Analysing the Agricultural Costs and Non‐market Benefits of Implementing the Water Framework Directive

Implementation of the Water Framework Directive (WFD) represents a fundamental change in the management of water in Europe with a requirement that member states ensure ‘good ecological status’ for all water bodies by 2015. Agriculture is expected to bear a major share of WFD implementation costs as it is compelled to reduce the emission of diffuse water pollutants. The research outlined here comprises interdisciplinary modelling of agricultural land use, hydrology and consequent water quality effects to consider both agricultural costs and the non‐market recreational use (and potentially non‐use) values that implementation of the Directive may generate. A theme throughout the research is the spatial distribution of the costs and benefits of WFD implementation, which is addressed through the use of GIS techniques in the modelling of agricultural land use, the integration of land use and hydrological models, and the estimation, aggregation and transfer of the economic value of the benefits.     

淡水养殖系统环境损害成本的条件价值评估——以淀山湖水源保护区为例

水产养殖生态系统为人类提供了巨大的生态服务价值,但也造成一定程度的环境污染。本文利用CVM方法调查了淀山湖区域居民对水产养殖系统环境损害成本的支付意愿。分析结果表明,只有23.5%的居民对解决水产养殖造成的淀山湖生态环境损害存在支付意愿。利用单边界两分式问卷调查发现,对于水产养殖生态系统的环境污染治理的平均支付意愿为15.92元/人·年。据此计算,淀山湖周边三镇水产养殖系统的环境损害成本为每年276.7万元。居民治理水产养殖环境污染的支付意愿受收入、性别等社会经济因素的影响。     

Agri‐environmental auctions for phosphorus load reduction: experiences from a Finnish pilot

We examine environmental auctions on working agricultural lands. We organized a discriminatory auction where farmers were asked to make bids on spreading gypsum on their fields to reduce phosphorus loads to surface waters. The parcel‐specific bids were ranked based on their load reduction–compensation ratios. To assess load reductions, we built an environmental benefit index (EBI) based on three factors: P‐status of the soil (phosphorus available for crops), field slope and location with respect to waterways. As the per tonne price of gypsum delivery from the factory was higher for small quantities, the auction format allowed bundling of field parcels to reduce transportation costs. We evaluate auction's ability to target the environmental (or abatement) measures to field parcels with the highest load reduction potential and analyse the economic efficiency of the auction by comparing the pilot auction with simulated bidding behaviour and with hypothetical flat rate payment schemes. The pilot auction targeted the environmental measures effectively. It was also more efficient than a flat rate payment, even when the flat rate scheme was combined with an EBI eligibility criterion.     

Ambivalent statements in contingent valuation studies: inclusive response formats and giving respondents time to think

A recent concern in the valuation literature is the uncertainty respondents feel when posed with willingness-to-pay questions for environmental amenities in hypothetical market scenarios. Using a multiple-bounded discrete-choice format, the results indicate that respondents become less ambivalent when allowed considerable time to think about the valuation task before a response is elicited. In particular they tend to reduce the reported willingness to pay associated with low certainty of paying, hence resulting in more conservative welfare estimates. Implications for the application of environmental valuation techniques are discussed.     

Zionism and agricultural land: National narratives,environmental objectives,and land policy in Israel

The 1990s saw two different and even contradictory trends in Israel. On the one hand, there was a substantial increase in environmental awareness, on the part of both the general public and decision-makers, that led to a change in the land use planning policy at the national level. On the other hand, the Israel Lands Council (ILC), the body empowered by law to shape the national land policy, made a series of decisions that severely violated the principle of preserving agricultural land and led to massive conversion of agricultural land and open space for commercial, industrial, and residential development. Thus the national land policy became incompatible with the land use planning policy and the rise in environmental awareness it reflected.     

Grain-for-green policy and its impacts on grain supply in West China

China's grain-for-green policy of converting steep cultivated land to forest and grassland is one of the most important initiatives to develop its western inland regions. Using a multi-objective programming model, this study assessed the impacts of this policy in the upper reaches of the Yangtze River and the upper and middle reaches of the Yellow River. In addition to the strategic planning of converting cultivated land to forest and grassland and its associated impacts, three other scenarios were simulated. Results showed that impacts on grain supply at the national level were in the range of 2–3%. These results suggest that the proposed policy might not have a major impact on China's future grain supply and the world grain market. At the local level, however, impacts could be significant.     

Equivalence of Input Quotas and Input Charges under Asymmetric Information in Agri‐environmental Schemes

A model of adverse selection and moral hazard in agri‐environmental schemes is developed based on the input quota mechanism of Moxey et al. (Journal of Agricultural Economics, Vol. 50, (1999) pp. 187–202) and Ozanne et al. (European Review of Agricultural Economics, Vol. 28, (2001) pp. 329–347), rather than the input charge mechanism of White (Journal of Agricultural Economics, Vol. 53, (2002) pp. 353–360), but the variable fine of the latter rather than the fixed fine assumed by Ozanne et al. (European Journal of Agricultural Economics, Vol. 28, (2001) pp. 329–347) is used. Incentive‐compatible contracts, including the optimal probabilities of detection (and, therefore, monitoring frequencies and costs) for more and less efficient farmers, are identified. It is shown that the input charge and input quota approaches lead to identical outcomes – in terms of abatement levels, compensation payments, monitoring costs and probabilities of detection – confirming the equivalence of input quotas and input charges under asymmetric information. It is also shown that the optimal contracts are independent of the risk preferences of farmers with regard to being caught cheating.     

Multiple criteria decision making in fisheries management: Experiences and implications

The management of renewable resources takes place in a paradigm where several (conflicting) objectives are relevant to take into account. This feature is shared with other fields of management, involving economic, environmental and social issues. Hence, it is natural to employ a management model incorporating multiple objectives in the decision process. Multiple criteria decision making (MCDM) has attained interest within a wide range of management fields. This article reviews applications related to fisheries. The purpose is to clarify how the different methodologies can contribute to management. It is hoped, this leaves the field of MCDM more tangible, visible and attractive to managers. It will be emphasized that an MCDM analysis can be carried out in many different ways and for different purposes, and that the outcome depends on the assumptions made.     

The incidence of agricultural policy on the land market in Poland: Two-dimensional and multilevel analysis

Research has shown that the reform of the CAP which broke the link between subsidies and production (the decoupling reform) has had little effect on farmers’ demand for land under the SPS (Single Payment Scheme) system. For this reason, in the conditions of the SPS, there is petrifaction of the structure of agricultural land, and an upward trend in prices on the market for agricultural land should not be expected to continue in the long term. Under the conditions of the SAPS (Single Area Payment Scheme), which applies in the EU-12 new Member States, the position in the market for agricultural land is different. However, most research carried out in Europe relates to the SPS system, where marginal changes in the value of land are identified as a result of the incidence of agricultural policy, as well as quantitative and qualitative attributes of particular properties. Under SAPS, these issues have not been sufficiently investigated. The authors have attempted to fill that gap, constructing a two-dimensional and multilevel econometric model for land prices in a leading agricultural region of Poland based on a sample of 653 transactions in the years 2010–2013. The aim is to determine how policy, as well as various quantitative and qualitative features, including location factors, affect the prices of land under SAPS. The results indicate, among other things, the key importance of the functional type of rural areas – properties in agrotouristic areas gained 43% higher prices on average than those in agricultural areas. Another finding of interest is that LFA and agro-environmental payments decapitalise the value of land.     

Trade and agroindustrialization in developing countries: trends and policy impacts

There have been important changes in the international trade of processed and high-value added food products from developing countries over the past several decades. One of them has been the emergence of oilseeds and fruits and vegetables, replacing traditional products such as sugar, coffee, and cocoa as the main exports from developing countries. Another trend has been the collapse of African agroindustrial exports and the increase of exports from Asia. The paper highlights key trends, and explores possible reasons for the trends, focusing on trade policies in less-developed countries (LDCs) and developed countries (DCs). The paper argues that national trade policies and other economic policies appear to have been relatively supportive of agroindustrial production and exports in Asia. In contrast, policies have had more mixed effects in Latin America and the Caribbean (LAC), and seem to have been just one component in a larger array of forces inhibiting economic development in Africa. The performance of agroindustrial production and exports from LDCs may be now more dependent than ever on the completion of reforms in the agricultural trade policies of DCs. For Africa, however, a more supportive international environment and better macroeconomic and trade policies will not be enough to ensure a thriving agroindustrial sector within a broader process of economic development until military confrontations stop.     

Emotional and satisfaction benefits to visitors as explanatory factors in the monetary valuation of environmental goods. An application to periurban green spaces

Over the last few decades, especially in urban areas, there has been a revival of the notion of quality of life in connection with periurban green spaces, the presence of which is thought to improve emotional well-being. This paper aims to determine how far the monetary valuation of this environmental resource is influenced by aspects relating to users’ emotional experience and satisfaction. The contingent valuation method is used to estimate monetary valuation and structural equation models allow examination of the relationships between visitor attitude and behaviour variables. The study focuses on two periurban green spaces in Spain and the data are obtained by means of face-to-face, in situ surveys of visitors. The findings support the relationship between visitor attitudes and the monetary valuation of this environmental good, revealing the need to advance further in exploring the potential of such natural resources to enhance urban social well-being.     

Semi‐Subsistence Farming: An Elusive Concept Posing Thorny Policy Questions

The massive expansion of semi‐subsistence farming in the European Union after the Eastern enlargements poses a real challenge to rural development. The problems of semi‐subsistence farms are low cash incomes and incidence of poverty, sub‐optimal use of land and labour, a lack of capital and poor contribution to rural growth. However, they play an important welfare function in some rural areas in Europe; they manage more than 11 million ha of agricultural land and deliver ecosystem services. The Common Agricultural Policy will have to accommodate this now widespread production system, through existing or new policy packages. Particularly important is support for commercialisation to incentivise and smooth the transition to commercial agriculture, and agri‐environmental payments to compensate the semi‐subsistence farmers for the provision of ecosystem services.     

Factors associated with landowner involvement in forest conservation programs in the U.S.: Implications for policy design and outreach

One-third of the forestland in the U.S. is owned by 10.4 million family forest owners. Their collective decisions have a great impact on the sustainability of forest landscape across the country. Public policies and programs for encouraging landowners to properly manage their land include cost-share, forest certification, and conservation easements. However, to date, less than 6% of the family forest owners have participated in a cost-share program, less than 1% have certified their land, and less than 2% have an easement. By analyzing data from USDA Forest Service's National Woodland Owner Survey, we examined the characteristics of family forest owners who had participated in these programs and identified strategies to capitalize on these landowner characteristics to improve current programs and attract a wider range of participants. We found that family forest owners with larger land holdings were more likely to participate in all three types of programs. Obtaining forest management information or advice was important for program participation; however, the effects differed depending on the types of programs and the sources of information. Income was not significant in predicting participation in cost-share programs, implying family forest owners from lower-income strata were not more likely to use cost-share program. The results also suggest the importance of targeting the right audience when promoting forest certification programs, namely those who are participants of cost-share programs, own forestland for reasons other than farming or ranching, and plan to harvest sawlogs or pulpwood in the future. Age was not significant in any of the empirical models. This result is particularly intriguing in the context of conservation easement, considering recent discussions about the high cost of dying unprepared and the potential for promoting conservation easement as part of estate planning among older family forest owners. Finally, few variables were significant in the model predicting landowner decision about donating or selling an easement, suggesting the easement decision is very different from cost-share and forest certification decisions and further efforts are needed to understand the dynamics of this increasingly popular conservation policy tool. In summary, this study provides a better understanding of the relationship between program participation and the demographics, attitudes and behaviors of family forest owners. This understanding contributes to the development of outreach strategies for improving landowner interest in forest conservation programs.     

Progress in indicators to assess agricultural landscape valuation: how and what is measured at different levels of governance

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.     

Technical,Allocative, Cost and Scale Efficiencies in Bangladesh Rice Cultivation: A Non‐parametric Approach

Applying programming techniques to detailed data for 406 rice farms in 21 villages, for 1997, produces inefficiency measures, which differ substantially from the results of simple yield and unit cost measures. For the Boro (dry) season, mean technical efficiency was 69.4 per cent, allocative efficiency was 81.3 per cent, cost efficiency was 56.2 per cent and scale efficiency 94.9 per cent. The Aman (wet) season results are similar, but a few points lower. Allocative inefficiency is due to overuse of labour, suggesting population pressure, and of fertiliser, where recommended rates may warrant revision. Second‐stage regressions show that large families are more inefficient, whereas farmers with better access to input markets, and those who do less off‐farm work, tend to be more efficient. The information on the sources of inter‐farm performance differentials could be used by the extension agents to help inefficient farmers. There is little excuse for such sub‐optimal use of survey data, which are often collected at substantial costs.     

Protest Responses and Willingness to Accept: Ecosystem Services Providers’ Preferences towards Incentive‐Based Schemes

The identification and treatment of protest responses in stated preference surveys has long been subject to debate. We analyse protest responses while investigating ecosystem services providers’ preferences for incentive‐based schemes. We use a choice experiment for olive farmers’ preferences for agri‐environmental scheme participation in southern Spain. Our two main objectives are: first, to identify and discuss a range of possible motives for protest responses that emerge in a WTA context; second, we analyse the impact on WTA estimates of censoring serial non‐participation linked to protest or high compensation requirements (very high takers). Using a random parameter logit model in WTA space, we find that the inclusion or exclusion of serial non‐participants in the analysis can have a significant impact on marginal and total WTA estimates. Based on the findings, the paper makes recommendations on how to reduce the incidence of protest responses through survey design, regarding the identification of protesters as opposed to very high takers, and regarding the treatment of both groups of respondents for WTA estimation.     

Comparing the environmental impacts of pasture-based and confinement-based dairy systems in Nova Scotia (Canada) using life cycle assessment

A life cycle assessment (LCA) of dairy systems in Nova Scotia was conducted to compare environmental impacts of typical pasture and confinement operations. Data on material and energy inputs and outputs of these systems were obtained from local researchers and industry, and life cycle impacts in 11 categories were quantified. Use of concentrate feeds, N fertilizers, transport fuels and electricity were dominant contributors to environmental impacts. Somewhat surprisingly, grazing cows for five months per year (typical of pasture systems in Nova Scotia) had little effect on overall environmental impact. Scenario modelling suggests, however, that prolonged grazing is potentially beneficial. Compared with total confinement, a seven-month grazing scenario performed better in seven of the environmental impact categories evaluated with greatest potential improvements associated with acidification potential, ozone depletion potential, human toxicity and fresh water ecotoxicity. In contrast, land use was the only category in which an increased reliance on pasture is predicted to result in a marked increase in environmental impact.
