MPLICATOIN OF IRRIGATION WATER REQUIREMENT FOR WHEET AND CLIMATE CHANGE PARAMETERS-A CASE STUDY OF COMMAND AREA OF URBC
Keywords:
Irrigation Water Requirement (IWR), Metrological parameter, FAO 56, CROPWAT.Abstract
The major changes in climatic parameters are temperature and in rainfall which have direct impact on
irrigation water requirement in arid and semi-arid region. In order to establish the implications of
irrigation water requirement and the climate change parameter, the recent past ( say 2015) irrigation
requirement and 5 decades later in the year 2065 the irrigation water requirement were calculated
based on prediction for a particular crop in the study area. Considering negligible change in the
regulations relating to agriculture and irrigation over the period of 50 year, the variation in IWR were
observed increased significantly. The observed increase in irrigation water requirement after 50 years is
mainly due to increase in temperature, population raising and probable industrial growth. This study will
be helpful to propose the improvement in surface water supply, regulation of green house emission by
anthropogenic activity and better usage of ground water resources to supplement the excess irrigation
requirement of crop. In future, for sustainable irrigation system, only the current data and conventional
methods are no longer survived to overcome the irrigation water requirement. The global change in
climatic parameters need to considered remarkably.
