ecological resilience wiki

RESILIENCE AND STABILITY OF ECOLOGICAL SYSTEMS 5 predator populations, and growth of the predator population is linearly proportional to the same product. Regime shifts are driven by the interaction of fire, herbivory, and variable rainfall. However, as a result of agricultural intensification and the application of herbicides to control weeds, fertilisers to accelerate and increase crop growth and pesticides to control insects, plant biodiversity is reduced as is the supply of organic matter to replenish soil nutrients and prevent run-off. Resilience is the ability to bounce back from tough situations and to avoid becoming a victim of helplessness. [25] Ross draws on the impact of climate change on the global agenda as a fundamental factor in the "shift towards ecological sustainability" as an alternative approach to that of sustainable development. Individualist cultures, such as those of the U.S., Austria, Spain, and Canada, emphasize personal goals, initiatives, and achievements. This is a subset of a notion of environmental resilience.. Overview. In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. [1][2], Mulga woodlands of Australia can exist in a grass-rich regime that supports sheep herding, or a shrub-dominated regime of no value for sheep grazing. [14] [18] [19] A similar conclusion is drawn by Perman et al. If the disturbance is of sufficient magnitude or duration, a threshold may be reached where the ecosystem undergoes a regime shift, possibly permanently. One of the main results of climate change is rising sea water temperature which has a serious effect on coral reefs, through thermal-stress related coral bleaching. Sub-domains of sustainable development have been considered also: cultural, technological and political. Scientific research associated with resilience is beginning to play a role in influencing policy-making and subsequent environmental decision making. Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state. Content on this site is subject to our reposting policy . Any impact that development has upon threatened ecosystems must consider the health and resilience of these ecosystems. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil, and the introduction of exotic plant or animal species. 8, United Nations Environment Programme. We have created a browser extension. Resilience questions the free market model within which global markets operate. The change of regimes, or the shift, usually occurs when a smooth change in an internal process (feedback) or a single disturbance triggers a completely different system behavior. Either state can be resilient dependent upon management.[1][2]. However, due to a lack of a clear definition and the diversity involved with the environment, the implementation has been lagging. The organic matter (elements carbon and nitrogen) in soil, which is supposed to be recharged by multiple plants, is the main source of nutrients for crop growth. Ecological and social resilience may be linked through the Environmental resource management is the management of the interaction and impact of human societies on the environment. Panarchy: the degree to which a certain hierarchical level of an ecosystem is influenced by other levels. [24] Becoming more apparent in academic writing is the significance of the environment and resilience in sustainable development. Ecological Concept: Resilience and Resistance. Boundary objects have benefits of bringing people together from different disciplines, as long as there is awareness of the potential for misunderstanding. (online first). [3] Human activities that adversely affect ecological resilience such as reduction of biodiversity, exploitation of natural resources, pollution, land use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Ecosystem services are the many and varied benefits to humans provided by the natural environment and from healthy ecosystems. The workbook wiki is based on Version 1.0 of the Practitioner's workbook "Assessing and Managing Resilience in Social-Ecological Systems". Submission to TfC e-Journal. The concept of resilience in ecological systems was first introduced by the Canadian ecologist C.S. The first three can apply both to a whole system or the sub-systems that make it up. Hart. [20] Resilience science has been evolving over the past decade, expanding beyond ecology to reflect systems of thinking in fields such as economics and political science. [9] The larger the scale of damage, the more difficult it is for the forest ecosystem to restore and maintain its balance.
