Table 1. An Ecosystem approach requires new thinking about how marine
ecosystems are defined, and
how problems and solutions are framed. (Adopted and modified from Fluharty,
2000; Holling, 1996;
Gonzalez, 1996).
- Management scales are nested in a multiple spatial and temporal
application of five module multi-sectoral
suites of indicators ranging in scale from LME’s for the ocean
environment into watersheds.
- Ecosystem delineations must be scientifically
defensible (e.g. best available science) and administratively
practical.
- LME boundaries are based on ecological criteria such as ecosystem
health, resilience, and stability.
- Ecosystem categories of threat, level
of threat, and “distance” from
desired restoration condition can be
combined to rank ecosystems at risk. Ranks (should be based on a review
of quantitative information by a
scientific panel with stakeholder participation. Ranks (from e.g. comparative
risk assessment(s)) can be
employed to plan and prioritize management regulatory agency action for
ecosystems at various levels of
present and future risk.
- The United Nations Food and Agricultural Organization
(FAO) provides a salient perspective definition of
an “ecosystem approach to fisheries” that it “strives
to balance diverse societal objectives, by taking into
account the knowledge and uncertainties about biotic, abiotic and human
components of ecosystems and
their interactions and applying an integrated approach to fisheries within
ecologically meaningful
boundaries” (see: http://www.fao.org/docrep/).
- Holling (1996) advocates
that “at a minimum, the goal of ecosystem
management is understanding
to reduce uncertainties, action to maintain or restore resilience (i.e.,
the ability of a system to absorb
change and variation without flipping into a different state where the
variables and processes controlling
structure and behavior suddenly change) as insurance for the unknown,
and creation of incentives for
maintaining sustainable systems”.
- NOAA’s strategic vision
stated in New Priorities for the 21st Century places its first mission
goal to “protect, restore, and manage the use of coastal and
ocean resources through ecosystem-based
management.” Its objectives under this mission goal are economically,
scientifically and socially
interdependent.
- Ecosystem-based Management: U.S. ocean and coastal
resources should be managed to reflect the
relationships among all ecosystem components, including humans and
nonhuman species and the
environments in which they live. Applying this principle will require
defining relevant geographic
management areas based on ecosystem, rather than political, boundaries.
