Apples, Pears and Porridge: The Origins and Impact of the Search for ''Coherence'' between Humanitarian and Political Responses to Chronic Political Emergencies

During the 1990s a consensus emerged within the international humanitarian system that there was a need to enhance the 'coherence' between humanitarian and political responses to complex political emergencies. Closer integration between aid and political responses was seen to be necessary in order to address the root causes of conflict-induced crises, and to ensure that aid did not exacerbate political tensions. This paper explores the theory and practice of coherence over the past decade. It argues that, by sleight of hand, the coherence agenda has been reinterpreted such that humanitarian action has become the primary form of political action, rather than merely a substitute for it. The coherence agenda has been driven by geopolitical events, domestic policy considerations in donor countries and the more parochial concerns of aid policy, and is reflected in a number of substantive changes in the humanitarian architecture. Many of the tenets of this 'new humanitarianism' have been embraced by the majority of relief agencies, and thus legitimised it. The paper concludes that political humanitarianism, as opposed to active engagement by political and military actors, is flawed ethically and technically. It will provide neither an effective palliative for the ill effects of war, nor address its causes.     

Climate Change in the Baltic Sea Region: A Cross-Country Analysis of Institutional Stakeholder Perceptions

Before climate change is considered in long-term coastal management, it is necessary to investigate how institutional stakeholders in coastal management conceptualize climate change, as their awareness will ultimately affect their actions. Using questionnaires in eight Baltic Sea riparian countries, this study examines environmental managers' awareness of climate change. Our results indicate that problems related to global warming are deemed secondary to short-term social and economic issues. Respondents agree that problems caused by global warming will become increasingly important, but pay little attention to adaptation and mitigation strategies. Current environmental problems are expected to continue to be urgent in the future. We conclude that an apparent gap exists between decision making, public concerns, and scientific consensus, resulting in a situation in which the latest evidence rarely influences commonly held opinions.     

Factors determining the fluctuation of fluoride concentrations in PM10 aerosols in the urbanized coastal area of the Baltic Sea (Gdynia, Poland)

Fluoride concentrations were determined in PM10 samples collected in the urbanized coastal area of the Baltic Sea (Gdynia) in the period between 1 August 2008 and 8 January 2010. F^? concentrations remained within the range of 0.4–36.6 ng?·?m^?3. The economic transformations which have taken place in Poland increasing ecological awareness have had an excellent effect on the levels of fluoride pollution in the air of the studied region. In our measurements, fluoride concentrations increased in wintertime, when air temperature dropped, at low wind speeds (<1 m?·?s^?1) and with low dispersion of pollutants originating from local sources (traffic, industry, domestic heating). At times when wind speed grew to >10 m?·?s^?1, fluorides were related to marine aerosols or else brought from distant sources. Apart from wind speed and air temperature, other significant meteorological parameters which determined the variability of F^? turned out to be air humidity and precipitation volume. Aerosols were washed out effectively, even with small precipitation (h?=?4 mm), and if a dry period lasted for several days, their concentrations grew rapidly to over 30.0 ng?·?m^?3.     

Control of upland bank erosion through tidal marsh construction on restored shores: Application in the maryland portion of Chesapeake Bay

During the period of 1972 through 1993, Environmental Concern Inc. (EC) and its recent (1989) affiliate Environmental Construction Company (ECC) have completed 216 marsh construction projects to control upland bank erosion in tributaries of the Maryland portion of Chesapeake Bay. Of these projects, 26 have involved marsh construction on unaltered existing shores and 190 have utilized marsh construction on shores that have been restored to former increased elevations through shoreline filling and grading. This paper describes the latter restoration technique. Throughout the 21-year period of applying the technique for long-term upland bank erosion control, refinements to the design standards and criteria for site suitability have been made so as to optimize its successful application. As a result of this experience, a reliable bioengineering restoration technique has evolved to control upland bank erosion. This paper describes the details of this successful technique through a review of: (1) its objectives and benefits, (2) suitability of sites for its application, (3) the design of its shore restoration, (4) its construction, (5) its maintenance, and (6) comparison of its cost with those of structural techniques for bank erosion control. Although the technique has only been applied in the Maryland portions of Chesapeake Bay, its applicability should, with modifications, be broadly applicable to all water bodies.     

Profiles of enzymatic activity in earthworms from zinc, lead and cadmium polluted areas near Olkusz (Poland)

The aim of the study was to determine whether there are signs of adaptation of soil fauna to a gradient of heavy metal contamination. Earthworms Aporrectodea caliginosa, Lumbricus terrestris and Eisenia fetida were collected during the spring and summer of 2000 and 2001 from meadow sites situated between 2 and 32 km from the Bukowno-Olkusz complex of zinc-lead ore mines and smelters. The heavy metal content in the soil near smelters reaches 10,500 mg/kg (d.w.) for Zn, 2600 mg/kg for Pb and 81.9 mg/kg for Cd. The sites differ with respect to species composition of earthworm community, with A. caliginosa being dominant. Complete data was obtained only for A. caliginosa, since other species were not abundant at all investigated sites during the whole period of investigation. The body burdens of Zn, Pb, Cd and Cu in A. caliginosa reached 1500, 100, 220 and 10 microg/g, respectively, in the vicinity of the smelter (2-4 km), and decreased to 400, 2, 36 and 6 microg/g at the most distant site (32 km). Cadmium and lead content was significantly elevated in the whole body of L. terrestris collected at the site 2.5 km distant from the smelters when compared to more distant sites, while in E. fetida only the body burden of cadmium was elevated at the nearest site compared to the next site of transect. Activities of glutathione peroxidase (GPX; EC 1.11.1.9) against hydrogen peroxide (H2O2) or cumene hydroperoxide (cumOOH), glutathione reductase (GR; EC 1.6.4.2), glutathione S-transferase (GST; EC 2.5.1.18) and catalase (CAT; EC 1.11.1.6) were assayed in postmitochondrial supernatant obtained from whole body homogenates. Seasonal and annual variations of enzyme activity were reflected by higher GPX activity in the late summer of 2001 in comparison with the spring and summer of 2000. This may reflect severe drought in the spring and summer of 2000. The activity of both GPX isozymes, GR and GST in A. caliginosa and L. terrestris increased with increasing distance from the smelters and reached maximum at sites III and IV (4 and 8 km from the smelters, respectively) and then it decreased in the animals from site V (32 km). These may be the effects of antagonism between the enzyme inducing and enzyme inhibiting action of smelter emissions, a phenomenon known as a hormetic effect. It is postulated here that this effect is of diagnostic value for metal pollution biomonitoring.     

Genotoxicological effects of some phenoxyherbicides and their metabolites on Bacillus subtilis M45 Rec- and H17 Rec+ strains

Because they are used in a number of commercial preparations phenoxyacetic acids and their salts can occur in wastewater. During their degradation genotoxic substances may be created. The results of investigations of biodegradability and genotoxicity of some phenoxyherbicides are presented. Commercial formulations of 2,4-D (Aminopielik 720) and MCPA (Chwastox Extra) were the substrates studied. Biodegradation tests were conducted according to OECD guidelines for testing of chemicals--confirmatory test (OECD Method 303 A). Genotoxicity tests were conducted with Bacillus subtilis strains according to the method of [Chemical Mutagens, vol. 6, Plenum Press. New York, 1980, p. 149]. Genotoxicity of biodegradation products was also studied. Both commercial formulations were biodegradable. Aminopielik 720 was potentially genotoxic but only at great concentrations while Chwastox Extra was not genotoxic. Biodegradation products of neither compound were genotoxic.     

Compliance and Emissions Trading under the Kyoto Protocol: Rules for Uncertain Inventories

A solution is proposed for proving compliance with emission targets and for emissions trading in the event of uncertainties in reported emission inventories. The solution is based on the undershooting concept, from which the mathematical conditions for both proving compliance with a risk α and calculating effective emissions for trading are derived. Based on the reported emission units, the number of permits granted is reduced in proportion to the uncertainty in the inventory. A country whose inventory has higher uncertainty is thereby allotted fewer permits than a country with the same inventory but smaller uncertainty.     

A framework for analysis of contamination on human and ecological receptors at DOE hazardous waste site buffer lands

This article discusses a framework and tools for evaluating ecological resources and the effects of cleanup on hazardous waste sites, particularly those with ecological buffer lands. Environmental professionals are faced with assessing the risks of contamination to humans and ecological receptors (organisms and ecosystems) at hazardous waste sites. While exposure assessment has focused largely on human receptors, environmental managers have recently taken a broader view, recognizing the intrinsic value and aesthetic importance of ecological resources and services, and of including a range of stakeholders in remediation decisions. The assessment process involves understanding exposure pathways from source to receptor, and determining how best to interdict these pathways. Environmental characterization and exposure assessment, indicator and biomarker identification, and biomonitoring and surveillance are the major components of ecological assessments. Using the Department of Energy as a case study, this article offers a framework for ecological exposure assessment, recognizing that humans are important components of ecosystems and, like other biota, are exposed to contaminants that move through environmental media. © 2007 Wiley Periodicals, Inc.     

Efficiency of energy delivery systems: I. An economic and energy analysis

Energy-return-on-investment (ERI) analysis is a variation of more traditional cost-benefit analyses, a variation that is particularly important in times of diminishing fuel resources. We present a simple set of procedures for ERI analysis and apply those procedures to central New York State, where there is a proposal for a new 870 MW_e coal-fired generating station. We compared the energy and dollar costs of building that facility with the costs of an alternative comprehensive regional program of insulation. The analysis showed that regional insulation was more efficient in conserving energy than the plant was in providing it by at least a factor of 4 in economic terms and by a factor of more than 15 when viewed as energy returned on energy invested.
