Contrary to a generally held view that pearls are found by chance in oysters, almost all are now produced from farms. This book is a comprehensive treatment of all aspects of the biology of pearl oysters, their anatomy, reproduction, genetics, diseases, etc. It considers how they are farmed from spawning and culturing larvae in hatcheries to adults in the ocean; how various environmental factors, including pollution affect them; and how modern techniques are successfully producing large numbers of cultured pearls. This is the ultimate reference source on pearl oysters and the culture of pearls, written and edited by a number of scientists who are world experts in their fields. - Comprehensive treatment of pearl oyster biology and pearl culture - Written by the top world authorities - Highly illustrated and figured - Of practical relevance to a broad readership, from professional biologists to those involved in the practicalities and practice of pearl production
Provides guidance on the management of pearl oyster health and reviews pearl oyster mortalities and disease problems that will be useful for designing programmes aimed at reducing the risks from diseases. Part one consists of pearl oyster health; part two examines pearl oyster health management; part three contains a general review of pearl oyster mortalities and disease problems.
This book presents a comprehensive overview of research and projects regarding climate change adaptation in coastal areas, providing government and nongovernment bodies with a sound basis to promote climate change adaptation efforts.According to the 5th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), coastal zones are highly vulnerable to climate change, and climate-driven impacts may be further exacerbated by other human-induced pressures. Apart from sea-level rise, which poses a threat to both human well-being and property, extreme events such as cyclones and storm surges lead not only to significant damage to property and infrastructure, but also to salt water intrusion, groundwater salinisation, and intensified soil erosion, among many other problems. There are also numerous negative impacts on the natural environment and biodiversity, including damage to important wetlands and habitats that safeguard the overall ecological balance, and consequently the provision of ecosystem services and goods on which the livelihoods of millions of people depend. As such, there is a need for a better understanding of how climate change affects coastal areas and communities, and for the identification of processes, methods and tools that can help the countries and communities in coastal areas to adapt and become more resilient. It is against this background that this book has been produced. It includes papers written by scholars, social movements, practitioners and members of governmental agencies, pursuing research and/or executing climate change projects in coastal areas and working with coastal communities. Focusing on “managing climate change in coastal regions”, it showcases valuable lessons learned from research and field projects and presents best practices to foster climate change adaptation in coastal areas and communities, which can be implemented elsewhere.
Pearls are one of the oldest precious gemstones. They have been revered through history and the best reserved to adorn royalty and their favourites. Now, with the arrival of freshwater pearls, they are available to suit every pocket and every style, from the classic to the most creative. It includes a guide to the types of pearl and to the farming process. It gives advice on buying pearls; what to look for and what to avoid and gives instruction on working with pearls, including drilling, setting and knotting. Finally, there is information on South Sea, Tahitian, Akoya, freshwater and natural pearls. This practical book celebrates their exquisite beauty and enduring elegance.

Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.
