Résumé
Study on land use dynamics in Karnataka was undertaken using 28 years data from 1980-81 to 2007-08. Tabular analysis, growth rate, Markov chain analysis, instability index, multiple linear regression and annual rate of change were employed to arrive at meaningful results. Area under forest showed a marginal increase and a considerable growth in land put to non-agricultural uses and area sown more than once were observed. Barren and uncultivated land, permanent pastures, cultivable wastes and miscellaneous tree crops showed significantly negative growth over study periods. Current fallows witnessed positive growth for the entire period (1.20 %). The other fallows declined (- 1.76 %) in Period-I (1980-81 to 1994-95) and increased (1.87 %) in Period-II (1995- 96 to 2007-08). Net sown area showed positive growth (0.37 %) in Period-I. Markov chain analysis showed that except land not available for cultivation, all other categories showed stability in the Period-I. But in Period-II except fallow land, all other categories have shown stability in retaining their shares. The instability index was found highest for current fallows followed by other fallows in both the periods and for entire period too. The results revealed that the major factors responsible for the changes in land use pattern over years were net irrigated area, road length, population density, literacy rate, number of factories and number of land holdings. Land put to non-agricultural uses and other fallows were the land use categories to exert pressure on cropping intensity. Study noticed that land use shift has been occurring from desirable (14,552 ha) and undesirable (1,518 ha) ecological sectors towards agricultural (5,600 ha) as well as non-agricultural sector (10,447 ha) annually. The study suggested to increase forest cover by afforestation, stabilization of irrigated acreage and to check land shifts from ecological sector to other sectors.
