Shifting Cultivation in NE States
|
Shifting cultivation (Jhum) is a common land use in many states, particularly in the North-Eastern region of the country. Regarding areas affected by shifting cultivation there are varying estimates by different agencies. The area affected by shifting cultivation in the North-Eastern region was reported to be 3.81 million ha by a Task Force on shifting cultivation (1983). Other such estimates are 2.80 million ha by North-Eastern council (1975) and 7.40 million ha by FAO (1975). To generate a reliable information, FSI undertook a similar study. The assessment done on 1;250,000 scale relates to the period between 1987 and 1997. The region is covered by 33 SOI toposheets on 1:250,000 scale. The satellite data on 2 years interval corresponding to the periods 1987-89, 1989-91, 1991-93, 1993-95 and 1995-97 have been used. The sensors were Landsat TM and IRS 1B (LISS II). Visual method of interpretation was adopted.
