Project Summary / Description:

Lighting Lives in Sundarbans: Community-Owned Solar Energy for Climate Resilience

Lighting Lives in Sundarbans is SEED's flagship renewable energy program addressing the dual crisis of energy poverty and climate vulnerability in one of the world's most climate-threatened landscapes. Initiated in 2021 and currently operational across 40 remote villages in the Indian Sundarbans, the project has installed 350 solar street lights, 2,500 home solar systems, and 600 solar domes, directly benefiting 182,397 people across 33,976 households in four coastal blocks of South 24 Parganas, West Bengal.

The Sundarbans—a UNESCO World Heritage mangrove delta—faces existential threats from sea-level rise, intensifying cyclones (Amphan, Yaas, Bulbul), storm surges, and accelerating land erosion. Communities here endure extreme geographic isolation (accessible only by 2-4 hour boat journeys), unreliable or absent grid electricity, and severe economic vulnerability with 44% of the population below the poverty line. Prior to intervention, households depended on hazardous kerosene lamps and expensive diesel generators, creating health risks, economic burdens, and substantial carbon emissions while limiting productive hours and perpetuating cycles of poverty.

Project Innovation and Approach:

The initiative deploys a hybrid decentralized energy model combining grid-connected energy-efficient infrastructure with standalone solar solutions tailored to local contexts. In 34 grid-connected villages, solar street lights and home systems supplement unreliable electricity supply, while in 6 completely off-grid villages of eroding Ghoramara Island, standalone solar units provide the first-ever reliable nighttime illumination. Solar domes deliver passive daylight technology, eliminating daytime electricity consumption through tubular skylight systems.

Unlike conventional top-down solar deployments that collapse from lack of local ownership, this project pioneers community-custodian governance. We have trained 270 community members—predominantly women and youth—in solar operations, maintenance, and minor repairs, creating a sustainable local workforce independent of external technical support. This capacity-building ensures long-term functionality while generating skilled employment opportunities in the renewable energy sector.

Implementation Through Partnership:

Implemented in partnership with Signify Innovations India Ltd., the project integrates corporate CSR resources with SEED's 29 years of grassroots expertise in climate-vulnerable regions. Our participatory approach involves extensive pre-implementation consultations with Gram Panchayats (village councils), formation of Solar User Groups (SUGs) for community governance, site selection through village-level meetings with residents and Self-Help Groups, and transparent documentation displayed on community notice boards to ensure social license and local ownership.

Transformative Multi-Dimensional Impact:

Climate Mitigation: The project prevents approximately 330-370 tonnes CO₂ emissions annually through displacement of kerosene (80% reduction across households), diesel generators, and coal-based grid electricity. Over the 15-20 year operational lifespan of installed infrastructure, cumulative emissions avoided will exceed 6,000 tonnes CO₂-equivalent.

Climate Adaptation: In a region experiencing 60% reduction in human-wildlife conflict casualties due to improved nighttime visibility, enhanced disaster preparedness through illuminated evacuation routes and emergency response capacity, and strengthened community resilience against cyclones and flooding impacts, lighting infrastructure serves as critical adaptation infrastructure.

Economic Empowerment: Documented impacts include 35% average income increase for local traders and vendors through extended business hours (2.5 additional hours daily), 60% reduction in household energy costs (average ₹1,200 annual savings per household redirected to food, education, healthcare), establishment of 84 new evening businesses in 2025 (tea stalls, food vendors, small shops), and improved fishing efficiency with illuminated ghats enabling safe early-morning and late-evening operations.

Social Transformation: The project has catalyzed 84% improvement in women's evening mobility and safety perceptions, 35% increase in children's study time (2.3 additional hours daily), 45% increase in girls' attendance at evening tuition classes, 67% reduction in reported crimes (theft, harassment, vandalism), and 89% increase in community evening gatherings, cultural programs, and SHG meetings, revitalizing social cohesion.

Health and Safety: Communities report 91% of parents now allowing children evening outdoor activities, 45% reduction in delays seeking emergency medical care at night, elimination of respiratory health risks from indoor kerosene combustion, and significantly reduced accident rates on illuminated pathways.

Scaling Vision and Sustainability:

Building on demonstrated success validated through independent impact assessment by the Institute of Development Studies Kolkata (2024), SEED seeks to scale this proven model to 150 villages across the entire coastal Sundarbans archipelago by 2030, reaching 680,000+ beneficiaries. The sustainability model rests on four pillars: economic sustainability through Solar User Group governance and community maintenance fees, technical sustainability via 500+ trained local technicians at scale, social sustainability anchored in women's leadership and community ownership, and environmental sustainability through climate-resilient equipment design for high-salinity, cyclone-prone conditions.

The project demonstrates that even in the most resource-constrained and environmentally challenging settings, community-led clean energy interventions can deliver transformative impacts across climate mitigation, adaptation, and socio-economic development—creating a replicable model for the 4.5+ million people inhabiting climate-vulnerable coastal regions globally.

How Project Affects Greenhouse Gas (GHG) Emissions:

['Replaces/avoids GHGs (e.g., projects that replace sources of GHGs, such as the burning of fossil fuels for electricity, heat, transport, or other energy uses)', 'Reduces GHGs (e.g., projects that reduce sources of GHGs, such as through efficiency or other changes in consumption)', 'Removes/stores GHGs (e.g., projects that capture, sequester, or otherwise enhance the "sinks" that accumulate and store GHGs)']

Impact on Underrepresented Groups:

Lighting Lives in Sundarbans is designed around communities that are both underrepresented in the climate movement and disproportionately impacted by climate change. The Sundarbans’ island populations face recurrent cyclones, flooding, salinity intrusion and land erosion, which have triggered large-scale distress migration of men in search of work. As a result, many households are now women-led, carrying the burden of livelihoods, caregiving and disaster preparedness with limited access to energy and resources.

The project directly empowers these climate-vulnerable and women-led households by prioritizing off and low grid islands where energy poverty compounds climate risk. Decentralized solar lighting improves safety, mobility, and income-generating opportunities for women, particularly after dark, while reducing dependence on kerosene and diesel. Women are intentionally trained as solar caretakers and  technicians with a minimum 40% representation in local governance and maintenance structures.

Youth and local volunteers are engaged in system monitoring, awareness, and emergency response, building long-term community capacity. Within SEED, women and local professionals are strongly represented across field teams and community institutions. By embedding renewable energy in community-owned, women-inclusive systems, the project shifts climate action toward those most affected; transforming passive vulnerability into local leadership and resilience.
