The 1:1 million wasteland maps prepared by NRSA showed ve dl To
11.2 that 146 districts had wastelands covering more than 15 per
cent of their area. These districts were considered as critical
(except for border districts) and selected for detailed mapping f E
in Phases I and II (1986 — 89). In Phase III (1990-92), districts V T.

Since the workload in the project was enormous, all the State S t
Remote Sensing Centres and some central organizations were SH '

standard and a uniform system, a manual of wasteland
mapping procedures was prepared giving details of mapping
37.5 and final drawing. Training workshops were organized at
NRSA to instruct all the scientists involved in the project.

wise area under wastelands are shown in tables 6 & 7. About
5000 wasteland maps covering the country were prepared
and under this project. After completion, the maps are sent to
various state users for wasteland reclamation measures. Brief
reports for each district provide a general description of the
wasteland and its distribution. User interaction workshops
have been held in different states to demonstrate the utility of
wasteland maps in reclamation activities and to instruct users
in making the best use of such materials. An atlas covering the
statistics of entire country is released for public by hon'ble
Prime Minister of India Sri A. B. Vajpayee on 22™ May, 2000
