ecological resilience wiki

Ecosystems may transition from one stable state to another, in what is known as a state shift, when perturbed. Capacity of ecosystems to resist and recover from change, Vandana Shiva | Ecofeminism and the decolonization of women, nature and the future. Scientific research associated with resilience is beginning to play a role in influencing policy-making and subsequent environmental decision making. Sustainable use of environmental goods and services requires understanding and consideration of the resilience of the ecosystem and its limits. The concept of ecological resilience presumes the existence of multiple stability domains and the tolerance of the system to perturbations that facilitate transitions among stable states. To be able to manage fisheries efficiently and effectively it has become increasingly more pertinent to understand not only the biological aspects of the species being studied, but also the environmental variables they are experiencing. “Linking Social and Ecological Systems: Management practices and social mechanisms for building resilience”. 26. [1] [2]. CS1 maint: multiple names: authors list (, YPTE 2010 Overfishing: Environmental Facts. Holling [6] in order to describe the persistence of natural systems in the face of changes in ecosystem variables due to natural or anthropogenic causes. Ecological resilience is the ability of an ecosystem to respond to some kind of disturbance - a measure of how quickly they recover. Would you like Wikipedia to always look as professional and up-to-date? [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.[25]. It is thus linked to environmental protection, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, and wildlife management, and others. [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. [22], More recently, it has been suggested by Andrea Ross that the concept of sustainable development is no longer adequate in assisting policy development fit for today's global challenges and objectives. This is governed by the, International level initiatives aim at improving socio-ecological resilience worldwide through the cooperation and contributions of scientific and other experts. People in this culture tend to describe themselves in terms of their unique traits- “I am analytical and curious” (Ma et a… Also, the mining of cobalt in Africa or lithium in Argentina – key ingredients if lithium ion batteries – is implicated in slavery {13} and the abuse of indigenous people’s rights {14} . Ecological Concept: Resilience and Resistance. The workbook wiki is aimed at those who have experience applying resilience concepts to social-ecological systems and who want to contribute to the on-going … The ability of ecosystems to recover from certain levels of environmental impact is not explicitly noted in legislation, however, because of ecosystem resilience, some levels of environmental impact associated with development are made permissible by environmental policy-making and ensuing legislation. Inherent to the successful operation of a free market is specialisation which is required to achieve efficiency and increase productivity. An example of such an initiative is the. [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. [22], More recently, it has been suggested by Andrea Ross that the concept of sustainable development is no longer adequate in assisting policy development fit for today's global challenges and objectives. Sustainability is the ability to exist constantly. [7] Adaptive capacity in socio-ecological systems refers to the ability of humans to deal with change in their environment by observation, learning and altering their interactions.[2]. Whereas previous literature has focused on the role of traditional ecological knowledge as a social mechanism that fosters adaptation in the face of disturbance and related processes fundamental to social–ecological system resilience (Berkes and Turner 2006), Tidball et al. These systems contrast with freshwater ecosystems, which have a lower salt content. This is a subset of a notion of environmental resilience.. Overview. I use WIKI 2 every day and almost forgot how the original Wikipedia looks like. In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. In addition to overfishing, coastal communities are suffering the impacts of growing numbers of large commercial fishing vessels in causing reductions of small local fishing fleets. [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. [1] As the concept of sustainable development has evolved beyond the 3 pillars of sustainable development to place greater political emphasis on economic development. Berkes, F. and Folke, C., (ed Colding, J.) Lee, M. (2005) “EU Environmental Law: Challenges, Change and Decisions Making”. [13] Blue fin tuna is at particular risk of extinction. In ecology, the theory of alternative stable states predicts that ecosystems can exist under multiple "states". (2007). In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Observed resilience within specific ecosystems drives management practice. This is because the concept of sustainable development is "based on weak sustainability" which doesn't take account of the reality of "limits to earth's resilience". The first three can apply both to a whole system or the sub-systems that make it up. 26, 52, 86. Ecosystem-based management is an environmental management approach that recognizes the full array of interactions within an ecosystem, including humans, rather than considering single issues, species, or ecosystem services in isolation. According to the International Maritime Organisation oil spills can have serious effects on marine life. Environmental resource management is the management of the interaction and impact of human societies on the environment. [5]. Individualist cultures, such as those of the U.S., Austria, Spain, and Canada, emphasize personal goals, initiatives, and achievements. [2] When such thresholds are associated with a critical or bifurcation point, these regime shifts may also be referred to as critical transitions. The discharges of nitrogen, phosphorus, and other nutrients come from agriculture, waste disposal, coastal development, and fossil fuel use. Ecological resilience provides a theoretical foundation for understanding how complex systems adapt to and recover from localized disturbances like hurricanes, fires, pest outbreaks, and floods, as well as large-scale perturbations such as climate change. These include agriculture, deforestation, pollution, mining, recreation, overfishing, dumping of waste into the sea and climate change. Some ecosystems can shift greatly from their previous state and still return to pre-disturbance conditions. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. An example of such an initiative is the. The term deforestation has a meaning that covers crossing the threshold of forest's resilience and losing its ability to return its originally stable state. Walker, J. (online first). “Natural Resource and Environmental Economics”. The first three can apply both to a whole system or the sub-systems that make it up. “Why we Disagree about Climate Change: Understanding Controversy, Inaction and Opportunity". 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. Spills are not the only pressure on marine habitats; chronic urban and industrial contamination or the exploitation of the resources they provide are also serious threats. Between 1997-1998 the most significant worldwide coral bleaching event was recorded which corresponded with the El Nino Southern Oscillation, with significant damage to the coral reefs of the Western Indian Ocean.[11]. Although such non-linear changes have been widely studied in different disciplines ranging from atoms to climate dynamics, regime shifts have gained importance in ecology because they can substantially affect the flow of ecosystem services that societies rely upon, such as provision of food, clean water or climate regulation. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities suc Deforestation also decreases biodiversity of both plant and animal life and can lead to an alteration of the climatic conditions of an entire area. The group wanted to define a "safe operating space for humanity" for the international community, including governments at all levels, international organizations, civil society, the scientific community and the private sector, as a precondition for sustainable development. Popisuje míru, do které je systém schopný sebeorganizace, učení a přizpůsobení. Planetary boundaries is a concept involving Earth system processes that contain environmental boundaries. Ecological collapse can be considered as a consequence of ecosystem collapse on the biotic elements that depended on the original ecosystem. Marine ecosystems are the largest of Earth's aquatic ecosystems and are distinguished by waters that have a high salt content. However, the elements which influence ecosystem resilience are complicated. This is governed by the, International level initiatives aim at improving socio-ecological resilience worldwide through the cooperation and contributions of scientific and other experts. [24] Becoming more apparent in academic writing is the significance of the environment and resilience in sustainable development. Ecological resilience and the thresholds by which resilience is defined are closely interrelated in the way that they influence environmental policy-making, legislation and subsequently environmental management. [23], The purpose of ecological resilience that is proposed is ultimately about averting our extinction as Walker cites Holling in his paper: "[..] "resilience is concerned with [measuring] the probabilities of extinction” (1973, p. 20)". This very act of specialisation weakens resilience by permitting systems to become accustomed to and dependent upon their prevailing conditions. Resilience refers to ecosystem's stability and capability of tolerating disturbance and restoring itself. Ecosystem resilience impacts upon the way that development is permitted/environmental decision making is undertaken, similar to the way that existing ecosystem health impacts upon what development is permitted. “Linking Social and Ecological Systems: Management practices and social mechanisms for building resilience”. “The Strange Evolution of Holling’s Resilience or The Resilience of Economics and the Eternal Return of Infinite Growth”. Ecological and social resilience may be linked through the propose that safeguarding the environment to "deliver a set of services" should be a "necessary condition for an economy to be sustainable". For example, organisms living in communities that are in isolation from one another may be organized differently from the same type of organism living in a large continuous population, thus the community-level structure is influenced by population-level interactions. When resilience is observed to be low, or impact seems to be reaching the threshold, management response can be to alter human behavior to result in less adverse impact to the ecosystem. In the marine realm, they are highly challenging to quantify due to highly migratory species as well as rapidly changing environmental and anthropogenic factors that can alter the habitat rather quickly. Due to ecological feedbacks, ecosystems display resistance to state shifts and therefore tend to remain in one state unless perturbations are large enough. Zooplankton eat the toxic algae and begin passing the toxins up the food chain, affecting edibles like clams, and ultimately working their way up to seabirds, marine mammals, and humans. [25]. These ecosystems, functioning in healthy relationship, offer such things like natural pollination of crops, clean air, extreme weather mitigation, human mental and physical well-being. Common examples include increases in asthma rates due to air pollution, PCB contamination of game fish in the Great Lakes of the United States, and habitat fragmentation leading to increasing rates of Lyme disease. Cambridge University Press. (2003). This very act of specialisation weakens resilience by permitting systems to become accustomed to and dependent upon their prevailing conditions. Resilience has been defined in two ways in ecological literature: The second definition has been termed ‘ecological resilience’, and it presumes the existence of multiple stable states or regimes. (1998). Read Wikipedia:Contributing FAQ and leave any messages at the project talk page. [7], Some shallow temperate lakes can exist within either clear water regime, which provides many ecosystem services, or a turbid water regime, which provides reduced ecosystem services and can produce toxic algae blooms. Resilience has been defined in two ways in ecological literature: as the time required for an ecosystem to return to an equilibrium or steady-state following a perturbation; this definition of resilience is used in other fields such as physics and engineering, hence has been termed ‘engineering resilience’ by Holling. “ the Strange Evolution of Holling’s resilience or the sub-systems that make up.
