Climate change vulnerability and adaptation among farmers practicing shifting agriculture in the Indian Himalayas

The compounding and cascading effects of climate change induced by anthropogenic activities threaten the livelihoods of indigenous communities living in fragile ecosystems and practicing shifting agriculture in mountainous regions. This study assessed differences in household-level climate change vulnerability and socioeconomic profiles of indigenous communities practicing shifting agriculture in the Indian Himalayas using the Intergovernmental Panel on Climate Change (IPCC) framework. A total of 120 randomly selected households spread across 12 randomly chosen villages were surveyed, making sure that at least 10 households per village in Dima Hasao, Karbi Anglong, and Cachar districts of the state of Assam using the indicator-based household-level questionnaire to examine the cause and characteristics of vulnerability in the study region. Furthermore, focus group discussions were held in each village to delve into the community-based adaptive strategies employed by hill farmers, aiming to acquire an in-depth understanding of their approaches. The results revealed that villages with higher susceptibility to climate change are characterized by lower literacy levels, smaller land holdings with poor soil fertility, greater losses of crops due to extreme events, greater dependency on natural capital, and lower livelihood diversification. Villages with better land management techniques, higher decision-making abilities, agricultural diversification, and good market access had better adaptability to climate change. Agricultural diversification, transitioning from shifting agriculture to high-value cropping such as agroforestry, coupled with indigenous knowledge of the communities, provided tangible and intangible benefits and ecosystem services. Integrating high-value crops in shifting agriculture contributed to greater economic returns. In conclusion, shifting agriculture plays a vital role in the survival of ethnic culture, heritage, religious beliefs, and the livelihoods of nature-oriented hill farmers. Furthermore, improving fallow land management is crucial for maintaining ecological equilibrium and ensuring the sustainability of hill farmers' lifestyles by fostering a communityenvironment-development nexus. Finally, we discuss the methodological implications of vulnerability assessment in the context of this study.
