State of the environment reporting (SoER) is a well-established and widely applied environmental management tool in the South African context. Despite a wealth of knowledge about conducting and preparing SoERs, there is a paucity of research on the effect SoER has had on decision-making at the local government sphere. This study investigated the effect of SoER on decision-making for a sample of municipalities in the Gauteng Province of South Africa. The methodology relied on interviews with key role players, which include the ‘‘environmental function’' as well as ‘‘other functions’' responsible for infrastructure development and planning within the municipalities. The results show that notwithstanding the extensive time and resources spent on SoER, it appears to have had a limited effect on decision-making, especially beyond the environmental function. Recommendations to improve the influence of SoER on decision-making in developing countries include improved clarity on the purpose and home of SoER within municipalities, adequate budget and capacity, and effective cooperative governance both within the municipalities, and with other spheres of government.  相似文献

For almost 50 years, the Council of Europe through a series of documents has been helping to build up a set of rules, principles, and strategies related to culture, environment, ethics, and sustainable development. At the moment, one of the most important aims of the Council of Europe’s agenda deals with the elaboration of the General Principles for the Protection of the Environment and Sustainable Development, as raised in document CO-DBP (2003)2 related to the environmental subject. The intention of the Council of Europe is to encourage national authorities to implement these General Principles into their national environmental policies. These principles should have an important effect, especially in those countries which are new members of the European Union. The primary target of this paper is the study of these principles and the setting of their entailed implications in order to establish a relation between values and policy making. Quite often, the conclusions adopted by the agreements generated within the framework of the European Union are controversial. Therefore, a study aiming to lay the foundations of these principles will make the exchange of ideas easier, providing a wider and more detailed scope in the European environmental policy.  相似文献

Governments, NGOs, and natural scientists have increased research and policy-making collaborations with Indigenous peoples for governing natural resources, including official co-management regimes. However, there is continuing dissatisfaction with such collaborations, and calls for better communication and mutual learning to create more “adaptive” co-management regimes. This, however, requires that both Western and Indigenous knowledge systems be equal participants in the “co-production” of regulatory data. In this article, I examine the power dynamics of one co-management regulatory regime, conducting a multi-sited ethnography of the practices of researching and managing one transnational migratory species, greater white-fronted geese (Anser albifrons frontalis), who nest where Koyukon Athabascans in Alaska, USA, practice subsistence. Analyzing the ethnographic data through the literatures of critical geography, science studies and Indigenous Studies, I describe how the practice of researching for co-management can produce conflict. “Scaling” the data for the co-management regime can marginalize Indigenous understandings of human–environment relations. While Enlightenment-based practices in wildlife biology avoid “anthropomorphism,” Indigenous Studies describes identities that operate through non-modern, deeply imbricated human–nonhuman identities that do not separate “nature” and “society” in making knowledge. Thus, misunderstanding the “nature” of their collaborations causes biologists and managers to measure and research the system in ways that erase how subsistence-based Indigenous groups already “manage” wildlife: by living through their ethical commitments to their fellow beings. At the end of the article, I discuss how managers might learn from these ontological and epistemological differences to better “co-produce” data for co-management.  相似文献

This study reports on the biocultural dimensions of the tasat (Arenga obtusifolia Griff.) tree and its conservation by various informal institutions of the Adi tribe of Arunachal Pradesh, India. The study included 240 Adi community members (120 men and 120 women) residing in 12 villages of the East Siang and Upper Siang districts of Arunachal Pradesh. The study was conducted using personal interviews and participatory methods. Results indicated that the stem of tasat is used as a traditional food during droughts and in preparing an ethnic beverage. Tasat is being conserved by the Adi tribe in various habitats. Plant populations of tasat were observed relatively higher in Upper Siang than the East Siang district. The study found differences in the status of biocultural knowledge between genders and different age groups. Kebang and reglep are two indigenous institutions of men and women, respectively, and play leading roles in sustaining tasat plants in various habitats. Women of the Upper Siang district still maintain a knowledge network for diffusing biocultural knowledge related to tasat, among others, through a barter system. Changing land use patterns in agriculture affects tasat conservation. The value addition for tasat based products, and rewarding women who conserve tasat, can enhance the sustainability of tasat based on biocultural knowledge and institutions.  相似文献

Water is an essential element for humankind, animals, and plants. It is also an important element of the aquatic environment (the natural habitat of multiple species), where its quality plays a determining role in their protection and conservation. Unfortunately, the water quality of natural environments has worsened in the last decades. In sub-Saharan Africa and particularly in Bénin, in contrast to river discharges, monitoring the quality of surface water is a very rare activity. Thus, knowledge about physical and chemical properties as a basis for evaluation of the state of the environment and protection measures needed is almost absent. This article presents the results of the first structured, regular monitoring campaign on surface waters in the whole basin of the Ouémé River in Bénin Republic. With 510 km, the Ouémé River’s water quality fluctuates from upstream (Taneka Koko mountains in the north) to downstream (gauging station Bonou in the south) sources. This is due to soil erosion, lack of water treatment plants, and the use of significant quantities of fertilizer in the cotton zone. The present research was initiated to study the resource degradation of this area through chemical and physical water analysis. The monitoring of water quality has been followed for 5 years on twenty physicochemical parameters, from samples taken at four gauging stations on the main channel of the Ouémé River. Means and standard deviations of water analysis results were compared to both the recommendations of the World Health Organization (WHO) and the Maximum Permissible Concentrations (MPC) for drinking water (WHO 1987). Thus, high values were observed for physical parameters, i.e., color and turbidity had peaks of 697.5 uC and 129 FTU at Bétérou station in the wet season, although certain parameters, such as total hardness, present low values compared to the recommended standards. Moreover, excluding the concentrations of NO2 and NH4 + with values above the MPC, nutrient concentrations posed no direct risk for human consumption. However, together with phosphate concentrations (which are up to ten times higher than permissible ecological thresholds), they can cause eutrophication of the aquatic ecosystem. Due to the current flow regime, which has very low discharge rates in the dry season and torrential rainfall and high sediment loads in the wet season, the risk of eutrophication, i.e., excessive concentrations of ammonium and phosphates, is present throughout the year. Accumulation of ammonium and the distribution of nitrate and nitrites in the river water suggest that nitrification is impeded due to a lack of oxygen in both dry and wet seasons. Finally, the investigations show that the risk of water pollution exists and it is necessary to take measures of sanitation and water treatment to prevent the further degradation of water along the Ouémé River.  相似文献

The European Union's Structural Funds are implemented by means of Regional Development Plans (RDP), whose regionally scoped environmental assessment is required. We highlight the deficiencies faced by this approach when subregional areas with high conservation natural values are involved and illustrate it with the case of the RDP of Andalusia region on Doñana National Park area (Spain). Commissioned by the World Wildlife Fund, a Strategic Environmental Assessment (SEA) of the Andalusian RDP was carried out focusing on Doñana and its area of influence. This is a complex space where some of the most environmentally valuable features in the continent coexist with a surrounding intense and multi-sector economic activity, threatening its conservation. In the absence of an established sustainability framework in the Region, a “trickle-down” SEA approach evidenced the need to produce a set of environmental, economic and social guidelines for sustainable management of land, against which the RDP objectives were tested for coherence. An “incremental” SEA approach was also tested, which involved the identification of 79 measures and actions stemming from the RDP provisions and other concurrent planning documents reviewed and the qualitative assessment of their individual and cumulative potential impacts on Doñana environments. In the light of the results, a set of complementary mitigating measures was proposed for inclusion in tiered stages of the planning process. Measures to avoid, reduce, remedy and monitor the major types of impact were proposed, including provisions for public participation. SEA emerges as an instrument for non-governmental organizations (NGOs) to carry out independent assessment of public development initiatives.  相似文献

The application of organic wastes to improve soil physical characteristics in mechanized vineyards planted after land levelling is becoming a common practice in Mediterranean areas. It may be useful as an additional source of organic matter and nutrients, but these wastes could also have negative effects due to their metal content. The aim of the study was to evaluate the influence of compost application on soil metal contents in mechanized vineyard soils of the Spanish Mediterranean area, where this practice is repeated every three years. The study was carried out in a ten-year-old vineyard where the main soil type is Typic Calcixerept. Composted cattle manure was applied in alternate rows, at a rate of 40 Mgha(-1) dry-weight. Nine sampling points were located along the slopes of two plots: a levelled plot prepared for mechanization with large soil disturbance movements within the plot, and a plot of undisturbed soil. At each location, soil samples were taken in both treated and untreated soils. Total concentrations (digestion with aqua regia) and the extractable DTPA (Diethylene-triaminepentacetic)-CaCl2-TEA (Triethanolamine) fractions of Cu, Zn and Mn were analyzed in each sample. For Cu and Zn, the initial concentration was higher in the undisturbed plot. In both cases, total Cu and total Zn were positively affected by manure input and the concentration in treated soils was significantly higher than in untreated soil. For Mn, the initial concentration was higher in disturbed soils than in undisturbed ones, and although in both scenarios the concentrations increased with manure, no significant differences were found between treated and untreated soils. The extractable fraction also increased in treated versus untreated soils, although for Cu and Mn the extractable/total metal ratio was similar in treated and untreated soils. After one compost application, total metal contents increased significantly, particularly for Zn. Most of those metals are accumulated in the soil, due to the soil characteristics.  相似文献

A large number of studies have documented 20th century climate variability and change at the global, hemispheric, and regional levels. However, understanding the implications of climate change for environmental management necessitates information at the level of the ecosystem. Historical monitoring data from the Chesapeake Bay estuary were used to identify temporal patterns of estuarine temperature anomalies in the surface (1 m) and subsurface (15 m) between 1949 and 2002. Data indicated a trend in surface and subsurface warming of +0.16°C and +0.21°C per decade, respectively, driven by warming during winter and spring. These trends suggest warming of the estuary since the mid-20th century of approximately 0.8–1.1°C. Estuarine temperatures correlated well with other independent data records for sea surface and surface air temperatures in the region and to a lesser extent, the northern hemisphere. Gross long-term temperature variability in the estuary was consistent with North Atlantic climate variability associated with the prolonged positive North Atlantic Oscillation/Arctic Oscillation and increased anthropogenic radiative forcing, although localized environmental drivers likely are important as well. A simple spatial analysis revealed strong seasonal latitudinal and longitudinal gradients in estuarine temperature as well as a north–south gradient in long-term temperature trends. Continued warming of the estuary will have important implications for ecosystem structure and function as well as attempts to manage existing challenges such as eutrophication and benthic hypoxia. However, such management efforts must be cognizant of the effects of various climate and nonclimate drivers of environmental variability and change operating over different spatial and temporal scales.Published online  相似文献

On the basis of the cross-section and time-series data of the Lower Mekong Basin (LMB)—including large sections of Thailand, Lao PDR, Vietnam, and Cambodia, we find little evidence in support of the environmental Kuznets curve (EKC) hypothesis. Instead, our regressions support the general views that water pollution had been positively related to income level and that, as a result of the end of the Cold War era, it had been significantly reduced in the 1990s vis-à-vis the 1980s. In most circumstances, water resources were more seriously polluted in the transnational border areas than in the other areas. Specifically, the estimated coefficients on the political boundary dummies show that political influence on transnational water pollution was more significant in areas near the international border along which the river runs (denoted by BORDER2) than in places near the international border across which the river runs (denoted by BORDER1). The estimated coefficients on the ASEAN dummy present some information about the positive role of the Association for Southeast Asian Nations (ASEAN) membership in the reduction of transnational water pollution. Finally, the country-specific dummies are found to present conflicting information about the transnational differences of water pollution, although Thailand is found to have the least water pollution in the LMB.  相似文献

This paper is an attempt to examine issues and problemsraised by agricultural biotechnology by drawing on the richnessof contemporary ideas in ethical theory and thereby contribute tothe project of establishing new approaches to these problems. Thefundamental argument is that many of the negative aspects ofagricultural biotechnology are generated at the level of theunderlying conceptual frameworks that shape the technology'sinternal modes of organization, rather than the unintendedeffects of the application of an inherently benevolent set oftechniques. If ``food ethics' is to address the adverse impacts ofagricultural biotechnology, it must ultimately challenge theseconceptual frames, which, I argue, emerge from Enlightenment,liberal, political, and economic theory.The translation of traditional bioethics (focusing on principlessuch as autonomy and rights, justice, and well being) into foodethics does not produce the critical tools that are ableadequately to challenge the harmful legacy of Enlightenmentthinking. What is needed are reorientations of ethics that arecapable of formulating concepts and approaches that to someextent break with the presuppositions that underpin biotechnologyat its foundation. This paper suggests that narrative andfeminist critiques of medical bioethics are a good place to startin this project.  相似文献

This article aims to interrogate manifold features, uses and manifestations of the term sustainability through critical reflection on paradoxes of “sustainable development.” This article will discuss the implication of the environmental Kuznets curve hypothesis, postmaterialist values theory, and ecological modernization theory all of which expresses a certain relationship between the wealth of a nation and their environment impact. According to these theories, during early industrialization and development, economies use materially intensive resources, until a threshold is reached after which the economic and technological changes allow for more sustainable material use. Simultaneously, it is believed that concerns about environment are secondary to economic concerns and that satisfaction of material needs will lead to higher environmental awareness. The aim of this article is to reflect upon a gap in the literature of empirical case studies to support or refute these theories. While there is a wealth of publications detailing various unsustainable practices in different countries, studies addressing the implication of the accuracy of the triple theories for the global enterprise of development are rare. To compensate for this oversight, this article will address the case of Dutch Queen’s day celebrations in April 2013, based on the document analysis. In generalizing the case of Dutch Queen’s day celebrations to global consumption patterns, this article considers consequences of Western consumption model for the enterprise of global development. It is argued that the Dutch case supports evidence of the (un)sustainability of a consumptive economy operating within a global market. Alternative framework based on cradle-to-cradle and circular economy approaches is proposed.  相似文献

The urban groundwater of the central Besòs river basin (the La Llagosta aquifer) has become contaminated due to the infiltration of wastewater from septic tanks and sewage networks, and by industrial activities located in urban areas. The groundwater hydrogeochemistry of the La Llagosta aquifer was characterized using isoconcentration maps, hydrogeochemical diagrams (Piper, Schoeller-Berkaloff) and by analyzing hydrogeochemical changes along a flow-path that crosses an urban and peripheral industrial area in the main alluvial aquifer (the La Llagosta unit). The evolution of cations, anions and heavy metals along the flow path and the use of the PHREEQC numerical code indicate a complex set of geochemical processes, which result from the interaction between the sources of pollution, the groundwater flow and the mineral composition of the aquifer materials. The contaminated groundwater below the urban areas shows high contents of NO(3)(-) (90-100 mg/L) and an increase in the concentrations of Ca(2+) and Mg(2+) which coincides with a decrease in pH. The Eh shows greater variation than the pH along the flow line studied, with values ranging between 56 mV in the industrial area and 370 mV in the urban area. The area with the lowest Eh value coincides with the highest concentrations of dissolved Fe (4.7 mg/L) and Mn (0.22 mg/L).  相似文献

Abstract

This article reports the findings of a qualitative study with residents living in six deprived neighbourhoods in the UK and the front-line workers and local policymakers responsible for the renewal of these areas. The study was an attempt to raise awareness of local environmental concerns in the context of a national and local policy agenda, which has, until recently, largely overlooked the impacts of degraded environments on the lives and activities of the people who live in them. A key aim for the study was to raise people's concerns with local decision-makers and examine how far these might be addressed through the existing financial, administrative and legislative arrangements for neighbourhood renewal in the UK, namely Local Strategic Partnerships. The research was designed to provide practical lessons and policy recommendations for others wishing to raise the profile of environmental justice in the context of neighbourhood level regeneration projects, in both the UK and elsewhere in the ‘developed’ world.  相似文献

Water planning processes in Australia have struggled to account for Indigenous interests and rights in water, including the use of Indigenous knowledge in water management. In exploring the role of Indigenous knowledge in government-led water planning processes, how might tensions between Western scientific and Indigenous knowledges be lessened? Drawing on two case studies from northern Australia we examine how Indigenous knowledge is represented and managed as a different social knowledge to that of Western science in a management context where legal and planning conventions assume priority. The role of Indigenous (social) knowledges in developing options and strategies for sustainable water management is contingent upon the participation of Indigenous people in water planning. We suggest that water planning processes must contain the possibility of an explicit approach to mutual recognition and consequent translation of the conceptual and pragmatic bases of water management and planning in both Western scientific and Indigenous domains.  相似文献

This paper explores citizens’ views about the welfare of farmed fish and the mental abilities of fish with a large survey data sample from Finland (n = 1,890). Although studies on attitudes towards animal welfare have been increasing, fish welfare has received only limited empirical attention, despite the rapid expansion of aquaculture sector. The results show that the welfare of farmed fish is not any great concern in the Finnish society. The analysis confirms the distinct character given to farmed fish compared to traditional farmed animals. Salmon are rated low in their mental abilities, including the capacity to feel pain, which may weaken ethical concerns for fish welfare. When analyzing the social determinants surrounding the rating of the welfare of farmed fish, it was shown that fish welfare attitudes follow general animal welfare attitudes regarding age and place of residence as fish welfare tends to be rated more negatively among younger age groups and among urban residents. However, no clear connection could be identified between gender and the rating of fish welfare, which may suggest that the distinct cultural categorization of fish diminishes the typical gender difference identified in animal attitudes. It is concluded that in order to improve awareness about fish welfare, there is a need to increase dissemination of scientific knowledge about fish and their welfare. Moreover, further research should be directed toward studying the moral positioning of fish and the distinct moral categorization they receive.  相似文献

Stakeholders in plantation forestry are increasingly aware of the importance of the ecosystem services and non-market values associated with forests. In New Zealand, there is significant interest in establishing species other than Pinus radiata D. Don (the dominant plantation species) in the belief that alternative species are better suited to deliver these services. Significant risk is associated with this position as there is little objective data to support these views. To identify which species were likely to be planted to deliver ecosystem services, a survey was distributed to examine stakeholder perceptions. Stakeholders were asked which of 15 tree attributes contributed to the provision of five ecosystem services (amenity value, bioenergy production, carbon capture, the diversity of native habitat, and erosion control/water quality) and to identify which of 22 candidate tree species possessed those attributes. These data were combined to identify the species perceived most suitable for the delivery of each ecosystem service. Sequoia sempervirens (D.Don) Endl. closely matched the stakeholder derived ideotypes associated with all five ecosystem services. Comparisons to data from growth, physiological and ecological studies demonstrated that many of the opinions held by stakeholders were inaccurate, leading to erroneous assumptions regarding the suitability of most candidate species. Stakeholder perceptions substantially influence tree species selection, and plantations established on the basis of inaccurate opinions are unlikely to deliver the desired outcomes. Attitudinal surveys associated with engagement campaigns are essential to improve stakeholder knowledge, advancing the development of fit-for-purpose forest management that provides the required ecosystem services.  相似文献

Studies of collaborative watershed groups show that effective leadership is an important factor for success. This research uses data from in-depth interviews and meeting observation to qualitatively examine leadership in a Midwestern collaborative watershed group operating with government funding. One major finding was a lack of role definition for volunteer steering-committee members. Lack of role clarity and decision-making processes led to confusion regarding project management authority among the group, paid project staff members, and agency personnel. Given the important role of government grants for funding projects to protect water quality, this study offers insight into leadership issues that groups with Clean Water Act Section 319 (h) funds may face and suggestions on how to resolve them.  相似文献

This Translations contribution presents the 10th issue of the series Frei.Räume (in English: Free spaces), edited by the German Feminist Organisation of (female) Planners and Architects (FOPA) in 1998. The issue was titled “New roads – new goals. Positions of feminist planning” and reflected the contemporary discussions on the state of the art of feminism, gender and planning. While progress was recognized, many authors felt uncomfortable with the ways that feminist concerns had been implemented into planning, and they were looking for ways forward. Among the authors were the most important protagonists of the debates at the time. Looking at the issue today, it becomes clear that many concerns are as up to date as they were in the late 1990s, although circumstances have changed. The paper argues that it is worthwhile to pay attention to these feminist debates in order to develop future strategies for feminism in planning.  相似文献
