Managing resources and resolving conflicts: national parks and local people

One of the major management problems in protected areas of developing nations is the ever more intensifying land use disputes with local, often native, people. The customary rights oflocal people over natural resources, if curtailed by the establishment of national parks, and their disregard by decision-makers, have given rise to open conflicts, thus jeopardizing conservation goals. These conflicts have tremendous impact on the management of natural resources, not only within the park ecosystem but also in its surroundings. To attain the interdependent goals of conservation and sustainable development, such disputes must be promptly and consensually settled. This paper briefly discusses the paradigm of national park establishment and its impact on local livelihood. It then highlights major sources of conflict which have occurred in national parks in developing countries. Some theoretical approaches to conflict resolution as relevant to national parks are summarized, and several strategies, as employed in particular situations, are discussed. It is concluded that an in-depth understanding of human ecology beyond the boundaries of parks and the conceptualization of strategies to resolve the innate problems are imperative. The integration of several strategies is deemed essential in order to address issues comprehensively and on a larger scale.     

地方政府与中国乡村的可持续发展——以浙江省横店镇可持续发展实验区为个案

在可持续发展过程中。政府、民间组织、企业和个人都有其能够发挥作用的地方．但是。地方政府可以说是实现地方可持续发展之关键。以浙江省东阳市横店镇可持续发展实验区为个案。深入探讨地方政府与地方可持续发展的关系。文章的一个基本结论是，从横店镇可持续发展实验区案例来看．我国乡村的可持续发展应该走政府主导的模式．而只有强化地方政府的能力（包括规划、资源与领导能力等）。方能培育地方良治（good governance）与支持可持续发展。     

新形势下环境维权发展与研究

随着环境污染形势的加剧、社会民众环保意识的提高,环境维权开始在中国逐渐发展起来,虽然目前仍处于初级阶段,面临着诉讼维权困难、相关体制不健全等众多问题,但环境维权在新形势下已经呈现出诸多新的特征.本文通过对常州外国语学校"常外"事件进行分析,阐述了中国目前环境维权事件所具备的新特征,并在此基础上,从转变政府职能、拓展利益诉求渠道、加强法治力度三个角度出发,对政府管理提出相关建议,希望能够完善环境维权制度、促进环境维权在中国的健康发展.

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。     

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.     

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.
