The capacity of ecosystems to provide serv … The capacity of ecosystems to provide services is determined
by many different direct and indirect driving forces
operating at the local to global level. (See Chapters 1 and
7.) Changes in driving forces will catalyze changes in the
provision of ecosystem goods and services. In this chapter,
we estimate the future changes in ecosystem services according
to changes in driving forces described in the MA
scenarios. The expectations about the future of ecosystem
services are consistent with the storylines presented in
Chapters 5 and 8.
We present estimates of changing ecosystem services in
the form of both qualitative and quantitative information.
The qualitative information is based on our interpretation
of the storylines presented in Chapters 5 and 8, while the
quantitative information is based on a modeling analysis,
also related to the storylines, as explained below. ted to the storylines, as explained below.
