Numerous projects across the globe have supported the identification and implementation of good ag-ricultural practices to advance climate change adaptation. Yet, few manage to sustain the positive ef-fects after the project period. The SCARF-project will address the root-causes of non-adoption of agri-cultural good practices. The goal is to promote long-term resilience of smallholder farmers in rural Tan-zania. Based on an innovative combination of scientific climate impact and adaptation assessments, participatory tools and implementation activities, agroforestry measures will be selected, analysed, co-designed, implemented and scaled up. The systemic nature of agroforestry and its various environmen-tal and socio-economic benefits make it a particularly promising climate change adaptation strategy. The project aims to understand and foster conditions that lead to the upscaling of agroforestry in both time and space.
