2. “ This book clearly articulates for the first time how protected areas contribute significantly to reducing impacts of climate change and what is needed for them to achieve even more. As we enter an unprecedented scale of negotiations about climate and biodiversity it is important that these messages reach policy makers loud and clear and are translated into effective policies and funding mechanisms.”
Lord Nicholas Stern
in his preface to Natural Solutions

3. Why protected areas?
Protected areas are a proven effective governance system for managing land, coastal and marine ecosystems
Protected area systems are already established as efficient, successful and cost effective tools for ecosystem management
They have associated laws and policies, management and governance institutions, knowledge, staff and capacity

4. Why protected areas?
They contain the only remaining large natural habitats in many areas
Opportunities exist to increase their coverage of marine and coastal areas, connectivity at a landscape level and their effective management. All of which enhance the resilience of ecosystems to climate change and safeguard vital ecosystem services

5. Protected areas and climate change
Protected areas are an essential part of the global response to climate change
They can contribute to the two main responses to climate change through both:
Adaptation
and
Mitigation

6. Adaptation
The evidence for the role of using protected areas in ecosystem-based adaptation strategies

7. The challenge
Ecosystem-based adaptation is the use of biodiversity and ecosystem services as part of adaptation strategies to help us cope with the adverse effects of climate change
but
The Millennium Ecosystem Assessment estimates that 60% of global ecosystem services are degraded and so these services are rapidly being lost

8. The impacts of degraded ecosystem services
Health: spread of disease vectors, heat waves, poor sanitation due to lack of clean water
Food: shortages and crop failure
Water: shortages impacting drinking water, irrigation and hydropower potential
‘Natural disasters’: flooding, storms, drought, wildfire, pest infestations, ocean acidification

9. The opportunity Protected areas provide two key functions
Protect: maintain ecosystem integrity, buffer local climate, reduce risks and impacts from events such as storms and droughts and sea-level rise
Provide: maintain essential ecosystem services that help people cope with changes in water supplies, fisheries, disease and agricultural productivity caused by climate change

10. Protecting ecosystem integrity
Protected areas can help to reduce the impact of all but the largest natural disasters, for example
Floods: by providing space for floodwaters to disperse and through natural vegetation absorbing the impacts of flooding
Landslides: by stabilising soil and snow to stop slippage or slow movement once a slip is underway

11. Storm surges: intact natural systems such as coral reefs, barrier islands, mangroves, dunes and marshes can all help block storm surges
Drought and desertification: effective management systems can control grazing pressure and intact watersheds help to keep vital water resources in soils
Fire: natural vegetation can limit encroachment in fire-prone areas and the maintenance of traditional management systems can reduce fire risk

12. Provide natural resources
Protected areas are proven tools for maintaining essential natural resources and services, which in turn can help increase the resilience and reduce the vulnerability of livelihoods in the face of climate change
Water: forest and wetland protected areas provide both purer water and (especially in tropical montane cloud forests) increased water flow

13. Fish resources: marine and freshwater protected areas conserve and rebuild fish stocks
Food: by protecting crop wild relatives to facilitate crop breeding; through pollination services; and providing sustainable food supplies for communities
Health: habitat protection to slow the expansion of vector-borne diseases that thrive in degraded ecosystems; as well as conserving traditional medicines and providing compounds for pharmaceuticals

14. Adapting to climate change
Measures are needed to maintain the resilience of ecosystems under new climatic conditions—so that they can continue to supply essential services
Protected area management will need to be adapted, to address mitigation and adaptation needs, in addition to biodiversity management objectives.

15. How protected areas can deliver even more
Understanding: assess and manage protected area services and benefits
Adaptive management: consider climate impacts and climate solutions in protected area planning and management
Integrate: include protected areas into national and local adaptation strategies

16. Resilience: improve ecosystem resilience particularly when ecosystem services are under threat
Restoration and connectivity: maintain and enhance ecosystem integrity
Economics: realise the theoretical – goods and services from an effectively managed and representative protected area system could have a value of between US$4,400 and $5,200 billion a year. But protected area systems are currently under-resourced and under-funded

17. The challenge for protected areas
Integrity: ensure that protected areas are capable of delivering potential services by ensuring:
Effective management of current areas
More protection, particularly in under-represented areas such as freshwater and marine areas
Use of all governance and management types

18. Trade-offs: guidance on how we manage climate impacts on biodiversity and ecosystem-based adaptation strategies
Resilience: research and management advice to understand how we build resilience of protected areas
Partnerships: with relevant sectors and communities – disaster relief agencies, seed companies, water companies, fishers, farmers etc
Policy: enabling environment linking biodiversity and climate change policy

19. The potential to use protected areas in carbon storage and capture
Mitigation
The potential to use protected areas in carbon storage and capture

20. The challenge
Land use conversion is already responsible for around 20% of global greenhouse gas emissions
…and furthermore…
According to the IPCC many ecosystems that are currently sinks for CO2 could become sources of emissions, with a temperature increase of just 2.5OC

21. The opportunity Natural ecosystems offer two key functions
Storing existing carbon in vegetation and soils and thus preventing further loss
Capturing additional carbon dioxide from the atmosphere and thus reducing net greenhouse gas levels

22. Carbon storage
Natural ecosystems currently sequester about half of the current GHG emissions. Major carbon stores exist in soil, forest, peat and inland waters, grassland, mangroves, coastal marshes and sea grass
Estimates for the amount of carbon stored in tropical forests range from t/ha. Temperate and boreal forests are also major sinks. The highest known carbon storage is in a Eucalyptus forest.

23. Carbon storage
Peat probably stores more – an estimated 550 Gt is stored globally. But emissions from degraded peat were estimated at 1,298 Mt, plus over 400 Mt from peat fires, threatening this store
Mangroves, sea grass beds and salt marshes all store substantial amounts of carbon although these sources have been largely ignored

24. Carbon storage
Grasslands may hold more than 10% of total carbon, but mismanagement and conversion is causing major losses – grassland are one of the most un-protected biomes
Estimates of soil carbon vary but it is thought to be the largest terrestrial store. Agriculture is often a source rather than sink but changes in farming (less tillage, more organic methods etc) can help build carbon stocks

25. Carbon capture
Most ecosystems can also continue to capture carbon dioxide from the atmosphere

26. Carbon capture
Both young and old forests capture significant amounts of carbon dioxide, as do peatlands, grasslands and many marine ecosystems
Research in the Amazon, Congo Basin and in boreal forests show that old-growth forests continue to sequester carbon
Sequestration from commercial forests depends largely on whether use is short- term (e.g. newspapers) or long-term

27. How protected areas can deliver
Protected areas are the most effective tool yet found for maintaining carbon in natural vegetation
The UNEP World Conservation Monitoring Centre estimates that at least 15% of terrestrial carbon is stored in protected areas

28. The challenge for protected areas
New skills, tools and funding opportunities will be needed to make best use of available management options
Gap analysis for protected area design may need to start including carbon
New staff skills will be required
Protected areas need to be included in REDD and similar funding schemes

29. Policy responses
Opportunities to use protected areas in climate response strategies need to be prioritised in three key areas

30. Policy requirements
United Nations Framework Convention on Climate Change (UNFCCC): needs to recognise protected areas as tools for mitigation and adaptation to climate change; and open up key climate change related funding mechanisms, including REDD (Reducing Emissions from Deforestation and Degradation) and adaptation funds, to the creation, enhancement and effective management of protected area systems

31. Policy requirements
Convention on Biological Diversity (CBD): needs to renew the Programme of Work on Protected Areas at the 10th Conference of the Parties (COP10) in 2010 to address more specifically the role of protected areas in responses to climate change, in liaison with other CBD programmes

32. Policy requirements
National and local governments: although ecosystem-based solutions are not a panacea and should not replace attempts to reduce emissions from fossil fuel combustion, protected area systems should be incorporated into national climate change strategies and action plans, as tools for mitigation by reducing the loss and degradation of natural habitats, and adaptation by reducing the vulnerability and increasing reliance
