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
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
In Outlandish, acclaimed travel writer Nick Hunt takes us across landscapes that should not be there, wildernesses found in Europe yet seemingly belonging to far-off continents: a patch of Arctic tundra in Scotland; the continent's largest surviving remnant of primeval forest in Poland and Belarus; Europe's only true desert in Spain; and the fathomless grassland steppes of Hungary. From snow-capped mountain range to dense green forest, desert ravines to threadbare, yellow open grassland, these anomalies transport us to faraway regions of the world. More like pockets of Africa, Asia, the Poles or North America, they make our own continent seem larger, stranger and more filled with secrets. Against the rapid climate breakdown of deserts, steppes and primeval jungles across the world, this book discovers the outlandish environments so much closer to home - along with their abundant wildlife: reindeer; bison; ibex; wolves and herds of wild horses. Blending sublime travel writing, nature writing and history - by way of Paleolithic cave art, reindeer nomads, desert wanderers, shamans, Slavic forest gods, European bison, Wild West fantasists, eco-activists, horseback archers, Big Grey Men and other unlikely spirits of place - these desolate and rich environments show us that the strange has always been near.

Book Description
Extraordinary change is under way in the Alto Urubamba Valley, a vital and turbulent corner of the Andean-Amazonian borderland of southern Peru. Here, tens of thousands of Quechua-speaking farmers from the rural Andes have migrated to the territory of the Indigenous Amazonian Matsigenka people in search of land for coffee cultivation. This migration has created a new multilingual, multiethnic agrarian society. The rich-tasting Peruvian coffee in your cup is the distillate of an intensely dynamic Amazonian frontier, where native Matsigenkas, state agents, and migrants from the rural highlands are carving the forest into farms. Language, Coffee, and Migration on an Andean-Amazonian Frontier shows how people of different backgrounds married together and blended the Quechua, Matsigenka, and Spanish languages in their day-to-day lives. This frontier relationship took place against a backdrop of deforestation, cocaine trafficking, and destructive natural gas extraction. Nicholas Q. Emlen’s rich account—which takes us to remote Amazonian villages, dusty frontier towns, roadside bargaining sessions, and coffee traders’ homes—offers a new view of settlement frontiers as they are negotiated in linguistic interactions and social relationships. This interethnic encounter was not a clash between distinct groups but rather an integrated network of people who adopted various stances toward each other as they spoke. The book brings together a fine-grained analysis of multilingualism with urgent issues in Latin America today, including land rights, poverty, drug trafficking, and the devastation of the world’s largest forest. It offers a timely on-the-ground perspective on the agricultural colonization of the Amazon, which has triggered an environmental emergency threatening the future of the planet.

Book Description
"Major compilation of historical and anthropological articles focuses on the nature of markets and exchange structures in the Andes. Prominent scholars explore Andean participation in the European market structure, the influence of migration in changing ethnic boundaries and spheres of exchange, and the politics of market exchange during the colonial period. Larson's introduction places articles within the context of Andean economic systems, while Harris concludes with an appreciation of the relationships between mestizo and indigenous ethnic identities in the context of market relations. Both introduction and conclusion lend a greater coherence to this carefully-crafted and monumental volume"--Handbook of Latin American Studies, v. 57.

Book Description
Nowhere on Earth is there an ecological transformation so swift and so extreme as between the snow-line of the high Andes and the tropical rainforest of Amazonia. The different disciplines that research the human past in South America have long tended to treat these two great subzones of the continent as self-contained enough to be taken independently of each other. Objections have repeatedly been raised, however, to warn against imagining too sharp a divide between the people and societies of the Andes and Amazonia, when there are also clear indications of significant connections and transitions between them. Rethinking the Andes–Amazonia Divide brings together archaeologists, linguists, geneticists, anthropologists, ethnohistorians and historians to explore both correlations and contrasts in how the various disciplines see the relationship between the Andes and Amazonia, from deepest prehistory up to the European colonial period. The volume emerges from an innovative programme of conferences and symposia conceived explicitly to foster awareness, discussion and co-operation across the divides between disciplines. Underway since 2008, this programme has already yielded major publications on the Andean past, including History and Language in the Andes (2011) and Archaeology and Language in the Andes (2012).
