ANDEX is a Regional Hydroclimatic Program for the Andes. The program is part of the GEWEX Hydroclimatology Panel (GHP) of the Global Energy and Water Exchanges Program (GEWEX), one of the core projects of the World Climate Research Program (WCRP). One key goal of ANDEX is to become a regional hydroclimatic program of reference constituted by a consolidated and articulated scientific community that responds to the needs of society and contributes to planning and decision-making for the sustainable development of the Andean countries. Water security for Andean populations, and high-impact hydroclimatic events, constitute our two main themes of research, production and dissemination of knowledge and information.
The ANDEX Annual Meetings represent one core activity of the program, and this year this event will take place at the facilities of CCT CONICET Mendoza, Argentina, between October 13 and 18, 2025. The aim is to bring together the members of the ANDEX community as well as collaborators working on the different Andean countries. Also anticipated, is a vibrant participation of members of JovenANDEX, a network created to incorporate the vision, needs and activities of early career scientists within the ANDEX program.
It is important to note that the ANDEX activities in Mendoza in 2025 are being organized in the context of the International Year of Glacier’s Preservation, a joint worldwide initiative recently launched by WMO and UNESCO.
This year’s annual meeting will include:
During the event, a series of introductory one-day workshops will be organized and led by ANDEX members who are leaders in that particular scientific field and include the following topics:
At the end of the meeting there will be an optional field trip to the upper Mendoza River basin that will conclude with a magnificent view of Cerro Aconcagua (6962 m), the highest mountain in the world outside the Tibetan Plateau in Asia. The final agenda for the meeting will be available in the August 2025. The preliminary agenda can be accessed at https://www.gewexevents.org/meetings/2025andex/agenda/.
The 2025 ANDEX annual meeting is open to ANDEX colleagues and collaborators from the Andean countries (or elsewhere) whose research activities focus on water issues and/or high-impact hydroclimatic events in the Andes cordillera.
There is no registration fee for the event and a limited amount for travel support is available. Note that the travel support will be largely used to cover the participation of early career scientists from the Andean countries. We encourage all interested participants to seek their own funding to cover travel, meals and accommodation in Mendoza, Argentina.
Please register no later than July 1st, 2025 at https://www.gewexevents.org/meetings/2025andex/registration/.
If you are requesting travel support, please register as soon as possible, at the latest by June 10th, 2025. No travel support applications will be considered after this date.

All attendees and participants are expected to conduct themselves with integrity and in a manner that is professional, respectful, tolerant and responsible. A zero-tolerance approach will be applied to any form of discrimination or harassment, including but not limited to sexual harassment and bullying.
Discrimination is any unfair treatment or arbitrary distinction based on a person’s race, religion, nationality, ethnic origin, sexual orientation, disability, age, language, social origin or other status. Discrimination may be an isolated event affecting one person or a group of persons similarly situated or may manifest itself through harassment or abuse of authority.
Harassment is any improper and unwelcome conduct that might reasonably be expected or be perceived to cause offense or humiliation to another person because of inter alia, an individual’s gender, gender identity and expression, sexual orientation, disability, physical appearance, ethnicity, national origin, age, or religion. Bullying is unwelcome, aggressive behavior involving the use of influence, threat, intimidation, or coercion to dominate others in the professional environment.’
Harassment or bullying may take the form of words, gestures or actions which tend to annoy, alarm, abuse, demean, intimidate, belittle, humiliate or embarrass another or which create intimidating, hostile or offensive professional environment.
Sexual harassment is a specific type of prohibited conduct. It is any unwelcome conduct of a sexual nature. Sexual harassment may be any conduct of a verbal, including via electronic or telephonic means, nonverbal or physical in nature and may occur between persons of the opposite or same sex.
In the event that a participant of this conference, feels that an issue has arisen regarding disrespectful treatment, harassment bullying or discrimination, regardless of whether it rises to the level of breach of this conduct, the member or event participant is encouraged to discuss it in confidence, with anyone in the list below, as appropriate:
or send a message to contact@gewexevents.org with your contact information and a short description of the issue.
In the event of a clear or perceived breach of the code of conduct, it may be reported in writing to the Director of the International GEWEX Project Office, or the Chair(s) of the GEWEX SSG. Once this is received, a GEWEX SSG member will be appointed as point of contact, who will first discuss with the complainant on how they wish to proceed.
All reports and allegations of breaches to this code of conduct will be handled sensitively and in confidence. The immediate priority will be to protect the privacy of the person(s) exposed to the breach of conduct and the need for further action will be assessed carefully on a case-by-case basis.
The organizers cannot accept liability for personal accident, loss, or damage to private property, which may be incurred as a result of participation in the 2nd LIAISE Conference. Participants are, therefore, advised to arrange appropriate insurance coverage.
The organizing committee will not accept liability for damages of any nature sustained by participants or loss of or damage to their personal property as a result of any event.
The agenda will become available at second half of April 2025.
