UNESCO

Chair on Heritage Futures

Preparing MONDIACULT 2025

2024-11-22

On 21 and 22 November 2024, Cornelius Holtorf was attending the Regional Consultation for Western Europe and North America in preparation of the UNESCO World Conference on Cultural Policies and Sustainable Development – MONDIACULT 2025, to be held 29 September – 1 October in Barcelona, Spain. I was one of three UNESCO Chairs participating in the meeting.

The meeting was introduced by the Vice-minister of Culture of the Kingdom of Spain. Mr. Jordi Martí Grau who emphasized the rights of all citizens to culture and creative work, stressing the significance of education in that respect, and that “there cannot be sustainable development without culture”. Grau emphasized the rights of all citizens to culture.

The meeting was attended, among others, by the Assistant Director General for Culture (ADG Culture), UNESCO, Mr. Ernesto Ottone-Ramírez, and by representatives of Cultural Ministeries from many European countries, the U.S. and Canada. It was moderated by the representative of Andorra and featured simultaneous translation of all contributions between Spanish, English, and French.

In my own short address to the participants I emphasized the opportunities for culture, UNESCO and MONDIACULT arising from the 2024 UN Pact of the Futures. In conclusion, I suggested for MONDIACULT 2025 to

  1. integrate foresight, anticipation, and the benefits of ‘futures literacy’ in cultural policy around the world,
  2. promote the potential of culture and cultural heritage for globally addressing the needs of future generations in the context of change and transformation.

Note: an interesting background of global cultural policy development in relation to the work of UNESCO is given in Justin O’Connor’s 2024 essay on Global Cultural Policy at the Crossroads: Reflections on the Summit of the Future.

Nuclear Waste and Heritage Futures

Reconsidering the Heritage Future of Nuclear Waste Hazards: A Permanent Legacy

By C. Pescatore, Affiliated Researcher and member of the UNESCO Chair on Heritage Futures at Linnaeus University

The question of “How long and how dangerous is high-level nuclear waste?” is rarely answered in full. Often, people are told that the radiation threat will diminish over time, as many radioactive products decay. While this is true to an extent, it only tells part of the story. The reality is more complex and far-reaching. Spent nuclear fuel is composed of roughly 95% uranium-238 (U-238), an isotope that behaves differently than the remaining 5% components that are much more actively decaying. Although its radioactivity may initially seem insignificant compared to more immediate hazards, over time U-238 will reconstitute its decay chain, leading to a resurgence of radioactive danger.

The radioactivity of U-238 does not simply decrease to insignificance; instead, it eventually increases as it reestablishes its broken decay-family, producing a host of hazardous progeny isotopes. For spent fuel, this increase becomes dominant beyond the one-million-year mark – well beyond the timeframe when many safety analyses have already been concluded. While safety cases often focus on the decay of radioactivity, they overlook the radioactive ingrowth that arises from U-238. This shift challenges conventional thinking and demands a refocusing of our long-term strategies for managing nuclear waste.

The implication is profound: the danger from high-level nuclear waste does not merely fade away. It transforms into a persistent, long-term alpha-, beta- and gamma-radiation hazard that requires sustained vigilance and robust containment strategies far into the future. This enduring risk calls into question assumptions about the timeframe for which safety must be maintained, extending our responsibilities across an almost unimaginable span of time.

Preserving Memory and Heritage for the Far Future

This brings us to the pressing question of heritage, memory, and how we communicate the information about high-level nuclear waste across extended time spans. Ensuring that future societies remember the existence and significance of these waste repositories requires a robust effort to preserve records, knowledge, and memory (RK&M).

One promising approach is the use of millennial time capsules strategically placed within or near repositories. These capsules can carry messages, warnings, and cultural artifacts that bridge the gap between our time and a distant future. Some capsules could be constructed from the same materials as the waste containers and placed within the repository to offer a final, deeply embedded source of knowledge that future discoverers might encounter, potentially guiding their understanding and actions.

Near-surface capsules could further engage communities through rituals of memory preservation and periodic inspections, creating cultural continuity and reinforcing the message of caution. Historical examples like the Osaka Castle Dual Time Capsule illustrate how science and cultural heritage can blend to transmit knowledge across generations.

However, even with the best physical and cultural tools at our disposal, the fundamental question remains: How do we effectively communicate the danger posed by these wastes across millennia? Symbols, language, stories, and rituals may change, but the risk endures. Preserving memory is not just a technical challenge; it is a societal one, requiring us to create a living “heritage future” of caution, awareness, and responsibility – one that future generations can draw upon to protect themselves from the enduring radiation hazard that lies beneath.

Kultursektorns beredskap för fred

2024-11-08

Den 16 oktober 2024 var jag inbjuden att delta på Länsmuseernas höstmöte i Uddevalla. Mötets tema var ‘Länsmuseerna i en brytningstid – kultur, motståndskraft och innovation’. Under en session med rubriken Kulturarvets beredskap för krig och fred höll jag ett anförande där jag ställde frågan om Länsmuseerna och den svenska kultursektorn gör tillräckligt just nu för att förebygga krig.


På grund av Zoom-formatet och den begränsade tiden var det svårt att föra en fördjupad diskussion med publiken. Sedan dess har två deltagare skickat in en gemensam skriftlig kommentar, som jag har besvarat.

Heritage Futures in Saudi Arabia

2024-11-02

I spent three days in AlUla in Saudi Arabia, on invitation of the Royal Commission for AlUla (RCU) to attend the AlUla World Archaeology Symposium 2024. The Royal Commission is extremely well resourced to shape AlUla’s Future, thanks to the Government of the Royal Family. They paid all costs of the Symposium participants and hired a charter jet to get them there from Ryadh (whereas I was driven 300 km through the nightly desert from Medina).

AlUla (also al-Ula) is an ancient Arabian oasis city with some spectacular archaeological sites from various periods as well as additional attractions. The idea is to develop it as a tourism destination until 2030 – which is the year the Saudi King and Crown-Prince’s “Vision 2030” is aiming at.

Vision 2030, they say, “is a blueprint that is diversifying the economy, empowering citizens, creating a vibrant environment for both local and international investors, and establishing Saudi Arabia as a global leader”. The Vision even incorporates comprehensive reforms in the public sector, the economy, and society.

Like other Gulf States (I saw this even last year in Dubai), bold visions are modernising the region at a fast pace and changes, for example regarding women rights, are already visible. The region is engulfed (!) in future visions of the kind that have become practically forgotten in Western countries dominated by either apocalyptic fears or initiatives to maintain the status quo.

The idea for AlUla, according to the RCU is this: “By safeguarding AlUla’s unique heritage and natural features, we aim to generate economic growth and sustainable development. Our strategies are crafted to not only protect but also enhance AlUla’s environmental and historical integrity, ensuring every initiative aligns with sustainable principles. This thoughtful approach positions AlUla as a model for preservation and progress, where its past informs its future.”

They actually take this very seriously, commission a number of comprehensive archaeological research projects in the area and are doing their best to work sustainably in various ways (obviously less so regarding carbon footprint…).

We are invited for the sake of product development and marketing as AlUla is trying to set itself up as the Place of Heritage for the World (as on the incription above) and the Archaeology capital of the world (as they have it on another occasion). The RCU is ambitious in its aspirations, has much archaeology to study and show to visitors, and they also have come far in many ways already.

The experience we get is certainly very different compared to what we see about Saudi Arabia in our media. I am thinking about the BRICS alliance and their claim to manifest an emerging multipolar world. While the old Western powers are increasingly in political, economical and cultural (?) crises, perhaps even decline, there is a perceptible momentum towards fast future development in the Gulf. Interestingly, they embrace culture and heritage (rather than cut budgets which we have become familiar with in Europe by now). A new world order may indeed be emerging, and in Saudi Arabia we saw it being crafted right now.

Some questions remain for Saudi Arabia to work through more fully, e.g. about the exact role of the local community and the human rights record of the government. But it is impressive nonetheless that they have entered a path for change, not just focussing on the economy but also embracing culture and society.

Heritage Futures in the making! Very interesting to see it happening.
