Summary This workshop was primarily motivated by the goals of the International Decade for Natural Disaster Reduction (IDNDR), one of which is that each country should have a comprehensive national assessment of risks due to natural hazards by the year 2000. It was sponsored by the Environmental Adaptation Research Group (EARG) of Environment Canada, the International Partnerships of Environment Canada, the Geological Survey of Canada, Emergency Preparedness Canada and the Canadian National Committee of the IDNDR. The National Science Foundation of the U.S. and the Government of Mexico supported travel costs related to their delegates. The workshop dealt with both atmospheric hazards such as tornadoes and floods, and geological hazards such as earthquakes and landslides. Nine U.S., eight Mexican and 24 Canadian participants included academia, government and the private sector. Six projects were selected as being of joint interest to all three countries, with lead country and agencies identified for possible future cooperative work.  相似文献

This paper summarizes the target areas for research which will plug gaps in knowledge concerning the windstorm hazard, and initiatives which will improve preparedness, protection and recovery. Part I refers to strategic planning aspects and Part II outlines the character of windstorm damage, the ingredients of disaster, and a research agenda.The international character of both the windstorm hazard itself as well as many of the means for mitigating this hazard give the IDNDR, through the UN, unique advantages and opportunities. Among these are: the UN's current involvement with many aspects of the wind storm problem including World Weather Watch and Disaster Relief as well as the UN's accessibility to many Third World development programmes.Many national and international, governmental, professional and research communities are already hard at work improving the understanding of the wind storm hazard and providing the knowledge base on which advances can be made. This work will continue. The IDNDR will be a catalyst in changing attitudes and in achieving objectives which would otherwise be greatly more difficult.This paper was presented to the ad hoc Committee of Experts, UN Steering Committee for International Decade for Natural Disaster Reduction (IDNDR) held in Geneva, 6 July 1988. The views expressed are the author's and are not the official views of the UN Steering Committee.  相似文献

美国全球变化研究的法律基础   总被引:1,自引:0,他引:1  
自1990年以来,美国全球变化研究计划(USGCRP)已经实施了10多年,并取得了丰硕的成果,这在很大程度上归因于相对完善的法律体系。一方面,《1990年全球变化研究法案》全面协调该计划在国内和国际的实施,使计划在实施的10年里获得了大量的基础科学数据和丰富的研究成果;另一方面,美国《信息自由法》、《版权法》及相关数据政策促进了全球变化研究数据和信息的共享,避免了在获取科学数据方面的重复建设,提高了数据的使用效率。在全球变化研究法案的强制要求下,美国的全球变化研究计划稳定发展、不断完善。  相似文献

国际全球变化研究发展态势文献计量评价   总被引:1,自引:0,他引:1  
全球变化研究是国际上地球系统综合研究的重大跨学科研究领域.随着全球环境问题的日益突出,国际上先后组织发起了全球环境变化研究的四大科学计划WCRP、IGBP、IHDP、DIVERSITAS及其组成的地球系统科学联盟ESSP,开展对全球变化和地球系统科学的研究.当前,全球变化问题不仅是科学界关注和研究的问题,也是政治界、经济界都关注的重大问题.科技文献能够反映科学前沿的发展动态.对SCIE和SSCI数据库收录的全球变化研究文献进行统计,从文献计量学的角度,分析国际全球变化研究领域的发展态势,了解中国全球变化研究的国际影响力.可以看出:国际上全球变化研究的论文数量一直呈增长趋势,以地球科学多学科、生态学、环境科学、自然地理学、植物学等学科领域为主.中国自2000年以来在该领域的发文数量增长较快,特别是中国科学院的发文量已进入国际前列,但中国在该研究领域尚缺少高影响力的论文.  相似文献

Scientific outreach, international networking, collaboration and adequate courses are needed in both developed and developing countries to enable early-career hydrogeologists to promote long-term multidisciplinary approaches to cope with climate-change issues and emphasize the importance of groundwater in a global strategy for adaptation. One such collaboration has involved the Early Career Hydrogeologists’ Network of the International Association of Hydrogeologists (ECHN-IAH) and the UNESCO International Hydrological Programme’s (IHP) Groundwater Resources Assessment under the Pressures of Humanity and Climate Changes (GRAPHIC) project. This collaboration seeks to foster the education and involvement of the future generation of water leaders in the debate over groundwater and climate change.  相似文献

Geological research on the Mediterranean region is presently characterized by the transition from disciplinary to multidisciplinary research, as well as from national to international investigations. In order to synthesize and integrate the vast disciplinary and national datasets which are available, it is necessary to implement maximum interaction among geoscientists of different backgrounds. The creation of project-oriented task forces in universities and other research institutions, as well as the development of large international cooperation programs, is instrumental in pursuing such a multidisciplinary and supranational approach. The TRANSMED Atlas, an official publication of the 32nd International Geological Congress (Florence 2004), is the result of an international scientific cooperation program which brought together for over two years sixtythree structural geologists, geophysicists, marine geologists, petrologists, sedimentologists, stratigraphers, paleogeographers, and petroleum geologists coming from eighteen countries, and working for the petroleum industry, academia, and other institutions, both public and private. The TRANSMED Atlas provides an updated, synthetic, and coherent portrayal of the overall geological-geophysical structure of the Mediterranean domain and the surrounding areas. The initial stimulus for the Atlas came from the realization of the extremely heterogeneous nature of the existing geological-geophysical data about such domain. These data have been gathered by universities, oil companies, geological surveys and other institutions in several countries, often using different procedures and standards. In addition, much of these data are written in languages and published in outlets that are not readily accessible to the general international reader. By synthesizing and integrating a wealth of preexisting and new data derived from surficial geology, seismic sections at various scales, and mantle tomographies, the TRANSMED Atlas provides for the first time a coherent geological overview of the Mediterranean region and represents an ideal springboard for future studies.  相似文献

The international journal Landslides was initiated in April 2004. It is the core project (IPL-C100) of the International Programme on Landslides, a joint initiative of the International Consortium on Landslides and the United Nations and other global organizations. The aims of Landslides are to promote landslide sciences, technology, and capacity building and strengthen global cooperation for landslide risk reduction within the United Nations International Strategy for Disaster Reduction. This paper presents an analysis of the first 5 years of Landslides, the study methods employed, the types and major causes of landslides, the number of different contributors per country, and the “times cited” per issue and most frequently cited papers and briefly discusses some of these. Strategies for future development of the journal involve obtaining input and suggestion from researchers and readers worldwide.  相似文献

The Swiss National Network for the Observation of Isotopes in the Water Cycle (NISOT) includes eleven precipitation, seven surface water (river) and three groundwater stations, where tritium, deuterium and oxygen-18 are monthly measured in composite samples. The network provides a good overview of the characteristic isotope signatures in recharge waters in Switzerland and of the relations between isotopes and altitude, orography and the amount of precipitation. Mixing of air water vapour and surface waters can be observed along a NW/SE cross section through the Alps. With increasing length of the data series, the network provides a valuable contribution for national and international scientific and practical applications in surface and subsurface hydrology, climatology and biology. The Swiss Geological Survey at the Federal Office for Water and Geology operates the isotope network within the legal framework of the Federal Law on the Protection of Waters and guarantees quality, access and distribution of the isotope data.  相似文献
