How farmers benefit from plant clinics: an impact study in Bolivia

Between 2000 and 2009, nine plant clinics in three agro-ecological areas of Bolivia (Andes, lowlands and valleys) served about 800 communities in an area roughly 300 × 100km. Over 6000 farmers consulted these clinics with 9000 queries. Many found the advice so useful that they visited the clinics repeatedly. A survey of 238 clinic users found that most adopted the clinics' recommendations. Fruit and vegetable growers who followed the clinic recommendations tended to spend less on pesticides. As for certain crops like potato, citrus and peach palm, a modest increase in pesticides helped improve the quality and quantity of the harvest. Farmers improved their incomes by following the clinics' advice. The poorest farmers enjoyed the greatest increase in income per hectare. This was the first study to explore the impact of plant clinics; future studies need to be improved, for example by obtaining baseline data and by comparing clinic users to their peers who have not used clinics.     

Do Plant Clinics Improve Household Food Security? Evidence from Rwanda

One of the main drivers of food insecurity is pests, which are estimated to cause around 40% of crop losses worldwide. We examine the food security effects of plant clinics, a novel agricultural extension model that aims to reduce crop losses due to pests through the provision of demand‐driven plant health diagnostic and advisory services to smallholder farmers. The study is based on survey data from maize‐growing households in Rwanda, where 66 plant clinics have been established. Using switching regression and matching techniques as well as various food security metrics, including the food insecurity experience scale, we find evidence that participation in plant clinics is significantly associated with a reduction in household food insecurity. For instance, among the participating households, plant clinics contribute to a decrease in the period of food shortage by one month and a reduction in the severity of food insecurity by 22 percentage points. We also show that these effects are more pronounced for female‐headed households. Overall, our findings suggest that plant clinics can play an important role in achieving the Sustainable Development Goal 2 of zero hunger.     

Who determines the trade-offs between agricultural production and environmental quality? An evolutionary perspective from rural eastern China

We explore the evolutionary nature of interactions between government policy, farm decision-making and ecosystem services in Shucheng County, Anhui Province, 1950–2015. Analyses of ecological, social and economic trends are complemented by interviews with local farmers. Since the Household Responsibility System started in 1980, there has been a trade-off between rising levels of provisioning services and falling levels of regulating services with evidence that critical thresholds have been passed for water quality. Using a Framework for Ecosystem Service Provision, we argue that farmers have acted only as ecosystem service providers and have not influenced the policies that have brought about the trade-offs. Over the period, ecological degradation is best described as an example of ‘creeping normalcy’ where cumulative conventional actions by individual farmers produce unsustainable losses in regulating services. The Chinese government should act to balance the various ecosystem services through valuation and national policy. In this respect, there is a need for agencies that can provide place-based advice to farmers that will allow them to maintain productivity levels while pursuing restorative actions. Even with new policies, the draw of urban employment, high production costs and an ageing population threaten the viability of farming in these marginal agricultural areas.     

What Can We Learn from Droppers and Non-adopters About the Role of Advice in Agricultural Innovation?

In this article we assess the diversity of sources of advice identified by 678 adopters, 295 non-adopters and 107 droppers (or dis-adopters, who have ceased or reduced the use) of agricultural innovations across 13 European countries. For most innovations, the volume and composition of advisory supports (e.g. public advisory services, farm business organisations, NGOs, research and development sector, other farmers), at the whole farm level were similar between adopters, non-adopters and droppers. However, there were significant differences in relation to specific innovations. Farmers adopting digital technologies, soil-improving cropping systems, and common management of natural resources identified more diverse sources when assessing innovations, suggesting that more diverse advisory support supported successful implementation. For new on-farm activities, non-adopters had more varied sources of advice than adopters. This demonstrates that non-adoption can be a well-informed decision. Droppers typically identified fewer sources of advice on an innovation than adopters, particularly in the later stages of the innovation process, suggesting that lack of advice impeded successful implementation. The findings suggest that public funding for advisory services could usefully target emergent gaps: to support the provision of up-to-date advice on topics to farmers who have difficulty accessing advice, and to prevent unnecessary dropping by supporting the implementation of innovations.     

Book review

Smallholder farmers who grow diverse landraces in centres of crop diversity contribute to sustaining the capacity of agricultural and food systems to adapt to change by maintaining crop evolution in their fields today, thus enabling humanity to continue to have the broad genetic variation needed to adapt crops to changes tomorrow. Given this fact, the last 20 years have witnessed an ever-growing interest in on-farm conservation of crop infra-specific diversity. While numerous projects to support it have been, and continue to be, implemented worldwide, there has been very little systematic assessment of the extent to which these projects have been effective at contributing to the maintenance of crop diversity on-farm and the creation of associated benefits for the farmers involved. The factors and relationships implicated in attaining conservation and livelihood results are complex, so that a conceptual scheme that brings them together in a simplified but coherent fashion can be extremely useful for the scientists, donors, policy-makers and practitioners concerned. This paper presents a conceptual framework for analysing on-farm projects, the trade-offs involved and assesses their success in a more systematic way.     

Should ‘Impartial’ Advice be a Priority of European Agricultural and Rural Policies?

Recent EU legislation will require Member States to ensure that farm advice which is supported by EU funding is impartial. In this article we present the findings of an online workshop which asked whether this should be a priority for European advisory supports within the Common Agricultural Policy. The answer was ‘no’. At the workshop, results of AgriLink were presented for discussion with international experts. These results highlighted major pitfalls for setting the boundaries of independent advice. Participants from Europe and North America agreed that ‘impartial’ advisors providing or selling only advice are rare in many contexts. Key organisations offering farm advice in many European countries, such as farmers’ cooperatives, often have established relationships with commercial suppliers. Being apparently independent from industry is also not sufficient for ensuring that advice addresses societal issues. Farmers’ choice for advice is more likely to reflect established trusted relationships than the ‘impartiality’ of the advisor. Workshop participants instead argued that policies should focus on increasing transparency (revealing vested interests); investing in ‘back office’ activities to ensure that advisors have access to reliable and relevant evidence; and ensuring that the full range of EU farmers have access to professional advice.     

Worth the Risk? The Behavioural Path to Well‐Being

There is increasing interest in the ‘economics of happiness’, reflected in the volume of articles appearing in mainstream economics journals exploring the major determinants of self‐reported well‐being. We contribute by exploring the factors influencing how satisfied farmers are with their quality of life. We find that farm income, subjective perceptions relating to the adequacy of household income, debt, health and personal characteristics such as age and relationship status are significantly associated with farmers’ self‐reported life satisfaction. While significantly associated with farm income, farm structural variables such as farm size, farm type and the presence of a farm successor were not found to be significantly related with life satisfaction. Our results also suggest that farmers who are more risk averse enjoy significantly lower levels of both life satisfaction and farm income than their more risk seeking or risk neutral counterparts. We suggest that, in the same way that risk aversion inhibits farmers from making choices that could lead to an increase in their income, it may also constrain farmers (and the wider public at large) from engaging in certain types of behaviours that could lead to an increase in their self‐reported quality of life. Finally, we find that while farm income is significantly related to self‐reported life satisfaction, the direct correlation between these variables is weak, suggesting that farmer life satisfaction can be distinct from business success.     

Potential of feed additives to improve the environmental impact of European livestock farming: a multi-issue analysis

Today, less than 3% of the 250,000 plant varieties available to agriculture are in use. Sources of (agricultural) biodiversity are under threat and disappearing in many regions. Increasing industrialisation of agriculture and top-down agricultural research have contributed to this dependence on a relatively few plant varieties. This article argues that new approaches to agricultural development research are needed to conserve agricultural diversity, improve crops, and produce food of quality for all. Such an approach should enable small farmers on marginal lands to participate as equal partners alongside agricultural scientists, fairly sharing their know-how, expertise and seeds. Three case studies illustrate how farmers and plant breeders are working together in a diversity of agro-ecological, socio-economic and political contexts to put these new approaches into practice. New forms of collaboration are producing an increase in diversity and a number of promising improved varieties in terms of yields, agronomic traits and taste. These varieties are showing better adaptation to the local environmental conditions without requiring extra external inputs. Long-term success requires that these efforts be backed up by supportive policies, by actions to ensure that policies are implemented, and where necessary by related legislation.     

Farmers' Buying Selection Criteria of Agricultural Inputs

The Malaysian farmers' selection criteria of agricultural inputs, attitudes towards selecting the inputs, and the influence of socio-demographic factors in the selection of inputs were examined by using a personal interview with vegetable farmers. It was found that farmers perceived quality as most important criteria in selection of inputs, while advertising was perceived as least important. Vegetable farmers have favourable attitudes towards quality, product availability and fair prices, and less favourable attitudes towards advertising influence. The socio-demographic factors such as income, farm size, geographical distribution, education level, and ethnic group (race) have some influence on farmers' selection criteria of agricultural inputs.     

Farmer perception and valuation of seed quality: Evidence from bean and cowpea seed auctions in Tanzania and Ghana

Double blind field experiments and experimental auctions were conducted with bean and cowpea farmers in Tanzania and Ghana to gauge the relative demand for three types of seed products that differ in price and quality: certified, quality declared, and recycled. Whether the cost differential makes these seeds qualitatively different products as reflected in their perceived performance, and whether that translates into farmers’ willingness to pay price premiums, are the research questions addressed by this study. Results indicate that, all else equal, there were significant differences in the perceived quality of the seed products evaluated. Farmers were willing to pay significantly more for their higher rated seed relative to their lower rated seeds. However, for a majority of farmers the magnitude of the premium they are willing to pay for a higher quality seed is less than the current price differential between certified seed and grain. Research and policy implications of these results for legume seed system are discussed.     

Information about Climate Change Mitigation: What Do Farmers Think?

The adoption of new practices by farmers is one of the key strategies to lower greenhouse gas (GHG) emissions from food production. In this context, effective knowledge transfer systems are essential to inform farmers about climate change, and to convince them of the benefits of new technologies. In this article, farmers’ opinions about climate change, their own efforts to mitigate climate change, and their suggestions on how to improve agricultural advice were assessed. To this end, a survey with over 500 livestock farmers was conducted in Ireland. The findings reveal a high awareness of the urgency to address climate change in general, but many farmers also think agricultural GHG emissions are an overstated problem. In addition, half of the surveyed farmers believe that implementing GHG mitigation measures will lower their profits. These findings underline the need to provide effective knowledge transfer to facilitate the uptake of GHG mitigation measures. When asking farmers directly, by way of text analysis, it emerges that simple messages, group and practical advice that is tailored to individual farming situations is important to farmers. As such, this article provides important insights that are of relevance for designing advisory campaigns to promote climate change mitigation.     

COMMUNICATIONS IN AGRICULTURE: RESULTS OF A FARMER SURVEY

This paper discusses the results of a survey of farmers aimed at establishing a contemporary view of both the use of information and advice by farmers and their attitudes towards the various sources through which agricultural information and advice is channelled. The results of the survey suggest that farmers are generally satisfied with the provision of agricultural information and advice. The Agricultural Development and Advisory Services (ADAS), commercial representatives and the farming press continue to play an important role in communicating information and advice to farmers, but the wider uptake of on-farm information technology is yet to be achieved.     

Measuring impacts and adaptations to climate change: a structural Ricardian model of African livestock management1

This article develops a new cross‐sectional methodology that explicitly incorporates adaptation into an analysis of the impacts of climate change. The methodology examines how a farmer will change choices of species and number to adapt to climate. The approach is applied to study Africa, where the impacts of climate change are expected to be the most severe. The results indicate that in warmer places, African farmers switch from beef cattle to more heat‐tolerant goats and sheep. In wetter places, farmers switch from cattle and sheep to goats and chickens. The results indicate that large commercial livestock operations specializing in beef cattle will be hard hit from climate change whereas small farmers who can easily substitute to goats and/or sheep will be more resilient.     

From Circle of Poison to Circle of Virtue: Pesticides,Export Standards and Kenya’s Green Bean Farmers

In response to growing consumer concerns, developed‐country governments have reduced permissible pesticide residue levels in food. Many food retailers have developed even more stringent private food safety protocols relating to pesticide use, storage and disposal and passed them on to their suppliers. Exporters in developing countries enforce these developed‐country pesticide standards (DC‐PS) by subjecting farmers to close monitoring. This study explores the effects of enforcing compliance with DC‐PS on smallholder farmers’ pesticide‐related health costs. Results suggest that enforcing DC‐PS encourages farmers to use protection that lowers pesticide‐induced morbidity, hence reducing farmers’ health costs from pesticide exposure. The study concludes that there are health benefits to family farmers from complying with DC‐PS beyond the acknowledged income generation from selling fresh produce in premium export markets.     

AN APPRAISAL OF CONTRACT FARMING

This article reviews the circumstances under which contract farming, as one form of vertical integration, is necessary to secure rapid and efficient co-ordination and adaptability within systems of food production/marketing/distribution. A review of American experience and attitudes indicates that contracting in the U.S.A. has been successful in matching farm production to the needs of consumers more quickly and economically than otherwise would have been possible. Contract terms have generally been ‘fair’ to United States farmers, partly as a result of a strong co-operative system, including a large number of bargaining co-operatives, but also as a result of strong competition between American agri-businesses. American experience and conclusions can be transposed to British circumstances. However, there should be greater publicity and analysis of contract terms, as well as more complete information on the financial performance of the agri-business operations of conglomerates and other multi-product businesses.     

Perceptions about land use

Although there are only a limited number of rigorous research papers focussed specifically on land use perceptions, there is an extensive literature on: environmental attitudes in general and urban growth in particular, as well as on the land use perceptions of farmers and on public perceptions about the use of land for the production of food and raw materials. A number of key themes emerge. First, the urban public are resistant to urban growth and have an ingrained and deep attachment to ‘traditional’ and romanticised visions of rural land use. Second, farmers, the main managers of land use, have proved resistant to concepts of multifunctional land use. Third, there is a perception gap between the practice of food production as a damaging land use exercise and consumer ignorance about the realities of how food and other raw materials are produced. However, consumers support the ideas of farmers being paid to use their land in a more environmentally friendly way. Fourth, there is a value-action gap between people's perceptions of the land use damage they are doing and their lack of willingness to actually change their behaviours. The drivers behind these perceptions are likely to change as carbon reduction policies begin to impact. So the paper concludes with a discussion about future perceptions and possible behavioural change.     

Farmers,Biodiversity and Plant Protection: Developing a Learning Environment for Sustainable Tree Cropping Systems

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.     

Criteria for a system level evaluation of farm advisory services

Agricultural advisory services are meant to provide farmers with relevant knowledge and networks for innovation, as well as adjustments to policy and markets in agriculture. Despite substantial investment into these services, there has been little evaluation of their performance and impact, in particular at a system level. A system level analysis is especially challenging in countries with a diverse and fragmented advisory community such as the United Kingdom. This paper proposes criteria for assessing advisory services based on a conceptual framework for analysing characteristics of advisory services as a component of the wider Agricultural Knowledge and Innovation System (AKIS). Using the example of the UK, we investigated characteristics pertaining to governance structures, capacity, management and advisory methods. Data were collected in an online survey of 80 agricultural advisory organisations. Findings showed that most criteria for functional advisory services were met: agricultural advisory organisations utilised diverse knowledge sources and cooperated to fill knowledge gaps; there was a stable workforce of advisors who received regular training; advisory organisations were flexible and adaptive; and all relevant advisory topics were covered. However, a number of client groups were not targeted by advisory organisations and some organisations used only a narrow range of advisory methods. The proposed criteria reflect a balance between a thorough assessment of a country’s advisory services and the typically limited time and budget available for regular evaluations. The criteria and associated proxy indicators should be fine-tuned to reflect the individual country’s situation, and quantitative survey data complemented by qualitative data.
