The estimation of agricultural policy effects on soil erosion—An application for the bio-economic model MODAM

As agricultural policies affect land use, they have effects on the amount of soil erosion in agricultural regions through changes of the economic conditions of agricultural production. Prices of inputs and outputs, regulations and incentives can change, forcing or encouraging farmers to adopt new crop rotations. This paper shows how a bio-economic model can be used to describe and estimate the effects of policies on agricultural production and the risk of soil erosion at the example of a region in North-Eastern Germany. The model uses both an assessment tool that is based on a fuzzy-logic approach for the estimation of soil erosion risk of cropping practices, and a linear programming model, that simulates farmers’ economic behaviour under the assumption of gross margin maximisation being the main goal of farmers’ actions.The analysed policy options were both a targeted and an untargeted incentive programme for reduced tillage, and a restriction option where high erosive crops are not allowed on high erodible field types. The results show that policy changes can have an impact on soil erosion. Furthermore, soil conservation policies are shown to have different levels of efficiency in terms of reduced soil erosion related to the costs of the policy. In the case of this study, a restriction option was more efficient than the incentive options. The results of such simulations can serve as a decision support for the development of soil conservation policies and help to foresee the effects of general changes of agricultural policies.     

Revealing different understandings of soil held by scientists and farmers in the context of soil protection and management

This paper aims to analyse and draw together results from similar studies in England, Switzerland and France which investigated farmers’ understanding of soil and compared it with that of scientists, researchers and advisors (collectively called scientists in this analysis). A range of methods were used across the three studies and different theoretical approaches, looking at forms of knowledge, local practice of knowledge production and conceptions of reality, were employed to explain the results. Despite the different contexts, methodologies and theoretical approaches in the three studies, the results reveal similar patterns of difference in farmer and scientist understanding of soil. In the English study, farmers demonstrate a ‘know-how’ form or intuitive working knowledge of soil while advisors rely on scientifically established forms of ‘know-why’ and seek to understand and explain soil processes. Similarly in the Swiss study farmers’ and scientists’ differing perceptions are directed and shaped by their respective aims, methods and context of work. In the French study, farmers and researchers are shown to have different conceptions of soil, they attribute different meaning to the same activities, and use different words and language to describe the same features. In all three studies understanding is shown to be cultural and contextual, as such an integrative theoretical framework is proposed.     

Factors affecting farmers’ acceptance of conservation measures—A case study from north-eastern Germany

Intensive forms of agriculture have been proven to cause severe environmental effects, such as soil erosion by water and wind, or the pollution of ground and surface water with nutrients and pesticides contributing to the deterioration of natural habitats and the loss in biodiversity. In order to avoid or mitigate these detrimental environmental effects, a number of conservation measures can be undertaken by farmers. However, the adoption of these measures is highly dependent on the assumed benefits and risks attached as well as the personal perception and attitude of the individual farmer.This paper presents the outcome of a survey conducted in north-eastern Germany aimed at analysing farmers’ acceptance of different conservation measures. Eleven farmers, managing more than 80% (about 13,000 ha) of the agricultural land in the chosen case study region were interviewed. Respondents were asked about their personal experiences with different environmental measures and requested to assess these measures, e.g., regarding costs, time and labour demands, attached risks, or effectiveness. They also ranked these factors in terms of importance for decision making on adoption or rejection of a new measure. The findings show that, despite of the general assumption that farmers’ decisions are mostly driven by economic rationality, costs were not the most important factor. Other factors, like associated risks, effectiveness, or time and effort necessary to implement a certain measure were equally or even more important depending on the specific situation.     

Landscape properties as drivers for farm diversification: A Dutch case study

Farm diversification is stimulated by the societal demand to transform production countryside into consumption countryside. In most empirical studies on farmers’ decision making for diversification, geographical information is either omitted or reduced to a variable that links the farm to an administrative unit. Therefore, the influence of the exact farm location on farmers’ decision making is often lacking. The paper addresses the role of location, in terms of site specific natural conditions as well as neighboring dynamics, in influencing farmers’ decision making to diversify. Moreover, it investigates to what extend low returns from primary production stimulate farmers to find new survival strategies, and therefore explains diversification. The Gelderse Vallei area, a region in the center of the Netherlands, is used as a case study. For this area an extensive farm survey data could be combined with topographic data and soil maps (GIS). Both the number of activities as well as the kind of activities that are taken up are analyzed. Landscape attractiveness turns out to be a driver of diversification. Daily recreation most frequently occurs close to national parks, green services are more likely to occur on relatively wet soils. Activities resulting from diversification might produce positive externalities: new activities have the tendency to emerge next to already existing ones, therewith explaining the formation of “hotspots” in the landscape. Finally, diversification was found to be sensitive to returns from primary agriculture production.     

Implications of CAP reform for land management and runoff control in England and Wales

WTO negotiations, as well as problems associated with intensive agriculture, such as overproduction, dependency on high levels of subsidies, diffuse pollution, soil degradation and loss of wildlife, have led to a reconsideration of agricultural policies in Europe. In April 2005, the new common agricultural policy (CAP)-reform came into force in the United Kingdom, decoupling financial support to farmers from agricultural production. Farm income support payments are now linked to compliance with standards (cross-compliance rules) which protect the environment, animal health and welfare. In the light of these policy changes, semi-structured interviews were carried out with 36 farmers in five catchments in the UK to explore interrelationships between CAP-reform, agricultural land management and runoff-related problems. Results from three catchments are specifically highlighted because of their relevance for soil policy.The CAP-reform appears to facilitate and accelerate changes in the agricultural sector that were already happening. It is likely that upland livestock farms will extensify further, which will reduce environmental burdens such as diffuse pollution, soil compaction and runoff. The uptake of agri-environment schemes by individual farmers has increased since the CAP-reform. However, additional impacts are limited as there is a tendency among participants to enter these schemes based on existing features and practices.Although most farmers interviewed for this study appear to recognise the need to reduce soil erosion and diffuse pollution, they are less convinced they should be held responsible for controlling storm-water runoff from farmland that might contribute to flooding downstream. However, there are opportunities to achieve several objectives simultaneously, including improved soil management, runoff control and reduced pollution. Lessons can be learned from farmers’ opinions about CAP-reform, from successful interventions that aimed to reduce soil erosion and diffuse pollution, and also from failures. Recommendations are made for improvements to the current agri-environment schemes and to promote land management practices with less environmental burden.     

Determinants of the Willingness of Belgian Farmers to Participate in Agri‐environmental Measures

This paper explores the willingness of Belgian farmers to participate in two voluntary agri‐environmental policies. Farmers' contingent behaviour is analysed on the basis of survey data. Derivations based on a conceptual micro‐economic model indicate that decision subject and decision maker characteristics are important for farmers' participation. The model is empirically tested through the specification and estimation of a probit model. Consistency is found between the theoretical framework and the empirical results indicating that both the expected effect on farm production and the farmers' environmental attitude, which is more positive among younger and better educated farmers, are significant determinants of the acceptance rate of agri‐environmental policies. Other variables which influence participation decisions are farm size and previous experience of farmers themselves or of neighbouring farmers with agri‐environmental measures.     

Adoption of conservation agriculture in Europe: Lessons of the KASSA project

According to KASSA findings, conservation agriculture is less adopted in Europe compared to other adopting regions and, reduced tillage is more common than no-tillage and cover crops. Currently, it is not popularised and it is less researched. The lack of knowledge on conservation agriculture systems and their management and, the absence of dynamic and effective innovation systems make it difficult and socio-economically risky for European farmers to give up ploughing which is a paradigm rooted in their cultural backgrounds. In Norway and Germany the adoption of conservation agriculture has been encouraged and subsidised in order to mitigate soil erosion. In the other European countries the adoption process seems mainly driven by farmers and, the major driving force has been the cost reduction in machinery, fuel and labour saving. Soil and water conservation concerns did not appear as main drivers in the European farmers’ decision to shift or not to conservation agriculture.The shift of European farmers to conservation agriculture is being achieved through a step-by-step attitude, large scale farms are the most adopters. This adoption trend may grow in the future. Indeed, the need to improve farms’ competitiveness, the market globalization and the steady increase of fuel cost will likely contribute to arouse European farmers’ interest in conservation agriculture as it slashes significantly the production costs.Conservation agriculture is not equally suitable for all the European agroecosystems. The need of soil and water conservation in Europe requires anticipating the ongoing process in order to improve its ecological and socio-economic sustainability. Priority would be to define which regions in Europe are the most suitable for conservation agriculture taking into account climate and soil constraints, length of growing period, water availability and quality, erosion hazards and farming conditions. Policy favouring the use of soil cover and profitable crop rotations as management strategies for weed, pest and diseases control will certainly allow developing and disseminating efficient and acceptable conservation agriculture systems.     

Environmental farm planning in Ontario: exploring participation and the endurance of change

The Ontario Environmental Farm Plan Programme (EFP) represents a significant departure from previous agri-environmental initiatives in Canada. In this programme, the focus is not on the promotion and adoption of any particular farming innovation, but rather on the completion of a farm-level environmental appraisal and the development of a farm-specific environmental action plan. As with more traditional schemes, there is interest in understanding how the programme is performing and in documenting outcomes. Evidence suggests that a significant proportion of farmers who enter the programme complete only part of the process or apply the evaluation to only certain aspects of their operation. In effect, there is variation in the way participants participate. This paper examines the nature of, and reasons for, differing levels of engagement among participants in the EFP Programme. Results from a survey of past participants suggests that farm-specific environmental conditions, farmers’ motivations concerning the environment, and positive perceptions of the programme itself are associated with more complete levels of participation. Underlying some of the revealed variations in participation are abiding concerns for the confidentiality of the process and more general concerns relating to the intervention of the state in agricultural land use.     

Commonage land and farmer uptake of the rural environment protection scheme in Ireland

This paper looks at some of the factors which may influence REPS participation among commonage farmers in the west of The Republic of Ireland and on the impact REPS has had on participating farmers’ income and on their environmental practices and attitudes. Commonage is land held in common ownership on which two or more farmers have grazing rights. There are about 4500 commonages in Ireland and they are important to Irish agriculture, to conservation of the uplands, in managing the environment and in sustaining rural livelihoods. The study reveals that sheep farmers are less likely to join REPS than cattle farmers and that being in receipt of other sources of State income acted as a deterrent to participation. REPS appears to have had a positive impact on participants’ income and seems to have been successful in changing farmer practices in a more environmentally benign direction, when doing so imposed no additional costs on the farmer. Environmental awareness among all farmers appears to be poor although REPS farmers display more appreciation of the degraded state of commonage than do non-REPS farmers. Farmers preference for a continuation of the status quo with respect to commonage management and a lack of discontent with respect to the distribution of past commonage rights points to the potential of building on a more co-operative approach to environmental management.     

Farmers’ intrinsic motivations,barriers to the adoption of conservation practices and effectiveness of policy instruments: Empirical evidence from northern Australia

The rate and extent of adoption of conservation practices by farmers is influenced, in principle, by characteristics of the practices and those of the farmers. Governments use policy instruments to increase the rate of adoption of practices which generate public benefits if it is deemed that privately optimal adoption rates will not lead to publicly optimal conservation outcomes. Recent nation-wide conservation programs in Australia have attracted criticism for low levels of effectiveness and efficiency. Could it be that program design has ignored key adoption factors, in particular characteristics of the target audience? If adoption is subject to personal factors, such as the motivations for farming, then it is likely that so are farmers’ responses to policy approaches and instruments. In this case study, surveys were conducted of farmers in three regions within the tropical savannas of northern Australia, where land-use systems are characterized by large-scale broad-acre beef grazing enterprises. Inter alia, these surveys collected data on graziers’ motivations, impediments to adoption of conservation practices, and perceived effectiveness of policy instruments in overcoming impediments. The research found that graziers had a very high level of conservation and lifestyle motivation and were motivated to lesser extents by financial/economic and social considerations, pointing to a strong stewardship ethic of graziers, or altruistic motif. Motivational profiles were significantly correlated with farmers’ perceptions about what constrained them from implementing conservation based management systems. Motivational profiles also explained differences in farmers’ perceptions of and stated propensity to interact with policy instruments, particularly at a regional scale and in the context of historical government interventions. On the basis of the empirical evidence presented, governments would be well advised to harness the diverse set of aspirations and motivations of farmers when designing conservation programs rather than. In particular, conservation programs need to take advantage of farmers’ stewardship ethic for maximum effectiveness and efficiency, and minimize the risk of crowding out intrinsic motivation and altruistic behaviours.     

The ‘Neighbourhood Effect’: A multidisciplinary assessment of the case for farmer co-ordination in agri-environmental programmes

In this paper we present a multi-disciplinary analysis of the potential impacts of undertaking similar environmental actions on multiple farms in a small geographic area, using organic farming as a proxy for a co-ordinated approach. Recent papers have called for more co-ordinated efforts between farmers in terms of their environmental actions, but there has been limited applied research demonstrating the environmental benefits or the economic and social implications to farmers of this approach. Comparative analysis of biodiversity, soil and water, and farm profitability were undertaken in England on 32 matched farms in areas of low and high organic farming concentration; qualitative interviews were also conducted with 48 farmers living in two of the eight areas. Findings demonstrate higher overall levels of biodiversity on organic farms (particularly in “hotspot” areas) but this was not universal across the species groups investigated. Higher water infiltration rates were found in organic grasslands, which could prove to be a useful measure to combat flooding. In terms of the technical efficiency of producing these environmental gains, conventional and organic farms in hotspot areas demonstrated equivalent efficiency from a financial perspective. Socio-cultural research identified the different amounts of trust farmers have in their neighbours, based in part on their performance as ‘good farmers’. We discuss the neighbourhood effect with a multi-disciplinary approach and conclude that encouraging local farmer co-ordination can have clear environmental benefits without high economic cost, but must be undertaken with caution - specifically regarding the trade-offs between benefits, local geophysical and social characteristics, and assumptions made about inter-farmer trust.     

State corporatism and environmental harm: Tax farming and desertification in northwestern China

Research on environmental governance in China has shown that centre–local relations often influence the implementation and efficacy of environmental regulations. By examining changes in resource allocation and rural development between 1982 and 2005 in the region worst affected by desertification in China—the Minqin oasis in Gansu—we argue that changes in macro‐level fiscal and commodity grain policies contributed to severe regional disparity and a reduction in local state capacity in hinterland China. Intergovernmental competition over fiscal revenue encouraged cash cropping and land reclamation, and the continuous decline of the oasis ecology further reduced legitimacy in rural governance. These institutional and ecological constraints shaped the behaviour of grassroots cadres and formed the conflicting interests of the state in resource distribution and environmental conservation that continued to exist until the implementation of a centralized conservation program in 2006. The data came from 157 interviews and 628 policy documents from local archives in Gansu.     

Farmer participation in agri-environmental schemes: Regionalisation and the role of bridging social capital

European agri-environmental schemes are being criticised for reinforcing rather than negating an opposition between agricultural production and environmental production, and for assuming instead of securing a public willingness to pay for agri-environmental change. This paper explores if a regionalisation of agri-environmental governance may contribute to overcome these criticisms. The paper empirically explores three regionalised agri-environmental schemes from Flanders, Belgium, with the use of 40 qualitative interviews with farmers and other relevant stakeholders. Building on the Bourdieusian theory of capital and the conceptual distinction between bonding and bridging social capital, the paper analyses whether and why the regionalised arrangements incited farmers to integrate environmental production in their farm management to meet other regional stakeholders’ demands for agri-environmental change. In doing so, the paper particularly focuses on the role of bridging social capital in fostering farmer participation in agri-environmental governance, which is a topic that—despite a growing scholarly recognition of the importance of social capital in mediating farmers’ environmental behaviour—has to date received scant conceptual and empirical attention. The paper reveals that farmers principally participated in the regionalised agri-environmental schemes to enhance the long-term viability of their agricultural businesses by building up more cooperative and appreciative, bridging social ties with other regional stakeholders. Notably, such participation is only likely to be substantive and lead to long-term, pro-environmental behaviour change of farmers, if farmers actually succeed in building up bridging social capital by receiving other regional stakeholders’ appreciation for their agri-environmental work. The paper ends with discussing the implications of these findings for the future design and implementation of socially and ecologically robust agri-environmental schemes.     

An integrated approach for ex-ante evaluation of public policies for sustainable agriculture at landscape level

An integrated methodological framework for ex-ante evaluation and planning of public policies for sustainable agriculture at agro-landscape level is proposed. The components of the framework are to: (1) determine the private, i.e. farmers’, and public benefits associated to agro-landscapes, consisting of an agricultural land-use system, according to its performance for several market and non-market functions. Market forces determine the market benefits and preferences of society the non-market benefits; (2) explore and select potential sustainable agro-landscapes based on the private and public benefits associated with possible land-use alternatives; (3) define efficient public policy mechanisms for improving social net benefit of agro-landscapes.The framework is illustrated with a case study in a small dairy farming dominated agro-landscape in The Netherlands, with gross margin, landscape quality, nature value and environmental health as the analysed ecosystem functions. Alternative landscapes consisting of hedgerow configurations and grassland management practices were explored, yielding a set of alternatives representing the solution space in terms of change in private and public benefits. Policy mechanisms were defined to move from the current to a desired landscape based on changes in social net benefits. Moreover, the necessity of a modification in the current agri-environmental support was analysed for each landscape. The analysis considered all farmers in the agro-landscape jointly. The results for the case study showed potential prototypes of landscapes and their performance compared to the current landscape. Extension was the most efficient policy mechanism to promote the change to the socially optimum landscape alternative.

Conflicts in land use in Zimbabwe: Political, economic and environmental perspectives

Major conflicts have developed between and within the two main farming systems in Zimbabwe, especially over the past thirty or so years. Since independence in 1980 policies have favoured expropriation of land from commercial farms to resettle peasant farmers as a means of relieving ‘land hunger’ in the peasant sector. This article argues that that is a very simplistic view of current land-use problems, and that resettlement programmes are only a partial solution to the immense problems within the peasant sector. These are the product of a complex history of development incorporating political, economic and environmental issues. The article outlines the main features of this development so that a more balanced perspective on current problems can be achieved and so that more appropriate strategies to tackle the problems can be devised.     

重点生态区位商品林生态补偿利益相关者演化博弈研究

根据演化博弈理论,构建动态演化博弈模型,探讨重点生态区位商品林生态补偿过程中各利益主体在有限理性条件下的利益驱动、决策行为和依据以及主体间交互作用下的演化稳定策略,分析在不同情境下影响林农和地方政府演化博弈均衡的因素。研究结果表明:两大博弈主体的策略选择和策略演化方向依赖于初始状态及其演化路径,并与博弈矩阵的参数有关;地方政府的行为决策直接影响生态补偿项目的可持续性;作为项目的直接实施主体,林农的积极性与响应度直接影响生态补偿项目的实施效果。因此,应该建立健全生态补偿,完善生态环境保护激励机制,构建政府主导、林农参与的环境保护工作机制。

Modeling farm households for estimating the efficiency of policy instruments on sustainable land use in Haiti

Degradation of natural resources in Haiti has been a growing concern to foresters, environmentalists, and local populations. Various approaches based on “participatory”, “fines and taxes” and “command and control” regulations, have been unsuccessfully implemented to persuade farm households to adopt conservation measures. Negative impacts on the welfare of farmers limit the efficiency of these approaches for forest conservation. This paper investigates alternative solutions to the problem of deforestation of Haiti using linear programming (LP) models. More specifically, this study evaluates the role of various policy instruments on large-income farm households and low-income farm households’ welfare and forest conservation in Haiti. Data from 243 farmers inside the Forêt of the Forêt des Pins Reserve are used in the empirical analysis. Results suggest that agricultural subsidies tied to environmental conservation would promote a more sustainable resource use in Forêt des Pins Reserve.
