Assess to quality diets is a basic human right. Geographical challenges and cultural traditions have contributed to the widespread malnutrition present among ethnic minorities of mountainous areas in Northwest Vietnam. Home gardens can play a role in increased diet diversity and micronutrient intakes. However, low production yields and plant diversity in ethnic home gardens have limited their contributions to household food security and nutrition. The pilot study tested a home garden intervention in weekly vegetable harvests and increasing household (...) production and consumption of diverse vegetables year-round. Food ethics issues encountered included limited access to quality food by resource-poor groups, conflicts arising from low preference and value given to some nutritious foods, limited access to information and technology for food production and consumption, each of which were addressed in the study design. The intervention includes: (1) nutrition-focused home garden training and (2) locally-adapted home garden packages consisting of garden planning, technical assistance, and high-yielding seed varieties. Twenty households from two ethnic villages in Son La province participated in the study and were randomly assigned into two groups (intervention and non-intervention). The total vegetable supply from weekly harvests of home garden produce was significantly higher in the intervention households (226 kg) compared to the non-intervention households (39 kg). The intervention group yielded 5.8 and 1.7 times more vegetables by weight and weight per area than those without the intervention. The vegetables were mainly consumed at home for both groups, but the intervention households gave more vegetables as gifts to neighbors. The intervention group cultivated a higher diversity of vegetables with a total of 42 different vegetables compared to 24 in the non-intervention group, which is reflected in an overall higher nutritional yield of vitamin A, iron, other micronutrients and phytochemicals. The home garden training significantly improved the amount, diversity and continuity of household food and nutrient supply. The home garden model is effective and could be scaled up to improve household vegetable supply and consumption, particularly in Northwest Vietnam. (shrink)

In this chapter, I investigate the metaphysical assumptions that medieval thinkers considered necessary in order to integrate the vegetative powers and processes into their conception of human beings as composed of a material body and an immaterial soul. My aim is to show that vegetative powers and processes are central to the late medieval debate on faculty psychology and on the unity or plurality of substantial forms. The chapter has two parts. First, I present three different accounts of the ontological (...) status of the vegetative powers in relation to the body and the soul, as found in Thomas Aquinas, William of Ockham, and John Buridan. All three maintain that the vegetative powers belong to the soul but disagree as to whether they are identical with it or somehow distinct from it, especially when the soul in question is immaterial. Second, I investigate how medieval thinkers accounted for the metaphysics behind the operations of the vegetative powers in human beings, who are endowed with immaterial souls, in particular when it comes to procreation and digestion. A pressing problem for the vegetative powers of human beings is how they can produce a new substance when this composite is supposed to include an immaterial soul which is not naturally generated. Regarding procreation, one can distinguish two different approaches: dispositional generation of material conditions and substantial generation of the body. A similar problem for human beings arises in nutrition and growth once this process is taken to be some kind of substantial change, namely, the corruption of food and the production of new parts of the living being. Two accounts can be distinguished: “transmateriation” of the matter of food into the nourished body and generation of parts of the body. (shrink)

The present investigation studies buying and selling encounters in a Mexican fruit and vegetable shop. It is a conversation-analytic study that shows aspects of the institutional character of these interactions, their overall organisation and sequential structure. It suggests that the core sequential structure of these encounters consists of two base adjacency pairs, buying and selling. In particular, the analysis describes the preparatory characteristics of the pre-expansions that precede the product request formulations, the linguistic composition and sequential positioning of request (...) formulations, the insertions of the buying adjacency pair and the sequencing of the commercial exchange which is described as the climax of the institutional event. The designs of the first pair part of the selling adjacency pair and the product request formulations are presented as clear instances of the referential framework or common ground shared by seller and customer.

Technologies and services provided to resource-poor farmers need to be relevant and compatible with the context in which they operate. This paper examines the contribution of extension services to the food security of resource-poor farmers in a rural village in South Africa. It considers these in terms of the local context and the production of African vegetables in household food plots. A mixture of participatory, qualitative and quantitative research tools, including a household survey, is used to argue that local (...) production practices contribute more to food security requirements than the extension services. This is because of the ability of African vegetables to grow relatively well in semi-arid areas where other exotic plants do not, their ability to provide at least two foodstuffs during their life cycle, and the ability of either the fruit or the leaves, or both, to be dried and stored for consumption in the winter months. These crops can make a significant contribution in terms of household food security, but a number of social and agroecological factors are constraining their production and placing their availability under threat. Despite this, the extension services remain focused on certain activities within vegetable garden projects, even when these are not meeting their proposed purpose—food security by means of cash-crop production. The paper concludes that social and agroecological constraints could be improved if the extension services were changed. This could include the use of context specific and low-cost technologies to ensure that these crops are able to increase their contribution to household food security for resource-poor farmers in semi-arid areas.

The compilers of the Hippocratic gynaecological treatises often recommend sexual intercourse as part of treatments for women’s diseases. In addition, they often prescribe the use of ingredients that are obvious phallic symbols. This paper argues that the use of sexual therapy in the Hippocratic gynaecological treatises was more extended than previously considered. The Hippocratic sexual therapies involve a series of vegetable ingredients that were sexually connoted in antiquity, but have since lost their sexual connotations. In order to understand the (...) sexual signification of products such as myrtle and barley, one must turn to other ancient texts, and most particularly to Attic comedies. These comedies serve here as a semiotic guide in decoding the Hippocratic gynaecological recipes. However, the sexual connotations attached to animal and vegetable ingredients in these two genres have deeper cultural and religious roots; both genres exploited the cultural material at their disposal.

As demand for locally grown food increases there have been calls to ‘scale-up’ local food production to regionally distribute food and to sell into more mainstream grocery and retail venues where consumers are already shopping. Growing research and practice focusing on how to improve, expand and conceptualize regional distribution systems includes strategies such as value chain development using the Agriculture of the Middle framework. When the Ohio Food Policy Advisory Council asked how they could scale-up the distribution of Ohio (...) fresh fruits and vegetables to Ohioans, we decided to use this practical opportunity to not only provide recommendations to this council, but to simultaneously contribute to the literature on AOTM, value-based and spatially–proximate relationships, and conceptualizations of food system hybridity. We do this while examining an entire sub-sector of the Ohio agricultural economy, namely fruit and vegetables and applying the AOTM framework beyond the farm, namely to distributors and retailers. Through interviews with Ohio retailers and a survey of all fresh fruit and vegetable distributors Ohio we: Describe current distribution systems within the state; Identify firms interested in scaling-up distribution, and; Inform state-level policy efforts by identifying opportunities to better target any state-level policy and program efforts. We demonstrate support for the concept of AOTM applied beyond the farm, for value chain development strategies that can transmit ‘quality’ via spatially proximate supply chains, and support for considering hybrid solutions, such as piggybacking for scaling-up local food systems. This work highlights the role a statewide food policy council can have in facilitating market development and their unique position to provide public sector and institutional support to facilitate meaningful connections in the food system.

In response to the chronic overuse and misuse of pesticides in agriculture, governments in Southeast Asia have sought to improve food safety by introducing public standards of good agricultural practices (GAP). Using quantitative farm-level data from an intensive horticultural production system in northern Thailand, we test if fruit and vegetable producers who follow the public GAP standard use fewer and less hazardous pesticides than producers who do not adhere to the standard. The results show that this is not (...) the case. By drawing on qualitative data from expert interviews and an action research project with local litchi (“lychee”) producers we explain the underlying reasons for the absence of significant differences. The qualitative evidence points at poor implementation of farm auditing related to a program expansion that was too rapid, at a lack of understanding among farmers about the logic of the control points in the standard, and at a lack of alternatives given to farmers to manage their pest problems. We argue that by focusing on the testing of farm produce for pesticide residues, the public GAP program is paying too much attention to the consequences rather than the root cause of the pesticide problem; it needs to balance this by making a greater effort to change on-farm practices.

Lead (Pb) contamination of the environment is an important human health problem. Children are vulnerable to Pb toxicity; it causes damage to the central nervous system and, in some extreme cases, can cause death. Lead is widespread, especially in the urban environment, and is present in the atmosphere, soil, water and food. Pb tends to accumulate in surface soil because of its low solubility, mobility, and relative freedom from microbial degradation of this element in the soil. Lead is present in (...) soil as a result to weathering and other pedogenic processes acting on the soil parent material; or from pollution arising caused by the anthropogenic activities; such as mining, smelting and waste disposal; or through the adoption of the unsafe and unethical agricultural practices such as using of sewage sludge, and waste water in production of vegetable crops or cultivation of vegetables near highways and industry regions. Lead concentrations are generally higher in the leafy vegetables than the other vegetables. Factors affecting lead uptake included its concentration in the soil, soil pH, soil type, organic matter content, plant species, and unsafe agriculture practices. Generally, as Pb concentration increased; dry matter yields of roots, stems and leaves as well as total yield decreased. The mechanism of growth inhibition by lead involve: a decrease in number of dividing cells, a reduction on chlorophyll synthesis, induced water stress to plants, and decreased NO 3 - uptake, reduced nitrate and nitrite reductase activity, a direct effect of lead on protein synthesis, a decrease on the uptake and concentration of nutrients in plants. The strategies to minimize Pb hazard can be represented in: (a) Phytoremediation, through natural plants are able to bio-accumulate Pb in their above–ground parts, which are then harvested for removal such as, using Indian Mustard (Brassica juncea), Ragweed (Ambrosia artemisiifolia), Hemp Dogbane (Apocynum cannabium), or Poplar trees, which sequester lead in its biomass. (b) Good and ethical agricultural practices such as cultivation of vegetables crops as far from busy streets or highways and industry regions as well as nonuse of sewage sludge and waste water in cultivated soils. (c) Increasing the absorptive capacity of the soil by adding organic matter and humic acid. (d) Growing vegetable crops and cultivars with a low potential to accumulate lead, especially in soils exposed to atmospheric pollution. (e) Washing of leafy vegetables by water containing 1 % vinegar or peeling roots, tubers, and some fruits of vegetables before consumption may be an important factor in reducing the lead concentration.

The aim of this paper is to analyze the transformation of a tradition of husbandry from moral and political philosophy to natural magic and technology. In the early 1640s there was a shift of approach in the Hartlib circle from the ecclesiastical peace projects to the more experimental and practical projects of husbandry. The discipline of vegetable philosophy defined a new field of interest which could connect the Baconian tradition of experimentation, the desire to compile natural histories, and the (...) dedication to the open character of knowledge and human benefits. I will claim that vegetable philosophy, although operational and practical, and based on the production of transferable technologies, is still grounded on a set of metaphysical assumptions. (shrink)

Increased pressures on agri-food systems have indicated the importance of intermediaries to facilitate sustainability transitions. While producer organizations are acknowledged as intermediaries between individual producers and other food system actors, their role as sustainability transition intermediaries remains understudied. This paper explores the potential of producer organizations as transition intermediaries to support producers in their needs to adopt sustainable production practices. Ten cases of producer organizations in conventional (regime) and organic (niche) vegetable systems in Uruguay were studied qualitatively. Findings (...) show that the classic intermediary roles that producer organizations fulfil in food systems also address the needs of producers in their transition to sustainable food systems. By providing organic inputs, organizing access to output markets, sharing knowledge, and facilitating sustainable production practices, producer organizations support producers within and across regime and niche. Producer organizations mostly function as implicit transition intermediaries, facilitated by their legitimacy among producers, their embeddedness in rural networks, and by refraining from taking a strong normative position. Producer organizations have the potential to be more explicit transition intermediaries, however this position comes with limitations. We provide policy recommendations to optimize the transition intermediary potential of producer organizations in their facilitation towards sustainable food systems. (shrink)

In this paper, I propose an ontological-hermeneutical approach to the question of vegetative life. I argue that, though it is a product of the metaphysical traditionthat from Aristotle to Nietzsche ascribes to the life of plants but a single function, the notion of plant-soul is useful for the formulation of a post-metaphysicalphilosophy of vegetation. Offered as a prolegomenon to such thinking about plants, this paper focuses on the multiplicity of meanings, the obscurity, and thepotentialities inherent in their life.

A field study collecting behavioral data was conducted to investigate effects of behavioral interventions, commonly known as nudges, in promoting the consumption of organic fruits and vegetables. Consumption, both organically and conventionally produced fruits and vegetables, was measured in a grocery store during 4 days where consumers were exposed to informational messages in combination with either emotional images or social norm messages. Measurements of daily consumption without exposure to nudges were carried out during four other days. The results showed no (...) effect of the nudging strategy; instead, it pointed to the importance of the price as a determinant of buying decisions. Buying ecological alternatives was associated with lower price differences between the ecological and non-ecological alternatives. We conclude that combined nudges and collected psychological data from participants may contribute to more successful nudging interventions. Some political measures in balancing the price difference between organically and conventionally produced products might also be interesting strategies in order to promote the consumption of organic fruits and vegetables.

A major programme of irrigated rice extension in the Middle Senegal River Valley has further limited the river’s natural flooding in the floodplain (Waalo), initially reduced by drought. We conducted a transdisciplinary (TD) and gendered study in the region to explore links between agricultural biodiversity and family diets using a social analysis of women’s practices. The results showed how rice expansion impacts local agrobiodiversity, diet quality and the cultural way of life. Disappearance of the singular agropastoral and fishing system of (...) the Senegal River Valley is profoundly modifying the landscape, limiting wooded riverine settings, and is undermining the traditional diversified flood-recession cropping system in the Waalo. This is causing an overconsumption of rice by reducing alternative food sources, such as sorghum, vegetables and animal products (fish, milk and meat). In particular, flood-recession sorghums are in danger of disappearing, yet they are more nutritious than rice and now sell for twice as much, or more. The way of life is being disrupted, notably sociabilities previously based on territorial complementarities, and women are disadvantaged in terms of recognition and added workload. Women’s groups have launched collective irrigated gardens, organic or not, only supported by the local NGO, but any surplus is hardly ever sold on the weekly markets in the neighbourhood. Moreover, this diet imbalance increases nutritional risk factors for health, such as vitamin and iron deficiencies, especially for women, hypertension and diabetes. We argue that, firstly, gendered TD experiences are relevant for documenting women’s activities in order for them to gain political support and, secondly, that targeting women’s care tasks gives more value and impact to TD research results.

Using data from a survey of certified organic or in-transition to organic vegetable and dairy producers in Canada, we seek to understand a farmer’s decision to convert to organic production by exploring the motives, problems and challenges, and benefits of transition to organic. Results suggest that health and safety concerns and environmental issues are the predominant motives for conversion, while economic motives are of lesser importance. In contrast to the extant literature, results suggest that the motives underlying transition (...) have not changed overtime in Canada. Problems experienced during transition relate to lack of governmental and institutional support, negative pressure from other farmers and farm groups, and lack of physical and financial capital. Reduced exposure to chemicals and improved food quality were highly ranked benefits, while economic related benefits were scored among the lowest of the listed benefits. To prosper, the Canadian organic sector must overcome fundamental marketing problems and challenges. Promulgation of the Canada Organic standard may help address some marketing issues by providing more information to consumers. (shrink)

Regional planning for improved agricultural capacity to supply produce, legumes, and whole grains has the potential to improve population health as well as the local food economy. This case study of Waterloo Region (WR), Canada, had two objectives. First, we estimate the quantity of locally grown vegetables, fruits, legumes, and whole grains needed to help meet the Region of Waterloo population’s optimal nutritional requirements currently and in 2026. Secondly, we estimate how much of these healthy food requirements for the WR (...) population could realistically be produced through local agriculture by the year 2026. Results show that a shift of approximately 10% of currently cropped hectares to the production of key nutritious foods would be both agriculturally feasible and nutritionally significant to the growing population. We supplement our findings with some agronomic considerations and community-level strategies that would inform and support such change. The methodology of this study could be applied to other regions: more such analyses would create a broader picture of the diverse qualitative and quantitative agricultural shifts that could synchronize optimal land use with dietary recommendations, thus informing coordinated policy and planning.

Experts identified water quality, manure, good handling practices (including personal hygiene and equipment sanitation), and traceability as critical farm problem areas that, if addressed, are likely to decrease risk associated with microbial contamination of fresh produce from all scales of agriculture. However, the diverse nature of production strategies used by produce farmers presents multiple options for addressing foodborne illness issues while simultaneously creating potential complications. We use a mental models methodology to enhance our understanding of the underlying factors and (...) assumptions of small, medium, and large produce growers that influence their decision-making processes for contamination prevention and control. This empirical evidence demonstrates how challenges and opportunities to food safety are related to the scale of production and marketing strategies. We believe that refining the development of standards and existing extension and outreach food safety programs are important to both consumer protection and supporting agricultural communities. Additionally, this approach will help develop and refine food safety programs that will result in empirically grounded recommendations based on identified grower information needs. (shrink)

Publication date: 15 October 2018 Source: Author: Smiles I. Ume, C.I. Ezeano, R.O. Anozie Role of off-farm income in agricultural production and its environmental effect in Southeast, Nigeria was studied. Two hundred and forty respondents were selected through multi stage random sampling techniques. The objectives of the study were captured using percentage responses, multiple regression and factor analyses. Structured questionnaire was used to collect data from the respondents. The result of socio-economic characteristics of commercial motor cycle riders showed that (...) most riders were youthful, single and experienced. Also, most of the riders used their money generated in the business in hiring labour, procurements of farm inputs, family welfare, expansion of business and procurement of equipment. As well, the menaces caused by motor cycle to the riders and the general society were accidents, traffic jam, crimes, health challenges and gang beating. More so, the determinant factors to the motor cycle riders’ income generated were number of years of experience and marital status. In addition, the effects of motor cycle operations to the environment were dusty and noisy situations, soil erosion, vegetation loss and oil spillage. The avenues in alleviating the affects of motor cycle operations on the environment were use of gadgets, educational programme, ban on the use of big motor cycle, use of traffic control and cleanliness of vehicular emission. The major problems encountered by the riders were extortions by the police, emblem, high cost of fuel and high cost of spare parts. Based on the findings the following recommendations were proffered. There is need to enhance riders’ access to hearing and head protective devices and goggle gadget at affordable prices. Also, experienced and novice riders should be encouraged to remain in business through among others provision of motor cycle parts at affordable prices and rehabilitation of rural roads by the government. Finally, all forms of extortions of the riders should be checkmated and the culprits brought to book. (shrink)

Eating locally continues to be promoted as an alternative to growing concerns related to industrialized, global, corporate agriculture. Buying from local famers and producers is seen as a way to promote a healthier diet, reduce environmental impacts, and sustain communities. The promotion of the local food movement presents the question: is it possible to feed a community primarily from the foods produced locally? We conducted a systematic analysis comparing the United States Department of Agriculture’s (USDA) recommended dietary requirements for the (...) estimated 2008 population with annual local agricultural production for the years 2004–2008 within the counties of the Willamette Valley growing region. Our results indicate that current agricultural production in this highly fertile region does not meet the dietary needs of the local inhabitants for any of the USDA’s six food groups: grains, vegetables, fruits, dairy, meat and beans, and oils. In the most recent year of our analysis, 2008, Willamette Valley agriculture production met 67% of annual required grains, 10% of vegetable needs, 24% of fruits, 59% of dairy, 58% of meat and beans, and 0% of dietary oil requirements. Over the past 5 years there have been significant fluctuations in crop production, particularly in 2006 when grain yields dropped to 29% of needs met. Additionally, many of these commodities are exported as cash crops, thus not contributing to meeting local food needs. We discuss these results as well as areas of potential for increasing production of edible crops for local consumption in the region. (shrink)

Agrifood scholars have long investigated the relationship between farm size and a wide variety of social and ecological outcomes. Yet neither this scholarship nor the extensive research on farmworkers has addressed the relationship between farm size and job quality for hired workers. Moreover, although this question has not been systematically investigated, many advocates, popular food writers, and documentaries appear to have the answer—portraying precarious work as common on large farms and nonexistent on small farms. In this paper, we take on (...) this question by describing and explaining the relationship between farm size and job quality for hired farm workers. To do so, we draw on data from two independently conducted, mixed-methods case studies—organic fruit and vegetable production in California, and dairy farming in Wisconsin—each of which offers a different set of insights into the farm size-job quality relationship. In both cases, larger farms fared better than or no worse than their smaller-scale counterparts for most job quality metrics investigated, though many of the advantages of working on large farms accrue disproportionately to white, U.S.-born workers. We explain that these patterns stem from economies of scale, industrialization, firm size itself, the dominant class identities and aspirations of farmers and their peers, as well as farmers’ and immigrant workers’ fears of immigration enforcement.

Agricultural commercialization as a mechanism to alleviate rural poverty raises concerns about small land-holders, non-adopters, and inequity in the distribution of benefits within transforming economies. Farm gross margins were calculated to assess the economic status and impact of cash cropping on the economic well-being of agrarian households in the Mid-hills of Nepal. On an individual crop basis, tomatoes and potatoes were the most profitable. On a per farm basis, 50 of the households with positive farm gross margins grew at least (...) one vegetable crop, while only 25 of households with negative farm gross margins included vegetable crops in their rotation. Farmers have been hesitant to produce primarily for the market given the rudimentary infrastructure and high variability in prices. Farmers reported selling more crops, but when corrected for inflation, gross revenues declined over time. The costs and benefits of developing markets have been unevenly distributed with small holders unable to capitalize on market opportunities, and wealthier farmers engaging in input intensive cash cropping. Farms growing vegetables had an average gross margin of US$137 per year compared to US$12 per year for farms growing only staple crops. However, the area under production is small, and while vegetable production is likely to continue increasing, sensitivity analysis and scenarios suggest high variability and limited short-term impact on poverty alleviation.

Some models anticipate that liberalized agricultural trade will lead to increased crop diversity, while other models make the opposite claim. These positions were explored in southwestern British Columbia, Canada where, between 1992 and 1998, government subsidies and other measures designed to protect horticultural farmers were lifted, exposing these farmers to foreign competition. Public hearings on the future of agriculture provided an opportunity to tap the knowledge and experience of people affected by this transition. Analysis of transcripts from these hearings, which (...) was confirmed by industry data, shows that trade liberalization has led to the loss of the local fruit and vegetable processing industry. Stakeholders saw the loss as a major factor affecting the choice of crops grown locally. To test this assertion, crop diversity data were analyzed, differentiating crops grown for the processing industry from those grown for the fresh market. Results show that crop diversity increased for processing crops but not for fresh crops. Farmers who used to produce commodities for the fruit and vegetable processing industry seem to have been forced to find new crops to cope with the decline in the processing industry. Here then is a case where the effects of trade were indirect (they were mediated by another variable: the loss of the processing industry) and variable (they differed for the two groups of crops). This may have significant environmental implications as scientific research shows that diverse agro-ecosystems are better able to withstand pest outbreaks and require less agri-chemicals than simple systems.

Because factory-farmed meat production inflicts gratuitous suffering upon animals and wreaks havoc on the environment, there are morally compelling reasons to become vegetarian. Yet industrial plant agriculture causes the death of many field animals, and this leads some to question whether consumers ought to get some of their protein from certain kinds of non factory-farmed meat. Donald Bruckner, for instance, boldly argues that the harm principle implies an obligation to collect and consume roadkill and that strict vegetarianism is thus (...) immoral. But this argument works only if the following claims are true: all humans have access to roadkill, roadkill would go to waste if those who happen upon it don’t themselves consume it, it’s impossible to harvest vegetables without killing animals, the animals who are killed in plant production are all-things-considered harmed by crop farming, and the best arguments for vegetarianism all endorse the harm principle. As I will argue in this paper, each claim is deeply problematic. Consequently, in most cases, humans ought to strictly eat plants and save the roadkill for cats. (shrink)

This paper examines the adoption and application of a participatory approach to the transfer of scientific research to farmers with the objective of supporting government policies for sustainable agriculture. Detailed interviews with scientists and farmers in two case studies in New Zealand are used to identify the potential and constraints of such an approach. One case study involves Māori growers wishing to develop organic vegetable production; the other involves commercial wheat farmers who want to improve their profitability and (...) face major problems of groundwater nutrification. The paper concludes that while both case studies are characterized as successful by those involved, there is an inherent creative tension between the adoption of a participatory approach and its use to advance public policy goals.

This chapter contains sections titled: Notes.

Immigrant farmers from Southeast Asia have brought knowledge of tropical fruit and vegetable production from their home countries to Homestead, Florida. They have developed a new style of farming, one that most closely resembles agricultural systems described as “homegardens.” Although biodiverse agricultural systems are generally thought to be commercially unviable, homegarden farmers successfully manage crop diversity as an economic strategy. By focusing on growing a mixture of specialty Southeast Asian herbs, fruits, and vegetables, the farmers have created their (...) own economic niche and have shielded themselves from the competition of high-volume, single commodity producers. This paper shows that the Homestead homegardens constitute an alternative form of agriculture that is defined by their agroecological and socioeconomic attributes. It also shows that although the homegarden farms are a form of “alternative agriculture,” they do not operate outside of conventional, global systems of agricultural trade; rather the homegarden farms are embedded in global agriculture. The Homestead case problematizes the tendency to delineate between the global and local scales, and alternative and conventional sectors in agriculture today. This paper concludes that the emergence of the Homestead homegardens can only be understood by taking a place-based approach to studying the environment in which the homegardens are situated as well as identifying the large-scale influences on Miami-Dade County.

Abstract : Background: Vegetable agriculture is very important to human continued existence and remains a key driver of many economies worldwide, especially in underdeveloped and developing economies. Objectives: There is an increasing demand for food and cash crops, due to the increasing in world population and the challenges enforced by climate modifications, there is an urgent need to increase plant production while reducing costs. Methods: In this paper, Lemon classification approach is presented with a dataset that contains approximately (...) 2,000 images belong to 3 species at a few developing phases. Convolutional Neural Network (CNN) algorithms, a deep learning technique extensively applied to image recognition was used, for this task. The results: found that CNN-driven lemon classification applications when used in farming automation have the latent to enhance crop harvest and improve output and productivity when designed properly. The trained model achieved an accuracy of 99.48% on a held-out test set, demonstrating the feasibility of this approach. (shrink)

This paper focuses on compost use in overpasses and underpasses for wild animals over roads and other similar linear structures. In this context, good quality of compost may result in faster and more resistant vegetation cover during the year. Inter alia, this can be interpreted also as reduction of damage and saving lives. There are millions of tones of plant residue produced every day worldwide. These represent prospective business for manufacturers of compost additives called “accelerators”. The opinions of the sale (...) representatives’ with regards to other alternatives of biowaste utilization and their own products were reviewed. The robust analyzes of several “accelerated” composts revealed that the quality was generally low. Only two accelerated composts were somewhat similar in quality to the blank sample that was produced according to the traditional procedure. Overlaps between the interests of decision makers on future soil fertility were weighed against the preferences on short-term profit. Possible causes that allowed the boom of these underperforming products and the possible consequences are also discussed. Conclusions regarding the ethical concerns on how to run businesses with products whose profitability depends on weaknesses in the legal system and customer unawareness are to follow. (shrink)

Meat production in South Africa is on an increasing trend. In South Africa rising wealth, urbanisation and a growing middle class means South Africans are eating more processed and high-protein foods, especially meat and dairy products. These foods are more land- and water-intensive than fruit, vegetable and grain crops, and further stress existing resources. Traditional agricultural farms cannot keep up with the increasing demand for animal products and these farms are being replaced with concentrated animal feeding operations. There (...) are a wide variety of problems caused by intensive livestock production. The concerns regarding factory farming in South Africa are social issues affecting food security, health concerns, environmental concerns and ethical concerns. In order to ensure food security in future we need to consider these concerns and support more sustainable systems to produce our food. Animal agriculture, like many other industries, works on the principles of supply and demand. By decreasing the demand for these products, we can decrease their production. Individuals can do this by becoming vegetarian or vegan, but also by simply cutting down one’s consumption of meat, eggs, and milk produced in intensive livestock farms. Less meat would be produced, and there would be less harm to local communities, lower risk of zoonotic disease outbreaks, fewer greenhouse gas emissions, less land degradation and decrease of biodiversity, less damage to our water supplies and fewer animals living lives of suffering in factory farms.

La question des productions agricoles à Délos a fait l'objet d'un intérêt renouvelé ces dernières années : les vestiges d'aménagements agricoles, les fermes et les inscriptions ont été réétudiés. Une des questions en suspens concernait la destination des pressoirs situés dans la ville : produisaient-ils du vin ou de l'huile?
