The article describes the development and eco-restoration efforts in 72 ha of Rammadhi watershed, at Jhansi, Uttar Pradesh, India as an example of productive utilization of non-arable degraded lands. Increasing area under degraded lands in India has attracted the attention of scientists and the policy makers during the past 20 years with the creation of the National Wasteland Development Board. Land degradation was recognized as a major challenge affecting land productivity and livelihood, and efforts have been made to arrest it. Watershed management is considered to be the most viable tool for repair of such degraded lands so that they are restored to their normal production potential maintaining the natural resource base. This has been used as a tool for developing and managing the land resource at the Indian Grassland and Fodder Research Institute, Jhansi. Worldwide about 1.96 million hectares land are affected by human-induced soil degradation, mainly caused by water and wind erosion. The degradation of natural resources in India is equally grim among the Asian countries. In India out of a total geographical area of 329 million hectares, 70 percent of cultivated land falls under the rain-fed areas. Most of the arid and semi-arid regions have high concentrations of eroded and degraded natural resources. Excessive biotic and abiotic interferences have caused considerable degradation of the natural resources of land, water, vegetation and ground water aquifers. |
