What is the state of geographical education in the second decade of the 21st century? This volume presents a selection of peer reviewed papers presented at the 2012 Cologne Congress of the International Geographical Union (IGU) sessions on Geographical Education as representative of current thinking in the area. It then presents (perhaps for the first time) a cross-case analysis of the common factors of all these papers as a current summary of the “state of the art” of geographical education today. The primary aim of the individual authors as well as the editors is not only to record the current state of the art of geographical education but also to promote ongoing discussions of the longer term health and future prospects of international geographical education. We wish to encourage ongoing debate and discussion amongst local, national, regional and international education journals, conferences and discussion groups as part of the international mission of the Commission on Geographical Eduction. While the currency of these chapters in terms of their foci, breadth and recency of the theoretical literature on which they are based and the new research findings they present justifies considerable confidence in the current health of geographical education as an educational and research endeavour, each new publication should only be the start of new scholarly inquiry. Where should we, as a scholarly community, place our energies for the future? If readers are left with a new sense of direction, then the aims of the authors and editors will have been amply met.

As the end of the Cold War approached in 1989, Caroline Thomas argued: “It is important that the discipline [International Relations, IR] should address the issue of disease and more broadly, health, not simply to facilitate containment of disease transmission across international borders but also because central notions of justice, equity, efficiency and order are involved” (1989:273).1 Ten years later, Craig Murphy echoed these sentiments. Murphy (2001: 352) proposed that IR had yet to grapple with the political consequences of growing inequality between the world’s rich and poor, and areas such as health—where these inequalities were most stark—should become the field’s core business. How IR’s theories and methods would approach these issues was less clear. Bettcher and Yach (1998) cautioned that IR would be unable to develop progressive research projects that explored global health diplomacy as a global public good without adopting new perspectives and methods. Others warned that the expansion of security studies into areas such as global health would weaken the intellectual coherency of the field (Walt 1991:213). Taking its cue from the recent Ng and Prah Ruger (2011) study, this paper returns to these concerns to briefly explore key trends and potential future concerns of research in IR on health...

Inputs of toxic chemicals provide one of the major types of anthropogenic stress threatening our Nation's coastal and estuarine waters. To assess this threat, the National Oceanic and Atmospheric Administration's (NOAA’s) National Status and Trends (NS&T) Program Mussel Watch Project monitors the concentrations of more than 70 toxic chemicals in sediments and on the whole soft-parts of mussels and oysters at over 300 sites around the U.S. Twenty of the 25 designated areas that comprise NOAA's National Estuarine Research Reserve System (NERRS) have one or more Mussel Watch monitoring sites. Trace elements and organic contaminants were quantified including As, Ag, Cd, Cu, Hg, Ni, Pb, Zn, ΣPCBs, ΣPAHs, DDT and its metabolites, and butyltins. The Mussel Watch sites located in or near the 20 Reserves provide for both status and trends. Generally the Reserves have trace element and organic contaminant concentrations that are at or below the median concentration determined for all NS&T Mussel Watch monitoring data. Trends were derived using the Spearman-rank correlation coefficient. It was possible to determine if trends exist for sites at which six or more years of data are available. Generally no trends were found for trace elements but when trends were found they were usually decreasing. The same general conclusion holds for organic contaminants but more decreasing trends were found than for trace elements. The greatest number of decreasing trends were found for tributyltin and its metabolites. (PDF contains 203 pages)

EAFFRO and UNPP/LVFRP bottom trawl exploratory data have been used to describe the depth distributional pattern. relative abundance and magnitude of the demersai fishes in Lake Victoria. The results have been compared with the commercial catch estimates, and various interpretations of the trends in the annual catches and experimental biomass estimates in relation to possible future developments of the fishery have been suggested. Though it is highly desirable to develop the fishery such as by supplementary trawling, certain social and biological consequences and considerations needs to proceed in graded steps guided by several research disciplines. The past trends of the fisheries of Lake Victoria are briefly considered. Recent exploratory bottom trawl data, by EAFFRO and UNDP/LVFRP, have been used to define demersal fish stocks of Lake Victoria in terms of their magnitude, relative abundance and distribution pattern by depth. Enstence of disparity between the relative abundance of the various species in their commercial catches and in their present biomass estimates is pointed out and the various aspects associated with the necessary modification of the fishing practices are discussed. Further and continuing research of the bio-socio-economic vectors of the fishery will be necessary in order to generate the rationale of an efficient fishing regime for a rational management strategy and realistic utilization of the fishery resource.

This article describes future trends in environmental education (EE) research based on a mixed-methods study where data were collected through a content analysis of peer-reviewed articles published in EE journals between 2005 and 2010; interviews with experts engaged in EE research and sustainability-related fields; surveys with current EE researchers; and convenings with EE researchers and practitioners. We discuss four core thematic findings: (1) EE researchers are highlighting the importance of collective and community learning and action; (2) EE researchers are placing increased emphasis on the intersection of learning within the context of social-ecological communities (e.g. links between environmental quality and human well-being); (3) a pressing need exists for research conducted with urban and diverse populations; and (4) research around social media and other information technologies is of great interest, yet currently is sparse. © 2013 © 2013 Taylor & Francis.
