Drought in the Sahel

High Pressure Air Systems High pressure air systems cause droughts due to the lack of rain. In the high pressure air systems air is pressing down therefore no air can evaporate resulting in no rainfall. An example of a high pressure weather system is the Sahel. The Sahel is a mainly flat, belt of land lying between the Sudanian savannah and the Sahara desert. The high pressure causes many major impacts, like droughts which will lead to crop failure and lack of drinking water which will lead to famine and ultimately course death. Another issue surrounding high pressure in the Sahel is flooding. The flooding occurs after a long period of time without rain when the soil has fully dried out and has developed a solid crust on the surface to which the precipitation can not penetrate. This flooding causes additional problems because the water has no where to go because as previously stated with the land being relatively flat the water has no where to run and hangs around because the high pressure means there is no evaporation. These effect people differently like children are a lot more susceptible to malnutrition and starvation because they need more nutrients. It doesn’t just affect people living in the areas affected by drought because the people who flea the Sahel go to the surrounding countries who have problems because suddenly there is a lot more demand for essential things in life due to an increase in population. There would be a bigger demand for things like homes, food and electricity. The increase in demand for electricity would mean more fossil fuels being burned thus polluting the atmosphere more and contributing to global warming therefore heat the Sahel even
