  • Environmental Science Environment Science InterrelatednessReintroduce Wolf who eat the Elk  increased Willow tree >increased beavers & songbirds change in water flow, change in ecosystems and biodiversity
  • Ecosystem Approach Ecosystem  System, scale, boundaries, interactions  Earth  Forest  Lake  Area of pines (Pine Forest)  Open water  Area of oaks (Oak Forest)  Shallow bottom areas  A river running through it  Deep bottom areas  Under a rock in the river  Salt marsh  A Beaver pond in the middle  Vegetated areas  Desert  Streams or canals  Coral reefs  Islands  Shores  Rivers  In-land forest
  • Ecosystem Approach: Political vs.Environmental BordersMekong River Basin China, Myanmar, Thailand, Laos, Cambodia, Vietnam  Industry  Power generation  Transport  Municipal water supply  Agricultural irrigation  Fishing 1995 Mekong River Commission  Thailand, Laos, Cambodia, Vietnam  Downstream effects View slide
  • Science vs. Policy  Small artificial wetland system—1750  Keoladeo National Park, India, 1982  Endangered Siberian Cranehttp://whc.unesco.org/pg.cfm?cid=31&id_site=340 http://www.pbase.com/dbehrens/image/874479 View slide
  • Global Nature of Environmental Problems 1992, Earth Summit  United Nations Conference on Environment and Development (UNCED)  Sustainable Development  Biodiversity 1997, 125 nations  Kyoto Conference on Climate Change,Kyoto protocol  Greenhouse gases —reduce to 5% of 1990 levels between 2008-2012 2007, Intergovt’l Panel on Climate Change (IPCC)—4th Assessment Report“Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level”
  • Global Nature of Environmental Problems 2005, The Millenium Ecosystem Assessment  Supporting Services  Photosynthesis, soil formation, nutrient cycling, water cycling  Provisioning services  Resources such as food, fiber, genetic resources, natural medicines, freshwater  Regulating services  Activities that affect air quality, water flow, erosion control, water purification, climate control, disease regulation, pest regulation, pollination, natural hazards  Cultural services  Spiritual, religious, aesthetic values & recreational uses  Negative comments overall
  • Environmental Programs (--no, don’t memorize) Global  UN Environmental Programme (UNEP)  International Environmental Education Programme (IEEP)  World Health Organization (WHO)  The Network on Environment and Development Co-operation  Organization for Economic Co-operation and Development (OECD) North America  US Environmental Protection Agency  Environment Canada
  • Environmental Programs (--no, don’t memorize) UAE??  UAE Federal Environmental Agency  Environment and Protected Areas Authority (EPAA), Sharjah  Bee’ah, Sharjah’s Environmental Company—s  Dubai Municipality & Abu Dhabi Environmental Agencies  Emirates Center for Strategic Studies and Research (ECSSR)  Emirates Wildlife Society/ World Wide Fund for Nature (EWS-WWF)
  • Wilderness North Much of Alaska and Northern Canada “Wilderness” - areas with minimal human influence Generally in areas with severe climate or undeveloped countries UAE—Remote areas w/o human influence??
  • Agricultural Issues UAE—Greening of the dessert  Non-point source pollution  Irrigation UAE  Historically grazing was nomadic  Over-grazing  Exotic plants  Irrigation Sustainable agriculture
  • Environmental Issues Resolving environmental conflicts takes compromise  Both sides of every issue need to be considered Yes/no, good/bad, guaranteed, definite. . . Do not exist“Never say never or always, there are always exceptions, such as this one.”
  • Summary Environmental science  Study of the environment, humanities place in it, and humanities impact on it  Involves science, economics, ethics, politics and more, in arriving at solutions to environmental problems Ecosystem Approach  Because ecosystems do not coincide with political boundaries, a regional approach to solving environmental problems is ideal.  This should use natural borders rather than political ones
  • Each region of the world has certain environmental issues that are of primary concern because of the mix of population, resource use patterns, and culture.  What was the most significant environmental issue of 2011?  What are some specific issues to do with the GCC countries?
