring Surface Water by Birthe Hohm and Ruth Schaldach is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Surface water is an important water source not only for recreational purposes. Rivers, Lakes and channels are the most easily accessible water sources, which are naturally widely spread over the planet. Surface water is part of the hydrosphere and thus depends on recharge and discharge even without human beings starting to influence these processes. Thus, surface water quantification is the first step for developing sustainable water usage practices and once implemented to monitor these.

Firstly, if you know the recharge speed of your system, you can set discharge limits. Secondly, surface water bodies should never dry out under a limit, which makes it very important to never use too much. A functioning aquatic ecosystems needs a minimum flow level to survive. However, surface water is more exposed as underground water and, therefore, more vulnerable to climatic conditions like high evaporation rates in times of drought. Additionally, this water source is also most affected by pollution as it is easy accessible and exposed. The agricultural revolution, industrialisation and urbanisation draw heavy on surface water resources, especially in regions without an implemented waste water treatment infrastructure. As dryer the region is as more vulnerable is your system and more important it is to know your surface water bodies exactly.

Therefore, measuring and mapping your water quantities gives you important directions for sustainable usage practices.

 

Measuring Groundwater Quantities

RUVIVAL Analysis

Ever wondered how much groundwater is under your feet? Then you should learn more about measuring groundwater with this e-learning tool.

Methods of Groundwater Quantification

We will provide you with some techniques, which do not need much equipment to give you already an idea on your groundwater. Everybody can help to keep an eye on our planets water resources. However, for more precise measurements more elaborate methods are needed. Have a look by yourself and try out your first tests.

Measuring Groundwater by Birthe Hohm and Ruth Schaldach is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

Groundwater quantification is also the first step for developing sustainable water usage practices and once implemented to monitor these. It follows a simple logic: You need to know how much water is there, before you know how much can be used. You need  to know how fast your system gets recharged to know how fast you can use your water reservoirs without harming your storage system. Storage systems should never dry out completely, which makes it very important to never pump your groundwater too fast to the surface and use too much. Measuring and mapping your water gives you therefore important directions. As dryer the region is as more vulnerable is your system and more important it is to know your groundwater exactly. Due to this importance several methods for measuring groundwater developed over time. However, quantification of groundwater is difficult due to many hydrological and environmental aspects that must be considered. Groundwater resources are part of the hydrosphere and thus depend on groundwater recharge and discharge even without human beings starting to influence this processes. However, agriculture and urbanisation draw heavy on groundwater resources and unsustainable practices show more and more their signs and some underground storage systems starting to dry out.

 

Nutrient Recycling Potential Calculator for Households Using Integrated Decentralised Wastewater Treatment Systems

RUVIVAL Calculator

The following calculator provides the user with the opportunity to estimate the potential fertilisation area, if faeces and urine from a household are applied. The recommended integrated decentralised wastewater system would use this fertilisation potential for non-food plants and long term soil enrichment.

Nutrient Recycling Potential Calculator

Faeces Application:

Faeces are rich in phosphorous (P), potassium (K) and organic matter and can contribute to non-food crop production both by their fertilising effect and by their soil-improving effect. The proportion of nitrogen that is in mineral form in faeces varies largely between the different purification strategies and can be lost in form of gases. Therefore, only the Phosphorus-fertilisation of Terra Preta Sanitation compost is considered.

Please find more information in this literature review.

Please Enter The Number of Household Members:

Yearly Phosphorus-Fertilisation Area of Terra Preta Sanitation (TPS) compost per Household (m2/a):

Yearly Organic Content Supply Area of  TPS compost per Household (m2/a):

Urine Application:

RUVIVAL Urine Application Calculator

Urine contains four important nutrients for plant growth: nitrogen (N), phosphorus (P), potassium (K) and sulphur (S). The direct application of nutrient-rich sanitised urine to the soil for non-food crops provide the opportunity to recover the nutrients and also reduce the use of fertilisers. The urine application calculator tool developed by RUVIVAL calculates the potential urine fertilisation area of a household based on the yearly production of urine.

More information about urine application can be found here.

Background of the Calculator

Excreta ValuesValuesUnit 
Daily Faeces Production per Person140g/d(grams per day)
Yearly Faeces Production per person51.1kg/a(kilograms per year)
Yearly Amount of Nitrogen in Faeces per Person550g/a(grams per year)
Yearly Amount of Phosphorous in Faeces per Person183g/a(grams per year)
Phosphorus Fertlisation of TPS Faecal Compost per person900m²/a(square metre per year)
Yearly Organic Content Supply Area of TPS compost per person4.5m²/a(square metre per year)

According to Jönsson et al. (2004), the potential yearly amount of nitrogen and phosphorus in faeces per person in Sweden is 550 g/(a·person) of nitrogen and 183 g/(a·person) of phosphorus. The yearly amount of nitrogen and phosphorus in faeces per household is calculated from the potential yearly amount of nitrogen and phosphorus in faeces per person multiplied by the number of household members.

According to research done in Tanzania by Krause et al. (2015), total phosphorus in TPS compost is found to be 3.6 times the total phosphorus in faeces compost. The yearly faeces fertilisation area of TPS compost per household is calculated from the potential yearly fertilisation area of faeces per person (900 mfor phosphorus) multiplied by the number of household members. The yearly organic content supply area of TPS compost per Household is calculated from the potential yearly organic content supply area of TPS compost per person (4.5m2 /(a·person)) multiplied by the number of household members.

This calculator takes as a reference point the research done by Jönsson et al. (2004), the amount and nutritional value of faeces and urine are based on the data of the Swedish population. It is important to note that amount and nutritional values of faeces and urine are subjected to variation in different regions of the world and are highly dependent on the nutrient uptake and diet of the population. The nutritional value of wastewater streams improves the quality of the urine and faeces to be used as fertilisers for non-food crops.  Therefore, the provided results should only be considered as a reference point when referring to the potential for nutrients recycling in integrated decentralised wastewater treatment.

The values used in this calculation tool are based on the following studies.

Water Saving Potential Calculator for Households Using Decentralised Wastewater Treatment Systems

RUVIVAL Calculator

The following calculator tool provides the opportunity to estimate water savings for a household through reuse of the greywater, using the recommended integrated decentralised wastewater system. Separately collected, a less concentrated greywater stream could serve as an alternative irrigation water and flushing water source after minor on-site processing.

For more information on recommended decentralised wastewater system and its proper management, please have a look at further materials provided here.

Water Saving Potential Calculator

Number of Household Members:

Water Savings per Day from Greywater Reuse and Low-Flush Toilets per Household (l/day):

Yearly Water Savings from Greywater Reuse and Low-Flush Toilets per Household (l/year):

Background of the Calculator

According to Friedler (2004), greywater reuse could decrease the water demand of a household by 48 % and lead to water savings of up to 70 litres per person per day. The yearly water savings from greywater reuse and low-flush toilets per household (l/year) is calculated from the potential daily water savings from greywater reuse and low-flush toilets per person (48 % of daily water use i.e. 70 l/day) multiplied by the number of household members and 365 days.

The value of average daily water use per person is taken to be 146 l/day per person, however, the value is subjected to variation for different regions of the world. The provided results should be considered just as a reference point when referring to the potential for water reuse in integrated decentralised wastewater treatment.

Recommended Integrated Decentralised Wastewater Treatment System for a Rural Household

RUVIVAL_Click&Play

Rural households often have to rely on decentralised systems for their wastewater treatment and sanitation needs. The following image gives an overview of a recommended integrated decentralised wastewater treatment system for a rural household. The system is based on the concept of ecological sanitation, involving separation of brown, grey and yellow water through source control schemes. It focuses on the extraction of nutrients from brown and yellow water. The reuse of greywater for non-potable purposes is also integrated in order to help to close nutrient and water cycles.

Decentralised Wastewater Treatment Literature Review

RUVIVAL Literature Review

Sustainable wastewater management in any situation is the one that is economically affordable, environmentally sound, technically and institutionally consistent, and socially acceptable for the specific situation. This paper presents a review of the advantages and limitations of various centralised and decentralised wastewater treatment options. Centralised wastewater collection and treatment systems are resource intensive and complex to build and operate, especially in areas with low population densities and dispersed households. Alternatively, the approach of decentralised wastewater treatment appears as a sustainable and logical solution to tackle problems of rural wastewater management.

Traditional Rainwater Harvesting Literature Review

RUVIVAL Literature Review

Over centuries, people in diverse geographical positions relied on rainwater and developed indigenous knowledge and techniques to harvest it. This paper introduces Traditional Ecological Knowledge and Indigenous Knowledge and provides an overview of some of the traditional rainwater harvesting methods. Bamboo drip irrigation and rice-fish farming in India are reviewed as case studies.  It is vital to take into account and to learn from what local people already know and do and apply this knowledge for our planet’s benefits. These traditional rainwater harvesting practices may have a few challenges to overcome, but they can provide water conservation strategies, especially in vulnerable regions.

UPDATE: The updated version of this literature review is part of RUVIVAL Publication Series Volume 5. A working version of this paper was previously published and discussed online. It can be read here.

Decentralised Wastewater Treatment

Decentralised Wastewater Treatment Toolbox

Decentralised Wastewater Treatment ToolboxWastewater is a key feature of public concern, especially with increased issues related to water availability, sanitation, health and sustainability. Inappropriate use and inadequate management of wastewater pose a huge threat to social welfare and ecosystems.

United Nations Sustainable Development Goals aim to ensure access to adequate and equitable sanitation and hygiene for all by 2030 while expanding recycling and safe reuse of water all around the world (Objective 6). However, as reported by WHO, around 4.5 billion people still lack access to safely managed sanitation services and 80% of wastewater flows back into the ecosystem without being reused or treated. Numerous regions of the world demonstrate a dominantly rural or peri-urban character. Sanitation data in rural communities reveal serious health, hygiene, economic and social implications that highlight the dire need to develop cost effective, more efficient and easy to maintain wastewater treatment technologies, which suit regional realities.

Decentralised wastewater systems treat and dispose relatively small volumes of wastewater, originating from single households or dwellings located in relatively close proximity with focus on the extraction of nutrients and energy, and reuse of wastewater streams. Decentralisation appears as a logical and sustainable solution to tackle wastewater management issues in rural and peri-urban areas. Numerous approaches for decentralised collection, treatment, and dispersal/reuse of wastewater exist, but there is no fixed or universal solution to the issue, making it necessary to proceed on a case-by-case basis.

Another Successful SimGame Comes to an End

Another round of the RUVIVAL SimGame has officially come to an end. Over the course of one month, teams of students from Hamburg University of Technology in Germany and ICAM in France worked hard on planning 4 new Eco-Towns in a simulated world. They were supported by external participants, who assumed the role of Eco-Town inhabitants. From Wales to Ethiopia: the task was to find ways to incorporate different water and energy solutions with sustainable agricultural practices, while taking into consideration the specific challenges connected to the different geographic, political, economical and climatic conditions.

Just as in real life, the virtual Eco-Towns live from an intense exchange and interactions that take place, which is why it is all the more important that the Simulation Game itself also continues to grow. This round gathered 119 inhabitants. To paint a picture of the exchange
taking place – together they have written 180 articles for the Game’s own Newspaper, discussing different planing options and approaches. That is 130 more than in the previous round! Over the course of the Game, the inhabitants created 450 posts and discussed these in 2700 comments and approximately 35 000 likes.

The planers got inspired from each other  and the virtual Travel Agency was particularly busy, with over 20 trips across the world being realised. With 7 travelers, Pembrokeshire in Wales was the most visited Ecotown. Above on the right you see one of the inhabitants pursing travel tickets.

Notice the Earth in the picture above? We wouldn’t do it justice if we didn’t mention the omnipresent role it played in the Game. All communication with the outside world, as well as the Travel Agency and the Newspaper were coordinated and supervised by Earth.

The closing mass online conference, with more than 50 speakers as delegates for their subgroups, took place last week. The participants were logged in mainly from Hamburg, Paris and Toulouse. Is it possible to build bicycles from bamboo grown in constructed wetlands used for greywater treatment? How can we encourage sustainable behaviour without an restrictive penalty system and non authoritarian approached ? Which water storage system is the most suitable one for the specific climate and geographical conditions? These questions and more were answered during the final presentations.

The planning process in all Eco-Towns  benefited greatly from such a fruitful exchange. As the Simulation Game continues to grow, we look forward to the learning and knowledge transfer and exchange that is to come! We will let you know when the next round is on!

Biowaste Usage

Biowaste Usage Toolbox

Biowaste Usage ToolboxBiowaste stands for discarded biodegradable material. This means it can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms under anaerobic and aerobic conditions. One of the main reasons why biowaste represents a threat to the environment is the production of methane during its decomposing in landfills. This environmental impact can be significantly reduced through separate collection and use of biowaste.

In terms of usage potential, meaning soil or energy recovery, biowaste is still largely underutilised. Employing traditional practices in recycling, reusing and composting can significantly decrease uncontrolled waste disposal, which is especially important in regions without access to formal collection services. Composting, for example, can even ensure the generation of good quality natural fertiliser, which is why this practice should be encouraged.

RUVIVAL in practice: Project newTree

This week we introduce you to another sustainable  rural development project which is implementing exactly those practices RUVIVAL is set to teach: meet newTree!

We have also partnered up to create learning materials about the practices they are implementing, so make sure to have a look at the newTree Semi-Circular Bunds example!

newTree: Local women carrying the harvest
Local women carrying the harvest

In Burkina Faso, a landlocked country in the African Sahel region, over 80 % of the population lives from subsistence farming. Population growth, deforestation and the effects of climate change accelerate the degradation and erosion of soils, thus threatening rural families’ livelihoods. Since 2003, newTree has been developing and implementing an effective approach that supports local communities in restoring ecosystems and soil fertility, improving living conditions and gaining new sources of income. The participatory newTree approach is based on the principle of knowledge transfer: through awareness building, instructions, coaching and provision of basic materials, newTree ensures that farmers and women’s groups can replicate methods autonomously and sustainably.

newTree Activities

newTree activities are centered on four pillars which together form a holistic, sustainable agroforestry system. First, the natural regeneration of ecosystems is achieved through the fencing of land, which offers protection from grazing and woodcutting. Gradually, the natural vegetation recovers, first through grasses, later through shrubs and trees, which build a critical basis through their root system and shade.

Farmers are then instructed in effective, sustainable and organic agricultural methods, which improve water retention, erosion protection and fertility. Farmers can either apply these methods within or outside of their protected sites. Critically, the resulting natural regeneration not only restores ecosystems, but also provides local farming communities with new and sustainable sources of food and income.

To reduce the need for firewood and logging – over 80 % of cooking in Burkina Faso is done on open fireplaces – newTree instructs women in building improved cooking stoves. The improved stoves reduce wood consumption by 60 %, which amounts to almost 2 tonnes of wood per year and household. The stoves are built by the women themselves, based on traditional methods and using locally available materials.

The making of improved cooking stoves

Finally, farmers and women’s groups receive training in activities to develop new, wood independent sources of income. Depending on local conditions and demand, these activities can range from beekeeping and honey production to hay, seedling or vegetable production, the transformation and commercialization of non- wood forest products or the raising of livestock such as sheep, goats or cattle.

To date, newTree has enabled the set-up of over 300 enclosures protecting 600,000 trees, the sustainable cultivation of close to 20,000 ha of degraded land and the construction of 65,000 improved cooking stoves. Together with its local partner tiipaalga, over 150,000 inhabitants have been reached, which amounts to 5 % of the population in the newTree project areas. These achievements motivate the local team of 53 employees even further to establish tiipaalga as a guiding light in the promotion of sustainable agriculture and improved living conditions of rural families in Burkina Faso.

Soil Erosion Calculator

RUVIVAL Calculator

The average annual rate of erosion on a field can be predicted with the use of the Universal Soil Loss Equation (USLE). This equation integrates the local rainfall pattern, soil type, topography, crop system and management practices. The following Soil Erosion Calculator is a Tool to calculate the average annual rate of erosion. It is based on the USLE equation and can be applied globally.

Nevertheless, the USLE equation and thus the Soil Erosion Calculator has two main limitations that need to be considered. Firstly, the calculator is an estimate based on ample and variable factors. These factors may vary with changing climate conditions, alternating usage of the soil, etc. Therefore, the resulting soil loss must be viewed as a long-term average. Secondly, the calculator only accounts for soil losses due to sheet or rill erosion on a single slope. Soil losses associated with gully erosion, wind erosion or from tillage are not included.

After calculating your Soil Erosion Rate, you can use the following table to find out about your Soil Erosion Class. Depending on your class, you may consider to implement Soil Erosion Strategies on your field. Play around with the factors you inserted priorly, to see if there is a particular factor that influences your Soil Erosion Rate strongly.

There is a computerized version of the USLE equation, named Revised Universal Soil Loss Equation (RUSLE). RUSLE is an improved formula, that can handle more complex combinations of tillage and cropping practices and a greater variety of slopes. A further-enhanced version the software is RUSLE2, which can do event-based erosion prediction. RUSLE2 requires a comprehensive set of input information, which may not be available in all jurisdictions.

The Water Erosion Prediction Project (WEPP) is a physically-based soil erosion prediction technology. It integrates hydrology, plant science, hydraulics and erosion mechanisms to predict erosion at the hillslope and watershed scale. It is capable of modelling and assessing a variety of land uses, climate and hydrologic conditions. It can be run offline on personal computers supporting Windows.

Upcoming RUVIVAL Events: Simulation Game and ICAM Guest Lecture

Simulation Game

May is just around the corner and with it some exciting RUVIVAL events, most notably – the new round of the RUVIVAL Simulation Game! Next week, we will start accepting applications for external participants – the application form and further instructions will be available on our website, so make sure to stick around!

Quick recap about the Simulation Game:

It is an interactive learning tool for planning eco-towns. The planning takes place in a simulated world, on the platform HumHub. The aim is to employ ecological design using system thinking and synergetic effects of resource cycles. The planning groups, consisting of students from participating universities, exchange their knowledge, as they experience similar obstacles in the planning process despite being in a different environment. Each planning group has subgroups focusing on water, energy, buildings, transport or community impact, just to name some aspects.

Simulation Game Platform

As an external participant, you play the role of a future inhabitant in one of the newly planned towns. You are able to take action and influence the planning progress. Still not sure if the Simulation Game is for you? Read more about the Simulation Game, as well as about the experiences from the previous year.

Background on Raw Earth as a Sustainable Building Material

Although raw earth as a building material existed for a long time, it only recently gained interest, due to its eco-friendly properties and significant energy saving potential across all stages of its life cycle. Therefore, raw earth can be a cornerstone for constructing eco-houses.

Unlike conventional masonry bricks, the soil and water mix in raw earth is used almost in its natural state. There is ample evidence, both historic and contemporary, that raw earth can be a durable construction material. Famous raw earth constructions include the Fujian Tulou in China and the new Ricola Kräuterzentrum (German for herb center) in Switzerland by the famous architecture firm Herzog and de Mauron.

However, shifting cement to raw earth construction will require to overcome not only technical, but also cultural challenges. One major challenge is to overcome the prejudices, that raw earth constructions are not suitable for contemporary architecture. Furthermore, to break the perception, that cement is not automatically better as it is a more recent construction method. Regardless of this challenge, the interest in raw earth as a building material and alternative to cement increased.

About the lecturer

Madiana Hazoume gives this two part lecture on Raw Earth Construction. She is a lecturer and project manager at ICAM Paris in 2018, responsible for the thematic area Sustainable Buildings and Cities.
