How "visible" is urban agriculture in Cameroon? Mapping urban agriculture practices by satellite imagery and field surveys

Urban Farm DB summary

Urban agriculture appears in many sustainability agendas yet has been ignored in the public policies of many African countries. Combining multi-scale mapping (city and neighbourhood) with semi-structured interviews in one large and one medium-sized Cameroonian city, this study tests how well those techniques characterise urban agriculture for local decision-making. Mapping from 5-metre SPOT satellite imagery gives a general grasp of the spatial distribution of practices, but crop types, emerging entrepreneurial practices and the temporality of crops are invisible to it and surface only through field mapping and interviews. Echoing critical remote-sensing scholarship, the authors propose a methodological framework for profiling urban agriculture and argue that the choice of research method shapes our understanding of it, so it should be made with each city's specific characteristics in mind.
