Semi Arid climate zones are usually found between deserts and rainforests. Some areas with semi-arid regions are Northern and Southern Africa, the Middle East, Central Asia, Western North America, Southwestern South America, and Australia's interior. Peveril Meigs the Third (1903-1979) mapped the semi-arid and arid areas of the world in the early 1950s for UNESCO and his maps were have been extensively used since then.
Middle East and Asia: The Middle East and Asia are largely an arid and semi-arid land. The region stretches from Turkey (west) to Kazakstan (east) and from Yemen (south) to Kazakstan (north).Grasslands, livestock, and water resources are the most liable to cliate changes. The water shortages are already a big problem in these regions, and shortages would increase with a climate change. The land deterioration and small water supply limit agricultrural production and threaten food security for the people. This could impact the peoples health in the territory.
Australia: This district goes from the tropics to the mid-latitudes; the climate is affected by the oceanic environment and the ENSO phenomenon. In the long term, it could alter the soil, plants, ecosystems, and it could potentially cause more insect outbreaks. It could possibly cause changes in food production, which could affect the cost of some goods, which, in turn, could cause major economic impacts to Ausralia. These changes would mainly effect the indigenous communities and economically dissadvantaged people.
North America: The structure of the semi arid America has been changing a lot over the last hundred years. Some indigenous species have been becoming back to the region recently. these species are shrub and brush species that haven't normally been present. The grasslands are getting bigger every year. One-third of North America is considered to be arid and semi-arid.
South America: More than 25% of South America is arid or semi-arid. They have lacking water supplies in the areas. Mining is a very big economic areas in these countries. Mining brings in a lot of their money, but also destroys the communities. The water availability on the west coast varies, so it could go from subtropical semi arid to moist mid-latitude climates.
