New roles for farming in a differentiated countryside: the Portuguese example

Throughout Europe, the role of farming as the private provider of public goods and services increasingly valuated by society is today generally acknowledged. Furthermore, in the turn towards rural development concerns, multifunctionality as an attribute of rural space has emerged, justifying the territorial approach of farming. The situation facing the multifunctionality demand is nevertheless not the same in all European regions, which by all means is getting strengthened in the transition towards post-productivism. In some regions, there is a productivist orientation and production has a dominant economic role, while others will need to be supported on other functions to survive economically and socially, or may be best suited to environmental functions alone. The vocation of the rural territories is different, and thus also the functions they are able to support. This paper discusses the concept of multifunctionality of the rural areas, and defines a possible methodological approach towards the identification of the different types of rural areas in Europe, based on the identification of ideal types, through the analysis of selected indicators. The empirical application has been developed for the Portuguese Ministry of Agriculture, aiming at assessing the differentiated characteristics and dynamics of the Portuguese rural territory. Analyzing data from 1990 and 2000, at municipal level, three dimensions have been considered: the land cover, the agricultural sector and the rural community. Combining the three analyses, it was possible to identify different vocations of the rural space, and the role that farming could have in the future for the multifunctionality of the territory. Accordingly, the municipalities have been grouped in types, pre-defined as ideal types. This was a first attempt to understand the differentiation of the rural territory in Portugal. For decision-making it should be further developed. It nevertheless shows that there is clear differentiation concerning the possible landscape functions to be developed between regions and a possible way to assess. It also shows that a territorial approach to agriculture may be the key for the maintenance of the sector in many areas where production by itself, as it has been know until now, may be severely threatened.     

The cradle of the city: the environmental imprint of Brussels and its hinterland in the High Middle Ages

As a popular assumption, the cities are considered to exert a major impact on their hinterland. In fact, little is known about this imprint on the earlier period. This paper will thus try to delineate as far as possible urban and rural contributions to the imprint by using a cause and effect analysis. The paper argues that the birth of second generation cities like Brussels is the result of a demographic and economic process occurring in the rural environment. Above all in a second phase, once the process of human concentration within the city initiated and the town became a market center and a consumer power, rural developments changed under the urban imprint: at that moment the city imposed a certain spatial structure on the rural system with intensive and high profitability cultures replacing extensive practices.     

城市中农村迁移家庭的劳动供给行为分析

城市中农村迁移家庭的劳动供给行为一直是发展经济学研究的主题之一.本文建立了中国城市中农村迁移家庭的劳动参与模型和工作时间模型,用于分析城市中农村迁移家庭的劳动供给行为.研究结果表明:农村迁移劳动力劳动参与率高,工作时间长,主要在非正规部门就业；农村迁移家庭中女性和男性的教育收益率分别为3.71％和4.97％,且随着受教育年限的提高,男性工作时间将明显增加；身体健康不仅有助于女性劳动参与率的提高,而且有助于女性和男性工作时间的增加；随着年龄的增长,个体倾向于减少工作时间；但随着经验的增长,个体倾向于增加工作时间；女性工作时间的工资弹性和收入弹性分别为-0.261 3和-0.073 3,而男性工作时间的工资弹性为-0.3443,说明女性和男性的工作时间曲线均向右下倾斜；女性劳动参与的工资弹性为0.539 5,远高于工作时间的工资弹性.因此,政府通过发展农村教育和医疗服务,适当提高城市最低工资标准,将能够有效地促进农村迁移家庭就业水平和收入水平的提高.     

Application of the Eco-Industrial concept to community environmantal management

This study is aimed at studying the feasibility of applying the Eco-Industrial concept to community environmental management and then investigating factors and appropriate means. In-depth interviewing of scholars and authorities and surveying of five sample communities representing the four different regions in Thailand is carried out to search for the feasibility of applying the concept. The results show that it is feasible, especially in rural areas, where dependence on the local resources and the community members in doing activities in the communities in accordance with the ecological context still exists. Factors and conditions involved in applying the concept include analysis of resources, participation of the people, community leaders, formulation of community development plans, good communication, sharing of knowledge, and provision of appropriate support to create network of communities. The appropriate means of applying the concept to community environmental management entails promoting involvement in the part of the local people and sustainability in the cooperation, with appropriate channels of communication and under the guidance of the leaders, who are the community’s central figures with the determination and ability to motivate and navigate the people in the community. Importantly, there must be analysis on the economic, social, environmental, and health benefits resulting from such application.     

Environmental justice and the expanding geography of wind power conflicts

Wind power is expanding globally. Simultaneously, a growing number of conflicts against large-scale wind farms are emerging in multiple locations around the world. As these processes occur, new questions arise on how electricity from wind is being generated, how such energy is flowing within societies, and how these production-flows are being shaped by specific power structures. The present paper explores the expanding geography of wind energy conflicts by analyzing 20 case studies from across the Americas, Africa, Asia and Europe. Based on the Environmental Justice Atlas database, it reflects on how land pressures and patterns of uneven development emerge as two features of the current expansion of wind farms. Following a relational analysis, these patterns are examined to interpret the plural instances of opposition emerging throughout the rural spaces of the world. The article argues that previously unexplored forms of collective action are expanding the scope and content of the “wind energy debate”. In addition to the claims of “landscape” and “wildlife protection” addressed by the existing literature, this study sheds light on the rural/peripheral contexts where opposition emerges through the defense of indigenous territories, local livelihoods and communal development projects. The study contends that these “emerging storylines” embrace an environmental justice perspective when challenging the socially unequal and geographically uneven patterns reproduced by the ecological modernization paradigm. From this lens, cases of local opposition are not interpreted as selfish forces blocking a low-carbon transition, but instead, are understood as political instances that enable a wider discussion about the ways such transition should take place.     

Drivers of change in mountain farming in Slovakia: from socialist collectivisation to the Common Agricultural Policy

The transformations in Slovak agriculture from the 1950s to the present day, considering both the generic (National and EU) and site-specific (local) drivers of landscape change, were analysed in five mountain study areas in the country. An interdisciplinary approach included analysis of population trends, evaluation of land use and landscape change combined with exploration of the perceptions of local stakeholders and results of previous biodiversity studies. The generic processes active from the 1950s to 1970s were critical for all study areas with impacts lasting right up until the present day. Agricultural collectivisation, agricultural intensification and land abandonment had negative effects in all study areas. However, the precise impacts on the landscape were different in the different study areas due to site-specific attributes (e.g. population trends, geographic localisation and local attitudes and opportunities), and these played a decisive role in determining the trajectory of change. Regional contrasts in rural development between these territories have increased in the last two decades, also due to the imperfect preconditions of governmental support. The recent Common Agricultural Policy developments are focused on maintenance of intensive large-scale farming rather than direct enhancement of agro-biodiversity and rural development at the local scale. In this context, local, site-specific attributes can and must form an essential part of rural development plans, to meet the demands for management of the diversity of agricultural mountain landscapes and facilitate the multifunctional role of agriculture.     

A model of ozone production in urban plumes

A model of rural smogs and urban plumes introduced into rural smog is developed. The single day variation of level of reactive species including ozone in rural smog in the eastern United States is simulated by mathematical modelling. Rural air masses are modelled as though they were outdoor smog chamber systems of low inital contaminant concentration to which small additional injections of contaminants, representing rural emissions, are made throughout the day. Rural smogs containing urban plumes are modelled as though they were outdoor inflatable smog chambers to which relatively large amounts of pollution material are added in the early minutes after sunrise and which are continuously diluted with material from chambers simulating rural smog. The urban plume model is specifically intended to simulate the photochemistry of parcels of air which sweep over relatively isolated cities in the eastern United States.The model runs suggest that the observed lack of urban plumes downwind of small cities is due to dilution. Additionally, the model suggests that the concentrations of both ozone and ozone precursors in rural smog have a significant effect on ozone production in urban plumes.     

基于灰色关联和主成分分析的农村建设用地集约利用评价——以江苏省为例

基于农村集体建设用地集约利用的内涵,构建了一套评价农村集体建设用地利用集约度的指标体系,并以江苏省苏南、苏中、苏北的12个行政村为例,采用灰色关联与主成分分析方法对各行政村集体建设用地利用的集约度进行了对比分析。分析结果表明:苏南地区的农村集体建设用地利用的集约度较高,而位于苏北地区的农村集体建设用地利用的集约度则相对较低,苏中地区在两者之间,整体上与江苏省区域经济的发展水平相符;从近郊与远郊的农村集体建设用地集约利用水平来看,两种评价方法测算的集约度虽有所差异,但两种方法对于近远郊的排序是基本一致的,呈现的趋势是近郊农村集体建设用地利用集约度高于远郊的。研究表明,两种方法所得的农村集体建设用地利用的集约度大致相似,在近郊远郊空间分布以及苏南、苏中、苏北的区域差异所呈现出的规律性,可为制定促进区域农村经济发展和提高农村建设用地的集约利用水平等相关的宏观政策提供参考依据。     

新时期城镇化进程中的农民工问题与对策

在新时期城镇化进程中。农民工的流动具有新的特点：农民工基数大、集中度高。造成流向偏差进而引发“大城市病”,面临组织化程度低、社会地位被“边缘化”,遭受经济贡献与利益分事上的失衡．并且新生代农民工和返航农民工正从农民工群体内部分化出来。在这种情况下。应增强中小城市的吸引力．加强城乡劳动力市场一体化建设。为进城农民工提供必要的公共服务和社会保障,加强职业技能培训。合理引导农民工“返航”潮流。帮助新生代农民工融入城市．防止“拉美陷阱”的出现。

中国城市CO_2排放数据集研究——基于中国高空间分辨率网格数据

城市CO_2排放数据的可获取性和质量直接影响了城市碳排放的科学研究、低碳战略制定及公众对于城市低碳发展的监督和参与。数据缺乏和多源数据的不确定性大是中国城市CO_2排放核算和低碳城市规划面临的重要问题和挑战,而这些问题同时也导致中国低碳城市研究水平参差不齐。本研究使用自下而上建立的中国高空间分辨率网格数据(空间分辨率为1km),采用统一数据源和规范化、标准化数据处理方法,建立中国城市CO_2排放数据集,供研究者和决策者参考。城市CO_2排放计算借鉴国际上较为成熟和应用广泛的核算方法,包括范围1和范围2排放。以北京、上海、天津、重庆和广州5个典型城市的能源统计数据自上而下计算其CO_2排放作为参考水平,检验数据集的数值质量,结果显示5个城市的数据差异均不超过10%。中国城市CO_2排放整体呈现北方大于南方,东部高于中部和西部的空间格局。CO_2排放量较高的城市大多处于华北、东北以及华东沿海地区,西部地区城市CO_2排放量则较低。城市CO_2排放8个部门(工业能源、工业过程、农业、服务业、城镇生活、农村生活、交通、范围2排放)之间的相关性中,城镇生活和交通排放的相关性最高,并且呈现显著性(p0.001),工业过程排放和服务业排放的相关性最弱且没有显著性。基于中国高空间分辨率网格数据的中国城市CO_2排放数据集的不断完善和发展,为中国城市CO_2排放研究奠定了重要的数据基础,为城市CO_2排放横向比较和对标工作提供了重要依据。     

中国农村生活能源消费的空间格局变化

本文以1996年、2000年2、003年、2006年中国29省(市、区)(上海市和西藏数据缺失)农村生活能源为研究对象,应用因子分析、聚类分析和回归分析,借助SPSS和ArcGIS软件,对中国农村生活能源消费空间格局及空间格局变化的影响因素进行分析探讨。结果表明:在1996-2006年间,我国农村生活能源消费水平的空间格局基本形成以华北-西南地区为轴线向两边逐渐递减的态势,且趋势愈加明显;华北地区和西南地区高水平特点不断强化;轴线两侧区域差异不断扩大的同时,各自区域内的一致性趋向明显。经过经济发展水平、人口分布与能源消费水平的叠加显示:西北地区属于贫困型低消费地区,华北和西南地区属于人口规模型高消费地区,东南沿海地区属于高效型低消费地区。回归分析结果表明:影响农村生活能源消费空间格局变化的首要因素为能源消费强度,其次是能源消费增长速度和能源消费结构,其中前两者为负向影响,后者为正向影响。     

不同情景下的人口迁移及其对农村土地利用影响研究——以重庆市为例

随着我国工业化和城镇化的深入推进，农村人口迁移趋势愈演愈烈。人口迁移导致的劳动力投入减少对农村土地利用存在威胁。运用情景模拟的方法，研究了不同情景下的人口迁移及其对耕地撂荒和宅基地闲置的威胁。研究表明：(1)重庆市未来人口迁移由4部分构成：都市区农村人口向城区迁移；都市区外农村人口向都市区集聚；都市区外农村人口向区域性中心城市和城镇集中；市外人口回流；(2)未来10 a，重庆市总人口流量46445~48481万，而对土地利用有影响的人口流量约36445~42481万；（3）预计到2020年，重庆市存在撂荒威胁的耕地约412~480万hm2；（4）预计到2020年，重庆市农村宅基地闲置潜力为597~611万hm2。建议改革限制农村耕地流转的政策，避免耕地撂荒；探索“复垦+流转”的农村闲置宅基地处置模式     

农村低保救助水平的评估

农村最低生活保障制度在中国范围内已经实现制度覆盖,自2007年制度全面推行以来,由于各省市财政对农村低保救助力度强弱差异,导致了对农村低保对象的救助程度存在很大的差异性.但由于这种差异性受很多因素如价格指数等经济指标的影响,存在着不可比性.笔者通过引入农村低保救助力度系数和生活救助系数剔除这种差异性,从横向和纵向的视角对中国现行农村低保制度的救助水平进行了评估.评估的结果发现,各地的农村低保标准相差较大,经济发达地区剔除经济发展水平等因素以后,保障标准仍然要高于经济相对落后中西部农村地区(上海市除外).所以,建议这部分省市的民政部门要根据本地的经济发展水平来制定当地农村低保名义标准,从而保证当地农村低保居民享受到的实际福利至少不应该低于低保名义标准.

我国城乡环保一体化的制度建构:理念、原则与路径

近年来,我国"城市环境趋向好转,农村环境不断恶化"这种城乡环境二元趋势的凸现,提出了城乡环保一体化的客观要求."城市中心主义"环境法制以及我国农民实质自由的严重匮乏是我国产生城乡环境二元趋势的根本原因.一些地方所采取的仅仅局限于环保领域的城乡环保一体化措施,并不能从根本上扭转城乡环境二元趋势.城乡环保一体化实践需要以更为全面的制度建构为基础.城乡环保一体化的制度建构应树立理性、人本、自由等基本理念,应坚持整体推进、科学建构、多元参与等基本原则.城乡环保一体化的制度建构路径,首先是消除对农民的各种制度性歧视,实现城乡居民的权利平等;其次,在推动地方民主与法治建设,推进司法体制改革、建立司法审查制度的基础上,健全与完善农民权利实现的保障机制,保证农民的各项权利最终成为"可实际行使"的权利.最后,还要建立适应农村环境保护要求的环境法制.     

Problems of Rural Migrant Workers and Policies in the New Period of Urbanization

The huge migration of rural workers has new characteristics such as the bad order, high degree of concentration, low level of collective action, marginality in social status, unfair treatment, difficult integration of the new generation, and the new return trend of rural migrants, which causes ＇urban diseases＇ in China. Countermeasures should be taken to develop medium-sized and small cities, integrate the labor market of the city and countryside, provide necessary public services, social security and vocational training, guide the rural migrant workers to return rationally, and help the new generation live in harmony with urban residents.     

Problems of Rural Migrant Workers and Policies in the New Period of Urbanization

The migration of rural migrant workers has new characteristics and results in problems in China's “urban diseases” caused by the bad order of migration with a huge number and a high degree of concentration, low level of collective action, marginality in social status, unfair treatment, difficult integration of the new generation, and new return trend of rural migrants. Countermeasures should be taken to develop medium-sized and small cities, integrate the labor market of the city and countryside, provide necessary public services and social security, provide vocational training, guide the rural migrant workers to return rationally, and help the new generation live in harmony with urban residents.     

The association between rural–urban migration flows and urban air quality in China

In light of the rapid urbanization of the world’s population over the past decades, there is a growing concern about the environmental impacts of urban population growth. Rural–urban migration is a particularly important component of the urbanization process in developing countries and is often considered to be detrimental to urban environmental conditions. However, few studies have explicitly examined the presumed negative impacts of in-migration on the natural environment of cities. The continuously increasing volume of rural–urban labor migration in China since the early 1980s has formed the largest population flow in world history. This study links the existing literature on population–environment and urbanization–environment interactions by empirically assessing the relationship between rural–urban migration and urban air conditions in China. A two-period (2004 and 2010) longitudinal dataset for the 113 key environmental protection cities of China was constructed based on multiple data sources. We applied the STIRPAT equation using conventional and spatial panel regression models to examine whether rural–urban migration flows were associated with air pollution in cities. Results show a strong negative association of in-migration with urban air quality even after controlling for the effects of other population, affluence, and technology factors. Findings from this research can contribute to a better understanding of the environmental consequences of rural–urban migration in China, with broader implications for sustainable development research and policies.     

苏中地区农村就业结构转换态势与机制分析

伴随着农村经济社会的巨大变迁，农村劳动力就业结构也发生了深刻变化。江苏苏中地区作为乡镇企业带动型发展的典型地区，其农村就业结构转换的态势在东部沿海地区具有代表性。该地区农村就业结构转换的总体态势是：第一产业就业比重不断降低，第二、三产业就业比重明显上升；农业剩余劳动力转移的主要渠道是第二产业就业；农村就业结构转换，是工业化、区域经济发展及其结构变动综合作用的结果。市场经济环境为农村剩余劳动力转移提供了基础平台，工业化是农村就业结构转换的原动力，城市与农村经济结构调整是农村就业结构转换的直接推动力。产业收入比较利益是促使农业剩余劳动力流动的根本动力。而与之相适应的政策措施是其顺利实现的重要保障。
