India's monsoon dependent agriculture is highly vulnerable to the impacts of climate change, and inadequate policies contribute to socio-economic difficulties in farming communities. Many current policies and strategies to combat climate change impacts are focused on technical aspects of adaptations whereas little research is done to understand the socio-economic dimensions, particularly the perspectives of farmers. To address this gap, we conducted semi-structured interviews with more than 800 farm-families residing in the Northeastern Region of India (NER), an Eastern Himalayan ecosystem. Results show that most farmers perceive changes in climate and are aware of its agricultural and socio-economic impacts. The majority of farmers from all eight NER states have personally experienced unusual climatic events within the last 10–15 years. About two-thirds believe that climate change is largely man-made and there is an urgent need to take action. Many farmers observed declining water availability and soil fertility across NER. High cost of agricultural inputs and unawareness of effective adaptation technologies are the core barriers for adaptation in NER. To sustain their livelihoods, vulnerable farmers have adopted a few low-cost measures. However, strategic interventions are highly advocated to empower human capital for enhancing socio-ecological resilience. In conclusion, to overcome the barriers of farm adaptations in NER, holistic support programs are needed, which raise awareness for suitable actions, reduce input costs, and facilitate access to financial credits.

Tribal farmers in the Himalayas are vulnerable to climatic changes, as their rain-fed cultivation systems, practiced on steep, sloping terrain, are susceptible to changes in rainfall while at the same time being the primary means of livelihood. Soil and water conservation practices (SWCP) can improve the resilience of these cultivation systems to adverse climatic conditions. However, little is known about adaptation within these tribal farming communities. This is the first empirical study on the adaptation decisions of tribal farmers in the Himalayan uplands of Northeast India. Starting from the analysis of future climate risks, we surveyed 372 tribal farmers in Nagaland state to analyze perceived climate and environmental changes in relation to socio-demographic factors. We estimate current adoption rates of SWCP together with farmers' goals and values and employ a binary logit model (BLM) to quantify the influence of diverse factors on adaptation decisions. Our results show that increases in temperatures and crop diseases were the most perceived changes by tribal farmers. Climate projections indicate that precipitation amount and intensity, along with temperatures, will increase towards the end of the century, underlining the importance of SWCP. However, all considered SWCP were employed by less than half of the tribal farmers. Adoption probabilities for all practices were significantly increased when farmers participated in agricultural training. After that, participation in a civil society organization, livestock ownership, high-altitude locations, and perceived increases in droughts were found to increase adoption probabilities significantly, while socio-demographic factors were of only minor importance. If the most effective factor was employed to all farmers, average adoption rates of SWCP could at least double. Adoption decisions were mainly motivated by improving livelihoods, sustaining natural resources, reducing workload, and preserving cultural aspects of cultivation. This research contributes to understanding adaptation decisions of tribal farmers and quantifies the untapped potential for climate change adaptation of marginalized and climate-vulnerable farming communities in mountain regions. [Display omitted] • Most farmers observed rising temperatures and crop diseases and declining rains and yields. • Soil and water conservation practices (SWCP) are used by less than 50% of tribal farmers. • Exploiting unused adaptation potentials could double adoption rates of SWCP. • Agricultural training is the most influential factor for adaptation. • Improving livelihoods and conserving natural resources are farmers' major motivations.
