#RECHERCHE 🌿 Une étude de Benjamin Gwinneth, professeur au Département de géographie, montre qu’à Itzan au nord du Guatemala, la population maya a chuté sans sécheresse remettant en question la thèse climatique classique du déclin maya.

The collapse of Maya civilization: drought doesn’t explain everything Research by UdeM’s Benjamin Gwinneth calls for a reconsideration of purely climate-based explanations for why the lowland population of Central America went into major decline.

#GEOGRAPHY "The transformation or 'collapse' of Maya civilization was not a mechanical result of a uniform climate catastrophe," @gwinneth.bsky.social finds. "It was a complex phenomenon in which ... socio-political and economic factors played a decisive role." nouvelles.umontreal.ca/en/article/2...

Effondrement de la civilisation maya: la sécheresse n’explique pas tout Selon une étude de Benjamin Gwinneth, certaines régions mayas ont vu leur population chuter sans connaître de sécheresse, ce qui remet en question les explications climatiques de ce déclin.

#SOCIÉTÉ | 🌎🔍 Quand un mystère refait surface

Une étude remet en question l’idée que la sécheresse explique l’effondrement #maya. À #Itzan, aucune trace de sécheresse. Pourtant, la population s’est effondrée. Les causes seraient plutôt sociales et politiques.

The collapse of Maya civilization: Drought doesn't explain everything Between 750 and 900 CE, the population of the Maya lowlands in Central America experienced a major demographic and political decline which, according to the scientific literature, coincided with repeated episodes of intense drought.

New sediment analyses from the Maya lowlands indicate that drought alone does not account for the civilization’s collapse; interconnected social, economic, and political factors played a crucial role. doi.org/hbcrf5

‘A precarious position’: almost 3,000 species at risk of disappearing from Wales, report finds Environmental body says modest investment and changes can help preserve long list of animals, fungi and lichen Almost 3,000 species ranging from glorious birds to tiny lichen are in peril in Wales because they are clinging on in a handful of locations or even fewer, a groundbreaking report has revealed. The report from Natural Resources Wales (NRW) highlights that since the millennium, 11 species have already been lost to Cymru, including the turtle dove and belted beauty moth. It warns that 2,955 other terrestrial or freshwater species are at serious risk because they are confined to five locations or fewer. Continue reading...
