Monitoring of resource utilisation

Continuous recording of the changes in the quality and quantity of various.resources  is as imyortant an element of resource planning as evaluation of original reserves.  The monitoring of resource utilisation is best done through remote sensing. It involves studying the nature and size of reduction or deterioration of the forests, soil, land, mineral deposits, water Wits  rind  snowpacks.  For example monitaring of river will help us in averting or reducing the menace of  tloods and erosion. Monitoring has also demonstrated that over-imgation of arid or semi-arid areas causes salinity or alkalinity of the soil.
