agriculture review

Drought is one of the most significant environmental challenges that farmers & agricultural producers face. It can lead to crop failure, reduced yields, etc.
It is a phenomenon that occurs when there is a deficient supply of moisture in a region due to sub-normal, infrequent distribution of rainfall.
When the amount of rainfall received in a season is less than 25% of its long-term average value, it is considered a meteorological drought.
It refers to a scarcity of surface and sub-surface water supplies that leads to a shortage of water for normal & specific needs.
If there is 4 consequetive weeks of severe draught having rainfall scarcity of more than 50% of the long term average, then it is agricultural draught.
According to NASA, global surface temperatures have risen by about 1 degree Celsius since the late 19th century. This led to increase in draught occurence.
When trees are cut down, the amount of moisture in the soil decreases, leading to a reduction in rainfall. It lead to increase in draught occurence.
Human activities, such as agriculture, industry, and urbanization, require vast amounts of water, which can lead to depletion of water resources.
