Abstract The implementation of new groundwater tracer tests to the chalky karst plateau of the northwestern end of the Paris Basin, combined with a critical review of previous tracer test investigations, makes it possible to characterize the role of karsts in relation to many structural features. The impact of tectonic structures and lithology on the development and evolution of the karst networks is analysed. The consequences for drinking-water supplies and its protection are examined.

Abstract Since 1975, the European Commission has supported research in the field of radioactive waste management and geological disposal through the Euratom Research and Training Programme. During the first two community programmes (1975–85), the research activities focused on basic knowledge, feasibility and safety assessments of such geological disposal repositories. It was during this first decade of collaborative research activities that the site characterization, preliminary design studies and the application for authorization to construct the first underground research laboratory, the High Activity Disposal Experimental Site facility, took place.

Abstract It is imperative today to make geoheritage conservation an essential part of all environmental standards and operational procedures. This is because geoheritage conservation secures the preservation of in situ geoheritage elements especially in urban environments such as Auckland. Geoheritage in Auckland is strongly associated with both indigenous culture and textbook geology of monogenetic volcanism, and it can play an important role in hazard forecasting and risk mitigation. To date, there has been a lack of policy or any planning tools based explicitly on the current geopreservation inventory. Here, we present an approach to support policy making informed by a spatial multi-criteria analysis that has long been used in environmental decision-making, supported by multi-layer mapping. A systematic literature review was undertaken to define the most accepted assessment criteria used in geoheritage evaluation. We identified six criteria for the base spatial layers of our analysis, highlighting the most suitable areas for geoheritage conservation. For cultural conservation, we used available archaeological shape files, indigenous land ownership data and elevation data (the volcanic cones had multiple roles in the life of first settlers, the ancestors of the Māori). Geographic Information Systems (GIS) multi-objective land use planning is an effective procedure for achieving complex planning and preservation objectives. It allows for outcomes based on quality data and sound analysis while minimizing compromise and conflict between geoheritage, social and cultural values.

Abstract The Geological Survey of Canada (GSC) has been furthering the geoscientific understanding of Canada since its inception in 1842, the equivalent of seven generations ago. The evolution of the activities of the GSC over this period has been driven by evolving geographic, economic and political contexts and needs. Likewise, new technologies and evolving scientific methods and models shaped broadly the successive generations of GSC geoscience activities. The most recent GSC generation presented a mixed portfolio of large framework mapping geoscience programmes, and more targeted, hypothesis-driven geoscience research, and the development of decision support products for a range of government, industry and other stakeholders needs. Entering its eighth generation, the GSC and related organizations are embracing digital technologies for applications such as the evaluation of mineral resource potential, the evaluation of risks and the early warning of earthquakes. In order to do so, the GSC will need to develop new methods and systems in co-operation with other geological survey organizations, and target its data acquisition and research to further advance its ability to respond to the evolving needs of society to navigate geology through space and time, from the past to the present, and from the present to the future.

Abstract Geological survey was first set up in Malaysia in 1903 mainly to facilitate tin mining activities that were started in the 1820s. Nevertheless, upon merging with the Department of Mines to form the Department of Mineral and Geoscience Malaysia (JMG), and also in order to meet the changing national needs, the new department has become increasingly relevant to a wide range of important national issues that help improve the well-being of society and contribute to the socio-economic development, an aspect that this paper describes. The changing role of the department is well reflected by the department being listed as a member of more than 57 technical committees in the country in the field of land-use planning, groundwater-resources management and mitigation of hazards. As we advance into the future, the department needs to ensure it is capable of rendering a more holistic service covering a wider spectrum of geological and geoscience activities to cater for the ever-increasing demands from society, industries, stakeholders and the government. For that reason, the Geological Survey Act, 1974 is being revised to beef up and provide the necessary jurisdiction in line with the duties, responsibilities and roles played by the JMG.

Abstract The Geological Survey of Finland (GTK) has over 130 years of history in mapping and studying mineral resources and their sustainable use. This has resulted in a globally top-ranking geodatabase and profound knowledge of Finnish geology and mineral resources, and has had a crucial impact on the continuously developing mining and exploration business in Finland. The basic mandate of the GTK has remained the same, but the strategic focus and mode of operation have changed considerably to meet new demands. Today, the GTK plays a vital role in providing geoscientific expertise and specialist services for a wide range of stakeholders and commercial clients in government, the business sector, academia and the wider community, in Finland and internationally. The GTK is actively building new ways to co-operate with universities, research organizations and companies to support future development and to expand its own expertise. This is further supported by the proactive use of cutting-edge technologies, such as the geomaterials research infrastructure, which allows studies from the nanoscale up to kilotons for diverse applications of mineral materials. The GTK plans to further strengthen its role as a key player in the minerals sector innovation ecosystems with a focus on primary minerals, the circular economy, digital solutions and water issues, which are expected to be essential factors for sustainable development through the 2020s and beyond. The GTK's main challenge is to ensure the continuous enhancement and renewal of expertise, to adapt and respond to future opportunities.

Abstract State Geological Surveys (SGSs) in the USA play vitally important roles, providing sound, unbiased scientific information to each state and the nation. Although implementation of each survey's scientific programme has evolved differently, these organizations are often the principal drivers of economic development, and they consult on policies for protecting land and water, mitigating geologic hazards and promoting sustainable development. The SGSs are represented by the American Association of State Geologists. For more than 110 years, they have partnered with the federal government on important geoscience issues concerning topographic and geologic mapping, water, mineral and energy resources, and geologic hazards. These collaborations continue to develop and expand across multiple specialties, providing critical support to the SGSs. The future role of SGSs will depend on legislative decisions, contributions to research and development and scientific advancement, and ability to leverage support from existing and new collaborations with academia and with federal, state, county and municipal agencies. The Illinois State Geological Survey, one of the largest SGSs, has continually pursued relationships across geoscience sectors to develop a strong multidisciplinary scientific programme. Going forward, all SGSs will be challenged to develop an effective data stewardship programme to communicate with a diverse clientele.

Abstract GNS Science is New Zealand's geological survey with an applied earth science research focus yet without traditional government department accountabilities. As one of New Zealand's Crown Research Institutes established in 1992, GNS Science is owned by the New Zealand Government but has higher levels of self-determination, fiscal independence and impartiality than a government department. Securing competitive research funding and commissioned research is a business imperative and because of this the institute is able to respond and adapt to changing societal expectations. GNS Science can also influence outcomes based on its discretionary research investment. New Zealand's geological setting astride an active plate boundary attracts many international partners endeavouring to better understand geological processes in an accessible and logistically well-resourced natural laboratory. Partnerships like these substantially increase technological and financial resources and these enable diverse and often ambitious projects.
