CRVA METHODOLOGY

Set Up

Explore the concepts and methods behind the CRVA process and understand how it can be applied to local, regional and national levels in the Central Asia region.  Get insight on how to bridge climate exposure and risk with meaningful, actionable adaptation interventions. 

Indicators

 

The set up of the CRVA starts with choosing appropriate indicators for assessment requests. A good indicator has to be:

  • Valid and relevant
  • Precise
  • Affordable
  • Reliable and credible
  • Practical
  • Allowing data acquisition in the future
  • Clear in direction
  • Appropriate

Most climate change impacts are driven by several climate indicators which have different magnitude of influence on the climate change impacts. Those indicators having the strongest relation with the impact are the key indicators. These are mostly not the common indicators like average temperature and precipitation, but rather indicators related to extremes that are changing at a different rate than the averages and show the potential climate change impact more accurately than the indicators related to averages. The key indicators are therefore more useful to assess than others in relation to risk and vulnerability assessment and in line with that with the planning of adaptation capacity.
