ERE1.2

Europe is facing a number of societal challenges that are firmly linked to subsurface resources: groundwater, geo-energy and raw materials. Our society needs economic wealth and the use of resources is fundamental to this, while at the same time a healthy and secure environment for all citizens needs to be ensured. The growing population and the demographic change add to the pressure on surface and subsurface resources and uses. Moreover, the industrial transformation envisaged by the EU will increase the need for coordinated subsurface research and innovation underpinned by reliable and easy access to subsurface data.
In order to support such transition, integrated European subsurface knowledge, development and sharing of improved processes and the use of new innovative technologies throughout the value chain will be essential. The Geological Survey Organisations of 32 countries within Europe laid the cornerstone to this achievement by establishing the GeoERA Programme. GeoERA’s main objectives to contribute to the more integrated and efficient management and more responsible exploitation and use of the subsurface are in line with several United Nations Sustainable Development Goals.

This session will address integrated European geoscience services that will provide advice and data to Europe towards a sustainable subsurface management, integrating geo-resources (energy, water, raw materials) and environmental conditions (energy storage, natural hazards, anthropogenic impacts, biodiversity, climate change mitigation and adaptation), supported by a cross-thematic online information platform.

ERE1.4

Over the course of the last years, the Environmental Crisis has been persistendly deepening. Recent research in the field of Geosciences has been focusing on finding good solutions for making mitigating the crisis. However, the economy of most resources-based and fossil fuel-based technologies are based on a linear paradigm which has a detrimental effect on the Environment. To protect, preserve and restore the environment and make it flourishing again, research in the field of geosciences should be based on a new geo management paradigm which implies new economic models and business concepts. Green-economy, bio-economy, and smart and circular economy, are the most recent models that have proven to lead to a more sustainable development. Are they competing or supplementing each other? What opportunities do the most recent model of smart circular economy bring to Environmental protection? How does it reshapes or is going to reshape the entrepreneurial and management mentality? What business concepts may constitute a core of the new geo management paradigm? How do Circular City projects contribute to a new Geo management paradigm shaping by becoming its laboratories?
This session welcomes any contribution that demonstrates new geo management paradigm that leads to sustainable development while preserving the beauty of our natural resources.

ITS5.4/CL3.4

Understanding the impact of climate change on natural and socio-economic outcomes plays an important role in informing a range of national and international policies, including energy, agriculture and health. Economic models of climate impacts used to guide policy rely on multiple components: projections of future climate change, damage functions, and policy responses, each of which comes with its own modelling challenges and uncertainties.

We invite research using process-based (e.g. Integrated Assessment Models) and empirical models of climate change to investigate future impacts, together with policy evaluation to explore effective mitigation, technology and adaptation pathways. Furthermore, we invite research on changes to, and new developments of climate-economic and econometric modelling.

ITS5.1/CL3.6

Remaining carbon budgets specify the quantity of CO2 that can be emitted before a given warming level (such as the 1.5 °C target) is reached, and are thus of high interest to the public and policymakers. Yet, there are many sources of uncertainty which make it challenging to deduce this finite amount of CO2 emissions. The theoretical foundation of carbon budgets is based on the concept of the Transient Climate Response to cumulative CO2 Emissions (TCRE). This is the pathway-independent ratio of global warming per unit of cumulative CO2 emissions. However, accounting for non-CO2 forcings and changes in albedo or other Earth system feedbacks provides further challenges in calculating TCRE and the remaining carbon budgets.

This session aims to further our understanding of the climate response under different emission scenarios, and to advance our knowledge of associated carbon budgets consistent with meeting various levels of warming. We invite contributions that use a variety of tools, including fully coupled Earth System Models, Integrated Assessment Models, or simple climate model emulators. We welcome studies exploring different aspects related to carbon budgets and the TCRE framework, including: the governing mechanisms behind linearity of TCRE and its limitations, effects of different forcings and feedbacks (e.g. permafrost carbon feedback) and non-CO2 forcings (e.g. aerosols, and other non-CO2 greenhouse gases), estimates of the remaining carbon budget to reach a given temperature target (for example, the 1.5 °C warming level from the Paris Agreement), the role of pathway dependence, the climate-carbon responses to different emission scenarios (e.g. SSP scenarios, or idealized scenarios), and the behaviour of TCRE in response to artificial CO2 removal from the atmosphere (i.e. negative emissions). Contributions from the fields of climate policy and economics focused on applications of carbon budgets are also encouraged.

ITS5.2/AS3.17

Accurate and precise atmospheric measurements of greenhouse gas (GHG) concentrations reveal the rapid and unceasing rise of global GHG concentrations due to human activity. The resulting increases in global temperatures, sea-level, glacial retreat, and other negative impacts are clear. In response to this evidence, nations, states, and cities, private enterprises and individuals have been accelerating GHG reduction efforts while meeting the needs of global development. The urgency, complexity and economic implications of GHG reductions demand strategic investment in science-based information for planning and tracking emission reduction policies and actions. In response, the World Meteorological Organization (WMO) Global Atmosphere Watch Program (GAW) and its partners have initiated the development of an Integrated Global Greenhouse Gas Information System (IG3IS). IG3IS combines atmospheric GHG concentration measurements and human-activity data in an inverse modeling framework to help decision-makers take better-informed action to reduce emissions of greenhouse gases and pollutants that reduce air quality. This service is based on existing and successful measurement and analysis methods and use-cases for which the scientific and technical skill is proven or emerging.

This session intends to gather presentations from researchers and decision-makers (user-community) on the development, implementation and use of atmospheric measurement-based “top-down” and data-driven “bottom-up” GHG emission inventory estimates, and the combination of both approaches, explicit in space and time, to deliver actionable emissions information at scales where human activity occurs and emission reduction is most effective. This session will also showcase the new projects and efforts to develop “good-practice” standards under the World Meteorological Organization (WMO) Integrated Global Greenhouse Gas Information System (IG3IS), which is part of WMO’s commitment to science-based services.

ERE2 – Renewable energy

ERE2.1

Wind and solar power are the predominant new sources of electrical power in recent years. Portugal’s renewable energy production in March 2018 was 104% of its electricity demand in the same month. By their very nature, wind and solar power, as well as hydro, tidal, wave and other renewable forms of generation are dependent on weather and climate. Modelling and measurement for resource assessment, site selection, long-term and short term variability analysis and operational forecasting for horizons ranging from minutes to decades are of paramount importance.

The success of wind power means that wind turbines are increasingly put in sites with complex terrain or forests, with towers extending beyond the strict logarithmic profile, and in offshore regions that are difficult to model and measure. Major challenges for solar power are notably accurate measurements and the short-term prediction of the spatiotemporal evolution of the effects of cloud field and aerosols. Planning and meteorology challenges in Smart Cities are common for both.

For both solar and wind power, the integration of large amounts of renewable energy into the grid is another critical research problem due to the uncertainties linked to their forecast and to patterns of their spatio-temporal variabilities.

We invite contributions on all following aspects of weather dependent renewable power generation:

• Wind conditions (both resources and loads) on short and long time scales for wind power development, especially in complex environments (e.g. mountains, forests, coastal or urban).
• Long term analysis of inter-annual variability of solar and wind resource
• Typical Meteorological Year and probability of exceedance for wind and solar power development,
• Wind and solar resource and atlases.
• Wake effect models and measurements, especially for large wind farms and offshore.
• Performance and uncertainties of forecasts of renewable power at different time horizons and in different external conditions.
• Forecast of extreme wind events and wind ramps.
• Local, regional and global impacts of renewable energy power plants or of large-scale integration.
• Dedicated wind measurement techniques (SODARS, LIDARS, UAVs etc.).
• Dedicated solar measurement techniques (pyranometric sensors, sun-photometer, ceilometer, fish-eye cameras, etc.) from ground-based and space-borne remote sensing.
• Tools for urban area renewable energy supply strategic planning and control.

ERE2.2

This session addresses spatial and temporal modelling of renewable energy systems, both in a prospective as well as in a retrospective manner. Therefore, contributions which model the characteristics of future renewable energy systems are equally welcome as contributions which assess the characteristics of the past performance and characteristics of renewable energies. Session contributions may reach from purely climate based assessments of simulated renewable generation time series to full energy system models used to better understand energy systems with high shares of renewables.

Studies may for instance
- Improve our understanding of how climate data can be used to model renewables
- Show the spatial and temporal variability of renewable energy sources
- Assess the complementarity of different renewable energy sources or locations
- Derive land availability scenarios for renewable energies based on climatic, technical, economic, or social criteria
- Assess past performance of renewables
- Assess past spatial deployment patterns of renewables
- Derive integrated scenarios of energy systems with high shares of renewables

The objective of the session is to provide an insight into recent advances in the field of renewable energy system models. The session welcomes papers dedicated to climatic and technical issues, policy-making, forecasting and real time applications concerning renewable energy systems.

This year we are also publishing a special issue in the ISPRS International Journal of Geo-Information for the session.

ERE2.3

There is a global need for low carbon energy, and marine renewable energy could make a significant contribution to reducing greenhouse gas emissions and mitigation of climate change, as well as providing a high-technology industry. Marine renewable energy includes offshore wind, wave, tidal range (lagoons and barrages), and tidal-stream energy, as well as technologies such as ocean thermal energy conversion, salinity gradients and desalination. Understanding the environment these marine renewable energy devices are likely to operate in is essential when designing efficient and resilient devices. Accurate characterisation of the resource is of clear importance, whilst interactions with the environment, and between other “blue economy” developments, is essential for the development of the industry and marine spatial plans. Indeed, synergies exist when considering the sustainable use of the ocean’s energy, such as multi-purpose platforms integrating marine renewable energy devices and aquaculture.
This session is designed to share information on new research techniques and methods to better understand the resource and the environment, including mapping tools, numerical modelling approaches, and observations. We welcome contributions that will further the development of the blue economy: for example, resource characterization, design considerations (e.g. extreme and fatigue loadings), and environmental impacts. The session will also include studies of impacts, from physical and biological, to societal interactions (e.g. effects to tourism). Research areas are envisaged to include but not restricted to: modelling and quantification of the interaction of the device to the marine environment (e.g. changes in hydrodynamics) as well as on the biology directly; cumulative impacts of large and multiple developments (potentially of differing technologies or marine stressors); new technologies for quantification; management of space; collision; noise.

HS5.3.2

The transition to a low-carbon economy will require the development of innovative methods to integrate renewable sources of energy while minimizing the additional pressure on closely connected ecosystems.

Hydropower is a mature and cost-competitive renewable energy source, which helps stabilize fluctuations between energy demand and supply. Depending on the relative capacities of the intermittent renewables and hydropower facilities, integration may require changes in the way hydropower facilities operate to provide balancing, reserves or energy storage. Moreover, non-power constraints on the hydropower system, such as irrigation water deliveries, environmental constraints, recreation, flood control and variable social acceptance tend to reduce the ability of hydropower to integrate variable renewable.

This session solicits contributions that describe, characterize, or model distributed renewable energy sources at different spatial and temporal scales that are relevant for planning and management of electricity systems. Special attention will be devoted to the interactions between the energy-water system and the climate and hydrological variables that govern production in space and time. Of particular interest are case studies and other contributions of hydrology and power grid modernization initiatives to understand these complex interdependencies. The development of new modeling approaches to analyze interactions with climate-policy and power grid management options, socio-economic mitigation measures and land use are welcome.

Questions of interest include:
- How to predict water availability for hydropower production?
- How to predict and quantify the space-time dependences and the positive/negative feedbacks between wind/solar energies, water cycle and hydropower?
- How do energy, land use and water supply interact during transitions?
- What policy requirements or climate strategies are needed to manage and mitigate risks in the transition?
- Quantification of energy production impacts on ecosystems such as hydropeaking effects on natural flow regimes.

This session has the support of the European Energy Research Alliance (EERA) that established the joint program “Hydropower” to facilitate research, promote hydropower and enable sustainable electricity production. Further information can be found here:

ERE2.6

With an increasing demand for low-carbon energy solutions, the need of geothermal resources utilization is accelerating. Geothermal energy can be extracted from various, often complex geological settings, e.g. fractured crystalline rock, magmatic systems or sedimentary basins. Current advancements also target unconventional systems (e.g., Enhanced Geothermal Systems, super-hot, pressurized and co-produced, super-critical systems) besides conventional hydrothermal systems. Optimizing investments leads to the development of associated resources such as lithium, rare earths and hydrogen. This requires a joint effort for monitoring, understanding and modelling geological systems that are specific to each resource.
A sustainable use of geothermal resources requires advanced understanding of the properties of the entire system during exploration as well as monitoring, including geophysical properties, thermo-/petro-physical conditions, fluid composition; structural and hydrological features; and engineering challenges. Challenges faced are, among others, exploration of blind systems, reservoir stimulation, induced seismicity or related to multiphase fluid and scaling processes.

The integration of analogue field studies with real-life production data, from industrial as well as research sites, and their organization and the combination with numerical models, are a hot topic worldwide. With this session we aim to gather field, laboratory and numerical experts who focus their research on geothermal sites, to stimulate discussion in this multi-disciplinary applied research field. We seek for contributions from all disciplines, ranging from field data acquirements and analysis to laboratory experiments, e.g. geophysical surveys or geochemical experiments, and from the management and organization of information to numerical models as well as from (hydro)geologists, geochemists, (geo)physicists, surface and subsurface engineers.

ERE2.7

Characterisation of geothermal energy systems requires advanced understanding of the dominant processes and properties of the geothermal systems. The aim of this session is to offer a platform to present and discuss the use of modeling, analogue and numerical, for the development of geothermal energy. Theoretical, observation, experimental, analogue, and numerical models offer the support to the development of concept and applications to achieve a sustainable and efficient recovery of geothermal energy. All methods have their strength and offer the possibility to develop the understanding of specific aspects of the geothermal system.
All enthalpies of geothermal energy systems can be considered for this session, from new development in small-scale systems to supercritical and from ATES to EGS. The characterization of the geometry of the system, flow and transport properties of main conductive paths and fluid-rock interaction mechanisms and of course heat structure are example of the studies that will be central to this session. Multidisciplinary and multi-scale are most welcome to stimulate the discussion and share/exchange ideas and promote future collaborations within the community.
We invite speakers to present their original research work on theoretical/mathematical models, computer simulation and other experimental/observational aspects. Potential topics include, but are not limited to:
(1) Advanced mathematical models of coupled multi-physical (e.g., mechanical, thermal, hydrological and chemical) processes in geothermal systems based on equivalent continuum, double-porosity, and discrete fracture models.
(2) Lab and field experiments of coupled T-H-M-C processes involved in geothermal production.
(3) Integration of experimental data into numerical models for site characterization, experimental design, data interpretation and uncertainty quantification
(4) Utilization of numerical tools for risk assessment and prediction of potential impacts
(5) Advanced numerical methodologies and models to investigate the hydraulic fracturing process in geothermal systems.

ERE2.10

A large-scale introduction of renewable energy systems (RES) is vital for climate mitigation in emission pathways keeping global temperature stabilization well below 2°C in 2100. At the same time, the United Nations have proposed 17 Sustainable Development Goals (SDGs) to address society’s common global challenges. Among these, increasing human well-being by ending poverty and hunger (SDG 1&2) while at the same time delivering affordable and clean energy (SDG 7), protecting biodiversity (SDG 14&15) and mitigating climate change (SDG 13) are key.

There is an increasing need to assess possible synergies and trade-offs between climate change mitigation and across different SDGs from different RES. A global large-scale introduction of RES may increase the pressure on land resources, including food production systems and other ecosystem services. Land use management is at the core as the effects of introducing different RES on SDGs may vary dependent on spatial location and scale of implementation. Identifying RES deployment strategies that co-deliver across multiple SDGs is vital.

We encourage abstract submissions linking RES deployment to one or more SDGs. In this context, a variety of methods, models and tools are of interest. Examples of these include environmental analyses, life cycle analyses, land use management, regional climate modelling, earth system modelling, energy system models, policy relevant analyses, GIS applications, integrated assessment etc.

ERE4 – Geo-storage

ERE4.1

Storage of energy and carbon dioxide in subsurface geological formations has been identified as key for future systems relying on renewable, zero carbon power and heat generation. All subsurface storage systems rely on the properties and integrity of the reservoir and its confining units under thermal, mechanical, hydraulic and chemical stress. Natural analogues have provided evidence for the feasibility of long-term containment of methane and carbon dioxide in geological formations and may offer similar insights for energy and heat storage.

This session addresses storage of fluids in geological systems at all scales, from laboratory experiments to full-scale storage projects. Individual studies, initiatives and active projects integrating elements of the storage chain are invited as well as field projects focused on geological storage. Managed aquifer recharge is also within focus if the stored water is used in an energy context.

Relevant topics include but are not limited to:

ERE4.2

The successful implementation of safe deep geological disposal of spent fuel, high-level waste and other long-lived radioactive waste is one of the currently most pressing environmental challenges in several countries worldwide. Site exploration and assessment are primarily geoscientific tasks that require interdisciplinary collaboration of different geoscientific disciplines, like geophysics, hydrogeology, (hydro-)geochemistry, mineralogy, geomechanics, and geological as well as THMC modelling. Successful and socially accepted site selection and implementation, however, not only depend on geoscientific state-of-the-art results and R&D programs but to a large extent on well-designed public outreach and public involvement/participation activities as well as on suitable regulatory frameworks.
As for other subsurface technologies such as the storage of thermal energy and other energy carriers, or the deposition of chemotoxic waste, barrier integrity is a crucial aspect for the assessment of nuclear waste disposal. Different technical concepts in diverse geological candidate formations are being discussed. Numerical simulations, in conjunction with experimental studies are an integral part of safety and environmental-impact assessment concepts involving barrier integrity as a key component. Reliable comparative analyses of potential technological options require coupled THMC models capturing the particularities of each rock type and associated repository concept to a comparable level of sophistication. Structural as well as process complexity are often met by data scarcity and variability, necessitating the treatment of uncertainties and variability.
Aside from geoscientific and technological aspects this interdisciplinary session also addresses social and regulatory challenges by welcoming contributions from research and technical support organizations, waste management organizations, regulatory bodies, and NGOs. The session provides a platform for the exchange of i) geophysical, geochemical, geotechnical knowledge for assessing the integrity of multi-barrier systems considering equally conceptual, theoretical, computational and experimental aspects as well as ii) safety assessment strategies and tools, disposal concepts, national and transnational public outreach and involvement programs, siting approaches and relevant regulatory frameworks. Presentations related to other subsurface technologies that face comparable challenges are also welcome.

GI2.8

The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).

The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relation with human and non-human biota. The topic also involves hazard prediction and nowcast technology.

By combining 34 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 9 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.

The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(e) Forestry;
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability, countermeasure);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).

The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.

ERE5 – Raw materials

ERE5.1

At present, constructional geomaterials make the largest (by volume) group of extracted mineral raw materials. Despite their low unit price, they significantly contribute to the economy in many senses. Ongoing worldwide development of infrastructure, rapid urbanisation and the need for maintenance of the existing structures exert enormous pressure on the environment due to the extraction of new materials from natural resources, along with their processing and transportation.
The resources, processing, testing, and proper use of construction geomaterials thus deserve attention from the scientific community due to their long-term use, importance for the society, and sensitivity to the environment. As our knowledge of many aspects of these materials is still rather limited, the session aims to focus on the following topics:
• characterisation of traditional raw materials and their products, such as natural and dimension stone, aggregates (crushed stone, sands and gravels), inorganic binders (lime, natural cements and hydraulic limes), bricks, clay, earth and adobe;
• use of geomaterials in concrete and service life of such materials;
• recovery of historic knowledge of constructional geomaterials processing and use;
• assessment of durability;
• comparison of natural and anthropogenic decay of constructional geomaterials, the role of human impact on their service life;
• study of interactions and material compatibility between traditional construction materials and modern restoration products;
• conservation of geomaterials in heritage structures;
• availability of traditional materials in modern society, including comparative studies between small-scale production of materials (e.g. natural cement) and large-scale industrial processing;
• use of local materials as a part of cultural and/or industrial and technical heritage;
• technological properties and their testing;
• on site and laboratory standardized (ASTM, EN, etc.) and non-standardized testing techniques and their limitations for constructional geomaterials’ characterization;
• geological evaluation of geomaterials’ deposits;
• compositional and genetic aspects influencing extraction, processing, and utilization of constructional geomaterials;
• use of quarry waste, utilization of stone extraction and processing by-products;
• environmental issues.

Natural stones are integral part of the architectonic heritage built over the centuries and thus reflect close cultural affiliation with society. Our session deals with Heritage Stones defined explicitly by the IUGS Sub Commission on Heritage Stones (HSS). We promote recognition of natural stones that have achieved an important and significant use in human culture. The session is open to discuss the use of heritage stones in different civilizations over the period of time, their impact on human culture, geoheritage, geoarchaeology and architectonic relevance. The session is also open to discuss current scenario on status of the architectonic heritage in terms of their deterioration and steps to reinforce restoration of the same, in addition to aspects such as historical quarries, quarry landscape and trade of these heritage stones etc.
Global Heritage Stones constitute a resource of great social and economic relevance that attracts cultural tourism, and form an important link to understand the geology and history of a region. Global Heritage Stone recognition will promote public and policy-maker interest in stonebuilt heritage, encourage the use of natural stones and ensure the availability of stones required for maintenance and restoration of built heritage. It will also assist in forming a broader understanding of how the usage of the most traditional building material has evolved over centuries to the present-day application. As factory produced building materials took over in the last two centuries or so, architects seem to be re-evaluating their choices and there is a reawakened interest in the usage of stone as a contemporary building material.
This session is promoted by the Heritage Stones Subcommission (HSS), an IUGS subcommission within the International Commission on Geoheritage (ICG). The proposed session encourages contributions related to above sub themes from all over the world.
Selected contributions from our previous EGU sessions are published in high impact factor journals, such as: Geological Society of London Special Publications (SP407: Global Heritage Stone: Towards International Recognition of Building and Ornamental Stones), Episodes Special Issue on Heritage Stones (volume 38-2, June 2015), Geoscience Canada (volume 43(1), March 2016), Geoheritage (2018), Episodes (in process of publication by 2020). Selected contributions of EGU 2020 will be considered for publication in a special issue of a well rated journal.

ERE5.4

Mineral resources are used in larger quantities than ever before in history, and are the basis of our modern society. The safe and sustainable supply of mineral resources is fostering a demand for innovative actions to cover the foreseeable future industry and human demands. Exploration is the first step in the mineral resources cycle. On one hand, most of the giant deposits at shallow depths have been already explored and mined out and the industry is moving towards deeper and more complex mineral systems, which brings significant exploration challenges. On the other hand, the exploration sector needs time-saving, cost-effective, and, particularly in Europe, environmentally friendly and socially acceptable techniques to ensure sustainable access to mineral resources.
This session aims to bring together geoscientists from various (e.g. remote sensing, geochemistry, geology, geophysics, modelling, mineralogy, structural geology) involved in mineral exploration for the 21st Century. Abstract submissions for this session can include, but are not limited to, the following topics: new methods of exploration; imaging; conceptual modelling and quantification of deposits and mineral systems; cost reduction in exploration; non-invasive exploration; integration of multidisciplinary methodologies and datasets; scale-up and replicability; industry-academia synergies and FAIR data repositories.

ERE5.5

Assessing and mitigating the environmental impacts of solid waste is critical to develop sustainable waste management strategies. Solid waste deposits from the extractive industry, i.e. extractive waste (EW), and municipal solid waste (MSW) landfills can be an environmental threat through groundwater or surface water contamination in addition to the human health risks they might pose. Furthermore, MSW landfills account for 5% of the anthropogenic methane production worldwide.
In line with Europe’s Circular Economy Action Plan, several strategies emerged aiming for sustainability regarding the use of natural resources, a responsible consumption/production, dynamic landfill management (DLM) and, mainly for EW, the recovery/reuse of waste produced during exploitation and processing activities. These include the reduction of emissions through control of microbial activity, sustainable mining and recovery of raw materials and energy, the rehabilitation of the occupied land among others. Yet, the controlling mechanisms of microbial activity and other degrading processes in waste are largely unknown, and traditional methods based on the analysis of samples generally lack the required resolution for an adequate characterization of biogeochemical processes. Hence, there is a big demand of innovative techniques for the characterization and monitoring of EW and MSW disposal sites. In particular, reliable information about the composition and geometry of waste depositions, as well as about their biogeochemical status is needed. Geophysical methods are well suited to fulfill these requirements as they can provide real-time information about subsurface physical properties in a non-invasive way and with high resolution in space and time.
The main topics to be discussed in this session deal with the use of innovative methods, including, but not limited to, geophysical approaches for:
- Characterization and monitoring of MSW and of EW from quarries and mines.
- Case studies for the detection and assessment of environmental pollution associated to the disposal of solid waste.
- Evaluation of the risks associated with the management of waste and integrated approaches towards sustainable mining,
- Innovative technologies to exploit EW facilities and to improve the systematic recovery of waste flows. Case studies related to the recovery of EW from quarrying and mining activities, including valorization as construction materials.

Mineral deposits represent principal sources of metallic and non-metallic raw materials for our society. The implementation of new climate policies and the rise of green energy production and use will trigger an unprecedented demand increase for such resources. Formation of economic commodities requires component sequestration from source region, transport and focusing to structural or chemical barriers. These enrichment processes typically involve magmatic, hydrothermal, weathering or metamorphic events, which operate in diverse geodynamic settings and over various time scales. The scope of this session is to collect insights from diverse areas of mineral exploration, field, analytical or experimental studies of mineral deposits as well as resource characterization and extraction. We invite contributions from fields of economic geology, mineralogy and geochemistry in order to advance our understanding of ore-forming systems.

ERE6 – Process coupling and monitoring related to geoenergy applications

ERE6.1

Modelling of geological subsurface utilisation in terms of chemical or thermal energy storage as well as hydrocarbon production and storage are required to ensure a safe and sustainable energy supply. However, utilisation of the geological subsurface may induce changes in the recent hydraulic, thermal, mechanical and chemical regimes. Our session aims at the integration of experimental and numerical modelling methods for quantification and prediction of the potential impacts resulting from geological subsurface utilisation including:
• Site characterisation and determination of site-specific geological and process data.
• Development of static geological models.
• Integration of experimental data into static and dynamic models as well as application of numerical models for experimental design and interpretation.
• Development and benchmarking of modelling tools.
• Model and parameter upscaling techniques.
• Model coupling addressing the interaction of thermal, multi-phase flow, geochemical and geomechanical processes in the fluid-rock system.
• Application of modelling tools for site characterisation and prediction of potential impacts.
• Methods for risk assessment and efficient site operation.

Numerous cases of induced/triggered seismicity have been reported in the last decades, directly or indirectly related to anthropogenic activity for the geo-resources exploration. Induced earthquakes felt by local population can often negatively affect public perception of geo-energies and may lead to the cancellation of important projects. Furthermore, large earthquakes may jeopardize wellbore stability and damage surface infrastructure. Thus, monitoring and modeling processes leading to fault reactivation, (seismic or aseismic) are critical to develop effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected fluids, subsurface geology, stress interactions, and resulting induced seismicity requires an interdisciplinary approach that accounts for coupled thermo-hydro-mechanical-chemical processes to understand the triggering mechanisms.
In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal-energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modeling, the spatio-temporal relationship between seismic properties, injection/extraction parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

ERE6.3

Fractures are discontinuities in rocks that are present in almost all geological settings and at any scale. They may represent small-scale fissures or build up large scale faults. Fractures are extreme forms of heterogeneities, often with a small extension but huge impact.
The presence of fractures modifies the bulk physical properties of the original media by many orders of magnitudes, and they often introduce a strongly nonlinear behavior. This refers in particular to the mechanical properties via reduction of strength and stiffness. Fractures also provide the main flow and transport pathways in hard rock aquifers, dominating over the permeability of the rock matrix, as well as creating anisotropic flow fields and transport. Understanding their hydraulic and mechanical properties of fractures and fracture networks thus are crucial for predicting the movement of any fluid such as of water, air, hydrocarbons, or CO2. Consequently, fractures are of great importance in various disciplines such as hydrogeology, hydrocarbon reservoir management, and geothermal reservoir engineering.
The geologist toolbox to explore and model fractured rocks is getting more and more extended. This session is dedicated to novel ideas and concepts on treating the challenges related to the generic understanding, the characterization and the modelling of fractured geological media.
Contributions are welcome from the following topics
• Exploration methods for mechanical and/or hydraulic characterization of fractured media
• Structural construction of fractured media by deterministic or stochastic approaches,
• Representation of static hydraulic and/or mechanical characteristics of fractured media involving continuous or discontinuous methods,
• Simulation of dynamic processes and the hydraulic and/or mechanical behavior of fractured media,
• Theoretical studies and field applications in fractured geological formations,
• Concepts of accounting for fractured properties specifically in groundwater, petroleum or geothermal management applications.

HS8.1.4

Dissolution, precipitation and chemical reactions between infiltrating fluid and rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often leads to the formation of intricate patterns: networks of caves and sinkholes in karst area, wormholes induced by the acidization of petroleum wells, porous channels created during the ascent of magma through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: dissolution of carbonate rocks by CO2-saturated water can reduce the efficiency of CO2 sequestration, mineral scaling reduces the effectiveness of heat extraction from thermal reservoirs, acid rain degrades carbonate-stone monuments and building materials.

With the advent of modern experimental techniques, these processes can now be studied at the microscale, with a direct visualization of the evolving pore geometry. On the other hand, the increase of computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore-scale.

We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale. We also invite contributions from related fields, including the processes involving coupling of the flow with phase transitions (evaporation, sublimation, melting and solidification).

HS3.3

Society today demands sustainable technical solutions that reconcile the needs of society with those of nature . These solutions must coordinate between different and often competing demands within a sub-system (irrigation, ecological flow, power generation) and the variety of different uses of environmental resources across systems (e.g., power from water, wind, sun, or waves). The short term variability of precipitation, wind speed, sunshine, and other for environmental resources create a need for complex decisions to be taken in real time. Advances in real-time automatic control will play an essential role in making this possible. Moreover, while one might debate whether or not stationarity is dead, it is clear that fully deterministic models cannot cope with the connected world of today. The complex interactions of the randomness in the availability and quality of different resources calls out for an at least partially stochastic modelling approach.
We particularly invite contributions on:
• Stochastic modelling and control;
• Real-time control of environmental systems;
• Real-time monitoring and control of water quality;
• Real-time control of rural water systems;
• Real-time control of urban water systems.

Recent advances in deformation sensing have led to new applications in various geophysical disciplines such as earthquake physics, broadband seismology, volcanology, seismic exploration, strong ground motion, earthquake engineering and geodesy.
New developments in translation, rotation and strain sensing enable the complete observation of seismic ground motion and deformation. Applications are manifold, ranging from the reduction of nonuniqueness in seismic inverse problems to the characterization, separation and reconstruction of the seismic wavefield.
Among others, fibre optic technologies is bound to become a standard tool for crustal exploration and seismic monitoring thanks to: (i) easier installation (low cost, simpler installation and maintenance, robustness in harsh environment); (ii) high spatial and temporal resolution over long distance; (iii) broader frequency band. There have been significant breakthroughs, applying fibre optic technologies to interrogate cables at very high precision over very large distances both on land and at sea, in boreholes and at the surface.
These developments overlap with considerable improvements in optical and atom interferometry for inertial rotation and gravity sensing which has led to a variety of improved sensor concepts over the last two decades.
We welcome contributions on theoretical advances and applications of novel sensing methodologies in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal investigations, etc. including laboratory studies, large-scale field tests and modelling.

We are happy to announce Nathaniel J. Lindsey as invited speaker.

HS8.2.12

Hydraulic, thermal, chemical and mechanical processes (coupled or uncoupled) in saturated media are of increasing interest in many hydrogeological contexts and their understanding is a major challenge in modern hydrogeology. These processes play a major role in natural systems, such as in thawing rock and soil and volcanic environments, but also in anthropogenic systems where human activities are intensifying the pressure on groundwater and subsurface space use. The understanding of these processes is of paramount importance to:
• Ascertain the role of groundwater in the context of geothermal energy and mitigating its impacts. It is also needed to consider the seasonal and long-term development of thermal and mechanical conditions in aquifers, heat transfer across aquifer boundaries and between fluid and rock are focus points, and the influence of precipitated fluid compounds.
• Enhance the development of underground constructions improving its efficiency and minimizing impacts.
• Achieve an accurate characterization of subsurface flow, transport and heat transfer, which require observations of induced or natural variations of the thermal regime. There are many ongoing research projects studying heat as a natural or anthropogenic tracer, for characterizing aquifers, flow conditions, and crucial transport processes, such as mechanical dispersion.
• Determine the fate and evolution of pollutants and micropollutants introduced in natural systems by the leakage from sewers and the discharge of wastewaters.
• Explain the influence of urbanized areas and sealed surfaces in the aquifer behavior.
• Improve predictions concerning groundwater extraction, injection and/or both, and their associated impacts.
• Understand the consequences and risks associated with CO2 storage.
• Identify and quantify aspects that may impact the urban groundwater and investigate methods for minimizing their influence (e.g., artificial groundwater recharge, improvement of the “natural” recharge in urban areas, reuse of pumped groundwater, redesign of geothermal systems, etc.) and to enhance groundwater management strategies.
This session welcomes contributions that deliver new insight in the field of hydraulic, thermal, chemical and mechanical processes in saturated media, specially, but not restricted to, in urban aquifers, including experimental design, reports from new field observations, demonstration of sequential or coupled physical and numerical modelling concepts or case studies.

EMRP1.2

Geophysical methods have a great potential for characterizing subsurface properties and couple THM processes to inform geological, reservoir, hydrological, and (bio)geochemical studies. In these contexts, the classically used geophysical tools only provide indirect information about subsurface heterogeneities, reservoir rocks characteristics, thermo-hydro-mechanical coupling, and associated processes (e.g. flow, transport, bio-geochemical reactions). Rock physics relationships hence have to be developed to provide links between physical properties (e.g. electrical conductivity, seismic velocity or attenuation) and the intrinsic parameters of interest (e.g. fluid content, hydraulic properties, coupled processes). In addition, geophysical methods are increasingly deployed as time-lapse, or even continuous, and distributed monitoring tools on more and more complex environments. Here again, there is a great need for accurate and efficient physical relationships such that geophysical data can be correctly interpreted (e.g. included in fully coupled inversions). Establishing such models requires multidisciplinary approaches since involved theoretical frameworks differ. Each physical property has its intrinsic dependence to pore-scale interfacial, geometrical, and (bio)geochemical properties or to external condition (such as pressure or temperature). Each associated geophysical method has its specific investigation depth and spatial resolution which adds a significant level of complexity in combining and scaling theoretical developments with laboratory studies/validations and/or with field experiments. This session consequently invites contributions from various communities to share their models, their experiments, or their field tests and data in order to discuss about multidisciplinary ways to improve our knowledge on reservoir and near surface environment.

ERE7 – Nexus approaches and applications

ITS1.1/ERE7.1

The world's energy, water, and land systems are in transition and rapidly integrating, driven by forces such as socioeconomic, demographic, climatic, and technological changes as well as policies intended to meet Sustainable Development Goals (SDGs) and other societal priorities. These dynamics weave across spatial scales, connecting global markets and trends to regional and sub-regional economies. At the same time, resources are often locally managed under varying administrative jurisdictions closely tied to inherent characteristics of each commodity such as river basins for water, grid regions for electricity and land-use boundaries for agriculture. Local decisions in turn are critical in deciding the aggregate success and consequences of national and global policies. Thus, there is a growing need to better characterize the energy-water-land nexus to guide robust and consistent decision making across these scales. This session invites abstracts exploring energy-water-land dynamics, trade patterns, policy interventions, infrastructure planning and uncertainty characterization across variable spatial boundaries.

ITS1.12/BG1.20

A grand challenge facing society in the coming decades is to feed the growing human population in a sustainable and healthy manner. This problem is made more complex by an increasingly globalised food system and its interactions with a changing climate. Agri-food system actors - including policy makers, corporations, farmers, and consumers - must meet this challenge while considering potentially conflicting priorities, such as environmental sustainability (e.g., minimising disturbance to ecosystems via greenhouse gas emissions and the use of water, land, fertilisers and other inputs), economic viability (e.g., revenues for food producers and guaranteed access for consumers), nutritional balance and quality (e.g., addressing overconsumption and undernourishment), and resilience to climate change.
This growing complexity of agri-food systems, which can involve global supply chains and difficult environmental and societal tradeoffs, needs to be better understood.
The type of product (e.g. plant or meat based, fresh or processed), as well as the location and method of production, can play an important role in improving the nutritional quality and environmental sustainability of global food production, to enable healthy and sustainable diets. Quantifying and assessing these multiple outcomes while accounting for the linkages, interconnections, and scales of local and global supply chains will be essential for informing decisions aimed at developing sustainable and resilient agri-food systems.
This session welcomes submissions that quantify and assess a range of outcomes from agri-food systems across multiple spatial and temporal scales, and the trade-offs or synergies between them. The session will include studies providing improved methods for quantifying multiple environmental, economic or social dimensions, studies that incorporate the role of food trade into solution-development, and studies that seek to achieve multiple sustainability goals together.

HS7.3

Hydroclimatic conditions and the availability of water resources in space and time constitute important factors for maintaining an adequate food supply, the quality of the environment, and the welfare of inhabitants, in the context of sustainable growth and economic development. This session is designed to explore the impacts of hydroclimatic variability, climate change, and the temporal and spatial availability of water resources on: food production, population health, the quality of the environment, and the welfare of local ecosystems. We particularly welcome submissions on the following topics:

Complex inter-linkages between hydroclimatic conditions, food production, and population health, including: extreme weather events, surface and subsurface water resources, surface temperatures, and their impacts on food security, livelihoods, and water- and food-borne illnesses in urban and rural environments.

Quantitative assessment of surface-water and groundwater resources, and their contribution to agricultural system and ecosystem statuses.

Spatiotemporal modeling of the availability of water resources, flooding, droughts, and climate change, in the context of water quality and usage for food production, agricultural irrigation, and health impacts over a wide range of spatiotemporal scales

Intelligent infrastructure for water usage, irrigation, environmental and ecological health monitoring, such as development of advanced sensors, remote sensing, data collection, and associated modeling approaches.

Modelling tools for organizing integrated solutions for water, precision agriculture, ecosystem health monitoring, and characterization of environmental conditions.

Water re-allocation and treatment for agricultural, environmental, and health related purposes.

Impact assessment of water-related natural disasters, and anthropogenic forcings (e.g. inappropriate agricultural practices, and land usage) on the natural environment; e.g. health impacts from water and air, fragmentation of habitats, etc.

ITS2.10/NP3.3

Last year sessions ITS6.1-3 on urban geosciences have largely confirmed the urgency to develop inter-/trans-disciplinary approaches of urban geosciences to respond to the huge societal demand to radically improve urban systems and their interactions with their environment and climate. The session ITS.6.1 focussed on the need to develop holistic approaches going beyond specialised domains such as urban meteorology, hydrology, climatology, ecology and resilience to grasp the urban-geophysical systems in their multi-component and multiscale complexity. This in particular indispensable to resolve long lasting questions like multi-hazard threats and upscaling of climate solutions. The recent IPCC report 1.5°C confirms the necessity to fully take into account the multi-component complexity of the urban-geophysical systems to achieve the urban and infrastructure transition, one of the main four system transitions to be achieved

The present session calls therefore for contributions on the development transdisciplinary concepts, methodologies and tools, as well as their applications to urban-geophysical systems in view of this transition. Jean Jouzel (former IPCC vice-president) will open this session.
