LEAP-RE – RE4AFAGRI aims at developing the state of the art of climate-water-energy – land-food-environment nexus modeling in rural areas of developing countries to bridge the current gap between large-scale and local-scale analysis approaches. The project aims to provide a set of open-source validated tools developed through analytical and empirical approaches that can be exploited by stakeholders in future applications. In addition, LEAP-RE – RE4AFAGRI aims to design business models that allow the implementation of integrated technological solutions in rural areas, based on identified best practices, regulatory obstacles and opportunities through the participation of African companies, public authorities and consortia of small owners. The ultimate goal is to support policy makers in defining policy frameworks that ensure that the identified business models can be successfully implemented by local entrepreneurs, while also meeting the technical and environmental requirements to achieve development goals in rural areas.
