The focus in this paper is to understand the likely influence of climate change on vector production and malaria transmission in India.

Sea level changes can be of two types: (i) changes in the mean sea level and (ii) changes in the extreme sea level. The former is a global phenomenon while the
latter is a regional phenomenon. Estimates of mean sea level rise made from past tide gauge data at selected stations along the coast of India indicate a rise of
slightly less than 1 mm/year; however these estimates need to be corrected by including the rates of vertical land movements, whose measurements are not available

This study pertains to analysis of Airborne Synthetic Aperture Radar (ASAR) images in mapping the flood inundation and causative factors of flood in the lower reaches of Baghmati river basin for the period July

The distribution trends of trace elements over North and South Krishna delta were examined in relation to fresh-, brackish- and saline-water zonations. Strontium and boron have shown significant variations in fresh-, brackish- and saline-water environment. Strontium has shown a variation from 23 to 1500 mg/l in freshwater, 1650 to 2760 mg/l in brackish water and

We attempt to synthesize available quantitative, precisely
dated and high-resolution palaeorecords of the South Asian summer monsoon from different natural archives, highlighting their similarities and differences.

The rivers draining the Gangetic plains exhibit remarkable geomorphic diversity, and this has consequently characterized the rivers to be dominantly aggradational in the Eastern Gangetic Plains (EGP) and degradational in the Western Gangetic Plains. We suggest that steam power and sediment supply are the two main fluvial parameters which govern the aggradation or degradation in river systems which, in turn, are controlled by inherent catchment parameters such as rainfall and tectonics. The

low level jetstream (LLJ) with its core at an altitude of about 1.5 km and core wind speeds of 80

Two cases of intense western disturbances which affected the northwest India have been investigated using the India Meteorological Department’s operational limited area analysis and forecast system. The model results are compared with the synoptic observations, which have been enriched by additional stations installed under the national project ‘Parwat’. The analysis shows that the 24-hour model forecasts are in good agreement with the observations both in respect of western disturbance’s movement and intensification.

Analysis of multi-date satellite sensor data and maps indicated loss of 1836 ha of land during 1976–2001 along the Godavari deltaic coast resulting in displacement of coastal communities and mangrove destruction. Decrease in sediment loads from an annual average of 145.26 million tons in 1971–79 to 56.76 million tons during 1990–98, apparently due to construction of dams, largely diminished vertical accretion at the delta, while continued coastal subsidence that might have been accentuated by possible neotectonic activity and consequent relative sea level rise led to shoreline retreat.

Digital processing of the IRS-1D LISS-III image revealed a highly degraded state of the Kolleru lake.
