Towards sustainable rural development in Central and Eastern Europe: Applying land consolidation 总被引:11,自引:0,他引:11
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. 相似文献

Public preferences for landscape features: The case of agricultural landscape in mountainous Mediterranean areas 总被引:3,自引:0,他引:3
Provision of landscape amenities produced by farmers, in addition to their economic function of producing food and fibre, has contributed to a reassessment of the role of agriculture in society. In this paper, we examine whether agricultural landscape provision really responds to a social demand as is argued by those in favour of multifunctionality. Thus, the aim of the present work is two-fold. First, we evaluate rural landscape preferences of citizens from a range of choices in the mountain area of the Alpujarras (south-eastern Spain), and second, we estimate their willingness to pay (WTP) to enjoy each of the landscape characteristics existing in the area. For the empirical analysis, based on a survey of public preferences due to the good public characteristics of landscape amenities, we applied two stated preference methods: Conjoint Analysis (CA) and Contingent Valuation (CV). Three landscape attributes were considered for this analysis: type of vegetation layer, density of rural buildings, and level of slope. Several levels were also considered for each attribute: abandoned fields, dryland farming, irrigated farming, and natural lands were included for the vegetation layer; three levels (low, intermediate and intense) were considered for the level of slope and three levels (none, little and intense) for rural buildings. 相似文献

Reducing carbon emissions from deforestation and forest degradation now constitutes an important strategy for mitigating climate change, particularly in developing countries with large forests. Given growing concerns about global climate change, it is all the more important to identify cases in which economic growth has not sparked excessive forest clearance. We address the recent reduction of deforestation rates in the Brazilian Amazon by conducting a statistical analysis to ascertain if different levels of environmental enforcement between two groups of municipalities had any impact on this reduction. Our analysis shows that these targeted, heightened enforcement efforts avoided as much as 10,653 km2 of deforestation, which translates into 1.44 × 10−1 Pg C in avoided emissions for the 3 y period. Moreover, most of the carbon loss and land conversion would have occurred at the expense of closed moist forests. Although such results are encouraging, we caution that significant challenges remain for Brazil's continued success in this regard, given recent changes in the forestry code, ongoing massive investments in hydro power generation, reductions of established protected areas, and growing demand for agricultural products. 相似文献

This paper analyses the potential effect of local agro-environmental policies in promoting multifunctionality in a rural landscape, with a two-scale modelling framework: a regional scale for food demand and a local scale for the forces driving land use. The framework has been designed in four steps. First, the relative influence of the driving factors on the current land use pattern has been analysed. Two scenarios are designed that vary the external demand for the total land use, and alter more or less quickly the specific location factors that drive the landscape pattern. The first scenario considers trends in the external and internal driving forces. The second relies both on totally decoupled farm subsidies and unregulated housing growth. In both scenarios a local agro-environmental policy is introduced and we compare its consequences with the previous scenario's landscape pattern. The third step consists of a modelling exercise that analyses the likely outcome of each scenario on the development of land use patterns on a local scale. Last, these landscape patterns have been translated into ecological indexes that assess the effect of the policy options on the multifunctionality of the local landscape. 相似文献

Publicly available statistics regarding rural demographics, rural society and land use are presented and analysed using Geographic Information System (GIS). Our aim was to provide a quantitative basis for discussion of rural policy issues such as urban encroachment. Productivity (tonnage) of crop agriculture has increased by about 230% over 40 years while that of livestock (expressed as livestock units) has remained constant. Agricultural consolidation and intensification seen in southern Ontario has not translated into economic sustainability where on-farm income declined from 1991 to 2000. However, on-farm income in southern Quebec and municipalities adjacent to Toronto increased, perhaps due to the niche markets created in these regions. The increases in agricultural activity throughout southern Ontario have occurred in regions that have been designated as sites for innovation clusters, thus providing a foundation of resources for bio-based industries to expand and innovate. Reflecting on trends of demographics and production systems we conclude that rural policy should orient its geographical delineation to regional and inter-provincial scales. Our analysis indicates that rural populations and communities are sustainable but agricultural enterprises have changed radically; they have maintained or increased productivity but lost profitability. Applying a rural landscape design to the entire region would help address the sustainability of agriculture and rural communities. 相似文献

Farmer-specific relationships between land use change and landscape factors: Introducing agents in empirical land use modelling 总被引:1,自引:0,他引:1
Traditional empirical land use change models generally assume one average land use decision-maker. Multi-Agent System (MAS) models, on the other hand, acknowledge existence of different types of agents, but their poor empirical embedding remains a serious handicap. This paper demonstrates how agent information can also be incorporated into empirical, biophysical land use models. 相似文献

With growing awareness of fire hazard as an environmental threat within tropical rainforests, the state of Brazil initiated a set of fire control policies aimed at monitoring and ameliorating fire hazard in the Amazon region. These policies were developed in the aftermath of large-scale fire events and reflect a conservationist discourse that responded to internal as well as international environmental concerns. In doing so, the policies have framed the “fire problem” around those who use fire in their land use practices, in particular small-scale agriculturalists. Yet, land policy in general has repeatedly failed to address the institutional arrangements which compel small-scale farmers to use fire in their agricultural practices and the underlying development processes that have made the landscape more vulnerable to accidental spread of fire. Using regional level data on small-scale farmers, I suggest that the conservation oriented approach of fire policy may not be enough to curtail accidental fire events and instead that the fire issue needs to be positioned within rural development as well. 相似文献

This paper presents the updated findings of a series of research studies conducted within the last seven years by the author on the problem of current informal development in five southeastern European countries with varying political and cultural backgrounds: Montenegro, Albania, Former Yugoslavia Republic of Macedonia, Greece and Cyprus. The paper briefly reviews the main complexities and the variables associated with the issue in an effort to identify how these economies currently respond to informality in terms of regulations, priorities, and legislative and political approaches. It briefly investigates the causes, extent and impact of the problem and it analyses the adopted formalization policies with a purpose to identify good practices and remaining weaknesses. 相似文献

Changes in land use, land tenure, and landscape fragmentation in the Tijuana River Watershed following reform of the ejido sector 总被引:4,自引:0,他引:4

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

This article deals with the Israeli land policy in light of a certain judicial decision made by the Israeli High Court of justice (HCJ). A decision known as the “Land decision” (2002). Following the concept of shared mental models I will claim that the ruling of the HCJ at the given point in time expresses societal preferences formed through a process of learning through which society develops a shared mental model of ‘alternative behavior’ that reflects the way in which individuals and groups adapt to solve the social problems they face in various contexts. This shared mental model provides a frame of reference for the actions of political players such as politicians, special interest groups as well as the Supreme Court in shaping the design and implementation of Israel’ land policy. However regarding the Israeli land decision the ability of the Supreme Court to determine policy is limited on the implementation level. 相似文献

Strategies to increase agricultural productivity and reduce land degradation: evidence from Uganda 总被引:3,自引:0,他引:3

This paper estimates a structural econometric model of household decisions regarding income strategies, participation in programs and organisations, crop choices, land management, and labour use, and their implications for agricultural production and soil erosion; based upon a survey of over 450 households and their farm plots in Uganda. Many factors have context-specific impacts and involve trade-offs between increasing production and reducing land degradation. Government agricultural extension and training programs contribute to higher value of crop production in the lowlands, but to soil erosion in the highlands. By contrast, non-governmental organization (NGO) programs focusing on agriculture and environment help to reduce erosion, but have less favourable impacts on production in the lowlands. Education increases household incomes, but also reduces crop production in the lowlands. Poverty has mixed impacts on agricultural production, depending on the nature of poverty: smaller farms obtain higher crop production per hectare, while households with fewer livestock have lower crop production. Population pressure contributes to agricultural intensification, but also to erosion in the densely populated highlands. Several household income strategies contribute to increased value of crop production, without significant impacts on soil erosion. We find little evidence of impact of access to markets, roads and credit, land tenure or title on agricultural intensification and crop production and land degradation. In general, the results imply that the strategies to increase agricultural production and reduce land degradation must be location-specific, and that there are few 'win-win' opportunities to simultaneously increase production and reduce land degradation. 相似文献

Rural landscapes in many parts of the world are experiencing increasing pressure from competing uses. One particular use, unconventional natural gas extraction, has received considerable attention over the past decade owing to its rapid growth and associated impacts on rural landscapes. This study examined how a sample of Australian rural residents experienced the processes of psychological stress induced by a coal seam gas project that created perceived undesirable changes to resources they valued. Its effect on residents’ psychological well-being slowly unfolded over several years. We deconstructed the stress processes by investigating primary appraisal, secondary appraisal, and subsequent emotional and coping responses guided by the cognitive theory of stress and coping. Primary appraisal measured how the impacts of change on personal and communal resources were assessed while secondary appraisal gauged the options available to individuals to cope. Our results show that when primary appraisal alerts individuals of resource loss, negative emotions are more likely experienced. Such an appraisal directly drives engagement in eight coping strategies classified into four categories: problem-focused, support-based, emotion-focused, and maladaptive coping. It also motivates coping indirectly except for one strategy of emotion-focused coping mediated by negative emotions. While secondary appraisal also directly contributes to four coping strategies that each pertains to one of the four coping categories, it has no effect on negative emotions and four remaining coping strategies that are emotion-focused and maladaptive. These findings shed light on our understanding of the psychological consequences of undesirable change of land use on rural communities. Implications for land use policy are discussed with an emphasis on the need for considering a holistic perspective on the multi-dimensional nature of rural resources valued by community residents and establishing procedural fairness and legitimacy for proposed changes. 相似文献

Multifunctionality of agriculture: an inquiry into the complementarity between landscape preservation and food security 总被引:2,自引:0,他引:2

Without support, the levels of agricultural public goods suchas food security and landscape preservation would fall shortof demand in high-cost countries. However, as demonstrated byNorway as a case study, the current level of support is disproportionatefrom a public goods perspective, and the policy instrumentsare badly targeted at the public goods in question. Becauseagricultural land is a major component of both food securityand landscape preservation, giving rise to a high degree ofcost complementarity between the public goods, it would be moreefficient to support land-extensive production techniques thanproduction per se. 相似文献

Landscape is defined by the European Landscape Convention as “an area perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Many efforts have been devoted in addressing the core concepts on which this definition roots: perception and interaction of men and nature, but when coming to large (continental) scale assessments, the latter prevail on the former.This paper aims at presenting a framework for a measurable landscape awareness indicator as a key link to the public demand for a specific type of landscape: the agricultural landscape. This is a necessary effort to complement more physically based assessments, which include as well the impact of human activities on landscapes.The analysis is carried out at different levels of governance: EU and regional, using an example from the Alentejo region in Portugal and EU wide databases, and addresses conceptual and practical questions: what type of societal landscape awareness can be monitored and by whom (e.g., individuals, specific social groups, society as a whole); what are the landscape dimensions that should be assessed; what are the limitations imposed by data-related constraints. By applying the methodology to build composite indicators to map landscape societal awareness, the paper shows the regional and local meaning of indicator approaches developed at European level, presents developments for downscaling to regional level, while introducing the social component to support sound policy development for European rural landscapes. 相似文献

This paper examines whether the land consolidation (LC) practised since the 1950s in Galicia, N.W. Spain, has had the desired effects. To achieve this aim, we have adopted the methodology drawn up by the European Union for evaluation of its socioeconomic programmes, and we have adapted it as required by the subject matter and by the long-term historical perspective of this study. Our results suggest that, during the study period, LC has in general made a positive contribution to slowing rural depopulation. 相似文献

In the 21st century, the U.S. has experienced a boom in unconventional oil and gas development (UOGD). In part due to advances in technology, this rapid increase in UOGD has moved extraction practices into geographic areas that have previously seen little or no oil and gas development. As a result, conflicts over property rights have erupted—particularly in relation to split estate situations. To understand this controversy, we must situate it in the conditions which have shaped land use and mineral rights. We argue that past federal and state level governance decisions have created the conditions for UOGD conflicts today. Here, we utilize historical institutionalism (HI) to review the historical actors, processes, and institutions that have shaped how mineral rights have developed in the context of split estates in the U.S. We suggest that tracing this legislative and judicial history through HI is an essential foundation for exploring issues related to UOGD. Most importantly, we highlight these processes of governance as a bedrock for understanding spatial inequality inherent in current split estate law that grants the mineral estate dominance over the surface estate. We suggest that this codification of spatial inequality is problematic both in and beyond the context of split estates in UOGD. 相似文献

The rate and location of cropland expansion onto cattle pastures in Brazil could affect global food security, climate change, and economic growth. We combined mapping, statistical modeling, and qualitative methods to investigate patterns and processes of pasture to crop conversion (P2C) in Mato Grosso State (MT), Brazil, a globally important center of agricultural production. P2C land constituted 49% of cropland expansion from 2000 to 2013. For a random sample of ̃250 m pixels in MT, we estimated a regression model skilled at predicting P2C land in the rest of the state as a function of cattle ranching suitability, cropping suitability, and P2C conversion costs. Surprisingly, just 1/7 of pasture agronomically suitable for cultivation had undergone P2C. Hedonic regressions revealed that agronomic characteristics of land were associated with less than 20% of the variation in cropland suitability. Instead, the majority of the variation stemmed from a combination of proximity to agricultural infrastructure, characteristics of neighboring lands, and time fixed effects. The weak relationship between agronomic characteristics of land and P2C location suggests a less certain future for P2C than projections made with agronomic models. Consequentially, complications may arise for greenhouse gas mitigation policies in Brazil predicated on widespread expansion of cropland on pasture vs. natural areas. Our follow-up qualitative research shows that because P2C has often involved land rentals or sales, poorly functioning land institutions may have constrained P2C. Locally poor land quality, omitted from agronomic P2C predictions, can either catalyze or constrain P2C by limiting returns to ranching, farming, or both. Interventions to control rates and locations of P2C should take these insights into account. 相似文献

Private, not-for-profit land trusts have become major players in U.S. conservation efforts in the last 50 years. During this period membership in land trust organizations has grown. Despite the expansion of land trusts and land trust membership, little is known about public attitudes and beliefs about these organizations. To address this gap, we fielded a mail survey to members of a regional land trust in Indiana and a sample of nonmembers that reside in the areas served by that organization. In addition to examining differences in land trust members and nonmembers in terms of their demographic characteristics, recreation habits, awareness and use of land trust properties; we examined land trust beliefs and attitudes. Drawing from recent developments in attitude theory, the study employed a two-dimensional/bivariate model that allowed us to assess attitudes and distinguish between two forms of neutral attitudes toward land trusts – ambivalence (equal positive and negative feelings) and indifference (lack of any feelings). The study results indicated that, on average, land trust members were slightly older, better educated, and had lived in the area for shorter period of time than nonmembers. Members were also more likely to engage in non-consumptive outdoor activities like hiking and bird watching, while nonmembers were more likely to fish and hunt. Members also tended to have more positive attitudes toward land trusts and were more likely to express positive associations with land trusts. Nonmember attitudes demonstrated greater variability; specifically compared to members, nonmembers were more like to hold indifferent, ambivalent, or negative attitudes toward land trusts. Additional analysis comparing these three non-member groups provided insight into differences in their behaviors, knowledge, and underlying beliefs. We conclude with a discussion of the implications for organizational policy and outreach efforts. 相似文献
