Despite being generally accepted as a promising conservation practice to reduce nitrate pollution and promote soil sustainability, cover crop adoption in Midwestern US agriculture is low. Based on focus groups, surveys and partial budgets, we calculated the annual net returns to cover crop use for farmers in Illinois, Iowa and Minnesota; and elicited farmers’ perceptions about the pros and cons of incorporating cover crops to their row cropping systems. The novelty of our methodology resides in comparing each farmer's practices in the portion of their cropping system with cover crops (typically small), against their practices in the other portion of their cropping system without cover crops. The resulting comparisons, accounting for farmer heterogeneity, are more robust than the typical effects calculated by comparing indicators across cover crop users and unrelated non-adopters. Our results highlight the complicated nature of integrating cover crops into the crop production system and show that cover crops affect whole farm profitability through several channels besides establishment and termination costs. Despite farmers’ positive perceptions about cover crops and the availability of cost-share programs, calculated annual net returns to cover crops use were negative for most participants.

Poor productivity in smallholder farming systems has necessitated research on the potential of crop–livestock integration to sustainably improve productivity. The study hypothesized that improvement in individual agronomic and livestock systems and synergistic utilization of by-products of either system increases productivity, profitability and integration. Smallholder farming households were classified into: old and resource endowed (OR); part time (PT); and young, risk-taking and enthusiastic (YRE) following a survey conducted in Murehwa and Goromonzi districts of Zimbabwe. Crop–livestock systems’ integration scenarios were developed for each farmer category. Expression of crop–livestock integration in physical terms, e.g., kg ha−1, can be complex and confounding, hence the expression of integration in monetary values. Baseline scenario results indicate that OR had the highest crop–livestock integration of $3981 compared with PT and YRE despite OR having the lowest manure usage compared with PT and YRE farmers. Moreover, OR had the least legume yields of <800 compared with 3530 kg ha−1 in YRE farmers. Subsequent crop–livestock integration scenarios increased maize grain yields by at least 50%, thus increasing profitability to $1210, $3230 and $3100 yr−1 for mucuna, cowpea and groundnut, respectively. Total income increased by 135, 132 and 101% translating to $9880, $2960 and $6290 yr−1 in OR, PT and YRE farmers, respectively. Crop–livestock integration therefore has the potential to improve smallholder crop and livestock productivity, variable with socio-economic status.

Agricultural commodity ‘dumping’ is the practice of exporting commodities at prices below the cost of production. Dumping cheats farmers of a fair return for their work. It cheats both the farmers in the USA who are paid below cost, and the farmers abroad whose crops compete with US exports in markets distorted by dumping. And dumping shortchanges the ecosystems upon which humanity depends for its survival. Neo-classical economics holds that when prices are low, suppliers will produce less. The persistence of dumping in the US agricultural commodity sector defies that assumption. In trade circles, where the problem is acknowledged to an extent, dumping is explained as a result of government subsidies. The authors argue that the dumping numbers provided by the Institute for Agriculture and Trade Policy suggest this explanation is at best partial. They look at definitions of dumping, and explanations for how it arises and why it persists, in defiance of expectations that markets are self-correcting.

Green manure and compost-enriched in phosphorus can promote the sustainability of cropping systems by increasing soil fertility over the long term. They can also be used to manage crop/weed interactions, a key element in guaranteeing an appropriate level of satisfactory crop yields. We studied how green manuring with hairy vetch (Vicia villosa Roth.) and the application of different types of phosphorous-enriched compost affect weed/maize (Zea mays L.) interactions in an organic stockless Mediterranean agroecosystem for two consecutive dry years. Green manure stimulated the expression of maize traits related to a higher competitive ability against weeds, such as early growth, height and leaf area index, while the effect of compost was less clear. Regarding crop/weed competition, both green manuring and a phosphorus-enriched compost application gave a significant advantage to maize. Neither green manure nor compost increased total weed density and biomass compared to the control. Green manuring significantly affected the weed community composition. The relative density of ruderal and competitive-ruderal species (according to Grime's classification) was higher in plots where the green manure was applied. The use of green manure, together with novel composting techniques, significantly affected crop/weed competitive interactions, favoring maize, but also creating favorable conditions for unwanted weed species such as competitive-ruderals. Increasing nitrogen availability in the early growth stages of maize through green manuring can increase crop competitive ability. However, this may not suffice to preserve the system from future weed problems, should potentially detrimental species be selected. Dedicated strategies for the control of emerging weed species may thus be needed.

Price premiums are considered as major purchase barriers for organic products and therefore may prevent organic market growth. For wine, however, prices take a double and conflicting effect: they also serve as quality signal for consumers. Therefore, it is of high relevance to examine if price is a major barrier for organic wine as well.

Even though many studies already examined price behavior for organic wine through surveys and experiments, it is still to be clarified how consumers’ react to price changes in a real market context. So far, no study analyzed consumer preferences for organic labeled wine in daily shopping situations. Through the analysis of the GfK household panel—a high-frequency data set of extensive population coverage—implications for price setting and price promotions in different market segments can be given.

In contrast to previous studies, consumers’ overall price sensitivity was found to be low for organic wine and consumers’ preferred organic over conventional wine. The effect of price as quality cue or purchase barrier and the effect of an organic label on consumers’ behavior varied between price categories. Organic wine was valued highest in the low-price category, whereas no price premium for the organic label was examined in the high-price segment. Price sensitivity was extremely high for organic wine in the low-price segment, while price functioned as quality signal in the premium segment for organic and conventional wine similarly.

This study verified previous stated preference studies on organic wine through the analysis of actual purchase data. Moreover, new insights for price setting in different price categories were generated through the examination of a large amount of disaggregated data on single consumer purchases.

Research on short food supply chains (SFSCs) has experienced a remarkable growth during recent years, offering ample evidence that the creation of such alternative food distribution networks can bring multiple benefits to both farmers and consumers. Nevertheless, farmers' engagement in SFSCs is still limited in many countries. Two studies designed to illustrate the role of competencies in the development of SFSCs are reported in this paper. The first one assessed the influence of farmers' self-perceived competencies on their willingness to participate in SFSCs. The second examined whether the engagement in SFSCs affects the levels of participants' competency needs. Study 1 revealed that willingness to participate in SFSCs is affected by the levels of farmers' competencies on issues pertaining to management, entrepreneurship, marketing, networking and cooperation. Although other factors such as farmers' citizenship behavior, their environmental concern and the perception that engagement in SFSCs can increase farm income are also associated with this willingness, self-perceived competencies represent the most important set of predictors. Study 2 uncovered that participation in SFSCs increases farmers' needs in all the above-mentioned categories of competencies. Taken together, these results indicate that farmers' competencies significantly affect their involvement in SFSCs, and that engagement in SFSCs augments competency needs, thus highlighting the importance of creating spaces that help farmers develop and exploit new capabilities.

Two solid state anaerobic digesters (SSADs), 15 L each, were set up for co-digestion of switchgrass with primary digestate of a liquid anaerobic digester (LAD) and the recirculating leachate. Both the LAD and two SSADs were operated at 50°C. The results showed that the bioreactors were not started up stably until day 16 and day 47 for reactors A and B, respectively. The supplement of LAD digestate or injection of sodium hydroxide (NaOH) into the recirculating leachate readily reinitiated the biogas production to normal daily high rates of the two individual SSADs, one on day 16 and the other on day 47. In contrast to reactor A, there was a longer lag phase for bioreactor B, however, it showed 46.2% [77.9 vs 53.3 L kg−1 volatile solid (VS)] more cumulative biogas yields, and higher reduction rate of total solid, VS, cellulose and hemicellulose of 29.5, 31, 40.6 and 15%, respectively, which was likely due to optimized pH and NaOH pretreated switchgrass during start-up period. Methane contents of biogas increased gradually and stabilized at 50% for both reactors, indicating a normal operation of anaerobic digestion lasted for at least 100 days. The determined parameters of digested residues met China organic fertilizer standard (NY 525-2012) except for high moisture and low total nutrient contents. Therefore, the product of SSAD has the potential value of organic fertilizer. It is concluded that the LAD digestate can be reused as inoculums by co-digestion with agricultural residues for biogas and organic fertilizer production in SSAD.

Nitrogen (N) is a difficult nutrient to manage in organic farming systems, and yield reductions related to N deficiency have been reported in organic systems. Legume-based cover crops offer opportunities for biologically fixed N; however, improved quantification of N contribution is needed for cost-effective N management. A 2-yr experiment was conducted near Corvallis, OR, USA, in 2007 and 2008 to (1) evaluate biomass production and N accumulation from selected cover crop treatments, (2) compare the effects of fall-planted cover crops on broccoli [(Brassica oleraceae L. (Italica group)] yield, (3) estimate the quantity of feather meal-N replaced by cover crops. Cover crop treatments included common vetch (Vicia sativa L.), phacelia (Phacelia tanacetifolia Benth), oats (Avena sativa L.) and the mixtures phacelia plus vetch, oats plus vetch and a no-cover crop (fallow) treatment as the control. Using feather meal as an N source, four rates of N fertilizer (0, 100, 200 and 300 kg N ha−1) were randomized within each cover crop treatment in a randomized, split-plot design. Cover crop biomass and N accumulation differed between the 2 yr of the study. In 2007, total biomass accumulation ranged from 5000 to 10,000 kg ha−1, whereas in 2008, cover crop accumulation was 1500 to 5000 kg ha−1. Biomass of both phacelia and vetch (in mixtures or as sole crops) was reduced by 80% from 2007 to 2008, whereas oat biomass and weed biomass in the fallow plots was reduced by only 40% between the 2 yr. The accumulation of N was also reduced in 2008, with vetch (either as a sole crop or in mixtures) contributing less than a third of total N produced in 2007. In 2007, vetch and vetch-based cover crop mixtures increased broccoli yield compared with the fallow, providing 100–135 kg fertilizer equivalent N ha−1. But due to decreased cover crop biomass and N accumulation in 2008, vetch and vetch-based mixtures failed to increase broccoli yield, providing <20 kg N ha−1 fertilizer equivalence. In 2007, oats grown as a sole cover crop reduced broccoli yield when no supplemental N was applied. In 2008, both phacelia and oats reduced broccoli yield at all N levels, with estimated N fertilizer equivalence values of −80 to −95 kg N ha−1. Although legume and legume mixtures increased broccoli yield in only 1 yr of the experiment, addition of vetch to the mixtures reduced yield loss in both years compared with oats and phacelia grown as sole crops.

There is a need to improve geographical and financial access to healthy foods for limited resource populations in rural areas. Community Supported Agriculture (CSA) programs can improve access to healthy foods in rural and limited-resource populations. However, research is needed to discern the most appealing conditions for a CSA (e.g. price, frequency, food quantity) among rural, low-income customers. The goal of this study was to understand low-income consumers' preferences related to participation in a CSA program, considering price, frequency, food quantity and accessibility (e.g. distance) conditions. A modified exploratory choice experiment exercise was embedded within in-depth interviews to examine willingness to participate in CSA under a variety of conditions among 42 low-income adults with at least one child in the household in North Carolina, New York, Vermont and Washington. Willingness to participate in a CSA under each condition was summed and compared across conditions. Results were stratified by race, number of children and household members and McNemar's test and Student's t-test were used to examine differences in willingness between conditions. Salient quotes were extracted to support themes related to each condition. Our analysis suggests that the ideal CSA would be a full-sized share of eight to nine items of mixed variety, distributed every other week, priced at less than US$15, no more than 10 min further than the supermarket (SM) from their home and preferably less expensive but no more than 20% more expensive than SM prices. CSAs interested in reaching rural low-income populations may benefit from considering these consumer-level preferences.

Nearly two decades into the 21st century, we revisit the topic of changes in the US agricultural system. We focus on trends in structure, technology and policy, and on the increasing influence of consumer preferences on this system, particularly for organic agriculture and local and regional foods. We examine technological innovations in the 21st century, including biotechnology, precision agriculture and indoor farming. Within overall trends toward consolidation, we identify an increasing number of vegetable farms and greenhouse operations, accompanied by a decrease in average size of those operations. We note the shift away from price support toward greater reliance on risk management in farm policy, and also track the impact of food movement trends on recent farm bills. While farm bill policies continue to focus on conventional field crop agriculture, some trends—expanded crop insurance, conservation program support and spending on federal data collection, research and community-based grants, for example—have begun to incorporate the growing movement toward organic, local and regional food systems into the mainstream of US agricultural production and policy.

Conventional agricultural practices can lead to soil erosion and a reduction in soil organic carbon (SOC) content. It has been suggested that less intensive agricultural practices, such as conservation tillage (including no-till and reduced till without soil inversion) may reduce both erosion and loss of SOC. The aim of this study was to determine whether, and why, conservation tillage is used in Scania, which is one of the most agro-intensive regions in Sweden. We also investigated how information on tillage practices is obtained, why one type of tillage may be favored over another, and whether some farmers are more likely to use conservation tillage. The result of this study will benefit policy makers and researchers by pinpointing factors that influence the use of conservation tillage. To collect data, a questionnaire was sent to farmers in Scania in 2016. We found that the majority of the responding farmers used conservation tillage, and that it was more likely to be used if the farmer was highly educated and spent more than 50% of their annual working time on crop production. The use of conservation tillage was also more common if the farm was large and clay soil dominated. Crop rotation was often highlighted as the most important factor influencing the choice of tillage practice, which may be due to crop species requirements. When asked to compare the consequences of reduced tillage and plowing, the perception of farmers using conservation tillage was in general more positive, indicating skepticism toward the practice of reduced tillage until it had been tried. We show that the use of conservation tillage, sometimes in combination with plowing, is widespread in Scania. However, unless changes in, for example, crop rotation and labor requirements occur, the use of conservation tillage will most likely remain the same as today, or only increase slightly in the near future. Farm enlargement may result in an increased conservation tillage use, and so may efforts to educate advisors, increased opportunities for peer-to-peer meetings, and the development of economically viable small farm solutions. Increased conservation tillage may be part of the solution for sustainable crop production, but drawbacks such as increased pesticide use must be addressed further, as well as factors such as crop rotation development and practical knowledge that influence conservation tillage use at the farm level.

Intensive use of external inputs in specialized industrial farming systems has created significant socio-ecological externalities, including water and air pollution from nutrients and pesticides, soil erosion and depletion of carbon stocks, biodiversity loss and rising production costs. Ecological intensification is a strategy for reducing reliance on inputs by intentionally designing agroecosystems to harness biological processes and ecological relationships for the sustainable functioning of the system. Incorporating perennials and diversifying systems are two avenues for achieving ecological intensification, and both are characteristics of agroforestry. This preliminary report uses examples of agroforestry in the US state of California as a proof of concept to explore the agronomic and economic feasibility and sustainability benefits of agroforestry in intensive irrigated and temperate farming systems. An exploratory study of farmers experimenting with agroforestry systems and other agricultural professionals identified eight different variants of agroforestry systems being practiced on prime agricultural land in California, ranging from simple use of winter cover crops in orchards to multi-storied cropping systems with integrated grazing. Respondents noted benefits of reduced inputs and production costs, and better nutrient cycling, soil health and pest control. Trade-offs and challenges included increases in labor requirements and management complexity. Knowledge gaps included lack of guidance in biophysical systems design, lack of clarity about economic tradeoffs, and lack of information about ecosystem services benefits. In light of interviewees’ responses, we discuss the constraints and factors needed to foster the successful expansion of agroforestry systems in California and other regions characterized by industrialized farming.

In the search for alternative practices to chemical soil fumigation (CSF), anaerobic soil disinfestation (ASD) has proven to be a promising tool for soil-borne pest management and crop production improvement. The ASD treatment with composted poultry litter (CPL) and molasses (M, a labile carbon source) was identified as an effective approach for a biologically based soil disinfestation system in tomato (Solanum lycopersicum L.) production in Florida. However, environmental and food-safety concerns are associated with animal manure-based amendments, which led to the exploration of composted yard waste (CYW) as a potential substitute for CPL in ASD application. In this study, field trials were conducted in Citra and Immokalee, FL to examine the effects of ASD using CYW, CPL and M compared with a commercially available microbial amendment system on root-knot nematodes, weeds, fruit yield and quality of fresh-market tomato. Treatments included (1) ASD with CPL (11 Mg ha−1) and M (6.9 m3 ha−1) (ASD0.5), (2) ASD with CYW (26.9 Mg ha−1) and M (CYW1 + M), (3) ASD with CYW (13.5 Mg ha−1) and M (CYW0.5 + M), (4) Soil Symphony Amendment (SSA), (5) CYW (26.9 Mg ha−1) alone (CYW1) and (6) a combination of CYW1 + SSA, in comparison with (7) untreated control and (8) CSF (Pic-Clor 60 at 224 kg ha−1). Cumulative soil anaerobiosis was greater in ASD0.5 compared with all the other treatments. The root-knot nematode gall index ratings on the tomato crop were significantly lower in CSF, ASD0.5, CYW1 + M and CYW0.5 + M than untreated control in Citra. Although CYW1 and SSA alone had a moderately suppressive effect on weed coverage and root-knot nematodes, their positive impact on crop performance was limited when used alone. ASD0.5, CYW1 + M and CSF had significantly higher marketable and total fruit yields than untreated control in both locations, while all treatments showed promising results in the Immokalee trial in comparison with untreated control. In general, few differences in major fruit quality attributes were found. Although using CYW in ASD was not as effective as CPL in creating soil anaerobic conditions, the enhanced crop performance in CYW1 + M and CYW0.5 + M suggests the potential of using CYW as an alternative source of organic amendment in combination with M to achieve benefits similar to those obtained with CPL-based ASD.

The Supplemental Nutrition Assistance Program Education (SNAP-Ed) aims to prevent obesity and chronic disease among SNAP-eligible families by facilitating healthy eating and active living. This study aimed to capture the voices of California SNAP-Ed eligible parents to inform program planners of their challenges in feeding their families, their available supports and priorities for intervention. We conducted eight focus groups with 55 participants across five counties in California from May through August 2017. Trained researchers used Dedoose to code and analyze data for substantive themes and overarching findings.Ten key findings and 4 additional findings were identified. Participants experience multiple challenges, primarily inadequate income and limited access to high quality, affordable healthy food contrasted with easy access to affordable unhealthy food. Despite efforts to manage food resources, most struggle to afford adequate diets. Employed parents confront a particularly challenging dual poverty of money and time. Many parents report feeling guilt related to feeding their children. Participants appreciate available programs and services and suggest increasing community input; providing sustainable programs; lowering the cost of and improving access to healthy food; reducing access to unhealthy food; modifying food assistance efforts; and improving nutrition education and promotion. Overall, low-income parents in California struggle to feed their families the way they would like. Participants generally understand what to feed their children, but struggle with how to do it, perceiving their circumstances and environments as inhospitable to healthy eating. Participants' suggestions can help SNAP-Ed programs and other efforts better support families' needs.

The complexities of the global agri-food system and the singular importance of food as a primary good elevate the need to explore what corporate social responsibility (CSR) might mean for agri-food firms. Although CSR refers to voluntary actions on the part of capitalist firms to exceed legal and regulatory requirements, those requirements are important because they set the institutional foundation for what a firm must do to earn the CSR label. In the case of CSR for agri-food firms, the institutional context includes the regulatory state as well as the publicly supported agricultural and food research and development that tends to be done at universities. The purpose of this paper is to provide greater conceptual clarity to the blur between the state, agri-food firms, and universities and their respective responsibilities to the public. Since the globalization of the agri-food system and the emergence of private forms of governance signal the decline of the state's legal and regulatory influence on corporate firms, we pay particularly close attention to the ethical challenges that have surrounded university–agribusiness collaborations—initiatives, which conjoin the moral concerns associated with each respective institution while also raising new questions in their own right. Although the university would ideally play a critical participatory role in this process by virtue of its public commitments, as we explain, the historical relationship between the university and agri-food firms has complicated the university's potential standing as an independent arbiter. Upon examining each of these issues in greater detail, we conclude the paper with a blueprint for how universities can enhance their ethical leadership when engaging with agri-food firms.

Kernza® intermediate wheatgrass (Thinopyrum intermedium) is a novel perennial grain and forage crop with the potential to provide multiple ecosystem services, which recently became commercially available to farmers in the USA. The viability and further expansion of this promising crop require understanding how it may fit the needs of farmers’ livelihoods and the structure of their farming systems. However, no prior research has studied the perceptions and experiences of Kernza growers. The goals of this research were to understand why farmers grow Kernza, how Kernza fits into their systems and identify challenges for future research. We conducted in-depth interviews with ten growers in the North Central USA during the summer of 2017, who accounted for a third of the Kernza farmers in the USA at the time. All farmers had a positive attitude toward experimentation and trying new practices, and they were interested in Kernza for its simultaneous ecological and economic benefits. Kernza was marginal in terms of area, quality of fields and resources allocated in the farm systems, which also meant that farmers maintained low costs and risks. Growers utilized and valued Kernza as a dual-use crop (grain and forage), sometimes not harvesting grain but almost always grazing or harvesting hay and straw for bedding. Weeds were perceived as a challenge in some cases, but Kernza was valued as a highly weed-suppressive crop in others. Farmers requested information on optimal establishment practices, assessment of forage nutritive value, how to maintain grain yields over years, weed management, markets and economic assessment of Kernza systems. These results agree with other cases on sustainable practices adoption showing that engaging farmers in the research process from the beginning, identifying knowledge gaps and testing management alternatives are critical for the success and expansion of novel agricultural technologies.

This paper focuses on systems producing short rotation coppice willows (SRCW) in chickens’ free-range areas. We aim to map chicken farmers’ motivation to implement SRCW, and to assess the economic viability of these systems. Semi-structured interviews were conducted with 18 free-range chicken farmers. Farmers agreed that chickens would prefer SRCW over grassland, which could benefit chicken welfare. They expected establishing an SRCW system would be labor intensive, and doubted if it would be a profitable investment. Some concerns of farmers might be taken away by exchanging information with farmers with SRCW experience. A partial budget analysis was performed to calculate the net present value (NPV) of six different scenarios, differing in the type of chickens, in whether the produced biomass was sold or valorized on-farm and in harvest pattern, all over a 23-yr period. The NPV was positive but low for all scenarios. A sensitivity analysis showed that changes in biomass yield, wood chip price, a price premium for poultry products and current fuel price were most likely to influence the NPV. A risk analysis revealed that NPVs were positive in the majority of the modeled cases. Scenarios in which biomass was used for on-farm heat production showed the highest risk of a negative NPV. A price premium for poultry products may be most effective at increasing profitability, but may only be feasible for farms selling directly to consumers. Establishing a solid market for biomass energy, including guaranteed demand and availability of appropriate machinery for cultivation, may mitigate farmers’ concerns.

The former Deputy Administrator of the US Department of Agriculture (USDA) Supplemental Nutrition Assistant Program (SNAP) nutrition assistance program summarizes her experiences as the lead policy official for the program during the Great Recession under President Obama, specifying observations on how immigration impacts SNAP access for SNAP-eligible clients.

Invertebrate seed predators (ISPs) are an important component of agroecosystems that help regulate weed populations. Previous research has shown that ISPs' seed preference depends on the plant and ISP species. Although numerous studies have quantified weed seed losses from ISPs, limited research has been conducted on the potential for ISPs to consume cover crop seeds. Cover crops are sometimes broadcast seeded, and because seeds are left on the soil surface, they are susceptible to ISPs. We hypothesized that (1) ISPs will consume cover crop seeds to the same extent as weed seeds, (2) seed preference will vary by plant and ISP species, and (3) seed consumption will be influenced by seed morphology and nutritional characteristics. We conducted seed preference trials with four common ISPs [Pennsylvania dingy ground beetle (Harpalus pensylvanicus), common black ground beetle (Pterostichus melanarius), Allard's ground cricket (Allonemobius allardi) and fall field cricket (Gryllus pennsylvanicus)] in laboratory no choice and choice feeding assays. We compared seed predation of ten commonly used cover crop species [barley (Hordeum vulgare), annual ryegrass (Lolium multiflorum), pearl millet (Pennisetum glaucum), forage radish (Raphanus sativus), cereal rye (Secale cereale), white mustard (Sinapis alba), crimson clover (Trifolium incarnatum), red clover (Trifolium pratense), triticale (×Triticosecale) and hairy vetch (Vicia villosa)] and three weed species [velvetleaf (Abutilon theophrasti), common ragweed (Ambrosia artemisiifolia) and giant foxtail (Setaria faberi)]. All four ISPs readily consumed cover crop seeds (P < 0.05), but cover crops with hard seed coats and seed hulls such as hairy vetch and barley were less preferred. Our results suggest that farmers should select cover crop species that are avoided by ISPs if they plan on broadcasting the seed, such as with aerial interseeding.

The dehesa agroforestry system is classified as one of the most singular ecosystems in the European Union. In the southwest of the Iberian Peninsula, it spreads over an area of approximately 6.7 million hectares, contributing major environmental, cultural, aesthetic and economic value to the region. The main agricultural activity that is developed in this ecosystem is the extensive farming of cattle, sheep and Iberian pigs with low stocking density and few inputs. Sustainable management of these ecosystems' existing production farms is essential in order to secure their continuity, as they face a difficult situation on account of their low profitability. One of the strategies that could be employed to attain a sustainable situation is the proposition of an organic production model. In order to explore this option, a participatory research process has been proposed and developed in the Spanish region called Extremadura (Spain). The aim of this process is to investigate the potential of extensive farming systems in moving toward a sustainable organic production model, identifying the main barriers preventing livestock farmers from converting to the organic model and seeking specific improvement measures that would reduce such barriers. For that purpose, four focus group sessions were run with a total of 33 participating stakeholders. For the analysis of these focus groups, Atlas.ti qualitative software was used to categorize and quantify the main ideas proposed during the sessions. The findings revealed that the main barriers can be classified into three groups: barriers that are inherent to the production processes and the structure of the specific sector, barriers associated with administration and management issues and lastly, barriers relating to education and training of the various actors involved. We consider this paper may contribute to policy makers' decisions to focus on specific actions for improvement that are customized for the socio-economic and environmental conditions of the region.
