Download or read book Food security and nutrition in the age of climate change written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-17 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: After steadily declining for over a decade, global hunger is on the rise again, while various forms of malnutrition coexist. Climate change is already exacerbating this grim picture, which is why food security and food production will be a major focus of the Intergovernmental Panel on Climate Change’s 6th Assessment Cycle. Thanks to the participation of 250 experts from all around the world, the International Symposium on Food Security and Nutrition in the Age of Climate Change highlighted the importance of food and agricultural systems in the fight against climate change and presented concrete multi-sector solutions to address this global issue. The event placed special emphasis on the regional realities of West Africa and the Canadian North, as well as to the presence of young people and members of Indigenous and Northern communities directly affected by these issues. The summaries of these four days of plenaries, interactive workshops, and special events have been grouped under seven major themes for this publication: 1) Climate change, food security and nutrition: the issues; (2) The agriculture sectors in the context of climate change; (3) Food systems in the face of climate change; (4) Natural resources: challenges and solutions; (5) Food security and nutrition in a changing North; (6) Summary of solutions; (7) Strengthening and adapting regional and international cooperation.

Download or read book The Atlantic Salmon written by Eric Verspoor and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
Download or read book Submarine Mass Movements and their Consequences written by Geoffroy Lamarche and published by Springer. This book was released on 2015-10-02 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive collection of state-of-the-art studies of seafloor slope instability and their societal implications. The volume captures the most recent and exciting scientific progress made in this research field. As the world’s climate and energy needs change, the conditions under which slope instability occurs and needs to be considered, are also changing. The science and engineering of submarine – or more widely subaqueous – mass movements is greatly benefiting from advances in seafloor and sub-seafloor surveying technologies. Ultra-high-resolution seafloor mapping and 3D seismic reflection cubes are becoming commonly available datasets that are dramatically increasing our knowledge of the mechanisms and controls of subaqueous slope failure. Monitoring of slope deformation, repeat surveying and deep drilling, on the other hand, are emerging as important new techniques for understanding the temporal scales of slope instability. In essence, rapid advances in technology are being readily incorporated into scientific research and as a result, our understanding of submarine mass movements is increasing at a very fast rate. The volume also marks the beginning of the third IGCP project for the submarine mass movement research community, IGCP-640 S4SLIDE (Significance of Modern and Ancient Submarine Slope LandSLIDEs). The Submarine Mass Movements and Their Consequences symposium is the biannual meeting under the IGCP umbrella.
Download or read book Mining in Africa written by Bonnie Campbell and published by IDRC. This book was released on 2009-06-15 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continent of Africa is rich in minerals needed by Western economies, but rather than forming the basis for economic growth the mining industry contributes very little to African development Investigating the impact of the 2003 Extractive Industries Review on a number of African countries, the contributors find the root of the problem in the controls imposed on the African countries by the IMF and World Bank. They aim to convince academics, governments and industry that regulation needs to be reformed to create a mining industry favourable towards social, economic and environmental development. The book takes a multidisciplinary approach and provides a historical perspective of each country, making it ideal for students of development studies and development organizations.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.
