Ecosystem Approach

The ecosystem approach are principles to use the ecosystems with holistic overview. The Convention on Biological Diversity recommended application of the principles of ecosystem approach by Decision V/ 6[1] and agreed the priority on facilitating the implementation of the ecosystem approach as the primary framework for addressing the three objectives of the Convention in a balanced way by Decision VII/11[2].

The ecosystem approach is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way.  This strategy should follow and complement with policies on sustainable development. It is based on appropriate scientific research and traditional knowledge, focuses on levels of biological organization which encompass the essential processes, functions and interactions among organisms and their ecosystems. This document has as objective to does an analyses on ecosystem approach. Fig.1.
 

The following 12 principles are complementary and interlinked.

 

Principle 1: The objectives of management of land, water and living resources are a matter of societal choices.


The ecosystem management has influence on social needs. Different actors of society use ecosystems by their own interest and outlook. They value ecosystems resources by direct use, but they also need to take account their intrinsic values and for the tangible or intangible benefits for humans, in a fair and equitable way.



Principle 2: Management should be decentralized to the lowest appropriate level.


Decentralized systems may lead to greater efficiency, effectiveness and equity. They are essential requirements for good governance.  Management should involve all stakeholders and balance local interests with the wider private and public interest of urban areas.

Principle 3: Ecosystem managers should consider the effects (actual or potential) of their activities on adjacent and other ecosystems.
Managers should take account unpredictable effects on other ecosystems, and possible negative potential impacts.  They need careful consideration and analysis. This may require effective monitoring systems, early warning systems, assessment scenarios and models and local organization, to take rapid decisions and appropriate compromises.
Principle 4: Recognizing potential gains from management, there is usually a need to understand and manage the ecosystem in an economic context.
Any such ecosystem-management programme should:
a. Reduce those market distortions or market failures and externalities, that adversely affect ecosystems and biological diversity;
b. Align incentives to promote land use plans and legal orders to enhance ecosystems and biodiversity conservation and sustainable use;
c. Internalize the costs and benefits in the ecosystem use.
 
The greatest threat to ecosystems and biological diversity lies the land change use without planning land use and legal order, this management and policies not take account natural capacities of ecosystems and safe ecological limits. This often arises through market distortions and externalities, which undervalue natural systems and wild populations and provide perverse incentives and subsidies to favor change land use to lead less diverse systems, affecting their resilience.
Principle 5: Conservation of ecosystem structure and functioning, in order to maintain ecosystem services, should be a priority target of the ecosystem approach.
Ecosystem structure and functioning are needed to give resilience. The economic human activities affect ecosystems and some of them are threatened as coral reef, wetlands, tropical and driest forest, as well as, marine ecosystem production. These results lead to prioritize restoration, improve effectiveness and protected areas management and their connectivity
Principle 6: Ecosystem must be managed within the limits of their functioning.
The ecosystems management should develop on policies that respect limit natural productivity, ecosystem structure, functioning and diversity. The limits to ecosystem functioning may be affected to their goods and services by different degrees with economic and social consequences in the short and long term.
Principle 7: The ecosystem approach should be undertaken at the appropriate spatial and temporal scales.
The ecosystems management should be bounded by spatial and temporal priorities, taking account the Aichi Targets and the National Country Strategy and Action Plan on Biological Diversity (NBSAP)[3] at national and local scales. Boundaries for management will be defined operationally by users, managers, scientists and indigenous and local peoples. Connectivity between areas should be part of sustainable use areas on the framework landscape use planning and legal order.
Principle 8: Recognizing the varying temporal scales and lag-effects that characterize ecosystem processes, objectives for ecosystem management should be set for the long term.
Ecosystem processes are characterized by varying temporal scales and lag-effects. This characteristic should consider on monitoring activities and strategies for sustainable development.
Principle 9: Management must recognize the change is inevitable.
Ecosystems change, including species composition and population abundance, it is part of evolution and their resilience for human activities. Hence, management should adapt to the changes. The ecosystem approach must utilize adaptive management in order to anticipate and cater for such changes and events and should be cautious in making any decision that may foreclose options, but, at the same time, consider mitigating actions to cope with long-term changes such as climate change, pollution and overexploitation.
Principle 10: The ecosystem approach should seek the appropriate balance between, and integration of, conservation and use of biological diversity.
Biological diversity is critical for its intrinsic value, bequest value and existence value.  It plays a key role in providing the ecosystem and other services upon which we all ultimately depend. There is a need for a shift to more flexible situations, where conservation and use are seen in context and the full range of measures is applied in a continuum from strictly protected to sustainable use ecosystems.
Principle 11: The ecosystem approach should consider all forms of relevant information, including scientific and indigenous and local knowledge, innovations and practices.
Information from all sources is critical to arriving at effective ecosystem management strategies. All relevant information from any concerned area should be shared with all stakeholders and actors, taking into account, inter alia, any decision to be taken under Article 8(j) of the Convention on Biological Diversity. Assumptions behind proposed management decisions should be made explicit and checked against available knowledge and views of stakeholders.
Principle 12: The ecosystem approach should involve all relevant sectors of society and scientific disciplines.
The ecosystem management is multivariable, since there are many interaction natural and human, with many implications, and therefore should involve. This lead to the necessary expertise and stakeholders at the local, national, regional and international level.

Conclusion
 The ecosystem approach is a strategic ecosystem management based on ecological limits at three scales national, subnational and local, on the framework of maintenance of ecosystem structure and functions.
 
The ecosystem approach promotes and improves good governance[4] with landscape overview, giving balance on conservation and use of ecosystems and biological diversity, this approach leads to a green economic[5].

In its simplest expression, a green economy is low-carbon, resource efficient, and socially inclusive. In a green economy, growth in income and employment are driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services. http://www.unep.org/greeneconomy/Portals/88/documents/ger/ger_final_dec_2011/Green%20EconomyReport_Final_Dec2011.pdf
