Drought

Introduction: Drought is the most important factor limiting plant production in most agricultural areas of the world (Tas & Tas, 2007). During drought stress, inappropriate adjustment of photochemical system II and thermodynamic damage can disturb the flow of electrons and lead to the generation of free radicals. Oxidative damage is caused by incomplete detoxification of reactive oxygen species. Damage caused by oxidative stress includes enzyme inactivation, lipid peroxidation, proteolysis and DNA chain disruption, chlorophyll content and dye color reduction (Friso et al., 2004, Gechev et al., 2006; Baruah et al., 2009).

One of the biggest and most common effects of global climate change is drought. As the climate becomes warmer and the precipitation does not change, the possibility of drought will be greater. These droughts do not occur anywhere, but where it is, there is a possibility that it will be much more serious than before. ForestGEO has helped to discover that it is a bigger and older tree - those with the highest carbon content often suffer more when their local ecosystem is depleted. That's because it is more difficult to raise the water to a higher altitude. Crowns of big trees will also be higher and higher, so they will be affected by the high temperature of the sun, high wind speed and low humidity. Small trees are protected by surrounding trees

Droughts can have many devastating effects on communities and the surrounding environment. The extent of the damage depends on the strength of the drought and the period during which the area is considered under drought conditions. Drought will have a greater impact on the poorer communities than the more affluent communities and opportunities to introduce resources from other areas will increase. However, drought is extremely harsh for any type of community. The effect of drought on the community is the impact on water supply. Local governments or state governments will implement water restrictions if the drought situation remains unresolved or there is insufficient rainfall to mitigate the drought situation. This is important. The community needs to quantify the water consumption so that the water in the reservoirs and streams is not too low to meet the needs of utilities, other water users and local ecosystems.

Drought is a condition of unusually dry weather in geographical areas. Droughts are long-term rainfall and shortage of water in specific areas. During the drought, the amount of rain falls below normal, causing water imbalance and leading to water shortages. It occurs when evaporation and transpiration rates exceed precipitation over a relatively long period of time. Droughts should not be confused with dry climates such as the Sahara Desert and the Tar Desert. It is characterized by unusual water and food for humans and animals.
