Opportunities for managing solid waste flows in the periurban interface of Bamako and Ouagadougou

Abstract

This paper examines the links between solid urban waste management and peri-urban agriculture in Bamako and Ouagadougou. Staple crop farmers in the vicinity of both cities value urban waste as a source of organic matter and are prepared to pay for it. Cultivation on degraded soils has even been revived in some cases thanks to this readily available resource. However, uncertain land tenure means that farmers have little incentive to ensure the safe disposal of dangerous elements in solid waste. Current plans would eliminate this recycling practice and promote largescale composting, but the cost for farmers will be too high, leaving them with an incentive to make their own illicit arrangements for acquiring waste material. Furthermore, small enterprises and associations that have come to play a complementary and innovative role in waste management would be forced out. The key challenges for policy are to build on economic and institutional reality and to regard urban waste not as a dangerous nuisance but as a source of nutrients for agriculture. Opportunities exist to deliver waste that has been sorted, though not composted, to peri-urban farmers.
