Dürre refers to a prolonged period of abnormally low rainfall, leading to a shortage of water. It is a natural phenomenon that can occur in any climatic region. Droughts are typically characterized by their duration, intensity, and spatial extent. The impacts of drought can be widespread, affecting agriculture, water resources, ecosystems, and human health.

The causes of drought are complex and can be attributed to a combination of meteorological, hydrological, and atmospheric factors. Meteorological drought is defined by a lack of precipitation. Hydrological drought occurs when the available water in rivers, lakes, and reservoirs falls below normal levels. Agricultural drought impacts soil moisture and crop production. Socioeconomic drought is characterized by the imbalance between water supply and demand, leading to social and economic consequences.

Droughts can have severe consequences. In agriculture, reduced rainfall can lead to crop failure, livestock losses, and decreased food security. Water scarcity can affect drinking water supplies, sanitation, and industrial production. Ecosystems can suffer from reduced vegetation, increased risk of wildfires, and loss of biodiversity. Human health can be impacted by heat stress, malnutrition, and the spread of waterborne diseases.

Mitigation and adaptation strategies are crucial for managing drought risks. These include improving water management practices, promoting water conservation, developing drought-resistant crops, and implementing early warning systems. Understanding the causes and impacts of drought is essential for developing effective strategies to build resilience and minimize its adverse effects.
