Riverside settlement in the Lower Badur Bawah area, precisely along the deli river in Hamdan village, Medan Maimoon sub-district , are one of the slum settlements being unorganized and densely ...populatade and the disposal of household waste water is not in place which makes this area prone to slum. Therefore, it is necessary to revitalize the area with land consolidation method in order to create a healthy and comfortable encironmental area in accordance with the social, economic, and cultural conditions of the surrounding community but do not forget the regulations that apply in the city of Medan. This research was conducted by conducting interviews with stakeholders and field observations by observing the behavior and activities of the residents of Badur bawah to produce a physical desription of the exixting settlements. Based on the results of observations, it was found that the characteristics of residential residents showed the orientation of the building back to the river, the lack of sewerage and the lack of public space and open space areas. The solution to the existing problems through consolidation of regional land by providing decent housing in accordance with the needs and income of the population and utilizing the river border as a open space that can be used as an area of social activity between residents to strengthen a sense of togetherness so that a sense of protecting, maintaining security and evironmental comfort, especially the cleanliness of the Deli river.
•The values of land fragmentation indicators were analysed in the context of effectiveness of agricultural production.•The positive effects of land consolidation persist forty years after the ...completion of farmland merging.•The assessment of the effectiveness of land consolidation projects should be carried out several decades after completion.•Land consolidation slows down land abandonment.
The high cost of implementing land consolidation projects (LCPs) justifies investigation of the question about the duration of economic effects of farmland merging. The assessment of economic effectiveness of LCP can be an essential argument in budgeting proceedings and in discussion of the importance of land relocation in the sustainable development of rural areas.
The main aim of this research was to verify the hypothesis of persistence of favourable basic parameters of land fragmentation (LF) and other factors affecting the efficiency of agricultural production that are still observed even several decades after LC. The aim was also to confirm that the parameters of LF within merged area are still much more favourable than those in neighbouring areas that have never been subjected to LC. The additional goal was to determine the scale and intensity of changes in LF that took place after farmland merging, and to estimate the influence of LC to farmland abandonment by analysing the intensity of secondary forest succession. The research was focused on the Jabłonka commune located in the southern Poland.
The results demonstrated the long-lasting effects of farmland merging, which are still evident even 40 years after the project has been completed. This is the most evident regarding the average plot size, road accessibility and land fragmentation indicators, which are calculated based on the area of the land parcel. Additionally, within the merged village the lowest level of land abandonment was observed, which was indicated by analysis of the areas covered by secondary forest succession and afforestation processes within formerly agriculturally areas. The results clearly indicated a multi-generational and positive impact of LCP on the development and functioning of rural areas.
The choice of a cadastral municipality for agricultural land management by land consolidation is a difficult task. It is very important that giving priority to certain cadastral municipalities for ...arranging agricultural land by land consolidation is done in a correct and objective way, ie that the initiation of land consolidation projects is not done spontaneously, but where the effects of land consolidation would be greatest. Methods of multicriteria optimization can help the decision maker to apply a mathematical model to reach a solution, ie to the cadastral municipality which should be given priority for starting consolidation projects. Precisely in this paper, it will be presented how the methods of multicriteria optimization lead to a solution, on the example of the Municipality of Indjija, Serbia. The ultimate goal of the research is to use a defined model to determine which cadastral municipality should be given priority for initiating and implementing a land consolidation project.
Agricultural production in China is crucial for socioeconomic development and food security. Land consolidation has been regarded as an important way to maintain food security and is highly valued by ...the Chinese government. However, whether productivity improvements can be achieved through land consolidation is not yet clear. To address this, we propose a straightforward method to assess agricultural productivity changes using remote-sensing data. The normalized difference vegetation index (NDVI) is used to represent yield, as its changes correlate significantly with yield changes. The analysis uses a Moderate Resolution Imaging Spectroradiometer NDVI time series covering a period of 13 years (2001–2013) at a spatial resolution of 250m and data on projects completed in 2006 and 2007. Control sites near the projects are used to eliminate the influence of other factors. The results show that 62.90% and 58.34% of projects in 2006 and 2007, respectfully, were effective at improving productivity, whereas 56.51% and 52.56%, respectfully, effectively stabilized productivity. Generally speaking, 78.67% of projects in 2006 and 78.32% of those in 2007 proved effective at either improving or stabilizing productivity; however, only 40.56% and 34.34%, respectfully, were effective at doing both. Furthermore, it should be noted that areas with effective productivity improvements mainly benefitted from growth in the cropping area and that the annual yield per unit area on project areas decreased within a few years after consolidation. The lack of effectiveness may be caused by problems of engineering, construction, and subsequent management. Governments must thus consider new consolidation projects comprehensively and cautiously before launching them.
This paper explores key issues associated with integrated consolidation and allocation of rural–urban construction land (ICARUCL) in China. Based on a critical review of the literature and analysis ...of selected case studies, we identify barriers to effective ICARUCL implementation, which result principally from shortcomings in governance at the central and local levels. A framework for more effective governmental functions, aimed at addressing the challenges associated with the ICARUCL process, is then developed. We argue that better integration of government functions is required, in order to address such concerns as widely divergent socio-economic development levels within metropolitan regions and diverse desires and needs of relevant stakeholders. Key areas of concern regarding effectiveness of the ICARUCL implementation process are the external institutional environment, allocation of public goods among stakeholders, and overall organization and coordination.
Ecological transformation is inevitable in development of land consolidation (LC) in China. An appropriate approach for assessing ecological environmental quality (EEQ) is fundamental for the ...analysis of LC efficiency. However, previous studies generally rely on statistical data or land use data, and the objectivity of these data and research periods are generally limited at the project scale. Based on the remote sensing data 6 years before and after LC, this study developed the RS-based theoretical research framework, provided a contrastive analysis between Remote Sensing Ecological Index (RSEI) and Ecological Index (EI) and expanded spatio-temporal pattern study to assess EEQ in a typical land consolidation project area (LCPA) of China, with the application of RSEI method. Results suggested that RSEI and EI showed strong comparability in the ecological sense, and RSEI can reflect the changes in EEQ in LCPA more effectively than EI. Wetness and greenness indicators had positive effects on EEQ promotion, while heat and dryness indicators had negative effects, and the effect of dryness indicator was more significant than that of other indicators. Before, during, and after LC, EEQ decreased first, increased later, and decreased overall, with the characteristics of degenerating during the construction period, improving during the restoration period, as well as degenerating in the overall process. LC caused persistent disturbance to EEQ, but there was a lag for restoration for more than 5 years. Prediction indicated that the selected indicators were the key indicators of EEQ, among which wetness and greenness were essential for EEQ improvement. This study provides certain theoretical guidance and method reference for the scientific, objective, direct, and long-term comprehensive monitoring and assessment of EEQ at the project scale.

Cultivated land consolidation (CLC) is essential for ensuring rural development and for optimizing national territory arrangement in China. The investment and implementation for CLC have been ...basically led by governments in China. And the introduction of social organization into CLC investment implementation is a significant experiment in CLC investment implementation models under new conditions of China, it is also an important supplement to traditional land consolidation models and is conducive to innovating land consolidation investment model and improving capital efficiency. Taking Suixi County in Guangdong province as a study area, this paper explores the investment implementation models and paths for China's CLC projects. An evaluation index system is established from three perspectives of cultivated land quality, consolidation potential and investment implementation condition based on the analysis of the executors and influencing factors of CLC investment implementation. Then, China's CLC investment implementation models are divided into three types, named new-type agricultural operation organization leading model, government leading model and farmer leading model, and a systematic analysis of implementation paths for varied models is conducted. Results show that it can instruct regional CLC investment implementation and enhance implementation efficiency of cultivated land investment.
•We proposed the investment implementation models and paths for China’s CLC projects.•Evaluation index system of investment implementation models was established from three perspectives.•The methods were demonstrated in Suixi County and can be applied to many other cities.
Abstract It has been shown that land fragmentation can negatively impact the efficiency of farming. Therefore, experts recommend land consolidation process, as a logical and workable solution to ...solve the problems and complications caused by land fragmentation. Land levelling and consolidation is a process of land reform that changes the construction of agricultural lands which leads to rural development through reforming farm management. However, a single plan cannot be applied to different regions, even though they might be in the same country. Hence, it is vital to investigate multiple factors in a certain region to devise the perfect consolidation plan. The present study, which is a survey-exploratory research, is conducted to provide a comprehensive model to implement the plan for levelling and consolidation of agricultural lands in the Abu Fazel region of Ahvaz, Iran. This research is an applied field research which uses both library and field methods to collect the required data. The study population is in Abu Fazel in the northeast of Ahvaz in Zargan region. The results of the study show that cultural, social, economic, policy-making, educational, agricultural and managerial factors have an effect on the participation of farmers in the levelling and consolidation of agricultural lands in the study area (p≥0.01). Also, there is a strong positive relationship between these factors and the farmers' participation in levelling and consolidation of agricultural lands (p≥0.01). Among these factors, it is observed that policy is main factor. Policymakers can play an effective role in land consolidation and macro development on the one hand and agricultural and rural development. On the other, by accurately assessing the interactive effect of land consolidation and related factors, along with the effects of this process on the evolution of agronomic systems.
Resumo Tem sido demonstrado que a fragmentação da terra pode impactar negativamente a eficiência da agricultura. Portanto, os especialistas recomendam o processo de consolidação de terras como uma solução lógica e viável para resolver os problemas e as complicações causadas pela fragmentação de terras. O nivelamento e a consolidação da terra são processos de reforma agrária que alteram a construção de terras agrícolas, o que leva ao desenvolvimento rural por meio da reforma da gestão agrícola. No entanto, um único plano não pode ser aplicado a diferentes regiões, mesmo que estejam no mesmo país. Portanto, é vital investigar vários fatores em determinada região para elaborar o plano de consolidação perfeito. O presente estudo, que é uma pesquisa exploratória de levantamento, é realizado para fornecer um modelo abrangente para implementar o plano de nivelamento e consolidação de terras agrícolas na região de Abu Fazel, de Ahvaz, no Irã. Trata-se de uma pesquisa de campo aplicada que usa métodos de biblioteca e de campo para coletar os dados necessários. A população do estudo está em Abu Fazel, no nordeste de Ahvaz, na região de Zargan. Os resultados do estudo mostram que fatores culturais, sociais, econômicos, políticos, educacionais, agrícolas e gerenciais influenciam a participação dos agricultores no nivelamento e na consolidação das terras agrícolas na área de estudo (p ≥ 0,01). Além disso, há forte relação positiva entre esses fatores e a participação dos agricultores no nivelamento e na consolidação das terras agrícolas (p ≥ 0,01). Entre esses fatores, observa-se que a política é o principal deles. Os formuladores de políticas, por um lado, podem desempenhar um papel efetivo na consolidação da terra e no macrodesenvolvimento e desenvolvimento agrícola e rural e, por outro, avaliar com precisão o efeito interativo da consolidação de terras e fatores relacionados, juntamente com os efeitos desse processo na evolução dos sistemas agronômicos.
•Chinese land consolidation spatial management primarily depends on land consolidation zoning.•Current SRRALR-based spatial management experiences many problems.•We offer a new land consolidation ...spatial management system guided by SCGLCF.•The new system covers the four key spatial elements in land consolidation.•It is made up by four zonings suitable for current land management administration.
Land consolidation spatial management (LCSM) has a significant influence on optimizing national territory arrangement in China. Constrained by the absence of proper administration and evaluation mechanisms, the current LCSM system is entirely based on the principle of “Spatial Recognition of Reserved Arable Land Resources”, which eventually causes the loss of distinct management hierarchy and coordination between land consolidation functions and territorial functions. Aiming at providing an optimal path for LCSM in China, this paper proposes a new principle of “Spatial Coordination Guided by Land Consolidation Function” and establishes a new system consisting of national, provincial, municipal and county-level land consolidation zonings, which comprehensively cover the four key spatial elements of land consolidation (territorial function, land consolidation function, land consolidation potential and land consolidation engineering) by using a factor-combination method. Advantages of this new system are described as follows: (1) it recognizes a top-bottom dependent relationship and control mechanism inside LCSM; (2) it coordinates land consolidation functions with territorial functions to effectively promote regional development; (3) it actualizes multiple land consolidation functions with the support of various land consolidation potentials and engineering means; and (4) it provides specific and explicit guidance on single land consolidation project arrangement and coordinates the spatial arrangements of different regional land consolidation activities. To promote the realization of this new system, some important suggestions are also provided, such as establishing diversified and differentiated land consolidation evaluation systems; granting regions autonomy and flexibility over land consolidation project approval, investment and implement standards; and performing land consolidation with the entire region as a complete consolidation object.
Land is a resource with limited availability, but has an ever-increasing demand. Land Consolidation is a realignment activity which can be an alternative in planning a regional development. Land ...Consolidation in Gadingsari Village is a Bantul Regency government program implemented in 2017 located in Nanggulan, Patihan and Wonoroto Villages involving 200 land parcels , with 172 participants for land consolidation and 111,467 m2 of land. Land Consolidation produces land that has good accessibility and regularity of land parcels so it may triggers an increase in land value. An increase in land value can be estimated by modeling the land value before and after land consolidation. One method that is often used in the modeling of land values is the multiple variable linear regression method. The method used in this study involves the price of land as the dependent variable and the independent variable, namely: (1) Road Class; (2) Distance of land parcels to the Economic Center; (3) Distance of land parcels to the Village Government; (4) Distance between land parcels to the tourist site; (5) Distance of land parcels to Health Facilities; (6) Area; (7) Distance of parcels to Main roads; (8) Distance between land parcels of land to the beach; and (9) Land Use. The model formed is then used to calculate the estimated value of land prices before and after the implementation of land consolidation. The estimated value of land produced by the land value model prior to land consolidation ranges from Rp. 11,000 to Rp. 370,000. While the estimated land value for the land value model after land consolidation ranges from Rp. 21,000 to Rp. 605,000.
