Biofortification of food crops with iodine is a novel approach to preventing iodine deficiency in humans. The present study analyses the consumer target groups and the market potential of iodine-biofortified fruit and vegetables in Germany. For this purpose, an online survey of 1016 German fruit and vegetable consumers was conducted to investigate the acceptance of different product categories as well as relevant criteria for the market launch. The results show that iodine-biofortified fruit and vegetables are particularly attractive to consumers who purchase at farmers’ markets, organic food shops, and farm stores. Out of this group, 39% of consumers rate such iodine-rich foods as very appealing. They attach importance to food that naturally contains iodine and prefer produce from integrated domestic cultivation. With their focus on sustainability and naturalness, this group of consumers clearly differs from typical users of dietary supplements, who are primarily concerned with health benefits. However, overall about 85% of respondents would prefer biofortified fruits and vegetables to supplements to improve their iodine supply. The greatest market potential for iodine-biofortified fruit and vegetables is to be expected in supermarkets, as this is the preferred food shopping location for most consumers. A total of 28% of those who buy here rate the biofortified foods presented as very appealing. Nevertheless, a successful market launch requires that the benefits of the new products are communicated according to the potential consumer group needs.

Fruits and vegetables are the best food sources of vitamin C. However, fruits and vegetables can be also sources of potentially harmful substances to the human body, nitrates being one of these. The aim of this study was to compare vitamin C and nitrates contents in selected fruits and vegetables from supermarkets and local farmers' markets. Samples of plums, strawberries, apples, spinach, red peppers and tomatoes were chosen for analysis. Content of vitamin C and nitrates was analyzed by HPLC/DAD. The hypothesis was that local market fruits and vegetables contain more vitamin C and fewer nitrates than samples bought in supermarkets. Laboratory analyses showed that there were differences in vitamin C in the case of strawberries, tomatoes and red peppers. The highest level of ascorbic acid was in red pepper samples (141 mg.100g-1). In the case of fruit, the highest content was in strawberries (70 mg.100g-1). As far as nitrates content is concerned, in three cases out of six, the fruit and vegetables we tested from farmers' markets contained lower concentrations of nitrates than those purchased at supermarkets and the hypothesis was accepted in these cases. There was no significant difference between the nitrate content of the local market and supermarket strawberries and red peppers. Tomatoes had significantly higher nitrate content when purchased at farmers' markets than at supermarkets. Leafy vegetables are considered to be the major source of nitrates, and this was confirmed by this study. The highest content of nitrates was in the spinach sample (2969 mg.kg-1). Among all fruit samples, strawberries had the highest nitrates levels (maximum 131 mg.kg-1). The results of this work showed that the content of ascorbic acid and nitrates differs significantly depending on the type of fruit or vegetables.

High tunnels (HT) can reduce negative environmental strains on crop production and have been shown to extend the growing season for many small fruits and vegetables. Because HTs require relatively low initial investment compared with standard greenhouse structures, they are well suited for the small to mid-size grower. HTs provide a practical means of entry into intensive crop production for farmers who direct market their produce. By using HTs, direct market farmers may create a special marketing niche which set's them apart by offering locally grown vegetables, cut flowers, small fruits, and herbs earlier in the growing season and into the fall after frost. This project examined 1) the potential use of HTs for the production of fresh-market tomatoes (Lycopersicon esculentum Mill.) and strawberries (Fragaria spp.) and 2) the seasonal market potential for these crops in Alabama. Viable markets were determined by conducting surveys at regional locations throughout Alabama, such as farmers markets, grocery stores, shopping centers, etc. Upscale restaurants were also surveyed to determine the demand for locally grown herbs. These surveys were used to determine target markets by asking demographic questions and determining spending habits. Justification for establishing a direct farmer-to-consumer market or a direct farmer to restaurant market for HT products was determined.

Biochar is a co-product of advanced biofuels production from feedstocks including food, agricultural, wood wastes, or dedicated energy crops. Markets for soil amendments using biochar are emerging, but little is known about consumer preferences and willingness to pay (WTP) for these products or the depth of the products’ market potential for this product. This research provides WTP estimates for potting mix amended with 25% biochar, conditioned on consumer demographics and attitudes about product information labeling. Data were collected with an online survey of 577 Tennessee home gardeners. WTP was elicited through a referendum contingent valuation. Consumer WTP for an 8.81 L bag of 25% biochar potting mix is $8.52; a premium of $3.53 over conventional potting mix. Demographics and attitudes toward biofuels and the environment influence WTP. Biochar amounts demanded are projected for the study area’s potential market. Optimal prices, profits, and market shares are estimated across different marginal costs of producing biochar potting mix.

The Green Moroccan Plan (GMP) is a national long-term strategy launched by the Moroccan government to support the agricultural sector as the main driver of social and economic development. The GMP involves a labeling strategy based on geographical indications, aimed at protecting and promoting the marketing of locally produced food specialties and linking their specific qualities and reputations to their domestic production region. We evaluated the success of this policy by comparing consumers’ attitudes and preferences toward a local product having a geographical indication label to one without. We conducted a survey of 500 consumers in main Moroccan cities. The potential consumer set for the local product was found to be segmented, indicating the potential for a domestic niche of environmentally aware consumers preferring organically and sustainably produced food. We applied the analytical hierarchy process to prioritize the attributes of the commodities of interest, which underscores the importance of the origin when choosing a local product without origin labeling; for the labeled product, intrinsic quality attributes are considered to be more important. These findings demonstrate the limited promotion of the established origin labeling in the domestic market. Hence, we recommend that the Moroccan government reinforce the labeling scheme with an organic label to increase the market potential of the environmentally aware consumers by ensuring sustainable production of local products.

As a dynamic and multifaceted construct, computational thinking (CT) has proven to be challenging to conceptualize and assess, which impedes the development of a workable ontology framework. To address this issue, the current article describes a novel approach towards understanding the ontological aspects of CT by using text mining and graph-theoretic techniques to elucidate teachers’ perspectives collected in an online survey (N = 105). In particular, a hierarchical cluster analysis, a knowledge representation method, was applied to identify sub-groups in CT conceptualization and assessment amongst teachers. Five clusters in conceptualization and two clusters in assessment were identified; several relevant and distinct themes were also extracted. The results suggested that teachers attributed CT as a competence domain, relevant in the problem- solving context, as well as applicable and transferrable to various disciplines. The results also shed light on the importance of using multiple approaches to assess the diversity of CT. Overall, the findings collectively contributed to a comprehensive and multi-perspective representation of CT that refine both theory and practice. The methodology employed in this article has suggested a minor but significant step towards addressing the quintessential questions of “what is CT?” and “how is it evidenced?”.

Neighborhood Level

Introduction: Consumption of fruit and vegetables is associated with a lower risk of obesity, diabetes, hypertension, and cardiovascular disease . While five or more servings of fruits and vegetables are recommended, only 50% of residents of New York City (NYC) consume two or more servings a day. While food marketing can change individual dietary behaviors, there is limited evidence on the extent to which healthy food marketing strategies—such as community-based and mass-media campaigns—influence fruit and vegetable consumption at the neighborhood level. Agent-based modeling (ABM) has the potential to provide new insights on how healthy food marketing may impact dietary behaviors by simulating interventions, consumption decisions, and interactions among people in different contexts. Hypothesis: Healthy food marketing significantly increases consumption of fruit and vegetables in NYC neighborhoods. The impact of healthy food marketing varies across different neighborhoods depending on population characteristics and the local food environment. Methods: We developed an ABM that takes into account individual and neighborhood-level factors (e.g., age, gender, education, food environment) and influences of social networks (peers, friends, and family) to predict dietary behaviors of individuals at the neighborhood level. Model parameters were estimated from the Food Attitudes and Behaviors Survey, United States Census data, and previous studies. Healthy food marketing can strengthen positive social norms with regard to dietary behaviors. We simulated two hypothetical healthy food marketing interventions that could improve the influence of positive social norms by 5% and 10%, respectively. We predicted the impact of these interventions on the proportion of the population who consume two or more servings of fruits and vegetables across 34 NYC neighborhoods (defined by the United Hospital Fund) in three years. We validated our model using data from the NYC Community Health Survey. Results: The simulation results suggested that the healthy food marketing interventions have the potential to increase the proportion of the population who consume two or more servings of fruits and vegetables over three years: for a 5% improvement on positive social norms, the increase in the proportion was 0.58% - 8.97% by neighborhood; and for a 10% improvement on positive social norms, 2.68% - 13.94% by neighborhood. Exploratory analyses suggested that among population characteristics, a high proportion of population without a high school diploma was associated with lower effectiveness of healthy food marketing in increasing consumption of fruits and vegetables. Conclusions: Healthy food marketing may increase consumption of fruits and vegetables in NYC, but more attention to the mechanisms that account for the lower increase in neighborhoods with low educational attainment is needed.

AbstractObjectiveTo explore the effect of seasonality on fruit and vegetable availability and prices across three outlet types (farmers’ markets, roadside stands and conventional supermarkets).DesignCross-sectional survey of geographically clustered supermarkets, farmers’ markets and roadside stands. Enumerators recorded the availability and lowest price for eleven fruits and eighteen vegetables in each season of 2011.SettingPrice data were collected at retail outlets located in central and eastern North Carolina.SubjectsThe sample consisted of thirty-three supermarkets, thirty-four farmers’ markets and twenty-three roadside stands.ResultsOutside the local harvest season, the availability of many fruits and vegetables was substantially lower at farmers’ markets and roadside stands compared with supermarkets. Given sufficient availability, some items were significantly cheaper (P<0·05) at direct retail outlets in the peak season (e.g. cantaloupe cost 36·0 % less at roadside stands than supermarkets), while others were significantly more expensive (e.g. carrots cost 137·9 % more at farmers’ markets than supermarkets). Although small samples limited statistical power in many non-peak comparisons, these results also showed some differences by item: two-thirds of fruits were cheaper at one or both direct outlets in the spring and autumn, whereas five of eighteen vegetables cost more at direct retail year-round.ConclusionsCommonly consumed fruits and vegetables were more widely available at supermarkets in central and eastern North Carolina than at direct retail outlets, in each season. Contingent on item availability, price competitiveness of the direct retail outlets varied by fruit and vegetable. For many items, the outlets compete on price in more than one season.

 This paper identified and examined the internal and external forces that enable or inhibit the performance of plant clinics in Nepal. The study used web-based online survey tool to collect primary information. Likert scaling and indexing techniques were used on data analysis. Pretested set of questionnaires were mailed to 209 plant doctors and the response rate was 54.54%. Being ninth country to initiate plant health clinics, Nepal is successful to adapt this novel approach into the existing extension system. It has increased access to plant health services by providing wide range of services at a place. However,limited understanding and only profit motive of local private agro-vet and input dealers has created some biased-understanding and un-trust with clinic organizers. This SWOT analysis clearly spells the scope of plant clinics to fulfill the gap between farmers need and existing services provided by public extension system.Journal of the Institute of Agriculture and Animal Science.Vol. 33-34, 2015, page: 137-146

A main current trend is healthy lifestyle and the consumption of fruit and vegetables. The assessment of healthiness of plant-based diet is not so obvious either among the population or food experts. In an online survey the knowledge, beliefs and misbeliefs about plant-based diet were analysed among members and non-members of online social media lifestyles groups. All in all, it can be stated that there are no significant relationships and differences between knowledge, attitude and perception of members and non-members. Social media users are aware of the different types of plant-based diet (vegetarian, vegan) and the positive and negative psychological effects. The associations connected to plant-based diet are the following: healthy, environmentally friendly and expensive. Only a small segment of Hungarian people follow plant-based diet. At the same the diverse and everyday consumption of fruit and vegetables is essential because of health and sustainability issues. Due to conscious nutrition and more plant-based diet, people can contribute to the protection of their own health and the Earth.
