What is the Meaning & Definition of drought
Considered one of environmental phenomena affecting the development of the human being and of all potential life forms, the drought can be described as the absence of irrigation or water on the ground or surface. Drought is usually caused by the lack of rain in a region, and while in some cases may have to do with the common cycle of events (i.e., in areas that are prone to drought), in others it can happen unexpectedly.
Drought can occur for several reasons, all of them linked to the absence of water. In this sense, some cases of drought may occur in the continued absence of precipitation which serve as natural irrigation for the Earth. In other cases may be due to the drastic reduction in watersheds of different sizes (usually basins of stagnant water such as lakes or lagoons, but also streams or small rivers can dry). In either case, drought appears onstage as a consequence of climate change that causes the increase in temperatures and the arbitrary redistribution of natural phenomena such as rain, while in a country hard will happen and extensive droughts also occur large and uncontrollable floods.
As stated at the beginning, the main problem of drought is that it presents significant difficulties for the normal development of life, either from plants, animals or human beings. Drought makes soils, in addition, to lose its nutrients, moisture, becoming impractical and unsuitable for agriculture or grazing, then further limiting the possibilities of survival. Uncontrollable and prolonged droughts can easily make a land before rich and fertile in a desert, a phenomenon known as desertification.
