Water-Soil-Vegetation Dynamic Nexuses and Human Rectifications in Changing Climate

Session ID#: 74261

Session Description:
Water-soil-vegetation nexuses affect, and are affected by, both human activity and climate change. For a given area, inappropriate land and water management practices can result in soil and vegetation degradation, which in turn will likely alter natural hydrologic processes, leading to more frequent and severe flooding and drought, which in response tends to prompt soil erosion, causing further vegetation degradation or even loss. Such nexuses likely become more interwoven in changing climate because the non-stationary climate can further deteriorate the already-altered hydrology. As one of the most successful engineering measures to water management, reservoirs may be wisely operated to rectify such unwanted alternations. To date, our understanding is incomplete regarding how to maintain such nexuses in terms of eco-environmental resilience. We cordially invite presentations of original experimental and modeling studies that address interrelations between hydrologic alteration and soil and/or vegetation with climate change and reservoir operation as possible additional factors.
