Book Description
Many cities in Latin America and the Caribbean are experiencing a water crisis as sources become exhausted or degraded. Urbanization, deteriorating infrastructures with a lack of funds for repairs, and inadequate polices are conspiring to cause water shortages. People are becoming concentrated in megacities, such as Mexico City with a population of almost 23 million, that have outgrown their water-supply systems. Urban areas are increasingly incapable of supplying water and sewer systems for their populations. By the year 2020, more than 500 million inhabitants of Latin America (two-thirds of.

Book Description
One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

Book Description
This book discusses the Lagoa Santa Karst, which has been internationally known since the pioneering studies of the Danish naturalist Peter Lund in the early 1800s. It covers the speleogenesis, geology, vegetation, fauna, hydrogeology, geomorphology, and anthropogenic use of the Lagoa Santa Karst and is the first English-language book on this major karst area. The area, which has been at the heart of the debate on the origin and age of human colonization in the Americas, is characterized by a classical and scenic karst landscape with limestone cliffs, karst lakes and karst plains, in addition to numerous solution dolines. More than 1,000 caves have been documented in the area, many with significant archeological and paleontological value. Despite its great importance, the Lagoa Santa Karst faces severe environmental threats due to limestone mining and the expansion of the metropolis of Belo Horizonte and its surrounding towns. The growing recognition of the area’s remarkable significance has led to increasing concern, and a number of protected areas have now been established, improving the conservation status of this landmark karst area.

Book Description
In The Color of Modernity, Barbara Weinstein focuses on race, gender, and regionalism in the formation of national identities in Brazil; this focus allows her to explore how uneven patterns of economic development are consolidated and understood. Organized around two principal episodes—the 1932 Constitutionalist Revolution and 1954’s IV Centenário, the quadricentennial of São Paulo’s founding—this book shows how both elites and popular sectors in São Paulo embraced a regional identity that emphasized their European origins and aptitude for modernity and progress, attributes that became—and remain—associated with “whiteness.” This racialized regionalism naturalized and reproduced regional inequalities, as São Paulo became synonymous with prosperity while Brazil’s Northeast, a region plagued by drought and poverty, came to represent backwardness and São Paulo’s racial “Other.” This view of regional difference, Weinstein argues, led to development policies that exacerbated these inequalities and impeded democratization.

Book Description
As ecology becomes the new engineering, the projection of landscape as infrastructure—the contemporary alignment of the disciplines of landscape architecture, civil engineering, and urban planning— has become pressing. Predominant challenges facing urban regions and territories today—including shifting climates, material flows, and population mobilities, are addressed and strategized here. Responding to the under-performance of master planning and over-exertion of technological systems at the end of twentieth century, this book argues for the strategic design of "infrastructural ecologies," describing a synthetic landscape of living, biophysical systems that operate as urban infrastructures to shape and direct the future of urban economies and cultures into the 21st century. Pierre Bélanger is Associate Professor of Landscape Architecture and Co-Director of the Master in Design Studies Program at Harvard University’s Graduate School of Design. As part of the Department of Landscape Architecture and the Advansed Studies Program, Bélanger teaches and coordinates graduate courses on the convergence of ecology, infrastructure and urbanism in the interrelated fields of design, planning and engineering. Dr. Bélanger is author of the 35th edition of the Pamphlet Architecture Series from Princeton Architectural Press, GOING LIVE: from States to Systems (pa35.net), co-editor with Jennifer Sigler of the 39th issue of Harvard Design Magazine, Wet Matter, and co-author of the forthcoming volume ECOLOGIES OF POWER: Mapping Military Geographies & Logistical Landscapes of the U.S. Department of Defense. As a landscape architect and urbanist, he is the recipient of the 2008 Canada Prix de Rome in Architecture and the Curator for the Canada Pavilion ad Canadian Exhibition, "EXTRACTION," at the 2016 Venice Architecture Biennale (extraction.ca).

Book Description
Elizabeth DeLoughrey invokes the cyclical model of the continual movement and rhythm of the ocean (‘tidalectics’) to destabilize the national, ethnic, and even regional frameworks that have been the mainstays of literary study. The result is a privileging of alter/native epistemologies whereby island cultures are positioned where they should have been all along—at the forefront of the world historical process of transoceanic migration and landfall. The research, determination, and intellectual dexterity that infuse this nuanced and meticulous reading of Pacific and Caribbean literature invigorate and deepen our interest in and appreciation of island literature. —Vilsoni Hereniko, University of Hawai‘i "Elizabeth DeLoughrey brings contemporary hybridity, diaspora, and globalization theory to bear on ideas of indigeneity to show the complexities of ‘native’ identities and rights and their grounded opposition as ‘indigenous regionalism’ to free-floating globalized cosmopolitanism. Her models are instructive for all postcolonial readers in an age of transnational migrations." —Paul Sharrad, University of Wollongong, Australia Routes and Roots is the first comparative study of Caribbean and Pacific Island literatures and the first work to bring indigenous and diaspora literary studies together in a sustained dialogue. Taking the "tidalectic" between land and sea as a dynamic starting point, Elizabeth DeLoughrey foregrounds geography and history in her exploration of how island writers inscribe the complex relation between routes and roots. The first section looks at the sea as history in literatures of the Atlantic middle passage and Pacific Island voyaging, theorizing the transoceanic imaginary. The second section turns to the land to examine indigenous epistemologies in nation-building literatures. Both sections are particularly attentive to the ways in which the metaphors of routes and roots are gendered, exploring how masculine travelers are naturalized through their voyages across feminized lands and seas. This methodology of charting transoceanic migration and landfall helps elucidate how theories and people travel, positioning island cultures in the world historical process. In fact, DeLoughrey demonstrates how these tropical island cultures helped constitute the very metropoles that deemed them peripheral to modernity. Fresh in its ideas, original in its approach, Routes and Roots engages broadly with history, anthropology, and feminist, postcolonial, Caribbean, and Pacific literary and cultural studies. It productively traverses diaspora and indigenous studies in a way that will facilitate broader discussion between these often segregated disciplines.

Book Description
Sustainable Cities simultaneously tackles two issues of immediate public concern which also find themselves high on the policy agenda: sustainable environmental development and urban development. The themes of the book - the bringing together of the insights of environmental science, the social sciences and management; the combination of problem analysis with practical application; and a critique of urban environmental problems concentrating on air and water pollution - are illustrated throughout with in-depth material and case studies taken from around the world and are approached from a variety of perspectives: economic, ecological and managerial. Each chapter has a concluding section pointing to key concepts, key reading and a range of discussion points.
