Majority of farmer (79.17%) perceived changes in climate variability in the recent years. 86.67% of total household perceived that monsoon rainfall was shifted later, 90% of farmers perceived pest dynamics, 92.59% felt increased pest population in compare to 10 years back, 76.85% experienced emergence of new pest and 34.26% experienced pest resurgence. In Chitwan, annual average temperature and maximum temperature are decreasing but minimum temperature is increasing by 0.001 degree celsius whereas in Dhading maximum temperature is increasing in contrast to decreasing annual average and minimum temperature.
