9. Ecosystem-based approaches for adaptation and impacts of adaptation activities on biodiversity

Authors: Robert Munroe (BirdLife) and Nicky Jenner (FFI)


UNFCCC definition of adaptation is the ‘adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities’1. Various types of adaptation can be distinguished, including anticipatory and reactive adaptation, and autonomous and planned adaptation2. Planned human adaptation to climate change may be achieved in many different ways. One approach has been termed Ecosystem-based approaches for Adaptation (EbA). This approach includes sustainable management, conservation and restoration of ecosystems as part of an overall adaptation strategy that takes into account the multiple social, economic and cultural co-benefits for local communities.

Ecosystems are an important consideration in the adaptation process. On the one hand, sustainable management of ecosystems can itself contribute to adaptation and is particularly applicable in supporting adaptation among vulnerable communities3 that are highly dependent on natural resources for their livelihoods. This can be achieved through:

  • Increasing resilience to climate change to help support continued ecosystem service provision (see Chapter 8), including the maintenance of supporting services (e.g. nutrient cycles), through to provisioning services.
  • Strategic use of ecosystem goods and services that provide direct adaptation benefits to local communities, such as wetlands’ flood regulation and mangrove’s storm surge mitigation services.

On the other hand, societal adaptation measures4 can negatively impact ecosystems and undermine the services they provide. For example, flood barriers constraining natural periodic cycles such as annual river flooding, and the impact of hard infrastructural alternatives, such as sea-walls rather than maintaining coastal mangroves, may have significant impacts on biodiversity. However, there may be situations where these solutions may be ignored due to short-term needs or immediate crisis or because of the tipping point (see Chapter 7) at which an ecosystem stops providing the services neccessary for adaptation has been, or is soon to be reached.

Examples of ecosystem-based approaches for adaptation activities include:

  • Coastal defence through the maintenance and/or restoration of mangroves and other coastal wetlands to reduce coastal flooding and coastal erosion. These ecosystems have high productivity enabling them to add considerable volume to trapped sediments around their roots, causing soils to grow upwards reducing the rate of SLR compared to unvegetated sites and certainly reducing wave height.
  • Adapting the design and management of marine protected areas to protect coral reefs and shellfish reefs and their ability to act as natural breakwaters and dissipate wave energy and sustain fish habitat.
  • Sustainable management of upland wetlands and floodplains for maintenance of water flow and quality.
  • Making space for nature – removal of hard man-made river banks and blueways through urban areas, greenways through urban areas, sustainable urban drainage systems.
  • Conservation and restoration of forests to stabilize land slopes and regulate water flows, preventing flash flooding and landslides as rainfall levels and intensity increase.
  • Establishment of diverse agroforestry systems providing flexible livelihood options to cope with increased risk from changed climatic conditions and have potential to support greater biodiversity.
  • Conservation of agro-biodiversity to provide specific gene pools for crop (e.g. drought resistant whilst less reliant on chemical inputs) and livestock (e.g. water efficient) adaptation to climate change, and to maintain soil moisture and nutrients.

If designed, implemented and monitored appropriately, with full involvement of indigenous peoples and local communities that follows the highly complementary community-based adaptation (CbA) approach (see box 1), ecosystem-based approaches for adaptation can be a useful and widely applicable approach to adaptation because they:

  • Can be applied at regional, national and local levels, at both project and programmatic levels, and benefits can be realized over short and long time scales.
  • May be more cost-effective and more accessible and enduring than measures based on hard infrastructure and engineering (although in some cases these will certainly be necessary) to rural or poor communities because they provide local benefits and can be locally managed and maintained.
  • Can integrate and maintain traditional and local knowledge and cultural values.
  • Generate multiple social, economic and cultural co-benefits for local communities, including contributing to climate change mitigation by conserving carbon stocks, reducing emissions caused by ecosystem degradation and loss and enhancing carbon stocks.
  • Contribute to the conservation and sustainable use of biodiversity.
  • Through participatory approaches, it presents a tangible opportunity to align conservation; development; poverty alleviation; disaster risk reduction; humanitarian aid; water, agricultural, forestry, tourism, health sector, interests and build integrated approaches to adaptation (that avoid mal-adaptation5).
Box 1: 
Community-based adaptation. Community-based adaptation is one of the fastest-developing approaches to adaptation. Complementing a top-down approach, e.g. UNFCCC helping a nation develop a National Adaptation Plan of Action, which they then pass down to lower levels of government for implementation, it draws on participatory approaches and methods developed in both disaster risk reduction and community development work. It is based on the premise of understanding how climate change will affect the local environment and a community’s assets and capacities, including knowledge and practices of coping with past and present climate-related hazards, and prioritising adaptation practices accordingly. Ecosystem-based approaches for adaptation and community-based adaptation (CbA) are often closely linked and should be mutually reinforcing. Many examples of ecosystem-based approaches are locally managed and appropriate, and are informed by local and traditional knowledge. CbA is often intimately connected with the health of and services provided by ecosystems. Together they help underpin good adaptation policy, planning and delivery, and are especially significant to communities and peoples directly dependent on natural resources for their livelihoods. 
 

Ecosystem-based approaches for adaptation may require managing ecosystems to provide particular services at the expense of others. For example, using wetlands for coastal protection may require emphasis on silt accumulation and stabilization possibly at the expense of wildlife values and recreation. It is therefore important that decisions to implement ecosystem-based approaches for adaptation are subject to full and effective participation, risk assessment, scenario planning, and adaptive management approaches that recognise and incorporate potential trade-offs over time and space but also between different ecosystem goods and services.

In most cases there is the potential to increase positive and reduce negative impacts of adaptation on biodiversity. To help achieve this, the practical implementation of adaptation and adaptation policy options should consider:

  • Use of environmental mainstreaming tools such as strategic environmental assessments (SEAs) and environmental impact assessments (EIAs – for individual sites) in planning and policy, and in project and programme delivery, and ensure that these tools incorporate adaptation considerations and an ecosystem approach6.
  • Ensure full and effective participation by following the CbA tools in the Key Tools section below.
  • Collect, conserve and disseminate traditional and local knowledge, innovations and practices related to coping mechanisms and adaptation where appropriate and with free, prior and informed consent from traditional knowledge holders to help ensure effective and locally appropriate adaptation.
  • Establishing monitoring processes to detect any positive or negative impacts of adaptation on biodiversity and people, and point samples on climate data to inform a ‘learning by doing’ approach. Consider participatory monitoring approaches that are designed and managed by those most likely to be involved in and/or affected by adaptation strategies.
  • Maintain intact and interconnected ecosystems to increase resilience and allow biodiversity and people to adjust to changing environmental conditions.
  • Integrate the role of ecosystems in human adaptation into national adaptation plans, and then link or integrate these with other strategic plans and processes such as those related to: development, poverty reduction, land-use, biodiversity, business sectors (agriculture, water, transport, energy, tourism).
  • These considerations should be integrated into national and international adaptation finance safeguards.

The Cancun Adaptation Framework, the decision on adaptation to come out of UNFCCC COP16, Cancun, Dec 2010, that guides international and national action, makes clear that:

  • As part of the principles guiding adaptation, adaptation action should consider vulnerable ecosystems and be integrated into relevant social, economic and environmental policies and actions
  • Parties are invited to undertake adaptation in the areas of terrestrial, freshwater and marine ecosystems and coastal zones
  • To undertake environmental evaluations of adaptation options
  • To build resilience of ecological systems, include through sustainable management of natural resources
  • Adaptation actions, plans and programmes are to be implemented in and across different economic and social sectors and ecosystems.

 

Key Questions:

  1. What is the effect of biodiversity loss on developing country communities’ ability to adapt?
  2. What are the potential trade-offs of ecosystem-based approaches to adaptation?
  3. Are ecosystem-based approaches for adaptation more cost-effective than ‘hard’ infrastructure – how to measure the costs and benefits in order to ensure accounting of ecosystems in assessments of economics of adaptation?
  4. How to ensure that the role of ecosystems in human adaptation is considered in all adaptation activities?
  5. How to overcome association of ecosystem-based approaches being conservation ‘business-as-usual’?

3Vulnerability = exposure to climate change impacts + sensitivity to those impacts (e.g. dependence on environment, high inequalities) + adaptive capacity (e.g. ability to adapt)

4Societal adaptation can involve societal changes, such as proactive capacity building or migration; socio-economic changes such as insurances, sustainable development and resource management; and technical fixes, such as efficient cooling systems, desalinisation, and flood barriers.

5Adaptation that leads to perverse outcomes, for example, poor synergies between adaptation plans/projects that lead to increasing vulnerability of ‘downstream’ community, and destroying biodiversity and important ecosystem services.

6A strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. It involves taking account of vital ecosystem functions and valuing the ecological goods and services they provide in all decision-making processes. ‘The Ecosystem Approach’ is the primary framework for action under the CBD.
