Abstract

Although the understanding of the impact of climate change continues to improve, it is as yet difficult to identify the specific regional impact with any precision. This uncertainty remains a key constraint and major challenge in both, formulating and implementing policies related to adaptation. Climate change represents a loss of information; the value of historical data in guiding water resources decision-making is degraded and future conditions are subject to a high level of uncertainty. With the very high variations of topography and rainfall, projection of future climate trends will be especially difficult for Himachal Pradesh.
