The Droughts | it causes, effects and ways to reduce it

Subject: Drought has become a chronic phenomenon. What are the ways to reduce its effects?

Drought has become in recent years a major problem that haunts humanity and worries officials in many countries of the world, as drought is no longer as in the past just an occasional condition that appears from one period to another, but has become a chronic phenomenon that humans should adapt to and take into account in all food and development policies in general. But is there a way to reduce its effects if its causes cannot be addressed?

Causes and effects of drought

The scourge of drought is no longer confined to some parts of the globe and not others, as was the case in a few countries such as the Sahel countries in Africa, it affects various countries, including those that were known for their abundance of water and abundant rainfall. A country like Australia, one of the largest cereal producers, has suffered in recent years from a severe drought that has resulted in crop shortages and skyrocketing world cereal prices, resulting in Social and political unrest in many countries, especially the poorest ones.

Scientists and researchers attribute this phenomenon to various factors. Perhaps the most important of these reasons is the major climatic imbalances that the planet has been witnessing for decades due to pollution, global warming, desertification, shrinking forest areas, depletion of water brushes and melting icebergs in the Arctic. This is in addition to the erratic rainfall, which often takes the form of strong storms that result in severe floods that erode the soil and damage agricultural crops. On the other hand, there is the pollution factor: toxic chemicals emitted from factory chimneys, car exhaust and other waste contaminate the water, making it undrinkable and unusable for irrigation. Moreover, the exponential demographic growth and steady development of industrial and agricultural activity that the world has witnessed since the end of the Second World War are increasing the pressure on water resources, leading to their shrinking and erosion. For years, scientists have been sounding the alarm and warning of a real catastrophe.

The drought dilemma poses a real threat to humanity and threatens millions with death from thirst and starvation, and most of all, future wars between the countries of the globe will be fought because of the conflict over water sources. The inhabitants of the valleys in particular, as well as the inhabitants of some cities, are suffering from a lack of this vital material, which has become known as blue gold due to its great value. Villagers have to walk kilometers to get something to quench their thirst. Because of the drought, many migrated their villages and towns after abandoning their agricultural activity and headed towards Major cities where they are crowded in marginal neighborhoods that do not meet the conditions for a decent living. It is alsothe case in many countries, such as the African Sahel countries, where thousands of people die every year from thirst and hunger. Indeed, rich and technologically advanced countries are beginning to fear desertification and water scarcity.

But is drought inevitable and helpless in the face of its devastating effects? Are there no solutions to reduce its effects if its causes cannot be addressed?

 

Effective solutions to reduce the effects of drought

The scientific research carried out by scientists in many institutes and scientific research centers around the world almost unanimously agrees that the causes and causes of drought are human, not climatic and natural. While some do not exclude the natural factor as a drought trigger, the main factor remains human activity on earth, so effective solutions to the phenomenon of drought remain possible and possible. Indeed, most, if not all, scientists, but even politicians, heads of state and UN officials agree on the need to reduce the scourge of pollution and work to solve the dilemma of global warming. In this regard, many conferences have been held to examine possible solutions, from the Rio de Janeiro summit held in Brazil in 1992 to the Kyoto summit in Japan in 1997, governmental and non-governmental conferences have been held and engaged in the search for the reservoirs of the disease and ways of treatment. Indeed, the issue of drought and pollution has become strongly present in the G8 summits, which are dominated by issues of a political and economic nature. Due to its extreme importance, the environment has become an essential component of state policies, with ministries allocated to it, as in Morocco.

In order to reduce the phenomenon of water, air, and environmental pollution, many countries have begun to treat wastewater and wastewater from residential complexes and factories before it flows into the seas and rivers. It has also begun to seriously consider ways to reduce the amount of carbon dioxide emitted from factory chimneys and car exhaust. In this context, scientific research centers have devoted their efforts to replacing traditional polluting energy sources with renewable and less polluting alternative energies such as nuclear, solar and wind energy.

Awareness of the need to repair what has been corrupted by human hands in nature has grown. Governments and organizations have thus embarked on planting trees and allocating large areas to create new forests in order to preserve the environment and limit the encroachment of desertification, soil erosion and the exacerbation of the scourge of carbon dioxide, which is responsible for the ozone hole and global warming. International, regional and national associations, organizations and bodies such as Green Peace have come into being. International, regional and national associations, organizations and bodies such as Green Peace have come into being. It is concerned with protecting the environment and working to purify the water of the seas and rivers from pollutants and spread awareness among the people, and even in the agricultural field, efforts have focused on developing new plants and soils that do not require much water.

However, the most important thing that must be done in the medium and long term is to raise awareness among people of the importance of the environment and water and the need to preserve them for the continuation of life. The closest way to achieving this goal is through education and information: Governments must enact education policies that devote considerable space in their educational programmes to sensitizing pupils and students to the dangers to humanity posed by water scarcity and low rainfall, and urging them to avoid the causes of such a catastrophic situation. The same awareness-raising role must be played by political parties and the media. Water consumption must be rationalized, and wastewater must be disinfected for reuse.

The bottom line is that drought is not inevitable, but an inevitable consequence of human activity on the globe. Agriculture, industry and massive demographic growth put great pressure on water resources and lead to the depletion of this vital material. In order to reduce its effects, it is necessary to be aware of its risks, identify its causes and then work to address them, especially by fighting pollution and global warming, searching for alternative energies, constructing dams, and rationalizing water consumption.
