Grassland ecosystems are deeply affected by human activities and need appropriate management to optimise trade-offs between ecosystem functions and services. Until now they have mainly been analysed as agro-ecosystems for animal production but this book looks beyond the role of grassland as a feeding ground, and evaluates other important processes such as carbon sequestration in soils, greenhouse gas regulation and biodiversity protection. This authoritative volume expertly highlights the need for an immediate balance between agriculture and ecological management for sustainability in the futu.
Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. - Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced - Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems - Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality
The Working Group M.O. (Interactions of soil minerals with organic components and microorganisms) (WGMO) of the International Soil Science Society (ISSS) was founded in 1990 at the 14th World Congress of Soil Science (Kyoto, Japan), with Professor P.M. Huang being the Chairman. Since then, the Working Group M.O. has served as a forum to bring together soil chemists, soil mineralogists, soil microbiologists, soil biochemists, soil physi cists and environmental, ecological, and health scientists. The objective of the Working Group M.O. is to promote research, teaching, and also the exchange of technology concerning the knowledge and the impact of the interactions between minerals-organics and ...
In the last two decades technological advances in isotope ratio mass spectrometry have been very rapid, opening up new possibilities for analysis of biological and environmental materials. The new instrumentation has facilitated faster analysis of samples via automated sample preparation and multi-isotope analysis of single samples, resulting in considerable cost savings, and enabling access to isotope analysis for many more researchers. These changes are reflected in the rapidly growing international literature on stable isotopes. While there have been some excellent books and review papers aimed at interpreting isotope signals in biology and environmental science, there have been fewer att...
L'agronomie a évolué au cours des trente dernières années, en élargissant ses échelles d'approche, en modernisant ses outils de travail et en renouvelant ses objets d'étude. S'appuyant sur une abondante bibliographie, l'ouvrage s'attache à montrer cette évolution en balayant l'ensemble du champ de connaissances que l'agronomie couvre aujourd'hui. L'ouvrage est destiné aux étudiants, aux professionnels et aux chercheurs non spécialistes de l'agronomie, intéressés par une vision panoramique et documentée des évolutions de la discipline. Il est accompagné d'un cédérom reproduisant une centaine d'articles de référence en agronomie.
This book uses a historical and modern lens to reimagine the role that Extension could potentially play in catalyzing reciprocal, co-learning relationships between Land-Grant Universities and their diverse local constituencies. The establishment of statewide extension systems was once seen as a way to ensure that Land-Grant Universities would be accessible and responsive to all of a state’s residents. Extension systems continue to offer a front-door to a major public university in almost every county of the United States, but they tend to be viewed primarily as a way to translate science or distribute information from the university to the public. This books argues for the importance of Ex...

La fertilité des sols est au carrefour des enjeux de sécurité alimentaire, de protection de l’environnement et de rentabilité économique de l’activité agricole. La notion de « fertilisation raisonnée », apparue dans les années 1970, doit de plus en plus être étendue à celle de « gestion durable des cycles biogéochimiques ». Cette évolution implique un élargissement des échelles spatiotemporelles considérées, une diversification des acteurs impliqués et un changement de nature des références à produire pour accompagner les décisions techniques. Dès lors, c’est tout le fonctionnement du système de recherche-développement-formation qui est questionné. Cet ouv...
En France, l’agriculture représente environ 20 % du total des émissions de gaz à effet de serre. Cet ouvrage propose dix actions ou pratiques agricoles permettant de les diminuer sans modification lourde des systèmes de production, ni réduction importante de la production. Pour chacune d’entre elles, le potentiel d’atténuation ainsi que les coûts ou gains associés, sont estimés à l’horizon 2030, en tonnes équivalent CO2 évitée pour le premier, en euros pour les seconds.
La composition, le fonctionnement et la santé des sols sont sous l’influence des propriétés physicochimiques des sols, des interactions entre plantes, microorganismes et faune du sol. Cet ouvrage présente les avancées récentes dans ces connaissances afin d’accompagner et de favoriser le développement des pratiques agroécologiques.
