保障我国农民土地收益的制度分析

近年来，由于制度安排的缺陷，我国农地大量转非，农民利益受到损害，导致大量失地农民出现，危及粮食安全和社会稳定。当前，尽管中央对土地进行了严格管理，但是只是临时政策性的措施。要从根本上解决这些问题，必须从制度创新上寻求可行的途径。为此，本文通过对农民土地利益损失的制度原因分析，并对农地制度固化和创新的风险以及几种可供选择的制度创新方案比较后，认为渐进式的制度改革是符合我国的现实选择。

Policy instruments for curbing CO2 emissions: The case of the Netherlands

Taxes may seem to be the most attractive instrument for curbing the emissions of carbon dioxide. This paper, however, argues that environmental taxes involve a number of serious complications — especially in an open economy riddled with market imperfections like the Netherlands. Therefore, a wide-ranging policy mix is called for. As far as households and sheltered sectors are concerned, regulation can continue to play a major role. Within the context of unilateral policies aimed at exposed sectors, the combination of subsidies and voluntary agreements may be more cost effective than the tax instrument.This paper was prepared for a conference on Energy Taxation in Europe organized by the Stichting voor Economisch Onderzoek (SEO) and held on December 13, 1991 in Amsterdam, the Netherlands. The author would like to thank Sijbren Cnossen, Jarig van Sinderen and one anonymous referee for helpful comments on an earlier draft.     

Buyer-Type Effects in Conservation and Preservation Property Values

Properties can be bought by government agencies, land trusts, or private entities for conservation and preservation purposes, such as farmland preservation, wildlife refuges, other conservation, and cultural and historical preservation. There is variation in the dollars paid per acre across properties and across buyer type. An option value model based on future potential land uses is used to explain much of this variation. The data used in our analysis is sales transactions data for conservation and preservation purposes from throughout the United States. We find that much of the value of conservation properties is derived from future potential land uses, including housing, timber, recreation, and conservation. We confirm that public versus private buyers value options differently, which makes sense from a public good point of view, if markets are thin.     

Addressing the social landscape dimensions: The need for reconciling cross scale assessments for capturing Cultural Ecosystem Services (CES)

This special issue integrates eleven papers focussing on indicators able to convey the multiple expectations that society has concerning agricultural land. As scale issues have been so far overlooked within this research topic, a particular focus of this themed issue is to highlight the need for reconciling assessments across scales. The shared purpose of the contributions is to examine how the multiple societal expectations concerning agrarian landscapes might be incorporated into land use policy at different governance levels.A core set of these papers were presented in the symposium “Linking social indicators across scales”, to the European Congress of the International Association of Landscape Ecology (IALE) in September 2013 in Manchester, UK. This symposium was organized to create the time and space for a discussion on the issues of scale when capturing societal preferences concerning agrarian landscapes. While the landscape scale was specifically addressed by four papers, seven papers examined broader geographic units in addition to up-scaling and downscaling issues.     

Co-ordination of land exploitation,exploitable farmland reserves and national planning in China

Land exploitation, as an important strategy to mitigate farmland loss and stabilize grain production, has been adopted to compensate farmland loss due to rapid urbanization in China. Bounded by the limited capacity and obvious spatial variations of national farmland reserves, it is essential to arrange land exploitation activities timely and reasonably. In this study, we propose an indicator for the status of regional land exploitation, the Exploitation Degree, to facilitate an overview of land exploitation programs in China at both provincial and prefectural levels based on project data from 2006 to 2012. To further our understanding of the regional features of land exploitation activities, we employ the Lasso model to identify and quantitatively assess influencing factors on land exploitation. Our study shows that: (1) contemporary land exploitation practices in China are significantly inconsistent across exploitable farmland reserves. Some areas are greatly over-exploited and such irrational land exploitation has been persistent; (2) related national land plans designed to guide land exploitation efforts centered on resource-rich regions and critical areas do not function as intended. Therefore, we suggest that China⿿s land exploitation policy shall be improved by reconsidering the orientation of land exploitation policy, coordinating land exploitation activities with productivity improvements and eco-system protection, and enhancing the power and scope of the plans in controlling and guiding land resource management.     

Quantitative micro-scale flood risk assessment in a section of the Trotuș River,Romania

This paper focuses on the estimation of direct damages caused by three flood scenarios with different return periods in the section Făgetul de Sus – Ghimeş – Palanca Pass of Trotuș River, with the aim of highlighting the need of improved land use plans. The damage for three land use classes (residential building, infrastructure and agriculture) were estimated using the damage curves developed by the European Joint Research Centre (JRC) as well as site specific maximum damage values. The data were processed with the help of the ArcMap 10.2 software and FloodRisk tool from QGIS software. Furthermore, the flood risk was assessed using the damage – probability curves, which associates the damage with the corresponding frequency of occurrence. This method was identified and adapted to the characteristics of the study area in order to develop a methodology of flood risk assessment that is answering the question: does the lack of land use plans increase the vulnerability and the flood damage? The results showed that the greatest damages are registered for the residential building land use class for a flood probability of 0.001. In this case the damages reach up to 60% on the scale range of deterioration factor, the total damage value being 2 million euros. For the same hazard probability the total registered damage value for roads is 7500 euro, for railways is around 12,000 euro, while for agriculture is around 84,000 euro. These results highlight the need of protection measures and land use plans development and implementation. Regarding the protection measures we consider that the egalitarianism would be the concept that should be applied in the study area and also an improved cooperation between government, specialized agencies and local authorities at local level would lead to a more efficient flood risk management process. The proposed methodology can be applied for micro-scale analysis, providing quantitative results regarding the flood damage and flood risk assessment. It includes a detailed vulnerability analysis of the elements-at-risk with the aim of developing a more comprehensive approach of flood risk assessment.     

The living commons of West Tyrol,Austria: Lessons for land policy and land administration

A right of commoners to pastures existed since the Early Middle Ages in Anglo-Saxon England and the European mainland, including Tyrol in Austria. Lowland commons institutions were largely dissolved by the 19th century; however, in the European Alps contiguous commons remain alive. Some two thousand alpine commons institutions are registered in the Tyrolean parcel cadaster and land registry. A specific study of West-Tyrolean commons (known as Agrargemeinschaft or AGMs), framed by Ostrom's design principles is presented. General lessons for land policy and land administration are extracted. An interview period was split between the Inn valley and the Ötztal. Roughly half are considered independent: others are regulated by the Tyrolean Agricultural Authority. Some AGMs hold the full bundle of land rights: others only hold pastoral and forestry rights. AGMs consisted either of a single cadastral parcel or several contiguous parcels. In the Inn valley villages the pastoral commons were owned by the municipalities, while in the researched Ötztal, AGMs are frequently the full owners of the commons. AGM membership ranges between 5 and 60 farm households. The number of livestock units pastured was in most cases stipulated in approved regulations. Alpine commons larger than 200 ha are also hunting-zones: revenue is collected from the lease of hunting rights. Most of the alpine commons are designated and used as ski-zones. Upper portions of two alpine commons in the Ötztal are state protected natural areas. The number of farms with pastoral rights is declining at District and State level. Key lessons for land policy and land administration include: Ostrom's design principles being a precondition rather than a panacea; commons institutions requiring one clear ownership party; both public and collective ownership producing success; publically owned commons requiring a local representative; small membership numbers being preferable; small shareholdings not being preferable; decentralized governance being beneficial; internal democratic elections being beneficial; internal boundary records being superfluous; explicit sanctions being superfluous; mixed economies being acceptable; and geography being a significant influence on the longevity of pastoral commons.     

The ‘squeezed middle’: Identifying and addressing conflicting demands on intermediate quality farmland in Scotland

The growing demand for a wide range of private and public goods and services from a finite land resource is increasingly challenging for planners at local, regional, national and international scales. The Scottish Government's development of a Land Use Strategy has given salience to resolving conflicts and enhancing synergies in land use. In Scotland, the poorest quality farmland is often designated for nature and landscape conservation and the highest quality farmland often protected for food production. This means that many of the competitive pressures on land are experienced in what we term the ‘squeezed middle’. The paper identifies the multiple (and not exclusively economic) drivers of land use choices and, through an ecosystem services lens, explores three particular areas of land use conflict. These are (i) the continued high level of public support for farming, which has done little to address the problem of low farm incomes; (ii) the pressure to increase woodland planting on farm (and other) land; and (iii) conflicts associated with intensive game management, especially on sporting estates. Using the Scottish situation as an example, the heterogeneity of land use pressures means that there is a danger of the principles of the Land Use Strategy becoming lost in translation from national policy to practical land use decision-making. The appropriate scale for delivery of integrated ecosystem services may therefore be more local than current pilot projects, and may require more active participation of land managers. It may also require policy instruments that are more flexible in adapting to the local context, including payments for ecosystem services.     

How to overcome the implementation gap in ecosystem services? A user-friendly and inclusive tool for improved urban management

One of the main issues with the concept of ecosystem services is its absence on the ground in concrete operational decision-making contexts; that is, an implementation gap. In this study, we investigated if this gap could be overcome through the use of open-source data and free tools, and the adoption of a short-term participatory process. We tested these methods in the context of a project in the urban metropolitan area of Bordeaux (Communauté urbaine de Bordeaux: CUB) in France. The ecosystem services were defined using a participatory approach involving local stakeholders, and then selected scenarios were simulated to test the impact of various development or conservation plans. The study addressed three main questions: (1) Is it possible to adopt a simple methodological approach that overcomes the implementation gap through the development of a user-friendly and inclusive method? (2) What is the added value of a participatory approach? (3) With regards to four scenarios in this territory, what are the ES trends in the selected biophysical and monetary indicators, and will knowledge of these trends help planners to shape a sustainable trajectory for the territory?
