Warning of the risk of serious water shortage

Security Water resources and food security are topics that the United Nations (UN) offers for World Water Day (March 22) this year.

On this occasion, the UN warned the world risk of facing water shortages by 2050, when Earth's population is expected to increase by 2 billion to 9 billion.

In recent reports, the UN said that the world's water resources are now facing many challenges such as increased demand and climate change that make disasters worse.

Water scarcity is occurring in many areas and there are currently about 40% of people in areas where climate fluctuations are severely deprived of water.

The UN warns that about 20% of the world's population will face water shortages by 2050.

According to the UN, the main reason for that situation is history
Excessive use of water for food production.

Despite the Green Revolution in the 70-80s of the last century with the intensification of the use of chemicals for fertilizer and pesticides, as well as the application of irrigation schemes for irrigation . saved help many people get out of poverty, but also cause serious harm to the environment.

About 25% of the world's cultivated land is degraded, many large rivers are depleted at certain times of the year, the area of ​​rivers and lakes is narrowed.

In addition, the abuse of chemical fertilizers and pesticides also pollutes water sources, reduces the amount of water and at the same time threatens the environment and human activities.

To overcome these difficulties, environmental experts say the simplest way is to use the remaining water effectively.

According to the UN, assessing the productivity of the agricultural sector must take into account the efficiency of using inputs such as land, chemicals and water resources.

New technologies for irrigation should be developed to make water more efficient for agricultural production.

In addition, there should be water resource management policies to reduce the impact of water-related disasters.

The UN also introduced "conservation agriculture" measures to maintain the agricultural ecosystem to increase productivity and ensure sustainable development, increase income, and ensure food security while still protecting the environment. school and materials.

In addition, the UN also urged people around the world to actively protect forests, effectively use water resources, enhance the application of wastewater recycling technology and change diets to protect water resources for the future. .

In 1993, the UN General Assembly selected March 22 every year as World Water Day to highlight the role of water resources in people's lives, thereby increasing the awareness of planetary inhabitants about the situation. Water source and call for practical protective actions.
