Drains Clogged, Ecology Imbalanced As Lakes and Forests Disappear
The rapid disappearance of forests, wetlands, and lakes around Dhaka City is creating serious environmental challenges, including clogged drainage systems, frequent waterlogging, and ecological imbalance. Environmentalists warn that unless immediate measures are taken to protect these natural resources, the capital may face even greater environmental and public health crises in the coming years.
Over the past few decades, Dhaka has experienced unprecedented urban expansion. Vast areas of forest land, water bodies, and open spaces have been filled or cleared to make way for residential buildings, roads, shopping complexes, and industrial establishments. As a result, many natural lakes and canals that once served as water reservoirs and drainage channels have either shrunk significantly or disappeared altogether.
Experts point out that forests and wetlands play a crucial role in maintaining ecological balance. Trees absorb carbon dioxide, release oxygen, regulate temperature, and help conserve biodiversity. Lakes and wetlands act as natural drainage basins, storing excess rainwater during heavy downpours and preventing floods. Their disappearance has reduced the city's ability to cope with increasing rainfall and extreme weather events.
One of the most visible consequences of losing lakes and wetlands is the worsening drainage problem. During the monsoon season, many areas of Dhaka remain submerged for hours or even days after moderate rainfall. With natural water retention areas gone, rainwater has nowhere to go except into already overloaded drains and canals. Moreover, construction debris, plastic waste, and illegal encroachments further obstruct drainage networks, causing severe waterlogging across the city.
The ecological impacts are equally alarming. The destruction of forests and water bodies has led to the loss of habitats for birds, fish, and other wildlife. Many native species are gradually disappearing from the region. The reduction of green spaces also contributes to rising temperatures, creating an urban heat island effect that makes city life increasingly uncomfortable.
Environmental scientists stress that preserving existing lakes, canals, and forests is essential for sustainable urban development. They recommend strict enforcement of environmental laws, restoration of encroached water bodies, large-scale tree plantation programs, and improved waste management systems. Public awareness campaigns can also encourage citizens to participate in protecting the environment.
Government agencies, city authorities, and community organizations must work together to address the problem. Sustainable planning should prioritize the conservation of natural ecosystems alongside urban growth. Without such efforts, Dhaka's environmental challenges will continue to intensify.
The disappearance of forests and lakes around Dhaka is more than an environmental issue; it is a threat to the city's future. Protecting these vital natural resources is essential to ensuring efficient drainage, ecological stability, and a healthier living environment for millions of residents.
