1. The Society (iEMSs) is a not-for-profit organization uniting private persons and organizations dealing with environmental modelling, software and related topics.

2. The aims of the iEMSs are to:

  • develop and use environmental modelling and software tools to advance the science and improve decision making with respect to resource and environmental issues. This places an emphasis on interdisciplinarity and the development of generic frameworks and methodologies which integrate models and software tools across issues, scales, disciplines and stakeholders with respect to resource and environmental issues;
  • promote contacts among physical, social and natural scientists, economists and software developers from different countries and coordinate their activities;
  • improve the cooperation between the sciences and decision makers/advisors on environmental matters;
  • promote environmental modelling and software;
  • exchange information in the field of environmental modelling and software among scientific and educational organizations and private enterprises, as well as non-governmental organizations and governmental bodies.

3. To achieve these aims, the iEMSs:

  • organizes international conferences, meetings and courses in environmental modelling and software;
  • publishes scientific studies and popular scientific materials in the Environmental Modelling and Software journal (Elsevier);
  • hosts a website which allows members to communicate research and other information relevant to the Society’s aims with one another and the broader community;
  • delivers a regular newsletter to members.

New book: Monitoring, Simulation, and Management of Visitor Landscapes

Conventional methods used in the planning and management of human-landscape interactions fall far short of the needs of today’s land management professionals. The book Monitoring, Simulation, and Management of Visitor Landscapes, edited by Randy Gimblett and Hans Skov-Petersen, published by University of Arizona Press, presents a growing body of applied research that provides decision makers with tools to maintain the ecological integrity of public places by evaluating the impacts of humans in various landscapes across space and time. More information available on the book website.

New Book Series: Developments in Integrated Environmental Assessment

The IDEA book series addresses the increasing importance for interdisciplinary systems research that relates to assessing policy and resource management options that could lead to improved sustainability outcomes. It aims to capture current trends in, and promote the advancement of: new intellectual tools and processes that integrate consideration of multiple issues, interest groups, disciplines and scales in addressing the wide-ranging impacts of controllable and uncontrollable drivers on socioeconomic, ecological, hydrological and institutional performance.
