1. Lack of precipitation: The most common cause of drought is a prolonged period of below-average rainfall. This can be due to natural climate variability or weather patterns such as El Niño.

2. High temperatures: Hot temperatures can increase evaporation rates, leading to a depletion of soil moisture and water sources. This can exacerbate drought conditions.

3. Deforestation: Clearing forests for agriculture or development can disrupt local weather patterns and reduce the amount of moisture in the air, leading to drier conditions and increased risk of drought.

4. Overuse of water resources: Excessive extraction of groundwater or surface water for agriculture, industry, or domestic use can deplete water sources and contribute to drought conditions.

5. Climate change: Global warming is leading to changes in precipitation patterns and increasing the frequency and severity of droughts in many regions. Climate change can also exacerbate other factors such as high temperatures and water scarcity.

6. Land use changes: Urbanization, land degradation, and changes in land use practices can alter the natural water cycle and reduce the availability of water for plants and ecosystems, leading to drought conditions.

7. Natural disasters: Events such as wildfires, hurricanes, and volcanic eruptions can disrupt local ecosystems and water sources, leading to drought conditions in affected areas.

Natural Causes:

- Lack of precipitation: Prolonged periods of low rainfall or snowfall can create a moisture deficit in the soil and atmosphere.
- Increased evaporation: High temperatures, low humidity, and strong winds increase the rate of evaporation, removing moisture from the soil and vegetation.
- Vegetation removal: Deforestation and land clearing can reduce transpiration, which releases moisture into the atmosphere.
- Drought cycles: Certain regions experience naturally occurring drought cycles due to fluctuations in weather patterns and climate.

Human Activities:

- Overuse of water resources: Excessive water extraction for agriculture, industry, and domestic use can deplete water supplies and exacerbate drought conditions.
- Land degradation: Poor land management practices, such as overgrazing and soil erosion, can damage soil structure and reduce its ability to retain moisture.
- Climate change: Rising global temperatures and altered precipitation patterns can increase the frequency and severity of droughts.
- Urbanization: The expansion of impervious surfaces in cities reduces the amount of rainwater absorbed into the ground, contributing to urban droughts.

Other Factors:

- Altitude: Higher elevation areas tend to receive less precipitation, making them more prone to droughts.
- Geographical location: Regions located in dry or semi-arid climates are naturally more susceptible to droughts.
- Topography: Steep slopes and poor drainage systems can hinder water retention and exacerbate drought conditions.
