Limnological research carried out jointly by Nepal and Italian scientists under auspicious of RONAST/Ev-K2-CNR Project following the establishment of “Piramid Laboratory” in 1990 in Lobuche at a height of 5050 m at the foot of Mount Everest, one the highest inhabited places in the world, marks a major contribution in the field of limnological research in Nepal. The aim of this book is, instead, to collect in an integrated database all the currently available information on the limnology of high-altitude freshwater lakes. This will be the first time it has been attempted to produce such a large database on these remote lakes, which lie at an altitude of about 4000-6000 m a.s.l. In fact, 69 of the 90 lakes mapped in the area of the Mt Everest Region have been sampled and analysed for chemical and biological parameters, using uniform techniques. This database will contribute to filling the gaps in our present knowledge and furthering our understanding of human impact in remote areas

The informations are based on the "Khumbu Himalaya lake cadastre", build in the framework of the EvK2- CNR Strategic Project and publicized in G.A.Tartari et al. Lake cadastre of Khumbu Himal Region: geographical - geological - limnological data base, in A. Lami & G. Giussani (Guest Editors) Limnology of high altitude lakes in the Mt Everest Region (Nepal) Mem. Ist. ital. Idrobiol.: 57: 151-2351998. The article is available for download and the complete publication is collected and described in the SHARE Geonetwork database under the category "Publication".

This Work Package of the SHARE Stelvio Project, managed by ISE-CNR research group is focus on fresh water resources (i.e.: rivers and lakes) to describe their chemical, physical and biological features and to look for relations with recent atmosphere, climate and cryosphere variability.

The most remote regions of globe represent some of the least disturbed ecosystems, yet they are threatened by air pollution and by climatic change. The Himalaya is one of the most isolated regions in the world and least explored wildernesses outside the Polar Regions; and it is for this reason that the Tibetan Plateau is often referred to as the ‘Third Pole’. Limnological survey (including chemistry, biology and sediment core studies) of lakes located between ca. 4500 and 5500 m a.s.l. has been performed from 1992 in the Kumbhu Valley, Nepal. Lake water chemical surveys reveal a constant increase of the ionic content of the lake water probably related to glacier retreat. Modern phytoplankton data compared with previous data point to an increasing trend in lake productivity. Zooplankton, benthos and thechamoebians provide useful biogeographical information. Paleolimnological reconstructions show the potential use of these sites in providing proxy data of past climatic changes in high altitude regions. Data collected of persistent organic pollutants show that the studied sites receive input related to long-range transport pollution. The aims and rationale for the future development of the Ev-K2-CNR Limnological Information System is discussed.
