Book Description
This Atlas illustrates the significant reduction in glacier mass happening throughout the Andean region. It quantifies the contribution of glaciers to drinking water supplies in cities and to agriculture, hydropower and industries. A reduction in glacier mass results in a long-term reduction in seasonal melt water - which is the mainstay of livelihoods for millions of people.

Book Description
Glaciers and ice sheets have been melting significantly during recent decades, posing environmental threats at local, regional and global scales. Changes in glaciers are one of the clearest indicators of alterations in regional climate, since they are governed by changes in accumulation (from snowfall) and ablation (by melting of ice).

Book Description
This book is the last of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared.The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. Where controversial interpretations are possible, such as for High Asia, they are indicated. All information on Quaternary glaciations worldwide is presented for the first time in a uniform format, including the mountain glaciations of regions such as Costa Rica, Ethiopia or Taiwan. The digital maps in this volume cover Latin America, Asia, Africa, Australasia, Antarctica. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.Also available: Part I: Europe, ISBN 0-444-51462-7 Part II: North America, ISBN 0-444-51592-5

Book Description
Glaciers in the Andes are particularly important natural archives of present and past climatic and environmental changes, in significant part because of the N-S trend of this topographic barrier and its influence on the atmospheric circulation of the southern hemisphere. Strong gradients in the seasonality and amount of precipitation exist between the equator and 30° S. Large differences in amount east and west of the Andean divide also occur, as well as a change from tropical summer precipitation (additionally modified by the seasonal shift of the circulation belts) to winter precipitation in the west wind belt (e. g. , Yuille, 1999; Garraud and Aceituno, 2001). The so-called 'dry axis' lies between the tropical and extra tropical precipitation regimes (Figure 1). The high mountain desert within this axis responds most sensitively to the smallest changes in effective moisture. An important hydro-meteorological feature on a seasonal to inter-annual time-scale is the occurrence of EN SO events, which strongly control the mass balance of glaciers in this area (e. g. , Wagnon et ai. , 2001; Francou et ai. , in press). The precipitation pattern is an important factor for the interpretation of climatic and environmental records extracted from ice cores, because much of this information is related to conditions at the actual time of precipitation, and this is especially so for stable isotope records. Several ice cores have recently been drilled to bedrock in this area. From Huascanin (Thompson et ai. , 1995), Sajama (Thompson et ai.

Book Description
This book focuses on Perus highest and most glacierized mountain range the Cordillera Blanca. This mountain range experienced numerous disasters in the past (e.g. lake Palcacocha outburst in 1941, earthquake-induced ice and rock avalanche from Mt. Huascarn in 1970) and attracted the attention of researchers from around the world.The 15 chapters of the book span from broadly thematic topics of geology, geomorphology, climate, hydrology and hydrogeology, lakes, glaciation, and environmental settings to more specific topics and emergent themes of relevance for the Cordillera Blanca, including studies of various types of natural hazards (landslides, GLOFs). While most of the chapters focus on biophysical processes of the natural environment, several chapters explore the complex interactions between humans and environmental factors, providing insights and perspectives from social science and the humanities. This book is unprecedently comprehensive overview of the state-of-the-art knowledge about the geo-environmental changes in the Cordillera Blanca.

Book Description
The Physical Geography of South America, the eighth volume in the Oxford Regional Environments series, presents an enduring statement on the physical and biogeographic conditions of this remarkable continent and their relationships to human activity. It fills a void in recent environmental literature by assembling a team of specialists from within and beyond South America in order to provide an integrated, cross-disciplinary body of knowledge about this mostly tropical continent, together with its high mountains and temperate southern cone. The authors systematically cover the main components of the South American environment - tectonism, climate, glaciation, natural landscape changes, rivers, vegetation, animals, and soils. The book then presents more specific treatments of regions with special attributes from the tropical forests of the Amazon basin to the Atacama Desert and Patagonian steppe, and from the Atlantic, Caribbean, and Pacific coasts to the high Andes. Additionally, the continents environments are given a human face by evaluating the roles played by people over time, from pre-European and European colonial impacts to the effects of modern agriculture and urbanization, and from interactions with El Niño events to prognoses for the future environments of the continent.

Book Description
The Middle Holocene epoch (8,000 to 3,000 years ago) was a time of dramatic changes in the physical world and in human cultures. Across this span, climatic conditions changed rapidly, with cooling in the high to mid-latitudes and drying in the tropics. In many parts of the world, human groups became more complex, with early horticultural systems replaced by intensive agriculture and small-scale societies being replaced by larger, more hierarchial organizations. Climate Change and Cultural Dynamics explores the cause and effect relationship between climatic change and cultural transformations across the mid-Holocene (c. 4000 B.C.). - Explores the role of climatic change on the development of society around the world - Chapters detail diverse geographical regions - Co-written by noted archaeologists and paleoclimatologists for non-specialists
