The best examples of mangrove forests on the west coast of India are found here, but mangroves are felled for firewood and corals are used as raw materials for a local cement plant.However, the state of the Indus Delta in Pakistan shows that problems similar to those of the Wadden Bay are emerging in the Indian Ocean.The survey found that “industrial and agricultural pollution seriously threatens the productivity of some estuaries in the Indus Delta.Its waters are already contaminated with agricultural chemicals, and the construction of a steel mill near Phitti Cove could negatively impact nearby prawn fry areas.Moreover, a large area of ​​mangrove forest will need to be drained or backfilled during the construction of a new port for Karachi.Destruction of fishing grounds can create enormous difficulties. Phitti and Koryangi bays produce more than 800 tons of shrimp annually.


The Indus Delta is one of Pakistan's most important fishing grounds, the largest source of foreign exchange, employing thousands of local residents.The situation in the Indus Delta is similar to that in the Wadden Strait, with only one but significant difference.Scientific and administrative authorities concerned about the fate of the Wadden Sea have the capacity to predict the impact of pollution and the construction of ports and industrial facilities, and therefore they can prevent or at least reduce these impacts.Pakistani administrators do not have these options.The Diari River, which flows into Mayora Bay, where the port of Karachi is located, carries wastewater from more than 100 industrial enterprises, but the Fisheries Department has neither the money nor the technical means to carry out the necessary research.Habitat degradation and destruction are now significant challenges for the United States fisheries, as these processes result in an estimated $ 86 million loss each year.87% of the total economic damage to the east coast of the United States is in two regions: the Gulf of Mexico, from the southernthe tip of Florida to the Mexican border; and the mid-Atlantic coast of the United States — from Long Island, New York, to the Chesapeake Bay.In the Gulf of Mexico, the main problems are drainage and backfilling of coastal wetlands, as well as contamination of oyster cans by sewage, which poses a risk to human health.As calculations have shown that 97% of the commercial species in the Gulf of Mexico depend on estuaries, the destruction of wetlands can lead to catastrophic consequences.It is estimated that for every 0.4 ha of “reclaimed” or otherwise destroyed estuary, almost 1000 kg of fish are lost on the continental shelf.In the estuaries of the Gulf of Mexico, 67,000 hectares of economically important habitat are destroyed every year, accounting for 5.5% of their total area and almost 3% of the region's coastal wetlands.
