The status of traditional silvo-pastoral systems in Malam Jabba Valley, N.W.F.P., Pakistan
The status of silvo-pastoral systems in Malam Jabba Valley, N.W.F.P., Pakistan was studied with the objective of demonstrating the complex interactions between the development of the human population of a former remote and inaccessible mountain area and the status of traditional agroforestrial landuse systems. Overpopulation and the consequent encroachment of settlements into the forested...
Mountain climate change and cryospheric responses: A review
Direct observations and proxy records indicate that historical and recent changes in climate in many mountain regions of the world are at least comparable with, and locally may be greater than, those observed in the adjacent lowlands. Actual and potential responses in cryospheric variables include: a rise in the snowline, a shorter duration of snow cover, changes in avalanche frequency and...
Recensement des études concernant les effets du climat et du réchauffement climatique sur les espaces de montagne en France métropolitaine
Review of studies on the effects of climate and climate warming on the mountain areas of France Created by legislation passed on 19 January 2007, the ONERCI was formed out of the Hill of the government to take account of questions raised by the effects of climate change. It collects information, studies and researches the risks caused by the warming climate and extreme climatic events in order...
Évolution des aléas naturels et variabilité climatique: Comment limiter l’incertitude pour les décideurs et les services techniques? Application aux Alpes françaises et suisses

Natural risks and climate variation: How to reduce uncertainty of policy-makers and technical services in the French and Swiss Alps? Some regional experiences seem. to be in contradiction with global experiences suggested in GIEC reports, which present general trends and averages. Thus if most regions are getting warmer, some are seeing their average temperatures falling. All the same, it is...

The impact of global warming on the glaciers of the Himalaya

Since industrialization and human activities is advancing the concentration of greenhouse gases in the atmosphere is steadily increasing. As a result of green house gas effect the world’s average surface temperature has increased between 0.3 and 0.6oC over the past hundred years. There is expectation of global average temperature increase by 1.4 to 5.8°C in 2100 with the increase of...

Mountain tsunamis
Glaciers worldwide are retreating in the face of accelerating global warming, as human activities cause steadily increasing concentrations of greenhouse gases in the atmosphere: their melting is an important indicator of climate change. By one forecast, up to a quarter of the global mountain glacier mass could disappear by 2050, and up to half could be lost by 2100. Changes in temperature are...
Climate change in the Columbia Basin: Starting the dialogue

Higher summer and winter temperatures, declining mountain snowpack, reduced snowfall, long, dry summers, sudden heavy rains - the residents of the Columbia River Basin in Canada are experiencing different weather conditions than in the past. They are also seeing changes in natural systems including melting glaciers, lower summer streamflows, more frequent wildfires, and outbreaks of forest...

The slippery slope of winter sports
The increasing popularity of winter sports is placing an ever increasing strain on fragile mountain ecosystems. Carmen de Jong highlights how tourism could be irreversibly changing the face of Alpine slopes around the world. This is the text of BBC Viewpoint from the BBC News (www.bbc.co.uk/) Monday, 6 August 2007
Potential effects of climate change on treeline position in the Swedish mountains
Climate change may strongly influence species distribution and, thus, the structure and function of ecosystems. This paper describes simulated changes in the position of the upper treeline in the Swedish mountains in response to predicted climate change. Data on predicted summer temperature changes, the current position of the treeline, and a digital elevation model were used to predict the...
Tackling climate change in partnership
Mountains host sensitive indicators of global climate change. As the world heats up, mountain glaciers - the source of water for many of the world’s river systems and people - are melting at unprecedented rates, while rare plants and animals struggle to survive over ever diminishing areas, and mountain people, already among the world’s most disadvantaged, face greater hardships. We cannot reverse...
