  1. Earth Science Vision 2010 – 2025Ecosystems, Biosphere, and Human-Biosphere Interactions Ecological Forecasting “… to observe and understand Earth’s biosphere, to enable the prediction of ecological changes that affect the quality of life on Earth.”

  2. NASA’s Earth Science Vision • NASA’s Earth Science Vision for 2025 calls for significant advances in our ecological forecasting capabilities * • What is an ecological forecast? An ecological forecast predicts the impacts of biological, chemical, and physical changes on ecosystems, ecosystem components, and people ... * See IGARSS ’01 Paper by Smith, Wickland, Crawford, Cihlar, and Schnase entitled Advancing our Biological and Ecological Predictive Capabilities.

  3. Ecosystem Goods and Services • Ecosystems are the basis of a strong economy • Goods - Annually, US ecosystems provide: • $3.9 Billion in commercial fishing revenues • $206 Billion from agriculture • 20 Billion cubic feet of timber • The base of strong recreation and tourist industry • Services - Ecosystems also provide: • Clean air and water for every citizen • Detoxification and decomposition of toxins • Cycling and movement of carbon and nutrients • Drought and flood mitigation

  4. Ecosystem Goods and Services • To sustain their delivery, we have to: Understand how they are produced naturally … • Biogeochemical cycles • Trophic dynamics • Species interactions • Abiotic drivers • Abiotic-biotic interactions … and how they are affected by change

  5. Principal Scales of Change

  6. Interacting Drivers of Change
