Remote Sensing

Aerial photography can yield qualitative and quantitative information on changes in environmental conditions. Remote sensing can be used to provide information on the environment at a wide range of scale. At local scales it can be used to study a small area in considerable spatial detail. Spatial resolution data sets provide valuable data on the environment especially in the context of changes. The studies of this type which have been performed on the expansion of dry regions
(examples: Sahara, Sahel) are well known [17-24]. Changes in the condition of large bodies of water can be detected in the same way.

Studies in South India [25] have shown that satellite remote sensing techniques can provide reliable and objective data on water quality, agriculture productivity and related water management aspects.
