Book excerpt: La presence de produits phytosanitaires dans les eaux de surface a des concentrations parfois superieures aux seuils imposes par la communaute europeenne incite a developper des outils de modelisation permettant de juger du degre de contamination d'un bassin versant, et de proposer des solutions pertinentes. Compte tenu de la complexite et de la forte non linearite des phenomenes auxquels sont soumis les produits phytosanitaires, il est souhaitable de decoupler l'etude de ces phenomenes de celle du transfert de l'eau, et de s'attacher dans un premier temps aux composantes rapides de l'ecoulement. Pour un bassin rural et bocager comme celui sur lequel a porte le travail, cela implique de representer explicitement le role du reseau anthropique de fosses, talus et routes qui sillonne le bassin, et de rendre compte des specificites des sols laboures. Le modele a base physique distribue topog, dont le maillage permet la representation implicite des zones convergentes et divergentes, a ete adapte en ce sens. L'application de modeles adaptes a permis l'acquisition d'ordres de grandeur theoriques sur le role des fosses dans une pente et sur les temps de transfert dans le reseau anthropique. Ces estimations ont servi de base a la representation choisie pour le role des elements du reseau anthropique sur les ecoulements, et a la programmation qui a suivi. Le modele obtenu a ete applique au bassin versant de naizin (morbihan). L'analyse de terrain a permis de caracteriser le bassin et son reseau anthropique, par des criteres tant topographiques que topologiques (aire drainee notamment). Il n'a toutefois pas ete possible d'etablir une typologie fonctionnelle des differents types d'elements du reseau anthropique au seul vu de ces criteres. L'application du module hydrologique a montre la capacite du modele a representer une grande gamme de processus. Le calage aboutit a des hydrogrammes satisfaisants, mais ne permet pas de trancher quant aux processus dominant les ecoulements sur le bassin d'application. Ceci vient pour partie du fait que les donnees disponibles, bien que nombreuses et variees, ne sont pas adaptees a la problematique. Plus generalement, il semble essentiel de caracteriser le comportement des composants du systeme qu'est un bassin versant, et notamment celui des sols, a une echelle compatible avec la modelisation.

Book excerpt: This open access book not only describes the challenges of climate disruption, but also presents solutions. The challenges described include air pollution, climate change, extreme weather, and related health impacts that range from heat stress, vector-borne diseases, food and water insecurity and chronic diseases to malnutrition and mental well-being. The influence of humans on climate change has been established through extensive published evidence and reports. However, the connections between climate change, the health of the planet and the impact on human health have not received the same level of attention. Therefore, the global focus on the public health impacts of climate change is a relatively recent area of interest. This focus is timely since scientists have concluded that changes in climate have led to new weather extremes such as floods, storms, heat waves, droughts and fires, in turn leading to more than 600,000 deaths and the displacement of nearly 4 billion people in the last 20 years. Previous work on the health impacts of climate change was limited mostly to epidemiologic approaches and outcomes and focused less on multidisciplinary, multi-faceted collaborations between physical scientists, public health researchers and policy makers. Further, there was little attention paid to faith-based and ethical approaches to the problem. The solutions and actions we explore in this book engage diverse sectors of civil society, faith leadership, and political leadership, all oriented by ethics, advocacy, and policy with a special focus on poor and vulnerable populations. The book highlights areas we think will resonate broadly with the public, faith leaders, researchers and students across disciplines including the humanities, and policy makers.

It is the continent's third largest river basin, traversing nine countries -Benin, Burkina Faso, Cameroon, Chad, C©þte d'Ivoire, Guinea, Mali, Niger, and Nigeria. The River embodies both these nations' livelihoods and their geopolitics. It is not simply water but rather an origin of identity, a route for migration and commerce, a source of conflict, and a catalyst for cooperation. Cooperation among decision-makers and users is crucial to address the threats to water resources. The Niger.

This book was released on 2015-06-17 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Book excerpt: The authors preceive a trend in the study and practice of groundwater hydrology. They see a science that is emerging from its geological roots and its early hydraulic applications into a full-fledged environmental science. They see a science that is becoming more interdisciplinary in nature and of greater importance in the affairs of man. This book is their response, and they have provided a text that is suited to the study of groundwater during this period of emergence.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.
