Case study description

The innovation under study

The project explored the potential of integrated management of various residues (e.g. livestock manure, agro-industrial waste, municipal green waste, sewage sludge) on a regional level to provide products that satisfy both farmer preferences and crop fertilizer needs. The short-term development objective was to produce consolidated integrated management scenarios.

The main intended innovations were (1) the implementation of a product-oriented region-wide organic residue management system for western Réunion or beyond, and (2) the adoption of the resulting fertilizers by various farmer groups. Impact assessment is still underway but one major outcome could be a contribution to a region-wide change in paradigm as regards how organic residues are considered: from hazardous waste or “cheap but unreliable fertilizers” to inputs for a local fertilizer industry. “Unintended” innovations were explicitly encouraged by the open process, designed to maximize workshops as learning opportunities.
