I
Impact assessmentThe evaluation of ecological effects to determine their impact on human needs, environmental, social and economic (see also “environmental impact assessment” above).
Impermeable groyne A groyne
constructed such that sand cannot pass through the structure (but sand may
still move over or around it).
IndicatorA measurement that can be used to assess the condition, status or trends of an ecological resource. The term is widely used in water resources management programs, but has many different interpretations. It is preferable in risk assessment to avoid using the term indicator and instead use the more specific terms measure of effect, measure of exposure, and assessment endpoint, as appropriate.
Infrastructure Usually the publicly constructed support system for a community including roads, electricity, communications, water, sewage, etc.
Initial Environmental Evaluation IEE The initial environmental assessment of a development activity at the project feasibility phase in order to provide early identification of potential environmental impacts and to determine whether a full EIA will be necessary.
Inshore (zone) In beach terminology, the
zone of variable width extending from the low water line through the breaker
zone.
Institutional Integration The process of bringing together separate
functions of government at different levels together with other stakeholders to
provide a unified approach to interventions in the managed area.
Integrated Coastal Management (ICM) The management of sectoral
components (e.g., fisheries, forestry, agriculture, tourism, urban development)
as part of a functional whole (a holistic approach to management). In ICM the
focus is on the users of natural resources, not on the stock perse of these resources. Frequently used synonyms for ICM are integrated
coastal area management (ICAM) and integrated coastal zone management (ICZM).
Integrated Coastal Zone Management ICZMIntegrated coastal zone management (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. See also: Coastal Zone Management.
Integrated regional development planningLarge-scale development planning for a region which incorporates all salient planning parameters including economic, socioeconomic, environmental and others.
Intertidal zoneThe transition zone between the sea and the land, often defined as the zone that lies between mean higher high water and mean lower low water lines.
Inundation AreaArea flooded with water by the tsunami.
Isobath A contour line
connecting points of equal water depths on a chart.
IsostaticLocal or regional changes in the ground surface elevation,
resulting in land subsidence or uplift.
Issue analysisThe exploration, definition, and evaluation of the basic resource management issues to be faced in an ICZM program
Iterative ProcessA process involving the continual refinement of goals and objectives as new knowledge and questions generated by investigation and analysis feed back into the investigative cycle. See also Process Approach
