La sostenibilidad, cualidad de lo sostenible, hace referencia a un proceso que puede alargarse en el tiempo. Cuando este proceso lo referimos a cuestiones socio-ecológicas, comprobamos cómo, desde hace ya largo tiempo, no son pocas las voces acreditadas que han puesto sobre aviso del progresivo deterioro ecológico y sus consecuencias perjudiciales para la vida humana. Nuestra obra parte de estas negatividades para repensar la idea de sostenibilidad en sus justos términos, y así dar cabida a una variedad de aportaciones que ayuden a restituimos dentro de los límites ecosistémicos.
The effects of light pollution on flora, fauna -including humans and their widely varying night-time activities- are often subtle and need extensive field studies to be quantified in a sensible manner. Some of the highlights were: The presentation of the 1st world atlas of artificial night sky brightness (Cinzano et al.); the article by the International Darksky Association on their world-wide efforts to curb light pollution (Alvarez del Castillo et al.); the laws controlling light pollution implemented in Spain (Diaz et al.) and Chile (Sanhueza et al.), an overview of the work on radio frequency protection of sites (Cohen et al.) and the excellent introduction to the topic from the Chilean point of view (Daud). Related topics in the book are light pollution education, aircraft contrails, space advertising (with an added document provided by the relevant UN commission), and an experiment on involving the population of an entire country in measuring sky brightness, by using the internet and the media. The text is aimed at professionals from a wide range of disciplines related to lighting and its effects on the night-time environment in the broadest sense of the word. Lay persons interested in this emerging multi-disciplinary field can also find much of interest in this book.
The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly -- Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap. This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region. Tropical Conservation: Perspectives on Local and Global Priorities drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.
On 23 September 2021, the Food Systems Summit convened by the Secretary-General of the United Nations, António Guterres, was held. Latin America and the Caribbean played an essential role in this event. The official proposals and recommendations presented at the Summit are part of the official reports of the national dialogues and the speeches of their official representatives. In this publication, we reproduce the transcripts of these 23 speeches. This publication is an invitation to those who want to learn about Latin America and the Caribbean proposals at the Summit.
Nuestra segunda vida en el mundo digital, la comida genéticamente modificada, las prótesis de nueva generación y las tecnologías reproductivas son aspectos ya familiares de la condición posthumana. Ya que se han borrado las fronteras entre aquello que es humano y aquello que no lo es, poniendo en evidencia la base no natural del ser humano actual. Desde el punto de vista de la Filosofía y la Teoría Política, urge actualizar las definiciones de identidad y los fenómenos sociales a raíz de este salto. Con un simple análisis se verá que después de haber constatado el fin del Humanismo, es preciso ver en esta transformación las malas intenciones de una colonización de la vida por parte de los mercados y su lógica del beneficio. Es preciso, pues, adecuar la teoría a los cambios en curso, sin añoranzas por una humanidad ahora perdida y cogiendo las oportunidades ofrecidas por las formas de Neohumanismo que nacen de los movimientos medio ambientales y de los Estudios de Género y Postcoloniales.
