Question

how can droughts be triggered by human activities​

Answer 1

$\sf \: Answer$

Human activities that can help trigger droughts include: Widespread cutting down of trees for fuel - This reduces the soil's ability to hold water - drying out the ground, triggering desertification and leading to drought.

Answer 2

Drought can be triggered by human activities. One of the major reasons is deforestation.

• Human activities have reduced the amount of rainfall as the consumption of water is much more than the availability for later use by plants and animals.
• Deforestation is one major reason for droughts. Cutting down trees results in less water evaporation which reduces the number of clouds formed.
• Another reason for drought is soil degradation which is caused by intensive farming which results in soil losing its structure and texture losing its capacity to hold water.
• Increased demand for water is another reason. The rising population demands more water which causes a lack of water.

To improve the condition of drought people should consider water conservation, this is the least done by humans for nature.
