CISCE: Class 12

Key Points: Land Degradation

  1. Land degradation
    Land degradation is the general wearing away and loss of productivity of land due to factors such as salinization, erosion, deforestation, flooding, water-logging and unplanned urbanization.
  2. Importance of top soil
    The fertile top soil (15–20 cm thick) contains essential plant nutrients, and its degradation directly reduces agricultural productivity.
  3. Soil salinization
    Soil salinization is caused by the accumulation of soluble salts (mainly sodium, calcium and magnesium salts) which adversely affect soil structure and crop yield.
  4. Causes of salinization
    Salinization occurs due to inadequate leaching in semi-arid regions, rising and fluctuating groundwater table, rapid evaporation, saline irrigation water, canal seepage and seawater intrusion in coastal areas.
  5. Extent and impact in India
    About 7 million hectares of land in India are salt-affected, especially in coastal, arid, semi-arid and Indo-Gangetic regions, posing a serious threat to sustainable agriculture.

A Case Study

Jhabua district is located in the westernmost agro-climatic zone in Madhya Pradesh. It is, in fact, one of the five most backward districts of the country. It is characterised by high concentration of tribal population (mostly Bhils). The people suffer due to poverty which has been accentuated by the high rate of resource degradation, both forest and land. The watershed management programmes funded by both the ministries of “Rural Development” and “Agriculture”, Government of India, have been successfully implemented in Jhabua district which has gone a long way in preventing land degradation and improving soil quality. Watershed Management Programmes acknowledge the linkage between land, water and vegetation and attempts to improve livelihoods of people through natural resource management and community participation. In the past five years, the programmes funded by the Ministry of Rural Development alone (implemented by Rajiv Gandhi Mission for Watershed Management) has treated 20 percent of the total area under Jhabua district.

The Petlawad Development block of Jhabua is located in the northermost part of the district and represents an interesting and successful case of Government-NGO partnership and community participation in managing watershed programmes. The Bhils in Petlawad Development block, for example, (Sat Rundi hamlet of Karravat village) through their own efforts, have revitalized large parts of common property resources. Each household planted and maintained one tree on the common property.

They also have planted fodder grass on the pasture land and adopted social-fencing of these land for at least two years. Even after that, they say, there would be no open grazing on these lands, but stall feeding of cattle, and they are thus confident that the pastures they have developed would sustain their cattle in future.

An interesting aspect this experience is that before the community embarked upon the process of management of the pasture, there was encroachment on this land by a villager from an adjoining village. The villagers called the tehsildar to ascertain the rights of the common land. The ensuing conflict was tackled by the villagers by offering to make the defaulter encroaching on the CPR a member of their user group and sharing the benefits of greening the common lands/pastures.

How did the Bhils, through their own efforts revitalise the common property resources? Choose the correct option.
