The pressure on agricultural land increases not only due to the limited availability but also due to the deterioration of the quality of agricultural land. Soil erosion, waterlogging, salinisation and alkalinisation of land lead to land degradation. What happens if the land is consistently used without managing its fertility? The land is degraded and productivity declines.

Who has classified wastelands by using remote sensing techniques?

National Remote Sensing Centre

There are two processes that induce land degradation. These are natural and created by human beings. National Remote Sensing Centre (NRSC) has classified wastelands by using remote sensing techniques and it is possible to categorise these wastelands according to the processes that have created them.
