Climate change research in bilateral development programmes: experiences from India and Peru

Muccione, Veruska ; Orlowsky, Boris ; Allen, Simon K. ; Huggel, Christian ; Salzmann, Nadine ; Montoya, Nilton ; Randhawa, Surjeet Singh ; Stoffel, Markus

In: Development in Practice, 2019, vol. 29, no. 3, p. 336–348

This article reflects on the merits and shortfalls of bilateral research programmes aimed at strengthening climate change research capabilities, using the experience from two programmes, the PACC and IHCAP in Peru and India, respectively. The study highlights key aspects of these types of bilateral programmes, namely: capacity; performance, salary and appreciation; funding; bureaucracy and...

Rapid decline of snow and ice in the tropical Andes – Impacts, uncertainties and challenges ahead

Vuille, Mathias ; Carey, Mark ; Huggel, Christian ; Buytaert, Wouter ; Rabatel, Antoine ; Jacobsen, Dean ; Soruco, Alvaro ; Villacis, Marcos ; Yarleque, Christian ; Timm, Oliver Elison ; Condom, Thomas ; Salzmann, Nadine ; Sicart, Jean-Emmanuel

Glaciers in the tropical Andes have been retreating for the past several decades, leading to a temporary increase in dry season water supply downstream. Projected future glacier shrinkage, however, will lead to a long-term reduction in dry season river discharge from glacierized catchments. This glacier retreat is closely related to the observed increase in high-elevation, surface air...

Toward mountains without permanent snow and ice

Huss, Matthias ; Bookhagen, B. ; Huggel, Christian ; Jacobsen, D. ; Bradley, R.S. ; Clague, J.J. ; Vuille, M. ; Buytaert, W. ; Cayan, D. R. ; Greenwood, G. ; Mark, B. G. ; Milner, A.M. ; Weingartner, R. ; Winder, M.

The cryosphere in mountain regions is rapidly declining, a trend that is expected to accelerate over the next several decades due to anthropogenic climate change. A cascade of effects will result, extending from mountains to lowlands with associated impacts on human livelihood, economy, and ecosystems. With rising air temperatures and increased radiative forcing, glaciers will become smaller...

The freezing level in the tropical Andes, Peru: An indicator for present and future glacier extents: the freezing level in the tropical Andes

Schauwecker, Simone ; Rohrer, Mario ; Huggel, Christian ; Endries, Jason ; Montoya, Nilton ; Neukom, Raphael ; Perry, Baker ; Salzmann, Nadine ; Schwarb, Manfred ; Suarez, Wilson

In: Journal of Geophysical Research: Atmospheres, 2017, vol. 122, no. 10, p. 5172–5189

Along with air temperatures, the freezing level height (FLH) has risen over the last decades. The mass balance of tropical glaciers in Peru is highly sensitive to a rise in the FLH, mainly due to a decrease in accumulation and increase of energy for ablation caused by reduced albedo. Knowledge of future changes in the FLH is thus crucial to estimating changes in glacier extents. Since in situ...

Glacier monitoring and capacity building: important ingredients for sustainable mountain development

Nussbaumer, Samuel U. ; Hoelzle, Martin ; Hüsler, Fabia ; Huggel, Christian ; Salzmann, Nadine ; Zemp, Michael

In: Mountain Research and Development, 2017, vol. 37, no. 1, p. 141–152

Glacier observation data from major mountain regions of the world are key to improving our understanding of glacier changes: they deliver fundamental baseline information for climatological, hydrological, and hazard assessments. In many mountain ecosystems, as well as in the adjacent lowlands, glaciers play a crucial role in freshwater provision and regulation. This article first presents the...

Scientific knowledge and knowledge needs in climate adaptation policy: a case study of diverse mountain regions

Muccione, Veruska ; Salzmann, Nadine ; Department of Geosciences, University of Fribourg, Switzerland ; Huggel, Christian

In: Mountain Research and Development, 2016, vol. 36, no. 3, p. 364–375

Mountain ecosystems around the world are recognized to be among the most vulnerable to the impacts of climate change. The need to develop sound adaptation strategies in these areas is growing. Knowledge from the natural sciences has an important role to play in the development of adaptation strategies. However, the extent of and gaps in such knowledge have not been systematically investigated...
