However, the sustainability and resilience of Bangladesh’s haors and wetland ecosystems are threatened by many challenges. Some of these obstacles are:
– Climate change:
Climate change impacts the hydrological cycle and alters the patterns of precipitation, temperature, evaporation, and sea level rise. This can result in more frequent and intense floods and droughts, increased salinity intrusion, decreased water availability and quality, increased erosion and sedimentation, loss of wetland habitats and biodiversity, and heightened community vulnerability to natural disasters.
– Human activities:
Human activities such as agriculture, urbanization, industrialization, infrastructure development, mining, fisheries, and aquaculture have converted, degraded, and fragmented haors and wetlands. This can result in a loss of ecosystem functions and services, a reduction in the productivity and diversity of natural resources, an increase in pollution and contamination, a rise in conflicts over resource use and management, and a decrease in the adaptive capacity of ecosystems and people.
– Institutional constraints:
Institutional constraints, such as a lack of awareness, knowledge, coordination, participation, governance, and policy support, have impeded the effective conservation and management of haors and wetlands. This can result in inadequate recognition of the values and benefits of haors and wetlands, insufficient allocation of resources and incentives for their protection and restoration, weak enforcement of laws and regulations, a lack of stakeholder participation and empowerment, and the absence of haors and wetlands in national development plans and strategies.
