Adaptive capacity relates to the capacity of
systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or to respond to consequences.[1] In the context of
ecosystems, adaptive capacity is determined by
genetic diversity of
species,
biodiversity of particular ecosystems in specific
landscapes or
biome regions. In the context of coupled socio-ecological social systems, adaptive capacity is commonly associated with the following characteristics: Firstly, the ability of
institutions and
networks to
learn, and store
knowledge and experience. Secondly, the
creative flexibility in
decision making,
transitioning and
problem solving. And thirdly, the existence of
power structures that are responsive and consider the
needs of all
stakeholders.
In the context of
climate change adaptation, adaptive capacity depends on the inter-relationship of social, political, economic, technological and institutional factors operating at a variety of scales.[2] Some of these are generic, and others are exposure-specific.
Building adaptive capacity is particular important in the context of climate change, where it refers to a latent capacity - in terms of resources and assets - from which adaptations can be made as required depending on future circumstances. Since future climate is likely to be different from the present climate, developing adaptive capacity is a prerequisite for the
adaptation that can reduce the potential negative effects of exposure to climate change. In climate change, adaptive capacity, along with hazard, exposure and vulnerability, is a key component that contributes to risk, or the potential for harm or impact.[4]
Characteristics
Adaptive capacity can be enhanced in a number of different ways. A report by the
Overseas Development Institute introduces the local adaptive capacity framework (LAC), featuring five core characteristics of adaptive capacity.[5] These include:
Asset base: the availability of a diverse range of key livelihood assets that allow households or communities to respond to evolving circumstances
Institutions and entitlements: the existence of an appropriate and evolving institutional environment that allows for access and entitlement to key assets and capitals
Knowledge and information: the ability households and communities have to generate, receive, assess and disseminate knowledge and information in support of appropriate adaptation options
Innovation: the system creates an enabling environment to foster innovation, experimentation and the ability to explore niche solutions in order to take advantage of new opportunities
Flexible forward-looking decision-making and governance: the system is able to anticipate, incorporate and respond to changes with regards to its governance structures and future planning.[6]
Many development interventions - such as
social protection programmes and efforts to promote
social safety nets - can play important roles in promoting aspects of adaptive capacity.
Relationship between adaptive capacity, states and strategies
Adaptive capacity is associated with
r and K selection strategies in ecology and with a movement from explosive
positive feedback to sustainable negative feedback loops in social systems and technologies.[7][8]
The Resilience Alliance shows how the
logistic curve of the r phase positive feedback, becoming replaced by the K negative feedback strategy is an important part of adaptive capacity.[9] The r strategy is associated with situations of low complexity, high resilience, and growing potential. K strategies are associated with situations of high complexity, high potential and high resilience, but if the perturbations exceed certain limits, adaptive capacity may be exceeded and the system collapses into another so-called Omega state, of low potential, low complexity and low resilience.[10]
Adaptive capacity in the context of climate change covers human, natural, or managed systems. It looks at how they respond to both climate
variability and extremes. It covers the ability of a system to adjust to climate change to moderate potential damages, to take advantage of opportunities, or to cope with consequences.[11] Adaptive capacity is not the same as adaptation itself.[12] Adaptive capacity is the ability to reduce the likelihood of negative impacts of climate-related hazards.[13] It does this through the ability to design and implement effective adaptation strategies, or to react to evolving hazards and stresses. Societies that can respond to change quickly and successfully have a high adaptive capacity.[14] Conversely, high adaptive capacity does not necessarily lead to successful adaptation action. It does not necessarily succeed in goals of equity and enhancing well-being.[15]: 164 For example, adaptive capacity in Western Europe is generally considered to be high. Experts have documented the risks of warmer winters increasing the range of livestock diseases. But many parts of Europe were still badly affected by outbreaks of
bluetongue virus in livestock in 2007.[16]
