Download or read book Water Resources in Mexico written by Úrsula Oswald Spring and published by Springer Science & Business Media. This book was released on 2011-08-26 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.
Download or read book State of knowledge of soil biodiversity Status challenges and potentialities written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-12-04 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is increasing attention to the importance of biodiversity for food security and nutrition, especially above-ground biodiversity such as plants and animals. However, less attention is being paid to the biodiversity beneath our feet, soil biodiversity, which drives many processes that produce food or purify soil and water. This report is the result of an inclusive process involving more than 300 scientists from around the world under the auspices of the FAO’s Global Soil Partnership and its Intergovernmental Technical Panel on Soils, the Convention on Biological Diversity, the Global Soil Biodiversity Initiative, and the European Commission. It presents concisely the state of knowledge on soil biodiversity, the threats to it, and the solutions that soil biodiversity can provide to problems in different fields. It also represents a valuable contribution to raising awareness of the importance of soil biodiversity and highlighting its role in finding solutions to today's global threats.
Download or read book Diversity of Ecosystems written by Mahamane Ali and published by BoD – Books on Demand. This book was released on 2012-04-27 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the function of ecosystems, modelling, sampling strategies, invading species, the response of organisms to modifications, the carbon dynamics, the mathematical models and theories that can be applied in diverse conditions.

Book excerpt: La agroecología puede fortalecer a las comunidades marginadas, restaurar los ecosistemas y proteger las fincas de la destrucción ecológica, al mismo tiempo aporta para frenar el el cambio climático. Estas prácticas son efectivas pero todavía no se aplican en todo el mundo. El libro Tierra Fértil, editado por el director ejecutivo de Groundswell International Steve Brescia, nos presenta nueve ejemplos en los cuales los campesinos dirigen movimientos agroecológicos en sus comunidades. Su trabajo en África, Latinoamérica, el Caribe, América del Norte y Europa profundiza las prácticas agroecológicas en muchas comunidades , estas prácticas y principios los comparten con los métodos de Campesino a Campesino, y establecen estructuras organizativas que apoyan a organizaciones gubernamentales y civiles. Tierra Fértil nos muestra métodos para expandir la agroecología con comunidades rurales para que ellas se beneficien con sus propias soluciones y sabiduría.

It will take a broad view of this sophisticated and complex industry, and will examine the practice of sustainable tourism from global travel trends through to destination and site management. Innovative solutions, including those involving ecological tourism are particularly welcome, as well as cultural initiatives that will lead to better approaches to tourism with the objective of preserving the diversity of our planet.

Download or read book Tourism as a Challenge written by Maria F. Schmitz and published by WIT Press. This book was released on 2013 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first tourist destinations were primarily consolidated in the early twentieth century. Since then, tourism has undergone significant changes in its economic and social components. Over time, many of these destinations have now come to represent 'mass tourism' and are the subject of many studies on the impacts of tourism and competitiveness policies. The conclusions of these studies point to the need for new perspectives and strategies ranging from adaptation to new contexts to a radical change in targets. Concepts such as 'sustainability', 'nature', 'biodiversity' or 'climate change' have now been added to the tourism industry with varying degrees of knowledge and skill. These offer a great opportunity to improve a model of tourism previously oriented towards business and the institutional rhetoric of "sustainability" – a fact now recognised by tourists as representing the negative effects of conventional tourism.Management of these innovations should include among its aims environmental education and orient visitors towards awareness and respect for sustainability even outside their leisure time. To this end, the tourist needs to be made aware of all those involved and their commitment to managing the destination, as enjoying the territory should be based upon minimising the socio-ecological impacts of tourism, and on motivating nature conservation and participation of local populations in both these goals, as well as in the economic benefits obtained. The challenge entails the destination finding a good balance between economic and cultural benefits, landscape conservation and tourist satisfaction. This fifth volume of the Tourism Today Series presents a collection of papers addressing the how to manage these types of uses at a variety of destinations and in multiple contextual realities. These edited papers were selected from those presented at different international conferences organised by the Wessex Institute of Technology. They address important issues related to tourism as a tool for development which will give a better understanding of some of the current challenges.
Download or read book Temperate Agroforestry Systems written by Andrew M Gordon and published by CABI. This book was released on 2018-03-07 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic animal production has increased rapidly in recent years to keep up with the increasing consumer demand for organic meats. There are many guidelines and restrictions on what should go into the feedstuffs of organically farmed animals, from which difficulties arise when trying to ensure a well-balanced, nutritious diet without the use of any supplements. The book has been completely updated and revised to address how to formulate organic diets in situations where there is a declining supply of organic feed, as well as the feasibility of utilizing novel feedstuffs and their acceptability by consumers of organic meat products. Including the experiences of producers in relation to appropriate breeds and production systems for forage-based organic production, this book is an important read for researchers and students of organic food animal production, veterinary sciences and food; as well as food industry personnel and organic farmers.
