WHAT HAPPENS IT DOES NOT RAIN FOR LONG PERIOD
Sometimes so happens that does not rain in region for a year or more. This leads shortage of water that region causing everywhere. environment drought. So, can say that if does not rain in region for long time causes drought sookha). Drought is period without rains leading to severe shortage of water in the region. happens follows.
The soil in the fields is normally moist because it has water in it. The soil continues to lose water by rporation and transpiration. The water lost by soil is usually made up by rains. If, however, it does not rain at all (or the rainfall is very low) for a long period, the o of water from the soil is not made up and hence the soil becomes dry (see Figure 14). Due to lack of rains, the water level in the lakes and ponds also goes down and some of them may even dry up completely. In the absence of rains, no water seeps into the ground and hence the level of groundwater in wells, etc., falls drastically. Due to this the groundwater also becomes scarce. In this way, a prolonged period of no rains (or very low rains) causes all round shortage of water leading to drought. Thus, the lack of rains for long periods may cause drought.
This picture shows the extremely dry cracked set in a field camed by the lack of rains.
The people living in areas having drought conditions face many difficulties in leading a normal life. Some of the ove long period problems faced by the people because of drought in an area are as follows:
In drought conditions, the soil does not have sufficient moisture (or water) to grow crops well. Since the crop plants do not grow well, drought leads to severe shortage of food for the people in that region. (ii) In drought conditions, the vegetation such as grass and other fodder does not grow well and leads to shortage of fodder for the domestic animals (like cows and buffaloes). () Due to shortage of food and fodder, many people living in drought affected areas even migrate to other places alongwith their domestic animals in search of food and fodder. Some people and domestic animals may even die of starvation.
