Community-Based Soil and Water Conservation for Sustainable Agriculture in Lateritic South Bengal, India

ABSTRACT: Sustainable agriculture is becoming increasingly essential in regions facing soil erosion, water scarcity, and declining productivity. Combining traditional soil and water conservation methods with biophysical techniques and community-based watershed management offers effective solutions to these challenges. This research investigates how community-driven watershed management methods impact soil conservation, water management, and agricultural productivity, using case studies from the lateritic region of South Bengal. This area faces significant issues, including soil erosion, unpredictable rainfall, and water scarcity, with local communities adopting traditional and modern watershed practices to enhance agricultural sustainability and output. The study evaluates the effectiveness of these techniques through two case studies, focusing on soil conservation methods such as terracing, check dams, water-harvesting structures, and vegetation cover, as well as water management efforts such as rainwater harvesting and groundwater recharge. Using field surveys, interviews with community members, and crop yield data, the research examines the relationship between these practices and improvements in soil quality, water availability, and crop productivity. Qualitative evidence from case studies suggests that community-led initiatives have reduced erosion risk, improved water availability, and enhanced agricultural production in some locations, especially when fully integrated into local farming systems. Additionally, the study highlights the vital role of community participation, local knowledge, and cooperative governance in ensuring the success and sustainability of these practices. The results from two case studies in different districts of the lateritic region of South Bengal emphasise the importance of incorporating community-driven strategies into watershed management to achieve long-term soil conservation, efficient water use, and increased agricultural yields. The findings suggest that merging traditional and modern techniques provides a resilient, sustainable approach to agricultural management, and expanding these methods can help address challenges related to climate change, food security, and rural livelihoods in similar regions. However, as the study is based primarily on farmer perceptions, case-study evidence, and existing records rather than direct biophysical measurements (e.g., soil loss, groundwater dynamics, or pre- and post-intervention crop yields), the findings should be interpreted as indicative rather than causal and should be further validated through field-based empirical assessments.
