Abstract
Nepal is one of the most vulnerable countries in terms of climate change in the world, and it comes fourth most vulnerable nation among the south Asian countries. The effect of climate variability on maize crop yield in the local context have not been explored yet. Therefore, a thorough grasp of the local context’s climate change variability may help with the development of locally appropriate adaptation strategies for present and future climate hazards. This study examines the impacts of climate variables (annual rainfall and annual average temperature) on the yield of maize crop in the hill agro ecological zone of Nepal. The historical climate data starting from 1990–2021 were collected from the Department of Hydrology and Meteorology, and the production data of maize crop were collected from the Ministry of Agriculture and Livestock Development, Nepal. Collected data were analyzed (Multiple Regression and Correlation Analysis). The trend analysis showed the increasing trends of both climatic variables. The result revealed that the annual average temperature was a significant positive impact with the p-value 0.007 whereas, the annual average rainfall and maize production showed the negative correlation results with the p-value 0.944. Therefore, the results of this study imply that the changes in climatic variables considerably positive impacts on maize production in current situation however the rising trend of temperature show the threaten for future, and emphasizing how urgent it is to implement farmer-initiated and locally driven adaptation strategies for resilient agricultural systems and food security.
