Wetland Activities

Wetlands are one of the world’s most productive ecosystems. Wetlands is an areas of land saturated by water that could be fresh, brackish, or salt, and they make up around 6% of the earth’s surface. However, this percentage decreases due to deforestation and the need for land. These ecosystems have a rich biodiversity, for instance, in Sri Lanka, 30% of inland vertebrates depend on wetlands.

Sri Lanka being a tropical country is blessed with a wide array of wetlands and has three main types according to the Ramsar definition:

  • Inland natural freshwater wetlands
  •  Marine and saltwater wetlands
  • Man-made wetlands, such as tanks and reservoirs.

Wetlands are crucial parts of the natural environment and provide many ecosystem services: they act as a filter by absorbing contaminants in runoff, such as fertilizer, and keeping them from entering lakes and rivers as the pollutants are held in place by the roots of wetland plants, which also delay and suspend chemicals that are attached to soil particles. Aside from this, they act as natural flood prevention by storing water during periods of heavy rainfall. Wetlands along the coast, such as mangroves and salt marshes, operate as natural stors, wave, and erosion buffers. They aid with the protection of coastlines from the effects of storms, cyclones, and increasing sea levels, hence protecting coastal residents and infrastructure.

Wetlands also greatly benefit humans through the fishing industry: Two-thirds of all fish that we consume worldwide live at least some of their lives in wetlands. Sri Lanka is unique for using man-made wetlands to provide water for agricultural purposes and domestic use, a practice dating back to 300 BC. Additionally, wetlands are effective carbon sinks, absorbing large volumes of CO2 from the atmosphere. They help to mitigate climate change by lowering greenhouse gas emissions and stabilizing the global carbon cycle by sequestering carbon. As wetlands are at risk due to deforestation and other human activity, wetland protection is a vital necessity.

These remarkable ecosystems provide numerous ecological, economic, and social benefits. It is imperative to protect these valuable environments and the delicate harmony they provide and take decisive action to safeguard them from future degradation and loss by raising awareness, implementing conservation methods, and supporting sustainable activities.
