城市交通与环境可持续发展指标体系评估系统研究——上海案例应用

可持续发展是一种将社会发展概念从单纯经济增长拓展到经济、社会、环境协调发展的城市发展新模式.交通环境的可持续发展在整个发展体系中占据着重要地位.本文针对目前大城市普遍面临的交通环境压力和经济、交通与环境系统的复杂性,通过构建经济-交通-环境间的压力与响应关系,建立了可用于"回顾过去、解析现状、瞻望未来"的城市交通环境可持续发展指标体系.采用隶属函数对单项指标进行标准化处理,对交通环境可持续发展综合指数的评价,采用层次分析法确定各指标的权重.采用Visual Basic 6.0及Office的Access 2000,开发了交通环境可持续发展指标体系评估系统,并以上海市为案例进行了研究.本系统的开发可为城市交通环境可持续状况评价及发展对策的制定提供技术支持.     

特大城市集群绿色发展与生态足迹关联特征

本文以成渝城市群、长江中游城市群和长三角城市群为研究对象,解析不同空间尺度下绿色发展与生态足迹时空变化特征,并结合耦合协调度模型、环境库兹涅茨曲线（EKC）理论探究绿色发展与生态足迹的关联特征。研究表明,长江经济带城市群2000—2015年绿色发展水平逐年提升,约16.44%的城市达到较高水平,空间上呈现“东部高、西部低”的特征。人均三维生态足迹增长逐渐趋缓,成渝城市群达到峰值（5.21hm²）后逐年稳定下降。长江经济带绿色发展与生态足迹处于良好协调状态,绿色经济的快速发展带动了耦合协调度的提高。绿色发展与生态足迹存在倒“ U”形EKC曲线关系,由于自然资源基础和产业结构差异,成渝城市群（拐点出现在2008年）绿色发展与生态足迹协调关系好转早于中下游城市群（拐点分别在2019年、2012年）。四川、安徽应作为降低资源消耗的重点对象,未来应进一步加强区域中心城市的辐射带动作用,拉动周围城市提高绿色发展水平。研究成果能为区域绿色发展与生态环境协同管理提供思路与理论支持。     

上海市“十四五”规划绿色发展驱动因素研究

本文首次以上海市“十四五”规划的视角,使用系统动力学方法研究上海市的绿色发展因素。首先确定了由经济、社会、环境、资源四个子系统交叉融合而构成上海市绿色发展系统,再基于系统动力学原理和上海市2012—2019年的数据构建上海市绿色发展模型,响应“十四五”规划在绿色发展方面设立的目标,构建多个未来发展情景并进行指标参数调控,依据各个情景的仿真结果,分析并总结了“十四五”规划背景下上海市的绿色发展特点。研究结果表明,影响绿色发展的关键因素由主到次依次为生态环境建设支出、研发支出、产业结构调整。相比于产业的投资结构调整,上海市对从业人员结构的调整可以高效平衡经济与环境的发展;加快科技创新可以在很大程度上抑制碳排放,从而快速实现上海市的“双碳”目标;针对化学污染物的治理,污染源防治不但十分有效,而且有利于持续性发展,这些措施应是上海市政府的首选。     

Spatial analysis of resources and environmental carrying capacity in Iran

Urbanization and mass movement of the population from rural areas and small cities to megacities have led to environmental, economic, and social problems in Iran. In dealing with these challenges, assessing resource and environmental carrying capacity (RECC) is considered an effective method to leverage space and capital to achieve sustainable development. This study aimed to rank the provincial RECC in Iran. Toward this purpose, environmental indices were generated from remotely sensed and statistical census data. Then, the provinces were scored in terms of environmental, economic, and infrastructural carrying capacities, and RECC using the mean variance analysis method. Results demonstrated that in most areas, there is no relationship between economic and infrastructural capacities and development. Statistically, a correlation coefficient of −0.53 between economic and environmental carrying capacities indicated excessive use of environmental capacities. Moreover, the spatial distribution pattern of environmental, economic, and infrastructural carrying capacity was entirely heterogeneous between the provinces; there was a northeast–southwest pattern in terms of infrastructural capacity and an economic pattern from north to south. The distribution pattern of RECC is most consistent with the environmental capacity, pointing at the high weight of the indicators of the RECC model. In conclusion, this research offers a new vision for policymakers and provides a theoretical and applicable framework for implementing sustainable strategies in land-use planning. It is recommended that the RECC concept and tools can be used not only for planning but also for measuring the efficiency of spatial development programs and establishing land balances in the region.     

Institutional quality,financial development and sustainable economic growth among lower income countries

This article postulates strong endogenous relationships in lower income countries between institutional quality, financial development and sustained economic growth. These associations were investigated using the vector-error correction model (VECM) and Granger causality method for a sample of 79 countries from 2005 to 2022. The findings show that (1) these variables reinforce each other in the short run. (2) In the long run, both institutional quality and financial development can fuel economic growth. (3) The positive effect of institutional quality on economic growth is greater than that of financial development. Policy implications of these findings are that careful attention should be paid to co-development policies to enhance the institutional quality and the financial system in these economies. Policies should also consider economic growth strategies to enable sustainable economic growth rates.     

How does eliminating mercury from artisanal and small-scale gold mining lead to achieving sustainable development goals?

Artisanal and small-scale gold mining (ASGM) is the principal anthropogenic activity that globally contributes to overloading our environment with mercury. Although the Minamata Convention, led by the United Nations, is a crucial instrument to eliminate its use progressively, novel approaches to accelerate this difficult transition are welcome. This article proposes a framework for policy-making or improvement, fostering the enforcement of mercury elimination through the lens of the 17 Sustainable Development Goals (SDGs), focusing on the excluded artisanal and small-scale gold miners and their dependents. We move forward with a literature review of the Artisanal and Small Mining topic, taking each SDG as a unit of analysis. Understanding the problem as a puzzle of four sets of pieces, namely: (1) social, (2) environmental, (3) economic, and (4) institutional, the paper offers potential opportunities for the decision-makers and practitioners to accelerate the substitution of this heavy metal and develop sustainable futures for the ASGM communities. We conclude by proposing a pragmatic framework that synthesizes the means, actions, and ends to accelerate a sustainable transition.
