Glaciers have carved some of Earth’s most beautiful landscapes by steepening and deepening valleys through erosion. Think of the Scottish Highlands, Yosemite National Park in the US, or the Norwegian Fjords. But big questions remain about how glacial erosion works. A problem for scientists seeking to understand how glaciers affect the landscape is that the processes of glacial erosion are very complex and not fully understood. For the most part that’s because these processes occur under tens, hundreds or even thousands of metres of ice – we simply can’t observe them.
In the Andes of Peru and adjacent arid lowlands, human subsistence often depends on year-round streamflow from glaciers and lakes, particularly in the dry season. However, global change impacts increasingly affect local hydrology and associated livelihoods which is clearly demonstrated by the impacts of glacier shrinkage. Rapidly growing lakes (Fig. 1) in deglaciating mountain regions potentially imply severe risks but also options for human livelihoods.
The bushfire crisis in Australia has dominated news headlines these past few weeks, affecting cities, towns and rural areas including the unique Australian alpine environment. This has prompted many to question what implications these fires have for these alpine ecosystems, but also the complex interactions with human dimensions and management options in a changing climate in mountain social-ecological systems.
The expansion of protected areas has significant implications for local communities and economies. How can community involvement in this process build trust and help ensure sustainable socioeconomic development, and what are the challenges that such an expansion can generate? A new research project sets out to explore this topic in the context of t...
I met Meritxell and Laia one bright sunny day in April, in the  Pallars Sobirà , a mountainous county in the Catalan Pyrenees. Both are women farmers and work in livestock management – Meritxell is a cattle rancher, while Laia herds goats and makes cheese.  Unlike most women in the region, both have made a conscious choice to live and wor...
The 2nd International Hydrological Workshop on Sustainable Water Resources Management in High Mountains in the Baltic Sea Region was held in Zakopane in the Polish Tatra Mountains from 10-13 June 2019. 
Water is essential for human life, but in many parts of the world water supplies are under threat from more extreme, less predictable weather conditions due to climate change. Nowhere is this clearer than in the Peruvian Andes, where rising temperatures and receding glaciers forewarn of imminent water scarcity for the communities that live there.
Microplastics have been discovered in a remote area of the French Pyrenees mountains. The particles travelled through the atmosphere and were blown into the once pristine region by the wind, according to a new study published in Nature Geoscience . This is just the latest example of the 'hidden risks' posed by plastics that humans cannot see with t...
In a blog post originally written for the P3 project, Marilen Haver – a PhD Student and early career scientist at P³ – describes her experience of attending the recent MRI-hosted GEO-GNOME workshop on 'Essential Climate Variables for Observations in Mountains'.
Despite centuries of persecution, indigenous groups still manage or have tenure rights over at least a quarter of the world’s land surface. Often inhabiting these lands as far back as memory extends, they share a deep and unique connection to their environment.
