Impacts of climate change on agro-climatic suitability of major food crops in Ghana

chance that the impacts of climate change could be reduced through systematic planning for climate-adapted development. This is, to our best knowledge, the first study to assess the impacts of climate change on multiple crops quantitatively at this resolution for a whole country. Supporting information S1 Fig. Map showing the climatic division for north and south in Ghana. (TIF) S1 Table. Accuracy metrics for modelling maize, sorghum, groundnut and cassava suit- ability in Ghana under current climate conditions. (DOCX) S2 Table.
