In general, climate change is likely to adversely impact the agricultural economies of countries in Northern Africa. This impact can come from a number of sources.
The most obvious danger to agriculture is from lack of water. There is likely to be a lack of water in North Africa due to the changing climate. This will obviously have a major impact on agriculture.
It is also projected that climate change will lead to increased flooding. This is because the rains, though less overall, may be more intense when they do come. Since agriculture needs predictable and not very intense rains, this is a danger to agriculture as well.
If these adverse impacts occur, North African countries will need to import more food. This may well lead to higher prices for food in these countries. Higher food prices are likely to lead, in turn, to social unrest.
The impact of climate change on the agricultural economies of North Africa is likely to be severely negative if current projections hold true.
