Suggestion for Improvement

It may be noted that out of the total area of wastelands in the state, about 880 sq km has been treated and reclaimed by the government and this constitutes only 12% of the wasteland in the states and hence the major areas are yet to be reclaimed. Besides the efforts taken up by the Government a joint co-operative effort from the public, NGOs and organizations and remedial measures is called for some suggestions may be helpful towards implanting measures for reclamation of the wastelands in the states.

  • (i) Measures for the effective massive planting of trees in the forest areas with the right and appropriate selection of tree species.
  • (ii) Planting of sand binge species of sedges shrubs etc. on the naked hill slopes whish are exposed to wind direction. Some species like Pennisetum, Chrysopogon, Hetoropogon, Themeda Arundenella as well as Vitex and Sida species may be useful.
  • (iii) Planting of appropriate medium size trees in the fields and foot hills of hills towards the leeward side to protect the areas from wind and storm erosion.
  • (iv) Discouraging planting if Eucalyptus and Acacia confusa species around the fields, roadsides and hill slopes etc and substitution by appropriate species.
  • (v) Use of crop rotations in the fields as far as practicable using

Crop (paddy) legume - paddy alternation for restoring natural fertility in the fields.

  • (vi) Reduction of burning in the steep areas of hills stoppage of the burning phase during shifting cultivation and substitution of shifting cultivation by the terrace cultivation etc.
  • (vii) Mulching should be done in the fields as soon as the crop season is over.

This can be done by covering the fields using paddy stalks, corn stalks, paddy husks, saw dust etc. so that the soil is not exposed to wind and at the same time the soil gets enriched in organic matter.

  • (viii) Checking of flooding and water logging in the fields
  • (ix) Minimizing the use of inorganic chemicals and insecticides in the fields. Use of such chemicals be made upon advice from experts. Inorganic chemicals should always be used along with compost, FYM and any other organic manure.
  • (x) Watershed should be managed properly in the foothills.
