India has made rapid progress in food grain production during second half of the 20th century in which Punjab has played a leading role. However, the growth rate in the state has slowed down over the years and now there is practically a plateauing of the productivity of wheat and rice, the two most important food grain crops.
Global human population has been expanding exponentially, from 2.5 billion in 1950 to ~6 billion in 2000, and is likely to reach 10 billion by 2050, and thus the demand for natural resources is significantly increasing. It has resulted in rapid, extensive and persistent changes in earth ecosystems, more in the past 50 years than at any time in human history.
Geomorphology is an important aspect which guides immensely in urban planning. Mapping of geomorphology not only gives an idea about the variations in landscape but also indirectly facilitates in evaluating the resources of an area. Present study shows the capability of satellite data in delineating major geomorphological units in an industrial area like Korba city.
The southern Western Ghats tropical montane cloud forest sites (Gavi, Periyar, High wavys and Venniyar), which are characterized by frequent or seasonal cloud cover at the vegetation level, are considered one of the most threatened ecosystems in India and the world.
Occurrence of antibiotics was investigated in water associated with two hospitals in Ujjain district, India. Samples of hospital associated water were subjected to solid phase extraction combined with high pressure liquid chromatography-tandem mass spectrometry (LC-MS/MS), to estimate antibiotics in incoming safe water, hospital wastewater and groundwater.
The Genetic Engineering Approval Committee (GEAC) cleared Bt brinjal for commercialization on 14 October 2009. The activists are up in arms terming the approval as a shame. The government has chosen to go slow and states that it would consult the stakeholders before making a decision on the release.
Desertification is the process of land degradation in arid, semi-arid and dry-subhumid areas. This communication describes the classification system, methodology and the results of desertification and land degradation status mapping carried out for the entire country on 1 : 500,000 scale using multi-temporal
Resourcesat AWiFS data.
The diversity and spatial patterns of polychaetes, a proven proxy for environmental assessment studies, were studied in 28 stations covering subtidal and intertidal segments as well as bunders and docks of the Mumbai Port. Univariate and multivariate analyses of polychaete data were used to determine the level of environmental degradation in various segments of
