Development of a Land-Use/Land-Cover Change Science Plan forthe International Global Change Community

9317844 TURNER参与全球变化研究的自然科学家需要改进土地覆盖变化的模型，因为土地覆盖在全球动态自然过程中发挥着作用。但是，如果不了解影响土地覆盖的土地利用，就不能充分模拟或预测土地覆盖的变化。因为土地的使用在很大程度上是人类活动的产物，社会科学家因此必须为改善对影响土地和其他资源使用的社会、政治和经济动态的理解做出贡献。认识到这些相互联系以及自然科学家和物理科学家共同努力解决这些重要问题的必要性，国际地质圈-生物圈计划（IGBP）和国际社会科学委员会（ISSC）赞助的国际全球环境变化人类维度计划（HDP）已同意赞助一个关于全球土地利用和土地覆盖变化的重点科学研究计划。该奖项将为核心规划项目委员会（CPPC）提供支持，该委员会正在代表IGBP和HDP制定正式的科学计划。科学计划将概述识别和划分各种“驱动力”改变土地利用和土地覆盖的常见情况的战略。它还将针对这些情况进行个案研究，并根据这些情况和个案研究构建全球土地利用和土地覆盖模式。该奖项将补充对克拉克大学CPPC办公室的支持捐款。它还将帮助支持三次国际会议，这些会议将使更广泛的科学界参与科学计划的制定。这项活动的最终成果将是一项正式的科学计划，以指导今后处理土地利用和土地覆盖变化的国际合作研究活动。＊＊＊

9317844 TURNER Natural scientists involved in global change research need improved models of changing land cover because of the role that land cover plays in dynamic natural processes across the globe. Land-cover change cannot be adequately modeled or projected, however, without an understanding of the land uses that affect land cover. Because land uses are largely the product of human activities, social scientists therefore must contribute to improvement in understandings of the social, political, and economic dynamics that affect the use of land and other resources. In recognition of these interconnections and of the need for both natural and physical scientists to work together to address these important problems, the International Geosphere- Biosphere Programme (IGBP) sponsored by ICSU and the international Human Dimensions of Global Environmental Change Programme (HDP) sponsored by ISSC have agreed to sponsor a focused scientific research program on global land-use and land- cover change. This award will provide support for a Core Planning Project Committee (CPPC), which is developing a formal science plan on behalf of IGBP and HDP. The science plan will outline strategies for identifying and demarcating common situations through which various "driving forces" alter land use and land cover. It also will develop case studies for these situations and frame global land-use and land-cover models based on these situations and case studies. This award will complement contributions for support of the CPPC office at Clark University. It also will help support three international meetings that will bring the broader scientific community into the development of the science plan. The final product of this activity will be a formal science plan to guide future international collaborative research activities dealing with land-use and land-cover change. ***
