Multi-disciplinary approaches to water systems:introduction to the special column

作者：Steven RFASSNACHT,Mingguo MA

摘要：1 Introduction As the human population grows,the livelihoods and well-being of a significant portion of humanity will depend even more on the ability of freshwater ecosystems to provide essential services(V?r?smarty et al.,2010),which will require the maintenance of biodiversity in these freshwater systems(Dudgeon et al.,2006).There are many competing demands on the available water resources,such as potable water,fish and wildlife habitat,agriculture,industrial use,and recreation,that are driven by different sectors;even within a specific sector there can be diverging interests.For example,water management of the Upper Arkansas River in Colorado has been mandated by the 1949 Arkansas River Compact between the US states of Colorado and Kansas which has led to stream-aquifer issues(Taylor and Luckey,1974),water transfers from agriculture to urban(Howe et al.,1990),and competing recreational uses(Wollmuth et al.,1985;Arkansas Basin Roundtable,2017).The recent Upper Arkansas Voluntary Flow Management Program tries to balance many users,including recreation by kayakers and rafters who want to maintain streamflow(at the Wellsville gauge)at or greater than 20 m3/s as well as anglers who want lower flows in the range of 7 to 11 m3/s to maintain fish habitat(Arkansas Basin Roundtable,2017).
