Physical, chemical and biological parameters of aquatic ecosystems are negatively affected by extreme climatic events. The resulting effects include impairment of system health and the decrease or loss of ecosystem services, which has environmental, economic and social implications. To mitigate these negative outcomes, lake and reservoir resilience must be increased. This will require assessing the parameters affected and the severity of the impairment.
Implementation of high frequency monitoring for numerous physical, chemical and biological characteristics will obtain data before, during and after extreme events. Analysis of the collected information can provide insight to the relationship of extreme climatic events and ecosystem functionality loss. Complementary socioeconomic valuation of ecosystem services can elucidate the social and economic loss associated with degraded aquatic systems. The combined knowledge acquired from these environmental, economic and social investigations will develop a holistic assessment of the water bodies. From this understanding, an adaptable framework can be developed with an aim to inform management decisions on steps for increasing resilience and maximizing socioeconomic value.
