Integrated coastal zone management (ICZM) or Integrated coastal management (ICM) is a process for the management of the coast using an integrated approach, regarding all aspects of the coastal zone, including geographical and political boundaries, in an attempt to achieve sustainability This concept was born in 1992 during the Earth Summit of Rio de Janeiro. The specifics regarding ICZM is set out in the proceedings of the summit within Agenda 21, ''Chapter 17''. The European Commission defines the ICZM as follows:- ICZM is a dynamic, multidisciplinary and iterative process to promote sustainable management of coastal zones. It covers the full cycle of information collection, planning (in its broadest sense), decision making, management and monitoring of implementation. ICZM uses the informed participation and cooperation of all stakeholders to assess the societal goals in a given coastal area, and to take actions towards meeting these objectives. ICZM seeks, over the long-term, to balance environmental, economic, social, cultural and recreational objectives, all within the limits set by natural dynamics. 'Integrated' in ICZM refers to the integration of objectives and also to the integration of the many instruments needed to meet these objectives. It means integration of all relevant policy areas, sectors, and levels of administration. It means integration of the terrestrial and marine components of the target territory, in both time and space. To further understand the idea of ICZM several aspects can be defined and further explained. The coastal zone, the concept of sustainability and the term integration all within a coastal management context can be individually defined, while the expectations and framework of ICZM can be further explained. This entry uses the example of the New Zealand national framework to illustrate ICZM. ==Defining the Coastal Zone== Defining the Coastal zone is of particular importance to the idea of ICZM. But the fuzziness of borders due to the dynamic nature of the coast makes it difficult to clearly define. Most simply the coast can be thought of as an area of interaction between the land and the ocean. Ketchum (1972)〔KETCHUM, B. H. 1972. The water's edge: critical problems of the coastal zone. In: Coastal Zone Workshop, 22 May-3 June 1972 Woods Hole, Massachusetts. Cambridge: MIT Press.〕 defined the area as: The band of dry land and adjacent ocean space (water and submerged land) in which terrestrial processes and land uses directly affect oceanic processes and uses, and vice versa. Issues arise with the diversity of features present on the coast and the spatial scales of the interacting systems. Coasts being dynamic in nature are influenced differently all around the world. Influences such as river systems, may reach far inland increasing the complexity and scale of the zone. These issues make it difficult to clearly identify hinterlands and subscribe any subsequent management. Whilst acknowledging a physical coastal zone, the inclusion of ecosystems, resources and human activity within the zone is important. It is the human activities that warrant management. These activities are responsible for disrupting the natural coastal systems. To add to the complexity of this zone, administrative boundaries use arbitrary lines that dissect the zone, often leading to fragmented management. This sectored approach focuses on specific activities such as land use and fisheries, often leading to adverse effects in another sector. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Integrated coastal zone management」の詳細全文を読む スポンサード リンク
