Abstract:
The World Bank’s mission is to alleviate poverty and support sustainable development. Climate
change is a serious environmental challenge that could undermine these goals. Since the
Industrial Revolution, the mean surface temperature of Earth has increased an average 2°
Celsius due to the accumulation of greenhouse gases in the atmosphere. Most of this change
has occurred in the past 30 to 40 years, and the rate of increase is accelerating. These rising
temperatures will have significant impacts at a global scale and at local and regional levels.
While it remains important to reduce greenhouse gas emissions and reverse climate change in
the long run, many of the impacts of climate change are already in evidence. As a result,
governments, communities, and civil society are increasingly concerned with anticipating the
future effects of climate change while searching for strategies to mitigate, and adapt to, its
current and future effects.
Global warming and changes in climate have already had observed impacts on natural
ecosystems and species. Natural systems such as wetlands, mangroves, coral reefs, cloud
forests, Arctic and high latitude ecosystems are especially vulnerable to climate‐induced
disturbances. Enhanced protection and management of biological resources and habitats can
mitigate impacts and contribute to solutions as nations and communities strive to adapt to
climate change. Biodiversity is the foundation and mainstay of agriculture, forests, and fisheries.
Biological resources provide the raw materials for livelihoods, agriculture, medicines, trade,
tourism, and industry. Forests, grasslands, freshwater, and marine and other natural ecosystems
provide a range of services, often not recognized in national economic accounts but vital to
human welfare: regulating water flows and water quality, flood control, pollination,
decontamination, carbon sequestration, soil conservation, and nutrient and hydrological cycling.
Current efforts to address climate change focus mainly on reducing emissions of greenhouse
gases, mainly through cleaner energy strategies, and on attempting to reduce vulnerability of
communities at risk by improving infrastructure to meet new energy and water needs. This
report attempts to set out a compelling argument for including ecosystem‐based approaches to
mitigation and adaptation as a third and essential pillar in national strategies to address climate
change. The report is targeted at both Bank task teams and country clients. Such ecosystem‐
based strategies can offer cost‐effective, proven and sustainable solutions contributing to, and
complementing, other national and regional adaptation strategies.
