The purpose of the excursion was that we would understand ecosystem structure and be able to make observations and investigations that are important to an ecosystem and interpret them.
While the findings and conclusions of the original study were confirmed, the participants were able to come toconclusions regarding additional factors driving ecosystem structure at seamounts.
It also noted that the goals of the management plan for the Clarion-ClippertonZone included the maintenance of regional biodiversity, ecosystem structure and ecosystem function, together with the application of the principles of integrated ecosystem-based management.
Some of these compounds are highly specific in their toxicity(e.g. TBTs mostly affect molluscs), but by removing specific groups of organisms they disturb food webs anddisrupt ecosystem structure.
(b) Apply internationally accepted conservation management tools in order tomaintain biodiversity and ecosystem structure and function across the Clarion-Clipperton Zone;
Significant adverse impacts are those that compromise ecosystem integrity(i.e., ecosystem structure or function) in a manner that:(a) impairs the ability of affected populations to replace themselves;(b) degrades the long-term natural productivity of habitats; or(c) causes, on more than a temporary basis, significant loss of species richness, habitat or community types.
The workshop identified a number of critical issues that need to be addressed in order toachieve the objective of maintaining the biodiversity, ecosystem structure and ecosystem function in that region.
It noted that by providing a regional environmental baseline anda better understanding of the ecosystem structures and functions in the representative network of areas of particular environmental interest, the proposed environmental management plan for the Clarion-Clipperton Zone might assist contractors in fulfilling their obligations with respect to the evaluation of impact assessments of their activities and the establishment of preservation and impact reference zones.
(b) Encouraging and, where appropriate, supporting and initiating scientific research projects and programmes to enhance knowledge andunderstanding of the ecosystem structures and functions in the areas of particular environmental interest.
Although some marine organisms may also benefit from ocean acidification, even positive effects on one species can have a disruptive impact on food chains, community dynamics,biodiversity and ecosystem structure and function.
The chapter will assess levels of land degradation with regard to the type,extent and severity of changes in both biodiversity and ecosystem structure and functioning in different biomes and under different land-use and management systems.
The vision of the Authority is to facilitate mining while minimizing as far as practically possible the impact of seabed mining activities,and preserving and conserving marine biodiversity and ecosystem structure and function in the Clarion-Clipperton Zone.
The concept is generally associated with management based on the" best understanding of the ecological interactions andprocesses necessary to sustain ecosystem structure and function" .56 A number of related terms in use include an ecosystem-based approach, ecosystem management approach, integrated ecosystem management, 57 ecosystem considerations.
Best-practice management of damaging human activities in the marine environment generally involves the use of spatial management tools, including the protection of areas thought to be representative ofthe full range of habitats, biodiversity and ecosystem structure and function within the management area.
Ecosystem-based management” including“more risk-averse and precautionary management”,where“given prevailing uncertainty regarding ecosystem structure, function, and inter-specific interactions, precaution demands an ecosystem rather than single-species approach to management”.
The environmental management plan for the Clarion-Clipperton Fracture Zone, adopted at the seventeenth session of the International Seabed Authority,includes the maintenance of regional biodiversity, ecosystem structure and ecosystem function, together with the application of integrated ecosystem-based management.
Until then, the representative approach described here provides the best way of capturing those values in undisturbed areas in order to preserve andconserve marine biodiversity and ecosystem structure and function in the context of seabed nodule mining activities based on the best available scientific information.
Priority issues in the region include: unsustainable exploitation of fish and other living resources, decline in landings of commercial species, habitat loss and degradation, eutrophication,change in ecosystem structure and function, and impacts from land-based activities, such as large dams and land reclamation.
Guideline 3 The preservation reference area system is designed with the following conservation goals within the management area(the Clarion-Clipperton Zone):(a) to preserve representative and unique marine habitats;(b)to preserve and conserve marine biodiversity and ecosystem structure and function; and(c) to facilitate the management of mining activities to maintain sustainable, intact and healthy marine ecosystems. .
The Ad Hoc Technical Expert Group on Marine and Coastal Protected Areas of the Convention on Biological Diversity recognized many benefits of such areas relating to both conservation and the sustainableuse of biological diversity, including protecting ecosystem structure, functioning and beauty; allowing recovery from past damage; improving fishery yields; and providing social and economic benefits to local communities and nations.
A workshop held in 2007 recommended that an ecologically and biogeographically reasonable approach to the design of a spatial management plan would be to divide the Clarion-Clipperton Zone into three east-west andthree north-south strata for conservation management because of the strong productivity-driven gradients in ecosystem structure and function. That stratification yields nine distinct subregions within the Zone, each requiring the designation of an area of particular environmental interest.
