Agroforestry systems and their impact on livelihood improvement of tribal farmers in a tropical moist deciduous forest in Bangladesh

Abstract

This study investigates the composition of and preferences by farmers related to trees and crops planted in agroforestry systems, and their role on the livelihood of tribal farmers in a tropical moist deciduous forest in Tangail, Bangladesh. Data was collected from 150 tribal farmers practicing different types of agroforestry systems in Madhupur Sal forest, using a mixed-method strategy that included a survey, focus group discussion, key informant interviews, and direct observation. According to the results, tribal farmers used a total of 22 trees and 33 crop species in their existing agroforestry systems, indicating a rich composition and high diversity. Acacia auriculiformis was the most common tree species (with 82% of farmers possessing this species), followed by Mangifera indica (75%), Acacia sp. (73%), and Gmelina arborea (54%). Interviews revealed that agroforestry systems have provided numerous benefits and greatly enhanced farmers’ livelihoods through better access to food, timber, fodder, and fuelwood and greater access to livelihood capitals (except social capital). Though agroforestry practices increase species diversity, provide economic returns, and help farmers maintain their livelihoods, tribal farmers face several constraints including bureaucracy and a lack of alternative market facilities. Our study can be of interest for future policy interventions focusing on sustainable reforestation practices, how to solve the problems faced by the farmers, and livelihood improvement in Bangladesh.
