Vulnerability and policy relevance to drought in the semi-arid tropics of Asia – A retrospective analysis

Amidst all natural disasters, droughts are affected by the greatest number of devastating influences in the world. Drought brings various socio-economic impacts such as failure of harvest, unemployment, decrease in assets, decrease in income, malnutrition, decreased absorption of risk, thereby increasing community vulnerability. This white paper outlines existing methods focusing on vulnerability and assistance in assessing impact assessment to identify and identify regions, sectors, and communities currently in danger of drought. It also discusses the limitations, constraints and prerequisites of these methods, and with reference to recent research by the International Crops Association, the importance of micro-level information to demonstrate a more realistic understanding of impacts and vulnerabilities To emphasize. . Semi-arid tropical region (ICRISAT) This work provides a framework that provides guidelines for developing action plans to improve the resilience of vulnerable groups.

West Asia is mainly a dry semi-arid area and may suffer from drought, but there are also vast forests and fertile valleys. This area has grasslands, meadows, deserts, and mountains. Water shortages are a problem in many parts of Western Asia, with the population rapidly increasing and the demand for water increasing, salt watering and pollution threaten the supply of water. Major rivers such as the Tigris and the Euphrates River will be a source of irrigation water.

Several semi - arid areas in the world are in desert at an alarming rate. This process, called desertification, is not caused by drought but is usually the result of a human settlement in a semi-arid area for cultivation of crops and grazing of animals. The impact of domestic hooves on the soil may degrade soil and promote erosion of wind and water

Desertification is an environmental process of ecological degradation in arid and semi-arid areas and is often caused by human activity. Desertification by drought is a common misunderstanding. Drought in arid and semi-arid areas is common. Once rain returns, well-managed land can recover from drought. Soil management tools include maintaining soil nutrients and organic matter content, reducing cultivation, and improving coverage. These methods help to suppress erosion and maintain productivity while moisture is available. However, continuing abusing the land during the drought may increase land degradation. Increase in population and livestock pressure to remote areas promotes desertification
