Drought and limited water sources, where low rainfall and tyrooms, if they occur, will increase water shortages, reducing the chances of rainfall when it occurs to feed the underwater reservoir. Higher temperatures and increased rates of evaporation and vitus will increase the need for plant irrigation and demand for water, thus increasing pressure on this already scarce source.
In the Gaza Strip, water will be worse, where water is more demanding than other areas, but higher demand for water and doubling water shortages will accelerate the entry of sea water into the underwater tank and predict a much faster decline in the quality of water in Gaza than expected. It should also be noted that the high incidence of heavy rainfall increases the likelihood of flooding, especially in crowded cities with modest rainwater drainage systems.
Heat shifts, however, are particularly dangerous to the health and safety of patients, the elderly and children, especially when they coincide with weak electricity and long hours of interruption, as in the Gaza Strip.
Local vulnerability to global climate change is rapidly rising at sea level and regional rainfall patterns. One of the most significant effects expected in Palestine-Israel in the current century is the decline in rainfall, accompanied by a marked rise in temperatures. This combination of low rainfall and high temperature will result in increased demand for water (a resource that is already underutilized) and whose supply will continue to decline beyond demand and could lead to water insecurity. Agriculture, which is an essential component of the economy of the Occupied Palestinian Territory, will also suffer.
