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.”
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.
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
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
