Forest Microbiology: Tree Diseases and Pests, Volume Three in the Forest Microbiology series, provides an overview of major disease agents of trees, including viruses, phytoplasma, bacteria, fungi, nematodes and major insect pests. With a strong emphasis on genetics, biochemistry, physiology, evolutionary biology and population dynamics of the organisms involved, this book provides a comprehensive understanding on the health of forests. Sections cover important pest threats such as bark beetles, emerald ash borer, coffee borers, leaf cutting ants, cocoa mirids, and more. This volume highlights a range of emerging diseases of forest trees in temperate and tropic regions as well as information on habitats. Forest trees play crucial roles not only for mitigating effects of the climate change but also for their considerable economic and ecological value. Forest trees are equally vital as an alternative bioenergy source and play important roles in pollution abatement and the maintenance of biodiversity. Timber and its associated products from forest trees contribute substantially to the revenue generation of many countries of the world.

This book is the result of over ten years of field research across Zambia. It covers the production and diverse uses of wood and non-wood forest products in different parts of Zambia. Although a short format, it is a multi-contributed work. It starts an overview of the forestry sector, and covers more specific areas like production, markets and trade of wood and non-wood products; the role of non-wood forest products in the livelihood of the local population, the contribution of the forestry sector to Zambia's overall economy and reviews of efforts to strategically utilize these resources for local economic, and sustainable, development.

An overview of the history of cocoa, the factors affecting its production and consumption as well as how the trade is conducted, various risks mitigated, and by whom.

Cocoa is a valuable commodity, and the cocoa trade involves many different parties from growers and exporters through dealers and factories to those trading futures and options and the banks they deal with. The International Cocoa Trade provides an authoritative and comprehensive review of the cocoa trade at the beginning of the twenty-first century, and the main factors that drive and affect that business.
The opening chapter of the third edition examines the history and origins of the international cocoa trade, and its recent developments. The agronomics of cocoa production are discussed in chapter two whilst chapter three deals with the environmental and practical factors affecting cocoa production. Chapters four, five and six cover issues around the export and trading of physical cocoa, including the actuals market, the physical contracts used and the futures and options markets. In chapter seven, the international consumption and stocks of cocoa are reviewed with chapter eight discussing the issue of quality assessment of cocoa beans for international trade. Finally, chapter nine focuses on the end product, examining the processing of cocoa beans and the manufacture of chocolate. Updated appendices provide copies of some of the most important documents used in the cocoa trade, including contracts, sale rules and world production statistics.
This comprehensively updated third edition of The International Cocoa Trade ensures its continued status as the standard reference for all those involved in the production consumption and international trading of cocoa.

Nearly three decades after the dawn of democracy, South Africa has remained a country of ‘two agricultures’. On the one hand we have a subsistence, primarily non-commercial, black farming segment. On the other hand, however, we have a predominantly commercial and white farming sector that is well-resourced and has access to domestic and international trade networks.

These disparities can be traced back to South Africa’s painful history where, for decades, black farmers were on the margins of government support and also experienced land dispossession and livestock plunder.

A Country of Two Agricultures focuses less on history and more on the present and the future, explaining why these disparities have persisted in the democratic era, and what it will take to overcome them. It aims to contribute to a better understanding of the variety of agricultural forces, taking into account both questions of domestic political economy and external factors, as well as to bring to light new risks and opportunities.

Wandile Sihlobo offers insights into the role of agriculture in the South African economy from an agricultural economy perspective, and provides political economy insights that are rooted in the experiences of farming communities on the ground and right through the value chain.

Beyond insights on the realities this book offers the government, the private sector, and anyone interested in the betterment of the South African economy, tools to grapple with this duality, and proposes a framework for bolstering the black farming segment for growth and competitiveness – and ultimately food security.

This book is the first coherent quantified assessment of the economy of the Roman Empire. George Maher argues inventively and rigorously for a much higher level of growth and prosperity than has hitherto been imagined, and also explains why, nonetheless, the Roman Empire did not achieve the transition which began in Georgian Britain. This book will have an enormous impact on Roman history and be required reading for all teachers and students in the field. It will also interest and provoke historians of the medieval and early modern periods into wondering why their economies failed to match the Roman level. Part of the problem in assessing the Roman economy is that we do not have much in the way of numerical data, but Roman historians, who rarely have much statistical expertise, have not always recognised the potential of the data we do have. Dr Maher's reassessment of the economy of the Roman Empire has to use the same data as everyone else, but he is able to draw strikingly novel conclusions in two ways: first, by more statistically sophisticated use of a few crucial datasets and, second, by correlating and drawing a coherent picture across the whole economy. On grain yields, firstly, instead of getting bogged down in details of individual cases, George Maher shows how there is a remarkably consistent pattern from which outliers can be excluded, showing yields were much higher than normally assumed. He then demonstrates that high yields are in fact necessary to explain the exceptional urbanization of the Empire. Urbanization at this level in turn, as George Maher shows, has implications for consumption and commerce. He takes this further to show how high levels of trade imply high levels of sophistication in economic practices and mentality. In one of his most methodologically novel chapters, George Maher develops a new and simpler way of assessing average life expectancy and argues for a life expectancy almost double the traditional view. This book, Dr George Maher's doctoral thesis, is the theoretical underpinning of his book Pugnare: Economic Success and Failure.

This unique book is the product of a south/north, east/west collaboration, involving some 90 contributors from 25 countries. It will be invaluable to all concerned with livestock keeping and poverty alleviation in developing countries, especially lecturers, students and those working with resource-poor livestock keepers. Livestock and Wealth Creation is about the role of livestock in developing countries and portrays how improved husbandry practices can affect the livelihoods of livestock keepers. It emphasises ways of improving small-scale enterprises and subsistence livestock-keeping. The burgeoning 'Livestock Revolution', which is already occurring in some developing countries and foreseen to become a wider phenomenon over the next 20 years, is also considered. A gigantic increase in demand for meat and milk is predicted, with consequent opportunities for resource-poor livestock keepers to contribute and move from subsistence to market-oriented production.
