Glossary definitions

A dynamic complex of plant, animal and micro-organism communities and their non- living environment interacting as a functional unit.

A dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit.

The conservation, sustainable management and restoration of natural ecosystems to help people adapt to climate change.

The use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change (CBD, 2012). It refers to actions that mix the use of biodiversity and ecosystem services policy instruments with socio-economic and development policy instruments to help people adapt to the adverse effects of climate change.

A strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. An ecosystem approach is based on the application of appropriate scientific methods, focused on levels of biological organization that encompass the essential structure, processes, functions and interactions among and between organisms and their environment. It recognizes that humans, with their cultural diversity, are an integral component of many ecosystems.

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

A transition area between two biomes or vegetation types.

Sustainable travel undertaken to access sites or regions of unique natural or ecological quality, promoting their conservation, low visitor impact, and socio-economic involvement of local populations.

Sustainable travel undertaken to access sites or regions of unique natural or ecological quality, promoting their conservation, low visitor impact, and socio- economic involvement of local populations.

Often referred to as cold-blooded and applied to organisms that cannot regulate their body temperature relative to the surrounding environment, i.e. deriving heat from outside the body.

A change in species composition, physical conditions or ecological factors at the boundary between two or more habitats.

An irregularly recurring flow of unusually warm surface waters from the Pacific Ocean toward and along the western coast of South America that prevents upwelling of nutrient- rich cold deep water and that disrupts typical regional and global weather patterns.

The term El Niño was initially used to describe a warm-water current that periodically flows along the coast of Ecuador and Perú, disrupting the local fishery. It has since become identified with a basin-wide warming of the tropical Pacific Ocean east of the dateline. This oceanic event is associated with a fluctuation of a global-scale tropical and subtropical surface pressure pattern called the Southern Oscillation. This coupled atmosphere-ocean phenomenon, with preferred time scales of two to about seven years, is collectively known as the El Niño-Southern Oscillation (ENSO).

The process by which people gain control over the factors and decisions that shape their lives. It is the process by which they increase their assets and attributes and build capacities to gain access, partners, networks and/or a voice, in order to gain control.

The institutional, policy and governance responses to create enabling conditions to implement direct responses or actions on the ground to halt land degradation or to restore degraded lands.

Enabling conditions are defined as conditions that facilitate approaches to addressing social and ecological challenges. They can be defined as factors that increase the likelihood of an intended change in the governance approach, strategy, or management regime. The presence of enabling conditions can facilitate the emergence of a particular environmental policy, whereas the absence of key enabling conditions can present a barrier to management or sustained policy action.

A species at risk of extinction in the wild.

Plants and animals that exist only in one geographic region.

The ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere.

Drivers that can be influenced by a particular policy or decision context, and are therefore regarded as endogenous or policy- relevant”. (Section 1.3.2.2).

Access to clean, reliable and affordable energy services for cooking and heating, lighting, communications and productive uses.

A.The uninterrupted availability of energy sources at an affordable price; B.The association between national security and the availability of natural resources for energy consumption within nation states. Long-term measures to increase energy security often center on diversifying energy sources.

Primary energy sources take many forms, including nuclear energy, fossil energy -like oil, coal and natural gas- and renewable sources like wind, solar, geothermal and hydropower. These primary sources are converted to electricity, a secondary energy source.

The positive effect resulting from an activity or program on environmental service flows.

Naturally occurring living and non-living entities of the Earth, together comprising the bio-physical environment, that jointly deliver ecosystem services to the benefit of current and future generation.

The facilitation of an integrated perception of the problems of the environment, enabling more rational actions capable of meeting social needs to be taken.

The environmental envelope of a species is defined as the set of environments within which it is believed that the species can persist: that is where its environmental requirements can be satisfied (see niche). Many large-scale vegetation or species models are based on environmental envelope techniques.

Environmental governance, as a subclass of the broader governance concept, has been defined as “the set of regulatory processes, mechanisms and organizations through which political actors influence environmental actions and outcomes” (Lemos & Agrawal, 2006), and it “should be understood broadly so as to include all institutional solutions for resolving conflicts over environmental resources”.

Environmental characteristics that explain the distribution of organisms and ecosystems in terms of environmental tolerances.

The potential occurrence of a natural or human-induced physical event or trend or physical impact that may cause loss of life, injury, or other health impacts, as well as damage and loss to property, infrastructure, livelihoods, service provision, ecosystems and environmental resources. In this report, the term hazard usually refers to climate- related physical events or trends or their physical impacts.

A measurable change to the properties of an ecosystem by a nonnative species. The logical implications of this definition are that (1) every nonnative species has an impact simply by becoming integrated into the system, (2) such impacts may be positive or negative and vary in magnitude on a continuous scale, and (3) impacts can be compared through time and across space.

A formal, evidence-based procedure that assesses the economic, social, and environmental effects of public policy or of any human activity.

An assessment that assesses the impacts of planned activity on the environment in advance, thereby allowing avoidance measures to be taken: prevention is better than cure.

An extraction from non-cultivated sources: natural forests, other non-forest wildlands such as grass-, bush- and wetlands, fallows, but also wild plants and animals harvested from croplands.

The fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation and enforcement of environmental laws, regulations and policies.

Fair treatment and meaningful involvement of all people regardless of race, colour, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. Fair treatment means that no single group of people should bear a disproportionate share of the negative environmental consequences arising from industrial, governmental, or commercial operations or policies. Meaningful involvement means that: (i) people must have the opportunity to participate in decisions about activities that may affect their environment and/or health; (ii) the public's contribution can influence the regulatory agency's decision; (iii) the public’s concerns will be considered in the decision-making process; and (iv) the decision makers must seek out and facilitate the involvement of those potentially affected.

The hypothesis of an inverted U-shaped relationship between economic output per capita and some measures of environmental quality: as GDP per capita rises, so does environmental degradation. However, beyond a certain point, increases in GDP per capita lead to reductions in environmental damage.

A hypothesized relationship between environmental quality and economic development: various indicators of environmental degradation tend to get worse as modern economic growth occurs until average income reaches a certain point over the course of development.

A tax whose tax base is a physical unit (or a proxy of it) that has a proven specific negative impact on the environment. Four subsets of environmental taxes are distinguished: energy taxes, transport taxes, pollution taxes and resources taxes.

Animals living on or just above the seabed.

A professional network with recognized expertise and competence, and a claim for policy-relevant knowledge, in a particular domain (Haas, 1992).

Universal participation in terms of equality of all inquirers in access to information and knowledge. Disputes over meaning and importance, among powerful and powerless social groups, on what knowledge counts as true, valid and important in decision-making. The idea of epistemic injustice also relates to distributive unfairness in the distribution of epistemic or knowledge goods and services such as information or education.

Epistemology is the theory of knowledge. It is concerned with how we know what we know; in other words, it relates to methods for producing knowledge (their assumptions, methods, scope).

A disease outbreak affecting a species’ population at the same time.

Fair and impartial.

Equity comprises three interlinked dimensions: Distributive equity highlights the need to consider not just the allocation of benefits, but also of costs and risks. Decisions about distribution can be justified on the basis of equality, social welfare, merit or need. Procedural equity encompasses fairness in political processes and participation in decision-making. Contextual equity recognises the fact that the playing field is never level, but that people's capabilities and their access to resources and power determine the extent to which they are able to utilise procedural equity to determine the best distributive outcome for themselves.

Fairness of rights, distribution, and access. Depending on context, this can refer to resources, services, or power.

elimination/extirpation of an invasive alien species from a defined geographic area even in the absence of all preventive measures obviating the necessity for further control measures (Dowdle, 1998). The time period after which an invasive alien species can be considered eradicated depends on the species and location.

The ease with which a soil erodes, defined by its resistance to two energy sources: the impact of raindrops on the soil surface, and the shearing action of runoff between clods in grooves or rills.

Places identified with as having a high erosion potential.
