Via approximately 80 entries or "mini-chapters," the SAGE 21st Century Reference Series volumes on geography will highlight the most important topics, issues, questions, and debates any student obtaining a degree in this field ought to have mastered for effectiveness in the 21st century. The purpose is to provide undergraduate majors with an authoritative reference source that will serve their research needs with more detailed information than encyclopedia entries but not so much jargon, detail, or density as a journal article or a research handbook chapter. Features & Benefits: Curricular-driven to provide students with initial footholds on topics of interest in writing research term papers, in preparing for GREs, in consulting to determine directions to take in pursuing a senior thesis, graduate degree, etc. Comprehensive to offer full coverage of major subthemes and subfields within the discipline of geography, including regional geography, physical geography, global change, human and cultural geography, economic geography and locational analysis, political geography, geospatial technology, cartography, spatial thinking, research methodology, geographical education, and more. Uniform in chapter structure to make it easy for students to locate key information, with a more-or-less common chapter format of Introduction, Theory, Methods, Applications, Comparison, Future Directions, Summary, Bibliography & Suggestions for Further Reading, and Cross References. Available in print and electronic formats to provide students with convenient, easy access.

The biosphere reserve concept was first launched in the mid-1970's, as part of UNESCO's international programme 'Man and the biosphere' (MAB), and has now become a practical field approach to combining the conservation of biological diversity with sustainable development needs. This publication has been prepared to mark the 30th anniversary of the MAB Programme. It provides an overview of the origins and development of the concept and its implementation, and goes on to consider recent activities and publications. It also discusses the difficulties and challenges in implementing the concept in different social, cultural, economic and biogeographic contexts.

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.

The Seville Strategy spurred a signifi cant paradigm shift in UNESCO's MAB Programme, re-conceptualising the research programme as a modern tool for the dual mandate of nature conservation and sustainable development. However, many biosphere reserves failed to comply with the new regulations and in 2013 the 'Exit Strategy' was announced to improve the quality of the global network. This study presents a global assessment of the implementation of the quality enhancement strategies, highlighting signifi cant differences worldwide through 20 country-specifi c case studies. It concludes that the strategies have been fundamental in improving the credibility and coherence of the MAB Programme. Challenges in the implementation were not unique to individual countries but were common to all Member States with pre-Seville sites, and in many states the process has led to a rejuvenation of national biosphere reserve networks.
