Book Synopsis Utilisation du sol et diversité biologique dans les Alpes by : Jürg Stöcklin
Download or read book Utilisation du sol et diversité biologique dans les Alpes written by Jürg Stöcklin and published by vdf Hochschulverlag AG. This book was released on 2007 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le passage à une exploitation intensive, l’abandon de surfaces abruptes et isolées ainsi que l’extension du milieu urbain ont provoqué dans les Alpes une diminution considérable de la qualité du paysage et de la diversité biologique au cours des dernières décennies. Ces transformations ont été analysées en détail dans le cadre du Programme national de recherche PNR 48 "Paysages et habitats de l’arc alpin". La présente synthèse thématique s’intéresse au rôle de l’agriculture et de la sylviculture, qui exerce l’influence directe la plus forte sur les paysages et les écosystèmes. Refusé par une bonne partie de la population, le recul persistant de la qualité du paysage et de la diversité biologique contredit en outre les engagements nationaux et internationaux de la Suisse. Les auteurs montrent que ce recul peut être endigué par une indemnisation systématique et ciblée des prestations agricoles susceptibles de valoriser le paysage et de promouvoir la biodiversité, sans qu’il faille mobiliser des moyens supplémentaires en faveur de la politique agricole. Les modifications proposées du système de paiement direct laissent espérer non seulement une amélioration de la qualité du paysage et un accroissement de la diversité biologique, et donc un véritable renversement de tendance, mais aussi une amélioration de la situation économique des agriculteurs de montagne.

Book Synopsis Seaweeds and their Role in Globally Changing Environments by : Alvaro Israel
Download or read book Seaweeds and their Role in Globally Changing Environments written by Alvaro Israel and published by Springer Science & Business Media. This book was released on 2010-06-18 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming is accelerating faster than the ability for natural repair, and environmental stresses are damaging ecosystems, all affecting physical and biological systems on Earth. A new Nasa-led study shows that human activity has caused climate changes resulting in permafrost thawing, acid rain, and lower productivity in lakes as well as increased emissions of greenhouse gases, including CO2, N20, CH4, CF3, and CFC. Marine plants play a vital role in maintaining the balance of marine environments, while serving as a source of food for humankind and important chemical compounds. Microalgae and seaweed have enormous potential for reducing global warming and climate change. During photosynthesis algae grow, draw CO2 from the atmosphere, release oxygen, and produce solar biofuel. Experts in the life of marine plant ecosystems in globally changing environments contributed chapters to this book. The target readers are phycologists, ecologists, atmospheric scholars, conservationists, environmentalists, and ecologically aware laymen.

Book Synopsis Grass Productivity: An Introduction to Rational Grazing by : Dr. Robert C. Worstell
Download or read book Grass Productivity: An Introduction to Rational Grazing written by Dr. Robert C. Worstell and published by Lulu.com. This book was released on 2015-01-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: "What is grazing?" The answer is generally as follows: "Causing grass to be eaten by an animal." That is correct! But here is another answer which, to my mind, is more realistic: "Causing the grass and the animal to meet." Since this book is almost exclusively concerned with grazing by cattle, I propose the following definition to the reader, requesting him to allow it to become well impressed upon his mind: Grazing is the meeting of cow and grass. It is by satisfying as far as possible the demands of both parties that we will arrive at a rational grazing, which will provide us with maximum productivity on the part of the grass while at the same time allowing the cow to give optimum performance.
