Rural residential land transition (RRLT) dominates rural land use transition. Therefore, analysing the laws of transition and differentiation of land use is not only the basis for the differential management of rural residential areas but key to the sustainable use of rural land. This study constructs a conceptual model of RRLT using multi-period remote sensing monitoring data based on a comprehensive index method, ArcGIS, and FRAGSTATS landscape pattern analysis, among others. It also analyses the characteristics of the transition extent, transition trend, transition morphology, and transition intensity of rural residential land in the Beijing-Tianjin-Hebei (BTH) region from 1980 to 2018. The results show that, from a vertical comparison of long time series, the transition extent is characterised by a process of ‘slow growth—expanding start—fast expansion—slowing down’; the transition trend is characterised by an increase in the amount of cultivated land occupied by rural residential land, followed by a large number of rural residential land is reclaimed as cultivated land; the transition morphology is characterised by an increase in mean patch size and degree of irregularity, as well as aggregation; and the transition intensity is characterised by fluctuations in the process of ‘small-scale reduction—small-scale growth—substantial growth—small-scale growth and reduction’. A horizontal comparison of counties in the BTH region reveals a long-lasting and active growth trend in transition extent and transition intensity in the Beijing-Tianjin region, and a gradually slowing trend in the areas around the region. The transition morphology features of the northwest Hebei region are more prominent, and show that the scale of rural settlements is small, the plaques fragmented and irregular, and the layout more scattered. The BTH region should formulate a differentiated transition direction for rural residential areas based on the different functional areas, and play into the agglomeration, scale, and synergy effects of urban agglomerations. It should also coordinate and improve the human–land relationship in rural areas, and construct an orderly and densely distributed pattern of urban and rural spatial development with a reasonable layout and complementary functions.  相似文献

Large-scale land acquisitions (LSLAs) are increasing in Ghana amid a weak legal and regulatory framework. This paper explores the impacts of this phenomenon on farmer innovations under recurrent environmental changes. Using a case study of z, an indigenous innovative farming practice, the paper makes two interrelated arguments. Firstly, it shows that the pervasive enclosures coerced by the Ghanaian state undermine how indigenous knowledge could be proactively deployed for climate risk management. Secondly, LSLAs produce a social barrier to climate change adaptation, as they lead to heightened uncertainty and apprehension among farmers, which affects decisions on climate risk management. More specifically, land expropriation is an example of how adaptation could be hindered by governance, institutions, and policy at the extra-local scale, including not only existing land use laws, but also the constitutional guarantee of private property. The evidence supporting these arguments come from survey data on 619 plots, 70 in-depth interviews, village-level transect walks, and participant observations. Overall, the paper contributes to emerging debates at the interface of land use policy, climate justice, and sustainable adaptation. Theoretically, it also contributes to understanding State-society relations, as well as the political economy of eminent domain, often justified through discourses of “public benefits.”  相似文献

Over the last four decades, the loss of agricultural land has been observed in Egypt at high rates. However, the highest rates of losses have occurred since the January 25th revolution in 2011. Greater Cairo (GC), which is the largest metropolitan in Egypt, has witnessed a massive loss of agricultural land since the 2011 revolution. However, until now, no study or official report has revealed the volume of agricultural land losses in this region. This study quantifies agricultural land losses around the GC using Landsat satellite images from 2010 and 2018. Supervised classification was performed using the maximum likelihood algorithm in QGIS software. A post-classification comparison method was applied to detect the land use/land cover changes between the classified images; then, the loss of agricultural land was quantified using Arc GIS software. Visualizations of the gains and losses in agricultural land and the spatial trends of agricultural land losses were created using TerrSet software. The results show that 9600 ha of agricultural land were converted to urban use during 2010–2018, which means that the annual rate of agricultural land loss has tripled and now reaches approximately 1200 ha per year. Decay of executive authority, rapid population growth, real estate market speculation and fragmentation of agricultural land were the main driving factors of agricultural land losses during this period. The results of this research may help decision makers understand the current high rate of agricultural land loss. Hence, appropriate strategies may be adopted to prevent future losses of this valuable land.  相似文献

The Republic of Ireland possesses a land market that is constrained by minimal sales each year, less than 1%. In an effort to capitalise on milk quota abolition and to increase dairy production, a suite of tax incentives has recently been introduced in the Republic of Ireland to encourage land mobility and long-term leasing among Irish dairy farmers. Using Irish Farm Accountancy Database Network (FADN) data from 2011–2017 to examine this, a Heckman sample selection model explores two aspects; (i) the factors that influence a farmer’s decision to rent, or continue renting, land and (ii) the profitability of dairy farmers renting in land. We find self-selection into the rental market is driven by farm traits that include a high level of hired labour, the presence of a successor, intensive farming practices and dairy discussion group membership. The results show that rental agreements assist farms in achieving economies of scale. The findings provide evidence to support government intervention such as tax incentives for renting out land and knowledge sharing discussion groups.  相似文献

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.  相似文献

泸县农村宅基地有偿使用制度改革效果评价   总被引:1,自引:0,他引:1  
[目的]宅基地有偿使用制度研究有利于推进宅基地制度改革,缓解无偿无限期带来的土地超占乱占和闲置问题。[方法]文章运用层次分析法和模糊综合评价法对2016年和2018年泸县农村宅基地有偿使用制度改革政策效果进行评价。[结果]政策的开展能有效推进村民自治建设进程,但政策的实施要注重公开透明性;有偿使用政策能有效缓解一户多宅、低效闲置、超占乱占等土地浪费现象实现土地的节约集约利用;政策的实施能有效地改善基础设施和农村面貌,但对泸县生产方式转变、新业态发展、农户生活水平提升影响力较小;总体来看农户对有偿使用政策满意度和支持度较高。[结论]针对当前有偿使用制度改革,该文认为宅基地有偿使用制度改革还应该完善有偿使用费收取管理政策,增强政策执行透明度;注重基层队伍建设,实现有偿使用费保值增值;合理选择安置模式,发展农村新业态;加强宅基地有偿使用与有偿退出的高效联动,推进宅基地制度改革进程。  相似文献

为了确保农村土地的正常流转,要求建立明晰的产权结构,因而也就产生了土地确权的要求。本文旨在通过描述目前农村土地确权流转的背景及现状,运用马克思的资源配置理论中的土地产权理论和级差地租理论对土地确权流转过程进行理论分析,并且针对现实中存在的问题,相应的从健全农地流转市场、加大金融保险支持力度、抑制"非粮化"、确保农民主体地位等方面提出了对策建议。  相似文献

农民土地权益是农村土地制度改革情况的直接反映。狭义上的农民土地权益主要包括土地生存权和土地发展权。基于"产权结构—要素流动"的理论分析模型,改革开放以来,中国农村土地政策变革下的农民土地权益变迁过程划分为三个阶段。这三个阶段在本质上也就是土地生存权和土地发展权逐步实现的过程。  相似文献

土地规模经营与农业先进技术的应用是推动我国农业可持续增长的重要因素。基于农民在经济和社会方面的异质性特点,通过分析江苏泗阳县X镇的案例,研究发现:将土地流转与农民专业合作社结合的模式,不仅可以缓解土地分散经营对农业规模效益的不利影响,而且可以使农民在互相信任的环境中通过"干中学"、接受集中培训等方式推广农业生产技术。因此,政府应推动土地流转并引导农民建立合作组织。  相似文献
