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.

Concentrations of trace metals in the flesh of nine fish species commonly found in commercial
catches of a hydro-power reservoir in Sri Lanka (Victoria) were detected using the
Neutron Activation Technique. High concentrations of Al (37.8 - 208.0 μg•g-1 dry wt.) and Rb
(20.90 - 70.75 μg•g-1 dry wt.) were found in all nine species while the concentration of Zn
ranged from 20.29 to 92.00 μg•g-1 dry wt. but was found only in four species. Au was detected
in seven species but the concentration ranged from 0.004 to 0.043 μg•g-1 dry wt. The concentration

The Gujarat 2001 earthquake drove home the point that cities built on river alluvium and sand are likely to suffer maximum damage from an earthquake due to high water table and the construction of dams in the upper reaches

During the last hundred years or so, deforestation and wind-water borne soil erosion have been steadily increasing and have now become the major environmental problems the world over.
