This book constitutes the refereed proceedings of the 13th IFIP WG 5.11 International Symposium on Environmental Software Systems, ISESS 2020, held in Wageningen, The Netherlands, in February 2020. The 22 full papers and 3 short papers were carefully reviewed and selected from 29 submissions. The papers cover a wide range of topics on environmental informatics, including data mining, artificial intelligence, high performance and cloud computing, visualization and smart sensing for environmental, earth, agricultural and food applications.

This book constitutes the refereed proceedings of the 9th IFIP WG 5.11 International Symposium on Environmental Software Systems, ISESS 2011, held in Brno, Czech Republic, in June 2011. The 68 revised full papers presented together with four invited talks were carefully reviewed and selected from numerous submissions. The papers are organized in the following topical sections: eEnvironment and cross-border services in digital agenda for Europe; environmental information systems and services - infrastructures and platforms; semantics and environment; information tools for global environmental assessment; climate services and environmental tools for urban planning and climate change - applications and services.

Environmental Informatics is a fast growing field which deals with all methods from computer science, environmental planning, ecology and related subjects. As well as being an interdisciplinary area, Environmental Informatics provides an interface between all involved professional groups. Monitoring the state of the environment, analysing existing data, presenting the data to scientists and the public, as well as providing decision support are only some of the topics involved. Environmental Informatics is therefore a good foundation for the computer-assisted protection of the environment.

Environmental Informatics (or Enviromatics) is a maturing subject with interdisciplinary roots in computer science, environmental planning, ecology, economics and other related areas. Its practitioners must be prepared to work with many diverse professional groups. It forms the foundation for computer-assisted environmental protection. This book contains an edited version of papers presented at the 3rd International Symposium on Environmental Software Systems (ISESS '99), which was held at the University of Otago, Dunedin, New Zealand, from August 30 to September 2, 1999, and was sponsored by the International Federation for Information Processing (IFIP). The text is divided into six sections: * Enviromatics - Introduction; * Environmental Issues; * Environmental Information Systems - Tools and Techniques; * Environmental Information Systems - Implementations; * Environmental Decision Support Systems; * Specialised Topics. This state-of-the-art volume will be essential reading for computer scientists and engineers, ecologists, and environmental planners and managers.

Due to increasing practical needs, software support of environmental protection and research tasks is growing in importance and scope. Software systems help to monitor basic data, to maintain and process relevant environmental information, to analyze gathered information and to carry out decision processes, which often have to take into account complex alternatives with various side effects. Therefore software is an important tool for the environmental domain. When the first software systems in the environmental domain grew - 10 to 15 years ag- users and developers were not really aware of the complexity these systems are carrying with themselves: complexity with respect to entities, tasks and procedures. I guess nobody may have figured out at that time that the environmental domain would ask for solutions which information science would not be able to provide and - in several cases - can not provide until today. Therefore environmental informatics - as we call it today - is also an important domain of computer science itself, because practical solutions need to deal with very complex, interdisciplinary, distributed, integrated, sometimes badly defined, user-centered decision processes. I doubt somebody will state that we are already capable of building such integrated systems for end users for reasonable cost on a broad range. The development of the first scientific community for environmental informatics started around 1985 in Germany, becoming a technical committee and working group of the German Computer Society in 1987.

This book constitutes the refereed proceedings of the 12th IFIP WG 5.11 International Symposium on Environmental Software Systems, ISESS 2017, held in Zadar, Croatia, in May 2017. The 35 revised full papers presented together with 4 keynote lectures were carefully reviewed and selected from 46 submissions. The papers deal with environmental challenges and try to provide solutions using forward-looking and leading-edge IT technology. They are organized in the following topical sections: air and climate; water and hydrosphere; health and biosphere; risk and disaster management; information systems; and modelling, visualization and decision support.
