Biodiversity is crucial to the reduction of poverty, due to the basic goods and ecosystem services it provides. Globally, some 2.6 billion people worldwide draw their livelihoods either partially or fully from agriculture. More than 3 billion people depend on marine and coastal biodiversity, while over 1.6 billion rely on forests and non-timber forest products. Loss of biodiversity poses a significant threat to their livelihoods. Biodiversity must therefore be protected and sustainably used for achieving poverty reduction and sustainable development.
In order to link biodiversity considerations with poverty eradication and sustainable development, the environmental community and the stakeholders who specifically deal with the economic and social dimensions of development need a common framework, a common language. The concept of “ecosystem services” provides such a language as it describes “the benefits people obtain from ecosystems."
Ecosystem services include provisioning services such as food and water; regulating services such as flood and disease control; cultural services such as spiritual, recreational, and cultural benefits; and supporting services such as nutrient cycling that maintain the conditions for life on Earth.
