Answer:
1. The first stage includes surveying, mapping and measurement of characteristics and properties of resources. The second stage examines resources from the points of view of technology, economy and need. The third stage is related to action-oriented planning which emphasises use and reuse of the sources.
2. Land use data is not available for whole country because the land use reporting is not done completely in the north-eastern states and some areas of Jammu and Kashmir has not been surveyed.
3.Land under permanent pasture is decreasing because, due to increase of population in an uncontrollable rate, demand for food, land for houses etc. are increasing. So, people start using the pastural ground for making their house or using it as an agricultural land.
4.The sown area that is considered only once is the net sown areas like Punjab and Haryana are major areas of 90% while Arunachal Pradesh, Mizoram, Manipur and the “Andaman and Nicobar Islands” holds the balance of less than 10%.
5.barren or uncultivated land a desert wasteland. 2 : an ugly often devastated or barely inhabitable place or area. 3 : something (such as a way of life) that is spiritually and emotionally arid and unsatisfying.
6.Soil degradation; which causes decline in soil’s productivity, deterioration in vegetative cover, qualitative and
quantitative decline of soil and water resources and pollution of air; is rampant in India. In recent decades, it is greatly aggravated
because of country’s increasing population, requiring marginal areas to be brought under the cultivation to meet the growing food
demand. Poverty and natural resources degradation coerces individuals to search for more land for food, fodder and fibre
production. The main causes of degradation due to direct/indirect human intervention are deforestation and removal of natural
vegetation, overgrazing, converting forests to farms, cultivating steep slopes and degrading marginal lands, other agriculture-
related activities and over exploitation of the vegetation for domestic purpose. Similarly, the removal or in-situ burning of crop
residues, no or least addition of organic manures, and intensive cultivation are the major reasons for the depletion of soil organic
carbon. Major threats to the conservation of soil resources are soil erosion both by water and air, salinization/alkalinity, acidity,
organic carbon losses, nutrient imbalance, pollution/contamination by toxic substances, and soil sealing and capping. Urgent
measures are required to arrest the degradation process and to restore productivity of degraded soils so that more food could be
produced to provide livelihood and environmental security to the increasing Indian population. This requires the systematic
knowledge on the soils, characterization of basic resources like soil, water, climate and biodiversity problems and potentials for
optimizing land use.
