<p>Climate change threatens vulnerable communities in sub-Saharan Africa who face significant challenges for adaptation. Agriculture provides the livelihood for the majority of population. High-resolution assessments of the effects of climate change on crop production are urgently needed for targeted adaptation planning. In Ghana, next to food needs, agriculture plays an important role on international cocoa markets. To this end, we develop and apply a National Agro-Ecological Zoning system (NAEZ Ghana) to analyze the impacts of high-end (RCP8.5) global warming on agricultural production potentials until the end of this century. NAEZ Ghana uses an ensemble of the CORDEX Africa Regional Climate Model, a regional soil map, to assess development trends of crop production potentials for 19 main crops. Results highlight differential impacts across the country. Especially due to the significant increase in the number of days exceeding high-temperature thresholds, rain-fed production of several food and export crops could be reduced significantly compared to the historical 30-year average (1981-2010). Plantain production, an important food crop, could achieve under climate change less than half of its current potential already in the 2050s and less than 10% by the 2080s. Suitable areas for cocoa production decrease strongly resulting in only one third of production potential compared to today. Other crops with detrimental effects of climate change include oil palm, sugarcane, coffee, and rubber. Production of maize, sorghum, and millet cope well with a future warmer climate. The NAEZ Ghana database provides valuable high-resolution information to support agricultural sector development planning and climate change adaptation strategies. The expansion of irrigation development will play a central role in some areas. This requires further research on Ghana’s linkages between food, water, and energy, taking into account climate and socio-economic changes.</p>

The Impact

International climate finance plays a key role in enabling the implementation of adaptation measures. However, while there is a common metric for gauging the effectiveness of finance for mitigation – greenhouse gas emission reduction per unit of funding – no corresponding metric exists for adaptation. Instead, assessments of what works best in adaptation finance focus either on procedural aspects of funding modalities, such as equity in the allocation of funding, or on the extent to which specific adaptation activities produce the desired results. This mixed methods systematic review aims to assess the effectiveness of adaptation finance and bridge the gap between those two approaches. It involves a transparent and comprehensive synthesis of the academic and grey literature on how different characteristics of adaptation projects in sub-Saharan Africa – and finance for those projects – affect adaptation outcomes, particularly in terms of risk and vulnerability to climate change impacts. Finalised adaptation projects funded by a set of the multilateral climate funds and two bilateral donors (United Kingdom and Sweden) are the focus of this review. The findings can help inform the future design and implementation of adaptation activities as well as funding decisions.
