abstract decadal changes in land use/land cover for balachaur watershed in nawanshahar district, punjab, india were studied using black and white aerial photographs for march 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (fcc) of irs-1d liss-iii on 1:50,000 scale for march 2002, september 2002, and may 2003 and interpreted visually to prepare land use/land ...

elevated atmospheric carbon dioxide and other green house gases have increased the earth temperature in recent century, which it affects all biochemistry cycles in soils. to examine the effect of atmospheric co2 concentration and temperature on n forms in soil solution in a calcareous soil, an experiment was conducted in a completely randomized design with factorial arrangement in the laborator...

for a few decades has proposed sustainable developing in different sciences and professions including architecture and urbanization and its origins  is in environmental crises  and also excessive use of fossilized energies in the world. problems such as global warming, increasingly developing of green house gases in atmosphere that its origin  is  in global warming , air and soil  pollution, an...

It is being increasingly acknowledged, in both the IS and sustainability literature that the greatest opportunity for “green” information systems is in the reduction of energy consumption and associated green house gases through the optimal design of supply and demand networks. This paper reports the findings of a multiple case study investigation into how a comparatively new green IS framework...

Global warming has today turned to one of the most important environmental issues due tooveruse of fossil fuels, and it needs serious attention. Since the mid-1970s, an urgent needwas therefore felt around the world to reduce the use of energy for heating and cooling inbuildings. Using green covers, especially green facades, in appropriate environmentalconditions can be regarded as a method to ...
