Significance: We collated a unique dataset covering land use and production data of more than 13,000 smallholder farm households in 93 sites in 17 countries across sub-Saharan Africa. The study quantifies the importance of off-farm income and market conditions across sites differing strongly in agroecology and derives generally applicable threshold values that determine whether farm households have enough food available to feed their families. These results show there is a strong need for multisectoral policy harmonization and incentives and improved interconnectedness of people to urban centers and diversification of employment sources, rather than a singular focus on agricultural development of smallholder farmers in sub-Saharan Africa.

Building climate resilience, defined as the ability to anticipate, absorb, accommodate, or recover from climate change in a timely and efficient manner, is becoming a major priority of development across multiple sectors. However, there is still no consensus on how resilience should be assessed despite the release of numerous theoretical papers on the topic. Various measurement frameworks and recommendations have emerged, but their applicability is yet to be critically assessed. Using a comprehensive review and a systematic selection approach, we review resilience assessment tools developed for the context of climate change and agricultural development, and their linkages to theoretical frameworks, with a particular focus on the choice of indicators and the scale and methods of measurement. Fifteen tools originating from diverse organizations were selected and evaluated according to a measurement framework. Our study finds that, while some of the tools remain embedded in classical approaches, by simply adding a resilience lens to previous tools and by recycling indicators, others demonstrate a true attempt to re-think in order to account for resilience dimensions. We conclude that for the use of resilience assessment tools, a major challenge is to ensure that simple and operational tools can address complexity. Full baseline should comprise both quantitative and qualitative data collection, and include more systemic indicators as well as indicators of stability and shocks. Changes should be tracked with regular monitoring and evaluation using simple tools based on key variables that capture short-term adaptive processes and changes in states, at the appropriate system level. Clear pathways to human well-being, including transformation, should be discussed through system-oriented approaches, to discard potential undesired resilient states. Finally, robust outcome and impact records from the use of these tools are needed to demonstrate whether the resilience concept is useful over time in driving development into more desirable paths
