The 2026 France Habe Prize

This year, although the topics addressed by the candidates were very diverse, they were approached through a wide range of options, such as the protection and conservation of caves and karst environments, raising awareness of caving, the interplay between exploration findings and scientific research, education and tourism, whilst also identifying ways to ensure the long-term sustainability of their objectives.

The members of the jury for the 2026 France Habe Prize assessed each submission using an evaluation grid that focused on relevance, presentation, interdisciplinarity, photography, scientific content, readability, and originality.

They unanimously decided to award the 2025 France Habe Prize to the project entitled “Photographic, topographical and digital documentation of the deep sections of the Aven d’Orgnac” (France), submitted by Rémi FLAMENT.

The winner receives a cash prize of €300 awarded by the UIS, as well as caving equipment donated by the firms BARHAR ($250) and RESSEG (€300).

Details of the project will be presented by the winner in the next UIS Bulletin.

The Jury congratulates the other participants on their enthusiasm for caving and their commitment to the protection of caves and karst.

Origin of the prize

The France HABE Prize has been awarded since 2013 by the Commission for the Protection of Karst and Caves of the International Union of Speleology (UIS).
The aim of this award is to promote the protection of karst and caves for future generations. This natural heritage is a proven source of increasingly rich information about the history of our planet and humanity, enabling people to act in a more thoughtful, effective, and sustainable manner for the future of our environment.

The prize is named in memory and honor of Dr France HABE († 10 December 1999) from Slovenia (Yugoslavia), who, amongst her many roles and achievements, served as Chair of the UIS Protection Department from 1973 to 1997.

Subterranean Myths

The 1st International Arts & Letters Contest | 2026

This contest is a creative call to all cavers, speleologists, and karst explorers at heart who see the underground world not only as a place of exploration but as a source of artistic inspiration. Whether you are a scientist documenting the depths or an explorer shaped by the silence of the cave, we invite you to share your unique perspective.

Theme: “Subterranean Myths” – Artistic Reflections of the Karst World

Tagline: Below the Surface, Beyond Imagination

The Arts and Letters Committee is proud to announce its first international call for entries. This contest is an invitation to explore the world beneath our feet through the lens of creativity.

Concept: What are “Subterranean Myths”?

This theme goes beyond ancient folklore. We invite you to reflect on the deep human connection to the underground environment, blending scientific reality with poetic intuition.

This includes:

• Geological Time & Silence: Reflecting on the profound stillness and absolute darkness of the deep.
• Nature’s Artistry: Geochemical processes and karst structures (stalactites, crystals) as living sculptures.
• Psychological Journeys: Reflections of fear, discovery, and the thrill of adventure in the depths.
• Subterranean Echoes: The haunting dialogue between sound, void, and the “breath” of the cave.
• Ancestral Memory: The stories stored within rock layers and the living memory of the stone.
• The Cave as a Metaphor: A portal to the subconscious or a sanctuary for the “unseen” self.
• Liquid Architecture: The slow, poetic dance of water and minerals sculpting time itself.
• Modern Myths: New legends born at the intersection of scientific exploration and creative imagination.

Categories & Constraints:

• Visual Arts: Painting, drawing, digital art, and illustration. (Note: Photography and photomontage are not accepted in this category).
• Writing: Poetry, short stories, essays, and literary articles (Max. 1,000 words).

Dear colleagues, dear friends,

We are glad to inform you that the first Call for speleological events support in 2026 is open! Granted can be international expeditions or other events focused on the exploration, study, or protection of caves and karst, with an emphasis on educational, technical, and/or scientific cooperation.

UIS Bureau especially encourages young cavers and scientists to submit proposals for their projects, and the Bureau will take these submissions into preference consideration.

All requests should contain a description of the proposed event as detailed as you think is important for understanding the aims of your project, the purpose for which the funds will be used, and show explicitly that the proposed event is in line with the Statutes, Internal Regulations, and Code of Ethics of the UIS. Requests that do not meet these requirements will not be accepted.

For speleological expeditions, participants must be from at least 3 different countries, one of which is recommended to be the host country where the project will be conducted.

Detailed conditions and more details about speleological events support can be found in Speleological Events Support Guidelines on https://uis-speleo.org/wp-

The deadline for this Call is June 12, 2026.

All requests received till the deadline will be evaluated by the UIS Bureau, and the best projects will be supported. For this Call, the UIS Bureau decided to dedicate a maximum amount of 3000 EUR, meaning that this total amount can be split between all supported projects. All requests received after the deadline will not be accepted, but can be submitted for the next call.

Unlike what is reported in the Speleological Event Support Guidelines, please send all requests to the UIS before the deadline to Adjunct Secretary Marc Mentens at marcbingcacao@gmail.com and Adjunct Secretary Allan Calux at ascalux@gmail.com (in CC).

Before submitting, please ensure that:
