Book Synopsis Cover Crops for Sustainable Farming by : Eric Justes
Download or read book Cover Crops for Sustainable Farming written by Eric Justes and published by Springer. This book was released on 2017-05-29 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, based on a literature review and simulations, shows the efficiency of cover crops at catching nitrate in most agriculture situations. It also analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the drainage water. This study allows quantifying the efficiency of cover crops at catching nitrate and optimizing their implantation conditions over a large range of French pedoclimatic conditions. The presence of high nitrate levels in surface and ground waters, due to excessive nitrogen fertilization and natural production of nitrate by soil organic matter mineralization, is a double challenge for public health and environment protection.

Download or read book La Caraïbe, données environnementales written by and published by KARTHALA Editions. This book was released on 2006 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: A l'interface des continents nord et sud américains, la Caraïbe se caractérise par de grandes disparités sociétales et biologiques. A la pluralité des environnements physiques correspond une diversité floristique, faunistique, écosystémique et paysagère. Ressource primordiale pour les Amérindiens, les écosystèmes terrestres et marins sont aujourd'hui à l'intersection d'intérêts divers relevant de l'économique et du culturel ou encore de l'aménagement territorial. Les spécificités écologiques, qui sont fonction des différentes terres caribéennes, sont à la base d'usages nouveaux susceptibles de participer au développement économique, par exemple le tourisme. A cette histoire singulière, façonnée par l'action des hommes, s'ajoutent les incommodités naturelles telluriques et atmosphériques, dont les effets directs et indirects ont érigé certaines composantes de cette partie de la biosphère en terre à risques. Les nuisances de toutes sortes, inhérentes au fonctionnement de ces sociétés, sont des freins au développement maîtrisé ou soutenable. Pour l'essentiel, les économies relèvent des propriétés du mal-développement et peuvent entraîner, dans des cas extrêmes, un chaos politique et social. Les conséquences pour les milieux biophysiques sont souvent graves et s'apparentent à un écocide (Haïti par exemple). Le but premier de ce numéro de Terres d'Amérique est d'explorer les différentes facettes du fonctionnement des sociétés caribéennes ainsi que leurs dynamiques d'interface au regard des environnements physiques et biologiques.

Inland Water Resources and Aquaculture Service and published by Food & Agriculture Org.. This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.

Book Synopsis The Mediterranean region under climate change by : Collectif
Download or read book The Mediterranean region under climate change written by Collectif and published by IRD Éditions. This book was released on 2018-11-19 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Book Synopsis Arsenic in Drinking Water by : National Research Council
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
