Now, fifty years later, the black and white photographs taken by these scientists are of immense value in trying to understand the impacts of climate change on the world’s highest mountain range, the Himalayas. Mountain geographer Alton Byers has revisited many of the sites of the original photographs and taken replicates, illustrating the changes in the landscape.
The old and new photographs have now been united in a unique photo exhibition: Himalaya – Changing Landscapes, currently on show at the IUCN World Conservation Congress in Barcelona. The exhibition is part of the 25th Anniversary celebrations for ICIMOD and has been organised in partnership with the BBVA Foundation.
“Only five decades have passed between the old and the new photographs and the changes are dramatic. Many small glaciers at low altitudes have disappeared entirely and many larger ones have lost around half of their volume. Some have formed huge glacial lakes at the foot of the glacier, threatening downstream communities in case of an outburst”, says Byers.
The Himalaya – Changing Landscapes photo exhibition aims to raise awareness of the impact of climate change and of the new challenges facing the mountain people. The stunning repeat panorama views of mountains and glaciers are accompanied by images of the Himalayan people and their stories, as well as photographs of the scientists conducting glacier research in the 1950s. The four-metre long photo panels making up the exhibition are located outside the Barcelona International Convention Centre, and entrance is free for conference participants and the general public alike.
Climate change is affecting people around the globe, and this is especially evident at the top of the world around Mount Everest and the high peaks of the Himalayan mountain range. The greater Himalayan region has the largest concentration of snow and ice outside the two poles. Warming temperatures cause rapid melting of the glaciers, severely affecting the people downstream. Ten river systems originating in the Himalayas bring water to a mountain population of around 200 million, while the vast water basins downstream are home to a further 1.3 billion people. In total 1.5 billion people – a fifth of the world’s population - depend on the Himalayan rivers for their water supply.
The Hindu Kush-Himalayan region is the highest, most complex mountain region in the world. It extends more than 3500km over eight countries, from Afghanistan in the north-west to Myanmar in the south-east. The area ranges from the high plateau of Tibet and other mountain areas of China to the Ganges Basin in India, and has the upland watersheds of the ten major Asian river systems.
Warming in the Himalayan region has been much greater than the global average. Weather patterns are becoming more unpredictable and extreme – dry seasons become dryer and wet seasons wetter. This phenomenon is causing concern over the long-term reduction in total water supply, affecting the lives and livelihoods of the Himalayan people, especially in agriculture practices and long-term food security.
In the words of Dr. Andreas Schild, Director General of ICIMOD; “What we see here at the Himalaya photo exhibition is just the tip of the iceberg. The changes taking place are alarming, and the time to act is now. Scientific evidence shows that the effects of globalisation and climate change are being felt in even the most remote Himalayan environments. While climate change is mostly caused by the highly industrialised parts of the world, the effects are taking their toll in the sensitive mountain areas. The signs are visible, but the in-depth knowledge and data from the Himalayan region is largely missing. Global measures of scientific co-operation and regional collaboration are needed to reduce this information gap. What happens in this remote mountain region is a serious concern for the whole world”.
The Himalaya – Changing Landscapes photo exhibition was first unveiled in a customised format at the Mt. Everest Base Camp (5300m) in April 2008, making it the highest photo exhibition in the world. After Barcelona the exhibition will travel to Kathmandu for ICIMOD’s 25th Anniversary celebrations.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
