Alternative crops, combined with modern farming methods, are integral parts of the new agricultural model and dominant priorities of agricultural policy. The new conditions created in the internal and global markets of agricultural products indicate significant opportunities for growing alternative crops and for the introduction of modern farming practices and processing. The present study aims to assess the factors that determine the landholder’s decision to uptake an alternative crop. Primary data were gathered through a quantative survey (in-depth interviews) with landholders in two remote and less-favored prefectures of Northeastern Greece, and were analysed through a logistic regression model. The results indicate that the most significant determinants for adopting an alternative crop involve the scientific support to farmers, the development of product demand in the market, the creation of agricultural cooperatives, the development of promotional campaigns for the alternative products, the education and knowledge regarding alternative crops, and the landholder’s satisfaction with income. On the contrary, negative factors to their decision refer to exports development, product subsidies, landholder’s age, membership to a cooperative in its current form, and satisfaction with pesticides prices. Despite the dominance of conventional agriculture models and varieties, the new favorable investment conditions can spur the promotion of alternative crops.  相似文献

In China, the planning quota, i.e., the binding target of construction land (BTCL) in land use planning for 15 years (2006–2020), was exhausted within only 7 years, which represents a very serious problem. This result not only nullifies the meaning of the plan itself but also threatens China's food and ecological security and poses great challenges to sustainable development. Here, we develop an analysis framework for local governments that break the BTCL in view of the strategic interactions of transferring newly increased construction land (NCL) among local governments and perform an empirical analysis of data on 262 prefecture-level cities from 2007 to 2016. The two main conclusions are as follows. First, adjacent local governments engage in positive strategic interactions regarding the quantity of NCL transferred. Second, positive strategic interactions regarding the quantity of NCL transferred are important reasons why local governments break the planning quota. In addition, we find that better economic development corresponds to more obvious positive strategic interactions. We also find that fiscal incentives and land misallocation play a significant role in promoting the increase in NCL, while strengthening land law enforcement can effectively constrain the increase in NCL. This paper enriches the literature on the reasons for planning failures, extending the research perspective to the level of interaction effects among local governments, and this paper provides new evidence regarding the strategic interaction among Chinese local governments. Moreover, this paper provides an important new path for the central government to constrain urban land expansion and to control the behavior of local governments that break the planning quota.  相似文献

Economic reform in China has resulted in rapid urbanisation over the past three decades, changing the urban and rural landscape dramatically. A large amount of farmland was developed, leading to conflict between construction demand and farmland protection. In response, the “Link Policy” was proposed in 2005 that seeks to concurrently preserve farmland while providing for urban expansion through land exchange. The effectiveness of the Link Policy has not been systematically investigated. The purpose of this study is to analyse and evaluate outcomes of the Link Policy objectives from both a participant and investigator’s interpretive perspective. Ezhou, the first experimental city to implement the Link Policy in Hubei Province in central China, was selected as a case study area. Eight different communities in Ezhou were visited and 160 semi-structured interviews were conducted with resettled rural residents in March 2016. A combination of interviews and investigator field observations were used to evaluate the Link Policy objectives. The results show that participants recognize and support improving rural living conditions and coordinating urban-rural development, but the Link Policy failed to achieve the objectives of preserving farmland, protecting farmers’ land use rights and interests, and facilitating agricultural production. Participants perceived concentrated resettlement communities to be more efficient in land use compared to more expansive rural settlements, but vacant apartments for commercial use in resettlement areas account for a large proportion of land suggesting inefficiency in the land exchanges. We suggest policy changes to achieve more successful implementation of the Link Policy.  相似文献

The increasing number of national high-tech zones (NHTZs) in China has triggered significant changes in land use. Several researchers argued that urban land use efficiency (ULUE) may decrease, due to the so-called “development zone fever”. However, using a super-efficient Slacks-based measure (SBM) model and the Double-difference model, we found that, from the perspectives of scale, factor accumulation, and agglomeration effects, NHTZs policies had a positive impact on ULUE in 285 Chinese cities in the period 2003–2016. In addition, the net effects of NHTZs policies on ULUE were 1.13 % in eastern cities, 0.38 % in central cities, and 0.19 % in western cities. Furthermore, different regions experienced differential impacts from economic development, urbanization level, industrial structure, population, foreign direct investment (FDI), and land marketization. A further empirical test found that the cumulative impacts of NHTZs policies on ULUE are related to both quantity and time. Among these, NHTZs growth time had the highest positive impact on ULUE. This study provides empirical justification for the establishment of NHTZs in China.  相似文献

Land consolidation plays an important role in increasing cultivated land, improving cultivated land quality and the ecological environment, and promoting the coordinated development of urban and rural areas. However, under the conditions of three decades of land consolidation being conducted and changing urban–rural human–land relationship, the areas of improvement in the land consolidation policy of China must be studied. This article analyzes the implementation and distribution characteristics of the land consolidation project completed in Shaanxi Province in 2018. Results show that land consolidation projects in Shaanxi are mainly land reclamation projects, cropland consolidation projects, and high-standard cropland consolidation projects. The increased cultivated land is mainly from land reclamation projects and cropland consolidation projects. The land consolidation projects in Aeolian Plateau Area, Loess Plateau Area, and Da Ba Mountain Area are mainly land reclamation projects. The land reclamation projects in Guan Zhong Plain Area and Qing Ling Mountain Area account for a large proportion. The spatial distribution of rural settlement consolidation projects, and rural settlement consolidation and land reclamation projects are mainly located in Guan Zhong Plain Area and distributed in the boundary area of Guan Zhong Plain Area and Loess Plateau Area. According to the characteristics of land consolidation projects and the changes of urban–rural human–land relationship, China should be prudent in or stop advancing land reclamation to increase cultivated land; cropland consolidation and high-standard cropland construction are vital ways to achieve China’s food security; and rural settlement consolidation should be carefully conducted in remote areas under the background of urbanization.  相似文献

Farmers are decision-makers in a complex system of cause and effect. They decide with respect to their own attitude and beliefs, according to their farm structure and they take into account programs and regulations of the overarching policy scheme. In this paper we used mail surveys with identical questions to establish a cross-national comparison of two case study areas. The questionnaire investigates farmer's perspectives on what influences their own decision-making as well as their perception of the socio-ecological environment to relate these findings to the respective policy schemes in the case study areas. The two case studies are located in Southern Illinois, United States and in central Switzerland. The analysis shows that full-time farmers of the Southern Illinois case study area rate constraining factors such as financial aspects higher than Southern Illinois part-time farmers and farmers from the central Switzerland case study area. Furthermore, it is apparent that Swiss case study-farmers rate aspects of their land use responsibility and the Illinois case study-farmers rate ecological aspects higher. The empirical findings can be qualitatively explained through analysis of agricultural policy schemes.  相似文献

In the past few decades, urbanisation has become a major phenomenon in European cities, thus representing one of the key human land cover changes with socio-economic and environmental impacts. In the Lisbon metropolitan region it is estimated that 17% of natural and farmland have been transformed into artificial areas. Since the end of 1990s, specific EU guidelines have been issued to contain urban sprawl and preserve agricultural land. Spatial planning in Portugal obviously is integrating these assumptions into the statutory land-use master plans. But what is the performance of this land use planning system regarding land cover evolution itself? Based on the Lisbon metropolitan region (LMR), one of the major areas of urban growth in Portugal, we examine spatio-temporal land cover patterns between 1990 and 2007 by integrating cross-matrix analysis, spatial metrics, and gradient analysis. Additionally, we overlay these land cover dynamics with municipal master plans that regulate land development in order to assess the compliance levels of this land-use regulatory system. Results indicate that: artificial areas are growing by coalescence and/or by scattered development along an urban–rural gradient; agricultural land is reducing and fragmentation is increasing to enlarge peri-urban spaces; there are high levels of conversion of agricultural land into urban land in protected areas, thus showing a lack of compliance to the land use regulatory system visible in the existing gaps between the original land-use assignments of the master plan and the actual developments.  相似文献

Grassland conversion to row-crop production in the north central United States has been a growing threat to socio-economic and environmental sustainability for producers, conservationists, and policy-makers alike. We used a system dynamics model of the region to forecast agriculturally driven land transformation through mid-twenty-first century. The base-case scenario projection showed that farmland area continued to increase, from under 200,000?km2 to over 230,000?km2. Unmitigated, the soil environmental risk (SER) of such changes reached conservative estimates of Dust Bowl-era externalities. Systems analyses show that reducing livestock production costs, doubling conservation compliance requirements, and livestock–cropping integration had the largest impact on grassland conservation and mitigating SER. The largest SER effects came from eliminating conservation incentives or raising cultivation incentives, despite improvements in reduced tillage and enhanced agronomy. Several system archetypes were identified within the policy scenarios: ‘fixes that backfire’ and ‘success-to-the-successful’. For scenarios creating favourable impacts, time delays caused some behaviours to worsen before positive gains were realized. If implemented, patience and persistence to ensure that these scenarios reach their full potential will be necessary. Our scenarios provide quantitative forecasts around measures for sustainable intensification. These projections can aid regional stakeholders in enhancing discussions currently taking place about sustainable agriculture in the region.  相似文献

Landowners are the key players in bioenergy production on wasteland; such as cutaway peatlands. In this study, the landowner’s interest to use cutaway peatlands for bioenergy production was investigated using a survey and GIS (Geographic Information Systems) methods in an area in South Ostrobothnia, Finland. The focus was to identify which different bioenergy production chains are preferred by the respondents: combustion, gasification or biogas production from agriculture, energy-willow short-rotation forestry or forestry based energy crops. Also, the influence of personal environmental values on the selection was measured and the future impacts and barriers for the land use were assessed.Afforestation was the most popular after-use method among the landowners. The next most favorable method was energy crop cultivation but it was highly dependent on economic profitability and subsidies. Currently, approximately 8.2% or 500 ha of the total peat extraction area could be used for bioenergy production in the region by 2035. Based on the survey, forest based biomass is the best option if bioenergy is to be produced. The next choice was agro biomass and the least favored plant was willow. This study suggests that the biggest cutaway peatlands will be converted to forest energy in the future. Suggestive results were that the owners with high environmental values are especially interested in agro biomass growing and the landowner having a distant home place does not have a negative influence on bioenergy production. Altogether, land use and biomass production of cutaway peatlands is connected with the demands of the Finnish bio-economy.  相似文献

Improvements to forest and land governance are key to addressing deforestation and degradation of peatlands in Indonesia. While this is a priority area, the steps to achieving good forest and land governance have been under-researched. There is a need for better links between theoretically informed academic analysis and work in the field. This study drew together a panel of experts on forest and land governance using a Delphi method to discuss the underlying drivers of deforestation and peatland degradation, and correspondingly, to identify interventions to improve land and forest governance in Indonesia. Seventeen panelists with an average of more than 12 years’ experience reached agreement over four governance interventions: increasing the capacity of local communities to manage and monitor forests and natural resources (65% of panelist’s votes); identify strengths and weaknesses of community organisations and institutions, and develop strategies to improve their performance (65% of panelist’s votes); gazetting forests to clarify land boundaries and determine which areas should be village, community and state forest zone (59% of panelist’s votes); and, integrating participatory community maps into spatial plans to protect local communities and indigenous peoples’ development needs (53% of panelist’s votes). They also supported action research involving the government, private sector and communities, and political economy approaches to researching forest and land governance issues. Panelists indicated that community level approaches such as securing community forest tenure through clarifying land claims and integrating local land tenure into spatial planning had an important role in sustainable forest management.  相似文献

The relationship between forests and people is of substantial interest to peoples and agencies that govern and use them, private sector actors that seek to manage and profit from them, NGOs who support and implement conservation and development projects, and researchers who study these relationships and others. The term ⿿forest-dependent people⿿ is widely used to describe human populations that gain some form of benefits from forests. But despite its long history and widespread use, there are substantial divergences in who the term refers to, what each of its constituent words mean, and how many forest-dependent people there are globally. This paper identifies the range of existing uses and definitions of the term ⿿forest-dependent people⿿, and summarizes them in a systematic taxonomy. Our taxonomy exposes the dimensions that characterize the relationships between people and forests, and leads to two conclusions: First, an absolute, universally accepted definition of the term is untenable. Rather, users of the term ⿿forest-dependent people⿿ need to comprehensively define their population of interest with reference to the context and purpose of their forest- and people-related objectives. The framework and language of our taxonomy aims to aid such efforts. Second, conservation and development program funders, designers, and implementers must reconsider whether forest dependence is an appropriate target for policy objectives.  相似文献

This paper provides an original accounting of changes in livestock production efficiency per livestock category in historical perspective and connects livestock consumption with land requirements and virtual land trade. We use France as a demonstration study and account for productivity changes in terms of energy. Feed rations composition are reconstructed per livestock production and feed crop group over time to account for changes in land use in relation to dietary changes. Land requirements for consumption in France dropped by 28% over the study period besides an increase by 35% of the human population and by 53% of the livestock consumption. The two-fold increase in agricultural productivity is due, for half, to energy conversion efficiency improvements and for half to agricultural yields. Overall, the livestock energy conversion efficiency increased by 45% from 1961 to 2010, poultry gained 84%, pork 17%, sheep&goat 67% and cattle 27%. The feed share of oilcrops and cereals in animal rations doubled against a drop by 35% of feed from pastures. Virtual land imports for oilcrops in relation to livestock consumption in France today amount to 0.9 million ha against a maximum of 1.9 million ha in 1979. Besides its dependence on oilcrops imports, the French livestock sector displays net virtual land exports ranging from about 2.5–5.3 million ha per year over the study period. Gross virtual land trade is today five times higher than the net virtual trade. The difference highlights the share of circular product loops in increasingly integrated agricultural markets at the international scale.  相似文献

Wild mushroom picking is a growing recreational and commercial activity. In Spain, wild mushrooms legally belong to the landowner, who seldom benefits from trade in mushrooms or from their recreational value. Cultural aspects (tradition, picker-related harms) and economic aspects (costly forestry works, income opportunities) constitute elements of the debate on how to deal with mushroom picking. Through a survey of private forest owners in Catalonia (north-eastern Spain), this paper examines their experiences with mushroom pickers, the factors shaping their related policy preferences and their willingness to engage in mushroom reserves.The results show broad support for introducing mushroom picking norms. A regulation would allow outsider pickers to enter private land, but only under certain conditions, i.e. to comply with socio-ecological rules of the area. Among respondents who support the regulation, active land owners who report instances of picker-related harm (both tangible and intangible) tend to support the establishment of a fee system which could be reinvested into forest management. That is also the position of the respondents who perceive mushrooms as a private right, i.e. they believe to have a legitimate right to exclude outsider pickers and, eventually, to raise revenues from that asset. On the contrary, forest owners who conceive mushroom picking as a free-access activity prefer neither to regulate it nor to charge fees. The option to establish a mushroom picking reserve depends on the landholder being a fee-supporter and perceiving instances of harm. Harm, instead, is mainly determined by the perception of congestion of pickers, which in turn is determined by the mushroom productivity of their forest, their level of privacy protection and their involvement to the primary sector. These findings help policymakers to better understand the logic and sensitivities of forest owners in view of designing mushroom picking policies that can effectively solve picker-landowner conflicts.  相似文献

Coastal zones with their natural and societal sub-systems are exposed to rapid changes and pressures on resources. Scarcity of space and impacts of climate change are prominent drivers of land use and adaptation management today. Necessary modifications to present land use management strategies and schemes influence both the structures of coastal communities and the ecosystems involved. Approaches to identify the impacts and account for (i) the linkages between social preferences and needs and (ii) ecosystem services in coastal zones have been largely absent. The presented method focuses on improving the inclusion of ecosystem services in planning processes and clarifies the linkages with social impacts. In this study, fourteen stakeholders in decision-making on land use planning in the region of Krummhörn (northwestern Germany, southern North Sea coastal region) conducted a regional participative and informal process for local planning capable to adapt to climate driven changes. It is argued that scientific and practical implications of this integrated assessment focus on multi-functional options and contribute to more sustainable practices in future land use planning. The method operationalizes the ecosystem service approach and social impact analysis and demonstrates that social demands and provision of ecosystem services are inherently connected.  相似文献

Competition among different uses for land is becoming acute under the process of urbanization, and conflicts related to this competition are becoming more frequent and more complex. This article presents a methodology for confronting this issue. By applying an integrated framework, we explore the implicit role of the Beijing–Tianjin–Hebei Regional Integration (BRI) policy in land use conflicts by focusing on the urban-rural interface, and try to address the research question: “How feasible is BRI for reconciling land use conflicts across the urban-rural interface?” An original structure of the analysis is developed based on the identification of three types of conflicts, namely, conflicts over land use structure, conflicts over land conversion and conflicts over landscape pattern. According to the interactions and relationships among these conflicts, we define broad categories of land use conflict areas. Indeed, these conflicts are all related to the unplanned use of agricultural land reserves, which competes with other more immediate uses, and the over-exploitation of land resources caused by unsustainable urban practices. This policy is clearly a critical objective for optimizing the land use structure. It, however, fails to reconcile the conflicts over land conversion and landscape pattern, especially for considerable agricultural land conversion to non-agricultural uses, and low-density development pattern with mixed residential and industrial land uses. Hence, alternative strategies involving public participation, spatial equity, rural revitalization, land-use system reform, and new type of urbanization, can be identified as viable solutions for land use conflict management, which may be complementary to regional integration. The findings of our paper may also contribute to the policy debate on BRI concerning land use planning and regional sustainability.  相似文献

While various attempts have been made to establish strategic environmental assessment (SEA) processes and institutions in various jurisdictions within Australia, the success of these often short lived attempts at institutional approaches for managing public land use conflict has been patchy. The experience in the State of Victoria has been somewhat different, with public land use assessment and planning having been informed by a series of independent statutory bodies since 1970 (the Land Conservation Council, Environment Conservation Council, and Victorian Environmental Assessment Council). These SEA bodies have played a major role in mediating environmental conflict over public land use, and have significantly contributed to the increased size and coverage of Victoria's protected area system. However, while there has always been a statutory body in operation, the roles and responsibilities of these bodies have been subject to significant legislative change, with existing bodies replaced by new bodies in 1997 and 2001. Justifications for these reforms included changing circumstances and new understandings about environmental management, as well as changing views about public administration. As a way of contributing to enhancing the design of institutions and processes for strategic environmental assessment, this paper provides an assessment of Victoria's approach and discusses possible future directions.  相似文献

Soils form a major component of the natural system and their functions underpin many key ecosystem goods and services. The fundamental importance of soils in the environment means that many different organisations and stakeholders make extensive use of soils data and information in their everyday working practices. For many reasons, stakeholders are not always aware that they are reliant upon soil data and information to support their activities. Various reviews of stakeholder needs and how soil information could be improved have been carried out in recent years. However, to date, there has been little consideration of user needs from a non-expert perspective. The aim of this study was to explore the use of explicit and hidden soil information in different organisations across Europe and gain a better understanding of improvements needed in soil data and information to assist in practical use by non-expert stakeholders. An on-line questionnaire was used to investigate different uses of soils data and information with 310 responses obtained from 77 organisations across Europe. Results illustrate the widespread use of soil data and information across diverse organisations within Europe, particularly spatial products and soil functional assessments and tools. A wide range of improvements were expressed with a prevalence for finer scale resolution, trends over time, future scenarios, improved accuracy, non-technical supporting information and better capacity to use GIS. An underlying message is that existing legacy soils data need to be supplemented by new up-to-date data to meet stakeholder needs and information gaps.  相似文献

In the context of climate change, adaptation to climatic extremes, such as drought, has attracted worldwide attention, yet many practical adaptation strategies need to be examined at the local level. Based on a case study of the village of Beidian, located in a drought-prone region in northern China, this study demonstrates that when faced with multiple pressures of regional climate change, drought risk and rural poverty, reasonable adjustments in land use patterns can serve as an effective adaptation strategy in the agricultural sector. We used household questionnaires, in-depth interviews with village managers, and land use surveys at the farming plot level to quantify the relationship between land use change and drought mitigation effects. Our findings indicate that in the past decade, the farming practices in Beidian have transformed from a complete reliance on the winter wheat–summer corn rotation to a new diversified mode of apple as the main crop and corn and coarse cereals as the subsidiary crops. The current farming mode is proven to possess a stronger adaptive capacity to drought due to its higher water-saving efficiency and economic benefit, which facilitates rural poverty reduction and socio-economic development. This study presents a feasible approach to address adaptation strategies at the local level, which provides policymakers with information on how to best support farm-level adaptation and to reduce farmers’ vulnerability to climatic extremes within the broader context of climate change.  相似文献

Creative hotspots have become a key driver for urban policies to stimulate social, cultural, environmental and organisational growth of creative and knowledge-based clusters, districts and hubs. However, their functional and spatial characteristics vary due to their different evolving structure as new spaces of economic activity in different contexts. This article points to a consideration of new foci for both land use and urban economic policy through a mapping of formal and informal creative hotspots in Brisbane, Australia. The study found two distinctive development patterns: (a) earlier top-down approaches as instigated by national and international innovation policies, and; (b) recently emerging bottom-up spaces for creativity, knowledge and innovation practices. This study examines how formal creative strategies and emerging informal creative spaces shape cities and urban policies. The methodology comprises online data collection and a review of creative and knowledge strategies and implementation policies. Data was then analysed via multiple mapping techniques illustrating the spatial distribution of creative hotspots, formal and informal formations, scale and land use characteristics. The research findings consolidate our understanding of Brisbane’s creative ecosystem and suggest new urban policy mechanisms to better foster the interrelationship between top-down and bottom-up approaches in cities, that is, between formally planned and large-scale interventions and small-scale organic and informal creative activities.  相似文献

The impacts of climate change on agriculture in developing countries will depend on the extent to which agricultural production in those regions adapts to climate change’s influences. This study uses a whole-farm land use optimisation approach to explore climate change impacts, when including adaptation, on farm profitability, production and associated greenhouse gas (GHG) emissions in the Loess Plateau of northern China. The results show that with adaptation activities, the losses in smallholder farm profitability caused by the climate change could be moderate. Declining rainfall results in land use changes that generate higher on-farm GHG emissions with the most economically beneficial adaptations. With 5 % or 10 % decline in annual rainfall, the introduction of agricultural carbon tax would generate substantial reduction in on-farm GHG emissions. With 30 % rainfall reduction, agricultural carbon tax is not likely to bring about considerable emission reduction. The economically optimised land uses are generally sensitive to potential changes. When rainfall reductions appear, there is a clear trend toward reducing cropping area and transiting to pasture. With 5–10% rainfall reductions, increasing agricultural carbon tax with same rainfall reduction leads to the expansion in cropping enterprises. However, with 30 % rainfall reduction, land allocations are not sensitive to agricultural carbon tax. When with declining annual rainfall, in the optimal enterprises more oats-pasture rotations are employed to reduce wheat dominated rotations. Besides land use patterns, adaptations through altering farm management practices are also necessary. The economically optimised sheep flock would be increased considerably with declining rainfall. Overall, policymakers are suggested to initial more educational schemes to tell smallholder farmers how to make the best use of available adaptation strategies and consider changes in climate when design and implement agricultural policy.  相似文献
