Pastoralism in the Himalayan region of Nepal has undergone significant socio-economic and ecological changes. While there are numerous contributing factors behind these changes, the effect of a changing climate has not been thoroughly studied. This paper adds a significant contribution to the knowledge base through analysis from a survey of 186 herder households, interviews with 38 key participants, and four focus group discussions with individuals from three National Parks and Conservation areas in the high-mountain region of Nepal. Additionally, a review of the existing policies and programs on pastoralism was carried out. Results demonstrate several reasons behind the decline of transhumance pastoralism: Policy focus on the establishment of conservation areas, increasing vulnerability to extreme events (avalanches, snowfall, storms, and disappearing water sources), and ineffective government policies and programs. Hardships involved in herding combined with changing social values and the degradation of pasture quality were identified as contributing factors to the growing challenges facing mountain pastoralism. Similarly, the declining interest among herders to continue their profession can be traced to vulnerability associated with escalating climate change impacts. Considerable knowledge gaps regarding threats to high-altitude pastoralism remain, and continued research on pastureland conservation, capacity development, facilitation for climate change adaptation, and coping strategies for herders in the high mountains is urgently needed. Our analysis suggests that non-climatic variables such as policy and globalization were more influential in eroding pastoralism as compared to climate change.

Land management and forests are crucial to tackling the concurrent issues of sustainable food production and climate change. Conventional modern agriculture, converting forests and naturally vegetated landscapes to farms and rangelands, contributes significantly to elevate carbon in the atmosphere. Agroforestry systems offer potential for local communities to meet livelihood needs while simultaneously adapting to and mitigating climate change. Data from several studies conducted in nine districts of central Nepal between 2007 and 2017 were analyzed. Forests and agroforestry systems in three central Nepal districts had significantly higher total carbon stocks than agricultural soils (2–5 times) due to high above and below-ground biomass carbon and SOC stocks. The application of improved FYM compost, cattle urine and biochar in four districts increased average SOC by 2.75% over 6 years, translating to an increase of nearly 100 t ha−1 in SOC stock. Along with soil quality benefits, biochar and FYM compost improved the yields of soybean, potato, millet and Swertia chirayita yields which were significantly higher than in untreated plots. The flux of N2O was significantly lower in biochar-amended soil compared to non-biochar. Crop diversification incorporating high-value horticultural and medicinal crops enhance economic returns as indicated by higher benefit-cost ratios for vegetable and Swertia chirayita than for cereals.
