The coastal zone comprises only 3% of the earth’s surface and accommodates about 60% of the world’s population, a figure set to increase to 80% by 2050. As a result, 2/3 of those cities in the world, with a population of more than 7.6 billion people are found in coastal areas. Coastal areas have a great ecological value, for recreation and tourism and provide habitat for many endangered species and also are source of 90% of the world's fish catch. When thinking of food demands of the future, one cannot ignore the coastal zone that provides both Paddy and fish. ICID took note of this way back in 2001 and established the Working Group on Sustainable Development of Tidal Areas (WG-SDTA).
The tidal areas can be defined as all those coastal areas where the tidal processes are capable of affecting man's activity or of being influenced by human (on the seaward side about 30m water depth and on the landward side up to the limit of the action of sea). The Working Group reviews the progression of natural wet land conservation and constructed wetland development in tidal areas. It attempts to raise awareness of the increasing risk to tidal areas due to global climate change, stimulate discussion on impacts and mitigation measures, and find a balance between the preservation and development of tidal areas. The Group advocates for enhancement of survey, improvement in design techniques, collect information about the tidal area environment around the world; join the international dialogue and organize international conferences. Based on the work undertaken by the WG-SDTA, ICID has brought out publication titled “Towards Sustainable Development of Tidal Areas: Principles and Experiences” to improve the planning, design and management of irrigation and drainage projects in tidal areas.
