The European Centre for Development Policy Management asked me to make two maps for their report “Sustainable food systems through diversification and indigenous vegetables: An analysis of the Arusha area”. The report describes the food system(s) of rural, peri-urban and urban areas in and around Arusha (Tanzania, Africa), diagnoses the drivers and constraints for better integration of indigenous vegetables, and helps to decide on pathways towards more sustainability. The maps show the locations, types and intensity of the research. ecdpm.org
