Strata’s glossary provides definitions for key concepts and describes how data is processed and presented. The definitions are derived from multidisciplinary perspectives in the literature, across scientific fields and applied climate security practices. The full glossary can be accessed through the link above. Key definitions to note are:

  • Climate-related security risks: Risks that can simultaneously undermine the security of humans, communities, states, the international system, the environment, and ecology as a consequence of changing climate patterns, and their impacts on biophysical and socioeconomic systems (SIPRI).
  • Hotspot: A location where there is a convergence of stresses, which may include climate, environment, vulnerability, peace and security stresses. A hotspot implies that further attention is required in that location. It does not mean that an event has occurred, nor does it imply any quantitative probability of anything occurring.
  • Stress: A natural or human-induced event (slow-onset or rapid-onset), trend or physical impact that may cause adverse effects to human security or the environment, or strain a system such as a local community or a state. Also referred to as a “hazard”. (Based on IPCC hazard definition)
  • Indicator: A quantitative (georeferenced) dataset used to monitor a natural or socio-economic characteristic. This is either a data layer itself, used directly, or is based on one or more data layers combined in some way. For example, “rate of deforestation” is an indicator calculated using data layers of forest cover and forest change.
  • Basket: A categorisation of indicators and/or indices according to sector, issue, or other logical or theoretically-defined grouping system. Strata categorises its indicators into three main baskets relevant to climate security: 1) Environment and climate; 2) Peace and security; and 3) Socio-economic vulnerability.
  • Threshold: The level of an indicator beyond which impacts are likely and/or action needs to be taken. Thresholds are generally set based on guidelines in scientific literature (e.g. heatwave is flagged when Maximum Apparent Temperature >41°C for at least 3 consecutive days). When no guidelines are available, they are calculated based on historical conditions. Details of how each threshold is calculated can be found in the technical documentation.
  • Vulnerability: The propensity of exposed elements (people or assets) to be adversely affected by a hazard, as determined by physical, social, economic or environmental factors or processes. (Based on CSM and UNDRR definitions)
