Making sense of new cultural economies, it is argued, needs consistent attention to the resonances of individual lives. Otherwise, a discussion of cultural economies remains suspended in a detached virtualism (Miller, 2000). The idea of the remaking of geographies and cultural economies remains, necessarily, a consistent search to make the subject dynamic in its resonance with the contemporary world. In recent debates concerning the reframing of the cultural economies of geography, there is an evidence of increasing acknowledgement of the overlooked importance of subjectivities within geographical explanation. This has often been difficult when trying to attend to the large scale apparent dynamics of change. The shift of geographies to focus upon cultural economies combines two profound threads that inform this chapter: the acknowledgement of the breadth and inclusivity of what economies are and the refusal mutually to isolate the cultural and the economic. Thus the economic becomes engaged and even framed in relation to the cultural, and vice versa. Such an appraisal makes more robust the limits of ‘either – or’ claims from these two grounding components of geographical thinking and its representation of the world. These themes are sustained in different ways across the chapters of this book. This chapter seeks to build a critical discourse concerning space, embodied practice and lay knowledge. It does this in order to address the mechanisms through which individuals are engaged in the processes of new cultural economies.

The fifth volume of The Oxford History of Historical Writing offers essays by leading scholars on the writing of history globally since 1945. Divided into two parts, part one selects and surveys theoretical and interdisciplinary approaches to history, and part two examines select national and regional historiographies throughout the world. It aims at once to provide an authoritative survey of the field and to provoke cross-cultural comparisons. This is chronologically the last of five volumes in a series that explores representations of the past across the globe from the beginning of writing to the present day.

Mexico is one of the most ecologically diverse nations on the planet, with landscapes that range from rainforests to deserts and from small villages to the continent’s largest metropolis. Yet historians are only beginning to understand how people’s use of the land, extraction of its resources, and attempts to conserve it have shaped both the landscape and its inhabitants. A Land Between Waters explores the relationship between the people and the environment in Mexico. It heralds the arrival of environmental history as a major area of study within the field of Mexican history. This volume brings together a dozen original works of environmental history by some of the foremost experts in Mexican environmental history from both the United States and Mexico. The contributions collected in this seminal volume explore a wide array of topics, from the era of independence to the present day. Together they examine how humans have used, abused, and attended to nature in Mexico over more than two hundred years. Written in clear, accessible prose, A Land Between Waters showcases the breadth of Mexican environmental history in a way that defines the key topics in the field and suggests avenues for subsequent work. Most importantly, it assesses the impacts of environmental changes that Mexico has faced in the past with an eye to informing national debates about the challenges that the nation will face in the future.

Despite international initiatives such as the Earth Summit in 1992 and ongoing efforts to implement the Kyoto Protocol, human activities continue to register a destructive toll on the planetary environment. At root, research on global environmental risk seeks new pathways for reversing unsustainable trends, curtailing ongoing destructive activities, and creating a life-sustaining planet. This book takes stock of the distinctive challenges posed by global environmental risks, the capacity of knowledge systems to identify and characterize such risks, and the competence of human society to manage the unprecedented complexity. Particular attention trains on engaging, in ways conducive to enhancing social learning and adaptation, the large uncertainties inherent in these risks. Various chapters enlist different scales of analysis to explore the manifestation and causes of global environmental risks in all the diversity of their regional expression. Throughout, the editors and contributors accord prominence to the vulnerability of people and places to environmental degradation. Understanding vulnerability is a neglected key to assessing the nature of the risks and determining strategies for altering trajectories of threat. Global risk futures, the editors argue, are not intractable, and are still amenable to a risk-analysis enterprise that is democratic in principle, humanistic in concept, and geared to the realities that pertain to the particular societies, locales, and regions that will ultimately bear the risk.

Human-induced environmental change is to be found throughout the world, but there are areas that scientists consider to be "critical regions" - regions that are particularly vulnerable to or suffering from environmental degradation. In this volume nine such "critical environmental regions" (Amazonia, the Aral Sea basin, the middle mountains of Nepal, Kenya's Ukambani region, the US Southern High Plains, the Mexico Basin, the North Sea, the Ordos Plateau of China, and the eastern Sundaland region of South-East Asia) are examined as case-studies. In chapter one the authors provide a detailed look into the concepts of environmental criticality and endangerment and propose formal definitions. The nine regional studies that follow in the subsequent chapters serve to translate the conceptual framework into the physical and social realities of each area. The case-studies make available an up-to-date synthesis of vast amounts of inaccessible data, and as such will be valuable to scholars and policy makers interested in specific areas of the world and others interested in regional comparisons. Anyone concerned with global environmental change, criticality, human-environment interactions, and how societies in different regions have responded to environmental degradation will find much that is new and important in this pioneering, innovative study.

Existe información que sugiere que la contienda contra el estrés, en las plantas cultivadas, empieza con el nacimiento mismo de la agricultura. Con el advenimiento de la Revolución Verde y la Post-revolución Verde, la contienda contra los efectos del estrés o contra el estrés mismo se intensificó. Los logros fueron impresionantes; no solo se produjeron volúmenes suficientes para abatir el hambre en el mundo, sino que se presumía que los alimentos, en algunos casos, eran biofortificados. No obstante, ya desde mediados de los 80s del siglo XX, se iba adquiriendo conciencia del costo tan elevado que tal bonanza traía consigo; contaminación del medio ambiente y producción de alimentos, que a medida que el estrés se reducía, tenían menos bioactivos útiles a la salud humana. Obviamente, bajo ese influjo adquirió relevancia el enfoque de producción orgánica, no solo porque se usa menos tecnología que pueda contaminar el ambiente, sino que además de esa forma, en la práctica se propiciaba, aunque sin el manejo pleno de algunas variables, una forma integral de estrés controlado. En consecuencia, los alimentos orgánicos tenían más bioactivos útiles a la salud del humano consumidor. Sin embargo, se han hecho evidentes varios inconvenientes de la producción orgánica; entre los más relevantes está el costo y la baja de rendimiento en comparación a la manera convencional más avanzada de agricultura. En este contexto brevemente esbozado, el objetivo de este libro es contribuir en la generación de una avenida hacia el vasto campo que ofrece la posibilidad de controlar el estrés tomando ventaja del comportamiento hormético de las plantas. Teniendo en cuenta que la curva que describe el comportamiento hormético se compone de dos zonas; una que ilustra una respuesta positiva, ascendente, de sobrevivencia llamada eustrés, y otra respuesta negativa, descendente en que la sobrevivencia mengua, denominada distrés. Así que el manejo del estrés en la agricultura habrá de consistir en controlar la utilización de estrés o imitadores para aprovechar el segmento más conveniente de la curva dependiendo del objetivo que se tenga con la planta cultivada. En este libro se presenta el potencial del manejo del estrés de la manera mencionada, con ejemplos de factores de estrés biológicos, químicos y físicos. Además, se aborda el empleo del uso de nanomateriales y las perspectivas para el manejo del estrés en la agricultura en siglo XXI.
