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.

Written by leading experts in the field, HACCP in the meat industry provides an authoritative guide to making HACCP systems work effectively.
This book examines the HACCP in the meat industry across the supply chain, from rearing through to primary and secondary processing.

Diamonds are almost completely useless but prized above all other gems. Historically they have attracted crimes of passion and awful cold-blooded efficiency, have bedazzled the greatest filmstars and the most opulent courts, and provided the incentive for adventure, destruction and greed on a monumental scale. No one company is more identified with diamonds than the South African based De Beers.

Until the collapse of the Iron Curtain they controlled the diamond market. After the collapse, they still controlled it – once they had bought up most of the diamonds emerging from the former Soviet Union. They are secretive, discreet and very, very powerful. A strike in Northern Canada could hardly seem to trouble them. Except that it prefigured a diamond rush in a territory over which they had no influence by prospectors they did not own. And the strike promised enormous riches.

Here is the true story of the strike that upset the diamond kings, and with it the history of the world’s most acclaimed diamonds, the process by which they are cut, fashioned, smuggled and stolen, the legends and superstitions that are attached to them, the characters who comprise the great diamond prospectors and, above all, of the shadowy hand of De Beers for whom diamonds are forever.

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.

In 1996, the Argentine government authorized the use of genetically modified (GM), herbicide-resistance soybean seeds. By the mid-2000s, GM soybeans were cultivated on more than half of the arable land in Argentina and represented one-fourth of the country's exports. While this agricultural boom has benefitted agribusiness companies and fed tax revenues, it also has a dark side: it has accelerated the deforestation of native forests, prompted the eviction of indigenous and peasant families, and spurred episodes of contamination. In Soybeans and Power, Pablo Lapegna investigates the ways in which rural populations have coped with GM soybean expansion in Argentina. Based on over a decade of ethnographic research, Lapegna reveals that many communities initially resisted, yet ultimately adapted to the new agricultural technologies forced upon them by public officials. However, rather than painting the decline of the protests in an exclusively negative light, Lapegna argues that the farmers played an active role in their own demobilization, switching to tactics of negotiation and accommodation in order to maneuver the situation to their advantage. Lapegna offers a rare, on the ground glimpse into the life cycle of a social movement, from mobilization and protest to demobilization and resigned acceptance. Through the case study of Argentina, a major player in the use and export of GM crops, Soybeans and Power gives voice to the communities most adversely affected by GM technology, as well as the strategies that they have enacted in order to survive.
