  1. Reducing Land Based Sources of Marine Ecosystem Problems CCICED Roundtable Meeting April 27-28, 2011

  2. Determinants of Ecosystem Health • Water Quantity • Water resource availability • Upstream diversions • Upstream consumptive uses • Variability in precipitation • Water Quality • Upstream discharges • Municipal and industrial • Agricultural nonpoint sources • Development and use of coastal lands

  3. Agriculture in China’s Rural Economy(gross output value 100 million yuan)

  4. Efficiency in Agriculture Enhances Resilience of Food Supply System • Water conservation – saves water supply for additional water use in the future, reduces costs • Precision nitrogen fertilizer use – protects local water supplies, reduces costs • Livestock manure management – utilizes nutrients, protects local water supplies

  5. Digesters Produce Fuel, Reduce GHG Emissions, and Lower Local Air & Water Pollution 沼气项目

  6. Water, Biomass, & Nutrient Management in Rice Production Reduces GHG, Conserves Water, Lowers Pollution, Saves Money水稻田项目

  7. Precision Nitrogen Application Reduces GHG Emissions, Lowers Water Pollution, Saves Money 测土施肥 Test the Soil !!

  9. Potential GHG Reductions

  10. Scenarios for Agricultural GHG Reductions in China 中国农业温室气体减排情景分析 Source: CCICED Task Force on Rural Economy, Environment and Climate Change, 2009 来源： 国合会农村经济，环境和气候变化工作组，2009

  11. Low Carbon Transit Card 低碳交通卡

  12. Conclusions 结论 • The new urgency and stringency of environmental targets under the 12th Five Year Plan require a renewed focus on policy efficiency and specific implementing mechanisms 十二五规划将提出更严格更急迫的环境目标，这要求决策者重新审视政策的效率 • Integrated policy frameworks can achieve multiple goals simultaneously 综合政策框架可以同时实现多个目标 • The examples shown illustrate how environmental protection policies can promote “inclusive growth” and increase incomes例证展示了环保政策如何促进“共享式增长” • AND reduce land based sources of pollution to protect the ecosystem services of rivers and the sea
