Agriculture is often considered as one of the main threats to ecosystems. Unsustainable farming practices often result in habitat loss, inefficient use of water, soil degradation, pollution, genetic erosion, among other negative impacts on human life, including hunger, low food quality, reduced access to food resources, as well as the abandonment of rural areas. Nevertheless, when agriculture is practiced in a sustainable way, it can contribute to the preservation of many habitats, to the protection of watersheds, to the preservation and improvement of soil health. The use of sustainable and ecological practices is the key feature distinguishing traditional agriculture from intensive one. It...
Research in recent years has increasingly shifted away from purely academic research, and into applied aspects of the discipline, including climate change research, conservation, and sustainable development. It has by now widely been recognized that “traditional” knowledge is always in flux and adapting to a quickly changing environment. Trends of globalization, especially the globalization of plant markets, have greatly influenced how plant resources are managed nowadays. While ethnobotanical studies are now available from many regions of the world, no comprehensive encyclopedic series focusing on the worlds mountain regions is available in the market. Scholars in plant sciences worldwi...
The Geomorphological Hazards of Europe contains an excellent balance of authoritative statements on the range and causes of natural hazards in Europe. Written in a clear and unpretentious style, it removes myths and concentrates on the basic facts.The book looks at the known distributions, processes and the underlying principles and focuses on the need for a true understanding of the scientific details so that a real contribution to hazard management can be made.A comprehensive treatment of scientific and management issues of hazards in Europe caused by natural or sometimes human induced earth surface processes are covered including floods, landslides, avalanches, glacier-, coastal-, karstic...
This volume comprises a selection of papers describing the main features of the Lanzarote and Chinijo Islands Geopark (Canary Archipelago, Spain). Of all the Global Geoparks worldwide, it is the only one that has officially evaluated and characterized specific areas as analogues for the geological and astrobiological exploration of Mars. The identification and characterization of terrestrial sites that can be used as planetary analogues are currently considered vital study areas of planetary geology and astrobiology. Written by experts in the various fields, this multidisciplinary book is a unique resource for graduate students and professionals alike.
I turisti che arrivano a Lanzarote cercando sole e mare non resteranno delusi: le sue spiagge sono tra le migliori delle Canarie. Lanzarote, però, offre molto più di una piacevole vacanza al mare: un quarto della superficie di Lanzarote è una landa vulcanica di aspra bellezza, mentre il resto dell’isola è verde e armonioso, ma disseminato di curiosi paesaggi creati proprio dalla sua natura vulcanica...

Global environmental challenges such as climate change, rapid urbanization, and human influence on the environment continue to grow. Many of these resulting risks lead to diseases and negative impacts on health and quality of life. It is now essential to develop more sustainable and healthy environments with greater focus on prevention by targeting the root causes of disease. Urban communities comprise a high concentration of services, consumption, and waste and represent an unsustainable pattern of urbanization that accelerates the decline of global ecosystems services rather than supporting them through the compensatory contributions of peri-urban and rural areas. By focusing on reducing e...
The symposium "Prehistoric Iberia: genetics, anthropology and linguistics" was held in the Circulo de Bellas Artes, Madrid on 16th -17th November 1998. The idea was bringing together specialists who could address not clearly resolved historic and prehistoric issues regarding ancient Iberian and Mediterranean populations, following a multidisciplinary approach. This was necessary in the light of the new bulk of genetic, archeological and linguistic data obtained with the new DNA technology and the recent discoverings in the other fields. Genes may now be easily studied in populations, particularly HLA genes and markers of the mitochondrial DNA and the Y chromosome. Basques, Iberians, North Af...
The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.
This study presents a contrasting hypothesis concerning the genesis and development of Islam in Mexico than the one generally held across academic spheres and current historiography. It demonstrates that Colonial and Early Independent Mexico and Islam may have as well known about the existence of each other. However, within the chronological framework in which the Viceroyalty of Nueva España lived and developed there were social hindrance, geopolitical imperatives and theological impediments and cosmovisions – in both sides of the Atlantic – that created the quasi– perfect circumstances for the Islamic tradition and Mexico not to really meet. This book provides new angles of study on the theme, and with it, new historiographical approaches.
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.
