The Earth is about to lose 1/3 of its food land

Recent scientific studies show that if there are no timely interventions, humans may lose one-third of food land in the near future.

The area of ​​cultivated land in the world is seriously degraded

Soil is a valuable asset to produce food, absorb excess carbon and prevent erosion . but according to scientists' research, the surface soil is in danger of being partially lost in the future.

Farming land in the world is seriously declining.

The United Nations stipulates that 2015 is an international land year with a warning of 33% of the planet's land resources being degraded due to erosion, pollution, acidification and nutrient depletion (according to New Scientist). ). The main cause of this situation is due to the process of managing bad land of people. Unless we take timely measures, the land area per capita is only one quarter of 1960's by the end of this year.

In December this year, the United Nations will have an official report on the state of the world and the situation may be worse than the currently published figures. It is estimated that every minute we lose a cultivated area equivalent to 30 football fields and if we continue this momentum until 2075 we will almost no longer have land to cultivate.

Peter Groffman, a researcher at the Cary Institute of Ecosystem Studie, New York, said: "Many people think that land degradation is the biggest environmental threat to people ."

In addition to serving farming, the land is a solid wall against climate change. Bacteria and fungi in soil absorb carbon from plants and decomposed animal carcasses. According to Nature, soil can contain three times the amount of carbon compared to air.

Using synthetic fertilizers is one of the culprits causing soil erosion.

One of the culprits of soil erosion is the use of synthetic fertilizers that make soil acidic, salty and obstructing the activity of fungi, plant roots that help store carbon.

The United Nations believes that this can be improved by changing agricultural practices , shifting from monoculture to rotation and intensifying crops capable of replenishing soil nutrients.

You will be surprised to know that to form a 1cm thick layer of soil, it takes about 1000 years. Therefore, land resources for humans are extremely valuable and need to be planned for protection so that they can be used for a long time.
