What carbon farming activities are farmers likely to adopt? A best–worst scaling survey

Transferring carbon from the atmosphere into terrestrial sinks through carbon sequestration practices (so-called ‘carbon farming’) has been proposed as an important component in Australia’s efforts to mitigate greenhouse gas emissions. We use a Best–worst scaling survey to determine which carbon sequestration practices farmers would be most and least likely to adopt, and what factors were most important in any potential adoption decision. The survey was distributed to dryland cropping and mixed crop-livestock farmers in Western Australia. Farmers ranked improved soil quality and reduced soil erosion as the most important potential co-benefits of carbon farming. Factors discouraging farmers from participating in carbon farming contracts were policy and carbon price uncertainty and the uncertain impact of carbon farming practices on productivity and profitability. Farmers had strong preferences for stubble retention and no-till cropping practices as carbon farming strategies. The practices that farmers preferred least were applying biochar and planting trees. Farm and farmer characteristics, including (lack of) awareness of carbon farming policies and opinions about climate change, influence the potential willingness to adopt different carbon farming practices. Given recent policy uncertainty and farmer preferences revealed in this study, it is important to communicate potential co-benefits (rather than opportunities to earn compensation or carbon credits) to increase farmers’ engagement in carbon sequestration activities.     

Renters,landlords, and farmland stewardship

Are farmers better stewards of the land they own than the land they rent from others? We answer this question using a data set that identifies Ontario farmers’ conservation practices on their own land as well as the land they rent. Using a fixed‐effects regression approach, we find that the role of tenure varies for different types of conservation practices. Farmers were found to be just as likely to adopt a machinery‐related practice such as conservation tillage on their rented land as that land which they own. On the other hand, farmers were found to be less likely to adopt site‐specific conservation practices such as planting cover crops on rented land. However, this effect diminishes as the expected length of the rental relationship increases when the landlord has a farming background.     

Conservation practice complementarity and timing of on-farm adoption

The adoption of conservation practices is a dynamic process. Factors that vary over time can affect farmers’ decision to adopt and adoption timing. We used a duration model to evaluate the farmer's adoption time for continuous no-till (CNT), cover crops (CCs), and the variable-rate application of inputs (VRA). We found that producers who had previously adopted soil conservation practices were more likely to adopt additional complementary practices. Farmers using crop rotation adopted CNT and CCs approximately 48% and 62% faster than farmers without a crop rotation, respectively. The CC adoption time was also reduced by 70% for farmers who had adopted CNT. Complementarities between conservation practices may enhance the benefits from adoption and allow farmers to adopt bundles of conservation practices more quickly over time. This can be taken advantage of in conservation programs by promoting or requiring practices first that enhance adoption of other practices. We also found important heterogeneity in the adoption speed associated with farm management characteristics, producers’ attitudes, weather patterns, and crop prices.     

Reasons for adoption of sustainable land management practices in a changing context: A mixed approach in Thailand

A farmer’s decision to adopt sustainable land management practices often takes place in a changing context. In the Northeast Region of Thailand, rural areas face a deagrarianization process and the dominant farming system – small-scale rice farming under rainfed conditions – is losing its role as the main provider of household income. The study applies a mixed approach to investigate the reasons why farmers adopt sustainable land management practices in this region. This approach involved a quantitative assessment of factors that influence adoption and a qualitative analysis of local actors’ opinions regarding these reasons. Two major reasons were identified: the engagement in diversifying production and the willingness to reduce the amount of time household members spend farming. These two reasons relate to two strategies farmers use to adapt to ongoing changes: getting involved in changing the farm or maintaining it while limiting the effort they spend running the farm. Initiatives to enhance the uptake of sustainable land management practices in the Northeast Region of Thailand would benefit from structuring the support provided taking these two strategies into account.     

Motivations to grow energy crops: the role of crop and contract attributes

Perennial energy crops are a promising source of bioenergy whose production involves production risks, long‐term commitment of land and need for crop‐specific investments without the coverage of crop insurance potentially available for conventional crops. We conduct a choice experiment in five states in the Midwestern and South‐central regions of the U.S. to examine the effect of crop‐contract attributes on the joint discrete‐continuous choice decisions to adopt an energy crop and convert acres to it from a status quo use, while controlling for the effect of various farmers’ risk and time preferences, sociodemographic characteristics, and availability of crop insurance for conventional crops. We find robust evidence that high discount rates, high upfront establishment costs and need for crop‐specific investments create disincentives for adoption and allocation of land to energy crop production. The effects of riskiness of returns and risk aversion are less robust across specifications. The effect of conventional crop insurance on the energy crop adoption decision differs across types of insurance; in particular, farmers with revenue insurance are statistically significantly less likely to adopt an energy crop. Our results have implications for the design of effective contracts and policy incentives to induce the production of energy crops.     

Payments for environmental services to promote “climate‐smart agriculture”? Potential and challenges

Payments for environmental services (PES) have gained wide popularity as approaches to promote environmentally friendly land use or agricultural production practices. Yet academics have also voiced concerns against seeing PES as a panacea. This article discusses whether PES is an appropriate and promising approach to promote so‐called “climate‐smart agriculture” (CSA) practices, which we define as agricultural production practices that contribute to CO₂ emission reductions and/or removals and provide benefits to farmers via increased productivity and profits and reduced vulnerability to climate change. PES appears most promising for the promotion of CSA practices in small‐scale farming contexts with low incomes. Effective design, however, requires solid estimates of cost and benefit flows from CSA adoption over time, accounting for differences in socioeconomic and ecological conditions, and addressing the risk of leakage. Funding for such PES will likely have to come from public sources, and seems most promising where synergies with other objectives such as agricultural development, food security, and climate adaptation or other environmental services exist. The potential of alternative approaches for CSA support such as taxation with rebates for CSA practices, CSA‐related investment support such as microcredits, and hybrid approaches such as conditional microcredit should be further investigated.     

Differential uncertainties and risk attitudes between conventional and organic producers: the case of Spanish arable crop farmers

The growing importance of economic factors in farmers' decisions to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. In general, published analyses so far have not considered differential uncertainties, abilities to control production risk, and farmers' risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between organic and conventional Spanish arable crop farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different production risks as well as different aversions to risk. Organic price premiums and subsidies are found to be powerful instruments to motivate adoption of organic techniques.     

Adoption and Abandonment of Organic Farming: An Empirical Investigation of the Irish Drystock Sector

There is a considerable literature about the adoption of organic farming. However, possible abandonment of organic farming has received scant attention. Thus, relatively little is known about the exit decisions of farmers. In addition, most studies are based on a static framework where it is not possible to account for changes in farmer decisions over time. This article attempts to fill this gap in the literature by investigating the determinants that affect both adoption and abandonment of organic drystock farming over time. The use of duration analysis allows for the consideration of cross‐sectional and time‐varying factors over the study period from 1981 to 2008. Using this dynamic econometric framework revealed a significant time effect on entry and exit decisions. Overall, the results highlight that where no attempt is made to account for exit decisions and time effects, important information about sustainable farmer decisions may not be taken into consideration.     

Factors Affecting Farmers’ Participation in Agri‐environmental Measures: A Northern Italian Perspective

Agri‐environmental measures play an important role in Italian rural areas, as shown by the financial commitment to the Rural Development programmes. However, in contrast with other European Union (EU) countries, policy‐makers still have limited experience on how farmers approach environmental incentive schemes. This paper casts new light on this issue from a northern Italian perspective. The rationale of the farmers’ decision‐making process is explored using two multinomial models. The first explains the probability of non‐participation or participation in one of three specific agri‐environmental measures. The model outcomes show that labour‐intensive farming types and high dependency of household income on farming activity constrain farmers’ participation, whereas previous experience, easy‐to‐implement environmentally friendly farm practices and adequate compensation of extra costs encourage participation. The second model explores the effect of farmers’ attitudes and beliefs on their predispositions towards participation in any of the schemes. The results highlight that, besides income factors, the farm's future in the business, and the relationship with neighbouring farmers and their opinions on environmentally friendly practices all have significant effects on adoption of agri‐environmental measures. The paper concludes by suggesting that farmers’ attitudes and beliefs, as well as the local behavioural influences, have to be taken into account when designing and communicating agri‐environmental measures.     

Innovation and networks in New Zealand farming

The New Zealand government seeks to dramatically increase the value of agricultural exports while concurrently protecting the natural environment. Thus, farmers are expected to adopt pro‐environmental management practices and novel farm technologies. We show that farmers are more likely to adopt new practices and technologies after seeing them demonstrated, but earlier evidence indicates that demonstration is most effectively undertaken within farmer networks. We use multivariate regression to identify the traits of livestock farmers who are innovative by focusing on adoption of pro‐environmental management practices (managing nutrients, soils and pugging) and novel farm technologies (e.g., windmills, computer‐based management systems, automatic sensors and specialised grasses), considering both numbers adopted and timing. We find that dairy farmers are more innovative than other livestock farmers and that higher education levels and stronger environmental norms within the family are strongly associated with innovativeness. In addition, we find that innovators and early adopters have larger networks than other farmers. Moreover, the composition of these networks is much more varied than the networks of less innovative farmers. These findings imply that innovative farmers in New Zealand may also act as connectors for the diffusion of new ideas in farming.     

Herbicide resistance and the adoption of integrated weed management by Western Australian grain growers

Extension programs to encourage farmers to reduce reliance on herbicides by adopting integrated weed management (IWM) practices have met with limited success. Studies aiming to understand the factors that influence farmers' choices of integrated control practices have faced difficulties in variable specification, and have not achieved high explanatory power. Using data from grain growers in Western Australia, where herbicide resistance in major crop weeds is common, this study tests the applicability of a framework for the IWM adoption decision in which herbicide efficacy is assumed to be a potentially exhaustible resource. Farmers' perceptions of multiple techniques and other variables are aggregated using principal components, and used in logistic regressions to explain the intensity of use of IWM practices. Eighty‐six percent of growers were correctly classified according to use of multiple IWM practices. Herbicide resistance and expectations of the future availability of effective new herbicides were significant in explaining IWM adoption. IWM adoption and herbicide‐resistance management are shown to be information‐intensive and involving an intertemporal resource management decision.     

Drivers of adoption of agroecological practices for winegrowers and influence from policies in the province of Trento,Italy

Many agricultural practices are negatively impacting the environment and threatening the ecological foundations of the global food system. Therefore, agroecological practices are being proposed as viable and desirable alternatives. Biophysical, economic, social, and political factors, matched with farmers’ psychological attributes, may all be governing the choice of agricultural practices. Public policies can play a significant role as they can stimulate the adoption of innovative farming practices. The main objective of this research was the evaluation of farmers’ motivations for the adoption of agroecological practices in the viticulture sector in the province of Trento, Italy. A specific focus was laid on the influences from the European Common Agricultural Policy (CAP) measures. For the evaluation of farmers’ perceptions of their systems of practices, the Cognitive Mapping Approach for Analysing Actors’ Systems Of Practices (CMASOP) was applied. Based on information collected during in-depth interviews, Individual and Social Cognitive Maps were generated, representing the most frequently adopted agroecological practices and the major drivers of adoption of such practices, as mentioned by farmers. Drivers of adoption were categorized according to the self-determination theory of human motivations. Farmers reported that adoption of agroecological practices was mainly driven by existence of site-specific pedoclimatic conditions, followed with decreasing importance by requirements from wineries, availability of material, appreciation for aesthetics, health concerns, influence from irrigation consortia, and legal requirements, among which a local legislation for integrated pest management based on a CAP measure. Overall, results show that farmers reported to adopt agroecological practices mainly because of autonomous choices rather than coercion. Therefore, wineries and local policy-makers might incentivize the adoption of agroecological practices by promoting autonomy-supportive policies that foster farmers’ identified and intrinsic motivations.     

Risk aversion in agricultural water management investments in Northern Ghana: experimental evidence

Sub‐Saharan Africa (SSA) is one of the regions in the world most affected by food price volatility and production variability. Poor small‐scale farmers in this region are particularly vulnerable to this variability. As a result, households may be reluctant to adopt new agricultural water management (AWM) technologies when they involve more risk than what they mitigate. Despite risk's role in AWM investments, there have been few attempts to estimate the magnitude and nature of risk aversion in relation to this type of farm decisions. To partially close this gap, this article uses an experimental approach applied to 137 households in Northern Ghana. We find that more than 70% of households are moderately or slightly risk averse. This contrasts with other studies in SSA, where most household decision‐makers exhibit severe to extreme risk aversion. We also find that households that stand to lose as well as gain something from participation in games are less risk averse than households playing gains‐only games. This result suggests that most farmers’ current wealth put them at risk of falling into a poverty trap. Thus, the losses from the riskiest investments on AWM technologies may fall more heavily on the poor, suggesting that additional efforts be given to the creation of viable insurance mechanisms.     

Cereal Technology Interventions for the West African Semi-Arid Tropics

One of the regions of most concern in Sub-Saharan Africa is the geographical area of the West African semi-arid tropics (WASAT) where there has been little impact from the green revolution and most of the region suffers from inadequate and irregular rainfall and low fertility soils. Decreasing per-capita food production trends and 2-3% per-year population growth trends have convinced some to adopt a Malthusian perspective about the future of the WASAT. This paper evaluates the prospects of agricultural technologies and farm management practices that are currently proposed for the WASAT cereal farming system. The technologies are assessed with respect to their agronomic and economic feasibility, risk and their fit within the farming systems. They are ranked as to their feasibility of adoption by farmers in the short, intermediate and long run. The findings suggest that several agricultural technologies are feasible for use in the short run provided that they are used as a package. The complexity and initial high financial and human capital requirements, however, often prohibit farmers from adopting the total package simultaneously. A stepwise approach to adoption is difficult since separate adoption results in lower profitability and higher risk levels. Government policy intervention may be necessary to enable farmers to adopt single technologies en route to total package adoption.     

Descriptive Analysis of Saskatchewan Organic Producers

A total of 69 Saskatchewan organic producers were surveyed in the spring of 1991. Although Saskatchewan organic farming represents a move toward an alternative conventional system of agriculture it is not a complete reversal from conventional practices. Saskatchewan organic farmers are experimenting with highly integrated systems which incorporate green manure crops and soil testing and require high management and marketing skills. In a study of then-goals and objectives using fuzzy sets, environment and healthy food were ranked above farm survival. This leads to the conclusion that most organic farmers do not adopt organic practices based on purely economic criteria but on higher goals within their own hierarchy.     

Risk, uncertainty, and learning in adoption of a crop innovation

Risk and uncertainty have often been suggested as causes of poor adoption of rural innovations, but empirical evidence has been scarce. This study focuses on a new crop‐type, chickpeas, in Western Australia to gather such evidence. The empirical models developed are based on a theoretical framework that conceptualizes adoption as a dynamic decision process involving information acquisition and learning‐by‐doing by growers who vary in their managerial abilities, risk preferences, and their perceptions of the profitability and riskiness of the innovation. Learning encompasses improvements in skill as well as reductions in uncertainty. An annual face‐to‐face survey of over 100 farmers was conducted over 3 years, eliciting the farmers' risk attitudes and their subjective distributions of yields and prices. Two limited dependent variable models, Tobit and Probit, are used to estimate the empirical model. There is a high degree of goodness‐of‐fit for both models. The study provides strong empirical support for the primarily economic character of the adoption decision, and highlight the importance of economic risk in the process. The two risk‐related factors with greatest impact on the adoption decision were risk aversion and relative riskiness of the innovation. Risk aversion tended to reduce adoption, and to do so to a greater extent as relative riskiness and scale increased. Results also reveal the key role that trialing of the innovation plays in adoption.     

Advancing climate-smart-agriculture in developing drylands: Joint analysis of the adoption of multiple on-farm soil and water conservation technologies in West African Sahel

Water stress and soil infertility are the greatest constraining factors for higher agricultural productivity in drylands, prompting the current interest in soil and water conservation (SWC) practices in water-constrained regions. To provide a more comprehensive understanding of challenges surrounding the adoption of SWC practices in these regions, we used a joint analysis framework combining both multivariate and ordered probit models to analyze adoption-decisions for eleven on-farm SWC practices. Our case study, involving 500 farmers from a representative West African Sahelian zone, revealed that although the adoption of SWC practices is widespread in the West African drylands, there is still an important potential to improve and upscale their specific adoption rates. Almost all farmers (99%) used at least one of the eleven practices considered in this study, whereas specific adoption rates ranged from 5% for contour vegetation barriers to 87% for manure application. More than 70% of the farmers used up to three practices only, and less than 30% used between four to nine practices. Many practices are interdependent, with some practices being complementary and others substitutable. The analysis of the determinants of the adoption and the intensity of adoption revealed that SWC practices are labor-, knowledge- and capital-intensive. We found that the major drivers of farmers’ decisions to adopt, as well as to intensify the use of, most SWC practices are the presence of children (aged 6 to 14) in the household, land holding, land tenure, awareness and training on SWC and access to alternative – but non-agricultural labor constraining – cash sources such as remittance and cash farming. A higher number of migrating household members increases the probability of intensifying the use of SWC practices, but only when this is in line with the household’s land endowment and labor needs for farm activities. This comprehensive study will be of significance for a finer understanding of SWC practices in West African Sahel. More generally, it will likely help policy makers to upscale the adoption of sustainable SWC practices for the advance of climate-smart agriculture in developing drylands.

Determinants of herbicide use in rice production in the Philippines

This study identifies farm‐specific and market factors affecting the adoption of herbicides and the level of herbicide use by rice farmers in the Philippines. This requires the application of a modified version of Heckman's two‐step method to estimate a random‐effects double‐hurdle model for unbalanced panel data. The age of the farmer, household size, and irrigation use are significant determinants of the decision of farmers to adopt herbicides as an alternative to manual weeding, while economic variables such as the price of herbicides, total income, and access to credit determine the level of herbicide use. Determinants of both adoption and level are land ownership, farm area, and the method of crop establishment. These results are potentially relevant when designing policies to reduce excessive herbicide use or to encourage the adoption of alternative weed control methods such as integrated weed management.     

Institutional factors and farmers’ adoption of conventional,organic and genetically modified cotton in Burkina Faso

Organic farming and genetically modified (GM) crops technologies are currently being promoted as alternatives to conventional farming that is seen as unsustainable. However, institutional constraints can impede the adoption of even the most sustainable technology. This paper analysed the effect of institutional factors on farmers’ adoption of conventional, organic and GM cotton in Burkina Faso. Building on the expected utility model and institutional theory, a multinomial logistic regression was performed using farmers’ survey data from the 2014–2015 production season. The results showed that subsidies on fertiliser and credit for cereals production, the power of farmers’ association and that of the cotton company favoured the adoption of conventional and GM cotton at the expense of organic cotton. In order to succeed, organic cotton projects need to include components that help farmers to access organic fertilisers for cereals production. They also need to involve the cotton companies that are the most powerful stakeholders of the cotton sector. Extension services are necessary for both organic and GM cotton adoption. Other important factors to consider include farmers’ education, the potentials of the technologies, the good agro-ecological conditions, the continued involvement of women, the availability of virgin lands and the closeness of farmers to their farms.
