Open Source Solar System

Posted on

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.

Assembly of a Solarbox

This tutorial shows you how to connect the previous constructed charge controller with solar panels, batteries and loads directly. However, a solarbox can be created individually.

Another cos(h) tutorial shows how to assemble a solarbox, which is a small scale mobile energy system (consisting of batteries, electric components like a charge controller and connectors for connecting power generation units like solarpanels)

Aquaponic Farming using the Asian Clam

Posted on

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.

Digital Changemaker group visits the TUHH

Posted on

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

Posted on

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.

Our Institute of Wastewater Management and Water Protection was represented by Prof. Dr.-Ing. Ralf Otterpohl, who presented his New Town concept, Stefan Hügel, who showed his recent research on Pondfarming – The Potential of Floating Plants, Stefan Deegener, who held a workshop about ecological sanitation and Tina Carmesin, who represented our RUVIVAL team.

Poster Conference on Permaculture, Sustainability and Water La Gomera
Programme of the Conference on Permaculture, Sustainability and Water on La Gomera (in German)

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.

The meeting was organised by Finka Alexandria and Allerhand am Alpenrand in cooperation with the Institute of Wastewater Management and Water Protection, RUVIVAL, AIDER (Insular Association of Rural Development of La Gomera) and the Island Council of La Gomera.

Geological Background for MAR Systems

Posted on

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.

New Making of RUVIVAL Section

Posted on

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

Posted on

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. Beyond this, the newest project addition RUVIVAL Community is helping to bring invaluable knowledge sources and practice examples.

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

Posted on

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 in the RUVIVAL Community. It can be read here.

Rural Energy Systems

Posted on

Universal 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

Posted on

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.

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

Posted on

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.

Creative Commons LicenseWater 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.

Literature Review

World Soil Resources Literature Review

Posted on

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.

This is a working paper reflecting ongoing work. Comments and suggestions are welcome, please use our Contact form. An updated version will be published as part of RUVIVAL Publication Series Volume 4.

Measuring Surface Water Quantities

Posted on

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.

Creative Commons LicenseMeasuring 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

Posted on

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.

Creative Commons LicenseMeasuring 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.

Calculation

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

Posted on

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 Faeces Production
per Household (kg/a):

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.

Click On the Calculator Icon to Access the Urine Calculator

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

Posted on

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

Posted on

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. Please click on the hotspots in the image for more information.

Animals in Permaculture Quiz

Posted on

It may not seem right on a first glance to raise animals in permaculture systems. However, when done on a correct scale, raising animals on a small piece of land can offer balance and sustained fertility, with improved quality of the food products. Animals eat from pastures, as well as from waste products from the land, while at the same time offering fertility and numerous food products for us humans. Check your knowledge of the potential role animals can have in permaculture in the quiz below!

Conventional livestock production has severe impacts on the environment, which affect its every medium. Click on the hotspots below to learn more about these impacts! Keep in mind that this image is meant as symbolic, in order to draw direct connections between livestock and the environmental medium at hand. In reality, animals in conventional farming systems are usually raised in confinment, in so called animal feeding operations (AFO) or confined animal feeding operations (CAFO). Not only does this way of keeping animals affect the environment, but it also has severe negative imacts on animal livelihood.

Literature Review

Decentralised Wastewater Treatment Literature Review

Posted on

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.

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 in the RUVIVAL Community. It can be read here.

Traditional Rainwater Harvesting Literature Review

Posted on

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.

This is a working paper reflecting ongoing work. Comments and suggestions are welcome, please use our Contact form. An updated version will be published as part of RUVIVAL Publication Series Volume 4.
