Citizen science (the involvement of the public in scientific processes) is gaining momentum in one discipline after another, thereby more and more data on biodiversity, earthquakes, weather, climate, health issues among others are being collected at different scales that can extend the frontiers of knowledge. Successful citizen observatories can potentially be scaled up in order to contribute to larger environmental and policy strategies and actions (such as the European Earth Observation monitoring systems) and to be integrated in GEOSS and Copernicus. Making credible contributions to science can empower citizens to actively participate in environmental decision making, can raise awareness about environmental issues and can help bridge the science-society gap. Often, citizen science is seen in the context of Open Science, which is a broad movement embracing Open Data, Open Access, Open Educational Resources, Open Source, Open Methodology, and Open Peer Review to transparently publish and share scientific research - thus leveraging Citizen Science and Reproducible Research.

Both, open science in general and citizen science in particular, pose great challenges for researchers, and to support the goals of the various openness initiatives, this session looks at what is possible nowadays and what is ready for application in geosciences. Success stories, failures, best practices and solutions will be presented, in addition to various related networks. We aim to show how researchers, citizens, funding agencies, governments and other stakeholders can benefit from citizen science and open science, acknowledging the drawbacks and highlighting the opportunities available for geoscientists.

In this session, we are looking for successful approaches of working with citizen science and open science to bridge the gap between a multitude of stakeholders in research, policy, economy, practice and society at large by finding emerging environmental issues and empowering citizens. This session shall be an open space to exchange experiences and to present either successful examples or failed efforts. Learning from others and understanding what to adopt and what to change help the participants in their own undertakings and new initiatives, so that they become future success stories.

We want to ask and find answers to the following questions:
Which approaches can be used in Earth, Planetary and Space Sciences?
What are the biggest challenges and how to overcome them?
What kind of citizen scientist involvement and open science strategies exist?
How to ensure transparency in project results and analyses?
How to evaluate successful bridging of the science-society-gap?

Natural hazards and the associated risk are in some cases a major hindrance to economic and social growth in economically developing countries. This is particularly evident for urban areas, since rapid and uncontrolled urbanization in hazard-prone regions may result in a significant increase in risk due to insufficient spatial planning, which sometimes does not correctly consider (if at all) the impact of natural hazards, and to inadequate building practices. This session will profile the challenges faced in the developing world when doing assessments of natural hazard and risk and designing mitigation strategies. Examples of these challenges include (i) a frequent lack of data, along with difficulties in collecting it, (ii) rapid and often unplanned urban development, with building practices often neglecting the potential hazards, (iii) less regulated nature-human interactions, (iv) limited resources and capacity to undertake the most appropriate prevention and mitigation actions and to actually respond to disastrous and extreme events, (v) climate change, and (vi) difficulties in communication between science, policy and decision makers, and the general public.
Submissions to this PICO session covering all relevant topics are welcome, including but not limited to: database and archive construction; modeling, monitoring and tools for natural hazard and risk assessment; conceptual understanding of multi-hazards and nature-technology interactions; response and mitigation strategies; and communications, policy and decision-making. We particularly welcome abstracts focusing on urban areas, as well as the participation of stakeholders to share their innovative theoretical and practical ideas and success stories of how risk can be understood and addressed across economically developing countries.

The Sustainable Development Goals (SDGs) (or Global Goals for Sustainable Development) are a collection of 17 global goals set by the United Nations Development Programme.The formal name for the SDGs is: "Transforming our World: the 2030 Agenda for Sustainable Development." That has been shortened to "2030 Agenda." The goals are broad and interdependent, yet each has a separate list of targets to achieve. Achieving all 169 targets would signal accomplishing all 17 goals. The SDGs cover social and economic development issues including poverty, hunger, health, education, global warming, gender equality, water, sanitation, energy, urbanization, environment and social justice.
For this interdisciplinary session, we invite contributions discussing How Earth, Planetary and Space Scientists can address UN Sustainable Development Goals . We shall discuss the relevance of fields of research disciplines covered by EGU, and how they can inform and support society government bodies, and stakeholders for the SDGs.
The session will include invited and contributed oral papers, as well as interactive posters, and panel discussions.

Over the past decades, many initiatives have been produced to archive the losses and datasets associated with natural perils events (EM-DAT, MunichRe NATCATservice, SwissRe Sigma, CATDAT, Dartmouth Flood Observatory etc.). On a European scale, much research has also been undertaken on a Europe-wide, country and subcountry level either using Desinventar or through other academic and insurer data archiving. However, these loss databases provide varying levels of parameters, data completeness, quality checks, spatial integration, and spatiotemporal limits. In addition, the types of data collection and definitions of loss often differ greatly between databases.

With over 3000 Open Data Initiatives around Europe (www.europeandataportal.eu/) and the World, the amount of data freely available is increasing, but censoring and data checks are required in order to ensure that the quality is reasonable. This similarly goes for online media archives and loss reporting. Even though some initial attempts have been made to connect different databases and stimulate consistency and open access (e.g. IRDR-DATA), this is a topic that needs to be explored further.

This session aims to advance efforts on loss data collection and provide a future inventory of socioeconomic loss databases for loss and risk analysis as well as to create a community linking academia, government and insurance.

Abstracts are welcomed in the following fields:-
- Socioeconomic loss databases for natural perils
- Infrastructure and sectoral loss archiving
- Online media initiatives for collecting loss data (e.g. twitter)
- Post-disaster loss analysis
- Online analysis of loss data or loss reporting
- Parametric risk transfer products
- GIS integration of past natural hazards event data
- Open data efforts for loss modelling
- Insurance loss data and loss archives
- Government post-disaster loss analysis and loss databases
- Other relevant loss-related research

Climate services challenge the traditional interface between users and providers of climate information as it requires the establishment of a dialogue between subjects, who often have limited knowledge of each-other’s activities and practices. Increasing the understanding and usability of climate information for societal use has become a major challenge where economic growth, and social development crucially depends on adaptation to climate variability and change.

To this regard, climate services do not only create user-relevant climate information, but also stimulate the need to quantify vulnerabilities and come up with appropriate adaptation solutions that can be applied in practice.

The operational generation, management and delivery of climate services poses a number of new challenges to the traditional way of accessing and distributing climate data. With a growing private sector playing the role of service provider is important to understand what are the roles and the responsibilities of the publicly funded provision of climate data and information and services.

This session aims to gather best practices and lessons learnt, for how climate services can successfully facilitate adaptation to climate variability and change by providing climate information that is tailored to the real user need.
Contributions are strongly encouraged from international efforts (GFCS, CSP, ClimatEurope…); European Initiatives (H2020, ERA4CS, C3S, JPI-Climate…) as well as national, regional and local experiences.

In spring and summer 2018, Central and Northern Europe faced a severe drought with rainfall deficits beginning as early as April and lasting until late August in some regions (partly combined with a heat wave in July and August). Due to higher spring temperatures and high radiation the Baltic Sea showed a very unusal low pCO2 signal since late April and a spectacular summer bloom this year. The impact on terrestrial ecosystems became obvious through crop failure and forest fires. This transdiciplinary session calls for scientific results from Earth Observation showing the impact of the drought and for presentations from the interface between science a climate action e.g. adaptation strategies, questions on measuring, reporting and verification of inventories or general communication of climate change to societies.

Geodiversity is an interest for all geosciences, where the natural environment for our science is recorded and assessed. Geoheritage is the appreciation, valuation, and sustainable exploitation of part of this geodiversity for the good of the environment, for society and for science. Geodiversity and geoheritage provide essential links to other disciplines in the natural and social sciences, and they give geosciences a voice to the greater public and to local to global governance.
The EGU geodiversity and geoheritage session has been a large and vibrant meeting spot for a large diverse assemblage of geoscientists and stakeholders for over 5 years, growing with the increasing appreciation of the central role these topics have.
This EGU 2019 session aims to highlight the hottest issues and challenges pending or emerging, as well as inviting a broad range of topics, to engage in a far reaching discussion. As in previous years, we will hold a Splinter Meeting to further discuss hot topics, and will animate the poster session with a special picnic session.

Five main themes to tackle have been identified for 2019:

1) Society, climate change and geodiversity: the problems related to economic and environmental dynamics affecting geodiversity under changing climate and global development conditions. This topic has implications for and links to the IUGS RFG (Resourcing Future Generations) initiative and is a central theme for UNESCO Global Geoparks and World Heritage, and concerns also the management of all types of natural risk.

2) Geo- to ecosystem services and geoheritage: this follows from the first theme in exploring the possibility of developing a holistic and integrated approach to geodiversity, by considering geosystem services, in a perspective of sustainable management of geoheritage to the benefit of the whole environment.

3) Geodiversity, geosites and geoheritage assessments at multiple spatial scales: integrating data from global to local: the present lack of integration between global, regional and local geological and geomorphological data can limit the validity of geodiversity assessment and prevent its applicability for enhancement and protection of geoheritage. This subject relates to practical issues on different spatial scales for geodiversity immediately applicable to the protection of geodiversity, geoheritage and has links with the problems raised in the first two themes.

4) Virtual and Augmented Reality and Geoheritage: the strong innovation potential for this research field due to enhanced application of geoinformation technologies (GIS and Semantic Web). This use of global platforms, such as Google Earth, to outcrops scale augmented reality is a powerful research and educational tool that is developing fast. This theme will draw together demonstrations of the ongoing development of such techniques and their practical implementation into geodiversity and geoheritage sites.

5) Towards a fruitful integration/collaboration of international designations; this is a topic that we invite discussion about, and which is being hotly discussed between the major geoscience unions, associations, programmes and global instances like the UNESCO’s International Geoscience and Geoparks Programme and Convention Concerning the Protection of the World Cultural and Natural Heritage, the IUGS International Geoheritage Commission and the International Union for the Conservation of Nature, especially through the Geoheritage Specialist Group/WCPA. It will form a subject of the Splinter Meeting, where these major unions will be open to discuss the theme.

Geodiversity and Geoheritage attract a broad range of people from all sides of geosciences and therefore we invite all this diversity to participate in the session.

The session is co-sponsored by the Working Group on Geomorphosites and the Working Group on Landform Assessment for Geodiversity of the International Association of Geomorphologists; ProGEO, the European Association for the Conservation of the Geological Heritage; the IUGS International Commission on Geoheritage; the Geoheritage Specialist Group of the World Commission on Protected Areas of the International Union of Conservation of Nature, the International Lithosphere Program, and the IAVCEI Commission on Volcanic Geoheritage and Protected Volcanic Landscape.
The session is closely linked to the those of Geoheritage Stones, and to Volcano Resources.
