Abstract:
Water resources management in arid and semiarid areas is a complex proposition,
which involves consideration of a large number of hydrologic, environmental and
management factors to ensure supply of sufficient water and minimum levels of
environmental protection. For quite some times from now the Bundelkhand region is
under limelight because of the continuous drought situation resulting in acute water
shortage and large-scale migration of location population elsewhere in search of livelihood.
The region is under constant water stress and facing severe scarcity of water for
agricultural and domestic use. More than 80% of the population is dependent on rain-fed
agriculture with only 20% of the net sown area being irrigated. Management of water on
scientific principles by adoption of appropriate drought management strategies is
therefore imperative for the sustainable development of Bundelkhand. The various
components analyzed for detection of climate change signals and drought characteristics
include departure analysis and probability analysis of annual and seasonal rainfall, trend
analysis of climatic variables, dry spell analysis including the onset and duration of critical
dry spells, supplemental irrigation requirement planning during critical dry spells, and
detection of trend in critical dry spells lengths and frequencies.
