The role of behavioural factors and opportunity costs in farmers' participation in voluntary agri-environmental schemes: A systematic review

Agri-environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and having positive attitudes towards AESs. Moreover, several factors related to opportunity costs also have a rather consistent relationship with AES participation, including market conditions, implementation efforts, profitability, and management and contract flexibility. However, many relationships of behavioural factors and opportunity costs with AES participation are not as consistent and generalizable as sometimes portrayed and require context-specific interpretation. Those factors with mixed results can still provide insights into farmers' participation decisions as several of them are either ‘positively and insignificantly’ or ‘negatively and insignificantly’ related to participation, such as environmental attitude, trust and farm size. These results suggest that their relationship with AES participation depends on other factors or the setting, highlighting interactions and raising important new research questions. Overall, our results provide several entry points for both researchers and policy-makers, highlighting uncertainties in relationships between factors and participation that should be considered when designing policies.     

Farmer perspectives of the on-farm and off-farm pros and cons of planted multifunctional riparian margins

The planting of riparian margins is a policy option for pastoral farmers in response to land use induced environmental issues such as declining water quality, stream bank erosion, and loss of aquatic and terrestrial habitat. We elicited the views and experiences as to pros and cons of planting riparian margins from two sets of dairy farmers from Taranaki, New Zealand: those who are or have planted riparian margins, and those who have not yet done so. Those farmers who have planted riparian margins identified 21 positive aspects of riparian margin plantings and 11 negative aspects of riparian margin plantings. Perceived benefits identified by this group include water quality, increased biodiversity, the provision of cultural ecosystem services, immediate direct benefits to farm management and the farm system, and in some instances increased productivity on-farm. In contrast, those farmers that had fenced but not planted their riparian margins did not consider that riparian margin plantings could add further benefits to that which could be achieved by excluding stock from waterways, and associated only negative perceptions with riparian margin plantings. Planting riparian margins is not cost neutral and will not deliver anticipated environmental benefits in every situation. However, we argue that riparian margin plantings are an important ecological infrastructure investment that needs to be captured within a wider policy framework, the benefits of which extend beyond the mitigation of a single negative externality generated by land use practices, such as nutrient loss, and contribute to a multifunctional landscape.     

Group heterogeneity and the economic effect of farmer organisation participation: Empirical evidence from Taiwan

We explore the effects of different farmer organisations on smallholder farmers' economic performance. The average treatment effect of switching between different farmer organisations is examined. In addition, based on the premise that a higher level of social capital is accumulated through participation in multiple farmer organisations, we also investigate how the economic consequences of farmer organisation membership vary with the intensity of participation. Our conceptual model explicitly includes social capital to provide a micro-foundation and a theoretical justification for the linkage between farmer organisation participation and the economic outcome. This indicates that participating in different types of farmer organisations is beneficial for farm households only when the returns from social capital investment outweigh the time cost of participation. Our empirical results suggest that membership of farmer organisations that are more homogeneous in terms of member specialty and similarity in production and marketing activities results in a significant increase in farm sales revenue and net returns. This result supports the view that technological proximity accentuates knowledge spillovers within the farmer organisations, and thus leads to better economic outcomes. In line with the prediction of the theoretical model, the average treatment effect of participation is found to increase with the number of organisations that farmers belong to. Moreover, results from the quantile regression provide empirical evidence supporting increasing returns to social capital accumulated through participation in several farmer organisations.

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.     

A social networks approach for strengthening participation in technology innovation: lessons learnt from the Mount Elgon region of Kenya and Uganda

Participatory approaches to agricultural technology development have not yet fully lived up to their promise to incorporate farmer knowledge. This paper introduces a social networks approach (SNA) to improve participatory research processes for co-innovation. Drawing upon findings from a collaborative project developing conservation agricultural production systems for smallholders in western Kenya and eastern Uganda, the paper explores farmer support networks to improve participation in technological innovation and development. Key research themes include: identifying farmers’ agricultural production networks; the local articulation of agricultural production networks and mindsets; using networks to facilitate meaningful participation in technology development; and disadvantages and advantages of using a social network approach. The introduction of SNA improved participatory research by building external and internal legitimacy for determining who participates, discouraging participatory attrition, and providing a meaningful forum for participation of all stakeholders. As a result, the introduction of SNA is demonstrated to show strong promise for improving processes of participatory technology development in agriculture.     

Sustainable crop production intensification in the Senegal and Niger River basins of francophone West Africa

This paper reports on how the farmer field school (FFS) approach has been used to successfully catalyse important changes among stakeholders in the savannah zones of West Africa. Improved agronomic practices, better decision-making skills and diversification of smallholder farms in developing countries are shown to provide farmers the opportunity to rebuild soil fertility, optimize input use and introduce new sources of food and nutrition and marketable products for local populations. This is a knowledge-intensive endeavour best addressed through community-based processes of education. By the end of 2010, approximately 116,000 rice, vegetable, cotton and other farmers would have been involved in season-long FFS in four West African countries, resulting in improved yields and incomes and ushering substantial progress in both reducing the use of chemical pesticides and improving the use of fertilizers and organic amendments. The programme is increasingly being successfully integrated into local, provincial and national structures. Experienced personnel are being employed to initiate similar programmes in nearby countries. The evolving network of experienced actors and committed countries provides a platform for collaboration by a growing set of partners and represents a large-scale, long-term programmatic approach to helping sustainably intensify and develop agriculture in Africa.     

Class and the Politics of Participatory Rural Transformation in West Bengal: An Alternative to World Bank Orthodoxy

Based on a primary field survey and secondary sources of information, this study analyzes the West Bengal experience of participatory rural transformation in relation to the changing class structure in a differentiated rural economy, the rise in class-consciousness among the rural poor and the participation of different classes in the political process of decision-making. Utsa Patnaik's (1987 ) labour exploitation criterion is used in order to rank rural households in class terms, alongside the standard acreage groupings. This study strongly refutes the neo-liberal (World Bank) idea of social capital and civil society as sources of 'people's participation'. It is argued that 'people's participation' is a meaningless concept, since the 'people' as a category includes different classes with conflicting interests. Though subordinate classes in West Bengal have achieved a higher level of class consciousness than in the past, and have resisted extra economic coercion, and while their political participation has risen, their involvement at the grass roots level of administrative decision-making is very weak. Panchayat Raj has so far failed to initiate a second phase of institutional reform in West Bengal, encompassing education, gender justice and above all the co-operative movement. This partial failure is the outcome of short-term electoral benefit being given priority over and so undermining class struggle.     

The complexity of exchange: Wheat markets,petty‐commodity producers and the emergence of commercial capital in colonial Punjab

This paper questions the orthodox Marxist view of merchant capital as “unproductive,” by highlighting the importance of traders in subsuming the countryside to the logic of capital. However, it also argues that in order to properly understand the role played by traders in agrarian change, critical Marxist scholarship on merchant capital needs to recognize the complex marketing systems in which traders and farmers operate. These markets have their own internal relations, organizational and institutional logic which in turn is tied to the specificity of the commodity. Using wheat markets in colonial Punjab as a case study, it then utilizes the framework of complex marketing systems to highlight the range of firms and farms that operated in these markets; the importance of personal relations and informal institutions of family, caste, and religion for establishing trust; and the class stratified nature of market participants. It was from within these informally organized markets that commercial capital first emerged in colonial Punjab. By creatively combining the concept of commercial capital with markets as complex systems, it hopes to provide a richer framework for the study of agrarian change in diverse contexts.     

Global investments in agricultural land and the role of the EU: Drivers,scope and potential impacts

This paper investigates the recent wave of investments in agricultural land, often referred to as land grabbing; a term that not only emphasises the appropriation of resources by investors but also implies a criticism of their potential impacts on livelihoods and ecosystems in the target countries. This phenomenon has increasingly been the focus of public attention as well as a source of concern for NGOs, international institutions, academia and civil society. More specifically, this study investigates the role that the European Union member states play, both collectively and individually, in this wave of acquisitions in agricultural land, by providing a comprehensive overview of the drivers, scope and potential impacts of these land deals.     

Harnessing sustainability,resilience and productivity through conservation agriculture: the case of likoti in Lesotho

Subsistence farmers in Lesotho have been able to boost agricultural yields and increase food production by adopting conservation agriculture. The practice, locally known as likoti, also contributes to combating soil erosion and to enhancing fertility. The socio-economic and environmental benefits help poor households to rehabilitate and strengthen their livelihood capital base and ultimately help rural communities to build system resilience in the face of widespread poverty and increasing vulnerability that affect the country. This paper discusses the major advantages associated with the spread of likoti. By drawing on primary data collected by FAO-Lesotho, it enquires into the determinants of adoption, thereby highlighting constraints and options for future up-scaling. The results show that attending appropriate training is a crucial prerequisite for the correct adoption of likoti. However, training is more effective when trainers pursue true participation and when social capital among farmers is stronger. Further important determinants of adoption are the level of education and the economic incentives provided to vulnerable households. Stronger policy and institutional support in all these areas would thus help address the cultural and resource constraints that limit the full potential of likoti to be harnessed and ultimately hinder its further spread throughout the country.     

Participatory trials and farmers' social realities: understanding the adoption of legume technologies in a Malawian farmer community

This article presents results from a study exploring the reasons for low adoption of legume technologies to improve soil fertility by farmers from a community in central Malawi who took part in participatory trials. This study explores the influence of gender roles in agriculture and land ownership and socio-economic differentiation in the community. Because most women do not own land and are traditionally responsible for legume crops, they have little interest in managing soil fertility for maize crops. Men are not interested in using legumes in maize-cropping systems. Some are too poor: this group needs to complement their subsistence maize production with paid labour on the farms of better-off farmers; restricting the labour availability for their own farming activities. Wealthier farmers have access to, and prefer to use chemical fertilizer and cattle manure. Take-up rates among the middle group of farmers were also low. This study discusses how these (and other) factors influence the (non-)adoption of maize-legume technologies in Malawi and the effectiveness of participatory research. It emphasizes how differentiated farmer-realities affect the uptake of technologies identified as promising in participatory field evaluations.

Enhancing food security in South Sudan: the role of markets and regional trade

South Sudan faces serious problems of food insecurity due to low levels of domestic food production, periodic droughts, widespread poverty, and since late 2013, renewed armed conflict. This article explores market price behavior using cointegration analysis and estimates the effects of production and trade shocks through multimarket model simulations. We show that market prices in the capital city, Juba, of both maize and sorghum are cointegrated with import parity prices of these cereals sourced from Uganda, consistent with observed trade flows. Model simulations, using econometrically estimated demand parameters, suggest that private sector imports of maize and wheat would greatly mitigate the potential fall in consumption in the case of a decline in domestic cereal production. Other simulations indicate that if total imports of cereals are reduced by one‐third (still more than two times the levels of food aid in 2013) because of disruptions to private market flows, domestic prices of cereals could rise by 45% or more. The article concludes that whatever measures are taken involving national food security reserves, it is crucial that government policy serves to maintain incentives for private sector imports to avoid destabilizing market supplies, domestic prices, and ultimately, food consumption of the poor.
