Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Using the ecosystem concept as his starting point, the author examines the complex relationship between premodern armed forces and their environment at three levels: landscapes, living beings, and diseases. The study focuses on Europe's Meuse Region, well-known among historians of war as a battleground between France and Germany. By analyzing soldiers' long-term interactions with nature, this book engages with current debates about the ecological impact of the military, and provides new impetus for contemporary armed forces to make greater effort to reduce their environmental footprint.

For that purpose pollen analysis was a man who had lived more than 5,000 years ago with his performed on peat-bogs in the vicinity of the find and clothing and equipment almost intact. The discovery further afield to obtain precise data on the vegetation was not just deservedly a world-wide sensation but a cover and climate in the Neolithic. Pollen analysis was unique opportunity for the scientific community to in performed for a vertical transect extending from the vestigate the life and death of a human from such very timber line almost up to the nival zone.
