Towards a moral socio-environmental economy: A reconsideration of values

In this intervention article I contribute to discussions of moral economy by arguing that scholars should reconsider the nature of value. Neoliberalism considers only exchange value. As a consequence neoliberal policies try to manage problems such as climate change with economic systems and instruments that are mis-calibrated to the material realities they are meant to represent. Value has spatial and temporal characteristics. Recognizing the spatial and temporal dynamics of value leads to new means of resource valuation, such as extending the time-frame of instruments and changing the nature of privatization. In conclusion, I argue for the need for new theories of use value.     

Fairtrade bananas in the Caribbean: Towards a moral economy of recognition

Working through a Caribbean case study, this paper examines the networks and associations of Fair Trade bananas as they move both materially and morally from farms in St Vincent and the Grenadines to supermarkets and households in the United Kingdom. In doing so, the paper provides grounded empirical evidence of Fair Trade’s moral economy as experienced by banana producers in the Caribbean. The paper follows Nancy Fraser’s distinction between ways of framing justice to argue that, in order to transcend its complex postcolonial positionalities, the Fair Trade Foundation needs to include recognition in its moral economy as well as representation and redistribution. The paper compares the moral framework of Fair Trade as an ideology and social movement with the lived experience of certified Fairtrade banana farmers in the Windward Islands who work mostly for, rather than within, an idealized moral economy. The paper also contributes to several recent debates in the agri-food literature exploring the interconnections between production and consumption, the role of materiality in contemporary food networks, the historical and (post)colonial nature of food moralities, and links between political and moral economies of food. Following an outline of recent debates about the moral economies of food and its relation to Fair Trade as a movement, the paper dissects the moral economy of the Fairtrade Foundation, highlighting the historical and geographical, material and symbolic, gendered and generational ways that food producers in the Global South (in this case, banana farmers in St Vincent and the Grenadines) may be counterposed to ‘responsible’ consumers in the Global North. Despite the good intentions of those who promote the Fair Trade movement through the Fairtrade Foundation and the Fairtrade Labelling Organisation (FLO), our case study reveals a moral economy of non- (or partial) recognition, which has a range of unintended consequences and paradoxical effects.     

中国区域性极端降水事件及人口经济暴露度研究

基于中国1960-2014年771个气象站的逐日降水资料,选取有效降水序列95百分位数作为极端降水阈值,将既定持续时间尺度和连续面积上超过阈值的降水事件定义为区域性极端降水事件。采用强度-面积-持续时间（Intensity-Area-Duration,IAD）法,根据极端降水事件空间和时间上的连续性特征,对不同持续时间的区域性极端降水事件演变趋势及暴露于极端降水事件下的人口和国内生产总值进行研究。结果表明:（1）相对强度最大的区域性极端降水事件主要集中在1960-1968、1991-1999和2006-2013年3个时段;（2）区域性极端降水事件最强中心主要分布在长江以南和东北地区,发生在北方的多为单日极端降水,南方多为持续多日的极端降水;（3）1960-2014年区域性极端降水事件影响面积有所增大,相对强度变化不明显;（4）暴露于极端降水事件影响区域内的人口和国内生产总值均呈显著增大趋势,暴露人口最多的年份在1983年,达到2408万人/d,暴露国内生产总值最多的年份在1998年,达到20亿元/d。      

Re-conceptualizing the Anthropocene: A call for collaboration

Since it was first proposed in 2000, the concept of the Anthropocene has evolved in breadth and diversely. The concept encapsulates the new and unprecedented planetary-scale changes resulting from societal transformations and has brought to the fore the social drivers of global change. The concept has revealed tensions between generalized interpretations of humanity’s contribution to global change, and interpretations that are historically, politically and culturally situated. It motivates deep ethical questions about the politics and economics of global change, including diverse interpretations of past causes and future possibilities. As such, more than other concepts, the Anthropocene concept has brought front-and-center epistemological divides between and within the natural and social sciences, and the humanities. It has also brought new opportunities for collaboration. Here we explore the potential and challenges of the concept to encourage integrative understandings of global change and sustainability. Based on bibliometric analysis and literature review, we discuss the now wide acceptance of the term, its interpretive flexibility, the emerging narratives as well as the debates the concept has inspired. We argue that without truly collaborative and integrative research, many of the critical exchanges around the concept are likely to perpetuate fragmented research agendas and to reinforce disciplinary boundaries. This means appreciating the strengths and limitations of different knowledge domains, approaches and perspectives, with the concept of the Anthropocene serving as a bridge, which we encourage researchers and others to cross. This calls for institutional arrangements that facilitate collaborative research, training, and action, yet also depends on more robust and sustained funding for such activities. To illustrate, we briefly discuss three overarching global change problems where novel types of collaborative research could make a difference: (1) Emergent properties of socioecological systems; (2) Urbanization and resource nexus; and (3) Systemic risks and tipping points. Creative tensions around the Anthropocene concept can help the research community to move toward new conceptual syntheses and integrative action-oriented approaches that are needed to producing useful knowledge commensurable with the challenges of global change and sustainability.

基于外部性理论的湿地退化成因分析及对策研究

基于生态经济学中的外部性原理,结合湿地生态系统的准公共物品属性、外部经济性、外部不经济性以及代际外部性等属性,分析湿地退化的成因.结果表明：湿地萎缩加剧、生态服务功能衰退主要是由于人类缺乏对湿地功能与效益的正确认识,以及不合理的利益分配机制导致的成本外溢现象,从事湿地保护的正外部性行为未得到应有的补偿,负外部性行为未付出应有的代价,并提出应建立因地制宜的多元化生态补偿机制.

福建省域工业空间结构研究——以福建省销售额前300家工业企业为例

依据地域经济系统理论,一个地域经济单元状态,可以从时序特征和空间结构特征进行表达,其存在状态受制于时空关联性。一定地域在特定时序发展阶段,必有与之相对应的空间结构特征;反之,一定的空间结构特征必然反映其特定的时序阶段。据此,诊断了福建省域工业系统的时空关联性特征,并提出了该省工业阶段性跃迁的对策与建议。     

全球化与新经济背景下的广州市空间结构

全球化与新经济对城市空间结构的形成和演变产生了深刻的影响。基于统计资料及实际调查,分析了广州城市空间结构的演化过程及格局。结果显示,广州城市演化表现出明显的阶段性,包括单中心增长模式、飞地发展模式、“二元”空间结构模式及融合多核心网络模式。现阶段处于二元空间结构模式的发展阶段,新城市区域与老城市区域在产业结构、人口结构、景观特征等方面存在明显的差异。这种城市空间形态结构的演变及格局,是全球化及新经济因素、体制因素、政策及城市规划因素等多种因素综合作用的结果。近年来,全球化与新经济对城市空间形态发展起着日益重要的作用。广州城市空间结构的分析对我国大都市空间结构研究具有重要的启示意义。     

流动人口分布与区域经济发展关系若干解释(1990、2000)

本文对我国1990、2000年间流动人口在东、中、西部和东部地区中环渤海、长江三角洲、珠江三角洲及福建三个亚区的分布变化以及这一分布变化与上述各地区各相关经济与非经济因素变化的关系进行了研究。研究发现,10年中流动人口东、中、西部分布变化与东、中、西部经济发展的变化高度一致;而10年中流动人口在东部地区环渤海、长江三角洲、珠江三角洲及福建这三个亚区层面的分布变化则与经济发展要素变化有一致的方面,也有不一致的方面。珠江三角洲及福建的经济增长带来了流动人口的大幅增长,除珠江三角洲劳动密集型企业众多外,这可能与该区域地方社会人文等文化本底所决定的经济发展制度及习俗有一定的相关性。
