Zuiderzee Works Zuiderzee Works The Zuiderzee Works () is a man-made system of dams and dikes, land reclamation and water drainage work, in total the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders.

Indus River Delta-Arabian Sea mangroves spills are another hazard. Most of the Indus Delta mangroves have been cleared for firewood and to create grazing land but some remains in three protected areas: Marho Kotri, Cut Munarki Chach Wildlife Sanctuaries and Mirpur Sakro Game Reserve. The World Wildlife Fund assesses the status of the mangrove habitat as being critical or endangered. In projects started in 1985, the Sindh Forest Department has been in the forefront of replanting and restoring mangrove areas in the delta, with support from the International Union for Conservation of Nature, the United Nations Environmental Programme, UNESCO and the World Bank.
