Mapping of extent of urban sprawl and by monitoring the temporal changes, the impact of changing land use on land, ecology and environment system can be assessed.

Watershed response to produce runoff by a rainfall event depends upon the watershed characteristic and each watershed has its exclusive characteristics. However, most of the watersheds lacks in the facility of recording runoff, in such a case, morphometric parameters of a watershed are valuable information to evaluate watershed capacity to produce runoff.

Rain is the only source of water on the earth and for conserving this precious resource, the base is the land. Shortage of rainfall coupled with its erratic distribution during rainy season causes severe water deficit conditions resulting in various intensities of droughts. Drought varies in different parts of the world depending on the amount and reliability of rainfall received in a particular region. Gulbarga district is one of the drought prone districts of the Karnataka state.

SHILLONG, May 10 – The Central Silk Board (CSB) and State Space Application Centres has taken up a project to extend the silk cultivation area in the State to meet the growing demand of silk in the country thereby provide employment in the rural areas of the State. The current demand for silk is 30,000 ton but the country produces about 23000 ton, according to the CSB. The board is trying to extend the cultivation of silk in non-traditional areas like Punjab, Haryana, Madhya Pradesh, etc.

To offset the effects of climatic change and global warming in the country, the Pakistan Forests Institute (PFI), Peshawar has completed a comprehensive study to determine the climatic change scenarios in Pakistan’s various ecological zones and its impact on forests resources.

The seasonal variability of biomass open burning activities in the Greater Mekong sub-region (GMS) with focus on carbon monoxide (CO) and total particulate matter or aerosol (TPM) emissions was investigated in order to document the characteristics of this significant source of air pollutants in the region.

The Advisor to Ministry of Environment and Forests, G. V. Subrahmanyam, has said that people's participation in environment protection alone can bring the desired results more than any number of legislations brought by the Government.

“Protecting the environment is for our own future and not for anybody else. You can have any number of legislations…but the implementation is done by local people. Any campaign on climate change or environmental issues can be successful only when all of us come together,” he said, while speaking at the Thiagarajar College of Engineering (TCE) here on Friday.

Bangalore As revised estimates point to a two-fold increase in India's potential for wind energy generation with the use of taller towers for wind turbines, the Centre for Wind Energy Technology (C-WET) is setting up 75 monitoring stations across the country to validate the prediction and also assess the land availability.

The initiative, which would involve measuring wind speed from towers as tall as 100 metre, comes more than a decade after the centre embarked on a similar exercise to validate the potential at 50-metre hub heights. Wind speeds are greater at higher tower heights, though the density is lower.

Wind potential estimates in India needed to be reassessed to keep pace with improving technologies in the field. This study shows that the country had the capacity to yield wind power in the range of 600 to 1000 GW with current available technologies. The study uses internationally acclaimed methodologies in wind potential assessment to calculate on-shore wind potential in India.

Monitoring of water and land objects enters a revolutionary age with the rise of ubiquitous remote sensing and public access. Earth monitoring satellites permit detailed, descriptive, quantitative, holistic, standardized, global evaluation of the state of the Earth skin in a manner that our actual Earthen civilization has never been able to before. The water monitoring topics covered in this book include the remote sensing of open water bodies, wetlands and small lakes, snow depth and underwater seagrass, along with a variety of remote sensing techniques, platforms, and sensors.
