The growing appreciation of water's value to maintaining healthy ecosystems and their services also calls for an integrated approach.

Air pollution also adversely affects natural ecosystems, for instance, through damage to plant growth, acidification of waterways, accumulation of mercury in the food chain and eutrophication of coastal ecosystems, all leading to impacts on agriculture, fisheries, forests and a host of ecosystems services upon which all life depends.

Yet ecosystems and their goods and services are being degraded under the pressure of social and economic driving forces at national, regional and global levels.

Measurement of a persistent reduction in the capacity of ecosystems to supply services provides a robust and operational way of quantifying land degradation, and thus desertification.

Destruction of ecosystems

(a) Protecting vulnerable marine ecosystems

The pressure is increasing on dryland ecosystems for the provision of services such as food, forage, fuel, building materials, and water for humans and livestock, for irrigation, and for sanitation.

Tailored to the degree of aridity, interventions and adaptations are available and used to prevent desertification and to restore, where needed, the capacity of the dryland ecosystems to provide services.

The loss of services derived from ecosystems is a significant barrier to the achievement of the Millennium Development Goals to reduce poverty, hunger, and disease. (Living Beyond Our Means, p. 2)

(a) Protection and preservation of ecosystems

Underlines also the importance of enhancing the sustainability of ecosystems that provide essential resources and services for human well being and economic activity and developing innovative means of financing for their protection

15. Underlines also the importance of enhancing the sustainability of ecosystems that provide essential resources and services for human well being and economic activity and developing innovative means of financing for their protection

However, urgent action was required to maintain the environmental foundation of sustainable livelihoods, since ecosystems were still being eroded and the essential services derived therefrom were still being used in an unsustainable manner.

avoid lasting environmental damage and protect ecosystems

(g) Naturally occurring meso scale marine ecosystems

Coral reef ecosystems are invaluable human treasures.

We fundamentally depend on natural ecosystems and resources provided by watersheds and aquifers, coastal and marine ecosystems, mountains, forests, soils and the atmosphere.

Such an approach takes account of the priority concerns for improving the living conditions of the populations whose subsistence depends directly on the products and services provided by the ecosystems in which they live.

If they disappear, whole ecosystems in Africa disappear.

If you look inside the restrooms, they all have really similar ecosystems, and if you were to look inside the classrooms, those also have similar ecosystems.

We see entire ecosystems where gas is being recycled.

There is some modeling of ecosystems going on now.

How has desertification affected ecosystems and human well being?

The microbes in your mouth can freshen your breath, or not, and the key thing is that our personal ecosystems interact with ecosystems on everything we touch.

(e) The assessment of 66 subregions covering international river basins and adjacent seas conducted by GIWA has confirmed the widespread concern that pressures from human activities have weakened the ability of aquatic ecosystems to provide critical services.

Fifteen of the 24 essential services provided by the ecosystems we have at our disposal ranging from food production to water quality and availability, disease management and climate regulation are being used unsustainably and are persistently eroded.

Many other ecosystems on Earth are in real, real danger.

(d) To ensure conservation and, where necessary, restoration of ecosystems.

Collaboration between the Chemosynthetic Ecosystems Group and the Seamounts Group

Studies such as the The Millennium Ecosystem Assessment and The Economics of Ecosystems and Biodiversity (TEEB), conducted on behalf of the G 8, have improved our understanding of the economic, ecological, and social value of the goods and services provided by ecosystems, and have proposed better methods for pricing them. Yet this new thinking has yet to influence significantly the behavior of bond investors and rating agencies.

They're not going to clog up Earth's ecosystems. They work great.

Marine environment, marine resources and the protection of vulnerable marine ecosystems

Parties also used biophysical and process based models to simulate impacts on agriculture, water resources, coastal zones and marine ecosystems, forests and terrestrial ecosystems, human health, fisheries, settlements, energy and tourism.

Coastal zones and marine ecosystems Vulnerability assessments of coastal zones and marine ecosystems were based on both qualitative and quantitative analyses of the impacts of climate change and sea level rise.

These ecosystems are really important to the Montana brewers and their customers.

We've returned more than four billion gallons of water to degraded ecosystems.

California s enclave of tech companies remains the crown jewel of entrepreneurial ecosystems.

Forest conservation and protection of unique types of forests and fragile ecosystems

Poverty could be reduced only if ecosystems were conserved and properly managed.

Desertification can also be avoided by reducing the stress on dryland ecosystems.

Options include improved ecosystem management, rehabilitation of degraded ecosystems and wetlands protection.

(g) Improving the protection and management of terrestrial, coastal and marine ecosystems

Increasing water use and redistribution of freshwater flows, human induced land and ecosystems changes, pollution, over fishing, invasive species combined with natural processes have resulted in dramatic and sometimes extraordinary changes in lake ecosystems.

The Asian Cities Climate Change Resilience Network is restoring vital ecosystems like forest mangroves.
