Extreme farmland ownership fragmentation is becoming a limiting factor for sustainable land management in some countries. Scattered, excessively small parcels cease to be viable for individual farming, and owners feel forced to rent these parcels to larger enterprises farming on adjacent land. Our study demonstrates a phenomenon that we call the Farmland Rental Paradox, where very small parcels tend to create large production blocks by being rented to larger farmers, and therefore to significantly homogenize the land-use pattern. The parcel size established as the threshold for this phenomenon is 1.07 ha. Below this threshold, the smaller the parcels were, the larger the blocks that they tended to create.Using the example of the Czech Republic, a state with extremely high farmland ownership fragmentation, it is demonstrated that this phenomenon can currently determine the land use of up to 40% of the country's farmland. Our study also points to other countries where this phenomenon may apply, especially the transitional countries of Central and Eastern Europe.The study discusses the tempo of the fragmentation process, which accelerates exponentially in countries with the equal inheritance system. It goes on to discuss defragmentation, social impacts of the dominance of the land rental market, and environmental impacts of significant homogenization of the land-use pattern. The serious negative impacts of extreme land-ownership fragmentation show that this phenomenon can be considered as a significant form of land degradation. 相似文献

In recent negotiations related to agriculture in connection with EU accession, the candidate countries asked for and received a period of 7–12 years exemption from EU rules with respect to the free movement of capital for the purpose of purchasing agricultural land. This means that, with some exceptions, foreigners will be prevented from buying land in most new member countries for a transitional period. The negotiating governments of the prospective new Member States claimed that a transitional period would be necessary because land prices are much lower in their countries than in the 15 EU ‘old’ countries. They claimed that without such an exemption, land in their countries would be bought cheaply by people of the ‘old’ EU countries, thus causing land scarcity for domestic farmers. However, statistical data do not support fears about land scarcity at present or in the future. The reasons for ‘keeping away’ foreigners from ‘national land’ are ideological rather than economic. Land continues to play a crucial role in rural-nationalist ideology, which has survived even after the disappearance of its bases, i.e. rural over-population and genuine land scarcity. 相似文献

The Central American Dry Corridor (CADC) is a trans-border region characterized by climatic and ecological continuities. It is expected to experience rising aridity and severe hydro-climatic events due to climate change. Subsistence agriculture and other rural livelihoods to which land cover is central are widely practiced in this impoverished territory of approximately eleven million people.The CADC’s land cover was profiled to determine: a) how it differs from Non-CADC areas, and b) the role of land use in shaping these differences. Spatial autocorrelation analysis using satellite data showed that forest cover is a third less prevalent in the CADC than in the Non-CADC while the share of mosaic vegetation and mosaic cropland is nearly double. A naturally prevalent cover type in the CADC, tropical dry forest (TDF), has been largely eliminated.The significantly lesser proportion of forest and greater percentage of coverage consistent with agriculture and ranching implicate land use conversion, specifically deforestation for agricultural expansion and cattle ranching, in shaping CADC land coverage. The process began in the mid-1800s when small-scale agriculturalists migrated to the region followed by large-scale export crop and beef production, primarily for international markets. Deforestation peaked after WWII, concluding by the 1990s with the conversion of most woodlands. Similar patterns now threaten forests along the Caribbean coast.Traditional land use practices cannot sustain local communities or preserve the resource base, thereby contributing to rural outmigration. Adopting sustainable practices and promoting livelihoods strategies leading to forest regeneration will be fundamental for CC adaptation in the CADC. 相似文献

The novelty of this study lies in the analyses of legislation concerning land use policies by examining the specific boundary between land ownership and land take. The basic motive was that the European Commission (EC) withdrew the Soil Framework Directive (SFD) in 2014 following the objections of certain Member States (MS) who countered that as most lands are privately owned, they should not fall under the remit of public governance. Since the withdrawal of the SFD land take is an issue receiving more attention. The legal content of ownership rights has been subjected to constant debate in the context of land-use policies and planning practices, which raises the questions of who decides how the land can be used and whether administrative authorities give priority to non-agricultural uses. Our study seeks to explore these issues through the lens of property law by comparing different legislations on access to land on three levels of policy implementation: the EU, the national, and the local levels. MS legislations are highlighted through the example of Hungary in two aspects: (1) regulation regarding Access to Land and Land Ownership Rights (ALOR), and (2) legislation and results of the LANDSUPPORT decision support system concerning Land Take Changes (LTC). We designed figures to demonstrate how policymakers can use the new LANDSUPPORT platform to show the gaps and inconsistencies among the above aspects. We found that the legislative regulations concerning private land use to achieve soil protection objectives remain the weakest link in the environmental protection legislation of the EU. Anxieties concerning built-in legal guarantees on each of the studied levels actualise our research. Currently, global land management is not on the political table although common European legislation might be able to preserve land for agricultural use. 相似文献

Land fragmentation has restrained the development of Chinese agriculture with the application of agricultural machinery. Meanwhile, agricultural pollution has caused serious problems with development. To address these problems, China's government proposed a new farmland lease policy and built larger farms beginning in 2013. However, changes in land fragmentation may also have unexpected problems for Chinese agriculture. This study investigated the effects of these changes on changes in land use, the application of machinery and agricultural pollution. We analyzed a developed area (in the fields of both agriculture and industry) and studied the decision-making habits of farmers in the area. An agent-based model was proposed with the same decision-making habits as in the real world. The results indicated that land lease increased agricultural profits very little in Jiangsu, China. Meanwhile, the application of land lease policy increased pollution. To alleviate pollution and increase profits, a new policy for large automatic protection machinery (i.e., large spraying machinery) should be introduced by governments simultaneous with land lease policy. Farmers could realize greater profits through the introduction of land lease policy and high-efficiency machinery. The sustainable development of agriculture in Jiangsu requires the integration of these government policies. 相似文献

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). 相似文献

China's urbanization has resulted in significant changes in both agricultural land and agricultural land use. However, there is limited understanding about the relationship between the two primary changes occurring to China's agricultural land – the urban expansion on agricultural land and agricultural land use intensity. The goal of this paper is to understand this relationship in China using panel econometric methods. Our results show that urban expansion is associated with a decline in agricultural land use intensity. The area of cultivated land per capita, a measurement about land scarcity, is negatively correlated with agricultural land use intensity. We also find that GDP in the industrial sector negatively affects agricultural land use intensity. GDP per capita and agricultural investments both positively contribute to the intensification of agricultural land use. Our results, together with the links between urbanization, agricultural land, and agricultural production imply that agricultural land expansion is highly likely with continued urban expansion and that pressures on the country's natural land resources will remain high in the future. 相似文献

Bucharest is a city in transition from its communist past to a market economy, but poor urban planning in is impacting adversely on contested spaces. Lack of effective and strictly enforced regulation and public sector indecision, mixed with problems inherited from the Ceausescu regime, generate many examples of poor urban planning and management. One such example concerns the uncertain future of Văcăreşti “Lake”, our in-depth case study, which is an encapsulated 184 ha wetland whose management has been particularly poor. Employing a mixed methodology of mapping the evolution of the area in question and conducting interviews with surrounding residents and experts in the urban planning or public administration, we demonstrate how lack of an effective planning system and appropriate policies serves to exacerbate conflict between interested parties. Initially there was a conflict between former land owners and authorities, after which developers, surrounding populations, urban planners and ecologists were added. Worse still, the juridical owners of the site are unresolved! Many government agencies and the Bucharest municipality have also compounded the problem by failing to take a lead in future planning and conflict resolution by adopting a passive management approach, which is a recipe for inaction in a poorly regulated land market. Thus, incoherent land use policy has greatly amplified individual and professional conflict both at the local level and city-wide. 相似文献

Changes in land use and land tenure can influence both physical fragmentation and ownership fragmentation of landscapes, with implications for biodiversity. In this study, we evaluated changes in land use and land tenure in the Tijuana River Watershed, a region of high biodiversity and endemism, following the implementation of a new Agrarian Law which allowed for privatization and sales of communal land (ejidos) beginning in 1992. In order to understand changes in land use and cover, we constructed maps from aerial photographs and Aster images and measured changes between 1994 and 2005. In order to understand changes in land tenure, we collected data from Mexican government sources on ejido land size, ownership, and sales, and we conducted 55 structured interviews with ejidatarios in the watershed. Our results demonstrate that land-use/cover change between 1994 and 2005 was dominated by an increase in urban area and grasslands, and a decrease in coastal sage scrub, chaparral, and, to a lesser degree, agriculture. In particular, the conversion of coastal sage scrub has left a far more fragmented landscape than existed in 1994. In addition, most of the ejidos in the watershed, as well as individuals interviewed, had participated in some stage of the land certification and titling process allowed by the new Agrarian Law, resulting in substantial changes in land tenure. However, land tenure security appeared to play a larger role than a desire to sell land and, contrary to studies from other regions, full title to the land was obtained in a range of urban and rural settings, rather than primarily on land closest to urban zones. Our results suggest that past predictions regarding future urban growth and fragmentation of native vegetation in the region have proven accurate and highlights regions of change that merit further study. 相似文献

Impact Assessment was introduced by the European Commission in 2002 in order to make policy development more transparent and improve the ‘quality’ of European policies. Cross-sectoral consultation, broad participation and the quantitative assessment of the impacts of policies are significant elements of this process. This article specifically addresses the role of tools modelling the impact of policies on land use in Impact Assessment. The choice of a specific modelling tool is conceptualised as an action situation interlinked with other action arenas. The article aims to uncover the institutions structuring the action situation. The outcome of the empirical work suggests that two types of Impact Assessments can be distinguished. Impact Assessments either substantively contribute to the specific policy that the Commission proposes or they legitimise policy choices ex post that have already been adopted. The legislative procedure that applies to a specific policy sector, the policy making culture in the DG and the stakes that are at issue seem to influence whether Impact Assessments contribute to policy development, or legitimise it. Furthermore, the article describes the situation in which desk officers choose a modelling tool throughout Impact Assessment. To advance their careers desk officers aim to produce policy proposals which respond to the issues raised by the actors involved in Impact Assessment and specifically in policy development and, later on, adoption. Therefore, desk officers’ preferences are shaped by the community that is involved in policy development and Impact Assessment. The article describes what role modelling tools play in European Impact Assessment procedures and it names the heuristic of criteria which desk officers use to choose a modelling tool. Besides several technical and data problems of modelling land use impact, it seems to be unlikely that land use will become a significant dimension of Impact Assessment and modelling as it is confronted with an unfavourable institutional environment at the European level. 相似文献

Landslide risk reduction in developing countries is preferable to disaster remediation and recovery, in both social and economic terms. The implementation of landslide preventative measures is closely related to the development of ‘good practice’ in land use management, at government and community levels, especially in the face of rapid and unplanned urbanisation. These areas of poverty and vulnerability to ‘natural’ hazards present a challenging environment for which to develop realistic land use policies and practices. There is little evidence of on-the-ground delivery of landslide risk reduction. However, scientifically based landslide risk reduction strategies can be effective. In the Eastern Caribbean construction of drainage networks in communities afforded an improvement in slope stability – after a 1 in 100-year rainfall event there were no landslides on previously unstable slopes in densely populated urban communities. This has been recognised in policy terms in the first ever Caribbean-wide, 5-year risk reduction programme. Such evidence represents an important first step in developing realistic land use policies for landslide-prone areas occupied by those migrating to urban centres in the Eastern Caribbean. 相似文献

The effect of decoupling on marginal agricultural systems: Implications for farm incomes,land use and upland ecology 总被引:1,自引:0,他引:1

In many parts of Europe, decades of production subsidies led to the steady intensification of agriculture in marginal areas. The recent decoupling of subsidies from production decisions means that the future of farming in these areas is uncertain. For example, in the uplands of the United Kingdom, an area important both for biodiversity conservation and ecosystem service provision, hill farmers steadily increased stocking densities in response to headage payments but must now reconfigure farm businesses to account for the shift to the Single Farm Payment scheme. We examined hill farming in the Peak District National Park as a case study into the future of marginal agriculture after decoupling. We surveyed 44 farm businesses and from this identified six representative farm types based on enterprise mix and land holdings. We developed linear programming models of production decisions for each farm type to examine the impacts of policy changes, comparing the effects of decoupling with and without agri-environment and hill farm support, and evaluating the effects of removal of the Single Farm Payment. The main effects of decoupling are to reduce stocking rates, and to change the mix of livestock activities. Agri-environmental schemes mediate the income losses from decoupling, and farmers are predicted to maximise take up of new Environmental Stewardship programmes, which have both positive and negative feedback effects on livestock numbers. Finally, removal of the Single Farm Payment leads to negative net farm incomes, and some land abandonment. These changes have important implications for ongoing debates about how ecological service flows can be maintained from upland areas, and how marginal upland farming communities can be sustained. 相似文献

The environmental, cultural and economic consequences of land use change, including abandonment of agricultural use, have been recognized for a long time. It has often been assumed that the transformations of the agricultural systems in developed countries (and particularly in Europe) took place, for the main part, in the immediate years after the Second World War. In this paper we present a review of different statistical and cartographic sources available for a peripheral region in Europe (Galicia, Spain) characterized by small-scale farming and a very fragmented property system, that suggests otherwise: modernization of agriculture apparently took place without major changes in agricultural area until the country gained access to the European Economic Community, and the effect of Common Agricultural Policy reforms during the decade of 1990 is suggested as a major driver for the net decrease of agricultural area in the region between 1956 and 2004. On the other hand, this paper emphasizes the spatial complexity of agricultural abandonment with a case study, showing a large degree of variability at municipal scale and thus the need of future EU-level projects to work at least at municipal (Local Administrative Units 2, LAU 2) level. Finally, a multinomial logistic model for observed changes is included that shows how biophysical limitations were the main drivers behind abandonment of agriculture at parcel scale, while structural qualities related to property structure were strongly associated to the incorporation of former shrublands to agricultural use. Besides, Farm Structure Surveys were revealed as an unreliable source for the assessment of changes in total agricultural area in the studied region. 相似文献

Changes in rural land use to reduce flood risk are encouraged by governments in many countries, but they may face considerable opposition by land managers. Local participative processes are thought to help overcome opposition. This article presents an evaluation of an intensive participative process set up between land managers and governmental agencies following two severe floods in the transboundary Bowmont–Glen catchment in Scotland and England. A combination of interviews and documentary analysis is used. The research demonstrates that the participative process contributed to greater uptake of rural land use change and improved compliance with existing environmental policies. There were nevertheless low levels of social learning amongst participants. Two institutional designs for improving policy implementation are presented. 相似文献

The protection of agricultural land and forests is a relatively new concept in Poland, and it began with forest protection in the 1920s. The first regulations on the protection of agricultural land were introduced only in the 1960s. Agricultural land and forests received comprehensive protection pursuant to the provisions of the Act of 26 October 1977 on the protection of agricultural land, forests and land recultivation. This legal act set the foundations for the protection of farmland and forests in successive decades.The aim of this study was to determine the influence of farmland and forest protection on spatial planning and to highlight the loss of agricultural and forest land resulting from conversion to other purposes. Legal regulations pertaining to spatial planning and the protection of agricultural and land forests were analysed. The scale of the problem was identified, and future land-use types were forecast based on the data developed by Statistics Poland (GUS). The existing spatial plans (municipal master plan - MMP) were analysed to determine the conversion loss index (CLI) associated with the conversion of agricultural land and forests to other uses. Legal regulations pertaining to the protection of agricultural land and forests were also analysed, and the extent of the relevant conversion measures was determined. The study demonstrated that urban development and the inevitable urbanization of rural areas contribute to the loss of agricultural and forest land that are converted to other uses. 相似文献

In rural Ecuador and elsewhere in Latin America, the departure of migrants and the receipt of migrant remittances have led to declining rural populations and increasing cash incomes. It is commonly assumed that these processes will lead to agricultural abandonment and the regrowth of native vegetation, thus undermining traditional livelihoods and providing a boon for biodiversity conservation. However, an increasing number of household-level studies have found mixed and complex effects of out-migration and remittances on agriculture. We advance this literature by using household survey data and satellite imagery from three study areas in rural Ecuador to investigate the effects of migration and remittances on agricultural land use. Multivariate methods are used to disaggregate the effects of migration and remittances, to account for other influences on land use and to correct for the potential endogeneity of migration and remittances. Contrary to common assumptions but consistent with previous studies, we find that migrant departure has a positive effect on agricultural activities that is offset by migrant remittances. These results suggest that rural out-migration alone is not likely to lead to a forest transition in the study areas. 相似文献

In this paper we present a framework for understanding regional land use processes by incorporating the concept of agglomeration economies into agricultural frontier theory. We show that agricultural firms can obtain positive externalities from locating in close proximity to other agricultural firms, leading to agglomeration economies. Agglomeration economies lead to high levels of competition and diversity within a local agricultural supply chain and influence local prices, information flows, and private enforcement of environmental institutions. We use the theory of agglomeration economies to understand the development of soybean production in two counties along the Santarém-Cuiaba (BR-163) highway in the Brazilian Amazon: Santarém, Pará and Sorriso, Mato Grosso. We conclude that differences in environmental and land tenure institutions influenced the occurrence of agglomeration economies in these two counties, which in turn affected the total factor productivity of soy in each region. In particular, the supply chain became extremely competitive and diverse in Sorriso where few environmental regulations existed, while environmental restrictions reduced the diversification of the supply chain in Santarém. The presence of a soy agglomeration economy in Sorriso spurred innovation, increased productivity, and led to extremely rapid soy expansion in that county, while the monopolistic supply chain in Santarém reduced producers’ access to land and capital and impeded soy expansion. 相似文献

Food insecurity remains persistent in the Global South due to constraints in food production capacities and intricate land tenure systems that stifle investment in agriculture. In the urbanized regions, uncontrolled urbanization and non-compliant land use systems have further worsened the potentials for urban food production. This research is based on a case study of the Wa Municipality in order to assess the influences of customary land allocation and peri-urbanization on land use planning and foods systems in Ghana using explorative and narrative research approaches. The study identified that customary stakeholders responsible for allocating such lands in the Wa Municipality were indiscriminately converting large tracts of hitherto agricultural lands to urban land uses. Statutorily prepared land use plans are hardly enforced and the planning priorities are on residential and commercial land uses that command higher land values to the detriment of agricultural lands. Weak institutional linkages also characterize the mandated planning and land administration institutions, with a planning system that is reactive rather than proactive in addressing development control challenges across the country. There is the need for planning authorities to adopt participatory land uses planning together with customary landholders and educating them on the essence of comprehensive land use planning approaches. Based on the findings, local governments need to partner landowners to identify and reserve high potential agricultural land for sustainable urban food production. 相似文献

Impact of land fragmentation and resource ownership on productivity and efficiency: The case of rice producers in Bangladesh 总被引:5,自引:0,他引:5
The paper analyzes the impact of land fragmentation and ownership of resources on productivity and technical efficiency in rice production in Bangladesh using farm level survey data. Results reveal that land fragmentation has a significant detrimental effect on productivity and efficiency as expected. The elasticity estimates of land fragmentation reveal that a 1% increase in land fragmentation reduces rice output by 0.05% and efficiency by 0.03%. On the other hand, ownership of key resources (land, family labour, and draft animals) significantly increases efficiency. The mean elasticity estimates reveal that a 1% increase in family labour and owned draft animal improve technical efficiency by 0.04% and 0.03%, respectively. Also, a 1% increase in the adoption of modern technology improves efficiency by 0.04%. The mean technical efficiency in rice production is estimated at 0.91 indicating little scope to improve rice production per se using existing varieties. Policy implications include addressing structural causes of land fragmentation (e.g., law of inheritance and political economy of agrarian structure), building of physical capital (e.g., land and livestock resources), improvements in extension services and adoption of modern rice technology. 相似文献
