Download or read book Extractive Sector and Civil Society written by Flavia Milano and published by Inter-American Development Bank. This book was released on 2018-10-16 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: 4% of Latin America and the Caribbean’s GDP comes from the extractive sector. This figure is equivalent to the amount generated by agriculture in the same region. An effective engagement between governments, companies, and civil society is required to propel sustainable development. With this regional diagnosis of countries rich in natural resources like Argentina, Chile, Colombia, Mexico, Peru, and the Dominican Republic, the IDB seeks to shed light on best practices among stakeholders of the extractive sectors. It focuses in actions of information, dialogues, consultations, collaborations, and partnerships that are driving development in the region. From the findings of the diagnosis, 3 roadmaps were drafted, to guide the stakeholders in strengthening their engagement.

Download or read book The Spanish Coastal Systems written by Juan A. Morales and published by Springer. This book was released on 2018-09-03 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the state of art of the geologic knowledge about the Spanish coast obtained through scientific research in the last 30 years.From a general point of view, coasts are the most quickly changing systems of the Earth. This is critical, since many human resources, such as the main part of economic and social activities, are located in the coastal areas. Especially in the case of Spain these coasts include cities, wide industrial areas (including harbor complexes), important ecologic systems, and our main economic resource: tourism. Understanding the dynamic functioning of each element of this coast is vital for correct future coastal management, so as to solve problems derived from bad plans developed in the last decades of the twentieth century. This is a valuable text for advanced graduate students and coastal researchers, which connects the specific dynamic functioning of the main Spanish coastal environments and their relationships with human activities.

Download or read book The Soils of Argentina written by Gerardo Rubio and published by Springer. This book was released on 2018-05-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book on Argentinian pedology. It discusses the main soil types of Argentina, their geographical distribution, classification, functions, agricultural use, ecological aspects, and the threats to which they have been subjected during centuries of intensive and extensive management. The description of the soils is accompanied by a complete set of data, pictures and maps, including benchmark profiles and an overview of the country's agricultural production. It also deals with future scenarios of the relationships between soil science and other disciplines and the main challenges that soil science will face in the future. Further, the book explores aspects of the main soil forming factors, such as climate, vegetation, geology and geomorphology, making use of new, unpublished data and elaborations, and presents a history of pedological research in Argentina.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.
