Environmental Modelling & Software – New Impact Factor

According to the latest Clarivate report, our journal Environmental Modelling & Software (ENSO) has achieved another increase in its impact factor, up to 5.471 in 2021 (from 5.288 in 2020). In addition, the SCOPUS/Elsevier-associated CiteScore for 2021 is 9.5 (up from 9.4 in 2020). This ongoing success would not be possible without all editors, reviewers and of course all iEMSs members and friends submitting state-of-the-art manuscripts and supporting the review process.

SESYNC Webinar ‘Modeling Behavioral Change in Socio-Environmental Systems’ June 20, 2022


Expanding the development and use of socio-environmental system (SES) models is critical to solving urgent problems situated at the human-nature interface. Substantial progress is being made, but modeling challenges associated with a range of diverse issues remain. This is the fifth in a series of webcasts based on the 2020 article “Eight grand challenges in socio-environmental systems modelling” by Sondoss Elsawah and colleagues.

This webcast and panel discussion event is focused on the critical challenge of incorporating the human dimension in SES modeling. The webcast will present the state of the art in modeling behavioral change, fundamental scientific challenges, and promising research directions. The event is intended for practitioners and scholars who commission, sponsor, or use SES models. It will begin with a pre-recorded presentation by Dr. Jonathan Gilligan, followed by a short talk from each panelist reflecting on the specific challenges and solutions for incorporating human dimension using case studies from their experience. Then an open discussion will follow. Viewers may post questions and comments.

iEMSs Statement on the war in Ukraine

The International Environmental Modelling & Software Society, on behalf of its members, strongly condemns the attack on Ukraine and expresses its support for our Ukrainian colleagues. This violent invasion of a sovereign country is an attack on the fundamental values of democracy and freedom, on which academic freedom and academic cooperation are based. We stand in solidarity with everyone who opposes war and armed conflict, anywhere, at any time. In particular, we stand with those bravely defending their homes and families in Ukraine, and those who defy the Russian government’s bans, protesting and openly opposing the war.

Stefan Reis, President iEMSs
