Adjustment in natural or human systems in response to actual or expected climate stimuli and their effects, which moderates harm or exploits beneficial opportunities. There are various types of adaptation, including anticipatory, autonomous, and planned adaptation. 1*
The whole of capabilities, resources, and institutions of a country, region, community, or group to implement effective adaptation measures. 2*
Management that is responsive to, or even anticipatory of, changing functions of natural and human systems, evolving management purposes, and changing contextual conditions. This management approach acknowledges uncertainty, designing and implementing actions that are deliberately experimental and focused on learning from the effects of management. It emphasizes monitoring and participatory approaches as well.
Climate in a narrow sense is usually defined as the average weather or, more rigorously, as the statistical description of mean values and variability of variables such as surface temperature, precipitation, and wind over a period of time ranging from months to thousands or millions of years. Climate in a wider sense describes the state of the climate system.1*
Climate change refers to a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period.1*
Climate design values
Statistics pertaining to weather and climate events that inform engineering design criteria. These values include calculated return periods for extreme weather (such as intense rain, wind, snow, extreme cold, and freezing rain) of varying intensities and durations. Climate design values generally reflect historical conditions for a given geographical location, an approach that is challenging in a changing climate.
Command and control
A type of policy instrument that relies on regulation (permission, prohibition, standard setting, and enforcement) as opposed to financial incentives to achieve a policy outcome.3*
Physical and information-technology facilities, networks, services and assets that, if disrupted or destroyed, would have a serious impact on the health, safety, security, or economic well-being of a population or the effective functioning of governments.4
Social phenomenon resulting from the intersection of a hazard with a vulnerability that exceeds or overwhelms the ability to cope and may cause harm to the safety, health, welfare, property or environment of people.5
The interactive system formed from all living organisms and their physical and chemical environment within a given area. Ecosystems cover a hierarchy of spatial scales.1*
Ecologically distinct zones with characteristic plant and animal life and physical features.
A present or imminent event that requires prompt coordination of actions concerning persons or property to protect the health, safety or welfare of people or to limit damage to property or the environment. 5
The process whereby societies or organizations make important decisions, determine whom they involve, and how they render account.6
Incentives broadly refer to mechanisms that encourage or discourage certain types of behaviour. Incentives can include relevant information, price signals, regulations, and financial rewards or penalties. Provision of or access to these incentives can be design or unintentional.
The physical foundation of a society, community, or enterprise. Infrastructure comprises assets, installations, or systems used to provide goods or services.7
Rules and norms that guide how people within societies live, work, and interact. Formal institutions are codified rules, such as the constitution, organized markets, or property rights. Informal institutions are rules governed by social or behavioural norms of a family, community or society.8
A term encompassing trends in advanced economies toward greater dependence on knowledge, information and high skill levels, and the increasing need for ready access to all of these by the business and public sectors. 9
The integration of adaptation considerations (or climate risks) such that they become part of policies, programs, and operations at all levels of decision making. The goal is to make the adaptation process a component of existing decision-making and planning frameworks.10
In the context of climate change, mitigation is an intervention intended to reduce adverse human influence on the climate system; it includes strategies to reduce greenhouse gas sources and emissions and enhance greenhouse gas sinks. Mitigation in the context of disaster management refers to sustained actions taken to eliminate or reduce risks and impacts posed by hazards well before an emergency or disaster occurs.1*,5*
When the result of an initial process triggers changes in a second process that in turn influences the initial one. A positive feedback intensifies the original process, and a negative feedback reduces it.1*
Ground (soil or rock and included ice and organic material) that remains at or below 0C for at least two consecutive years.11
Duplication of critical components of a system in order to increase its reliability. As an example, buildings may be equipped with backup power generators to maintain essential services in case of power failure.
The ability of a social or ecological system to absorb disturbances while retaining the same basic structure and ways of functioning, the same capacity for self-organization and the same capacity to adapt to stress and change.1
A combination of the likelihood (probability of occurrence) and the consequences of an adverse event (e.g., climate-related hazard).10
A systematic approach to setting the best course of action under uncertainty, by applying management policies, procedures and practices to the tasks of analyzing, evaluating, controlling and communicating about risk issues.12
In the context of climate change and other global change drivers, security is more than protection of territory or national interests. Human security, for example, means protecting people from critical and pervasive threats and situations, building on their strengths and aspirations, through strategies of protection and empowerment. 13*
A person or an organization that has a legitimate interest in a project or entity, or would be affected by a particular action or policy.1
Residue of raw material or waste separated out during the processing of crops or mineral ores. 14
A cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with their environment.15
Vulnerability to climate change is the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change, including climate variability and extremes. Vulnerability to climate change is a function of the character, magnitude, and rate of climate variation to which a system is exposed, as well as its sensitivity and its adaptive capacity.1*
State of the atmosphere at a given time and place with regard to temperature, air pressure, humidity, wind, cloudiness and precipitation. The term is mainly used to describe conditions over short periods of time.16
