We hypothesize that as the "global city" label becomes ever more central to a city's identity, local urban government policy increasingly supports those economic sectors that city leaders see as being congruent with the global and increasingly undermines sectors that serve primarily local markets. Through an in-depth study of small-scale manufacturers in the Williamsburg neighborhood of Brooklyn, in New York City, we examine the extent to which and the ways in which local policy undermines otherwise healthy locally oriented businesses. We find that the City's assumption that urban manufacturing is a dying breed becomes a self-fulfilling prophecy, largely via the City's own treatment of its manufacturing businesses. Through a lack of enforcement of zoning codes, zoning variances and rezoning initiatives, and more quotidian policies of harassment over noise and other quality of life complaints, the City is making it more difficult to do business for small-scale manufacturers. These policies then create a conventional wisdom that sees the City as a difficult place to start and grow a business.  相似文献

In Freetown, the capital city of Sierra Leone, rapid urbanisation combined with the lingering impacts of the devastating decade long civil war (1991–2002), has left large portions of the population without reliable work or income. One response to this has been an increase in urban and peri-urban agriculture (UPA) which provides participants with employment, income and food security. According to local government estimates, women comprise around 80% of Freetown’s UPA community, and many women rely totally on UPA as a livelihood strategy to feed and support their households. This article focuses on the experiences of these women farmers, and in doing so sheds new light on their vital contribution to Freetown’s growing UPA community who are not thus far represented in published literature. Globally, women are also underrepresented in UPA literature, and as a result their distinct challenges are not well understood. Reporting on field-based research, this article identifies challenges facing Freetown’s women farmers, including land tenure, access to clean water, limited capital for purchasing tools, fertilisers, and pesticides, and difficult relationships with government, NGOs, and other farmers. The manner in which these challenges manifest themselves in relation to women farmers, as distinct from their male counterparts, are identified, and opportunities for Freetown’s UPA community to support and empower women farmers will be highlighted.  相似文献

Over the past few decades, cities and city regions have become the core of the global economy. Regional governments are increasingly drafting city development policies and implementing them through various visioning documents with the aim of making cities more global, networked and competitive. Welfarist governments especially in the global South are becoming increasingly entrepreneurial, and in the process poor citizens are getting pushed to the margins, evicted from their land and relocated to city fringes. Hyderabad in India provides an interesting illustration of neoliberal development trends in which poor local farmers are forced off their land to make way for a ‘world‐class’ knowledge enclave, popularly known as Cyberabad. This paper examines the policies and processes by which the regional government has sought to brand Hyderabad as a world‐class information technology destination and to restructure and reimagine it as a key node in a network of ‘globally connected cities’ of the world. It also considers the making of Cyberabad in terms of splintering urbanism, which is often understood as a defining feature of contemporary neoliberal urban processes.  相似文献

Fluctuating global commodity prices affect the livelihoods of millions of tropical farmers worldwide. In recent years, systemic oversupply of many tropical agricultural products, grown in countries such as Indonesia, has meant that agricultural incomes have continuously fallen below subsistence levels. Within an increasingly open global trade regime, along with the limited ability of governments to protect domestic farm prices, quality-informed product differentiation appears to offer an escape route from the trap of low commodity prices. However, ownership and governance of quality constructions are fundamental to determining who benefits from such differentiation. This paper examines the use of geographical identities as a specific tool for value-adding in agricultural produce, presenting the case of specialty coffee production in South Sulawesi, Indonesia. The potential for producer-driven geographical indications compete with corporate-driven quality constructions, where the latter are able to appropriate place-related quality associations by using trademarks, vertical integration and tightly coordinated supply chain controls. An emergent politic of quality governance and ownership in global commodity chains reveals the highly restricted institutional terrain within which growers of specialty coffee might attempt to retain a higher share of the economic rent associated with quality production.  相似文献

Ongoing urbanisation makes cities a key focus for global environmental change (GEC) research, creating an imperative for a new, city-scale, research agenda. The vulnerability of urban populations to the multiple stresses of GEC lies at the core of overlapping domains of knowledge that could be better integrated in advancing research. The urban development, global change and disasters literatures are fragmented and reveal fundamental cleavages over the role that government could play in mitigating vulnerability to multiple threats and challenges. Important empirical gaps exist, especially on cities of the South. While there are significant knowledge gaps and numerous tensions within and between schools of thought, this overview suggests useful entry points for framing an invigorated research agenda on urban GEC.  相似文献

Farmers struggle to afford farmland because competing land uses raise prices higher than what farmers earn, especially in small-scale and sustainable agriculture. Farmers often depend on an intimate partner’s income or labor to access land, yet few studies investigate sexual relationships in farmland access. I interrogate how sexuality shapes land access for small-scale agriculture through participant observation and interviews with 25 queer farmers in New England. I find that queer farmers’ sexual identities and relationships influence where they farm, who they live and work with, how they afford the land, and how they learn to farm. I argue that finding land, labor, credit, and knowledge are intertwined, heteronormative processes of capital accumulation shaped by racism and sexism. Queer farmers’ experiences navigating heteronormativity suggest the relevance of sexuality to land conservation and food justice, limits of organizing land access through sexual relationships, and alternatives to the “family farm.”  相似文献

全球土地覆被时空变化与中国贡献   总被引:4,自引:0,他引:4  
李广东 《地理学报》2022,77(2):353-368
20世纪下半叶以来全球土地覆被发生了剧烈变化,人类活动对土地覆被变化的影响成为“人类世”最为显著的特征之一。科学评估全球土地覆被变化的时空过程和新态势,分析中国在其中扮演的角色和地位并提出优化路径,成为中国在可持续发展领域应对全球百年未有之大变局的核心任务之一。本文基于多源土地覆盖数据,运用地理空间分析方法定量刻画了全球土地覆被变化的时空演化过程,从景观尺度分析了地类间的转化关系以及全球“变绿”和森林覆盖度的变化趋势,揭示了中国对全球土地覆被时空变化的贡献。结果表明,1992—2015年全球土地覆被经历了显著变化,全球土地覆被变化度在南美洲中部、撒哈拉以南的非洲、中亚、东南亚和东亚等地形成显著的热点区。中国森林覆盖率从1990年的12.98%增至2020年的23.34%,湿地面积增长1908 km2,为维护全球生态安全贡献了力量,同时在城市用地增长、草地和其他用地减少等方面也有一定的限制作用。与全球其他国家不同,中国城市扩张占用耕地面积居全球第一位,高达7.3万km2。1999—2019年全球叶面积指数存在全球性的显著提高趋势。中国以仅占全球6.6%的植被面积,贡献了全球20%左右的叶面积增加量,引领了全球“变绿”过程。1990—2020年全球森林覆盖度变化呈现出空间集聚性。中国森林面积增长62.84万km2居全球前列,其中西南林区和秦巴山区是林地增长的主要区域,长三角、粤港澳大湾区和内蒙古东部部分地区是森林覆盖度降低的主要区域。中国未来应进一步提升经济社会发展与生态保护的均衡协调度,持续推进美丽中国建设,为全球生态安全和可持续发展贡献更大力量和更多经验。  相似文献

The article examines an alternative food network evolution in the post-communist context in Czechia in general and farm shop developments in particular. The study is based on semi-structured interviews with farm shopkeepers operating in Czechia. The results revealed that the development of the farm shop network was significantly shaped by the communist past of the country. While consumers’ demand for quality food contributed to the initiation of developments in local food movements such as farm shops in Czechia, the inconvenient structure of the farming sector, comprising a limited number of small-scale farmers, hindered the development. Although the farm shops usually operate as middlemen by reselling goods produced by a range of farmers, farm shopkeepers expressed significant awareness of the sustainability principles of the local food concept and dissociated themselves from unethical practices of large retailers. Nevertheless, the author finds that the local concept is used in a flexible manner to meet customers’ demands. Despite obstacles faced by farmers when developing their own farm shops, there is significant potential in ‘Czech-type’ farm shops operating solely as retailers. However, the author concludes that the threat of the diversion from the sustainability principles of the local food concept should not be neglected.  相似文献

In this paper, we outline a framework to study what we have termed “Predatory Cities”, using the artificial offshore island of The Pearl in Qatar as a case study. By focusing on the nexus between urbanisation and resources, we will argue that the master-planning of new cities in the booming global South implies both the access and cheap exploitation of a set of, on the one hand, intangible and, on the other hand, tangible resources that exceed the traditional boundaries. Our point of departure is that the cheap appropriation and exploitation of alien architecture images and resource networks for the making of new, master-planned cities has become a necessary, but highly unsustainable, strategy to survive an increasingly competitive global offering of new destinations.  相似文献

利用投入产出分析法,在测算出国家层面的各产业GVC分工地位指数的基础上,引入东北三省内的地区和产业差异因素,估算出东北三省工业产业的全球价值链分工地位。研究发现,整体上东北三省采矿业等基础工业贸易增值量较大,但存在严重的产能过剩和低端锁定威胁;而其制造工业在全球价值链中的分工地位较低,对外贸易中表现出较为明显的比较劣势,并且这一劣势还存在恶化倾向。就各省来看,基础工业方面,辽宁省在采矿业上的比较劣势相对较小,黑龙江省在采矿业上存在更为严重的产能过剩和低端锁定风险,而在制造业上吉林省的比较劣势较大。因此,东北三省要实现全球价值链分工地位提升和产业结构升级,就需要转变传统的产业发展和外贸理念,加强创新能力建设,将高新信息技术与传统工业生产相结合,发展新型工业化模式,在借鉴国外有益经验的基础上,走创新驱动的集约化发展道路。  相似文献

Tourism is widely acknowledged as a key economic sector that has the potential to contribute to national and local development and, more specifically, serve as a mechanism to promote poverty alleviation and pro-poor development within a particular locality. In countries of the global South, nature-based tourism initiatives can make a meaningful impact on the livelihoods of the poor, in particular the subsistence based rural poor. Taking two examples in KwaZulu-Natal Province, South Africa, where small-scale tourism initiatives were developed recently in response to existing natural attractions in the context of coping with local economic crises, this paper broadly assesses the modest benefits to date, as well as drawbacks, in improving conditions of life.  相似文献

Explicit notions of “communities”, as key actors in conservation and development projects across the Global South, are common. Narratives about “indigenous people” or “forest-dependent communities” in forest conservation programmes prevail, portraying a picture of “communities” as homogeneous and harmonious entities. In this study, we unfold “communities” as a construct with an empirical example of a community-based forest protection project, Northern Cambodia. Based on qualitative interviews, field observations and document analysis, we examine the “community” construct in terms of establishment of boundaries, geographical composition and social coherence. We not only find that the establishment of forest “community” boundaries are dominated by powerful external actors rather than the “community members” themselves, but that the spatial composition of “communities” is complex, and affects the ability of local people to benefit from the project. We also find that the studied “communities” show low levels of social coherence and mainly consist of migrant farmers, as opposed to common policy narratives. Taking these inconsistencies into account, we discuss implications of constructing “communities” for the success of forest conservation projects, and argue in favour of more discursive and political analyses to better understand, acknowledge and adapt to existing and changing conditions in present and prospective project locations.  相似文献

Food security and sustainable agricultural development are the hot issues of scientific research, especially after the population affected by hunger surprisingly increased in 2016. Long-lasting and recurrent famines caused by natural disasters and wars have afflicted Ethiopia. Unlike Ethiopia, which is still struggling to achieve food self-sufficiency, China managed to quickly become food self-sufficient at a rapid speed, despite the fact that it also faced the same challenges of famine over the last century. In the backdrop of differing environmental and socio-political challenges the two countries face, comparing the similarities and differences between the two countries will yield important lessons and insights for Ethiopia to follow to achieve food self-sufficiency. Here, the progress towards food security in Ethiopia and China is presented to quantitatively compare the gap of agricultural production between both countries. We found that food production in Ethiopia is heavily constrained by drought, soil degradation, climate change, out-dated agricultural production technologies, and poverty. According to these challenges, we examined corresponding responses in China to propose solutions for achieving food self-sufficiency in Ethiopia, given the realities of its unique national situation.  相似文献

The global fisheries sector has undergone both rapid industrialization and considerable resource depletion. Unlike fisheries in the Northern Hemisphere, the Indonesian (and indeed Southeast Asian) sector is still largely dominated by small-scale producers, who are partially embedded within a subsistence economy. Changes in the nature of production and livelihoods in the fisheries sector appear similar to those in land-based agriculture but have received far less attention in the literature and demand further analysis given the distinct characteristics of the natural resource base. Using national datasets complemented by insights from a two-month period of fieldwork in South Sulawesi, this paper presents the process of capital intensification underpinning national fisheries growth and how it is transforming small-scale production systems. Despite increasing market integration, we found that smallholders have persisted across coastal production systems to an even stronger degree than land-based agriculture. We suggest some reasons why this is so. However, we also observed evidence of internal class differentiation within coastal communities. Such differentiation, combined with resource degradation and depletion, exposes the poorest in the community to enhanced livelihood vulnerability.  相似文献
