Fifteen years after the term ‘ecohydrology’ came into use to describe integrative research spanning the two parent disciplines, we discuss methodological traditions of the parent disciplines and assess trends in the methodologies utilized in the young hybrid field of ecohydrology. In particular, we explore whether the marriage between the disciplines is built on a marriage of methodological str...

The process of learning in social-ecological systems is an emerging area of research, but little attention has been given to how social and ecological interactions motivate or inhibit learning. This is highly relevant to the South African water sector, where a major policy transition is occurring that provides local water users and managers with new opportunities to engage in adaptive learning ...

Currently the world’s airspace is being operated at the limits of both capacity and safety by different stakeholders. Various initiatives worldwide are investigating future air traffic management concepts. A shift towards trajectory-based environments is identified, where user needs and performance capabilities are leading to user preferred routing by using Airborne Separation Assistance System...

Climate-related changes in glacierized watersheds are widely documented, stimulating adaptive responses among the 370 million people living in glacier-influenced watersheds as well as aquatic and riparian ecosystems. The situation denotes important interdependencies between science, society, and ecosystems, yet integrative approaches to the study of adaptation to such changes remain scarce in b...

The hydrological characteristics of biological soil crusts (BSCs) are not well understood. In particular the relationship between runoff and BSC surfaces at relatively large (>1 m(2)) scales is ambiguous. Further, there is a dearth of information on small scale (mm to cm) hydrological characterization of crust types which severely limits any interpretation of trends at larger scales. Site diffe...

The concept of green hydropower needs an evaluation procedure for the ecological upgrading of hydropower plants based on scientific criteria [1]. For the planning and evaluation of riverrestoration programs, concepts like “ecosystem integrity” or “river health” have been proposed and empirically tested. Computer programs have been developed, which allow the testing of alternative restoration co...
