What is essentially a wasteland?
Accelerating growth of wastelands/degraded lands created a buzz to the Government. The growing concern to prevent this extraordinary growth, Government of India have set up the National Wastelands Development Board in 1985 under the Ministry of Environment & Forests.
Categories of wasteland for Identification
Culturable Wasteland- The land which is has potential for the development of vegetative cover and is not being used due to different constraints of varying degrees, such as erosion, water logging, salinity etc.
Unculturable Wasteland– The land that cannot be developed for vegetative cover, for instance the barren rocky areas and snow covered glacier areas.
Categories of wasteland for Identification (Based on causative agents);
|Sheet Erosion||Sand Dunes||Mine Spoils||Land Slides|
|Rill Erosion||Sand Bar||Shifting Cultivation||Shallow Soils|
|Gully Erosion||Coastal||Industrial Wasteland|

The trick to solve any problem is to first have a reliable data set; the problem of wastelands can be addressed only if there is concrete baseline data that can be used for analysis. The data collected can be Climatic (rainfall, temperature, wind velocity,); Topography (angle of slope, length of slope); Erosion (the extent and intensity of erosion); Soil Properties (physical and chemical).
There is a need for site-matched technology to make the soil productive at a rapid rate because in nature the changes that occur rapidly take 200 – 400 years to attain equilibrium.
The method used for improvement for wasteland will depend on the type of wasteland. Some traditional methods can be the in-situ conservation methods for improving the moisture content of soil (bunding, terracing etc.); to promote natural regeneration; water harvesting; promoting agro- forestry.
