Klimaschutzprojekt Uganda: Solare Wasserdesinfektion
Addressing a variety of challenges
According to the WHO, about 70 percent of Uganda's rural population has no access to clean drinking water. Water is disinfected by cooking over open wood fires, but this also causes health problems. Many people already suffer from serious lung diseases caused by air pollutants from inefficient wood burning. Furthermore, Uganda has one of the highest deforestation rates in the world. An intact environment, clean air, and safe drinking water are, however, the prerequisites for a good life and are indispensable for education, ecological and social sustainability, and the fight against poverty.
Innovative approaches through a broad cooperation network
The use of solar water disinfection (SODIS method) drastically reduces the amount of firewood needed, which should save about 20,000 tonnes of CO2 in the next five years. Furthermore, this project will also counteract the development of harmful smoke in households. The cooperation between the BOKU Institute for Sanitation, Industrial Water Management and Water Pollution Control, the Water School Uganda, and the Makarere University in Kampala ensures a holistic approach to the project.
Water disinfection by UV radiation
2000 households in Soroti are being familiarised with the use of solar water disinfection (SODIS method) as part of the BOKU climate protection project. The Austrian start-up HELIOZ provides each household with a device for measuring UV radiation (WADI) that has been tried and tested in Africa and Asia. This makes it easy to check and guarantee the disinfection of drinking water. In addition to the CO2-mitigation, the project also brings additional social and ecological added value.

Decentralized Composting in Addis Ababa / Ethiopia
Klimaschutzprojekt in Äthiopien: Kompostierung
CO2-mitigation through composting of organic waste
Untreated waste due to lack of waste separation, low recycling efforts and inadequate landfilling is a major burden on the environment and the local population. Therefore, the aim of this BOKU climate protection project in Addis Ababa is to convert about 8,000 tonnes of organic waste per year into nutrient-rich compost, reducing about 200 tonnes of CO2 annually.
Involvement of local partners as an important success factor
Households, waste collectors, and other local stakeholders are trained in how to separate waste into organic and other material and collect it properly. The collected organic waste is processed in a composting plant commissioned as part of the project. Trained local workers learn how to control and monitor the composting process to ensure that the compost is of good quality. The compost obtained is then sold as high-quality, regional fertilizer and offers the local actors involved an additional income and safe working conditions.
Commitment to equal opportunities
Through the strong involvement of single women, the project also contributes to local social empowerment. This pilot project is intended to be the starting signal for further decentralized composting projects in Ethiopia. Not least through the show garden, a network for the exchange of knowledge and experience is to be created in order to establish decentralized and low-CO2waste management in Ethiopia. In addition to sinking CO2 and improving the quality of the soil, the general nutritional situation can also be influenced.

Reforestation and Regeneration of Local Forests in North-Gondar / Ethiopia
BOKU Climate Mitigation Projects
60 hectares of fallow land grow into a coppice forest
As a successor to the successfully completed carbon sequestration project, "Afforestation and natural reforestation in North Gondar / Ethiopia" , an adjacent area was approved for reforestation. Through sustainable management of the pasture land and so-called fencing areas, 60 hectares are specifically protected from grazing and can thus grow into coppice forest.
Local population, economy, and biodiversity benefit
Similarly to the percussing project, separate goals are being pursued in this ongoing project in addition to the CO2carbon sink of at least 11,000 tonnes: (1) the strengthening of local economies through the availability of wood, animal feed, and additional income from "non-timber forest products" such as honey, seeds, resins, etc. (2) The natural regeneration of regionally adapted trees and (3) the increase of local biodiversity as well as water and soil protection.
Self-determination of the village community and tree nursery program guarantee long-term success
The village communities manage the collective forest area together in a participatory process establishing common rules for the management of the new areas. Furthermore, the project will support the development of the local tree nursery programme for seedlings of native species and local "Farmer to Farmer Training" to further contribute to the development of additional sites for fencing areas in the region and for the afforestation of further areas in the region

Reforestation, Forest Protection and Agroforestry in Siwalik and Gauri- Sankar / Nepal
Klimaschutzprojekt in Nepal
Counteracting the pressure on local forests
In Nepal, large areas of forest are disappearing, while grasslands and shrublands are steadily increasing One reason for this is deforestation for short-term fertile farmland. The 2015 earthquake also increased the pressure on forests as a resource for construction and firewood. The main objective of this BOKU climate protection project is to reforest around 80 hectares in the Gauri Sankar and Siwalik regions, of which 20 hectares are earmarked for agricultural use. In addition, 500 efficient biogas stoves will be put into operation.
Combination of forestry and agriculture as key to success
Besides ecological aspects, economic, and social aspects are in the foreground. To counteract forest degradation and its negative social consequences, national and local stakeholders were therefore involved in the selection of the regions in a participatory manner. The decisive factor in the selection of Gauri-Sankar and Siwalik was that they have great potential for establishing a sustainable agroforestry system that can serve as an additional source of income for the local population.
Einbindung lokaler Akteur*innen und Wissenstransfer
A reforestation and management plan was drawn up with the management committees of Gauri Sankar and Siwalik (among others), best practice examples were presented and training sessions were held. The training courses in sustainable agriculture and forestry (forest management, seedling propagation and forest fire protection) and the commissioning of tree nurseries ensure the sustainability and stability of the project and are well received by the local population. In this win-win situation, CO2 is mitigated by reforestation, further emissions and harmful flue gases are reduced (cooking stoves), and a new economic basis is created.
