★ [U06-07] Toward a new seamless science for a detection of terrestrial ecosystem responses under changing climate
Keywords:Carbon cycle, Global warming, Terrestrial ecosystem, Global monitoring
Studies on ecosystem change in the global and continental scales have been conducted using satellite remote sensing and ecosystem process models to bring meaningful predictions and suggestions. Now more reliable verification of such predictions and direct detections of actual changes in ecosystems are required based on long-term ground observations. A major difficulty is that it needs a very long-term, highly comprehensive, and consistent monitoring that covers productivity, decomposition, nutrient cycle, plant invasion, changes in species composition, succession, etc.
In this presentation, recent studies on global warming effects in terrestrial ecosystems will be reviewed, and progress on carbon budget estimations based on integrated observing and analysis systems are introduced. In particular, such projects as "The US National Ecological Observatory Network" (NEON; http://www.neoninc.org/) and "Integrated Carbon Observation System" (ICOS; http://www.icos-infrastructure.eu/) in Europe are introduced to discuss future needs of long-term, consistent, and operational ecosystem monitoring to detect changes in ecosystems and biogeochemical cycles due to climate change.
