This book was released on 2017-05-16 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: INNOVATE was a comprehensive, collaborative, and binational research project. It ran from January 2012 through December 2016. Brazil and Brazil’s Northeast in particular suffered from a severe drought period from 2012 onwards. Management and governance of natural resources faced serious challenges related to access to water. Important long-term drivers that call for recurrent adaptation of actions are land use change, population growth, climate change, and conflicts from the multiple uses of water. The scientific project addressed this complex situation through research aimed at suggesting practices and pathways towards ecologically and socioeconomically sound management of land, water and biodiversity. The INNOVATE project had one focus on the entire watershed of the São Francisco River and another one on a portion of the watershed – the Itaparica Reservoir and the semi-arid area north of the artificial lake. Researchers with different backgrounds worked within their disciplines, in groups (interdisciplinary) and together with stakeholders (transdisciplinary). The Guidance Manual is a compilation of actor-relevant content extracted from the scientific research results. Most recommendations put forward can be adapted as principles and standards for reservoir and semi-arid regions elsewhere in the world. INNOVATE war ein umfassendes, bi-nationales Verbundforschungsprojekt zwischen Brasilien und Deutschland, mit einer Kernlaufzeit von Januar 2012 bis Dezember 2016. Im Jahr 2012 begann eine besonders schwere Dürreperiode, welche nicht nur den sowieso trockenen Nordosten Brasiliens traf, sondern auch weitere Teile des Landes. Die stark eingeschränkte Wasserverfügbarkeit wurde zum zentralen Thema von Management und Governance der natürlichen Ressourcen. Wichtige langfristige Treiber, welche eine kontinuierliche Anpassung des Handelns notwendig machen, sind Landnutzungsänderungen, Bevölkerungswachstum, Klimawandel und Konflikte um die verschiedenen Wassernutzungsansprüche. Im Projekt wurden Praktiken und Ansätze zur ökologisch und sozialökonomisch verträglichen Bewirtschaftung von Wasser, Land und Biodiversität entwickelt. Das Studiengebiet des INNOVATE-Projekts umfasste dabei das gesamte Wassereinzugsgebiet des São Francisco Flusses, wobei Feldforschung im semi-ariden Umland nördlich des Itaparica Stausees stattfand. Forscher und Forscherinnen aus verschiedenen Disziplinen arbeiteten disziplinär, in Gruppen (interdisziplinär) sowie gemeinsam mit Stakeholdern (transdisziplinär). Das vorliegende Handbuch ist eine Zusammenstellung von Stakeholder-relevanten Empfehlungen, welche aus den Ergebnissen der wissenschaftlichen Forschung abgeleitet wurden. Die meisten hier vorgestellten Handlungsempfehlungen können weltweit an vergleichbare Stausee- und semi-aride Regionen angepasst werden.

Available in PDF, EPUB and Kindle. Book excerpt: The planning and management of water resources aiming to a sustainable development must necessary pass through a series of studies that will reveal the interrelations and links among economic activities, and If one considering that there is a set regions involved in the process, the direct and indirect regional interdependencies. Increasing demands of water-use for industrial, agricultural and urban sectors may became very competitive and can result in conflicts among multiple users. In the case of the São Francisco River Basin, Brazil, consisting of a wide-range five states - most of them having drought problems - the water in the basin plays an essential role and any activity in this area has to consider the effects of the water use in the intersectoral and interregional economic relations. Considering the three main states in the basin - Minas Gerais, Bahia and Pernambuco - an interregional input-output system for the economy and for the water flows was constructed by the authors. The above interregional system is then used to analyse the interregional and intersectoral dependencies among the states and the economic activities on the São Francisco river basin area and their relations with the use of water.

The book also aims to bring researchers’ attention to the potential of tropical microorganisms for biotechnological purposes, an area that is still far from being well explored.
Download or read book Review of the state of the world fishery resources Inland fisheries written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-05 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.

Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Available in PDF, EPUB and Kindle. Book excerpt: This book represents an interdisciplinary approach to the relevant aspects of agricultural production related to the interactions between natural processes, human activities and the environment. It provides condensed and comprehensive knowledge on the functions of various agroecosystems at the field, landscape and global scale. Understanding and integrating complex ecological processes into field production, land management and food systems is essential in order to deal with the challenges of modern crop and livestock production: the need for food security for the growing human population, and the necessity to combat the detrimental effects of food production on the environment. The book provides the scientific basis required by students and scientists involved in the development of sustainable agroecosystems and contributes to a range of disciplines including Agriculture, Biology, Geography, Landscape Ecology, Organic Farming, Biological Control, and Global Change Ecology.
Download or read book The Ecology of River Systems written by Bryan R. Davies and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the ecology of running waters has come a long way during the past few years. From being a largely descriptive subject, with a few under tones concerned with such things as fisheries, pollution or control of blackflies, it has evolved into a discipline with hypotheses, such as the River Continuum Concept (Vannote et a/. 1980), and even a book suggesting that it offers opportunity for the testing of ecological theory (Barnes & Minshall 1983). However, perusal of the literature reveals that, although some of the very early studies were concerned with large rivers (references in Hynes 1970), the great mass of the work that has been done on running water has been on streams and small rivers, and information on larger rivers is either on such limited topics as fisheries or plankton, scattered among the journals, or not available to the general limnologist. The only exceptions are a few books in this series of publications, such as those on the Nile (Rz6ska 1976), the Volga (Morduckai Boltovskoi 1979) and the Amazon {Sioli 1984), and the recent compendium by Whitton (1984) on European rivers, among which there are a few that rate as large.

Download or read book Aquaculture Innovation and Social Transformation written by Keith Culver and published by Springer Science & Business Media. This book was released on 2008-09-15 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the ‘green revolution’ before it, the ‘blue revolution’ in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture’s ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam,nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).

Download or read book PAHs written by Peter E. T. Douben and published by John Wiley & Sons. This book was released on 2003-07-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.

Available in PDF, EPUB and Kindle. Book excerpt: World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.
Download or read book Ecological Data written by William K. Michener and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists are increasingly tackling difficult issues like global change, loss of biodiversity and sustainability of ecosystem services. These and related topics are enormously challenging, requiring unprecedented multidisciplinary collaboration and rapid synthesis of large amounts of diverse data into information and ultimately knowledge. New sensors, computers, data collection and storage devices and analytical and statistical methods provide a powerful tool kit to support analyses, graphics and visualizations that were unthinkable even a few years ago. New and increased emphasis on accessibility, management, processing and sharing of high-quality, well-maintained and understandable data represents a significant change in how scientists view and treat data. These issues are complex and despite their importance, are typically not addressed in database, ecological and statistical textbooks. This book addresses these issues, providing a much needed resource for those involved in designing and implementing ecological research, as well as students who are entering the environmental sciences. Chapters focus on the design of ecological studies, data management principles, scientific databases, data quality assurance, data documentation, archiving ecological data and information and processing data into information and knowledge. The book stops short of a detailed treatment of data analysis, but does provide pointers to the relevant literature in graphics, statistics and knowledge discovery. The central thesis of the book is that high quality data management systems are critical for addressing future environmental challenges. This requires a new approach to how we conduct ecological research, that views data as a resource and promotes stewardship, recycling and sharing of data. Ecological Data will be particularly useful to those ecologists and information specialists that actively design, manage and analyze environmental databases. However, it will also benefit a wider audience of scientists and students in the ecological and environmental sciences.
