Land restoration is the ecological process of bringing previously degraded land back into use for humans and wildlife and does not harm the surrounding ecosystems. This process helps restore ecosystems, feeds the growing global population, prevents erosion and prevents flooding and droughts. Here are six ways land restoration can be done across the globe to improve the quality of land:
Planting trees in lands without any vegetation cover or in areas where massive deforestation has taken place will help protect the topsoil, trap carbon and will also form biomass to improve the nutritional quality and organic material of the soil.
Allowing the controlled grazing of grasslands and pastures by bovine animals like cattle and bison to promote the healthy growth of topsoil and organic matter as the roaming can help preserve the soil and create good quality topsoil.
Conscious effort to rebuild and restore floodplain areas across the globe and prevent runoff from agricultural areas so that these lands can be made productive and can help improve water quality and prevent flooding and droughts in the future.
Planting a variety of crops in rotation on the same soil will help prevent the buildup of pests and pathogens that can happen when one crop variety is grown in one area and this will also help preserve the soil’s nutrients.
In cover-cropping, a series of crops like sugarcane and sweet potatoes are grown in lands after the harvest season to help prevent erosion of the topsoil as there is a huge gap between the harvest and the next crop-growing cycle.
In agroforestry, farmers can grow trees and shrubs along rotating crops in their farmlands to help improve soil health and retain carbon in the soil and also add to the crop yield of the farms by making it more productive.
Degraded land can be restored via the above practices but it is also necessary to recognise the cause of the land degradation, stabilise the site, reconstruct the land and monitor the area to ensure the land is properly restored and there is rich and productive soil growing there.
