Drought is not a mysterious phenomenon, but methods for dealing with it are still unknown to humans.

For thousands of years, our planet, civilizations, and humanity have been faced with phenomena that contribute to both their formation and development, and destruction. Echoes of cataclysms, natural disasters daily reach even the most comfortable areas of the Earth for living. One of these phenomena, characteristic of every era and overtaking hundreds of thousands of lives every minute, is drought. This is an indisputable fact.

Causes of drought

Drought is a natural phenomenon that is characterized by a prolonged absence of precipitation and a stably high air temperature, leading to the disappearance of plants, dehydration, hunger and the death of animals and people. The causes of such destructive natural processes were identified in the first half of the twentieth century. And global climate phenomena themselves were called El Niño and La Niña.

The phenomena, which were given such touching names, consist of a prolonged temperature anomaly, the interaction of air and water masses, which at intervals of 7-10 years make different parts of our planet literally shudder from abundance or lack of moisture.

Threats and consequences

In some areas of the Earth, hurricanes, tornadoes and floods rage, while others die from a lack of water. These terrible events with children's names, according to many scholars, destroyed powerful ancient civilizations, for example, the Olmecs; in the life of a number of peoples of the American continent they provoked the development of cannibalism, which captured the Indian tribes in dry years. Now the prolonged absence of rain and heat leads to mass deaths, mainly in Africa, destroying the lakes of South America, causing serious damage to the agricultural industry of the North American continent and Europe. Therefore, there is no doubt that drought is a reason for humanity to mobilize all its forces, knowledge and other resources in the fight against an incomprehensible, but very formidable, natural enemy.

Hot summer

Drought in Russia also remains relevant. Every year in the summer months in several regions, the Ministry of Emergencies introduces an emergency mode due to the stable high air temperature, coupled with an almost complete absence of precipitation, which sooner or later provokes fires in vast territories. The year 2010 was remembered by the Russians as a thick smokescreen that stretched for thousands of kilometers. At the same time, forest and peat fires raged in fifteen regions of the country , destroying settlements and infrastructure along with trees. Damage to the population and the state as a whole turned out to be colossal. Residents were suffocating from smoke, and insurance companies - from fabulous payments.

Crop yields, as well as dairy farming, which faced an acute shortage of feed, were under attack. It was in 2010 that the drought in Russia marked a new temperature record, set 70 years later from the time of such an abnormally hot summer.

Autumn Drought: A Threat to Winter

Often drought takes agriculture by surprise in the fall. It would seem that autumn is a period of rains, the first snow and temperatures that are relatively acceptable for plant life. However, precipitation that did not fall on time often affects the entire crop, the areas of which are large. That is why agricultural workers keep abreast even in the fall.

Problem of the whole world

Billions of losses, jumps in inflation, hunger, mass deaths of people and animals. All of these are the effects of drought. Every day, the news flickers about certain examples of abnormal heat without precipitation. So, in 2011, the inhabitants of China became victims of the drought. The flood that harmed more than three thousand people was replaced by an atypical, unbearable heat. The extreme drop in the water level in the Yangtze River made navigation difficult and, as a result, caused damage to many areas of activity. The failed rice crop created a crisis in the agricultural commodity market.

More recently, in December 2015, drought literally changed the geographical characteristics of an entire country - in Bolivia, one of the largest lakes, Poopo, was destroyed by continuous heat. Due to the fact that the locals previously existed only from fishing, in January 2016, a significant outflow of the population was observed in this region.

Climate change has had the most significant impact on the African continent. It is from there that alarming messages and calls for the collection of humanitarian aid come with frightening constancy . The difficult situation with rebels who deny the catastrophe and impede the transfer of food, further exacerbates the situation. Drought in Africa is a particularly ruthless phenomenon. The world community does not disregard what is happening, but from year to year a huge number of people die.

Despite the fact that mankind is making enormous steps towards its power, nature is not subject to it yet, and with its whims, sometimes very cruel, you only have to put up with it. Overtaking the continents one by one, drought confirms this.
