The strange death of three young children in a small coastal village in far away Papua New Guinea in March 1972 did not rate a mention in the territory’s annual report that year to its Australian governors—let alone make a ripple in international ponds. Yet, it was an event of incredible proportions. It marked the end of a chain of knowledge that extended back more than 45,000 years; it heralded the beginning of an era of immense, baffling phenomena and disasters around the world; and it marked the rise of a deadly toxin from the seabed that would spread from country to country. The book works back in time to discover the origin of the toxin’s host, traces its emergence and bizarre spread from country to country with resulting deaths, and projects into the future the likely, unsettling to horrific, consequences for the world’s food security, already set irreversibly in motion. It is a story that encompasses much of the globe, from the Pacific islands to Asia—Brunei Darussalam, Indonesia, Japan, Malaysia and the Philippines—to the Middle East—Persian Gulf and Red Sea, and the Egypt of the Pharaohs—to the Pacific and Atlantic coasts of the Americas, and to Australia and Antarctica. It is a detective story too, about who or what killed the three children, taking us in helicopters, light planes, speedboats and a naval patrol vessel, and on underwater explorations. It is a romance spanning a period from the tail end of the Palaeolithic era, pausing for a less ancient exodus, that of the Jews from Egypt, and for Cleopatra’s—incredibly expensive as we will see—dinner with Marc Antony, and leap-frogging through events over the following two millennia via connections with Spanish kings, Napoleon Bonaparte, and the most famous pair to play the part of Cleopatra and Marc Antony in modern times: Elizabeth Taylor and Richard Burton. Finally, it is the story of a young scientist sent unknowingly as a spy into Papua New Guinea shortly before its independence. How did he find himself enmeshed in the threads of this strange puzzle and what did he discover?

In the arid lands of Kenya, the social structure system associated with traditional pastoralism has evolved useful mechanisms for achieving sustainable resource utilization within fragile dryland environments. The sustainability of traditional pastoralism in Kenya is no longer feasible due to the increasing pressure on a shrinking resource base. This uncertainty with the sustainability of this traditional life style, calls for a radical shift in thinking from traditional to commercial pastoralism. Commercial pastoralism allows for the emergence of dynamic pastoralism which adapts quickly to technological changes and evolving market conditions in a fast changing pastoral environment. Whereas this futuristic form of pastoralism must recognize pastoral communities as legal entities and accord them the rights of control and disposal or transfer, it should also bestow the rights of access and use on individual pastoralists. The individualization of the right of land disposal or transfer in non-enlightened pastoral communities has led to the emergence of destitution and poverty in pastoral areas of Kenya. This book publication provides valuable information on emerging issues and options on pastoral land management in Kenya. It is based on a three year study on Land Tenure and Natural Resource Management in the Arid Lands of Kenya. It also does provide the requisite information for the formulation of a policy and legal framework on sustainable pastoral land management in Kenya.

Kenya covers a total land area of 582,646 km2. This land area is classified in terms of agricultural potential as: 12.7% of medium to high potential for agricultural production; 11.5% of arable land, subject to periodic droughts; 70.7% of drylands; and 5.6% of non-agricultural land. High population densities are more prevalent in areas of high agricultural potential than those of low potential (drylands). Most of Kenya's population (approx. 80%) lives in rural areas and therefore depends on agriculture and livestock for food and income.This book reviews sustainable technological options for land and water management and that are appropriate to soil and moisture conservation in drylands areas of Kenya. Of significant importance are: Environment and Resource Conservation in Semi-Arid Kenya; Dryland agriculture and conservation technologies in Kenya; Sustainable Soil Management Technologies for Effective Erosion Control in Semi-Arid Kenya; Development of Sustainable Conservation Techniques for Dryland Agriculture in Semi-arid Kenya; Agroforestry for Environmental Conservation in Dryland Environments of Kenya; Carbon Sequestration in Dryland Soils; Integrated Watershed Resource Management in Semi-arid Kenya; Runoff Water Management Systems for Dryland Agriculture in Semi-Arid Kenya; Land and Water Management for Poverty Alleviation: Experiences from Iiuni Watershed, Machakos County, Kenya; and Participatory Role of Communities in Sustainable Development and Management of Resources in semi - arid environments of Kenya?

Whoever wishes to investigate medicine properly, should proceed thus: in the first place to consider the seasons of the year, and what effects each of them produces for they are not at all alike, but differ much from themselves in regard to their changes. Then the winds, the hot and the cold, especially such as are common to all countries, and then such as are peculiar to each locality. We must also consider the qualities of the waters, for as they differ from one another in taste and weight, so also do they differ much in their qualities.

It is estimated that 4-8 million people in the United States suffer with Fibromyalgia. Another one million also have Chronic Fatigue Syndrome. Some statistics state that Chronic Fatigue Syndrome and Fibromyalgia may directly affect 5% of the world's population. I am one of the individuals in this growing epidemic. In 1997, after a chaotic year of intense medical and psychological testing, I was diagnosed with Chronic Fatigue Syndrome and Fibromyalgia. I spent much of the last ten years in deep denial feeling alone, confused, frustrated, and angry. It has taken me a great deal of soul searching, but I believe that today I am a better, more centered person because of my experiences. I've never been someone who dictates advice, so my book provides worksheets you can develop to tailor your personal responses to symptoms and crises. It is the good, the bad, and the ugly of my personal journey that I share with you, my fellow Fibromites. My hope is simple, that you will find solace and renewed hope in my words.What People Are Saying About Strategies "This book is a passionate, intense account of one person's conquest over suffering. As a psychologist working with chronic pain sufferers, I can endorse Ms. Brady's philosophy, approach and tools." -Bob Rich, PhD, author Cancer: A Personal Challenge Author info at http://tami-brady.com Another great self-help book from Loving Healing Press
