Answer:
Explanation:Human activities can trigger droughts in several ways, including:
1. Deforestation: Trees play a critical role in the water cycle by absorbing and releasing water into the atmosphere through transpiration. Deforestation reduces the number of trees, which can lead to reduced rainfall and the occurrence of droughts.
2. Land-use changes: Changes in land use, such as urbanization, agriculture, and mining, can alter the hydrological cycle and lead to reduced water availability. For example, urbanization can lead to increased runoff and reduced infiltration, which can result in reduced groundwater recharge and decreased soil moisture, leading to droughts.
3. Overuse of water resources: Overuse of groundwater and surface water resources for agricultural and industrial purposes can lead to reduced water availability, especially during dry seasons, leading to droughts.
4. Climate change: Human-induced climate change is causing changes in global climate patterns, including increased temperatures, changes in precipitation patterns, and more frequent and severe extreme weather events, which can lead to droughts in some regions.
Overall, human activities can disrupt the natural water cycle, leading to water scarcity and droughts. It is important to manage water resources sustainably and reduce greenhouse gas emissions to mitigate the impacts of human-induced climate change on the occurrence of droughts.
