A multi-criteria model for land valuation in the land consolidation

Land consolidation is an effective technique in land management that contributes to sustainable rural development. Land valuation is one of the most important steps in land consolidation because it plays an important role in the reallocation process. Land valuation is also an important problem in Turkey as in many countries in the world. Because the lands will be reallocated at the end of the consolidation process, it is very important to determine the precise value of each parcel. However, the methods used in land valuation in many countries lag behind current techniques and technologies. For this reason, a new method for land valuation is needed. The purpose of this study was to develop a new model based on multi-criteria calculations that is suitable for today's technologies and addresses the weakness in the current land valuation methods. In a case study of Solak, Antalya, Turkey, we identified fourteen key land value factors. Those factors were assigned weights by the Land Valuation Committee, academic staff, engineers, and local landowners. The weights were then integrated into a framework called the Land Quality Index. The land quality index factors are the criteria for evaluating the geographical, physical, and socio-economic structure of the region. The scores for each factor on each parcel were determined using GIS software. The total score of fourteen factors was then converted to a 100-point scale, that comprised the Land Quality Index. The land value of each parcel was determined by adding the soil index to the Land Quality Index. In our study, we also created three different models to investigate how the parameters were apportioned during the land valuation. We found that, while the current method used by the government agency (General Directorate of State Hydraulic Works) classified the lands into five groups, our methods classified the lands into 17, 20, 24 groups, respectively. In addition, while the deduction rate was 4.97 % in the current method, they were 4.89 %, 4.86 % and 4.85 % in our new models, respectively. The method we proposed in this study determined land values more accurately, precisely, and fairly compared to current method used by General Directorate of State Hydraulic Works. It is suggested that our models could be used instead of the current method in the land consolidation works in Turkey.     

Forest land consolidation and its effect on climate

Land use changes and forests both play an important role in combating climate change. The climate effects of forest land consolidation have, however, not been studied in detail. As such, this study identifies a number of possible climate effects of forest land consolidation. To specify these, the increased carbon storage in the Pahkakoski land consolidation project (Finland) due to increased forest growth is valued through substitution costs. The results show that the value of the increased carbon storage in the project area is approximately 750 000 euros, or €153/ha. This emanates from the increased growth due to remedial drainage and from the increased forested area. The result is, however, sensitive to changes in the shadow price of carbon. Likewise, the study recognises a need for studies concerning the total climate effect of measures, such as remedial drainage that may also release carbon from the ground. While the overall effects of forest land consolidation are difficult to estimate with current knowledge, this article highlights the potential of land consolidation to combat climate change.

Towards sustainable rural development in Central and Eastern Europe: Applying land consolidation

Over the past twenty years, social and economic decline in rural areas has intensified in the Central and Eastern European countries. A precondition for the reversal of this decline is the implementation of new policies in relation to the fundamentals of land ownership and management. In addition to addressing the problems of land ownership fragmentation, these should include measures to improve agricultural production and employment, taxation policy, and legislation to protect land ownership rights, within the context of acknowledging environmental and sustainability considerations. In Europe, the requirement for readjusting unfavourable land fragmentation and promoting the appropriate use of land combining with positive environmental solutions is expected to create new sustainable land management systems. The consolidation of land ownerships may be an effective and active land management instrument which not only addresses the problems of land fragmentation, but also, if applied sensitively, may be an instrument for delivering sustainable rural development in a wider context. The aim of this research is to investigate land consolidation as an essential tool to create sustainable rural areas in Lithuania.     

Effects of different land reallocation models on the success of land consolidation projects: Social and economic approaches

One of the most important steps in land consolidation (LC) is the land reallocation work, which has a prominent effect on the LC success. For this reason, land reallocation should be handled carefully. There are interview and block priority-based models for land reallocation. The application of different models may have either positive or negative effects on the success of land consolidation.     

The assessment of land valuation in land consolidation schemes: The need for a new land valuation framework

There are principally two ways for quantifying the land value of parcels in land consolidation schemes. The first approach involves assigning an agronomic value based on soil quality and land productivity represented by a score while the second method determines the market value signified in monetary terms. In Cyprus, the market value is employed, which is defined through an empirical process based on visual inspection of all parcels and hence it constitutes a type of mass land appraisal. This process presents weaknesses regarding time, costs, transparency, accuracy, reliability, consistency and fairness. In addition, the lack of adequate sales transactions in rural areas further complicates the whole process. Consequently, these deficiencies have adverse effects in the preparation of land consolidation plans and cause arguments between landowners and the authorities carrying out each scheme. Although experts are aware of this issue, there is a lack of research investigating land valuation factors and the quality of this traditional process. Therefore, this paper discusses, explores and assesses the land valuation undertaken by the Land Valuation Committee (LVC) in a case study area in Cyprus and proposes a new framework for carrying out this process. The assessment of the current process is undertaken by employing advanced spatial analysis techniques, including multiple regression analysis (MRA) and geographically weighted regression (GWR) within a GIS. Results show that eight out of fourteen land valuation factors related to parcel location characteristics, legal factors, physical attributes and economic conditions are the most significant. In addition, although the basic regression fits are quite good, some of the assumptions required for testing the hypothesis are not met, indicating unreliability and inconsistency in the relationships modelled. Furthermore, the presence of spatial autocorrelation reveals important regional variation in these factors suggesting significant inconsistencies in the valuation policy applied by the LVC. The latter two findings confirm experts’ concerns and suggest the need for a new land valuation framework that is designed to overcome the problems of the current process. The application of this framework and the investigation of various critical relevant issues is the core of ongoing further research.     

Use of the Migrating Birds Optimization (MBO) Algorithm in solving land distribution problem

Land distribution is an important process in Land Consolidation (LC) projects where agricultural parcels are reallocated to predetermined blocks. Land distribution is a process that takes a long time, requires high operating costs, and conflicts between landowners occur frequently. The parcels are tried to be placed in the best and most appropriate place of the existing blocks by considering many parameters in the distribution stage. Therefore, the placement of new parcels in blocks is seen as an optimization process. In LC projects, this process is carried out manually by technical staff using a software and thus it becomes a process that takes weeks and even months. Various methods have been developed to solve this important stage of the LC projects. It is required to find the best solution, since this issue is an optimization problem. This study aims to develop a new land distribution method. For this purpose, land distribution were carried out by use Migrating Birds Optimization (MBO) Algorithm. Used land distribution method in practice and the results of the new developed method were compared and thus the usability of the method that developed by us was tested. With this study, it has developed a new and successful distribution method according to the preference of land owners.     

Proposed algorithm for the identification of land for consolidation with regard to spatial variability of soil quality

The quality of soil is one of the most significant factors having a real impact on the potential level of agricultural crops. Therefore, it is a significant element shaping the profitability of agricultural production in the specific area. Familiarity with spatial variability of soil quality classes in respective voivodeships has an impact on planning the development of agricultural areas and effective allocation of money to rural spatial restructuring. This element also provides important information in the process of consolidation works programming which takes place at the regional government level. This data is characterised by very long usability due to a small number of changes referring to classification of land entered into the land and building survey. Data on the quality and suitability of soil in the analysed area was acquired from the analysis of data from the land and building survey. Analyses were carried out in 3 poviats of Lublin voivodeship located in the eastern part of Poland covering an area of 501 132.9 ha, split into 610,160 plots. This paper presents an algorithm designed by the author for identifying areas in which land consolidation works should be performed, including its practical application using the adopted sample. The algorithm identifies areas characterised by the highest soil quality, which makes it possible to indicate areas where land consolidation work should first be undertaken.     

Fragmentation of land ownership in Slovakia: Evolution,context, analysis and possible solutions

Land ownership fragmentation is currently a very topical issue in Slovakia. In particular, small farmers complain that even 30 years after the end of the previous (“real socialist”) regime, there has been no significant change in the structure of agricultural land use. The subject of the article is not the land fragmentation in terms of use. In Slovakia, the problem is rather the opposite. This contribution deals with fragmentation of ownership that is mostly invisible in the landscape. Usage still dominates over the ownership and the real landowner cannot get his or her own property in a simple way. The reason for this is huge fragmentation of land ownership, which makes it virtually impossible to actually claim it. Well known solution is the land consolidation that does not advance at a rate that would guarantee the rights (and obligations) of all owners in the foreseeable future in Slovakia. Neglecting the land fragmentation by authorities leads to tense situations between landowners and land tenants and also co-causes a stagnation of rural development and issues with landscape protection. The paper describes the specific state of land ownership in Slovakia and attempts to explain this complicated situation on a sample of 50 historical and modern ownership documents. This contribution has the ambition to specify the largely yet unresolved problems that arise from the current state of massive fragmentation of land ownership. The aim of the paper is also to fill in the information gap on the topic, not only in the national context.     

On the structural development of arable land in Finland – How costly will it be for the climate?

Finland is the most sparsely populated country in the European Union. Finland's northern location presents special challenges for the profitability of agriculture. At the same time Finland has a fragmented property structure which means that each farmer cultivates a number of separate fields that are scattered into small parcels located around the village. The situation came into being because of land reforms whose purpose was to handle socio-political issues and not to improve the feasibility of farms. It is obvious that this inefficient property structure increases the cultivation costs but what is often forgotten is that it also increases the harmful emissions to the climate.The purpose of this article is to present the property structure of arable land and its development in Finland until 2020. The main objective is to estimate the monetary value for those climate impacts that the development causes. The study was set up to analyze land management tools and their capabilities to handle the future challenges. First, the study estimates how much petrol consumption increases because of the increased need for agricultural traffic due to the forecasted development of property structure. Secondly, the study estimates a monetary value for the increased emissions to the climate due to the changes in petrol consumption. To estimate the monetary value of the climate effect a substitute cost method is used.It was estimated that by year 2020 the agricultural working hours will increase by almost three million hours per year from its current level because of the expected changes in property structure. By using the information about petrol consumption and emission rate of petrol, it was calculated that the total increase in CO₂-emissions will be more than 200 000 tkgCO₂ per year. By using the information about the level of increase in CO₂-emission and their shadow prices, it was calculated that the changes in property structure will cost 37 million euros until year 2020 and 544 million euros until year 2050. The sensitivity analysis showed that the results are strongly dependable on shadow prices of CO₂-emissions, property structure's development scenarios and the expected fuel efficiency of agricultural machinery. On the other hand it also showed that the impact will be remarkable especially in the long run if the changes in property structure cannot be prevented.The study showed that there is a massive potential for land management activities. But since the current land management tools that are utilized in Finland are not efficient to handle the future problems the toolbox should be renewed. As the renewing work requires both legislative and organizational changes the progress will take time. This means that the harmful impacts that the development of property structure causes will be realized in the upcoming decades. The study concludes that the increase in CO₂-emissions doesn’t concern only Finland but also other EU countries and that is why the matter should be investigated in other countries as well.     

The factors influencing the profitability of leased land on dairy farms in Ireland

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.     

Evaluation of the environmental effects of intensive land consolidation: A field-based case study of the Chinese Loess Plateau

The large-scale implementation of the Grain for Green project on the Chinese Loess Plateau since 1999 has greatly increased the vegetation coverage and rapidly decreased the agricultural land by converting slope cropland to planted vegetation (forest and grasslands). However, the geological, hydrological, ecological, and agricultural effects of the Gully Land Consolidation (GLC) project launched at Yan’an City in 2011 to address these land-use problems are not clearly understood. To assess the project outcomes in this region, we examined 71 of the 193 subprojects (61 treated gullies and 10 untreated gullies); measured geological, hydrological, ecological, and agricultural indices in the field; and tested disturbed (n = 447) and undisturbed (n = 142) soil samples (e.g., particle size distribution, saturated hydraulic conductivity, bulk density, and heavy metal contents). We found that: (1) slope stability improved for 67 % of the subprojects, (2) severe swamping was found only for 2 % of the subprojects, (3) the average increase in NDVI was 0.0231, 69 % of treated gullies NDVI was increased, and (4) crop yield was overall improved. There were no significant differences between the treated and untreated gullies in soil texture, saturated hydraulic conductivity, bulk density, or heavy metal contents (Cr, Zn, Cu, Ni, Pb), although particle size contents (range of 0.05 mm – 0.20 mm) differed significantly (p < 0.05). To promote successful gully land consolidation, the GLC project should (1) prioritize slope stability and long-term maintenance of water preservation facilities in gullies, (2) use bioengineering to accelerate the maturation of newly created land, or develop new cropping system after the GLC project; (3) on the basis of Grain for Green, integrate the GLC project, and modern agriculture to be complementary.     

Tenure,land rights,and farmer investment incentives in China

The goal of this paper is to understand the nature of the property rights associated with China's land tenure systems and to study the impact of these property rights on agricultural production efficiency. The results show that land tenure and associated property rights in rural China affect the production behavior of farmers. The most robust finding is that the right to use land for long periods of time encourages the use of land-saving investments. While the results show that land tenure affects agricultural production decisions, the difference between collective and private plots, however, is small compared to the private plot - communal productivity gap that existed in the pre-reform period.     

Violent visions of an ownership society: The land administration project in Petén, Guatemala

This article is a case study of phase one of the World Bank's land administration project in Petén, Guatemala. Although the project's stated aims are merely to formalize an existing set of individual landed property rights, this development intervention necessarily changes the property regime, thereby changing underlying relationships that land as property embodies. Impact evaluations conducted by development economists may fail to substantively address displacement and violence that occur as a short-term effect of the project and long-term disparate impacts of the project that may exacerbate existing inequalities. The case of Petén also highlights the possibility for violent enforcement of property boundaries, where conflict surges between the disenfranchised and those who gain power under the new property regime.     

Formalisation of land rights in the South: An overview

Formalisation of property rights has recently been proposed as a way of reducing poverty. The poor, it is said, do not lack assets, they lack only the formal, protected rights necessary to make these assets engines of entrepreneurship, thriving markets, and information networks. Historical evidence with regard to formalisation programmes is, however, mixed at best, and current universalist proposals contain numerous flaws. A more context-specific and flexible approach is needed, with greater attention to local settings and specific objectives and tools. Property formalisation should not be considered merely a technical tool but must take account of politics and culture.     

Impacts and causes of land fragmentation, and lessons learned from land consolidation in South Asia

Landholdings and land parcels in South Asia are undergoing fragmentation, thereby accelerating the pace of their degradation and constraining agricultural development. Based on experiences gained in the region and elsewhere, this paper finds the fragmentation of small landholdings and tiny land parcels detrimental to land conservation and economic gain, thereby discouraging farmers from adoption of agricultural innovations. Primarily induced by the dependency of the major proportion of ever growing population on agriculture, the process of land fragmentation has been reinforced by the law of inheritance of paternal property, lack of progressive tax on inherited land, heterogeneous land quality and an underdeveloped land market. South Asian countries have had adopted policies and legal measures for facilitating land consolidation. However, desirable results were not achieved, as such interventions could not address structural causes of the problem. Broad policy and legal measures have been outlined for facilitating land consolidation in a sustainable way.     

Trends in land ownership fragmentation during the last 230 years in Czechia,and a projection of future developments

A high level of fragmentation of farmland ownership is an important underlying cause of land degradation and, at the same time, an obstacle to sustainable land management. This study makes the first-ever analysis of long-term trends in the rate of fragmentation. Our study covers the period from the earliest stages of the current form of ownership patterns at the end of the 18th century until the present day. On the basis of significant predictors that have been identified (initial fragmentation, population growth, historical development of inheritance laws and of the land market, natural soil fertility and landscape type), we go on to project probable developments for the period from 2016 to 2045. A total of 102,984 land parcels in 56 cadastral units in the territory of Czechia have been analysed on the basis of data from four years (1785, 1840, 1950, 2015). Our study considers the development of two basic indicators of fragmentation – Mean Parcel Size and Number of Owners per 100 ha. The Mean Parcel Size has decreased over a period of 230 years from 1.08 ha to 0.64 ha, at a mean rate of −0.26% year⁻¹. During the same period, the Number of Owners per 100 ha has risen from 17.50 to 79.66, at a mean rate of 0.61% year⁻¹. A detailed analysis of the development trends confirms significant spatial variability and also time variability of the rates of the two indicators. The analysis also shows their mutual complementarity: growth in the rate of one of the indicators is usually accompanied by a drop in the other. The general trend that we project for the territory of Czechia in the upcoming 30 years is that there will be further diminution of the physical size of land parcels (continuing fragmentation of land parcels) accompanied by a reduction in the Number of Owners (defragmentation of land ownership).     

Extra-legal land market dynamics on a Guatemalan agricultural frontier: Implications for neoliberal land policies

Neoliberal land policies such as land administration seek to improve property rights and the efficiency of land markets to boost rural economic production. Quantitative studies of pre-existing land markets can help planners to tailor these policies to local conditions. In this article we examine an extra-legal land market currently being modernized by a World Bank-sponsored land administration effort. Specifically, we use a hedonic-type revealed preference model and household survey data to estimate the factors affecting extra-legal land prices along an agricultural frontier in Petén, Guatemala. Our model indicates that land value is significantly affected by land attributes including location, tenure status, presence of water, distance to roads, and distance to landowners’ homes, and that land prices in the northwestern Petén are estimated to have risen on average 26.5% per year between 1977 and 2000. We contend that this rate of increase provides a strong incentive for colonists to speculate in land rather than invest in state sanctioned property rights. We conclude that if frontier development programs, such as land administration, are to become attractive to settlers in Petén and elsewhere, they must compete favorably with economic incentives associated with land speculation, or alternatively, target landowners who are not interested in playing the land market.     

Trends in private land conservation: Increasing complexity,shifting conservation purposes and allowable private land uses

The terrain of private-land conservation dealmaking is shifting. As the area of private land protected for conservation increases, it is time to understand trends in private-land conservation agreements. We examined 269 conservation easements and conducted 73 interviews with land conservation organizations to investigate changes in private-land conservation in the United States. We hypothesized that since 2000, conservation easements have become more complex but less restrictive. Our analysis reveals shifts in what it means for private land to be “conserved.” We found that conservation easements have indeed become more complex, with more purposes and terms after 2000 compared to conservation easements recorded before 2000. However, changes in restrictiveness of conservation easements varied by land use. Mining and waste dumping were less likely to be allowed after 2000, but new residences and structures were twice as likely to be allowed. We found a shift toward allowing some bounded timber harvest and grazing and a decline in terms that entirely allow or prohibit these working land uses. Interviews revealed staff perceptions of reasons for these changes. Our analysis suggests that “used” landscapes are increasingly important for conservation but that conserving these properties stretches the limits of simple, perpetual policy tools and requires increasingly complex and contingent agreements.
