Abstract The present special publication addresses opportunities and challenges in meeting the demand for essential and critical metals and minerals needed to supply the green and sustainable societies of the future. The notion of criticality in different countries is discussed and examples of ongoing national and cross-country research and mapping programmes are presented. In addition to the resource/reserve and technical–economic aspects, the social and environmental dimensions are also elaborated in some of the contributions, as holistic approaches to the exploration and exploitation of critical minerals and materials are needed to fulfill the green transition and goals for the Green Stone Age.

Abstract This volume is a collection of papers authored by senior managers and heads of Geological Survey organizations (GSOs) from around the world in an attempt to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs face an uncertain future and need to understand global trends. Whereas population trends are somewhat predictable, societal responses to change are much less so and technological change is fundamentally disruptive and chaotic. As countries adopt sustainable development principles and the public becomes increasingly (but not necessarily reliably) informed about environmental issues using social media, the integration of resource development and environmental stewardship becomes increasingly important. GSOs will continue to provide key information about Earth systems, natural hazards and climate change in this context. This introduction comprises a short review of the global trends affecting GSOs, a snapshot of the state of GSOs, examples of how GSOs are adapting their activities to the modern world, including the growing use of big data, and an examination of international collaboration between GSOs. The time is perhaps ripe to reinforce international collaborations through a global network of GSOs. To achieve this will require leadership and a focus on the big picture of global sustainability.

Abstract Social development and rapid growth in the world's population has followed a remarkable technological development the past hundred years. Revolutions in agriculture and industry, medical innovations and new production technologies, have led to an increased standard of living for a larger part of the Earth's population. Megatrends for future developments are lining up and predictions for the next 40 years are numerous. Most ideas about our future societies imply new and innovative geo-scientific achievements. Towards 2058, we will have virtually surveyed and mapped every corner of the Earth. We will have detailed 3D images of the urbanized areas, and 4D models to assist to make reliable forecasts in a world of increased pressure on the natural resources and changing ecosystems. By 2058 the Green Stone Age is established, and we will use all elements in the periodic system and more rare minerals to support new materials and technological solutions. The major energy supplies will be CO 2 free. The agriculture will be more efficient, distribution and consumption of food will be more rational, and we will harvest from more marine food chains than today. More than 70% of the people on Earth will live in megacities and urban areas. Our cities will become smarter and greener, cars and public transport will be self-driving and autonomous tools using artificial intelligence to automate functions previously performed by humans. Substantial resources will be used to repair damaged ecosystems, and most important, we will use materials and products that have fewer negative consequences for the environment. The 17 UN goals for sustainable development are guidelines into the future, and geological surveys should serve as key instruments in the transformation into smarter and more sustainable societies. We are already on our way providing critical minerals for low carbon energy solutions, marine knowledge for blue growth, plans for green and smarter cities, and advanced digitalization for public services, as shown by examples in this present paper.

Abstract A holistic understanding of the oceans as part of the Earth system is imperative for the future management and sustainable utilization of the ocean's natural resources. Increasing pressures on global resources have been accompanied by important advances in acoustic remote sensing technologies, allowing us to map the seabed in unprecedented detail. The MAREANO (Marine areal database for Norwegian waters) programme in Norway, one of the world's largest seabed mapping programmes, is designed to close the knowledge gaps with the use of the new technologies. To date, since the start in 2005, c. 1170 million NOK (Norwegian kroner), equivalent to c. US$115m have been allocated to this programme (2005–20). This paper outlines the development of MAREANO and other large marine mapping and science programme proposals in Norway, and considers which factors influenced whether they were realized or not. In conclusion, funding of MAREANO came as a result of the convergence of political needs, technical capacity and multi-institutional co-operation. We further give an overview of the new and improved seabed mapping technologies, and finally we discuss the Norwegian programmes in connection with similar major international ongoing programmes and new initiatives and take a look at possible advances in future seabed mapping.
