    Greenfarming at the Cottica II

    Jan 24, 2020
    We're almost at the end of our project,just one more week to go. Four of the five tables we built are now installed at the local farmers. Some farmers pick up the technique faster than others, and some farmers even came up with their own ideas to fix certain problems. We discovered that it is difficult to control the amount of sunlight, because too little light causes the plants to hang and too much will burn them. We started experimenting with agro-plastic, a transparant sheet of plastic which will be stretched above the plants. This will protect the plants from the heavy sunlight and keeps rainwater from entering the system, so that the concentration of nutriënts is more stable. In our last week we will mentor the farmers in a way that they can buy new parts of the system and can fix problems when we are back in Holland.

    Green Frugal Energy update IV

    Jan 21, 2020

    Last week the construction of HS’s very own biogas digester commenced, and it has been very uplifting to see the project we envisioned becoming a reality. When we arrived at the office, a big hole had been dug, and the following days a mason worked hard on the construction of the dome. At the moment of writing this update, the gas tap and the PVC pipes for input have been connected, and the gas-tight coating has been applied on the inside. Since we will only be here for another three days, we will not experience the first gas production. However we are very glad our plan could be executed. Also on behalf of our supervisor Henry, many thanks to S4S for enabling this execution! We will send our next and fnal update after finalisation. Until then we will be finalising our business model proposition by means of a presentation and enjoy our last days in this beautiful country.

    Frugal Hydroponics - update I

    Jan 16, 2020

    After a month of interesting appointments in Paramaribo, we started implementing our practical plans. In the first weekend of December, we realized an educational greenhouse of 24m2 at the local elementary school in Klaaskreek. We did this together with the guys from Suriname Organic Hydro Crops. We stocked up the necessary materials along the way from Paramaribo to Klaaskreek. For the frame of the greenhouse, we have chosen for Walaba-wood, a sustainable type of wood that is resistant to termites and furniture beetles. The roof consists of shade mesh (50%) and agricultural plastic to allow the right amount of sunlight. We have chosen to have the roof staggered so that the heat does not collect in the top. The construction of the greenhouse was quite a challenge, especially because there were hardly any tools available. Fortunately, we were able to borrow the necessary tools from a number of helpful neighbours and achieved the result we were hoping for.

  • Green Frugal Energy

    Green Frugal Energy in Uganda

    We are an interdisciplinary team of three students from Leiden and Delft doing research on the implementation of biogas energy in Uganda from the 6th of November 2019 to the 25th of January 2020. The team consists of IJsbert Bekooy (TUD), Danique François (LU) and Friso Siemensma (LU) and is part of the minor ‘Frugal Innovation for Sustainable Global Development’. This minor is a multidisciplinary programme between the TU Delft, Leiden University and Erasmus University Rotterdam.

  • Co-curation “Palermo hosting city” exhibition

    Medhak is a project designed with the hope to achieve an increase of the social cohesion in Palermo, a city permeated by the current humanitarian crisis in the Mediterranean.

  • Muima

    For the minor International Entrepreneurship & Development, we (Coco Polderman, Line Hietink en Christine van Diemen) are going to Kenya. In Kenya we will help developing a new product for Muima Industries.

  • Maldives Matter

    The Maldives, an 800 km long island group in the Indian Ocean. The lack of agriculture due to climate and knowledge result in a big problem: 90% of its food is being imported. This results into a high CO2 emmission due to transport (the food comes from all over the world), a big cashflow that doesn’t stay at the local communities, a high dependency on foreign countries and lack of knowledge and education because of a lack of this industry. Our plan is to realize a high-tech greenhouse in the Maldives.

  • Team Zoom


    Schistosomiasis is a parasitically neglected tropical disease that mainly occurs in Sub-Saharan Africa. More than 250 million people are infected and 700 million have the chance of infection. This parasite is mainly found in still standing water sources. The danger of this parasite is that it penetrates through the skin surface. After this it multiplies in the bladder and transforms into worms that move through the bloodstream to all organs and then affect them.

  • Sustainable Siyakhana

    In 2005 on a hectare-sized piece of land located in the middle of Bezuidenhout Park within the inner city of Johannesburg, Prof Michael Rudolph, together with colleagues and community representatives, established Siyakhana, a food garden and social entrepreneurial enterprise that has evolved into a platform for research, training and a capacity-building incubator and resource hub. Our project is to design and build a small biodigester to recycle and re-use organic waste that is created in the Siyakhana garden. With the help of this biodigester, we will give workshops in order to teach the farmers about sustainable farming and entrepreneurship, e.a. selling the produced biogas and fertilizer from the biodigester. Evans Muchesa, a PhD student from the university of Johannesburg will oversee the process of social entrepreneurship in order to ensure the continuity of the project after our departure

  • Aquaponics Cape Town

    The Problem
    The drought is a huge problem for the growing population of Cape Town, South Africa. Especially the communities in the “townships”, the suburbs in which during the Apartheid “non-whites” lived, are struggling with the water scarcity. On top of that, gangs, thieves and junkies are causing an unsafe environment, especially for children.

  • Energizing Uganda

    We are three students from the TU Delft. We are going to work on a biogas project in collaboration with the Ndejje University in Kampala. We want to contribute by bridging the gap between the sanitation and energy problem in Uganda. 

  • Uplifted Zanzibar

    Zanzibar is a tiny island at the coast of Tanzania. It is known for its breath-taking white beaches and clear blue waters. However, this beauty is as much a blessing as it is a curse. Tourism is an important income generator for the island but also generates a huge amount of waste.  A local company named Chako transforms this downside of tourism into a great opportunity: to reduce the waste and help employ the local youth and women. This is very important given the fact that half the population on Zanzibar lives below the poverty line.

  • Electric Fence Bardiya

    For our project in the context of our minor International Entrepreneurship & Development we will be going to Bardiya National Park, in the southwest of Nepal. In the buffer zone around the National Park many farmers settled on the fertile grounds. As these grounds and farms attract elephants, the elephants rage the villages and farms in search of food.
