Several types of nature-based solutions (NbS) for land and water management have been implemented. They are multi-beneficial, not only to prevent and mitigate climate-related risks, providing more resilient cities, but also to improve human well-being and further pave the way towards a more resource efficient, competitive and greener economy. However, adequate proof-of-concept for economic, social and environmental benefits provided by NbS is needed to promote their inclusion in planning and decision-making processes.
This session aims to promote exchange of knowledge regarding NbS and to discuss their relevance for sustainable development, through evidence-based and scalable case studies. The session seeks to:
• Better understand advantages and disadvantages of NbS, based on field applications;
• Provide new insights and perspectives of NbS at catchment level, particularly their role on water, sediment, nutrient and pollutant fluxes;
• Introduce new methods and tools to investigate the role of NbS in the context of climate change, namely its effectiveness for mitigation and/or adaptation to it;
• Identify opportunities and barriers driven by current regulatory frameworks and management practices, and how the former can be reaped and the latter overcome, for successful implementation of NbS;
• Present an overview of case studies and examples of NbS projects that could involve the private sector and market-based mechanisms;
• Discuss the interactions between NbS and the Sustainable Development Goals (SDGs).

The soil environment hosts a vast array of interfaces, ranging from those between microbes and aggregates, bulk soils and roots, to the interactions of soils with the bedrock and atmosphere. A range of physical, biological and chemical processes occur at these interfaces across different spatial and temporal scales, sustaining a wealth of ecosystem functions and services.

Soil systems are therefore dynamic environments. The behaviour and response of these complex systems to short-term perturbation and long-term environmental change pose fascinating challenges for soil scientists. Many of the major drivers of environmental change are anthropic in origin, including accelerated climatic change and shifts in land use and management. To ensure soils continue to provide valuable functions and services it is vitally important that we study the wide variety of soil interfaces and understand how the processes occurring across them may respond to current and potential future environmental change scenarios.

In this session we hope to bring together researchers at all career stages from different sub-disciplines of soil science to discuss these interactions and how these are affected by broader changes within the environment. Soil systems encompass an exceptional array of biogeochemical components; as such we welcome studies from a wide range of researchers using empirical or modelling-based approaches. We especially encourage contributions which present research encompassing different components of the soil system and the interactions between soil processes and the wider environment.

Acid sulfate soils are found around the world in both coastal and freshwater environments. These soils are dominated by metal sulfides, which, when exposed to oxygen, oxidise and result in acidification of soil and water. Acidification causes detrimental impacts to agricultural land, natural and managed ecosystems and infrastructure in urban environments. We invite submissions on all aspects of acid sulfate soils, sulfidic materials, and wetland soils in natural, managed and anthropogenic ecosystems.

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented in collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, a special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring high natural risk areas, such as: volcanic, seismic, slope instability and other environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, seismology, geodesy, geochemistry, remote sensing, volcanology, geotechnical and soil science. In this context, the contributions in analytical and numerical modeling of geodynamics processes are also welcome.
Finally, a special reference is devoted to the integration through the use of GeoWeb platforms and the management of visualization and analysis of multiparametric databases acquired by different sources
