This paper on the state of Himalayan Glaciers by V K Raina, ex Deputy Director of GSI presents a historical review of the research to date spanning more than fifty years, and claims that it is premature to accept that Himalayan glaciers are retreating abnormally because of global warming.

The knowledge of hydrological variables (e.g. soil moisture, evapotranspiration) are of pronounced importance in various applications including flood control, agricultural production and effective water resources management. These applications require the accurate prediction of hydrological variables spatially and temporally in watershed/basin. Though hydrological

If the next climate treaty tackles deforestation, tropical nations will need to monitor the biomass of their forests. One ecologist has worked out a way to do that from the sky, finds Jeff Tollefson.

Way back in 1990, a US study concluded the emission of methane from paddy fields in India was as high as 38 million tonnes a year. This was when India did not have its own research capability to measure this. But, at least one Indian scientist dismissed the findings.

Oct. 12: Rattled by the recent floods, the irrigation department has decided to make use of digital sensors to monitor water movement across rivers more quickly.
The department will soon set up this system which will work with the aid of satellite technology.
It is also planning to build small reservoirs to store the flood water in the lines of Hirakud reservoir.

Himalayas has one of the largest concentrations of glaciers and permanent snow fields. These are sensitive to climate change. Snow and glacier runoffs are important sources of water for the Himalayan rivers. Due to steep slopes, all these streams are potential sites for hydropower generation.

DINDIGUL: The Gandhigram Rural University has plans to conduct a mega research project at an estimated cost of Rs.4 crore to study all water bodies in the State and their changes between 1970 and 2009.

The research is aimed at finding out reasons for their changes.

In this paper an attempt has been made to analyze the sedimentation surveys and rates in live storage capacity of reservoirs. The analysis is based on the available data of 28 reservoirs from different basins of Maharashtra.

In the study, 57 medicinal plant species belonging to 45 genera and 36 families have been recorded. Out of these, the most important species found were Aesculus punduana, Boerhavia diffusa, Dillenia pentagyna, Holarrhena antidysenterica, Justicia adhatoda, Oroxylum indicum, Rauvolfia densiflora, Rauvolfia serpentina, Terminalia arjuna, Terminalia belerica and Terminalia chebula.

In the present report, an attempt has been made to review the various methods for assessment of ground water recharge, present perspective of ground water resources assessment in the country and to suggest the future strategies for refinements of the
methodology for assessment of ground water resources.
