Retreat of Mediterranean glaciers since the Little Ice Age: Case study of Ghiacciaio del Calderone (Central Apennines, Italy)

Ghiacciaio del Calderone is the only glacier in the Italian Apennines and the southernmost glacier in Europe in a strong reduction phase. In this paper, the authors present a tentative synthesis of the evolution of the glacier, with a particular focus on evaluating the variations in area and thickness ranging from the end of the Little Ice Age to the present. The analysis was performed in a...

The challenges of mountain environments: Water, natural resources, hazards, desertification and the implications of climate change

Mountain ecosystems are a biosphere reserve. They harbor a wide range of significant resources including animals, plants as well as minerals. Mountains are home to about 10 percent of the global population. A significant high proportion of 25 - 30 percent directly depends on the resources flowing from mountain regions. Functionally, mountains play a critical role in the environment and...

Cs-137 gamma peak detection in snow layers on Calderone Glacier
The Calderone Glacier, located in the Gran Sasso d'Italia mountain group (Abruzzo, Italy), is the most southern glacier in Europe. The reduced dimension and the general conditions of the glacier make it a powerful environmental indicator in evaluating global change processes including the radio-chemical pollution induced by human activity. Two high altitude samples of snow, collected during...
The historical and iconographic research in the reconstruction of the variation of the Calderone Glacier: State of the art and perspective
The Calderone Glacier is characterised by a reduction phase since the end of the "Little Ice Age" (LIA) Auct., particularly strong during the last decade. In fact during the nineties a set of multidisciplinary researches started to evaluate the role of the Glacier like an indicator of the effects of human activities and finally of regional and global climatic change. The apparatus is now confined...
Himalayan ecohydrology: An emerging subject for restoration of the mountain system
The article briefly deals with the Himalayan Mountain System and the associated natural hazards due to huge snow and glacier fields at the highest elevation. Due to inherent sensitivity of these apex systems to global climatic change, emphasis is laid to initiate interdisciplinary research in hydrology affecting ecology and environment. Recommendations of a Regional Working Group on Mountain...
The strong reduction phase of the Calderone Glacier during the last two centuries: Reconstruction of the variation and of the possible scenarios with GIS technologies
The paper presents the state of the art of the works in progress; in particular Prof. L. D'Alessandro co-ordinates geomorphologic topics, Dr. Massimo Pecci field activities and data elaboration in GIS environment and Prof. C. Smiraglia glaciological themes. The Calderone glacier is now confined into a deep central mountain valley of the Gran Sasso d'Italia, with steep walls, and does not show...
Advance and retreat phases of the Karakorum glaciers during the 20th century: Case studies in the Braldo Valley, Pakistan

Variation that took place at the terminus of some Karakorum glaciers (particularly the Baltoro glacier and the Liligo glacier) during the present century has been reconstructed using several methodologies. The two glaciers studied have shown different behaviors at the termini, at least regarding the rate of displacement. The Baltoro is one of the longest glaciers on the Earth, excluding Artic...

Modeling the energy balance of high altitude glacierised basins in the Central Andes
Water as a result of snow and glacier melt is an important resource in the Central Andes of Chile and Argentina, which in terms of precipitation are close to climatic deserts, yet they support large populations and a rich agriculture. In spite of this, little is known of the processes at play and the variability over time. In particular, the specific mechanisms of energy balance and melt on high...
Sustainable development and management of water resource in mountain ecosystem: Some examples from Sikkim Himalaya

Water is vital for increasing the agricultural production. It is also in great demand for domestic and industrial use. Further it is an important medium for generating cheap hydroelectric power. Water is thus regarded as a resource among resources as all other resource bases have no meaning without this resource and life is not possible in its absence. The supply of drinking water to rural and...
