The Economics of Ecosystems and Biodiversity (TEEB)

in

Why is it still the economic that is still considered to be 'real' value?
The Economics of Ecosystems and Biodiversity (TEEB) study is a major international initiative to draw attention to the global economic benefits of biodiversity, to highlight the growing costs of biodiversity loss and ecosystem degradation, and to draw together expertise from the fields of science, economics and policy to enable practical actions moving forward.

Banking On Nature’s Assets

And another

Humanity depends on nature for physical and spiritual sustenance, livelihoods, and survival. Ecosystems provide numerous benefits or "ecosystem services" that underpin economic development and support human well-being. The UN-led Millennium Ecosystem Assessment audited the health of 24 ecosystem services globally and reported that two-thirds had been degraded over the past half century. This degradation is undermining development progress. However, by accounting for and managing ecosystem service trade-offs, multilateral development banks (MDBs) and partner countries can improve development outcomes, help address climate change, and reduce costs to people and economies. Toward this end, a growing number of tools are emerging to help factor ecosystem services into economic development decisions. This report identifies entry points for mainstreaming ecosystem services in MDBs' core operations and describes a portfolio of tools to help. It also presents a range of policy options that MDBs can help country partners to implement in order to sustain critical ecosystem services.
