According to the United Nations Environment Program, if 350 million hectares of degraded land are restored by 2030, it will generate $9 trillion-worth of benefits for the ecosystem and will get rid of almost 13-26 gigatons of carbon and toxic gases from the atmosphere. This shows the vast benefits of global land repairing that go beyond just planting trees to promoting a more sustainable way of using land and improving the soil quality. To this effect, land repairing projects have started all across the globe, especially in areas like Brisbane and the Coast in Queensland, Australia.
One major example of such a land repairing project is the Losseau Plateau in China where there was widespread degradation and deforestation of the hillscapes until the mid-1990s. After the mid 90s, the Chinese government created a land repairing project which completely restored the landscape and helped create lush green vegetation areas. This topsoil was rich in nutrients and produced healthier food and retained carbon underground to prevent toxic gases in the environment. The biggest benefit of this project was how well the waterways have reappeared due to good soil percolation and moisture retention that have also created a hospitable environment for wildlife and mammals.

Helping improve the global land quality and promoting more productive ecological systems
Land repairing can also take place right at the grassroots level in small scale projects that start right from the corners of your home. In urban areas, planting trees and shrubs on sidewalks can help prevent flooding and keep the soil tight. Planting green trees and plants on urban terraces of your home can also help filtrate water before it goes in the storm drain and thus reduce pollutants. This green cover will also help remove carbon dioxide from the air and promote a cooler environment in cities. Lastly, converting small brown farmlands into green urban gardens that feed local populations can help preserve nature.
Preserving lands and open areas can make people more aware of being responsible for the environment and work towards it.
More people will adopt practices to conserve the environment and prvent deforestation and over-cultivation of land.
Preserving the land will also help promote eco-tourism that will benefit the locals and help improve the economy.
As part of global land repairing it is important to note that we must restore agricultural land and make it more productive and healthy by using a variety of sustainable farming techniques. These practices include leaving crop residues on lands to prevent erosion, growing intermediate crops between harvest seasons to retain nutrients and to rotate crops by planting different varieties so that pests and insects do not start attacking the land where similar crops are constantly grown. There is also another way to restore agricultural land by growing cover crops that bloom close to the trees and shrubs and help provide protection to the soil and improve its overall quality by regulating the soil heat and temperature.
Once I learnt to restore my local farms, I noticed a massive increase in healthier output and good quality soil
I enjoy farming and was amazed at how small changes like using organic manure could impact my topsoil and produce.
The quality of the local waterways in my area have become much better with the growth of vegetation cover all around.
