Assessing homestead agroforestry-based livelihoods in Sivasagar District of Assam, India, using livelihood significance index (LSI)

Abstract

This study evaluates the significance of homestead agroforestry (HAF) systems for rural livelihoods in Sivasagar District of Assam, India, using Livelihood Significance Index (LSI). The research integrates both quantitative and qualitative methods to offer a comprehensive analysis of how HAF systems contribute to rural livelihoods. The study reveals that the importance of various HAF plant species has undergone significant shifts over the past decade due to socio-economic changes, such as rising household expenses, market-oriented economic transitions, and urbanization. Among these species, Bambusa arundinacea has the highest livelihood significance, with an average LSI of 2.79, although this has decreased by 0.71 % from 2012 to 2022. Conversely, Tectona grandis, despite its low livelihood significance, has experienced a decadal increase in LSI of 20.5 %. This indicates that, while such species currently play a lesser role in community livelihoods, their importance is gradually increasing due to their economic benefits. The study also identifies several challenges, including the loss of traditional knowledge, the vulnerability of agroforestry systems to environmental changes, and difficulties in maintaining biodiversity amidst market pressures. To address these issues, the study advocates for sustainable agroforestry practices in the district that integrate both traditional and economically valuable species while improving market access for traditional products. In flood-prone villages like Afala, introducing flood-resistant species such as Mangifera indica, Artocarpus heterophyllus, and Bambusa arundinacea, along with training in value-added production, can enhance resilience and livelihood sustainability. Together, these approaches aim to cultivate a resilient and sustainable agroforestry landscape in Sivasagar District and beyond.
