Out-migration is one of the most recognized adaptation practices when dealing with scarce resources and disasters. With general objective exploring migration as an impact climate-induced disasters, our study was conducted in Khaniyapani, Sunapati rural municipality Ramechhap district, Nepal. Disaster prioritization using pair-wise ranking method, results suggesting that drought soil erosion are severe disasters area. The severity maps were prepared remotely sensed data. A Normalized Difference Drought Index Revised Universal Soil Loss Equation used to produce maps, respectively. Approximately 46.2% total area found experience droughts, almost 10% had high rates. In total, 100 out 794 households interviewed for a semi-structured questionnaire. directly livelihoods due decline agricultural productivity, livestock, drying water sources. Out families, 64 practiced seasonal migration. productivity scarcity identified influencing push factors. Excessive has reduced resilience these families. Drought-resistant land, water, crop management techniques practices, alternative income-generating activities should be promoted curb
