Bangladesh’s economic growth strategy hinges on bolstering trade, enhancing competitive exports, fortifying infrastructure, and fostering productive employment. Despite this, the vital role played by the Sundarbans mangrove ecosystems in achieving these goals is often overlooked in economic policy dialogues.
The Sundarbans, recognized as the world’s largest continuous mangrove forest and a UNESCO World Heritage Site, serves as both an ecological gem and a strategic economic resource. However, its resilience is facing mounting challenges. A recent study in Communications Earth & Environment revealed that approximately 10-15% of the Sundarbans (equivalent to 610 to 990 square kilometers) has experienced a decline in its ability to rebound from climate stress over the last 25 years. This raises concerns about the long-term sustainability of the ecosystem services crucial for Bangladesh’s coastal economy.
The Sundarbans play a crucial role in protecting coastal infrastructure and commercial activities from cyclones and storm surges, sustaining fisheries that contribute to food security and export revenues, generating around $53 million annually through tourism, and supporting the livelihoods of millions of coastal residents. Recognizing mangroves as valuable natural capital, rather than just a conservation resource, is imperative for Bangladesh’s enduring economic strength, competitiveness, and sustainable development.
While the visible economic benefits from fisheries, honey production, timber, and tourism are significant, the true value of mangroves lies in the economic losses they avert. By mitigating storm surges, curbing coastal erosion, and acting as a buffer against cyclones, the Sundarbans shield ports, embankments, transport routes, agricultural lands, and coastal businesses that form the backbone of Bangladesh’s economy. Studies show that healthy mangrove belts can slash storm-related damages by 50%, reducing disaster losses, alleviating strain on public finances, ensuring business continuity, and boosting investor confidence.
Incorporating natural capital into development planning, as many countries are doing through the United Nations’ System of Environmental-Economic Accounting (SEEA), can provide governments with a better understanding of the economic contributions of forests, wetlands, and mangroves. The Bangladesh Bureau of Statistics (BBS) is currently developing the country’s first Natural Resource Accounts (NRA), marking a significant stride towards linking environmental assets with economic decision-making. By quantifying the economic value of natural assets like the Sundarbans and aligning them with economic activities, these accounts can furnish a robust foundation for climate-resilient fiscal planning and sustainable land-use decisions.
Furthermore, mangroves offer a promising avenue for Bangladesh in the emerging blue-carbon economy. Mangroves store vast amounts of carbon, presenting an opportunity to generate verified blue carbon credits for trading in international carbon markets. The revenue from these markets could fund ecosystem restoration, enhance coastal resilience, support local livelihoods, and attract private investments through public-private partnerships.
Despite these opportunities, Bangladesh is currently undervaluing its mangrove ecosystems and depleting natural capital due to weak governance and unplanned coastal development. The destruction of mangrove forests in Sonadia and the degradation of mangroves in Moheshkhali underscore the high economic cost of neglecting mangroves as productive assets. Encroachments for shrimp farming, salt cultivation, and unplanned development have eroded thousands of acres of mangroves, weakening coastal defenses against cyclones and erosion, diminishing ecotourism potential, and jeopardizing coastal livelihoods.
As Bangladesh progresses towards upper-middle-income status, preserving essential natural assets like mangroves is crucial for sustainable economic activity. Prioritizing mangroves as strategic economic infrastructure and integrating their value into national development planning and infrastructure assessments should be a key national agenda. Additionally, establishing a credible blue carbon market supported by transparent governance and equitable benefit-sharing, while focusing on mangrove restoration alongside other key infrastructures, can attract private investments through green finance.
The Sundarbans already yields significant economic benefits through fisheries, tourism, livelihood support, coastal protection, and blue carbon opportunities. Viewing it as productive natural capital, rather than just a protected forest, can boost productivity, safeguard trade and infrastructure, attract climate finance, and pave the way for a more competitive, resilient, and sustainable economy.
