[en] The process of disappearance of the Pyrenean glaciers is increasingly evident. According to the latest studies, they could disappear by the middle of the 21st century, as the processes of retreat have been occurring very rapidly in recent years. The disappearance of glaciers will mean a great change in the cultures and customs of high mountain areas and populations around the world. Glaciers are important elements in these areas, both visually and in terms of the popularity they give to the territory. The case of the Aneto and Maladeta glaciers is no exception and, as will be explained below, their disappearance may have consequences for the population, mountain communities and tourist attraction of the Posets-Maladeta Natural Park and its surroundings. Among the contributions of nature to the human being there is a group of non-materials. This paper will analyze how the disappearance of glaciers will affect these contributions. Several non-material contributions from the Aneto and Maladeta glaciers in the Posets and Maladeta Natural Park have been defined, taking into account the classification Nature's Contributions to People. These contributions, in our case, in the environment of Aneto and Maladeta, are beneficial. The non-material contributions have been divided into three areas of work: knowledge, experience and sense of belonging and identity. The aim of this work will be to analyse the benefits they offer at present and the consequences of the disappearance of the glaciers. For this purpose, a study will be carried out through a survey. The survey has been disseminated among the people who have visited the park and each one has made their assessment. This way we will be able to know and measure the importance of the intangible contributions of the glaciers. With these data we will be able to know the impact of the disappearance of the glaciers on these contributions and make a developed evaluation of the importance of the glaciers, in this case for the society and the management of the Posets-Maladeta Park. On the other hand, according to the data obtained, the most serious consequences of the disappearance of the glaciers are related to the experiences of the glacier itself, that is, scientific knowledge, hiking, mountaineering, mountaineering, etc. These are the most valued contributions of the glaciers, based on the experiences lived in them. In addition, the disappearance of the glaciers will have other consequences on the flow of visitors: if it decreases, it can affect the economy of the whole valley. In summary, this work shows the consequences of the disappearance of the glaciers as a consequence of climate change, of the non-material contributions of nature to society in the Posets and Maladeta Natural Park. The study of the Posets-Maladeta Park and its glaciers has been selected as a research case to understand similar processes that are taking place in other mountain areas of the planet.

[eu] Pirinioetako glaziarren desagertze prozesua geroz eta nabarmenagoa da. Azken ikerketen arabera, hauek XXI. mendearen erdialderako desager daitezke, urtze prozesuak azken urteetan oso bizkor ematen ari baitira. Glaziarren desagertzeak mundu osoko goi mendiko eremu eta populazioetako kultura eta ohituretan aldaketa handia ekarriko du. Glaziarrak inguru hauen elementu garrantzitsuak baitira, bai bisualki, baina baita hauek lurraldeari ematen dioten ospearengatik ere. Aneto eta Maladetako glaziarren kasua ez da salbuespena, eta, ondoren azalduko den bezala, hauen desagertzeak hainbat ondorio utzi ditzake populazioan, mendiko komunitateetan eta Posets eta Maladeta Parke Naturaleko erakargarritasun turistikoan eta honen inguruetan. Naturak gizakiari egiten dizkion ekarpenen artean ekarpen ez-materialen talde bat dago. Lan honetan, hain zuzen ere, glaziarren desagerpenak ekarpen horiei nola eragingo dien aztertuko da. Aneto eta Maladetako glaziarrek Posets eta Maladateko Parke Naturalean egiten dituzten hainbat ekarpen ez-material definitu dira, Nature´s Contributions to People sailkapena kontuan izanik. Ekarpen ez-material hauek, gure kasuan, hau da, Aneto eta Maladetako inguruan, onuragarriak dira. Ekarpen hauek hiru arloetan banatu dira lan honetan: ezagutza, esperientzia eta parte izatearen sentimendua eta identitatea. Lan honen helburua ekarpen hauek aztertzea izango da: alde batetik, gaur egun eskaintzen dituzten onurak eta, bestetik, glaziarrak desagertzeak ekarriko dituen ondorioak. Honetarako, inkesta baten bidez garatutako azterketa bat egingo da. Inkesta parkea bisitatu duen jendearen artean zabaldu da eta bakoitzak bere balorazioa egin du. Horrela, glaziarren ekarpen ez-materialen garrantzia jakin eta neurtu ahal izango dugu. Datu hauekin, glaziarrak desagertzeak ekarpen hauekiko izango duen eragina jakin ahal izango da eta, modu horretan, balorazio garatu bat egin, glaziarren garrantzia aipatuz, kasu honetan gizartearentzat eta Posets-Maladeta Parkearen kudeaketarentzat. Bestalde, lortutako datuen arabera, glaziarren desagertzearen ondorio larrienak glaziarrean bertan ematen diren ekarpenekin lotu dira, hau da, ezagutza zientifikoarekin, mendi ibilaldiarekin, mendizaletasunarekin, alpinismoarekin, etab. Hauek baitira glaziarren ekarpenetatik jendeak gehien baloratzen dituenak, alegia, bertan bizitutako esperientzietan oinarritutakoak. Gainera, glaziarren desagerpenak beste hainbat ondorio ere izango ditu inguruan, adibidez, bisitarien fluxuari dagokiona: hau gutxitzen bada, bailara osoko ekonomiari eragin diezaioke. Laburbilduz, aldaketa klimatikoaren ondorioz, glaziarren desagertzeak, Posets eta Maladetako Parke Naturalean naturak gizarteari egiten dizkion ekarpen ez-materialek zer nolako ondorioak izango dituzten azalduko da lan honetan. Posets-Maladeta Parkearen eta bere glaziarren azterketak planetako beste mendi eremuetan gertatzen ari diren antzeko prozesuak ulertzeko ikerketa-kasu bezala hautatu da.
