Climate-smart agriculture (CSA) is being widely promoted as a solution for food insecurity and climate change adaptation in food systems of sub-Saharan Africa, while simultaneously reducing the rate of greenhouse gas emissions. Governments throughout Africa are writing policies and programs to promote CSA practices despite uncertainty about the ability for practices to meet the triple CSA objectives of CSA. We conducted a systematic review of 175 peer-reviewed and grey literature studies, to gauge the impact of over seventy potential CSA practices on CSA outcomes in Tanzania and Uganda. Using a total of 6,342 observations, we found that practice impacts were highly context (i.e. farming system and location) specific. Nevertheless, practice effect across CSA outcomes generally agreed in direction. While our results suggest that CSA is indeed possible, lack of mitigation data precludes a more conclusive statement. Furthermore, the inclusion of potential adoption rates changes the potential of CSA practices to achieve benefits at scale. Given the uncertainty and variable impacts of practices across regions and outcomes, it is critical for decision makers to prioritize practices based on their desired outcomes and local context.

Drought is the single greatest climate risk faced by most farmers in Eastern and Southern Africa. In discussions of climate risk, it is crucial to distinguish between meteorological drought (lower-than-average annual or seasonal rainfall) and agricultural drought (insufficient water at critical stages of crop growth). Global climate change models do a poor job predicting either type of drought (or flooding), and there appears to be little relationship between drought and rising levels of greenhouse gases. Drought and flooding are more closely correlated with El Niño-Southern Oscillation (ENSO) events, which appear to predate global warming.

Agricultural production in Eastern and Southern Africa (ESA) is broadly characterised by high climate risks. Rainfall is variable in timing, amount, and intensity. Both drought and flooding are common. These challenges are magnified by the fact that the majority of farmers in this region face severe poverty, resource constraints, and food insecurity. More than 90% of these farmers are dependent on rainfed production. The rise in global greenhouse gases appears to be increasing these climate risks.

This paper briefly summarises available information on current climate risks in ESA, and then shows how these risks are expected to worsen by the middle and end of the century. It discusses the implications of these changing risks for agricultural investment and for prioritising the pursuit of more climate smart agricultural systems. A key theme underlying this discussion is that a better understanding of, and response to, current climate risks will provide a strong foundation for improving resilience to climate change in the future.

This Literature Review is the rst step towards a comparative assessment of Weather Index Insurance (WII) in the agricultural sector in East and Southern Africa. The second step involves visits to four countries (Kenya, Tanzania, Zimbabwe, and Zambia) covered by the Climate Smart Agriculture Programme (Vuna) funded by DFID, which have weather index insurance programmes. The visits will allow collection of information on the recent performance of those programs and obtain the perceptions of key stakeholders on lessons learned, constraints, sustainability, and potential of those insurance programmes to address issues related to strengthening the resilience of agricultural systems to weather risk. The ndings from both stages will be summarised in an Evidence and Learning Report focussing on the determinants of success or failure of the programmes under implementation.

This paper summarizes the main findings of the global experience on the implementation of WII specically the lessons learned on the mechanics of the index, pro tability, bundling, impacts, and potential role in climate change adaptation. It also discusses the challenges of current pilot projects in East and Southern Africa, wherever secondary information is available.
