Sustainable agriculture in Northeastern India: how do tribal farmers perceive and respond to climate change?

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.
