As global climate negotiators are in action at COP29, a new study sheds light on the alarming consequences of climate change on Bangladesh's coastal ecosystems, with a sharp focus on the fragile Manpura Island. Conducted by Joy Bhowmik, Haseeb Md Irfanullah, Samiya Ahmed Selim and Mohammad Budrudzaman, the research reveals the socio-economic and non-economic losses experienced by communities on the island due to slow-onset climate phenomena. The findings call for urgent, evidence-based policymaking to mitigate these damages and foster resilience among affected populations. Ecosystem Erosion and Its Toll The study, conducted between 2020 and 2023 and published under a Creative Commons licence, reveals the severe impacts of salinity intrusion and sea-level rise on biodiversity and ecosystem services. Unlike human systems, ecosystems lack the adaptive capacity to cope with such changes, resulting in devastating consequences for communities reliant on them. Economic assessments show that households on Manpura Island incur annual losses of $28 to $419 (approximately Tk 3,000 to Tk 46,000), with rice, fish, livestock, and crops among the most affected resources. These losses were further aggravated by Cyclone Yaas, which inflicted additional damage on already vulnerable livelihoods. The study, however, goes beyond monetary metrics to highlight the intangible yet profound non-economic losses (NELD) suffered by the islanders.

Call for Adaptive Measures The researchers emphasise the importance of strengthening human capital as a cornerstone of ecosystem-based adaptation. They advocate for investment in education, skills training, and livelihood diversification to mitigate future losses and enhance resilience. One of the study’s key recommendations is the development of web-based ICT platforms for documenting losses and damages in real time. Such systems would provide policymakers with actionable data, fostering transparency and accountability in climate interventions. Manpura: A Global Microcosm Manpura Island serves as a stark representation of the challenges faced by countless vulnerable communities across the globe. Its plight underscores the necessity of incorporating non-economic losses into climate negotiations—an area often overlooked in mainstream policies. “The value of ecosystems goes beyond material goods,” the authors note, urging policymakers to adopt a holistic approach that recognises the cultural, emotional, and psychological dimensions of ecosystem services. Erosion of Land and Heritage Over the decades, Manpura has experienced significant ecological losses: Land Loss: The island’s area has reduced from 148 square kilometres in 1973 to just 114 square kilometres by 2010, with significant erosion along its northern and northwestern shores. Soil Erosion: Heavy rainfall, cyclones, storm surges, and rising sea levels have stripped away fertile topsoil, threatening agricultural productivity and livelihoods. Crop Loss: Agricultural land has decreased by 38% since 1990 due to morphological changes and human activities. Cultural Erosion: The island’s intangible losses, such as declining health, emotional distress, and a weakened sense of identity, have further alienated its inhabitants from their heritage. Bangladesh’s Role at COP29 As Bangladesh continues to champion the interests of climate-vulnerable nations, the plight of Manpura Island serves as a sobering reminder of what is at stake. The research by Bhowmik and his colleagues is a clarion call for urgent action, highlighting the need for solutions rooted in local realities.

As the world faces an intensifying climate crisis, it is imperative for governments and international bodies to prioritise the needs of communities on the frontlines. Manpura’s story is not just a warning but a call to action for a sustainable, equitable future—for Bangladesh and beyond, according to the researchers.

Manpura Before 2009, Manpura was just another island on the southern edge of the Meghna River in the Bay of Bengal. Thanks to Giasuddin Selim’s Magnum Opus “Manpura” movie, the island came into the limelight. Ever since the blockbuster, there has been a growing interest in Manpura as a new travel destination.  Here’s everything you need to know about the Manpura island, how to get there, what are the attractions, and many more.  Where is Manpura island?  Manpura island is situated in the northern Bay of Bengal. It borders the exit of the Meghna River into the bay. The island is formally known as Manpura upazila under the Bhola district. It is surrounded by the two of the biggest islands of Bangladesh – Bhola and Hatia.  Read more: Tinap Saitar Waterfall Travel Guide: Visit a pristine natural fountain in Bandarban
