Answer:
Human activities can trigger droughts in several ways:
Deforestation: Deforestation can lead to droughts by reducing the amount of moisture retained in the soil. Trees absorb water from the soil and release it into the atmosphere through a process called transpiration. When trees are cut down, there is less transpiration, leading to a decrease in rainfall and an increase in evaporation.
Agricultural practices: Some agricultural practices can also contribute to droughts. Overuse of irrigation can deplete groundwater resources, reducing the amount of water available for other uses. In addition, overgrazing can lead to soil erosion, reducing the soil's ability to hold water.
Urbanization: Urbanization can also contribute to droughts. As cities grow, they use more water for landscaping and drinking . These decrease the amount of water available for other uses, including agriculture and industry.
Climate change: Climate change caused by human activities can also contribute to droughts. Warmer temperatures can increase evaporation, decreasing the available moisture. In addition, changes in rainfall patterns can lead to more frequent and severe droughts in some areas.
