The last decades have witnessed the development and implementation of several early warning systems initiatives to help communities in the developing world reduce their vulnerability to extreme weather events and long-term climatic changes. These initiatives have been supported by governments, NGOs and international organizations. However, research has already shown that many of the root causes of vulnerability to these events are linked to complex socioeconomic, political and cultural aspects, entrenched in processes of marginalization, lack of resources, assets and power. So, in this sense, what are the limits of early warning systems and the risks of using them as major components of climate change adaptation strategies? Does anyone have literature to suggest on early warning systems and climate change adaptation in this context?
Adaptation is a continuous process and occurring in repose of changes, therefore, for immediate remedial measure, the early warning system may be a major components, however, for longer perspective, it may not be.
However, against disaster or extreme events, EWS may be a potential tool and thus may be the major one for developing the capability and saving the resources and casualties.
Installation of an early warning system was one of short-term responses to Climate Change Vulnerability Assessment for City of Sihanoukville, Cambodia. More can be found here http://www.fukuoka.unhabitat.org/programmes/ccci/pdf/CMB1_Sihanoukville-web.pdf
As I understand, it was not a major component, but was an affordable, relatively simple, early response to the report. This is in accordance with Risk Management theory and principles, you may wish to refer to the ISO standard and other literature on RM.
early warning system for climate change will not be very useful. However, if the early warning system is for the disaster management this is essential and can be linked indirectly to climate change phenomena.
