With the help of geospatial technology, it is possible to generate and update information about natural resources, in spatial format, at much more frequent intervals, so enabling proper inventory and management of natural resources, said P. Subbian, Registrar, Tamil Nadu Agricultural University (TNAU).

Inaugurating a 21-day summer training on “Geospatial Technologies and Applications” at TNAU, he said the Indian geospatial industry’s current annual productive capacity was nearly Rs. 4,000 crore.

A large number of cities across the country continue to function without a Master Plan, despite the Centre offering funds to carry out the exercise and the recognised benefits of a plan. The Union Urban Development Ministry on Wednesday claimed that only 24 per cent of the total cities and towns have a Master Plan.

Secretary Urban Development, Sudhir Krishna used Delhi and its water-logged roads as an illustration of just how important a Master Plan is for a city. “The Master Plan should include information on all the crucial aspects of a city, for instance the natural drain network.

The State Forest Department will spend nearly Rs. 6 crore for maintenance of degraded plantations raised on 47,000 hectares and carry out buffer zone activities in 230 villages this year.

Along with activities under infrastructure improvement, forestry extension, research, monitoring and evaluation and GIS, the buffer zone activities will be carried out this year under Tamil Nadu Afforestation Project (Phase II). The project is being implemented from 2005-06 to 2012-13 with an outlay of Rs. 567 crore in 950 villages (800 under Japan International Cooperation Agency and 150 under State funds).

This biodiversity atlas of the Indian waters in the Exclusive Economic Zone overlays available GIS data on oceanic species and habitats, sea grass, seamounts and charismatic megafauna like dolphins, whales and turtles to recommend conservation and management for some areas.

This study used ZIP code level data from the 2000 US Census to investigate the influence of local environmental, social, economic and political variables on the distribution of residential solar PV arrays across the United States. Current locations of residential solar PVs were documented using data from the National Renewable Energy Laboratory's Open PV project. A zero-inflated negative binomial reression model was run to evaluate the influence of selected variables. Using the same model, predicted residential solar PV shares were generated and illustrated using GIS software.

Even as the environment ministry continues to come under pressure to fast track coal mining in forest areas, this analysis by Greenpeace shows how coal mining threatens over 1.1 million hectares of forest in 13 coalfields alone in Central India.

Meghadrigedda, a non-perennial drainage system is one of the major water resource systems of Visakhapatnam city located in the north coastal part of Andhra Pradesh, India. The study was intended to present a twodimensional approach to describe the properties of Meghadrigadda drainage morphometry at sub-basin level using GIS as a tool for the analysis.

Increasing urban surface temperature due to change of natural surfaces is one of the growing environmental problems in urban areas, especially in cities like Delhi. The present work is an attempt to assess the urban surface temperature in Delhi using remote sensing and GIS techniques. ASTER datasets of thermal bands were used to assess the land surface temperature (LST) using temperature emissivity separation technique. Ward-wise population density was calculated from the Census of India 2001 data to correlate the population density with LST.

By its own admission, 40 per cent of the water supplied by Delhi Jal Board (DJB) is non-revenue water. Now, the DJB is finally set to launch its ambitious project to plug revenue losses.

JAIPUR: Climate change, the greatest global challenge, is already a reality for the farmers of Rajasthan. It is increasing the pressure on already scarce resources and if proper measures are not taken, migration towards the cities will soon reach new heights.

According to the Rajasthan State Action Plan on Climate Change (RAPCC) report by the Rajasthan State Pollution Control Board prepared with the help of a multi-disciplinary team of experts from TERI with support from GIZ says, 'enough is already known to start action'. And more than the factual situation the action plan that the report suggests is a writing on the wall for farmers.
