The meteorological drought in Hunan continues. What impact will this natural disaster bring to the local area?

Drought has led to the failure of all crops planted locally, and affected people's normal domestic water consumption and the destruction of the ecological environment.

What are the hazards of drought?

Reducing people's immunity leads to the reduction, limitation or even suspension of production in agriculture and animal husbandry, and the price of food crops rises; As a result, the water level of urban residents is lowered, and it is difficult for people and animals to drink water; The water level of lakes and rivers is reduced, and some of them are dry and cut off, which endangers river transportation and leads to difficulties in shipping industry; Climate drought will aggravate the process of land desertification, destroy the green ecological environment and cause other floods. The most intuitive harm of drought is to reduce the quality and yield limit of food crops and reduce the output of agriculture and animal husbandry. For example, early rice continues to ripen at high temperature, which leads to an increase in empty shell rate, cracking of some rice fields and backflow of seedlings. Drought of dryland crops is obvious, such as peanut kernel withering, and navel orange leaves in Gannan are yellow and curly.

In the severe drought, people have difficulty drinking water and their lives are threatened. Drought will lead to the reduction of water, electricity and energy shortage, which will seriously endanger economic and social development and people's lives. In the dry season, fire accidents are easy to happen and cannot be controlled and put out. Most fire accidents, especially large forest fires, occur in the dry season. Drought also often produces locusts.

What caused the drought?

Due to climatic reasons, meteorological factors such as long-term no precipitation or too little precipitation are important factors leading to drought. Geological structure causes and geological structure standards are one of the causes of regional drought. The water source standard and drought resistance are insufficient, and drought is also closely related to the poor water source conditions caused by insufficient water conservancy and hydropower engineering equipment, such as water conservancy engineering equipment and deep wells. Due to the steady growth of population, the development of local social economy, and the continuous growth of life, production and water use, water resources in some areas are over-exploited and exceed the carrying capacity of local water resources. The rational utilization rate of water resources is low, because there is usually more precipitation and less precipitation in southwest China. The efficient utilization rate of water for agriculture, animal husbandry, industrial production and domestic use is significantly different from that in China's long-term water shortage areas, which matches the drought.
