Exploring the social-ecological potential for indigenous agroforestry in peri-urban areas: a participatory mapping approach

Peri-urban agroforestry can provide affordable, fresh, and nutritious food and a departure from conventional forms of cropping. Indigenous foods are well-adapted to local conditions, and may hold cultural and economic value for peri-urban residents. Social, ecological, and economic variables influence the feasibility of indigenous agroforestry in peri-urban areas. This study uses participatory mapping and geographic information systems (GIS) to assess these variables and to map suitable spaces and species for peri-urban indigenous agroforestry at three peri-urban sites in Durban, South Africa. We find that: land tenure, livelihood opportunities, and indigenous food perceptions factor into socioeconomic preferences; topography and soil quality influence ecological feasibility; access to water and roads influences perceived economic viability. Although GIS techniques can identify land suitability, participatory mapping adds local fine-scale context to enhance decision-making. Based on the social-ecological conditions at the three sites, we suggest specific configurations of locally adapted foods and farm designs for peri-urban agroforestry. Our study demonstrates how agroforestry is more feasible in places where basic living conditions are fulfilled, and how co-design can improve recognition of local needs, accessibility to services, and balancing urban green equity.
