Book Description
In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Book Description
This volume contains the lectures and seminars given at the NATO Advanced Study Institute on “Sensor Systems for Biological Threads: The Algal Toxins Case”, held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.

Book Description
The current volume, "Medicinal and Aromatic Plants of the Middle-East" brings together chapters on selected, unique medicinal plants of this region, known to man since biblical times. Written by leading researchers and scientists, this volume covers both domesticated crops and wild plants with great potential for cultivation. Some of these plants are well-known medicinally, such as opium poppy and khat, while others such as apharsemon and citron have both ritual and medicinal uses. All have specific and valuable uses in modern society. As such, it is an important contribution to the growing field of medicinal and aromatic plants. This volume is intended to bring the latest research to the attention of the broad range of botanists, ethnopharmacists, biochemists, plant and animal physiologists and others who will benefit from the information gathered therein. Plants know no political boundaries, and bringing specific folklore to general medical awareness can only be for the benefit of all.

Book Description
Today marks the release of the controversial book "Commodities: Switzerland's Most Dangerous Business". The fact-filled and groundbreaking analysis of the industry, as powerful as it is unknown, shows why resource-rich developing countries remain poor while Switzerland-based commodity companies rake in profits in the billions. And it illustrates the gray areas of a business model whose risks are becoming increasingly apparent. Unnoticed by the public and politicians, Switzerland has become the world's most important commodities hub. Trade in oil, gas, coal, metals and agricultural products - particularly via deals made in Geneva and Zug - has grown by an incredible 1,500 percent since 1998, according to BD investigations. The result: Seven of the twelve corporations with the highest turnover in Switzerland trade in, and/or mine, commodities. Switzerland has become a global commodity hub thanks to its mix of tax privileges, a strong financial sector, weak regulation and lax embargo policy. The Swiss commodities business is dangerous for developing countries that are blessed with natural resources but that suffer from weak governance. The business is life-threatening for all those who must live amid the filth and toxins of the mines and facilities. The extensive misery of entire countries and the fairytale wealth of a few Swiss top traders are causally related. The book "Commodities: Switzerland's Most Dangerous Business" shows how. The richly-illustrated reference work offers a portrait of the key firms and people behind the discreet deals, provides insight into the social and ecological consequences for the producing countries, analyzes the practices and repercussions of tax avoidance and speculation, and offers proposals for achieving more justice in a multi-billion-dollar business that affects everyone.

Book Description
This volume in the series is devoted to Africa, a continent that possesses a vast treasure of medicinal plants and has produced some exclusive materials for the world market. This volume is expected to strengthen the medicinal plant sector in African countries by making comprehensive information on medicinal and aromatic plants available to policy-makers and entrepreneurs. It can be used to frame effective policies and create an environment conducive to the growth of the plant-based medicine industry, bringing economic benefit to African nations. It will help health organizations to improve the health of their people by using their own resources and a less expensive system of medicine, which is accepted by African society. It could also lead scientific communities to increase R&D activities in the field.
