Land utilization forest, uncultivated, fallow, net sown area & oter uncultivated land 2, Land use pattern-forest area lower than 33%,permanent posture has decreased, net sown area varied 3. Land degradation & conservation measures - Afforestation, stablization of sand dunes, management of waste land, control of mining


  4. LAND UTILISATION Land resouces in india are used for several purposes, such as wasteland-A part of the land that is not utilized for the moment is classified as wasteland Fallow land-Cultivated land that is not seeded for one or more growing seasons Forest Lands-Forests safeguard not only water but soil as well.
