What is dry?

Drought is a climatic event marked by a prolonged period of reduced precipitation. In fact, drought is part of a natural climate cycle in many regions of the world, but they can still be very disturbing, especially if the impact of drought increases by human activity. The conditions of drought are interesting social, politically, economically and the environment, and at the moment several regions of the world often experience dry conditions. This may deepen to a hydrological situation in which the total water supply is low and conflicts may occur compared to water sources, in which case agricultural drought may also occur, such as an increase in average temperature or unusually high branches. Hot, dry weather to descend to desertification and can also lead to dust storms and fires. The arguments of natural sources can be very full under drought, such as when two nations go to war over a source of shared water on the border, or when people migrate in mass to find land that does not suffer from drought.

There may be a number of changes in the natural environment during drought. Algae tends to proliferate in water sources due to elevated temperatures and reduced water supply and eyelash flowers can choke fish species and animal diseases. The landscape can also change radically because plants, trees and shrubs die of water lack, and resistant opportunistic species move to feed on. This can also change the demography of animals in the natural environment, while the animal sensitive animals disappear along with fragile plants.

When the regions or nations suspect that drought conditions, often take steps to reduce the impact and raise awareness. For example, citizens may be asked to be more cautious about their use of water and can be taken to send measures in water from other locations to maintain stable water supplies. The appeal may also be made for international assistance in the form of water supplies, foodn to replace damaged crops and peacekeeping units to deal with the outbreak of violence over rare resources.

recovery may take some time, even if the rainfall begins to return to a normal level. Snowpack usually decreases radically and reduces the supply of stored water and the soil may require careful tendency to recover because the plants and animals are restored. Social chaos, which can cause strict drought, can also have long -term consequences.
