Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the impact computerization has had on contemporary science and explains the origins, technical nature and epistemological consequences of the current decisive interplay between technology and science: an intertwining of formalism, computation, data acquisition, data and visualization and how these factors have led to the spread of simulation models since the 1950s. Using historical, comparative and interpretative case studies from a range of disciplines, with a particular emphasis on the case of plant studies, the author shows how and why computers, data treatment devices and programming languages have occasioned a gradual but irresistible and massive shift from mathematical models to computer simulations.

Book excerpt: The STICS crop model has been developed since 1996 at INRA in collaboration with other research and technical institutes. The model syntheses, illustrates and concretizes an important part of the French agronomic knowledge as a point of view on the field and cropping systems working. The formalisations of the STICS crop model presented in this book can be considered as references used in the framework of crop sciences. The book arrangement relies on the way the model designs the crop-soil system functioning, each chapter being devoted to a set of important functions such as growth initiation, yield onset, water uptake, transformation of organic matter etc. One chapter deals with the cropping system and long term simulations and the final chapter is about the involvement of the user in terms of option choices and parameterization. If this book is mainly intended for scientists who use the STICS model, it can also be useful for agronomists, crop modellers, students and technicians looking for elementary formalizations of the crop-soil system functioning.

Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models are being used more and more widely to study complex dynamic systems (global weather, ecological systems, hydrological systems, nuclear reactors etc. including the specific subject of this book, crop-soil systems). The models are important aids in understanding, predicting and managing these systems. Such models are complex and imperfect. One fundamental research direction is to seek a better understanding of how these systems function, and to propose mathematical expressions embodying that understanding. However, this is not sufficient. It is also essential to have tools (often mathematical and statistical methods) to aid in developing, improving and using the models built from those equations. The book is specifically concerned with the application of methods to crop models, but much of the material is also applicable to dynamic system models in other fields. The goal of this book is to fill that gap. * State-of-the-art methods explained simply and illustrated specifically for crop models* Parameter estimation – applying statistical methods to the complex case of crop models, including Bayesian methods * Includes model evaluation, understanding and estimating prediction error* Offers a unique data assimilation by using the Kalman filter and beyond

Available in PDF, EPUB and Kindle. Book excerpt: Good management of water resources - universally identified as a key aspect of poverty reduction, agriculture and food security - has proven, in practice, as difficult to achieve as it is eagerly sought. This book, edited and authored by leading authorities on water resource management, examines the recent changes in governance, institutions, economics and policies of water, covering developing, transitional and developed countries, with special emphasis on southern African case studies. The book examines how water policies, institutions and governance have shifted in recent years from supply-driven, quantitative, centrally controlled management to more demand-sensitive, decentralized, participatory approaches. Such a move often also implies cost recovery principles, resource allocation among competing sectors, and privatization. The case studies demonstrate that the new policies and legal frameworks have been difficult to implement and often fall short of initial expectations. Using an accessible multidisciplinary approach that integrates economics, sociology, geography and policy analysis, the book untangles the issues and presents best practices for policy- and decision-makers, governments and regulators, NGOs and user groups, service providers, and researchers. The overall aim is to show how good water governance structures can be developed and implemented for the benefit of all.

Available in PDF, EPUB and Kindle. Book excerpt: This publication comprises material on recent studies on quality management in agri-food chains. Due to several food crisis’s (e.g. BSE, Foot-and-Mouth disease) and growing demands for food quality and safety, quality management systems and quality assurance schemes have been widely adopted in different countries in recent years. Scientific knowledge about the features, the acceptance and the effectiveness and efficiency of these newly introduced quality management initiatives, has remained scarce until now. The material by experts in the field, focuses on the evaluation of quality management systems and quality assurance schemes. The main issues are the costs and benefits of quality management given the influence of the public sector and consumers' expectations about food quality and safety. Not only are benchmarking and harmonisation methods examined with regard to their impact on the effectiveness of quality assurance schemes, but, also the role of trust, cooperation and integration for efficient quality management is discussed. Different economic theories such as microeconomics, organization and marketing theory as well as advanced statistical methods are applied. Concepts are discussed from the various points of view of industrialised, export-oriented and developing countries throughout the book. The information in this book give a comprehensive review of quality management concepts in food chains and highlight future research directions from a global perspective. This book is of interest to all those who concern themselves with the topic, be it in academia or in the professional sector.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La modélisation dans le domaine de l'agro-écologie est importante car elle permet de mieux comprendre les interactions entre l'environnement et les activités humaines. Des travaux basés sur la simulation ont été développés depuis des années. Cependant, non seulement ces outils restent difficiles à utiliser par les utilisateurs non experts, mais aussi le coût des modèles rend leur utilisation difficile à case de la complexité élevée en cas d'application réelle. Nous proposons une approche qui consiste à représenter le système étudié dans un formalisme de système à événements discrets qui est bien adapté quand la dynamique du système est liée à des interactions entre les entités concernés. Ceci permet de profiter l'efficacité du model-checking pour étudier le comportement du système modélisé et d'utiliser la synthèse de contrôleur pour générer automatiquement des stratégies optimales. Nous présentons deux contributions dans cette thèse. La première contribution concerne le projet EcoMata. Cette modélisation qualitative en automates temporisés pour un réseau trophique marin de type proie-prédateur permet d'analyser l'écosystème à l'aide de model-checking sans avoir à faire des simulations. Des scénarios de requête prédéfinis ont été développés dans un langage naturel pour que les utilisateurs non expert puissent faire des requêtes sur les réseaux trophiques sans avoir des connaissances sur la langage TCTL. Nous avons amélioré la génération automatique d'automates temporisés à partir d'une description des équation Lotka-Votera. Nous avons aussi proposé une approche de synthèse de contrôleur pour générer automatiquement des stratégies optimales de gestion de pêche. Le prototype logiciel EcoMata implémente l'ensemble des propositions incluant la recherche de stratégies optimales. Dans la seconde contribution, nous proposons une modélisation hybride en automates temporisés d'une exploitation de pâturage. Cette modélisation hybride combine un modèle numérique de la croissance d'herbe et un modèle qualitatif des activités de pâturage. Une structure hiérarchique organise les modèles dans quatre couches: la couche biologique, la couche activité, la couche décisionnelle et la couche d'horloge. Nous proposons quatre méthodes pour générer des stratégies optimales des activités de pâturage. La première méthode est appliquée à la recherche de stratégies optimales de la mise au pâturage. Trois méthodes sont dédiées à la recherche de stratégies optimales de la fertilisation. Une d'entre elles utilise la synthèse de contrôleur alors que les deux autres combinent la synthèse de contrôleur et l'apprentissage supervisé pour générer des stratégies génériques par type d'exploitation. Un prototype logiciel PaturMata a été développé implémentant cette modélisation, permettant aux utilisateurs de simuler des scénarios de pâturage et rechercher des stratégies optimales de mise au pâturage.
