9530225 Tiessen The network to be established concerns biogeochemical cycles in semi-arid tropical ecosystems and derived agricultural systems. It aims at the establishment of a research center for researah, training and education from existing links between three research institutions in Canada, Brazil and Venezuela, and an expansion of these links within Brazil and to Bolivia and Mexico. The phase I proposal is for a workshop to bring together present and future participants of the network, assemble present knowledge (and gaps) on the interactions of biogeochemical cycles and vegetation; unify research and training approaches, and prepare a Phase II proposal. The workshop will be a short course on soil-vegetation interactions in the biogeochemical cycling of important nutrient elements, and on the nutrient and climatic limitations to plant production in the semiarid regions. The material presented is to be collated in a form suitable for training and education material for participants and their institutions. This will serve as an example of the capacity building activities which will accompany the research of the IAI Phase II Proposal. In addition, common research approaches will be formulated, and there will be planning for an exchange of researchers and teachers establish the network to be supported by Phase II. The longer term goal is for this network proposed for Phase II to be extended to form an IAI Research Consortium. The network to be established concerns biogeochemical cycles in semi-arid tropical ecosystems and derived agricultural systems. The phase I proposal is for a workshop to bring together present and future participants of the network, assemble present knowledge (and gaps) on the interactions of biogeochemical cycles and vegetation; unify research and training approaches, and prepare a Phase II proposal. The goal of the Phase II proposal is the establishment of a research network, with the aim of facilitating terrestrial ecosystems research with a strong prac tical component, that may serve as a tool for planning and guidance for sustainable land use related to agriculture and watershed management. In addition, the PIs hope to create a network for training and education, improve the research and teaching capacities of the institutions involved, and provide a focus for investigations with importance to the envionmentally sound management of large areas of the South American semi-arids. This proposal involves researchers from three research institutions in Canada, Brazil and Venezuela, and it plans an expansion of its links within Brazil and to Bolivia and Mexico. The proposed collaboration will play a role in the provision of vital ecosystem understanding. In addition, findings on the interaction of trees and soil fertility will be examined with the aim to establish a data base on fertility-biology interactions, with relevance for the use of indigenous species of agroforestry. The above mentioned countries are Member States of the IAI, an initiative to stimulate cooperative research on global change issues among the scientific institutions of the Americas. The National Science Foundation is the designated U.S. Government Agency to carry out the U.S. responsibilities within the IAI. ***

小行星9530225 拟建立的网络涉及半干旱热带生态系统和由此衍生的农业系统的生物地球化学循环。 该项目的目的是利用加拿大、巴西和委内瑞拉三个研究机构之间的现有联系，建立一个研究、培训和教育中心，并将这些联系扩大到巴西境内以及玻利维亚和墨西哥。 第一阶段的建议是举办一次研讨会，将网络的现有和未来参与者聚集在一起，汇集关于生物地球化学循环和植被相互作用的现有知识（和差距）;统一研究和培训方法，并编写第二阶段的建议。 讲习班将是一个短期课程，内容是重要营养元素的地球化学循环中土壤-植被的相互作用，以及半干旱地区植物生产的营养和气候限制。 所提供的材料将以适合于学员及其机构的培训和教育材料的形式加以整理。 这将作为能力建设活动的一个例子，这些活动将伴随着IAI第二阶段提案的研究。 此外，还将制定共同的研究方法，并将规划研究人员和教师的交流，以建立第二阶段支持的网络。 长期目标是将第二阶段拟议的网络扩展到形成IAI研究联盟。 拟建立的网络涉及半干旱热带生态系统和由此衍生的农业系统的生物地球化学循环。 第一阶段的建议是举办一次研讨会，将网络的现有和未来参与者聚集在一起，汇集关于生物地球化学循环和植被相互作用的现有知识（和差距）;统一研究和培训方法，并编写第二阶段的建议。 第二阶段提案的目标是建立一个研究网络，目的是促进具有强有力的实用成分的陆地生态系统研究，这可以作为规划和指导与农业和流域管理有关的可持续土地利用的工具。 此外，研究所希望建立一个培训和教育网络，提高有关机构的研究和教学能力，并提供一个重点调查，对南美洲大片半干旱地区的环境无害管理具有重要意义。 这项建议涉及加拿大、巴西和委内瑞拉三个研究机构的研究人员，并计划扩大其在巴西境内以及与玻利维亚和墨西哥的联系。 拟议的合作将在提供重要的生态系统理解方面发挥作用。 此外，还将审查关于树木与土壤肥力相互作用的研究结果，目的是建立一个肥力-生物相互作用数据库，以便利用当地农林业物种。 上述国家是国际影响研究所的成员国，该倡议旨在促进美洲科学机构之间就全球变化问题开展合作研究。 国家科学基金会是指定的美国政府机构，在IAI内履行美国的责任。 ***
