Characterization of shifting cultivation, trends, and diversification of livelihood patterns: A case study from forest villages in Barak valley, Assam, Northeast India

Abstract

Shifting cultivation is a traditional agricultural system and predominant land use in the mountainous regions of many parts of the world. Recently, there has been a change in traditional shifting cultivation practice. The purpose of the current study is to map the spatial distribution of shifting cultivation plots in forest villages of Barak Valley, Assam, Northeast India, document the socio-economic profile of cultivators, and examine how traditional shifting cultivation is transitioning towards other agricultural systems, leading to livelihood diversification. The study included both primary and secondary data. The shifting cultivation plots were digitized using Sentinel 2 image of 2022. A total of 146 respondents from nine forest villages were interviewed using a structured questionnaire. The plots were concentrated in the southern part of Barak Valley and sparsely distributed in the Northern part. The average plot size was 1.35±0.02 ha. A positive correlation was observed between family size and size of jhum plot. The villages were located in remote areas with little access to basic amenities such as metalled roads and schools. The duration of fallow was lesser in villages located nearer to the market, as it was easier for them to sell their produce. Diversification of livelihoods among the younger members was observed, who were engaged in activities other than cultivation. The reason cited by respondents for this was earning additional income. Shifting cultivation combined with commercial farming on fallow land was the most common form of livelihood. The fallow period ranged between 2 to10 years. Weed infestation and loss of fertility were cited as major reasons by all respondents for leaving jhum plots fallow. Species such as Citrus sinensis (L.) Osbeck (Orange), Musa sp (Banana), Piper betle L. (Betel Leaf), Parkia timoriana (DC.) Merr. (Tree bean), Thysanolaena latifolia (Roxb. ex Hornem.) Honda (Asian Broom Grass) and other economically important species were cultivated in the fallow lands. This has increased the pressure on remaining forest lands that are being converted into shifting cultivation areas. Although conversion of fallow for monoculture and agroforestry may not be the solution to every problem, it holds promise for both ecological and economical sustainability, if managed judiciously. However, transition to other livelihood systems must occur with minimal degradation of ecosystem services.
