African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.

This paper discusses the key components of the technical and institutional innovations developed to address this food and nutrition security concern in Zambia using locally bred varieties registered with the Seed Control and Certification Institute (SCCI). The institutional collaborations arising from this Innovation Platform has brought together various organizations/institutions in the innovation process and led to the capture of up to 5% of the market share.
