Treat the new wetlands report as a red flag

Preserving and restoring natural infrastructure can reduce disaster risk

If there is one beautiful wetland that can be called the jewel of India’s natural heritage, it is the Loktak Lake in Manipur. It is well known for phumdis (heterogeneous mass of vegetation) floating over it and the Keibul Lamjao National Park located on these phumdis is the only floating national park in the world, home to the endangered Sangai and Manipur brown-antlered deer. That’s not all: Loktak’s biological diversity comprises 233 species of aquatic plants and 57 species of water birds. Today, development activities such as hydropower generation, irrigation and drinking water supply are destroying this lake. Unfortunately, such destruction of wetlands is a worldwide phenomenon. According to the Global Wetland Outlook (State of the World’s Wetlands and their Services to People 2018), 35% of wetlands — lakes, rivers, marshes, peatlands, as well as coastal and marine areas such as lagoons, mangroves, and coral reefs — across the world were lost between 1970 and 2015. “We are losing wetlands three times faster than forests,” said Rojas Urrego, head of the Ramsar Convention on Wetlands.

It is important that the Global Wetland Outlook report is treated as a red flag by all governments since they contribute to 75 Sustainable Development Goal indicators. If we specifically take the urban sector, they help in flood control, store excess rainwater, replenish groundwater, supply freshwater, play host to an assemblage of species, and provide cultural and aesthetic value. The 2015 flood in Chennai is just one example of what destruction of wetlands can lead to. Restoring natural infrastructure can help reduce the risk of a disaster. The Netherlands has restored natural floodplains of the Rivers Ijssel, Rhine, Lek and Waal, to reduce the impact of floods. In India, the Coringa Wildlife Project in Andhra Pradesh has revived mangroves, and, according to UNDP calculations, these mangroves have protected at least 75,000 people of Kakinada from cyclones.
