Rationale

Justification for indicator selection

Suitable climate is an important factor in determining the distribution of species and the composition and stability of ecosystems. For many animal species, a major constraint on successful colonization of new areas is the absence of ecologically-linked host plants (Schweiger et al., in press). Advancements in spring activity may result in asynchrony between food sources and breeding, causing starvation of young that emerge too early, and the disruption of predator-prey relationships. This so-called trophic mismatch has been demonstrated for various animal groups, including birds (Both et al., 2006), and in some cases is causing crashes or explosions in populations. Additionally, extreme events such as floods, drought and fire can disrupt ecosystems, preventing growth of key plant species and limiting nesting, breeding and feeding opportunities for animals.

Policy context and targets

Context description

In April 2009 the European Commission presented a White Paper on the framework for adaptation policies and measures to reduce the European Union's vulnerability to the impacts of climate change. The aim is to increase the resilience to climate change of health, property and the productive functions of land, inter alia by improving the management of water resources and ecosystems. More knowledge is needed on climate impact and vulnerability but a considerable amount of information and research already exists which can be shared better through a proposed Clearing House Mechanism. The White Paper stresses the need to mainstream adaptation into existing and new EU policies. A number of Member States have already taken action and several have prepared national adaptation plans. The EU is also developing actions to enhance and finance adaptation in developing countries as part of a new post-2012 global climate agreement expected in Copenhagen (Dec. 2009).
