Climate-resilient crops and crop varieties have been recommended as a way for farmers to cope with or adapt to climate change, but despite the apparent benefits, rates of adoption by smallholder farmers are highly variable. Here we present a scoping review, using PRISMA-P (Preferred Reporting Items for Systematic review and Meta-Analysis Protocols), examining the conditions that have led to the adoption of climate-resilient crops over the past 30 years in lower- and middle-income countries. The descriptive analysis performed on 202 papers shows that small-scale producers adopted climate-resilient crops and varieties to cope with abiotic stresses such as drought, heat, flooding and salinity. The most prevalent trait in our dataset was drought tolerance, followed by water-use efficiency. Our analysis found that the most important determinants of adoption of climate-resilient crops were the availability and effectiveness of extension services and outreach, followed by education levels of heads of households, farmers’ access to inputs—especially seeds and fertilizers—and socio-economic status of farming families. About 53% of studies reported that social differences such as sex, age, marital status and ethnicity affected the adoption of varieties or crops as climate change-adaptation strategies. On the basis of the collected evidence, this study presents a series of pathways and interventions that could contribute to higher adoption rates of climate-resilient crops and reduce dis-adoption.

This paper examines the resilience of farmers markets in Michigan to the system shock of the global COVID-19 pandemic, questioning how the response fits into market goals of food sovereignty. Adapting to shifting public health recommendations and uncertainty, managers implemented new policies to create a safe shopping experience and expand food access. As consumers directed their shopping to farmers markets looking for safer outdoor shopping, local products, and foods in short supply at grocery stores, market sales skyrocketed with vendors reporting selling more than ever before, but the longevity of this change remains unclear. Our data collected via semi-structured interviews with market managers and vendors, and survey data from customers from 2020 to 21, suggest that despite the widespread impact of COVID-19, there is not sufficient evidence consumers will continue to shop at farmers markets at the rates they did in 2020-21. Furthermore, reasons consumers flocked to farmers markets do not align with market priorities for increased food sovereignty, as increased sales alone are not a sufficient driver for this goal. We question how markets can contribute to broader sustainability goals or serve as alternatives to capitalist and industrial modes of agricultural production, problematizing the role of markets in the food sovereignty movement.

This case study explores a decades long evolution towards a gender-responsive sorghum breeding program in Mali. With known disparities in men and women’s access to the resources that improve agricultural productivity and evidence that gender roles and responsibilities shape knowledge and preferences about varieties, there is need for methods that support gender-responsive processes in plant breeding programs. Gender-sensitive and gender-responsive approaches in plant breeding may increase varietal options available to diverse end-users, increase adoption, and limit negative impacts on vulnerable populations. We assess a participatory plant breeding program in Mali to identify determinants of gender-responsive breeding programs. The analysis uses a case study methodology that draws upon project reports, theses, articles, and experiential knowledge to understand how the sorghum breeding program transitioned over time. This case study details (a) more than a decade of sorghum breeding activities and research that led to (b) the inclusion of women in participatory plant breeding, culinary tests, and large-scale participatory selection in on-farm trials, reaching hundreds of women each year and (c) iterative co-learning processes to develop preferred sorghum varieties and increase sorghum yields on men and women’s fields. Analyses indicated that collaborations among many institutions on-farm with community actors, research across various disciplines such as agronomy and social sciences, context-specific breeding, and long-term funding were essential to increasing gender sensitivity and responsive in the breeding efforts.

A requirement for the successful development of new sorghum varieties in Mali is effective evaluation of grain qualities, since sorghum is a staple food crop on which farmers rely for food security. The diversity of grain quality and social aspects that determine varietal acceptability for processing and cooking, however, make this a challenging task. As the processors of sorghum grain in households, women’s knowledge of grain quality traits can contribute to this work. Our objective is to understand opportunities to use grain quality traits to identify experimental varieties that may contribute to food security. Culinary evaluations were conducted in nine villages across two sorghum production zones. Three teams of women, one per replicate, processed, cooked and evaluated five test varieties in each village. Sensory evaluations were conducted by 25 taste testers per village. The major varietal differences observed included the decortication losses, women’s appreciation for ease of processing, and consistency of the prepared food. The participatory evaluation of the quality testing results led to the development of the concept of ‘food yield’. Discussion of these results focuses on designing cost-efficient grain and food quality evaluations that rely on women’s expertise as processors and strengthens their role in the variety development process.

Purpose: The purposes of this paper are to: (1) characterize farmers’ market manager and vendor perceptions of the economic, social and environmental impact markets have on their local communities; and (2) how those impacts are tracked and communicated to market actors and the local community.Design/methodology/approach: Twenty-nine semistructured interviews were conducted with market managers and vendors across four farmers’ markets within Michigan. The interviews were coded and analyzed using thematic analysis.Findings: Managers and vendors report economic and social and environmental benefits associated with the presence of a farmers' market, consistent with the existing literature. Metrics are tracked to estimate market impact, particularly economic and social benefits. Market managers reported uncertainty about how best to use data internally, and there are gaps in communicating market impacts with vendors. Most data are used for external reporting, to statewide organizations or for grant evaluation. Respondents reported data fatigue and unwillingness among vendors to share personal business information due to concerns about privacy relative to the perceived benefits of sharing data.Practical implications: Additional resources are needed for markets, specifically market managers, to better utilize the data they collect for internal versus external purposes.Originality/value: Metric collection and reporting are a nascent development among markets. Understanding how market actors are utilizing these tools will provide guidance to improve future efforts at impact measurement.
