Incorporation of environmental issues in South Africa’s municipal Integrated Development Plans

The transition to full democracy in South Africa in 1994 saw local government becoming the focal point for dealing with socio-economic development needs of communities. The Integrated Development Plan (IDP) has been used as the tool for guiding local development objectives, balanced against environmental demands within a sustainable development paradigm. Here we examine the extent to which this is being achieved through an analysis of IDPs from 35 different municipalities at three scales. We test the hypothesis that the metropolitan municipalities are better at mainstreaming environmental issues into their IDPs than local and district municipalities. Results indicate that mainstreaming environmental issues in IDPs is still low. The hypothesis that metropoles are better at mainstreaming environmental issues than district and local municipalities was not accepted since there were no significant differences between municipalities. There was low relative budget allocations and inclusion of vision and mission statements that mainstream environmental issues in all municipalities. For mainstreaming of environmental issues to be effective in IDPs, both proactive approaches and multi-faceted bottom-up and top-down approaches are suggested.     

From local sustainable development towards climate change adaptation: a case study of Serbia

The recent 2014 floods in Serbia highlighted the potential extent of climate-related risks in the region, resulting in more than 30 deaths and more than 30,000 displaced people, with the overall cost of the damage close to €1.5 billion. By the end of this century, Serbia will experience an increase in temperature of up to 4°C and a decrease in summer precipitation of up to 50%. Adaptation to those changes calls for the redefinition of a strategic approach and the integration of climate change challenges into the processes of local sustainable development planning. The objective of this study was to assess current local sustainable development strategies (LSDSs) and highlight some of the threats and opportunities which may help or hinder the adaptation process, the evaluation of development priorities, coordination mechanisms at the local level and risk management practice. Based on climate trends and vulnerability level, 20 of the potentially most vulnerable municipalities in Serbia were selected. The analysis shows that although local sustainable development planning still lacks cross-sectorial planning practice and risk management plans and measures, and does not yet recognize vulnerable sectors as climate sensitive, it can still serve as a platform for adaptation planning. Based on the assessed LSDS framework, the most suitable approach to the development of an adaption strategy is the vulnerability-based approach. At the same time, the potential for initiating adaptation planning is recognized in the utilization of already established networks with external and international donors and planning experts, joined county or regional adaptation planning, and cross-border collaboration.     

石家庄地区气温变化和热岛效应分析

选用石家庄地区17个气象观测站40年(1961-2000年)的平均气温资料,应用气候学、气候统计中的数学方法,对该地区的气温变化状况和城市热岛效应特征进行了分析.结果表明:40年里石家庄地区气温呈上升趋势,1981年是气温升高的显著跃变点;石家庄城市热岛效应明显,40年里热岛强度平均为0.59 ℃;其平均增温率为0.006 6 ℃/a,尤其是20世纪80年代以后,热岛强度增加趋势明显,1981-2000年热岛强度平均值较1961-1980年平均值升高了0.10 ℃;石家庄市热岛强度的增加与市区已建成区面积扩大有密切的关系.      

地方政府短期行为对环境管理的制约及其对策

经济体制转型期,地方政府的短期行为为给基层环境管理带来一系列负面影响,这是造成目前地方环境问题的重要因素之一。这个问题的存在,有思想、体制、管理、监督诸方面的原困,必须相应采取措施防止和克服地方政府短期行为对环境管理的制约。     

Towards sustainable local economic development: the UK experience

Despite a growing interest by academics and policy makers in sustainable development, there have been relatively few attempts to examine the economic development implications of adopting such policies. This is especially true at the local level, where very few studies have been undertaken. This paper attempts to remedy this situation through an investigation of strategies introduced by local authorities in the United Kingdom. Existing policies are examined and suggestions made for future policy developments.     

Natural resource depletion and the economic performance of local districts: suggestions from a within-country analysis

SUMMARY

Studying the interactions among ecological factors and economic performance measured at the local scale is necessary to suggest policies able to mitigate natural resource depletion in complex ecosystems, like those in the Mediterranean region. The aim of this paper is to explore the relationship among natural resource depletion due to land degradation (LD) and some economic characteristics of local labour systems in Italy, a country where many areas, especially southern regions, are vulnerable. LD was estimated using an environmental sensitive area index, covering the national territory at a fine scale, which takes into account ecological factors such as climate, soil and vegetation. Economic indicators used here consider per capita income, land productivity, production and labour productivity by sector (agriculture, industry and services). A regression analysis was built-up at the LLS scale using an index change over time (1990–2000) as dependent variable and economic variables as predictors. A principal component analysis (PCA) was carried out to synthesise the outputs of the regression analysis. Results indicate a negative relationship among per capita income and LD over the whole study area. However, other variables showed a significant correlation with the dependent variable, highlighting the importance of local factors to increase land vulnerability. In order to clarify the contribution of economic factors to natural resource depletion it is necessary to drive integrate policies to combat LD in dry Mediterranean areas.

局部通风机实际特性的近似处理方法及应用研究

针对目前局部风机特性曲线很难得到或应用而导致局部通风研究受限问题,提出一种根据局部风机风量及风压范围近似求解风机特性曲线的方法。该方法采用一次线性插值函数代替风机特性曲线函数,结合风阻特性曲线得到风机工况。基于该方法可进行局部风机选型或预测既定型号风机工况点及风筒出口风量,同时可确定长距离掘进通风中钻孔通风有效风量与钻孔长度、直径的关系,也可确定风库中转位置与风筒长度的关系。应用分析结果表明:用一次函数代替稳定区域风机特性曲线函数不仅简单方便,结果较精确,且方法可靠、实用性高。
