AfricaNUANCES-STP AfricaNUANCES, a Specific Targeted Project (STP) of the EU, focuses on mining of experimental data available of single solutions to farmers. Examples are use of leguminous crops as green manure, fodder for livestock or as multi purpose crops aiming at improving soil fertility and overall production. Operating at the level of cropping and livestock systems make adoptation of these single technologies cumbersome if not the livelihood as a whole is considered. The programme thus further aims to use the existing knowledge on technologies to be evaluated with an integrated framework FarmSim. Using this framework, current farming systems are Described and Explained, and future systems are Explored and Designed (DEED).
