Poverty Reduction and Sustainable Development   总被引:3,自引:0,他引:3  
The prominent place of the chapter on poverty in the Johannesburg Plan of Implementation (JPI) is totally in keeping with the priority given to poverty reduction in the development thinking of the international community of today. The Johannesburg process did not lead to any new insights or new commitments in the fight against poverty. Section one sets out a factual comparison of the poverty chapters in Rio's Agenda 21 (AG21) and in the JPI. Section two reviews the conceptual links between poverty reduction and sustainable development, since poverty is used both as a dependent and as an independent variable. This analysis shows a shift in the function of growth as related to environmental protection. Section three explores the naturalization of development thinking in its economic and social dimensions and shows how this affects the policy options for social protection. I also explain how social and environmental sustainability have become elements of risk management and how are both aimed at conflict prevention and enhanced growth. Finally, in section four three lines of action are suggested to enhance the emergence of a socially meaningful sustainable development agenda that, ideally, would make poverty reduction strategies redundant.  相似文献

Irrigation management calls for objective criteria capable of representing the economy, reliability, and productivity of irrigation systems. These criteria must be compatible with long-term sustainability and conservation goals. The criteria representing the above goals are the economic effect of management on yield reduction, economic effect, and reliability referring to plant growth and operation of the network. In this study environmental indices are introduced to express the above criteria in quantitative terms. The inclusion of these indices at the farm and network level create a multicriteria framework for decision-making based on composite programming. An experimental study was conducted during the irrigation periods of 1989 and 1990 in Chania, Greece, concerning water delivered to 40 experimental plots, soil moisture content at the rootzone, and irrigation system operational failures. The data collected in real time were used for the calculation of the corresponding environmental indices. The variation in time and space is high and resulted in up to 62% of yield loss and low system performance (up to 7% of system temporal reliability). The study indicated that environmental indices could be incorporated to select alternatives and also to develop policies on water delivery. The final decision involves a trade-off analysis between cost of application and desired system performance. Measures of both primary objectives can be obtained using environmental indices that represent system operation aggregation at its basic levels (on farm and network).  相似文献

ABSTRACT: The cost of water service to rural residents is very high compared to urban areas. This is true even after subsidization by Farmers Home Administration (FmHA) loans and grants. Capital cost data on 44 projects financed by the Ohio office of the FmHA during the period August 1968 to January 1977 are used to derive cost equations for 26 components of rural water distribution systems. These components represent 92 percent of the capital cost of the pipeline distribution systems studied. The data can be used to economically design rural water supply systems from a capital cost viewpoint. More data are needed on operation and maintenance costs as well as central and cluster well costs before totally economic system designs can be undertaken.  相似文献

Local environmental policies are sometimes seen as standing in the way of socio-economic progress. Against the background of these concerns, the actual socio-economic impacts of climate protection measures are discussed in this paper. It is structured as follows. First, the concept of primary and secondary effects of climate policies is introduced. Secondly, there is a discussion of financial and economic impacts of local climate policies. Finally, information is given on the consequences of such measures for local energy security and air quality. The main conclusion is that, at least in the field of climate policies, there is a huge potential for local measures that are socioeconomically attractive to local communities. HAUKE VON SEHT, Impactos socio-económicos de políticas del medio ambiente local, un análisis para el campo de protección climática . Las políticas ambientales locales son vistas algunas veces como si estuvieran en la via del progreso socio-económico. En contra de los antecedentes de estos asuntos, los impactos socio-económicos actuales de las medidas de protección climaticas son discutidos en este documento. Está extructurado de la siguiente manera: Primero serán introducidos el concepto de efectos primarios y secundarios de las políticas climáticas. Luego sigue una discusión de impactos económicos y financieros de las políticas climáticas locales, seguido por información de las consecuencias de tales medidas para la calidad del aire y seguridad de energía local. La conclusión principal es que por lo menos en el campo de las políticas climáticas hay un inmenso potencial de medidas locales que son socio-económicamente actractivas a las comunidades locales.  相似文献

The structural-temporal organization of a murine rodent community in the taiga has been studied near Lake Teletskoe, Mountain Altai. The results show that the long-term dynamics of indices characterizing community diversity depend mainly on changes in the structure of dominance rather than on the population dynamics of species. The distribution of species in the factor space corresponds to their preference for certain biotopes, from dry to relatively moist. An analysis of relationships within the rodent community has revealed the synchronous dynamics of species abundance and antiphase pattern of changes in the structural indices of dominant species.  相似文献

基于能值的哈萨克斯坦可持续发展评价   总被引:1,自引:0,他引:1  
运用能值方法分析2014—2018年哈萨克斯坦的资源利用和可持续发展状况。结果表明:哈萨克斯坦的总能值使用量约有89.94%依赖于本土不可更新资源,且直接出口大量粗加工原材料(如石油、矿产、金属等)。该国能值货币比率较低(9.50×1011~1.22×1012 sej/$),单位货币所购买能值量较小;能值产出率在16.87~26.11范围内波动,从基于能值的可持续发展指数来看,2014年该指数为0.90,系统发展缺乏可持续性;2015—2018年,该指数高于1,系统发展是可持续的。此外,哈萨克斯坦环境负荷较高,主要由于对本土不可更新资源的开采及利用效率较低。对此,提出了加强可再生资源开发力度、提升资源利用效率、改善对外贸易结构等建议,以期为促进哈萨克斯坦的可持续发展提供科学依据。  相似文献

Coastal-zone sustainability policies are socially constructed. It follows that their effective implementation depends on the sustainable voluntary co-operation of stakeholders with competing interests and priorities. No form of integrated coastal-zone management can nurture such co-operation as long as the objective is to determine ‘best’ policies, derived by expert-based rational analysis, instead of seeking to identify ‘correct’ policies, ones that can draw the maximum possible stakeholder support. The latter task requires a co-operative coastal-zone management that incorporates the relevant public discourse into the policy formation process in a direct, proactive and conflict minimizing manner. Towards this end, four major challenges are examined for maximizing the stakeholders' motivation for voluntary co-operation: (1) optimism about the level of optimism; (2) agenda setting; (3) value discourse; and (4) information and empowerment.  相似文献

Construction and building industry is in dire need for developing sustainability assessment frameworks that can evaluate and integrate related environmental and socioeconomic impacts. This paper discusses an analytic hierarchy process (AHP) based sustainability evaluation framework for mid-rise residential buildings based on a broad range of environmental and socioeconomic criteria. A cradle to grave life cycle assessment technique was applied to identify, classify, and assess triple bottom line (TBL) sustainability performance indicators of buildings. Then, the AHP was applied to aggregate the impacts into a unified sustainability index. The framework is demonstrated through a case study to investigate two six storey structural systems (i.e. concrete and wood) in Vancouver, Canada. The results of this paper show that the environmental performance of a building in Canada, even in regions with milder weather such as Vancouver, is highly dependent on service life energy, rather than structural materials.  相似文献

Theories in risk, psychology, and communication suggest aiming to inform the public about basic ecological facts may not be enough to influence knowledge of risks or behaviors to mitigate water quality risks. The risk information‐seeking and processing model and the theory of planned behavior suggest several additional variables that are likely to influence risk‐mitigating behaviors. We used data from a survey of watershed residents in Ohio to explore a model of behavioral intentions to positively impact stream health. Residents' informational norms, or the perceived pressure to know about local stream health, strongly predicted their information‐seeking behaviors. Active‐seeking behaviors predicted positive attitudes toward behaviors impacting stream health, which predicted intentions to positively impact stream health. Implications for outreach include couching communication in terms of risk found important to the local community, here wildlife were seen as negatively influenced by water quality, as opposed to plain reports typically provided by utility companies. Increasing social pressure to feel informed by emphasizing the existing knowledge of stream ecology among residents could change the norm for the less informed. A low response rate limits the generalizability of findings here, but leveraging these findings in outreach efforts could prove more successful in engaging the public to improve stream health and support policies to improve stream health.  相似文献
