Selected AbstractsDer Census of Marine Life zieht Bilanz.BIOLOGIE IN UNSERER ZEIT (BIUZ), Issue 4 2010Globale "Volkszählung" unter Wasser Abstract Ein internationales Großprojekt zur Erfassung der Vielfalt des Lebens im Meer, der Census of Marine Life, wird nach zehn Jahren in diesem Herbst mit einer großen Abschlussveranstaltung in London zu Ende gehen. Mit einer Vielzahl von Teilprojekten wurde das Leben von den tropischen Stränden über Seeberge, hydrothermale Quellen und polare Meere bis in die Tiefseebecken untersucht, um einen Überblick über die Artenvielfalt zu bekommen und Erkenntnisse darüber zu gewinnen, wie die Vielfalt des Lebens im Meer beeinflusst und gesteuert wird. Einige der Teilprojekte werden beispielhaft dargestellt, insbesondere das Projekt CeDAMar, das vom Senckenberg-Institut geleitet wird. CeDAMar erforscht die großen Tiefseebecken, die etwa die Hälfte der Erdoberfläche ausmachen und noch sehr wenig bekannt sind. Der wachsende Rohstoffbedarf rückt diesen bisher weitgehend unbeeinflussten Lebensraum in das Interesse der Industrie, und Experten von CeDAMar haben durch ihre Fachkompetenz bei der Erstellung von Richtlinien zum Schutz des Meeresbodens in internationalen Gewässern einen sehr konkreten Beitrag geleistet. Global Underwater Census , a large-scale project is taking stock The Census of Marine Life, an international large-scale project to assess the diversity of life in the ocean, will end this fall after a decade of discovery with a grand finale in London. Many so-called field projects were established to study life from tropical beaches, seamounts, hydrothermal vents, to polar seas and abyssal plains in order to get a better estimate of marine species diversity and gain insight into processes that influence the diversity of life in the oceans. Some of the field projects are presented, including the project CeDAMar under the leadership of the Senckenberg Institute. The study area of CeDAMar is abyssal plains, which comprise about half of the Earth's surface yet are very little known. Mankind's growing demand on minerals and other resources has awoken the industry's interest in a part of the ocean that so far has been relatively pristine. CeDAMar scientists have helped with their expertise to establish guidelines for the protection of the seafloor in international waters, thus demonstrating how concrete the influence of deep-sea exploration on human society can become. [source] Foreign direct investment and hydropower in Lao PDR: the Theun-Hinboun hydropower projectCORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 4 2006Maarit Virtanen Abstract This paper examines the impact of foreign direct investment and especially the role of hydropower projects in achieving national development goals in the Lao PDR. It focuses on the environmental and social impacts of large-scale projects by using the Theun-Hinboun hydropower project as an example of controversies related to development interventions affecting livelihoods dependent on the natural resource base. Findings suggest that even though the Theun-Hinboun hydropower project has evolved into a kind of model project, several questions related to the final impact on poverty reduction, mitigation of environmental and social impacts and the participation of project affected people remain open. The relative success of Theun-Hinboun may not be easily repeated, especially as planned new hydropower schemes cause even more profound impacts on still largely subsistence based livelihoods and the environment.

[source] A tale of two cities: restoring water services in Kabul and MonroviaDISASTERS, Issue 4 2009Jean-François Pinera Kabul and Monrovia, the respective capitals of Afghanistan and Liberia, have recently emerged from long-lasting armed conflicts. In both cities, a large number of organisations took part in emergency water supply provision and later in the rehabilitation of water systems. Based on field research, this paper establishes a parallel between the operations carried out in the two settings, highlighting similarities and analysing the two most common strategies. The first strategy involves international financial institutions, which fund large-scale projects focusing on infrastructural rehabilitation and on the institutional development of the water utility, sometimes envisaging private-sector participation. The second strategy involves humanitarian agencies, which run community-based projects, in most cases independently of the water utilities, and targeting low-income areas. Neither of these approaches manages to combine sustainability and universal service. The paper assesses their respective strengths and weaknesses and suggests ways of improving the quality of assistance provided. [source] Linking ecological theory with stream restorationFRESHWATER BIOLOGY, Issue 4 2007P. S. LAKE Summary 1. Faced with widespread degradation of riverine ecosystems, stream restoration has greatly increased. Such restoration is rarely planned and executed with inputs from ecological theory. In this paper, we seek to identify principles from ecological theory that have been, or could be, used to guide stream restoration. 2. In attempts to re-establish populations, knowledge of the species' life history, habitat template and spatio-temporal scope is critical. In many cases dispersal will be a critical process in maintaining viable populations at the landscape scale, and special attention should be given to the unique geometry of stream systems 3. One way by which organisms survive natural disturbances is by the use of refugia, many forms of which may have been lost with degradation. Restoring refugia may therefore be critical to survival of target populations, particularly in facilitating resilience to ongoing anthropogenic disturbance regimes. 4. Restoring connectivity, especially longitudinal connectivity, has been a major restoration goal. In restoring lateral connectivity there has been an increasing awareness of the riparian zone as a critical transition zone between streams and their catchments. 5. Increased knowledge of food web structure , bottom-up versus top-down control, trophic cascades and subsidies , are yet to be applied to stream restoration efforts. 6. In restoration, species are drawn from the regional species pool. Having overcome dispersal and environmental constraints (filters), species persistence may be governed by local internal dynamics, which are referred to as assembly rules. 7. While restoration projects often define goals and endpoints, the succession pathways and mechanisms (e.g. facilitation) by which these may be achieved are rarely considered. This occurs in spite of a large of body of general theory on which to draw. 8. Stream restoration has neglected ecosystem processes. The concept that increasing biodiversity increases ecosystem functioning is very relevant to stream restoration. Whether biodiversity affects ecosystem processes, such as decomposition, in streams is equivocal. 9. Considering the spatial scale of restoration projects is critical to success. Success is more likely with large-scale projects, but they will often be infeasible in terms of the available resources and conflicts of interest. Small-scale restoration may remedy specific problems. In general, restoration should occur at the appropriate spatial scale such that restoration is not reversed by the prevailing disturbance regime. 10. The effectiveness and predictability of stream ecosystem restoration will improve with an increased understanding of the processes by which ecosystems develop and are maintained. Ideas from general ecological theory can clearly be better incorporated into stream restoration projects. This will provide a twofold benefit in providing an opportunity both to improve restoration outcomes and to test ecological theory. [source] Overcoming the Glass Barriers: Reflection and Action in the ,Women to the Top' ProgrammeGENDER, WORK & ORGANISATION, Issue 2 2008Ulla Eriksson-Zetterquist Numerous equality programmes have been launched with the aim of promoting a more gender equal work life, yet little substantial action has been reported. This article presents a study of the Women to the Top programme in Sweden, supported by the European Union (EU) and aimed at promoting more women into top management positions. The research suggests that large-scale projects assembling such heterogeneous actors as industry representatives, politicians and scholars tend to generate further reflection and discussion rather than promoting adequate and highly needed action. Drawing upon Brunsson's distinction between action rationality and decision rationality, the relatively modest effects of large-scale equality programmes are examined, not in terms of a lack of commitment or competence on the part of the participants but as a matter of the disjunction between reflection and action. Reconciling reflection and action, that is, emphasizing not only reflection on gender inequality but also privileging various forms of practical action (such as new policies, the appointment of female managers, restructuring gendered wage inequalities or new recruitment procedures), is therefore a top priority for policymakers desiring more substantial changes in the gendered outline of industry.
