The beekeeping sector plays an important role in maintaining biodiversity and the ecosystem, in addition to its production function. The European beekeeping sector is facing a number of constraints that make it difficult to operate, and the Covid-19 pandemic has posed new challenges for beekeepers. The purpose of the study is to examine the resilience of beekeeping businesses to the most important problems affecting beekeepers and the Covid-19 pandemic. The research analyses the role of marketing and profitability and how they influence the resilience. Variables obtained from online questioning of a representative sample of Hungarian beekeepers (N = 297). Cluster analysis was used to validate the results. Using a Two-step clustering model, three clusters of beekeepers were identified: a non-resilient; a resilient, but not proactive and not very profitable and a resilient, proactive and profitable cluster. According to the research, the resilience of beekeepers is shaped by several factors. Well-trained, long-established beekeepers who seek to differentiate their products from their competitors’ overcome the difficulties caused by the pandemic and other beekeeping problems much more easily. Very important factors resulting in remarkable business resilience are the number of used subsidies and the number of cooperations.

Owing to the different roles of men and women in the family, women may affect family welfare differently than men. Existing research only analyzes the impact of non-farm employment or male non-farm employment on family welfare, and the impact of female non-farm employment on the family has not been addressed in existing studies. China is a particularly interesting case given its rapid economic development and rising rates of female non-farm employment. We used data from the China Health and Nutrition Survey to analyze the dietary patterns of family members and identify the factors that influence food choices and nutrient intake. The results showed that female non-farm employment reduced household protein and calorie intake levels and increased the frequency of dining out among rural household members.

Agricultural Advisory Services (AAS) have always had a central role to play at each juncture in agricultural development and innovation. A transition to sustainable agriculture requires an agri-advisory response which draws on the agency and knowledge of the farmer(s), is more tailored to a particular local context and encourages the sharing of knowledge and experimentation across farms in a landscape. Co-operatives, as collaborative, farmer-owned and embedded entities, would seem to be well placed to play a greater role in this evolving agri-advisory space. However, there would seem to be little recognition of the current or potential role of co-operatives in agri-advice either in academic literature or policy discourse. This paper explores the current agri-advisory offering of Irish dairy co-operatives and their potential to offer an enhanced collaborative and landscape-based offering. It concludes that many of the elements are in place for such an approach but there is a greater need to leverage this potential, appreciate the benefits and enable a more farmer-centred and tailored agri-advisory orientation in co-operatives.

Global blueberry production more than doubled during the last decade. In Mexico, the production of this fruit has grown faster than globally, positioning this country among the top five international blueberry-producing regions. This case study focuses on a prospective investor planning to grow blueberries in Mexico and export most production to the U.S., the largest producer and consumer of fresh blueberries. A high-technology producer growing blueberries under high tunnels in western Mexico is featured in this article. The case study was researched using a combination of field visits to blueberry producers, collaborative work with an industry consultant, and academic research. The article provides industry statistics on blueberries in Mexico and globally over the last decade. In addition, it describes how the authors conceptualized and developed discounted cash flow models to evaluate this potential investment. Despite the importance of blueberries from Mexico, there is a need for financial models to assess the profitability and risk of growing blueberries in that country. Students solving this case are expected to identify risks and opportunities in the industry and conduct Porter’s five forces competitive analysis. In addition, students will mainly evaluate the results of a stochastic capital budgeting model.

Existing research based on labels, risks and benefits, and cultural differences has focused on consumers’ preferences for genetically modified (GM) food products. Limited attention has been paid to the attitudes toward the source who developed the biotechnology. Because there may be trust issues associated with large multinational firms that are often involved in the development of biotechnology, it remains an unexplored question whether consumers consider who produces the technology when forming opinions about food produced with biotechnology. This study investigates consumers’ attitude toward the source of biotechnology using a choice experiment with GM oranges. The study involved participants from three major orange-consuming countries (United States, Germany, and Spain). Results reveal that participants from all three countries were less willing to pay for GM oranges when the technology originated from multinational agribusiness corporations, compared to public universities and small companies. Further examining the effect of consumers’ perceptions, we found consumers’ perception of corporate distrust and environmental concern negatively influence their attitude toward the source of biotechnology, but their technology acceptance positively affects the attitude. By understanding consumers’ attitudes about the source of biotechnology and factors that may improve the consumer reactions, communication and promotion of new biotechnology food products to improve acceptance from existing and potential consumers are discussed.

Consumers are becoming increasingly concerned about the sustainability of their purchases. The coffee industry has been a leader in developing initiatives that promote the adoption of sustainable practices along the value chain. Labels on coffee packages that denote sustainable attributes are intended to inform the consumer and encourage sustainable consumption. The main objective of this study was to analyze consumers’ knowledge of, and preference for sustainable labels (Fairtrade, Organic USDA, Rain Forest Alliance, and 4C) on coffee in Honduras, a developing low-income and high-quality coffee exporting country. The study also evaluated the consumer’s visual attention to sustainable coffee labels. Data were collected using a questionnaire (including a choice experiment) from a sample of 450 consumers, as well as eye-tracking technology (a subsample of 65 consumers). Although Honduran coffee consumers have low levels of familiarity and knowledge about sustainable labels, they are willing to pay premiums for coffee with these labels (10% to 27% relative to average prices). Consumers pay more attention to the Organic USDA label, which is also the label with the highest willingness to pay value. Overall, the study’s results indicate that there is a domestic market for coffee produced sustainably in Honduras.

Both home-grown school feeding (HGSF) and short food supply chain (SFSC) emphasize on proximity and aim to strengthen the competitiveness of local smallholder farmers. From a theoretical perspective, HGSF implemented as a type of SFSC could help deliver synergies. A pivotal question is how HGSF can be combined with SFSC and the benefits and drawbacks of such combination. Using an HGSF program which was implemented as an integral part of a free preschool lunch pilot in South Central China, this paper shows that HGSF and SFSC (in its full term) could be combined through one structured demand intervention. This study uses both qualitative and quantitative materials. Qualitative data were collected through focus group discussions with government and preschool staff, parents or caregivers, cooks, World Food Programme representatives and other stakeholders involved in the pilot program. The quantitative part used both small panel data and cross-sectional data from 106 smallholders. This study analyzes the design, implementation, good practices, benefits and constraints of the HGSF-SFSC model. We find that direct purchase from smallholder farmers was linked with higher income and production and dietary diversity. Moreover, this study identifies several constraints of the current HGSF-SFSC model. The policy implications for sustaining and scaling up the current pilot are discussed in the paper.

Based on panel data from the National rural fixed point survey from 2011 to 2018 and the Peking University digital financial inclusion (DFI) index data, this article uses the dynamic panel fixed effect model to analyze the effect of access to digital inclusive financing platforms on agricultural total factor productivity (TFP) and its contributing factors at the household level. The results show that DFI have a significant hysteresis positive impact on agricultural TFP and its two components, agricultural technical progress and agricultural technical efficiency change. And the usage depth of financial services has the greatest effect in three dimensions of DFI index.
