Описание: The workshop was also able to play a role in examining the agroforestry systems encountered in temperate and Mediterranean areas, including both traditional and more innovative agroforestry practices.
Описание: Comprises a selection of contributions presented at a workshop held in Montpellier in 1997. The two main objectives of the workshop were to bring together what is understood about the processes underlying agroforestry practice, and to provide a forum to explore models and modelling approaches.
Описание: This book consists of a series of papers that help to unravel the taxonomy of the phylum Brachiopoda and describe associated marine communities in the Levant. These faunas inhabited shallow shelf environments near the boundary of the Indo-African and Tethyan faunal realms near the Jurassic equator along the southern Tethyan margin. This research is part of a long term project that aims to delineate the distribution of brachiopods across faunal realm boundaries and reconstruct the biogeographic history of the region. The work provides a more detailed analysis of the endemism that is characteristic of the faunas of northern Sinai, the Negev and Jordan, and will also aid in the construction of a biogeographic framework for Jurassic strata in the Middle East. It represents an important contribution to our knowledge of the evolution of modern marine communities because their roots lie in the ecological diversifications of the Jurassic.

Описание:
In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon dioxide have led to a severe depletion of the carbon pool in the world's soils. This is especially telling in developing countries where tropical climates further compromise the soil's ability to recover.
In Climate Change and Global Food Security, bestselling editor Rattan Lal heads up a team of the world's top soil scientists and ecologists to document the history of this impending agricultural crisis and explore possible solutions. Throughout this timely text, the authors address six complex themes: 1. The impact of projected climate change on soil quality, water resources, temperature regime, and growing season duration on net primary productivity of different biomes 2. Soil carbon dynamics under changing climate 3. The impact of changes in carbon dioxide and ecological environments on agronomic yields and food production in different regions of the world 4. World food demands and supply during the 21st century 5. Policy and economic issues related to carbon trading and enhancing agricultural production 6. Research and development priorities for enhancing soil carbon pool and food security This hard-hitting text is essential reading for anyone involved with soil and crop sciences as well as policy makers and change agents who need to come to the forefront of this issue armed with the latest information and viable solutions.

Описание: This edited volume focuses on the challenge to food security posed by a changing climate, with chapters exemplifying many of the critical issues through empirical studies undertaken in Sub-Saharan Africa and the Caribbean.
Описание: In Search of Biohappiness deals with methods of converting agro-biodiversity hotspots into happy spots. This involves concurrent attention to conservation, and sustainable and equitable use.
