Lands as a resource is now under serious pressure due to an increasing'Land humger'to produce sufficient quantities of food for an exploding human population.It is also affected by degradation due to misuse.Land and water resources are also polluted by industrial waste and rural and urban sewage apart from being diverted for short-term economic gains to agricultur and other purposes and semi-arid land is being irrigated and over used.
The most damaging change in landuse is demonstrated by the rapidity with which forests have vanished during recent times,both in india and in the rest of world.Forests provide us with a variety of services .These include processes such as maintaining oxygen levels in the atmosphere removing carbon dioxide,controlling water regims and slowing down erosion as well as producing food,fuel shor term gains produced by converting forested lands to other uses.
