Analysing Climate Vulnerability
- Basic concepts for analysing climate vulnerability.
- Impacts• Coping Range• Vulnerability• Exposure• Sensitivity
- Impacts are the consequences of the changes in, and interactions between natural and human systems. A system’s resilience can be measured by the magnitude of damage it can tolerate and still autonomously return to its original state.
- Coping range is a system’s capacity to accommodate variations in climatic conditions from year-to-year. Also known as the vulnerability or damage threshold, it varies among systems and regions and may itself change, reﬂecting new technologies and information to a system or, conversely,a loss of knowledge and skills from a system.
- Vulnerability within the ﬁeld of climate adaptation reflects a combination of exposure and sensitivityto climatic risks, and also the adaptive capacity todeal with those risks.Both impacts and vulnerability may be reduced by adaptation
- Vulnerability is a product of exposure, sensitivity and adaptive capacity. The greater the exposure or sensitivity, the greater the vulnerability. However it is very important to note that adaptive capacity is inversely related to vulnerability. Thus, the greater the adaptive capacity, . . . . the lesser the vulnerability.
