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
Climate change is producing profound changes globally. Yet we still know little about how it affects real people in real places on a daily basis because most of our knowledge comes from scientific studies that try to estimate impacts and project future climate scenarios. This book is different, illustrating in vivid detail how people in the Andes have grappled with the effects of climate change and ensuing natural disasters for more than half a century. In Peru's Cordillera Blanca mountain range, global climate change has generated the world's most deadly glacial lake outburst floods and glacier avalanches, killing 25,000 people since 1941. As survivors grieved, they formed community organizations to learn about precarious glacial lakes while they sent priests to the mountains, hoping that God could calm the increasingly hostile landscape. Meanwhile, Peruvian engineers working with miniscule budgets invented innovative strategies to drain dozens of the most unstable lakes that continue forming in the twenty first century. But adaptation to global climate change was never simply about engineering the Andes to eliminate environmental hazards. Local urban and rural populations, engineers, hydroelectric developers, irrigators, mountaineers, and policymakers all perceived and responded to glacier melting differently-based on their own view of an ideal Andean world. Disaster prevention projects involved debates about economic development, state authority, race relations, class divisions, cultural values, the evolution of science and technology, and shifting views of nature. Over time, the influx of new groups to manage the Andes helped transform glaciated mountains into commodities to consume. Locals lost power in the process and today comprise just one among many stakeholders in the high Andes-and perhaps the least powerful. Climate change transformed a region, triggering catastrophes while simultaneously jumpstarting modernization processes. This book's historical perspective illuminates these trends that would be ignored in any scientific projections about future climate scenarios.

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
This monograph reviews the nature of Quaternary environmental changes over the largest continent in the Southern Hemisphere. Moreover, since South America makes a transect across most climatic belts of an entire hemisphere, it provides a unique opportunity to examine the impact of changing Quaternary climates on a variety of environments. It also forms the basis for judging the synchrony or non-synchrony of Quaternary climatic changes between hemispheres and this has important implications for climatic modelling.As South America has a dynamic tectonic regime along its western margin, 3 chapters discuss the geomorphological impact of Quaternary tectonics and volcanism. The following 6 chapters integrate evidence for Quaternary changes in the great alluvial basins of the Continent Orinoco, Amazon, Paranaacute;) and in the contiguous highland massifs (Guyana, Brazil, Patagonia). As parts of the Andes have been high enough to support glaciers since the late Miocene, 5 chapters review the nature and consequences of Quaternary glacier fluctuations. The following 4 chapters select major process-form systems that impacted the continent during the Quaternary, including geocryogenic activity, palaeolake development, palaeo-gravel formations and coastal changes. Three chapters provide the first major review of Quaternary vegetation changes in South America (primarily the Andes) deduced from palaeoecological data. The final chapter weaves most of the environmental threads together in an overall synthesis of the Quaternary of South America.The book is lavishly illustrated with photographs and line diagrams. As it provides a compendium of data and analyses about Quaternary changes for a whole continent, this book should appeal to a wide range of environmental disciplines.

Book Description
Anomalous climatic outcomes such as higher temperatures, intense rainfall and flood, frequent and severe droughts are now at the new level. Without appropriate adaptation measures, climate change is bound to exacerbate vulnerability of society, place food security and human health at risk, threaten the lives of growing urban population and impede the goal of attaining sustainable development. The human and social dimensions of climate change, including climate policy, are essential parts of our response to the many challenges emanating from climate change. By focusing on a wide range of topics and involving a diverse array of scholars, this book sheds lights on human and social dimensions of climate change; topics neglected and often poorly understood by scholars and policymakers.
