The study of land-use pattern using remote sensing is a popular tool for researchers after the advent of high-resolution multispectral imagery.

Atmospheric aerosols (a mixture of solid or liquid particles suspended in the air medium) are short-lived, with a residence time of about a week in the lower troposphere. Unlike the principal greenhouse gases, aerosols are more concentrated in the source regions and exhibit strong spatial and temporal variations.

As more and more ice slides into the ocean, sea levels are rising faster and faster

A study was carried out for the simulation of sediment yield from an agricultural watershed falling in laterite zone of West Bengal using event scale Modified Universal Soil Loss Equation (MUSLE).

The groundwater recharge zone mapping often requires a large amount of spatial information and criteria. Geographic information systems are capable of managing large amount of spatially related information, providing the ability to integrate multiple layers of information for multi-criteria analysis.

Water resources in Taiwan are unevenly distributed in spatial and temporal domains. Effectively utilizing the water resources is an imperative task due to climate change. At present, groundwater contributes 34% of the total annual water supply and is an important fresh water resource. However, over-exploitation has decreased groundwater availability and has led to land subsidence.
