Book Description
Uses conventional data, oral history and photographic records to examine the interactions between people and their environment over a period of 60 years. Challenges the view that population growth inevitably leads to environmental deterioration. Features valuable lessons on how resource management technologies, the right social and economic milieu and supportive policies can lead to sustainable development.

Book Description
Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

Book Description
This book takes a new approach on understanding causes of extreme poverty and promising actions to address it. Its focus is on marginality being a root cause of poverty and deprivation. “Marginality” is the position of people on the edge, preventing their access to resources, freedom of choices, and the development of capabilities. The book is research based with original empirical analyses at local, national, and local scales; book contributors are leaders in their fields and have backgrounds in different disciplines. An important message of the book is that economic and ecological approaches and institutional innovations need to be integrated to overcome marginality. The book will be a valuable source for development scholars and students, actors that design public policies, and for social innovators in the private sector and non-governmental organizations.

Book Description
This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.

Book Description
Introducing Human Geographies is the leading guide to human geography for undergraduate students, explaining new thinking on essential topics and discussing exciting developments in the field. This new edition has been thoroughly revised and updated and coverage is extended with new sections devoted to biogeographies, cartographies, mobilities, non-representational geographies, population geographies, public geographies and securities. Presented in three parts with 60 contributions written by expert international researchers, this text addresses the central ideas through which human geographers understand and shape their subject. Part I: Foundations engages students with key ideas that define human geography’s subject matter and approaches, through critical analyses of dualisms such as local-global, society-space and human-nonhuman. Part II: Themes explores human geography’s main sub-disciplines, with sections devoted to biogeographies, cartographies, cultural geographies, development geographies, economic geographies, environmental geographies, historical geographies, political geographies, population geographies, social geographies, urban and rural geographies. Finally, Part III: Horizons assesses the latest research in innovative areas, from mobilities and securities to non-representational geographies. This comprehensive, stimulating and cutting edge introduction to the field is richly illustrated throughout with full colour figures, maps and photos. These are available to download on the companion website, located at www.routledge.com/9781444135350.
