All major climate-change agenda efforts in recent years echo the need for more empirical
scientific information about climate change and adaptation to freshwater ecosystem impacts. The
adaptation research undertaken in this study begins the process of providing answers to the
general question posed by resource managers and other stakeholders, “What options can we
choose from to ensure the sustainability of the aquatic resources under our stewardship?” More
specifically, the research results in a systematic methodological framework which resource
managers could build on to determine adaptation options for specific lake types, as well as
examples with respect to such options.
