The rate and intensity of Land Use Land Cover (LULC) change has increased<br />
considerably during the past couple of decades. Mining and urbanization bring<br />
significant alterations in LULC specifically due to its impacts on forest cover and<br />
agricultural lands. Land use land cover in Angul Talcher region is changing rapidly due<br />
to increase in mining activities urbanization pattern. The areas under forest cover and<br />
agricultural land have decreased from 38.67% to 27.96% and 42.<strong>14</strong>% to 28.92% over<br />
the study period (1973 – 2007) respectively. The water bodies have slightly decreased<br />
(0.07%) from 1973 to 2007. Mining areas and barren lands have increased from 0.04%<br />
to 1.70% and 5.50% to 20.78% since 1973 to 2007. The maximum rate of change of<br />
land use land cover has decreased in agricultural land (-0.92%) and forest cover (-<br />
0.81%). The study revealed that mining activities and urbanization were detrimental to<br />
LULC. Thus, it is advisable that such activities have to be strictly regulated to avoid<br />
further damage and scientific mining has to be taken up in a proper manner to minimize<br />
the land use land cover.<br />
WEAKENING OF ZONAL TEMPERATURE GRADIENT<br />
BETWEEN INDIAN LANDMASS AND NEIGHBOURING<br />
OCEANS AND ITS IMPACT ON INDIAN MONSOON<br />

The study shows that in the scenario of global warming temperature gradient (TG)<br />
between <strong>India</strong>n land mass and Arabian Sea/Bay of Bengal is significantly decreasing in<br />
the lower troposphere with maxima around 850 hPa. TG during pre monsoon (March to<br />
May) is reducing at a significant rate of 0.036°/ year (Arabian Sea) and 0.030°/year<br />
(Bay of Bengal). The above alarming results are based on sixty years (1948-2007) of<br />
daily temperature and wind data extracted from CDAS-NCEP/NCAR reanalysis data<br />
sets. TG based on ERA-40 data also indicate a decreasing trend of 0.023°/year and<br />
