Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.

The sustainability of irrigation and drainage in the face of many variants and constraints like availability of water as a resource, ecological balance, socio-cultural impacts, and climate change effects lies in the strategies adopted and systems emplaced. It has always remained a challenge for the users of irrigation waters to maintain sustainability in quality and quantity. This book aims ?to explore frontiers of knowledge in coining sustainable strategies and systems direly needed in managing the quality and quantity of water required for crop irrigation, surface and root zone drainage and flood management using available tools of research and development?. Eminent authors and their colleagues possessing varied professional backgrounds and expertise have dealt with these issues concerning the strategies and systems of irrigation and drainage. This book will prove to be beneficial for crop growers, agricultural engineers, water resource managers, academicians and graduate students alike.

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

This book is open access under a CC-BY license. The multiple purposes of nature – livelihood for communities, revenues for states, commodities for companies, and biodiversity for conservationists – have turned environmental governance in Latin America into a highly contested arena. In such a resource-rich region, unequal power relations, conflicting priorities, and trade-offs among multiple goals have led to a myriad of contrasting initiatives that are reshaping social relations and rural territories. This edited collection addresses these tensions by unpacking environmental governance as a complex process of formulating and contesting values, procedures and practices shaping the access, control and use of natural resources. Contributors from various fields address the challenges, limitations, and possibilities for a more sustainable, equal, and fair development. In this book, environmental governance is seen as an overarching concept defining the dynamic and multi-layered repertoire of society-nature interactions, where images of nature and discourses on the use of natural resources are mediated by contextual processes at multiple scales.

This work examines the valley of the Urubamba River in terms of vertical zonation, Incan impact on the environment, plant use, the history of exploration and the notion of discovery, the idea of land reform, and cultural contact with the European world. Winding its path northward from the Andean Highlands to the Amazon, the valley has served as the stage of pre-Columbian civilizations and focal point of Spanish conquest in Peru. "Gade left behind not only a superb body of scholarly work, but a network of colleagues and students who remain indebted to his example. This book should serve as an inspiration for all scholars who wish to pursue the Sauerian, counter enlightenment or post development agendas of understanding and respecting particular places in all their historical and cultural complexity, including ambiguities and contradictions." -- The Geographical Review, American Geographical Society

Vacant urban land--the product of land market activity, the actions of private agents, and the policies of public agents--is an important challenge for policy makers. Vacant lots on the urban fringe and in central and interstitial areas have affected growth patterns in Latin America. Contributors to this book analyze the problems and opportunities related to vacant urban land in five cities: Buenos Aires, Argentina; Rio de Janeiro, Brazil; Quito, Ecuador; Lima, Perú; and San Salvador, El Salvador.
