This paper addresses the impact of land use patterns associated with compact population on the costs of provision and maintenance of urban public services for local entities, controlling for other factors. The aim is to develop an econometric analysis using a panel data set of municipalities of the Spanish Mediterranean area and Madrid in the period 2006–2014. The estimations derived from the study confirm one main hypothesis and indicate that compact population impacts positively on the decrease of municipal costs of urban public services. This study suggests that municipal planning instruments of local entities could contribute to efficiently manage their budgets, as well as orients public policy in terms of its local land use decision-making.  相似文献

江苏省土地利用程度与区域生态效率关系研究   总被引:1,自引:0,他引:1  
研究目的:以江苏省为例,研究土地利用程度对区域生态效率的影响机制,提出合理利用土地、提高区域生态效率的政策建议。研究方法:将相关概念进行操作化定义后,基于江苏1990—2007年的数据,建立方程进行回归分析。研究结果:随着土地利用程度的不断加强,江苏省的生态效率随之提高,二者呈显著正相关,相关系数为0.683;土地生态系统的生态服务价值却随着土地利用程度的加强而下降,二者呈显著负相关,相关系数为0.911。研究结论:合理的土地利用程度,能够确保土地生态系统持续地提供各类生态产品和服务,进而促进区域生态效率的提高,反之,土地的粗放式利用使土地利用类型比例失衡,再加之缺乏维系土地生态系统可持续性的措施,会导致土地生态系统服务功能的减弱,并最终制约区域生态效率的提高。  相似文献

The relationships of regional integration, land tenure and land use have all received substantial previous attention. Nonetheless, existing theoretical frameworks tend to presume ideal types of land tenure in understanding the impacts of regional integration on change in institutions and land use. We therefore evaluate the evolutionary theory of land rights (ETLR) for the case of Madre de Dios, Peru. This is a useful case since tenure for agricultural lands is private individual as the ETLR theorizes, but other characteristics, such as the presence of forest extractivism, depart from the assumptions of the ETLR. We pursue a multi-step analysis of key relationships of the ETLR, focusing particularly on the linkages between highway paving as an indicator of regional integration, titling as a measure of tenure formality, multiple indicators of land market engagement, and land uses with diverse ramifications for ecological sustainability. Findings for the different steps partially support the ETLR for the case of Madre de Dios. Disconfirmation however sometimes occurs due to geographic accidents rather than due to truly contrasting findings. We conclude by discussing the need to identify characteristics of empirical cases that do and do not fit the expectations of theories in order to better evaluate the applicability of theory for analysis and policy.  相似文献

中国区域生态用地分类的研究进展   总被引:2,自引:0,他引:2       下载免费PDF全文
研究目的:总结和梳理中国区域生态用地分类的相关研究文献,分析中国区域生态用地分类的特点,提出中国区域生态用地的分类体系,为中国区域生态用地的利用和管理提供科学依据。研究方法:文献资料法、归纳分析法和比较分析法。研究结果:当前中国对生态用地的内涵缺乏统一的界定,现有的土地利用分类体系对土地的生态属性考虑不足,导致生态用地分类缺乏统一的标准以及生态用地难以得到有效保护。研究结论:(1)应从"泛生态功能论"的视角来界定区域生态用地的内涵,将耕地等以生产功能为主,同时具有较为重要的生态功能的土地纳入生态用地范畴,但应排除建设用地范围内的绿化用地;(2)基础性生态用地是维护区域生态环境安全最重要的自然本底,为了加强对基础性生态用地保护和管理的针对性,在分类体系中应突出基础性生态用地;(3)区域生态用地可采用三级分类,一级类可分为基础性生态用地、保全性生态用地和辅助性生态用地三大类;(4)为有利于对现有土地利用现状调查数据的应用,建议生态用地分类体系中三级分类的名称设置和内涵尽量与现行的《土地利用现状分类》国家标准相衔接。  相似文献

Summary

For more than seven decades, several Indian states have used the plot reconstitution technique in managing urban land development. Recently, Kerala, a small southern state, has experimented with this technique for the first time in a scheme in Trichur. The Trichur experience is unique in that it incorporates significant innovations over a somewhat similar method of land readjustment which is widely practiced in the Asian‐Pacific region. Formulated for complete cost‐recovery, the Trichur project incorporates the active cooperation of the landowners and officials, and is a time‐bound programme to complete all land development and building construction works within six years of the finalization of the scheme proposals.

This paper attempts to explore the use of this innovative means of land development in Trichur with a view to assessing the potentiality and constraints in its use, and identifying critical areas where further refinements would be desirable. Based on fieldwork in the state and intensive interviews, the paper finds the Trichur experience to be of great importance as a viable strategy of urban land development and management. The paper concludes with some recommendations on legal and institutional aspects, and stresses the need for refinements in the scheme preparation and information dissemination for transferability and wider application of the technique.  相似文献

The growing demand for a wide range of private and public goods and services from a finite land resource is increasingly challenging for planners at local, regional, national and international scales. The Scottish Government's development of a Land Use Strategy has given salience to resolving conflicts and enhancing synergies in land use. In Scotland, the poorest quality farmland is often designated for nature and landscape conservation and the highest quality farmland often protected for food production. This means that many of the competitive pressures on land are experienced in what we term the ‘squeezed middle’. The paper identifies the multiple (and not exclusively economic) drivers of land use choices and, through an ecosystem services lens, explores three particular areas of land use conflict. These are (i) the continued high level of public support for farming, which has done little to address the problem of low farm incomes; (ii) the pressure to increase woodland planting on farm (and other) land; and (iii) conflicts associated with intensive game management, especially on sporting estates. Using the Scottish situation as an example, the heterogeneity of land use pressures means that there is a danger of the principles of the Land Use Strategy becoming lost in translation from national policy to practical land use decision-making. The appropriate scale for delivery of integrated ecosystem services may therefore be more local than current pilot projects, and may require more active participation of land managers. It may also require policy instruments that are more flexible in adapting to the local context, including payments for ecosystem services.  相似文献

China's Sloping Land Conversion Program (SLCP) pays millions of farmers to convert cropland in upper watersheds to tree plantations. It is considered one of the world's largest payments for ecosystem services (PES) scheme for its reliance on financial incentives. This paper examines the outcomes of the SLCP by way of a case study from the Yangliu watershed in Yunnan province. It focuses on the notions of justice embedded in state policy and held by villagers and local state officials in order to understand the observed outcomes in terms of people's participation in the implementation of the SLCP, land use changes and livelihood effects. Villagers, local state officials, and state policy share a primary concern about distributive justice despite significant differences in their specific notions. The shared concern underlies the villagers’ positive reactions to the SLCP, which among other factors, have led to the intended expansion of tree plantations and a livelihood transition in Yangliu since 2003. The insights from Yangliu suggest the need to consider justice for a fuller understanding of the dynamics and outcomes of the SLCP and other PES schemes worldwide as the notions of justice applied by the involved actors may influence land use and livelihood dynamics in addition to the other factors considered in research this far.  相似文献

This article explains how recreational subdivisions convert large tracts of rural land in the USA into ‘potential vacation homesites’. Much subdivision has occurred in areas where land use regulations are weak or non-existent. All too often developers have implemented an operational framework without a master plan, have not adhered to local environmental constraints, and failed to provide the most basic services needed for human habitation. Many of these so-called ‘planned new communities’ qualify as neither communities nor planned and end up as ghost subdivisions with vast acreages of unused, vacant land marked by an elaborate network of bladed roads. Specific developmental guidelines are suggested to assist governmental officials in reducing the negative impact associated with the premature subdivision of land years prior to its expected use.  相似文献

The allocation of land resources is a crucial issue in sustainable urban development, but it is subject to the vagaries of public governance. By using the prosecution of corrupt local leaders as the shock event, and exploring the data on sacked officials and land transfers in prefecture-level cities in China from 2006 to 2016, we analyse the changes in the supply of land in response to the ousting of key local officials for corruption. The estimations derived through the identification strategy of the DID framework show that both the volume and value of land sales dropped significantly after the local officials’ ousting, with the value of total land sales reacting to a much greater extent. We also found the reduction of land supply was mainly from commercial and residential land but a greater supply of land for public use following the local leaders’ ousting, accompanied with an increase in the level of marketisation in the supply of land and a reduction in cheap transfers of industrial land. In addition, the heterogeneity of the effect across the rank and type of official was investigated, and the long-term persistence of this effect was confirmed. By showing that anti-corruption measures have a persistent disciplinary effect on officials’ subsequent land supply strategy, this paper underscores that the quality of public governance profoundly influences the functioning of the land market.  相似文献

Policies and planning processes related to land use play an important role in maintaining and developing ecosystem services. The incorporation of ecosystem services into local plans is considered an indicator of the plan’s capacity to implement strategic action. This study provides a national overview of the incorporation of the ecosystem service concept in current municipal comprehensive plans in Sweden and explores the actions taken by three municipalities in Stockholm County to implement the ecosystem service concept in practice. A multi-method design was employed including a qualitative content analysis of 231 municipal comprehensive plans, a statistical analysis analyzing temporal changes from 2005 – 2017, and dialogue meetings with municipal practitioners from the three municipalities. We divided the level of integration to four categories, A (Advanced) - D (Not included). Overall, the integration of the ecosystem service concept has significantly increased in municipal comprehensive plans during the last decade. At national level, 23% of municipalities have explicitly mentioned ecosystem services, and within Stockholm County, 42%. The dialogue meetings with municipal practitioners revealed that the municipalities were at different stages of implementing the ecosystem service concept, with diverse actions being implemented for advancing practice. These included capacity building, participatory processes and development of thematic plans and operational documents. To support the future implementation of the ecosystem service concept from vision to action, both local and national initiatives are needed.  相似文献

Shortfalls in global food production, coupled with the growing visibility of climate change's disruptive effects, have underlined for many observers the importance of devoting rural lands to their ‘optimal’ use, where they can make maximal contributions to the global imperatives of feeding the human population and maintaining vital environmental services. In this context observers have endorsed rural land use planning as a way to insure that, at least in theory, lands get devoted to their best uses. In practice, land use planning in the developing world has resembled ‘organized anarchy’. Small landholders with insecure land tenure, overseas investors seeking large land deals, NGOs representing indigenous peoples, government officials, and staff from international environmental NGOs and multilateral organizations have come together in strategic action fields to struggle over and sometimes negotiate land use plans for contested landscapes. These plans represent a strategic, spatially explicit response to the climate change–biodiversity–food security crisis.  相似文献
