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...

Comparison of climatic trends and variability among glacierized environments in the Western Himalayas

Dimri, A. P. ; Immerzeel, W. W. ; Salzmann, Nadine ; Thayyen, R. J.

In: Theoretical and Applied Climatology, 2018, vol. 134, no. 1, p. 155–163

The climate and hydrology of the Western Himalayas is complex and a function of snow and glacier melt, land use, topography, and Indian summer and winter monsoon dynamics. Improving our knowledge about these processes is important from societal and agricultural points of view. In this study, an observational analysis is carried out to assess the changing climatic trends and the associated...

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

In: Earth-Science Reviews, 2018, vol. 176, p. 195–213

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...

Re-establishing glacier monitoring in Kyrgyzstan and Uzbekistan, Central Asia

Hoelzle, Martin ; Azisov, Erlan ; Barandun, Martina ; Huss, Matthias ; Farinotti, Daniel ; Gafurov, Abror ; Hagg, Wilfried ; Kenzhebaev, Ruslan ; Kronenberg, Marlene ; Machguth, Horst ; Merkushkin, Alexandr ; Moldobekov, Bolot ; Petrov, Maxim ; Saks, Tomas ; Salzmann, Nadine ; Schöne, Tilo ; Tarasov, Yuri ; Usubaliev, Ryskul ; Vorogushyn, Sergiy ; Yakovlev, Andrey ; Zemp, Michael

In: Geoscientific Instrumentation, Methods and Data Systems, 2017, vol. 6, no. 2, p. 397–418

Glacier mass loss is among the clearest indicators of atmospheric warming. The observation of these changes is one of the major objectives of the international climate monitoring strategy developed by the Global Climate Observing System (GCOS). Long-term glacier mass balance measurements are furthermore the basis for calibrating and validating models simulating future runoff of glacierised...

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...

Estimation of snowfall limit for the Kashmir Valley, Indian Himalayas, with TRMM PR Bright Band information

Schauwecker, S. ; Rohrer, M. ; Schwarb, M. ; Huggel,, C. ; Dimri, A.P. ; Salzmann, Nadine

In: Meteorologische Zeitschrift, 2016, p. 501–509

Knowing the height of the snowfall limit during precipitation events is crucial for better understanding a number of hydro-climatic processes, for instance glacier-climate interactions or runoff from high mountain catchments. However, knowledge on heights of the phase change during precipitation events is limited by the small number of meteorological measurements available at high altitudes,...

Semi-automated calibration method for modelling of mountain permafrost evolution in Switzerland

Marmy, Antoine ; Rajczak, Jan ; Delaloye, Reynald ; Hilbich, Christin ; Hoelzle, Martin ; Kotlarski, Sven ; Lambiel, Christophe ; Noetzli, Jeannette ; Phillips, Marcia ; Salzmann, Nadine ; Staub, Benno ; Hauck, Christian

In: The Cryosphere, 2016, vol. 10, no. 6, p. 2693–2719

Permafrost is a widespread phenomenon in mountainous regions of the world such as the European Alps. Many important topics such as the future evolution of permafrost related to climate change and the detection of permafrost related to potential natural hazards sites are of major concern to our society. Numerical permafrost models are the only tools which allow for the projection of the future...

Robust climate scenarios for sites with sparse observations: a two-step bias correction approach

Rajczak, Jan ; Kotlarski, Sven ; Salzmann, Nadine ; Schär, Christoph

In: International Journal of Climatology, 2016, vol. 36, no. 3, p. 1226–1243

Observed and projected climatic changes demand for robust assessments of climate impacts on various environmental and anthropogenic systems. Empirical-statistical downscaling (ESD) methods coupled to output from climate model projections are promising tools to assess impacts at regional to local scale. ESD methods correct for common model deficiencies in accuracy (e.g. model biases) and scale...
