Call for papers

The Spanish-Portuguese Association of Natural and Environmental Resources Economics is glad to announce that its IX AERNA Conference will be a hybrid meeting.

Participants will be able to choose between making their presentations in-person in the conference room or online through an online platform.

The conference will take place, as announced, at the University of Lleida on the 2nd and 3rd of September, 2021. 

We are keeping our initial plans of celebrating an in-person conference, but due to the impossibility of knowing the evolution of the COVID19 pandemic we have decided to offer the possibility of a hybrid conference.

The call for papers is now open and submissions on all relevant topics related to Environmental and Natural Resource Economics are invited.  You do not need to commit either to an in person or to a virtual presentation at the time of submission. Once the acceptation process have ended, we will ask for your presentation-preferred mode. We understand that traveling under the current circumstances could be very large burden. In the case that the evolution of the pandemic would not allow the celebration of the in person conference all the presentations will be on line.

The registration fees for online participation are going to be different from the in person participation.  We are now working on these details and we will let you know about them later on.

We encourage to submit papers written in English. Submissions in Spanish and in Portuguese will also be possible, however, these presentations will be pool together in special sessions.  Submitted contributions are expected to be work in progress at a reasonably advanced stage but still unpublished. Only .pdf files will be accepted. Young researchers and PhD students who wish to attend are most welcome. All submissions will undergo the regular peer review process. Notification of submission acceptance is expected by April 11th, 2021.

AERNA Best Paper Award for an Economist under the Age of Forty

During the Conference, AERNA is granting its AERNA Best Paper Award for an Economist under the Age of Forty, a recognition given to the best paper presented by a young economist at the AERNA’s Annual Conference. The Award aims to reward new ideas addressing key environmental and resource economic issues at the national, European, and global scale. Both theoretical and empirical papers will be considered without any restriction on topics. Priority will be given to papers by a single author or multiple authors complying with the age requirement. There is a monetary reward of €500 for the presenter of the winning paper. The Selection Committee is formed by a person appointed by AERNA Council, acting as a chair, and two persons appointed by the Chairs of the Programme Committee. All eligible presenters can submit their candidacy to the Award at the paper submission process.
