‘I Eat the Vegetables because I Have Grown them with My Own Hands’: Children's Perspectives on School Gardening and Vegetable Consumption

Inadequate vegetable consumption is a global public health concern related to numerous health risks. A promising intervention to increase children's vegetable consumption is school gardening, although earlier studies have shown mixed results. This study explores how gardening might contribute to changed attitudes towards eating vegetables from a child's perspective. Findings are based on qualitative research with children in Amsterdam, the Netherlands. We reflect on how children enact agency regarding their vegetables. Results show that children report that changes occur in their attitudes towards vegetables as they not only eat more vegetables but also advocate the consumption of vegetables at home.     

Work and technological innovation in organic agriculture

Organic agriculture is a sustainable cultivation ecologically, economically and socially. Several researches in organic agriculture have been made from technical perspectives, economic traits or related to ecological aspects. There are practically no investigations into the nature of the technology used in organic agriculture, especially from an ergonomic perspective. From the activity analysis, this study aimed to map the technology used in the production of organic vegetables. Properties producing organic vegetables were selected representing the State of S?o Paulo. It was applied an instrument (questionnaire and semi-structured interview) with their managers and it was made visual records to identify adaptations, innovations and technological demands that simultaneously minimize the workload and the difficulties in performing the tasks and increase work productivity. For some of the technological innovations a digital scanner was used to generate a virtual solid model to facilitate its redesign and virtual prototyping. The main results show that organic farmers have little technology in product form. The main innovations that enable competitive advantage or allow higher labor productivity occur in the form of processes, organization and marketing.     

Racial and sex differences of fruit and vegetable self-efficacy and intake among college students in a rural,southern location

Abstract

Objective: To examine fruit and vegetable intake and self-efficacy among U.S. college students in a rural, Southern location. Participants: Undergraduate students (n?=?1503) enrolled in a university-wide health class at one large public institution during the spring 2017 semester. Methods: Cross-sectional survey data were collected online and analyzed using independent samples t test, one-way ANOVA, and regression. Results: On average, participants did not meet fruit or vegetable intake recommendations. Mean self-efficacy scores were 17.2 (SD?=?3.4) and 16.42 (SD?=?3.7) for fruit and vegetables, respectively, with statistically significant differences observed by sex and race (p?<?0.05). Hierarchical multiple regression results indicated self-efficacy explained 20.9% (fruit) and 29.3% (vegetables) of the variance in consumption. Similar patterns were found for meeting daily fruit and vegetable intake recommendations. Conclusions: Health campaigns are needed to address sex and racial disparities in college student fruit and vegetable intake and self-efficacy.     

The effects of pre-ordering and behavioral nudges on National School Lunch Program participants’ food item selection

This paper examines the effects of pre-ordering and pre-ordering with behavioral nudges on the selection of fruits, vegetables, and low-fat milk by National School Lunch Program (NSLP) participants in a Florida school. After collecting two weeks of baseline data, students in grades four and five were randomly assigned to one of two treatment groups: the first treatment group pre-ordered their lunches online using a unique software program; the second treatment group received behavioral nudges based on United States Department of Agriculture (USDA) MyPlate recommendations while pre-ordering. Student in grades four and seven served as the control group and continued to obtain their lunches through the normal lunch line. Using difference-in-difference regression analysis, we find that students in the first treatment group selected significantly more fruits, vegetables, and low-fat milk during the pre-ordering intervention phase of the study relative to students in the control group, 27.7%, 15.8%, and 16.3%, respectively, while students in the second treatment group selected significantly more fruits (51.4%), vegetables (29.7%) and low-fat milk (37.3%) than students in the control group. In addition, we find the nudge had a statistically significant positive effect in addition to the effect of pre-ordering; students who received the MyPlate nudge while pre-ordering selected statistically significantly more fruits, vegetables, and low-fat milk than students who pre-ordered without nudging.

Hydrology of the Brooklyn Grange,an urban rooftop farm

Intensive agriculture is an emerging theme of green roof technology. Production of affordable, nutritious vegetables for local consumption and stormwater management are among the ecosystem services emphasized in studies of rooftop farming. However, intensive vegetable production requires irrigation, which can reduce stormwater retention, and there is little empirical data from full-scale operational rooftop farms. In this paper, we report the hydrologic performance of the Brooklyn Grange Navy Yard Farm, a 0.61-ha rooftop farm atop an 11-story building in New York City USA. We monitored soil water content, precipitation, irrigation, drainage, and crop yields to provide water balance and water use efficiency. We found cumulative discharge exceeded precipitation by 11% during the entire study period, hence the farm was a net source of water in the urban hydrologic cycle. Depending on crop types, water use efficiency at the Grange was lower than in-ground agriculture in dry regions with high irrigation demands. For the Brooklyn Grange to integrate stormwater management and water-efficient crop production, it will be important to increase soil water storage, to reduce irrigation demands and drainage loss of water while maintaining average soil moisture levels in the range of readily available water between 10 and 100 kPa of soil water tension.     

Costs and benefits for farmers participating in innovative marketing channels for quality food products

The extra benefits and costs for farmers participating in six innovative marketing channels for quality products in Belgium are analysed. A theoretical model serves as an analytical device to structure the qualitative comparisons with the common marketing channel and with direct sale. The analysis is mainly qualitative, because many benefits and costs cannot be quantified exactly. In the analysis, transaction costs are explicitly taken into account because they constitute a real cost when switching from a common to an innovative marketing channel. In all six marketing channels, higher costs are compensated for by higher revenues due to higher prices and a higher turnover and by reduced uncertainty. These factors encourage farmers to enter quality food projects. In addition, we found that co-operation decreases transaction costs and that collective initiatives enable farmers to enter the pathway of quality food production without investing excessive labour or capital.     

Traditional vs. Modern Food Systems? Insights from Vegetable Supply Chains to Ho Chi Minh City (Vietnam)

This article describes the development of vegetable marketing in Ho Chi Minh City (Vietnam), where modern distribution outlets are competing fiercely with traditional traders for wholesale and retail customers. Data from interviews with supply chain stakeholders and a survey of vegetable wholesalers have been used to compare the performance of modern and traditional chains, and the findings reveal the chains as segmented in their product focus, the modern sector focusing exclusively on quality. Modern marketing channels are generally more efficient than traditional ones but still account for only around 2% of vegetable distribution. The article argues that policy‐makers should not promote the ‘modernisation’ of food systems at the expense of traditional channels which meet important consumer needs.

The spaces and ethics of organic food

Initial assessments of the potential for organic food systems have offered an optimistic interpretation of the progressive political and ethical characteristics involved. This positive gloss has prompted a stream of critique emphasising the need to explore the ambiguities and disconnections inherent therein. In this paper, we consider the case of Riverford Organic Vegetables,¹ arguably the largest supplier of organic vegetables in the UK, and suggest that existing debates assume too much about the “goods” and “rights” of organic food and leave important questions about the spaces and ethics of organic food. We argue that, in the case of Riverford, the space of organic food production and distribution is neither the small, local, counter-cultural farm nor the large, transnational, corporate firm. Rather, simultaneously, the spaces of organic food production and distribution are the national network, the regional distribution system and the local farm. In addition, in the case of Riverford, the ethics of organic food exhibit few grand designs (of environmental sustainability, for example). Rather, the ethics of organic food are best characterised as: ordinary, since they relate to concerns about taste, value for money, care within the family and so on; diverse, since multiple practices steer the production and distribution of organic food; and graspable, in that both vegetables and box have material and symbolic presence for consumers.
