Multifunctionality of agriculture: an inquiry into the complementarity between landscape preservation and food security

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

Is Passive Farming A Problem for Agriculture in the EU?

We address a new agricultural policy concern following the decoupling of CAP direct payments in 2005: passive farming, whereby landowners maintain their agricultural area to collect payments without producing commodities. It is claimed that passive farming is hindering agricultural development by ‘blocking’ access to farmland for expanding farmers. We evaluate the links between the EU's Single Payment Scheme (SPS), passive farming, land use and agricultural development. Following identification of the rational landowners’ optimal land‐use choice, we evaluate the effects of the SPS using a spatial, agent‐based model that simulates farmers’ competition for land in a case‐study region of Sweden. We show that passive farming does not constrain land from being used in production; on the contrary more land is used than would be the case without the SPS. We conclude that passive farming is not a problem for agriculture, but provides public goods that would otherwise be under provided: preservation of marginal farmland and future food security. However SPS payments on highly productive land inflate land values (capitalisation) and slow structural change, which hinder agricultural development. Consequently CAP goals could be better served by targeting payments on marginal land and phasing out payments to highly productive land.

Land-property markets and planning: A special case

Land use policy often intervenes in land-property markets. This raises a question that may have critical implications for land use policy: are these normal markets? This paper addresses that question: are land and property ordinary market goods, or do they lack some of the preconditions necessary for markets to work properly? We find that land-property has limited substitutability, due to the critical factor of location; qualified by location, land is limited and sometimes unique. These attributes make land and property investment assets risking speculation, warranting public intervention to mitigate negative social consequences. Land-property markets need market or administrative support to work, which planning provides through public and private agents. The paper reviews the different forms of planning and development control in land-property markets.     

Interaction effects of targeted agri-environmental payments on non-marketed goods and services under climate change in a mountain region

Targeting of agri-environmental measures (AEMs) is a key to increasing the cost-effectiveness of governmental support for biodiversity conservation and the provision of ecosystem services from agriculture. Existing literature, however, often focuses on single measures without considering that policies are usually bundles of different measures addressing multiple non-marketed goods and services. Thus, interaction effects of a set of policies in a given policy mix may influence the cost-effectiveness of single measures. Recently, Swiss agricultural policy was redesigned using the Tinbergen rule as its basis, i.e., a single measure for each policy goal, including additional targeted direct payments. This facilitates testing for interaction effects of multiple targeted AEMs. Here we use a social-ecological, agent-based modelling framework to assess interaction effects of these agricultural policies while accounting for climate change impacts in our analysis. The results from our case study in a mountain region show that ecosystem service provision increases with targeted payments. However, interaction effects of the different targeted policies affect the provision levels of all goods and services. In particular, changes at the extensive margin, i.e., the total amount of land that is under production, largely determine the amount of ecosystem services provided. Thus, climate change driven productivity increases and policies that keep land in production may substantially support the provision of non-marketed goods and services in marginal agricultural production regions with a high potential for land abandonment. Consequently, the effectiveness of targeted policy measures should also consider changes at the extensive margin and be assessed in the context of bundles or portfolios of different policy measures.     

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.

Agricultural Extension Policy in Australia: Public Funding And Market Failure

Trends in public expenditure on agricultural extension are examined for Agriculture Departments in four States. There is little evidence that the share of public resources going to extension has declined. However, new demands have meant that the nature of extension has changed. A strategic approach to examining issues, such as land degradation, for the source of market failure may better guide the use of scarce public resources than the traditional focus on the public goods characteristics of research and extension. The case for evaluating broad functions such as research and extension is becoming more questionable as these functions become more diverse.     

Disadvantage and economic viability: characterising vulnerabilities and resilience in upland farming systems

Less Favoured Areas (LFA) were designated to support farming activity on land with limited productive potential. However, progressive land abandonment in these areas questions the rationale and targeting of support payments to maintain viable farming enterprises. Using micro level data on farm businesses over the period 2003-2016 matched to land capability and spatial data we identify the distribution of viable and vulnerable enterprises in Less Favoured Areas. We find five categories of household based on progressive quality of life thresholds, namely i. vulnerable, ii. sustainable, iii. viable, iv. resilient, and v. robust. A proportional odds model measured the effect of biophysical and remote disadvantage on predicting these states of viability, along with farm family lifecycle factors. Whilst we would expect higher proportions of disadvantaged farmland to be negatively related to viability, when combined with rural remoteness this increases the magnitude of the effect. However, clear succession planning and tenancy arrangements suggest that approaches to management of the business and the farm family life-cycle may overcome some of these disadvantages. These results have to be considered against the UK’s planned withdrawal from the Common Agricultural Policy. This offers opportunities to provide a more nuanced approach to targeting and supporting disadvantaged regions beyond current criteria. However, there would seem to be dissonance between the proposed payment for public goods agenda, which is results orientated, and support for correcting natural disadvantages where opportunities for delivery of these public goods will be limited.     

Factors affecting farm growth intentions of family farms in mountain regions: Empirical evidence for Central Switzerland

Family farms in mountain regions are undergoing a progressive structural change and an ongoing shift in the allocation of production factors land, capital and labor. In Switzerland, various policy measures influence the re-allocation of these production factors. To understand the effectiveness of these schemes and to assess future farm structural change, it is useful to analyze the underlying drivers which support and hinder the emergence of individual farm growth strategies. We study the family farms’ growth intentions using a logistic regression model based on a combination of census and survey data on family characteristics from two mountain case study regions in Central Switzerland. Factors supporting farm growth intentions are the relative change in farm size in recent years, farm related sunk costs, farm diversification and farm size. We found no support for the hypothesis that farm growth intention is also influenced by the perceived personal situation represented by indicators for the perceived workload, psychological stress and financial problems. In addition, off-farm labor did not prevent farmers from stating growth intentions. Our empirical findings suggest that (i) the most important factors which support farm growth intentions correspond with factors driving observed patterns of structural change; (ii) limited availability of family labor may result in a new critical threshold for farm growth strategies; (iii) aims and non-pecuniary preferences of farmers will impede a rapid structural change in the near future.     

The Governance of Rural Land in a Liberalised World

Liberalisation of agricultural policies reduces the influence of policy on land‐use decisions, but environmental policy objectives remain. Governance provides an approach that recognises the role of institutions and collective action. The formulation of environmental policy objectives in terms of the provision of public goods raises questions as to the role of economic valuation and as to whether the definition of ‘goods’ may misdirect policy attention. An alternative approach relates to ecosystem services and sees management issues in terms of ecosystem resilience and the adaptive governance of socio‐ecological systems. Governance involves a mix of regulation, markets, government incentives and collective action. Regulation sets the domain within which markets operate and social judgements as to property rights are required as a basis for exchanges. Depending on commodity prices, agri‐environment schemes may be required either to reduce agricultural production intensity or to keep land under production. The diffuse nature of the environmental benefits and costs of land uses, the complexity of ecosystems and the need to co‐ordinate land management decisions indicate a role for local adaptive co‐management of land resources. Governments play a major role in supporting the institutional framework within which this can take place.     

Horse riding posing challenges to the Swedish Right of Public Access

Increasing numbers of horses are being kept for sports and leisure purposes in peri-urban areas throughout the Western world. This expansion of the equestrian sector represents a multifunctional transition, with new production of rural goods and services and increasing influence on land use.In Sweden, the number of horses has increased from 70,000 to approximately 300,000 over the last 30 years. This increase is putting pressure on the traditional Right of Public Access, an old custom allowing the public to walk, cycle or ride on private or state-owned property.This paper analyses multifunctional land use in peri-urban areas in order to provide a deeper understanding of the potential conflicts arising due to the expanding equine sector and to assess how these can affect the Swedish right of public access and spatial planning.A survey of horse riders and landowners in three peri-urban regions of Sweden revealed that these groups differ in their attitudes towards the Right of Public Access. The data also showed that the expanding equine sector is generating new demands on rural areas and there are questions regarding how the current system of open accessibility can meet the increasing market for equestrian leisure activities. The main conclusion is that there seems to be a strong need for intervention and deliberate creation of new ways of handling the accessibility question, where both a bottom-up and top-down approach may be useful.

Adverse Selection in the Environmental Stewardship Scheme: Does the Higher Level Stewardship Scheme Design Reduce Adverse Selection?

The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on foregone agricultural income. This creates a potential incentive compatibility problem which, combined with information asymmetry about farm land potential, can lead to adverse selection of land into the Scheme and therefore a less cost‐effective provision of environmental goods and services. However, the Higher Level Stewardship (HLS) Scheme design includes some features that potentially reduce adverse selection. This paper studies the adverse selection problem of the HLS using a principal‐agent framework at the regional level. It is found that, at the regional level, the enrolment of more land from lower payment regions for a given budget constraint has reduced the adverse selection problem through contracting a greater overall area and thus higher overall environmental benefit. In addition, for landscape regions with the same payment rate (i.e. of the same agricultural value), differential weighting of the public demand for environmental goods and services provided by agriculture (measured by weighting an environmental benefit function by the distance to main cities) appears to be reflected in the regulator’s allocation of contracts, thereby also reducing the adverse selection problem.     

Analysis of individual private forestry in northern Spain according to economic factors related to management

In addition to being motivated by profit, the management decisions taken by non-industrial private forest (NIPF) owners involve other considerations beyond timber, such as non-timber goods and services, as well as factors that affect the level of timber output from the land. Ensuring and improving forest profitability to make NIPF management viable is one of the main challenges faced by this type of landowner. This study empirically explores and assesses management by NIPF owners, through analysing attributes of forest economics (investment in holdings, expenditure on planting and silviculture, public subsidies, along with timber and non-timber incomes). With the aim of predicting outcomes, a multiple regression model was also constructed to investigate and quantify the relationship between socioeconomic and holding factors, and the planting activities carried out by NIPF owners. For this, 103 resident forest landowners in a forest region in northern Spain were interviewed in person, during March 2004, about their commitment to and involvement in land management during the period 1999–2003. The results mainly revealed that attractive forest returns and favourable market conditions for timber production are significant factors for investment in and development of forestry, with personal and family conditions also being important factors in explaining the type of land management carried out. In particular, the multiple linear regression model for forest planting activity correctly explained 84.5% of the variability observed in the study population, indicating that both the investments in and the incomes from forestry play an important role in the activity, as does the size of the holding. The findings may be of interest in promoting public measures related to timber markets and economic incentives for forest management, which will allow landowners to develop economically viable practices, as well as enabling fulfilment of social and environmental demands for sustainable forestry and rural development.     

Property rights of urban underground space in China: A public good perspective

With the booming development of urban underground space in China, “fuzzy” property rights of this special form of land use type are not only the cause of ownership disputation and registration chaos, but also may seriously delay the undertaking of related underground land laws or regulations. China's emerging property rights issue of urban underground space, especially the delimitation of the surface and ground or underground, is facing such a challenge. This article aims to identify the property rights of urban underground space by using a practical method that classifies the underground space as economic goods, and to analyze attributes of different property rights of urban underground space within the theoretical framework of public goods. We use civil defense projects and underground parking lots as case studies. Both case studies are the most utilized types and controversial ownership cases of urban underground space in present China. Our case studies indicate that it is a feasible method to avoid the delimitation of the start-stop height of 3D property right vertically, and directly define the attributes of surface and underground property rights in line with the supply mode of goods. Our results show that the method proposed in this study can effectively solve the dispute of property rights against problems rising with unclear contract and lags in the legislation of urban underground space and clearly delimited the interests boundaries among different parties of property rights for urban underground space. Ultimately, this study may offer better insight into the utilization and registration work of urban underground space in China as well as reference for countries with similar property rights issues.     

Soil is brown gold in the Emilia-Romagna region,Italy

Soil is a natural resource essential to human welfare by virtue of its numerous crucial functions. In the past, soil has been taken for granted because of its widespread, albeit finite, availability. However, now that world's population is projected to exceed ten billion before the end of this century, soil is increasingly perceived as a precious commodity. Consequently, soil is increasingly under pressure by rich private investors and governments within the poorest countries to satisfy appetites for food production and biofuel. A case study is used to explore the plausibility of soil being considered as ‘brown gold’. Based on the comparison of land use maps, we estimated the value in terms of resource from raw material, carbon sink and virtual calories of the productive soil lost during the period 2003–2008 in the Emilia-Romagna Plain, one of the most productive areas of Italy. More than fifteen thousand hectares of cropland underwent land use change – in particular urbanization – over the 6-year period with an implied loss of crop production potential equivalent to the daily calorific requirement of more than 440,000 people. Taking into account that Italy is no longer self-sufficient in food production, such a loss appears to be strategically significant. Perhaps more importantly, urbanization and soil sealing has had negative ramifications on environmental sustainability, on both local and broad scales, with increased consumption of public funds. A logical framework of the socio-economic impact of land use change has been compiled and is presented as a possible example of a policy relevant approach to managing productive soils as a finite resource.     

Past and future impacts of land use and climate change on agricultural ecosystem services in the Czech Republic

Climatic and land use change are amongst the greatest global environmental pressures resulting from anthropogenic activities. Both significantly influence the provision of crucial ecosystem services, such as carbon sequestration, water flow regulation, and food and fibre production, at a variety of scales. The aim of this study is to provide spatially explicit information at a national level on climate and land use change impacts in order to assess changes in the provision of ecosystem services. This work provides a qualitative and quantitative analysis of the impacts on selected ecosystem services (carbon sequestration, food production and soil erosion) in the agricultural sector of the Czech Republic. This assessment shows that, historical land use trends and land use under projected climate scenarios display some shared spatial patterns. Specifically, these factors both lead to a significant decrease of arable land in the border fringes of the Czech Republic, which is to some extent replaced by grasslands, in turn affecting the provision of ecosystem services. Moreover, this assessment contributes to a useful method for integrating spatially explicit land use and climate change analysis that can be applied to other sectors or transition countries elsewhere.     

Key socio-economic factors influencing sustainable land management investments in the West Usambara Highlands,Tanzania

Low investments in sustainable land management (SLM) limit agricultural production in the East African Highlands, leading to increased soil erosion, low productivity of land and food insecurity. Recent studies in the region show that different socio-economic factors influence SLM investments by farmers, but knowledge on which of these are most influential and how to foster SLM is often lacking. This research fills this gap for the West Usambara Highlands, and determines key socio-economic factors influencing investments in SLM. Data for this research was collected from 196 randomly selected farm households in the Lushoto district, and Factor Analysis was used to reveal patterns of correlation between SLM investments and different household characteristics. Among the eight socioeconomic factors generated by Factor Analysis, four key factors were found to significantly influence SLM investments in upland (mainly rain-fed) agricultural fields: (1) the farmer’s access to support services; (2) the farmer’s experience with collaborative land management; (3) the household’s income from crop sales; and (4) the farmer’s forward driven attitude. The study concludes that a strategy to foster and scale-up SLM in the West Usambara Highlands should therefore improve the access of farmers to support services (especially micro-credits), trigger collaborative efforts in land management (e.g., farmer-to-farmer training) and promote investments in the rural area to create an enabling environment for SLM. A more active role of the Government, together with public and private sector partners, is therefore crucial.
