摘要

This study assessed the impacts of climate change on wheat and paddy yields and examined local adaptation practices in Jumla district, Nepal, using both primary and secondary data. Primary data was collected through 62 key informant interviews (KIIs) and 12 focus group discussions (FGDs) conducted from April 2 to 11, 2024. Trend analysis of 30 years (1993–2022) of climatic variables was conducted using the Mann-Kendall test and Sen’s slope. The trend analysis showed that annual maximum and minimum temperatures increased by 0.055 °C/year and 0.070 °C/year respectively, and annual average rainfall increased by 5.39 mm/year. Extreme climate event indices such as very wet days (VWD), number of rainy days (NRD), extreme wet days (EWD), and consecutive dry days (CDD) increased, while consecutive wet days (CWD) decreased annually. Pearson’s correlation was used to examine the relationship between climatic factors and crop yields. The result showed that currently both maximum and minimum temperatures had a positive impact on wheat and paddy yields, but if they crossed the threshold temperature, they could potentially impact production negatively. Furthermore, local perceptions supported these findings, with respondents reporting rising temperatures, frequent disasters such as landslides, floods, and hailstorms, and declining crop yields over the past years. In response, farmers adopted measures such as changing crop varieties by planting Chandannath-1, Chandannath-2, Lekali-1, Lekali-2, Black Rice, Jumli Marshi, and NR10481 in paddy and WK 1204, Mudule 1 (WK 1712), Tila (WK 2370), Dhaulagiri, Annapurna 1, and Annapurna 4 in wheat, shifting to animal husbandry, and practicing tunnel farming. The study emphasized the need for long-term adaptation programs to strengthen agricultural resilience and safeguard livelihoods in Jumla.
