The island is situated at approximately latitude 22º1ánd 22º6´N and longitude 90º58ánd 91º3´E, and experiences a tropical coastal climate influenced by monsoon seasons and periodic cyclones
Economic and Ecological Value of Bees in Nijhum Dwip
Bees are integral to the economic and ecological fabric of Nijhum Dwip. The beekeeping industry serves as a cornerstone of local livelihoods. Honey production from species like Apis dorsata and Apis cerana contributes approximately $10,000 annually to household incomes. Local honey, derived from mangrove flora such as Keora (Sonneratia apetala), holds premium market potential both nationally and internationally, with estimates suggesting honey exports could exceed $10 million annually if effectively scaled. Ecologically, bees provide crucial pollination services that enhance crop yields by up to 30%, thereby contributing to food security and agricultural resilience. Their role in pollinating mangrove species supports biodiversity and sustains coastal ecosystems, which are vital for coastal protection and fisheries—key resources for local communities. Additionally, bees facilitate the regeneration of mangrove trees, contributing to erosion control and climate change mitigation. Healthy mangrove ecosystems are significant carbon sinks, playing a critical role in global climate regulation.
Bee and Bee Plant Diversity on Nijhum Dwip
Nijhum Dwip is home to a diverse array of bee species essential for pollination and ecosystem health. Key species include: Apis dorsata (Giant Honey Bee): Predominantly found in the wild, crucial for pollinating mangrove habitats and producing high-quality honey; Apis cerana (Asian Honey Bee): Commonly domesticated, this species plays a vital role in agricultural pollination, and Stingless Bees (Tetragonula spp.): Though not honey producers, these bees significantly contribute to the pollination of smaller flowering plants, maintaining ecological balance. The presence of these diverse species underscores the importance of pollinators for local biodiversity and food security.
The flora of Nijhum Dwip supports a rich variety of bee forage plants essential for sustaining local bee populations. Keora (Sonneratia apetala): A prominent mangrove species that flowers during the dry season, providing crucial nectar and pollen; Gewa (Excoecaria agallocha): Another vital mangrove, supporting bee populations and contributing to overall ecosystem resilience, and Agricultural Crops: Seasonal crops such as mustard, sunflowers, and watermelon benefit significantly from bee pollination, leading to improved agricultural productivity.
This diversity in flowering plants is vital for the survival of both wild and domesticated bees, fostering resilience against environmental fluctuations.
Bee-Based Alternative Livelihoods and Resilience
Beekeeping has emerged as a sustainable livelihood option for the communities of Nijhum Dwip, particularly in the face of climate vulnerability and environmental degradation. Income Diversification: Beekeeping offers a low-input, high-output alternative to traditional livelihoods, providing economic stability as agricultural productivity declines due to salinity intrusion and coastal erosion. Empowerment of Marginalized Groups: Initiatives in small-scale beekeeping empower women and marginalized communities, promoting gender equality and enhancing economic opportunities. Sustainability: Sustainable beekeeping practices reduce reliance on harmful activities such as overfishing and deforestation, supporting local economies and opening markets for organic honey products.
Bee-Plant Interactions and Climate Change Mitigation
Bees play a pivotal role in maintaining ecological integrity through their pollination services. Pollination Services: As keystone pollinators, bees facilitate the reproduction of mangroves and agricultural crops, enhancing biodiversity and ecosystem stability. Mangrove Pollination: The pollination of mangroves by bees is critical for coastal protection and ecosystem regeneration, indirectly safeguarding communities from climate-related hazards.
Bees contribute to climate change mitigation in several key ways. Carbon Sequestration: By supporting the health and growth of mangrove ecosystems, bees enhance their capacity to sequester carbon. Mangroves can store up to four times more carbon per hectare than tropical rainforests (WWF, 2020). Ecosystem Resilience: The interconnectedness of bee and plant species enhances the resilience of ecosystems, enabling them to adapt to changing environmental conditions and mitigating the impacts of climate change.
Comparative Perspectives on Bees and Climate Change
On a national level, Bangladesh recognizes the importance of pollinators for food security and biodiversity conservation. The National Biodiversity Strategy and Action Plan (2016) emphasizes the need to protect pollinators, particularly in vulnerable areas like Nijhum Dwip. Globally, the FAO estimates that over 75% of food crops depend on pollination, making the decline in bee populations a serious threat to global food security. Nijhum Dwip exemplifies community-led efforts to promote sustainable beekeeping and mangrove restoration, aligning with international conservation strategies and providing a model for other regions.
