The economic impact of climate change on farm decisions and food consumption in Ghana por Etwire, P.M.

“…A simulation of the effects of climate change shows that crop farmers will likely adapt VII by replacing high-value crops with millet, a low-value but climate-resilient crop. All things being equal, the results of our first two studies imply a decline in the aggregate value of agricultural output, hence there is the need to invest in research that seeks to improve the climate resilience of high-value food-crops and tree-based farms. …”
