Abstract
Mountain environments, mountain hydrology, and mountain inhabitant’s livelihood has been affected by climate change in direct and indirect manner, thus by bringing alternation in migration patterns. This research scrutinizes climate change–induced impacts on livelihood and migration in Trans-Himalayan Mustang district of Nepal. Mann-Kendall’s trend test has been used for analysis of rainfall patterns and temperature of 30 years. The impacts of climate change on different aspects of livelihood are studied adopting the DFID framework and the foresight framework is used for understanding drivers of migration. Data from household questionnaire surveys and focused group discussion in remote villages of Chussang and Lomanthang (Upper-Mustang) is used to validate the results of trend analysis and as input data for both frameworks.
Results have indicated winters are warming and precipitation amounts have increased in the months of June and July. Warm winters and less snowfall are leading successively to drying of springs. The annual average minimum and maximum temperature of February showed an increasing trend with a computed p-value of 0.010 and 0.020, respectively. The analysis of annual rainfall showed an increasing trend with the computed p-value of 0.022. The trend analysis of average annual rainfall indicated an increase of (β) 4.075 mm/year rainfall. The rainfall in July showed the increasing trend with p-value of 0.007. Results have shown that the effect in natural capital and the impacts on the livelihood aspects due to climate extremes will ultimately impacts human mobility. Natural capital was found mostly affected by the climatic variability which includes water shortage, the decline in agriculture production, and insect infestation. The impacts were extended to low family income, low quality of education, shortage of food, etc. Climatic variability has been affecting the livelihood of people now and will do so in the future. This study recommends for adopting appropriate management of the water resources, organic pest management at the local level, water- and nutrient-efficient modern technologies in farming, and appropriate structure for education, transport, and health for increasing the adaptive capacity of the mountainous populations of the area.
