Patterns of Changes to Woody Vegetation near Resettlement Sites in Semi-arid Northwestern Ethiopia

Communal rangelands provide diverse ecosystem services to millions of pastoralists and agro-pastoralists. Resettling destitute communities into hitherto uninhabited communal rangelands and forests, a common practice throughout Sub-Saharan Africa, is a threat to the sustainable use of range and forest land resources. In order to understand the effect of resettlement on a semi-arid woodland in northwestern Ethiopia, satellite imagery of 23 resettlement villages taken over a period of fourteen years, and woody vegetation floristic data for three old resettlements, three new resettlements, two refugee camps and one protected area were analyzed using ANOVA and canonical correspondence analysis (CCA). The normalized differential vegetation index (NDVI) and canopy cover around all village types decreased with disturbance gradients, while the magnitude of change varied according to the type of settlement. Limited canopy cover was observed in refugee camps and new resettlements, compared to old resettlements and protected areas. Woody vegetation height class showed a J shaped distribution in all sites except refugee camps (RC), indicating a decline in vegetation. CCA showed that variables like site type, altitude and disturbance gradient significantly affected the diversity of woody species at the different sites. Comparison of individual species responses to disturbances indicated that low fodder value invaders like Dichrostachys cinerea, and many Acacia species were increasing in proportion and coverage at the expense of some multipurpose species including Tamarindus indica, Diospyros mespiliformis, and Pterocarpus lucens. In the absence of regulated vegetation use, resettlements result in a decline in overall vegetation cover and a shift in floristic diversity in favor of invasive species.     

基于活力特征分析的城市安置社区公共空间研究——以苏州城区6个安置社区为例

由“散居”到“集居”,安置社区面临社会关系重建的巨大压力。基于公共空间活力内涵,采用AHP-模糊综合评价法,构建了城市安置社区公共空间活力评价模型,以苏州市6个安置社区为例,对3种安置模式的社区公共空间活力特征进行定量评价和比较。发现：① 不同安置模式的社区公共空间活力存在明显差异。尽管异地安置社区的公共空间的设施完备、类型多样,但是其公共空间的社会活力度最低。对于公共空间活力提升,社区公共空间背后的社会属性比其物质属性更为重要。②公共空间因子活力度与关注度存在不匹配现象。基于“社会-空间”辩证互动逻辑,提出安置社区公共空间活力营造策略： 对于今后安置社区,适宜“村内小集居+跨村大聚居”的安置模式,通过最大程度维系原有“熟人社区”群体的社会边界,提升公共空间活力,减轻社区社会关系重建的压力;对于现有安置社区,可根据公共空间因子活力度和关注度的匹配关系,划分公共空间改造的优先级,采用差别化的改造策略,提升公共空间活力及其改造资金的使用效率。     

南京棚户区改造的城市社会空间重构效应

中国2008年开始推进的城市棚户区改造运动,是一项针对城市住房困难群体的重要民生工程,也是有利于拉动投资与消费需求,推动新型城镇化建设的发展工程,深刻影响着城市社会空间的转型升级与分异重构.根据2008-2020年南京主城区434个棚户区改造前后的社会空间属性差异,在整体掌握南京棚户区改造时空特征的基础上,重点探讨棚户...     

转型期城市居住用地更新的空间加密化研究——广州市金花街改造再考

选择具有代表性的广州市金花街改造项目（1988~2003年）为案例研究对象,分析了政府主导下改造方案的调整过程和改造空间特征,探讨居民诉求和政府旧改政策对旧城空间的影响。研究表明：金花街居民的原地安置诉求和城市政府依此设计的以民生为导向的改造安排,乃是影响旧城空间的重要原因;在准市场化融资方式和福利化拆迁安置方式下,城市政府提出的有关提供公共服务设施、解决居民临时安置问题和让居民原地安置的要求,使改造规划多次提高改造容积率,以保持改造经济平衡;改造后的金花街在房屋和人口两个维度呈现空间加密化的态势,即存在原地安置房叠加融资商品房、原地安置居民叠加购房迁入居民的社会空间现象,金花街改造并未出现以外来中产人口大规模替代原住低收入人口为基本特征的绅士化过程。最后,从引入转让开发权和鼓励微改造两方面对当前广州的旧城改造提出政策建议。     

Adaptive Strategies to Displacement and Environmental Change Among the Kaiabi Indigenous People of the Brazilian Amazon

Environmental change, geographical displacement, and disputes over land and resources have increased around the world. This article focuses on strategies developed by the Kaiabi indigenous people to cope and adapt to environmental change after development-forced displacement and resettlement in the Brazilian Amazon. A mixed methods approach was adopted, combining ethnographic and quantitative methods. Semistructured interviews were performed among 214 individuals in a study on the dynamics of indigenous knowledge (IK) and natural resource management across three Kaiabi lands. We identified seven main coping and adaptive strategies developed by the displaced group: leadership and reciprocity networks, mobility, maintenance and innovation of native language, knowledge articulation, substitution of strategic resources, transmission across genders, and revitalizing diversity. These strategies have helped to enhance social–ecological resilience at different scales. Policies for resettlement and adaptation to environmental change must be developed with indigenous communities based on local knowledge and institutions.     

Rural Local Economic Development and Land Restitution in South Africa: The Case of Schmidtsdrift,Northern Cape

Local Economic Development is (LED) an activity of increasing importance in the developing world as globalisation produces new roles for local governments. As compared to a growing number of urban initiatives for LED, rural LED initiatives are relatively undeveloped. In this paper, the focus is upon South Africa, where the post‐apartheid government has sought to encourage both urban and rural LED initiatives. Programmes of land reform and restitution in South Africa result in the resettlement or return to the land of communities formerly dispossessed under apartheid. A critical element of planning for successful resettlement is the implementation of LED programmes. Schmidtsdrift in Northern Cape is examined as an example of participatory LED in a developing rural context. Rural LED in South Africa is distinguished by its focus upon poverty alleviation in the context of addressing the legacies of apartheid.     

全球化背景下封闭社区形成的影响因素与空间效应

随着经济全球化和西方新自由主义政策推行,封闭社区以其空间私有化、社会分异与隔离的特征成为一种特殊的全球现象。封闭社区对城市社会、政策和经济发展等方面具有重大影响。本文在对国内外研究成果总结的基础上,探讨封闭社区的性质、类型和形成的影响因素,并重点讨论封闭社区对城市空间发展与演变的影响。封闭社区具有物理空间封闭性、社会空间隔离性和文化空间契约性,是经济全球化与新自由主义政策、制度环境与历史文化变迁和多元主体共同作用的产物。在空间效应上,封闭社区影响着城市物质空间、社会空间和文化空间的塑造和演变,进而深刻影响城市空间演化与城市发展。最后,从城市政府和城市规划的角度讨论封闭社区的治理建议。     

Development,Land-use Change and Rural Resettlement Capacity: a case study of the Three Gorges Project,China

Resettlement of people displaced by dam projects is an important development issue. Land lost due to the Three Gorges reservoir inundation and the adjustment of land-use policy in China resulted in land-use changes, and impacted on the human carrying capacity of the land and the land availability for resettlement. The Chinese government has implemented a ‘development-oriented resettlement’ policy and a ‘near resettlement’ approach to relocating rural dwellers affected by the Three Gorges Project (TGP). Based on recent land-use survey and population data of the case study area and using GIS-based multi-criteria analysis in land-use planning, this study analyses the characteristics and changes of land use in both the inundation and resettlement areas. Undeveloped land is scarce in both areas. The non-flooded cultivated land is distributed mainly on steep slopes (over 25 degrees). There is a discrepancy between the amount of land required by those being resettled and what is available in the designated resettlement communities. This study suggests that resettlement should consider the human carrying capacity of the land and, from a community standpoint, sheds light on the interplay between land-use planning and resettlement, and provides constructive suggestions for TGP resettlement strategies.     

内城区户籍贫困空间剥夺式重构研究——基于南京10843份拆迁安置数据

采用南京内城区2001-2011 年期间10843 户贫困家庭的拆迁安置数据,探讨内城区户籍贫困空间格局及其重构特征。通过空间自相关与空间聚类等研究方法,对城市拆迁发生前内城区22 个街道的贫困家庭分布格局分析发现:① 样本贫困群体在街道尺度上社会经济属性相对均质,主要贫困属性因子的空间自相关性不强;② 内城区户籍贫困空间格局具有良好的历史延续性,总体上呈分散布局并遵循着自然渐进式的空间演化模式;③ 拆迁安置导致内城区贫困空间发生由中心至边缘、由分散到集中的重构,而且这种贫困空间边缘化过程具有强烈的不可逆性;④ 贫困家庭的物质居住条件通过拆迁安置得以改善,代价是因搬离内城而远离商业区、重点中小学、三甲医院和地铁站点等城市优质公共资源。内城区贫困空间剥夺式重构过程中,城市优势区位的丧失有可能导致贫困家庭的交通、就业与生活成本增加,向上流动机会减少。     

基于SNA的新型集中社区公共空间网络结构优化

公共空间并非“存在即合理”。公共空间网络结构效率折射出社会网络的重构能力、社会资本的建构强度、社会秩序的重塑能力。新型集中社区作为近年大量涌现的新型居住形态,正面临社会关系重构的巨大压力。本文运用社会学的网络分析法研究公共空间网络,并对苏州新型集中社区D的公共空间网络结构进行实证分析,其结论为：公共空间网络的关联度为0.216、中心势0.358、小世界值1.978,表明空间网络整体关联度不足,呈现出破碎化的特征;商业空间整合效应的发挥受到业态配置的影响;居民社会属性对空间网络结构特征造成一定影响。最后,基于“社会—空间”互动逻辑,以社会网络重构为导向,从集中安置模式、公共空间网络优化2个层面,提出新型集中社区有待进一步研究的方向,以期为当前及未来的集中社区规划建设和公共空间整体优化提供科学合理的依据。     

Damming China’s rivers to expand its cities: the urban livelihoods of rural people displaced by the Three Gorges Dam

Over the next two decades, China, the country with the world’s largest urban population, is orchestrating the urbanization of some 300 million rural people. In its National New-Type Urbanization Plan (2014) the State Council has outlined a range of strategies to grow its cities not least of which is rural-to-urban migration. This plan will have significant effects on other types of displacement, particularly, the forced displacement and resettlement of those living in the path of large dams. This paper reviews what is known about New-Type Urbanization Approach to Reservoir Resettlement. Then, based on a longitudinal study of 145 resettled households at the Three Gorges Dam, the livelihood effects of rural-to-urban resettlement are unpacked to provide lessons for its use in advancing urbanization. It finds that rural-to-urban resettlers have lower incomes than their urban-to-urban and rural-to-rural counterparts, and higher rates of food and income insecurity.     

广州河涌的自然社会构建与城市记忆

基于网络文本、访谈和照片评定等数据,本文采用NVivo分析方法对广州河涌案例展开分析,讨论了城市自然的社会建构与城市记忆之间的互动机制。研究发现,城市自然资源的功能随着社会经济条件变化而变化,并通过人的实践与社会系统彼此渗透、共同演化。具体来讲,以广州河涌为例,本文指出河涌的社会建构很大程度上反映了城市职能和物质形态的演变,反映了物质的利用方式及其与城市文化之间的关系;此外,城市居民与河涌的互动是文化生产的一种方式,在这个过程中,河涌是地方文化的物质承载者,也是维系地方感的重要物质载体;最后,河涌是城市居民产生记忆及其身体实践的重要物质场域,通过此类物理的沉淀,城市记忆才得以传承和保存下去。研究立足于物质地理学视角,强调了自然资源的社会建构过程,重新审视了人类与自然资源的互动关系及过程,进而反思城市发展与自然之间的处理方式,从实证角度回应了文化地理学从“唯物主义”到“文化表征”再回到“重返物质主义”这个轮回对“物质”和“文化”这两个核心概念的审视。从现实意义来讲,本文讨论了城市居民与城市自然之间的互动,为营造健康城市以及为城市再生产的发展思路提供了一定的参考价值。     

The Feminist Geographer as Killjoy: Excavating Gendered Urban Power Relations

In this article, I place Ahmed's notion of the feminist killjoy into conversation with feminist geography literature to explore possibilities and praxis in research endeavoring to illuminate uneven power relations and the moral orders that frame them. According to Ahmed, a feminist killjoy is one who exposes sexism, heterosexism, and racism, only to be criticized for disrupting happiness and social consent. Drawing on fieldwork on urban politics and development, I explore the implications—both promise and peril—of adopting feminist killjoy research subjectivities, emphasizing the important role of affect. I suggest that when feminist researchers direct killjoy research not just at mainstream institutions but also at progressive endeavors, they risk being construed as double killjoys who disrupt supposed joy and solidarity within progressive politics.     

Beyond Gentrification: Mobilizing Communities and Claiming Space

During the 20th century, neighborhood change and the displacement of low-income residents from their homes has occurred in a variety of ways from the demolition of entire areas to more recent revitalization efforts emphasizing the building of community and new governance structures. In this paper, I argue two interrelated points. First, whereas economic displacement of low-income people from their homes and neighborhoods is one effect of neighborhood revitalization initiatives, there is a wider set of factors that constitutes the marginalization, displacement, and exclusion of certain population groups from effectively making claims on neighborhood space. Second, in an era of neoliberalization, whereby civil society is expected to play a larger role in neighborhood governance and the provision of social welfare, the formation and activities of neighborhood-based communities, and their relation to state and market forces, have become increasingly important factors to examine. In this article, I address these areas of inquiry through a case study of a neighborhood revitalization initiative in Chattanooga, Tennessee that has been under way since 1998.     

The Commodification of Resource Consent in New Zealand1

One outcome of the Resource Management Act 1991, especially the provisions of s.94, is liberalised public notification of resource consent applications. A market for consent has emerged, in which applicants financially compensate local communities as a way of securing public support for development proposals. Consent purchasing, however, raises diliemnas for regulatory planners and social equity concerns for local communities.     

Bio-gentrification: vulnerability bio-value chains in gentrifying neighbourhoods†

In this paper, I develop the concept of “bio-gentrification” as a way to broaden critical theoretical debates on the relationship between gentrification and “social mixing” policies. Bio-gentrification weds urban Marxist political economic insights to the neo-Foucauldian notion of biopower. The former stresses spatial tactics of removal and displacement and value generated through land and property. The latter assesses a wider terrain of spatial tactics, their relationship to knowledge produced about humans as living beings, and their alignment with capitalist urbanization. The Vancouver example illuminates how social mixing “truths” and practices to which they are tied generate value by naturalizing human insecurity in situ and transforming the biological existence of disadvantaged peoples into raw material for profit through a process that can be conceptualized as a “vulnerability bio-value chain.” Bio-gentrification refers to the tension between removal and embedding of disadvantaged peoples and points to the need for a bio-gentrification politics to confront this dynamic.     

Entrepreneurial city and the restructuring of urban space in Shanghai Expo

ABSTRACT

This study examines the restructuring of urban space brought about by Shanghai Expo. The focus is on how the municipal government strategically makes use of this mega-event program to proactively implement two entrepreneurial spatial policies, namely economic restructuring and population decentralization. Specifically, it critically investigates the omnipotent government’s policies in terms of industrial relocation and residential resettlement leading up to the Shanghai Expo. Shanghai’s entrepreneurial city building, at the metropolitan level, has long been associated with the optimization of spatial structure. The empirical findings reveal that the negotiations involved in relocating enterprises were tougher when they took place within the state system, as compared to those between the government and foreign or private sectors. At the same time, social groups remained excluded from decision-making processes for resettlement, and there was a downscaling of governance, which contributed to improved efficiency of the resettlement work. The Shanghai municipal government was key to the restructuring and entrepreneurial city building, engaging, on the one hand, in negotiations on spatial relocation with central state-owned enterprises (SOEs) at the level of the central government and mobilizing, on the other hand, lower-tier government authorities to deliver the resettlement plan. This paper argues that the development of the entrepreneurial city in Shanghai depends essentially on the way local government implemented the policy and that an integrated approach is significant to attaining the goals and objectives.     

Lacan on urban development and national identity in a global city: Integrated Resorts in Singapore

Lacanian psychoanalysis has been used in film, literature and other areas of social thought, but rarely in the domain of urban studies and human/cultural geography. Following its introduction by urban planners Michael Gunder and Jean Hillier, I apply the theory of the four discourses and the mirror stage of development to Singapore's urban development of the two Integrated Resorts at Marina Bay and Sentosa. The decision to allow gambling and build casinos was a contentious one and provides a point of departure for insight into the identity issues and planning decision making processes in Singapore. I critically analyse the rhetoric of the public debate from 2004–2005 to draw conclusions about the government's self‐perception of Singapore as a city‐state and the manifestation of this identity through the creation of cosmopolitan spaces as an attempt to project that identity onto its citizens. The aim of Lacanian psychoanalysis is to provide an understanding and recognition by analysis to enable a change of signifiers, values and ideology among the masters and the subjects to better represent the true needs and wants of the community. This reflective position enables a movement toward postcolonial urban studies and planning.     

跨界的城市增长--以江阴经济开发区靖江园区为例

近年来,长江三角洲的一些城市出现了资源耗竭或紧缺的问题．由此引发了城市间合作共建工业区和开发区的新现象。因为在此类工业园区中也往往伴随着行政管理权力在合作城市之间的转移．所以这种城市合作的创新可以被视作跨界的城市增长。本研究在增长联盟的理论视角下对江阴经济开发区靖江园区的跨界城市增长进行了研究．深入探讨了各级地方政府、企业、地方媒体和农民四种参与者在联盟形成中的作用和互动。研究在理论上证实了城市尺度以上增长联盟的存在．丰富了增长联盟理论、在对中国城市政治的研究上．研究发现地方政府和企业结成的增长联盟已经在中国城市中出现。同时．农民结成的反增长联盟也在不断壮大,这主要是由于土地征用、缺乏就业机会和不合理的拆迁安置造成的。江阴-靖江的经验与问题也将为其他城市的跨界发展提供借鉴。     

新兴城市类单位社区生活圈的建构路径与特征差异——以深圳为例

有关单位制度与生活圈的讨论多数集中在具有较长计划经济历史与较强国有经济色彩的城市,但是实际上一些新兴城市也存在单位制度实践或类似制度实践.以深圳为例,论文在分析了深圳城市建设与发展过程中的单位制度力量后,选取7个具有单位社区特征的社区,对比商品房社区与城中村社区,从空间行为和社会关系等维度描绘了这些社区居民生活圈的特征...
