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.     

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.     

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.     

Perceptions of Land Tenure Security in Rural China: The Impact of Land Reallocations and Certification

Abstract

Tenure security is commonly recognized as an important factor in stimulating long-term investments in land. Recent studies suggest that a distinction between legal, actual and perceived tenure security needs to be made in analyzing tenure security. This study discusses the relationships between legal, actual and perceived land tenure security in rural China, and empirically examines the impact of actual on perceived land tenure security by applying Probit models to household and village survey data collected in four provinces. Using household expectations about the absence of land reallocations within the next five years as the dependent variable, we find that tenure security is positively affected by the possession of land certificates in villages that periodically reallocated land but not in villages that did not do so. The estimated impact is larger for land certificates issued in the new round of land certification than for land certificates that were issued earlier.     

国土空间规划中水源涵养功能生态保护红线备选区的识别

水源涵养功能重要性是生态保护红线划分工作中重要的评价指标之一。通过对以往生态系统水源涵养功能区划分的指标及其区域导向的系统梳理,在进一步明晰国土空间规划中水源涵养功能生态保护红线区域指向的基础上,按照国土空间规划关于“三区三线”自下而上试划的要求,探讨了水源涵养重要性生态保护红线划分及其评价的改进方法。选取中国典型喀斯特区域六盘水市作为研究案例区,分别用环保部2015版与2017版《生态保护红线划定技术指南》中的模型法、NPP法以及本研究提出的改进方法,对六盘水市水源涵养功能生态保护红线进行了试划。对比三种方法的划定结果可以看出,改进方法因评价数据精度的提高减少了《生态保护红线划定技术指南》方法的区域损失,提高了区域判别的精准性,可望为国土空间规划中生态保护红线的划定提供科学依据。     

国土空间规划中城镇空间和城镇开发边界的划定

在2016年国务院印发的《省级空间规划试点方案》所提出的“开展基础评价”和“绘制规划底图”两项主要任务中,城镇适宜性的评价与城镇空间、城镇开发边界的划定属于核心内容,同时也是一项具有较强探索性的工作。以国家对国土空间规划的基本设想为依据,对城镇空间和城镇开发边界的概念和内涵、空间关系、相关规则进行深入探讨,确定了城镇适宜性评价与城镇空间、城镇开发边界划定的主要思路和技术路线。结合福建省空间规划的案例,分析了城镇适宜性评价与城镇空间、城镇开发边界划定的过程、方法和结果。不同于以往各部门开展的空间性规划,城镇空间和城镇开发边界的划定建立在资源环境承载能力和国土空间开发适宜性的基础评价之上,这使得城镇开发建设活动的空间布局在资源环境本底方面得到合理保障,城镇空间和城镇开发边界的划定也有了较为科学、客观的依据。此外,把基础底图的研制与城镇发展潜能、城镇开发指向的评估,以及开发建设的规模管控、空间管控、开发强度管控系统地整合起来,使得规划底图的随意性得到了较好的控制。实践表明,本文的思路和技术方法是合理可行的,这一尝试可为空间规划理论和方法体系的完善提供参考。
