Youth Mobility and Territorial Disparities: An Analysis of Urban and Rural Barcelona

Travel behavior of the present generation of youths is being increasingly explored due to their relevance in shaping future accessibility needs and mobility habits. The present study offers an original perspective on this topic by identifying territorial disparities that emerge in youth mobility patterns in rural and urban areas. Unlike most previous research, we propose taking a global view on mobility by analyzing all trip purposes and transportation modes. This is conducted by analyzing a comprehensive mobility survey in the Barcelona Metropolitan Region, which provides data on mobility engagement, trip purposes, modal split, travel times and territorial differences. In general, youngsters account for larger daily travel times than older adults, present a higher attachment to public transportation and walk less on a daily basis. These differences are enhanced in rural territories, where while older adults overcome accessibility issues with higher use of the private vehicle, youngsters are more likely to invest larger travel times on transit.     

The Three American Wests

In the twenty-first century, there are three American Wests, which cut across cultural, political, physical, and economic boundaries. Parts of the West are booming, building homes, and adding population; others are legally off limits to such development; and much of the West has been bypassed by such development and growth. These are called here the Booming West, Protected West, and Bypassed West. Maps of climate, political boundaries, ethnic and racial identities, or presidential voting patterns do not match these three Wests. Each West has a different relationship to the others and might see them as threats or opportunities, and each West can be expected to grow in different areas at the expense of other Wests. The boundaries between the three Wests could be important locations; sharp transitions can exist between Wests, perhaps nowhere more so than where a fast growing metro area abuts a national park or forest boundary. Finally, the effects of climate change cut across the three Wests and have different implications for their future. Continued population growth will further emphasize the boundaries between each of the three Wests and raise the stakes for their control.     

黄淮海地区乡村人—地—业协调发展格局与机制

乡村在社会中占有重要地位,但乡村衰败目前已成为世界性问题,因此,乡村振兴需破解乡村病问题。现有乡村研究主要关注乡村单一系统、乡村转型或乡村特定问题的研究,对乡村系统自身、乡村各子系统之间关系及其驱动乡村发展逻辑的研究则显匮乏。基于黄淮海地区县域数据,选取乡村人—地—业3个子系统,利用耦合协调度模型刻画了乡村内部系统耦合协调度的空间格局,并对人—地—业驱动乡村发展的内在逻辑进行了探讨。结果发现：① 黄淮海地区大部分县域乡村人—地—业发展处于高水平耦合阶段,在空间格局上形成了4条明显的高值轴带,且乡村系统发展水平呈逐年上升趋势。② 黄淮海地区乡村耦合协调水平整体较高,但大部分处于勉强协调或初级协调阶段,耦合协调水平较高的县域主要集中在经济较发达地区。③ 黄淮海地区乡村耦合协同关系可分为低协调水平—土地发展领先型、中协调水平—人口发展领先型和高协调水平—人业发展引领型3种类型,其中产业在黄淮海地区乡村协调发展中至关重要。④ 乡村人—地—业的协调发展可有效激活“四力”,为乡村可持续发展奠定了基础。本研究为理解乡村系统自身、破解乡村问题及实现乡村可持续发展提供了参考。     

“How Much Does Property Cost Up There?”: Exploring the Relationship between Women,Sustainable Farming,and Rural Gentrification in the US

Using in-depth interviews with women engaged in sustainable farming in the western United States, this project explores an unanticipated finding: migration from an urban area to rural “Prairie County” was necessary for these farmers to secure farm land and sustain their farming operations. This article interrogates the role of migration in women’s access to farmland as both an economic and cultural phenomenon. My findings highlight the necessity of migration for women’s participation in sustainable farming and suggest that women’s success in sustainable farming may align with the processes of rural gentrification, by which cultural and economic in-migrants amplify their social privilege and transform the values and economy of rural communities. This project, then, situates gender as a key structure to understanding both the classed dynamics of sustainable agriculture and rural gentrification.     

Faith and Doubt in an American Working Landscape: The Importance of Scale,Work, and Place in Rural Development Planning

The term “working landscape” (WL) is increasingly used by American planners and policy makers to describe the rural places and livelihoods they aim to shape. This paper draws from a mixed-methods study of WL language as a collective action frame in the state of Vermont, where WL has been formalized into policy. Natural resource leaders and professionals share a common definition of WL that is supported by four key beliefs. However, interviews conducted in two representative farming communities suggest that landuse practitioners have not adopted WL language, and in some cases are skeptical of its meaning. The analysis explores potential explanations for the failure of the WL collective action frame to resonate across scales. The paper argues for a bottom-up planning approach that produces working landscapes policies that allow for diverse forms of work and accommodate the specificities of place.     

Studying Resource-Dependent Communities Through a Social-Ecological Lens? Examining Complementarity with Existing Research Traditions in Canada

This article explores the suitability of Ostrom and colleagues' social-ecological systems framework (SESF) for the study of resource-dependent communities in Canada. Through a broad literature about resource-dependent communities in Canada, three main approaches are identified, named staples research, rural development, and sustainability studies. Each of these research traditions is analyzed with regards to a common set of criteria – focus, scale, methods, treatment of institutions, and treatment of environmental dimensions. Research in each category is compared and contrasted with the SESF approach, to identify areas of overlap and divergence. Results indicate that the SESF is unlikely to provide additional benefit in terms of in-depth of social analysis, however, it does provide a unique contribution in terms of its coupled approach to conceiving social and ecological systems and its ability to operationalize these relationships through structured variables.     

西北贫困地区乡村类型识别与振兴途径研究

乡村振兴战略是新时期我国推进城乡融合发展的重要举措。贫困地区既是脱贫攻坚的主战场,又是乡村振兴的重点区域。如何科学识别村落类型,分类推进典型区域乡村振兴发展,对于破解农村发展不平衡不充分问题具有重要的现实意义。本文解析了乡村地域系统发展理论,阐释了城乡融合发展理论,剖析了村域空间结构格局演变和城乡要素结构功能优化重组;构建了西北干旱贫困地区乡村振兴村落类型识别体系,从乡村主体、产业发展、人居环境、资源禀赋4个子系统进行逐级分类判断,识别乡村主导类型,结合专家征询分析与村落特征,将乡村振兴村落类型识别为集聚提升类、三产融合类、城郊融合类、特色保护类、搬迁撤并类,结合不同乡村振兴模式提出了相应地发展路径,以期为乡村振兴提供理论依据与决策参考。
