- Adaptation to loss of some ecosystem services may be
possible, especially in managed ecosystems. However, adaptation
to losses in wild ecosystems and biodiversity may be difficult
or impossible.
- There is considerable capacity for adaptation in agriculture,
including crop changes and resource substitutions, but
adaptation to evolving climate change and interannual variability
is uncertain.
- Adaptations in agriculture are possible, but they will
not happen without considerable transition costs and equilibrium
(or residual) costs.
- Greater adverse impacts are expected in areas where
resource endowments are poorest and the ability of farmers
to adapt is most limited.
- In many countries where rangelands are important, lack
of infrastructure and investment in resource management
limit options for adaptation.
- Commercial forestry is adaptable, reflecting a history
of long-term management decisions under uncertainty. Adaptations
are expected in land-use management (species-selection
silviculture) and product management (processing-marketing).
- Adaptation in developed countries will fare better,
while developing countries and countries in transition,
especially in the tropics and subtropics, will fare worse. |
