U.S. Participation in GCTE Focus 3 Conference "Food & Forestry-Global Change and Global Challenges" (Sept. 20-23, 1999) to be held at the University of Reading, UK

abstractscherm99——09831——美国。该项目将支持美国的4名资深科学家和3名青年科学家参加与定于1999年9月20日至23日在英国雷丁举行的全球变化和陆地生态系统（GCTE）粮食和林业会议有关的讲习班。讲习班的题目是：农业集约化对微量气体排放的影响；在区域尺度上连接生态系统和经济模式；开发或修改作物生产模式以模拟全球变化下病虫害造成的损失。会议的目标是为两个广泛的领域制定研究议程：1)增加粮食、纤维和燃料供应的环境后果，以及2)气候变化对生产系统和环境退化的影响。特别是，组织者希望更有效地关注生态系统——特别是农业生态系统——与全球变化要素之间的相互作用。

AbstractScherm99-09831U.S. Participation in GCTE Focus 3 Conference "Food and Forestry - Global Change and Global Challenge"This project will support U.S. participation by four senior scientists and three early-career scientists in workshops associated with the Global Change and Terrestrial Ecosystems (GCTE) conference on food and forestry to be held in Reading, England on 20-23 September 1999. The workshops are entitled:o Effect of agricultural intensification on trace gas emissionso Linking ecosystem and economic models at regional scaleo Developing or modifying crop production models to simulate losses due to pests and diseases under global change.The conference objective is to develop research agendas for two broad areas: 1) the environmental consequence of increasing food, fiber and fuel supply, and 2) the affect of climate variability on production systems and environmental degradation. In particular, the organizers wish to bring a more effective focus on the interactions between ecosystems - particularly agroecosystems - and elements of global change.
