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

marginally suitable for the four crops will increase from 1% (1689 km2) under current climate to 3% (7770 km2 RCP2.6) or 1% (3040 km2 for RCP8.5) of the country. Similarly, the areas that are marginal for two of the four crops will increase from 9% (21958 km2) under current Fig 3.
