Building climate-resilient cities Ecological sanitation and waste management, and organic urban agriculture for emerging cities in Sub-Saharan Africa.



Urban Agriculture in Addis Ababa

Network Project between ClimEtSan (Forschungszentrum Jülich & Wondo Genet School of Forestry and Natural Resources) – IN³ (Bauhaus-Universität Weimar & Ethiopian Institute of Architecture, Building Construction and City Development)
Funded by German Federal Ministry of Education and Research (BMBF), 2018 - 2021

The urgent need for climate-resilient cities has arisen as the most adverse impacts of climate change are likely to be in urban areas where people, resources, and infrastructure are concentrated. Here, climate change will not only increase the frequency of disasters, such as heat waves, droughts, heavy rains, flooding, and water- and vector-borne diseases, but also their intensity and destructive impact. Urban population can also be seen as vulnerable to food supply because of a lack of self-sufficiency and the resulting dependence from external supply and market prices.
This interdisciplinary and interinstitutional project includes urban planners, architects, environmental scientists, agronomists, engineers, microbiologists, and networkers. The multi-disciplinary group is aiming to combine ecological sanitation, urban agriculture, biochar, urban-rural metabolism, and city planning for practical solutions in the context of climate-resilient rural and urban development in Ethiopia.
Through this project, data and planning tools will be used to support the modeling of more climate resilient cities. The project therefore aims to generate data from organic urban agriculture (including soil amendments of biochar from biochar cooking stoves, compost of organic waste and human excrement) and use this data to understand how different metabolisms can be integrated for future cities, especially for guiding and supporting planning decisions of emerging cities. In spring 2019 the test sites had been adapted and organized to generate samples in the urban context of Addis Ababa.
