The Southern Africa region has experienced more than its fair share of problems in recent years. Just when it seemed that the hardships wrought by the devastating cycle of droughts and floods of 2000 to 2002 were a thing of the past, other problems emerged. At one level, there have been the weak and often erratic governance mechanisms and political crises in some countries of the region, leading to severe disruptions in agricultural production to the point that supplies and markets have virtually disappeared. At another level, socio-cultural rigidities have often militated against the adoption of efficient farming practices, resulting in sub-optimal choices that lock smallholders into a low equilibrium trap. In the face of the disappearing supplies and missing markets, these have engendered hyper-inflationary trends of a magnitude unknown anywhere else in the world. But in the midst of all this apparent dreariness, cases are emerging from which immense lessons can be drawn. This book assembles a collection of research papers based on studies completed in 2008 and 2009 in Southern Africa that examine various dimensions of the institutional constraints small farmers are facing in the region and how they are going about dealing with them. The papers draw from these diverse and polar experiences and present some theoretical and practical insights that should form the basis for more in-depth, country-level, sector-specific analyses, focusing mainly on citrus, horticultures, cotton and livestock. The thematic issues of income inequality, land reform, natural resource management and value chain governance and chain choice, are covered in this book and are expected to be of interest for a wide constituency, including researchers, development practitioners, rural animators, and policy makers.

For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has moved from the aim to cover the requirements of the animal to explaining and predicting the responses of the animals to diets (e.g., productivity and efficiency, impact on quality of products, environmental aspects, health and well-being). In this book several chapters illustrate that through empirical models, meta-analysis is an efficient tool to synthesize information gathered over recent decades. In addition, compared with other books on modelling farm animal nutrition, two new aspects received particular attention: expanding knowledge of the individual animal to understanding the functioning and management of herds, and the consideration of the environmental impact of animal production. This book is a valuable source of information for researchers, nutritionists, advisors, and graduate students who want to have up-to-date and concise information on mathematical modelling applied to farm animals.

This book is the first of its kind to use Austrian subjectivism to analyze issues in economic development. Unlike scholars in mainstream neoclassical economics who explain economic development by quantitative growth models, this book attempts to understand economic progress in human agency perspective. In this approach, human agency is placed at the centre of economic analysis. This book begins with a review of the theories of economic development in the history of Austrian economics, with the intention of extending the contributions of major Austrian economists to development economics. After pointing out the weaknesses in the orthodox neoclassical approach to economic growth, the book then puts forward a subjectivist methodology which integrates the contributions of Max Weber, Alfred Schutz and Austrian Economists to interpret economic phenomena and policies. This chapter also serves as a methodological foundation for arguments elaborated in subsequent chapters. The rest of the book discusses important issues in economic development, namely, entrepreneurial process, national capabilities, innovation, trade, government, transition and catching up strategies for firms in latecomer economies. The book ends with concluding remarks and a proposal for a new research agenda in economic development. This book is well written, free from mathematics and is highly readable. It adds new insights not only in economics, but also in management, politics and social sciences. It will be useful to scholars, policy makers and students in economic development, entrepreneurship, theory of the firm, management of innovation, government policy, economic sociology, Austrian and evolutionary economics.

NorFor is a semi-mechanistic feed evaluation system for cattle, which is used by advisors in Denmark, Iceland, Norway and Sweden. This book describes in detail the system and it covers five main sections. The first is concerned with information on feed characteristics, feed analysis and feed digestion methods. The second section describes the digestion and metabolism in the gastrointestinal tract and the supply and requirement of energy and metabolizable amino acids. The third section considers the prediction of feed intake and physical structure of the diet. The fourth section focuses on model evaluation and the final section provides information on the IT solutions and feed ration formulation by a non-linear economical optimization procedure. This book will be of significant interest to researchers, students and advisors of cattle nutrition and feed evaluation.

Game meat is consumed world-wide. In most regions, it contributes only a small part to the overall meat and food supply, but for reasons of animal welfare and sustainability it is sometimes considered an alternative to meat from farmed animals. Despite differences in game species, ante mortem conditions (free-range or fenced; wild or semi-domesticated), hunting or harvesting procedures and further handling of the carcass, there are common requirements as regards meat safety and quality. Whereas meat hygiene and safety have been an issue in game meat for export/import for a long time, primary production, domestic supply and direct supply to the consumer have recently been addressed by legislation and these sectors still present unresolved questions and challenges. This book combines 24 contributions presenting the view of experts in game meat hygiene and quality. They address four main topics: i.e. 'hygiene and microbiology', 'epidemiology', 'risk assessment and management' and 'muscle biology and meat quality'. In addition to contributions on this topic by authors from eight European countries, a South African perspective is provided, thus representing the standpoint of a major game meat exporter. This volume is the first in a series on safety and quality assurance along the game meat chain, following a 'from forest to fork' approach and is targeted at scientists in academia and industry, graduate students as well as at governmental officials in veterinary public health and food safety.

Proposant une analyse passionnante de l'Évolution, le livre de Richard Dawkins compare l'Évolution à un fleuve où seuls survivent les gènes les plus aptes. Cette démonstration serrée et rigoureuse, qui se situe dans la droite ligne de la pensée darwinienne, se nourrit de nombreuses anecdotes sur le monde des abeilles et des orchidées, sur la "finalité" de l'oeil, sur les ancêtres de l'Homme, etc. Un ouvrage d'introduction limpide à la théorie darwinienne qui sait allier une remarquable qualité pédagogique à une rigueur sans faille
