  • Mangroves of the Indus Delta are the world’s fifth largest assemblage, and the largest in the arid zone. Mangroves of Indus delta (PQA) provide immense benefits, products and unrecognized regulatory services. Products of Direct Economic Value: Fish, Minerals and food. There are Products of Natural System (intangible) supplies of rich nutrients to support productivity. Coastal communities benefit in a multitude of ways from Mangrove ecosystems. Collectively, these benefits are known as ecosystem services. The ecological role of mangrove ecosystems in the Indus Deltaic area of Port Qasim Authority (PQA) is, economically and socially significant. The Mangroves are well known for their high biological productivity and their consequent importance provided to the coastal community in terms of services and products of direct and indirect value to the adjacent coastal waters. Mangrove Ecosystem services are regularly involved in the provisioning of food and services and the decomposition of organic wastes. They export organic matter, mainly in detritus form of leaf litter to the marine environment, thus providing a highly nutritious food source for themselves and for the Benthic and terrestrial animals found in the mangrove areas, as well as for those in neighboring estuarine and marine ecosystems. Apart from nutrient export, mangroves also contribute to offshore fisheries by acting as nurseries and shelters for many species of commercially important finfish and crustaceans. Degradation of Indus Deltaic mangrove in PQA would destabilize the economic potential and the livelihood of communities’ which include services and benefits offered by the mangrove ecosystem. Rehabilitation and conservation of mangroves ecosystem in PQA is essential for sustained biological productivity in the region.
