The development of water resources in A&N Islands requires an approach that is regional in scale and holistic in scope. Planning and management of water resources at a regional scale will increasingly demand an integrated overview of different types of hydrological data gathered from different sources. Remote sensing could be used to define the representative sites, guide the field work and generate thematic layers such as surface hydrology, geomorphology, geology, vegetation, rainfall and human impact. It can be achieved by water resource planning at macroscale, understanding, modelling and monitoring water bodies and their catchments at watershed scale and efficient management of augmented water in the command area. In addition to water resource development schemes (medium and minor projects
including digging wells and ponds, constructing check dams and artificial groundwater recharge structures), environment aspects should be maintained with the prevailing socio-economic settings and fragile ecosystem of the Islands.
