three reasons responsible for water scarcity in india
Water security The most common threat to water security is water scarcity. There can be several causes to water scarcity including low rainfall, climate change,[14] high population density, and overallocation of a water source. An example of periodic water scarcity in the United States is droughts in California. Another category of threats to water security is environmental threats.[15] These include contaminates such as biohazards (biological substances that can harm humans), climate change and natural disasters. Contaminants can enter a water source naturally through flooding. Contaminants can also be a problem if a population switches their water supply from surface water to groundwater. Natural disasters such as hurricanes, earthquakes, and wildfires can damage man-made structures such as dams and fill waterways with debris. Other threats to water security include terrorism and radiation due to a nuclear accident.[16]
Water politics in the Middle East Water politics plays a role in various areas of politics in the Middle East, and it is particularly important in one of the defining features of the region's political landscape. Water issues reflect a central aspect of the nature of the Israeli–Palestinian conflict; namely, the original influx of an additional large population mass to a relatively fragile geographical area of land, and the massive expansion of previously existing populations. Concerns over water have significantly helped to shape the Middle East's political development.[citation needed]
