Abstract
In the context of climate change, the frequency and intensity of extreme events such as floods and droughts will increase which could put tremendous challenges in water resources management in the coming days. While scientific knowledge on climate threats and changing climate patterns are essential, it is also important to consider the impacts in relation to how the threats are perceived and handled by local people. This paper intends to assess the trend and people’s perception on temperature and precipitation. Three focus groups’ discussion and a total number of 240 households were interviewed during field visit. The collected information was scaled from the least preferred-1 to the most preferred-5 based on their preferences. The trend of mean of annual average, maximum and minimum temperature indicates that the temperature has increased significantly and precipitation intensity and magnitude are also in increasing trend in the monsoon and postmonsoon seasons which may raise the extreme flood events. These facts were verified with the people’s perception. This finding could be useful for formulation of effective flood management policy and plan in this river basin as well as very applicable for other similar areas.

Climate change is gradually becoming a major concern to mankind but most of the people, who are most vulnerable, are not aware of the real consequences of the global warming
The temperature is increasing at a faster rate in West Rapti River basin than the average of Nepal and global
Rainfall intensity and magnitude are increased in the monsoon and post-monsoon seasons rather than in the pre-monsoon season which may raise the extreme events such as floods
Summary
Climate change is gradually becoming a major concern to mankind but most of the people, who are most vulnerable, are not aware of the real consequences of the global warming. It is recognized as a major threat to the communities in the rural areas who are more dependent on the natural resources [1]. Temperature in Nepal is increasing at a high rate in recent years similar to the phenomenon observed.
