Agroforestry is the combination of farming practice of agriculture and forestry in the same plot of land. Changes in climate not only distort the farming practices among the Chepang of Makwanpur, who are the 51 indigenous nationalist of Nepal titled as “Praja”. Agroforestry practice is the perfect way out to the Chepang of Makwanpur, familiar to farming practice in khoriya. This study examine that how agroforestry practices help in adopting and mitigating climate change impact and improve livelihood in Raksirang Rural municipality under newly established federal system of Nepal. Nearly 50 households (12 % of total household) in Raksirang Rural municipality (Ward number-5, Niguretar and Rawang communities) were chosen as agroforestry practioner Chepang community using the purposive sampling method. The study result revealed that due to a number of agroforestry practices such as banana (Musa paradisiaca), vegetables, and cereal crops are continuing to improve the livelihood of Chepang, however the overall production in farming is declining due to lack of technical supports, inadequate input support, and change in climate parameters, mainly rainfall patterns and excessive heat. Support services for the farmers in the Pallika level as per new federal structure is somehow fragile as technicians are off, inadequate, limited budget, and remoteness of the locality. The presence of development agencies are also deteriorating due to new federal structure is a challenging to the farmers, who had initiated the farming practice in khoriya. The study concludes that agroforestry practice is an option for adaptation and mitigation of the climate change impacts among Chepang. Local indigenous knowledge is somehow, still in practice to maintain the food security situation of the Chepang. Nutrition and dietary diversity is challenging to find out in the proper situation could be next research for Chepang. Agroforestry is less interested in the pallika and it must be on the top for the sustainable development. Bee hives and Chiuri (Aesandra butyraceae) practice is high in demand.
