Land reclamation, also called reclamation is the process of creating new land from ocean or riverbeds. A study found land-reclamation projects shrank the number of mangroves in Tubli Bay, off Bahrain's east coast. Industries also flock around coastal areas because of the ease of transportation of goods and equipments. This could lead to the contamination of soil surface and ground water, disruption of fishing activities and decrease in aesthetic value of the environment. The problem is that mangroves provide numerous ecosystem services to the local people while the palms provide no ecosystem service to the people. This estimate was made using Arc GIS [9].
