The CSA-Farm Calculator tool was developed as part of the CSA Multilevel Monitoring Framework implemented in the context of the Learning Platform Participatory evaluation of Climate-Smart Agricultural (CSA) practices and technologies across the AR4D Climate-Smart Villages (CSVs) network. It builds on a farm model included in the GeoFarmer app allowing the prospective assessment of farm performance in response to the implementation of different CSA practices/packages and other farming management activities in terms of productivity, adaptive capacity, and mitigation potential (in other words the “climate-smartness” of the farm) and specifically looking at synergies and trade-offs.
