Step-by-step explanation:
Droughts can be caused by natural causes such as weather patterns. But they are increasingly caused by human activities. Such activities include:
i. Climate change: Global warming makes extreme weather more likely. It may make places drier by increasing the evaporation. When land becomes very dry, an impermeable (not allowing fluid to pass) crust forms, so when it rains, water runs off the surface, meaning sometimes flash flooding occurs.
ii. Deforestation: Plants and trees release water into the atmosphere, which creates clouds and thus causes rain. Bad agricultural practices like intense farming not only contribute deforestation but also affects the soil quality, making it dry much quicker.
iii. High water demand: There are several reasons water demand outspam the supply, including intensive agriculture and population growth. Also, high demand upstream in rivers can cause drought in lower, downstream areas.
