València — Sustainable Food World Capital. A Social Sciences Vision

The declaration of València as the World Sustainable Food Capital in 2017, based on the market-gardening system of l’Horta — an area girding the city, has put key subjects such as sustainable production and healthy eating on the public agenda. The process leading up to the declaration (which is in part a heritage-based project) has been fraught with contradictions and conflicts stemming from the city’s political, economic and identity dimensions. Examining this process from a Social Sciences angle is of value not only indrawing lessons but also for spawning debating forums in which solutions can be proposed.

Varying Effects of Organic Waste Products on Yields of Market Garden Crops in a 4-Year Field Experiment under Tropical Conditions

Controlling organic and mineral fertilisation is a major concern in tropical environments. An experiment was conducted on an arenosol in the Dakar region, the main market gardening area of Senegal, to evaluate treatments commonly used by farmers. Seven treatments were repeated three times: A mineral fertilisation (MF) treatment based on N-P2O5-K2O (10-10-20), and three organic treatments at two doses (dried sewage sludge (SS), poultry litter (PL) and a digestate from an anaerobic digestion (AD) of cow manures). Each of the organic treatments were supplemented with a normal dose (1) and a double dose (2) of mineral N and K fertiliser. A lettuce, carrot and tomato rotation was grown in four campaigns (2016–2020) on all of the plots. Yields of all three crops in all of the organic treatments were statistically similar (p > 0.05) to the MF in all four campaigns, except for the yield of the lettuce crop under treatment PL-2 in campaigns 2 and 3. The tomato yields were statistically similar under all of the organic treatments in all four campaigns. In contrast, the yields of the lettuce and carrot crops differed statistically from each other and under the different organic treatments in all four campaigns. The yields of all three crops differed in the campaigns with the fertilisation treatment. In each campaign, the yields of each crop were not correlated with the total amounts of N, P and K applied. These differences or similarities in yields are explained by the nature of the organic waste products, the accumulation of nutrients after several applications, the type of crop and interannual differences in temperature.

Assessment of the contamination of Lactuca sativa L. (lettuce) and Lycopersicon esculentum (tomato) by pesticides: Case of market gardeners in Ouagadougou

Background and Aim: The use of pesticides in vegetable production can cause public health problems because these agrochemicals can leave residues in foodstuffs and disrupt the appropriate functioning of the organism. The aim of this study was to assess the level of contamination of lettuce and tomato by pesticide residues. Materials and Methods: This study was conducted from February 12 to May 3, 2021, in concerned five market gardening sites in the city of Ouagadougou. A survey was conducted among 58 market gardeners selected at random from the sites of Boulmiougou, Tanghin No. 1 and 2, Bissigin, and the National School of Public Health. Simultaneously, 25 lettuce samples and 25 tomato samples were collected in a randomized manner for the examination and determination of pesticide residues using the quick, easy, cheap, effective, rugged, and safe method. Results: The market gardening population was predominantly represented by women who had a low level of education. The cultivated species were a mixture of exotic cultures and traditional cultures. These crops were treated with various pesticides, the most common of which belonged to the organochlorine family. The tomato was the crop most contaminated by pesticide residues. However, no active ingredient from the synthetic pyrethroid family was found on lettuce or tomato. Conclusion: Raising the awareness of market gardeners on good practices in the use of pesticides and on alternative methods to synthetic phytosanitary products is of paramount importance for the health of consumers.

Evaluation of the Sustainability of Urban Market Gardens in the City of Meknes (Morocco)

Market gardening constitutes a basis for food security of urban and peri-urban households. However, market gardening is subject to the use of chemical inputs, selected varieties, and genetically modified organisms. These practices are increasingly controversial and are likely to affect the sustainability of vegetable farms. This study assessed the sustainability of 120 randomly selected market garden farms (Meknes) using the surveys and the market garden production sustainability indicator. The results show that the majority of the farms identified are characterized by low sustainability, with the agroecological dimension being the limiting factor. The improvement of the components "Ecological diversity", "Spatial organization", and "Agricultural practices" are the ways to improve the global sustainability of vegetable production in Meknes. The socio-territorial sustainability of production is characterized by a lack of training for producers, a lack of hygiene and safety in production activities, and a low contribution to employment. The economic dimension is characterized by low viability, low economic transmissibility, and financial autonomy. To perpetuate the market gardening in the city of Meknes, it appears necessary to promote ecological intensification, integrated diversification, and promotion of local inputs to the various types of market gardening farms

Parasite load of raw wastewater from the city of Biskra’s discharge outfalls - Z’mor and Biskra valleys (Algeria)

Algeria, like other arid and semi-arid African countries, is confronted by problems related to rapid population growth and water stress (water short-age). This stress fosters raw wastewater reuse in market gardening and hor-ticulture. The advantages of this wastewater consist of their nutrients whose organic materials contribute to soils enrichment with humus, as well as their availability in large quantities. However, raw wastewater reuse entails a po-tential risk of environmental and water resources pollution. The purpose of this work was to evaluate the parasite load of raw wastewater from the city of Biskra’s discharge outfalls (Biskra valley and Z'mor valley), while consider-ing the demographic and socio-economic profile of populations connected to these outfalls. Our results revealed a variety of parasites in the form of hel-minths eggs at the following average concentrations: Ascaris sp. (33.66 eggs/L,), Trichuris sp. (22 eggs/L), Enterobius vermicularis (19.58 eggs/L), Ancy-lostoma sp. (17.41 eggs/L), Nematodirus sp. 17.83 (eggs/L), Hymenolepis nana (21.66 eggs/L), Moniezia expansa (16.5 eggs/L), Taenia sp. (18.5 eggs/L), Fasciola hepatica (0.58 eggs/L) and Strongyloides spp (17.11 eggs/L). The parasitic helminths eggs distribution varies according to the size of urban areas and the socio-economic level of populations connected to each outfall. This study also highlighted the qualitative and quantitative seasonal varia-tions of helminths eggs in wastewater from Biskra’s two outfalls.

Market Gardening as a Livelihood Strategy: a Case Study of Rural-Urban Migrants in Kapit, Sarawak, Malaysia

<p>This research investigates the role market gardening plays in the livelihood strategies of rural-urban migrants. It contributes to the literature on market gardening, livelihood strategies and migration by positioning market gardening as a highly flexible and adaptable mechanism for managing the rural-urban transition among households with few labour alternatives. Such perspective elevates market gardening from simply being a land use category to being an active instrument in the management of rural-urban migration processes. The expanding urban centre of Kapit, Sarawak, Malaysia is used as a case study of a rapidly expanding small town in a predominantly rural domain. Market gardening emerges as an important source of income for both individuals and households as rural-urban migrants negotiate the transition between farming and urban settlement. Many rural-urban migrants adopt market gardening or associated market selling as their first employment in urban centres. First generation migrants often have low off-farm skills which limit their ability to take on alternative occupations. While a rise in market gardening activity is enabled by a growth in demand for fresh vegetables, in the context of Sarawak it is also heavily influenced by the involvement of the state that actively encourages participation, provides advice to farmers and offers subsidies. The expansion of roads from rural to urban areas also plays an important role in improving market gardeners access to urban markets, as well as their access to material inputs. At the same time, increased access has heightened competition by attracting new entrants to urban vegetable markets. Interviews with 10 sellers and 30 market gardeners from Kapit were conducted in 2004. In contrast to market gardening in larger centres documented in the literature, this small isolated town case identifies market gardeners as typically middle-aged, rural-urban migrant women with limited education and employment skills other than subsistence farming. Market gardening and associated selling is adopted because they are unable to acquire alternative employment to support their household and children’s education. As such, market gardening in the urban setting is a logical extension of the woman’s role as the primary farmer in rural areas.</p>

Pesticides used on the cultivation of Brassica oleracae var capitata L. (cabbage) in the Niayes area (Senegal): Impact on the environment and the health of producers

The Niayes area, by its climate and its morpho-pedology, is a favorite area for market gardening in Senegal. For vegetables, it is accredited to more than 60% of harvests. Among the cultivated speculations is the cabbage (Brassica oleracae var capitata L.). With a view to alleviating the negative effect of pests, a variety of pesticides are used by producers. This study was undertaken with a view to contribute to a better knowledge of the pesticides used in the production of Cabbage (Brassica Oleracea) in the Niayes. Specifically, it aims to characterize the pesticides used in the area and to determine their impacts on the environment and the health of producers. To carry out this study, a survey was carried out among 163 cabbage producers in the Niayes area (Mboro and Diogo) from February 06 to March 03, 2018. The data entry and processing of the results were made thanks to the Epi info software and Excel spreadsheet. The results showed that 87.1% of producers use chemicals. At the end of this study, 24 active ingredients, mainly comprising four (4) major chemical families, were identified. The most widely used pesticides are insecticides, insecticides-acaricides-nematicides and herbicides with respectively 56%, 12% and 11% of citations. Profenofos is the most cited active ingredient with 21.1% followed by emamectin benzoate with 14%, pendiimathalin (12%) and carbofuran (11%). In addition, Organophosphates and Amino-Phosphates are the most representative chemical families with 48% and 15% citations, respectively. Among the producers; 85.9% have already suffered from poisoning from the use of pesticides. 43% of producers reported the death of insects and other animals as a result of the treatments.

Vegetable Growers and Women Empowerment: Their Effect in Poverty Reduction in Region Korhogo (Côte d’Ivoire)

In C&ocirc;te d&rsquo;Ivoire, women occupy an important place in the agricultural sector, which is the basis of the country&rsquo;s economy. There is unanimous agreement on the essential role that these women must play through their empowerment for the country&rsquo;s development. Therefore, we must find appropriate solutions to the problem of women&rsquo;s empowerment in order to enable them to participate vigorously in the country&rsquo;s development. This study aims to address the problems of women&rsquo;s empowerment in agriculture by highlighting the potential opportunity that the practice of market gardening represents for women&rsquo;s empowerment. Based on a qualitative approach using ENV (2019) data, the Women&rsquo;s Empowerment in Agriculture Index (WEAI) shows that women producer of market garden produce are as self-reliant as their counterparts in other agricultural sub-sectors. In the same logic, the WEAI shows us that the practice of this crop has a positive effect on women&rsquo;s empowerment. By using these four (4) methods of effect determination, namely the Nearest Neighbour Method, Radius Method, Stratification Method and Kernel Method, the following values were obtained: 0.007; 0.039; 0.017; 0.027, which are all positive. The objective of the study is to determine the impact of market gardening on the empowerment of the women who practice it.
