Résumé :

Indigenous Leafy Vegetables foods have an exceptional place in African cuisine. It is commonly argued that vegetable consumption reflects cultural backgrounds and their value transcends a biological one, as food, to symbolism enhancing the functioning of society and promoting social order. This study set to determine species use, folkloric dimensions and taste preferences in a rural East African setting. A bio-cultural approach reinforced by ethno-botanical tools conducted over a three-year period and recourse to a corpus of Luo ethnic food plant literature and gathering of folklore elements from a conversational context was used to study socio-cultural elements of vegetables foods of people in Migori and Suba districts of Kenya. Seventy-four respondents, 56 female and 18 males, of mean age 43years and ranging between 16 and 84 years participated in focus group discussions and research interviews. Herbarium specimens of 34 leafy edible plant species in seventeen plant families are deposited at the University of Nairobi and the Catholic University of Eastern Africa herbaria. This study documents 17 sayings (folkloristic products) of different genre: mantras, traditional beliefs, customs, practices, folk stories/ tales, songs, jokes and lexical phrases. Their sociolinguistic analysis reveals they address issues appropriate to Luo ritual, social status, nutrition, taste preferences, cooking habits and conflict resolution. Though Luo folklore indicates aversion for bitter vegetables, the body of folkloric wisdom sustains vegetable dish consumption. The preference and craving for bitter tasting herbs by elder women was because of an understanding of both food and medicinal values. This paper concludes that vegetable consumption reflects cultural backgrounds and experiences. Folklore defines how Africans perceive, define, and value indigenous Leafy Vegetables in their own terms and presents a stable platform for cultural analysis of oral food culture. Indigenous Leafy Vegetables are symbolic "sources of illumination" that orient African people persistently with the system of meaning in their culture.

Résumé :

The increased awareness of the health protecting properties of non-nutrient bio-active compounds found in fruits and vegetables, has directed immense attention to vegetables as vital components of daily diets. For sub-Saharan African (SSA) populations, this attention on vegetables as vital dietary component s is significant, as leafy vegetables have long been known to be indispensable ingredients in traditional sauces that accompany carbohydrate staples. African indigenous and traditional leafy vegetables thus have a pivotal role in the success of the World Health Organization’s (WHO) global initiative on fruits and vegetables consumption in the sub-continent. The joint WHO/FAO 2004 report on a Global Strategy on Diet, Physical Activity and Health, recommended a minimum daily intake of 400g of fruits and vegetables. Also, at their 2004 joint Kobe workshop, the WHO and FAO developed a framework that proposes ways to promote increased production, availability and access, and adequate consumption of fruits and vegetables. This framework is expected to guide the development of cost-efficient and effective interventions for the promotion of adequate consumption of fruits and vegetables at the national and sub-national level. This paper explores ways to integrate African indigenous leafy vegetables into the global fruit and vegetable programme initiative, and identifies some existing barriers to their effective mobilization. African Leafy Vegetables are increasingly recognized as possible contributors of both micronutrients and bio-active compounds to the diets of populations in Africa. Available data on the more commonly consumed varieties point to antioxidants containing leafy vegetables that can also provide significant amounts of beta carotene, iron, calcium and zinc to daily diets. How can the successful Nairobi leafy vegetable experience, be mainstreamed across the sub- continent to ensure their mobilization and integration in WHO’s fruit and vegetable initiative? The Kobe framework recommends that fruit and vegetable promotion interventions should consider the process from production to consumption. Very little is known about the production and consumption of African Leafy Vegetables. An expert report on patterns of vegetable consumption in the sub- continent lists common vegetables as onions , carrots, tomatoes and cabbage. Clearly, information on production, processing, distribution and marketing, preparation and consumption of vegetable species relevant to SSA, are vital and constitute the prop on which intervention programmes can be developed. Through its long collaboration with national governments, Bioversity International is well placed to catalyze the process of data generation and dissemination by countries in the sub-continent.

Résumé :

The nutritional and cultural importance of African Leafy Vegetables has become very important in South Africa in the past few years. Recent research has also confirmed these issues, leading to the incorporation of African Vegetables into the core business of the ARC. ARC -Roodepl aat wants to improve the distribution and conservation status of African Leafy Vegetables. Geographical collection data on Amarant, Cleome gynandra, Corchorus olitorius and Vigna inguiculata was obtained from the National Botanical Institute and the data w as analyzed with DIVA and Flora map. Ecogeographical distribution maps were drawn to predict the possible distribution of the species. Germplasm of African Leafy Vegetables was collected during routine visits and the conservation status was discussed with participants in the study areas of Arthurstone in Bushbuckridge, Watershed near Ladysmith and Mars/Glenroy near Polokwane. Germplasm of various species were also collected in collaboration with the Plant Genetic Resource Centre (NPGRC) of the Department of Agriculture in Arthurstone and Watershed. The NPGRC included leafy vegetables in their mandate since this trip. Seed flow diagrams were used to discuss the Watershed com munity’s seed exchange systems. It was clear when discussing African leafy vegetable s in communities that their conservation and utilization are declining. Also looking at the trendlines of African Vegetables availability and utilization it is clear that the use and availability of African Leafy vegetables are declining due to various rea sons. Two major reasons are the negative image of the African Leafy Vegetables and the increased use of “exotic” vegetables like spinach and carrots. The active promotion, use and conservation of African Leafy Vegetables are important if we want to increase the production potential and potential contribution towards food security in South Africa. This will ensure that the status of these crops is enhanced, specifically their contributing towards sustainable nutrition as well as sustainable production. Resul ts from promotion activities in the project (reported in another paper) indicated that the negative image of African Leafy Vegetables could be reversed and also had an affect on the roll -out of the project to other areas of research such as plant protection, nutritional analysis and food safety, crop science and indigenous knowledge systems.

Résumé :

Indigenous African leafy vegetables have recently been attracting research attention not only in terms of their inherent nutrition quality but also the healing power of some of these plants. Diversification of diets through increased utilization and consumption of these vegetables would go along way in alleviating hidden hunger and malnutrition. The main objective of this survey was to determine the consumption patterns and medicinal use of indigenous African leafy vegetables by the residents of urban and peri -urban Nairobi. A descriptive cross -sectional survey was conducted and the survey subjects included populations from all socio -economic strata and income levels. Probability proportional to size stratified sampling was used to select a representative sample of 800 households (600 urban and 200 peri -urban). Data were collected through structured questionnaires, focus group discussions and an observation checklist guide. A picture guide consisting of all foods available on the Nairobi markets was prepared, and used by the researchers to help the respondents to identify the vegetables they consumed. Ethnic origin was found to greatly influence consumption of indigenous African leafy vegetables. There was no significant relationship between household income and education level and choice or use of indigenous leafy vegetables. Some of the reasons for not consuming the vegetables included prohibitive costs and not knowing how to cook them especially those from other tribes. More than 60 percent of the respondents reported that the vegetables had a medicinal value attached to it and some were said to cure more than one disease. About half of those who used them also said the vegetables were healthy. It was concluded that dietary diversity of indigenous African leafy vegetables in addition to providing essential nutrients presumably offers broad benefits to health. The findings support interventions to promote use of indigenous African leafy vegetables as a food - based initiative towards alleviation of micronutrient deficiencies and poverty through premium value addition incentive strategies.

Résumé :

High poverty levels in western Kenya that are manifested in malnutrition and poor health prevail yet the region is endowed with high agricultural biodiversity like African Leafy Vegetables (ALVs). The vegetables have high micronutrient content, medicinal properties, several agronomic advantages and economic value yet their potential in alleviating poverty and ensuring household food and nutrition security in the rural areas has not been exploited. Despite all the above advantages, these vegetables have been neglected and face several constraints hampering optimal production such that if the situation is left unchecked it may result in loss of this biodiversity. It is because of this that a study was conducted with the objectives of documenting the diversity of African Leafy Vegetables and to collect indigenous knowledge on production, agronomic and cultural practices in three communities of Western Kenya. A survey was conducted between January 2002 and March, 2003, in six districts in Western and Nyanza provinces representing the Luhya, Luo and Kisii communities. A structured questionnaire was administered to eighty purposively sampled respondents distributed in the ratio of 30:20:30 for Luhya, Luo and Kisii communities respectively. One focus group discussions per community was held and two key informants per community were interviewed. Over 90% of the respondents indicated that there was an increase in the cultivation of African Leafy Vegetables. Ten African Leafy Vegetables were found in the three communities representing eight botanic families. All the communities cultivated the ALVs at a subsistence level in home gardens, with organic sources of manure and under an intercrop system. Broadcasting was practiced by 20%, 40% and 60% of the respondents from the Luhya, Luo and Kisii communities respectively. Harvesting was done by first uprooting at thinning then ratooning. The major constraints facing production of African Leafy Vegetables included lack of quality seed, pests and diseases, drought, poor marketing strategies and lack of technical packages. In conclusion, the study showed that all the three communities studied had a high diversity of cultivated African Leafy Vegetables covering eight botanic families; respondents in all the communities cultivate African leafy vegetable in a subsistence, home gardening, intercrop system where the use of chemical fertilizers and chemicals was minimal and the major constraints of production of African Leafy Vegetables included, poor quality seed, drought and poor marketing systems and infrastructure. The identified species should be promoted and improved as commercial crops.

Résumé :

A survey was carried out to document the diversity and immune boosting claims of African indigenous leafy vegetables (AILVs) in Western Kenya. Both qualitative and quantitative methods of data collection were used. The results showed that there is diversity of AILVs in the study area with nine popular and frequently consumed, but cassava leaves, stinging nettle and russian comfry are not popular. Seven of these are cultivated but two, stinging nettle (Urtica massaica) and vine spinach (Basella alba) grow wildly. The AILVs are cultivated at subsistence level on home gardens with minimal inputs and only excess of this is sold. The religion one belonged to was significant (p<0.05) in determining consumption or not of some of the vegetables. The vegetables are rain fed and the process of harvesting is by first uprooting during thinning followed by breaking the main stem and finally plucking off the leaves with maturity. Vegetable preparation in most households was mainly by women. The elderly women were keen in this process and spent more time in preparing the vegetables which were believed to be ‘nutritious’. There was no processing and preservation of the AILVs for use during the dry season. The communities rely on wild weeds during such seasons. The AILVs though consumed for good nutrition are also associated with various medicinal and immune boosting claims. Out of the nine, five are known for various health benefits, African nightshade and spider plant for good nutrition by 31.8% and 25.1% of the respondents, respectively, slender leaf for healing power by 34%, cowpea leaves and slender leaf for anti-aging by 50% and 43.8%, respectively, and cowpea leaves (43.6%) and amaranthus (53%) for smooth skin and adding blood, respectively. Chi square analysis indicated that African night shade, spider plant and amaranthus are statistically significant (p<0.05) in contributing to good nutrition, healthy functioning of the body and immune boosting. Further analysis showed that spider plant and amaranthus are significant (p<0.05) for immune boosting.

Résumé :

Leafy vegetables are important sources of provitamin A carotenoids. Information on their ability to provide vitamin A is often misleading because of the methodology used to assess bioefficacy. Mongolian gerbils were used to evaluate the bioefficacy of provitamin A carotenoids in tropical leafy vegetables (i.e. Solanum nigrum, Moringa oleifera, Vernonia calvoana and Hibiscus cannabinus) that are indigenous to Africa. Gerbils (n 67) were vitamin A-depleted for 5 weeks. After a baseline kill (n 7), the gerbils were weight-matched and assigned to six treatment groups (n 10; four vegetable groups; negative and positive controls). For 4 weeks, the treatments included 35 nmol vitamin A (theoretical concentrations based on 100 % bioefficacy) in the form of vegetables or retinyl acetate. In addition to their diets, the control and vegetable groups received daily doses of oil, while the vitamin A group received retinyl acetate in oil matched to prior day intake. Serum and livers were analysed for vitamin A using HPLC. Serum retinol concentrations did not differ among groups, but total liver vitamin A of the vitamin A and vegetable groups were higher than that of the negative control group (P < 0·0001). Liver β-carotene 15,15′-monooxygenase-1 expression levels were determined for two vegetable groups and were similar to the positive and negative controls. Conversion factors for the different leafy vegetables were between 1·9 and 2·3 μg β-carotene equivalents to 1 μg retinol. Small quantities of these vegetables maintained vitamin A status in gerbils through efficient bioconversion of β-carotene to retinol.

Résumé :

Thesis (MSc. (Agricultural Economics)) -- University of Limpopo, 2014
There are few plant species commercialised significantly globally and food requirements are mainly met by only few species. However, there is an enormous number of under-utilised species that play a vital role in the livelihood of rural households. These species are referred to as indigenous crops. Indigenous crops are adaptable to local agro-ecological conditions even where there is unreliable rainfall, which is the case in many parts of the country, require a minimum production management, mature early, and are easy to harvest and preserve and require less capital investments. Despite all these, in South Africa indigenous leafy vegetables (ILVs) were not commercialised and most researchers did not pay much attention to do research on possibilities of commercialising these crops. Thus this study investigated the economic potential of commercialising indigenous leafy vegetables in the rural South African context in general and in the study area in particular. The objectives of the study were (1) to identify the socio-economic characteristics of ILVs producers in rural areas of Capricorn district, (2), to investigate constraints faced by farmers in commercialising ILVs in rural areas of Capricorn district, (3), to determine the productivity of indigenous leafy vegetables in rural areas of Capricorn district, and (4), to assess different types of marketing channels of ILVs in rural areas of Capricorn district. The study used Stochastic Frontier Production Function to determine the productivity and to assess the socio-economic characteristics of producers of Indigenous Leafy Vegetables. Bubble chart was used to assess the marketing channels whilst consumer data was captured into a statistical package. The results indicated that there are several significant socio-economic factors that affect ILV production and there are also factors which constraint farmers from commercialising ILVs. Productivity of ILVs in the study area varied a lot among farmers; some farmers had a high productivity but most farmers had a low productivity. The results indicated that out of the factors included in the analysis significant production factors were; amount of labour used, cost of hiring tractor service and land devoted to ILVs and inefficiency factors were; gender, age, household size, farming experience, farm size, v hired labour, primary occupation and land ownership. ILV farmers had no formal marketing channels; they sold their product direct to consumers or through hawkers. Therefore, the study recommends the integration of science/modern technology and indigenous knowledge, to improve the productivity of ILVs. Since farmers were not technically efficient, therefore it is important to run workshops that will help them improve their production and marketing skills and how to market their products. Or create booklets that have information on how to efficiently produce ILVs. There should also be awareness campaign on the benefit of ILVs in both rural and urban communities. The study also recommends a multi-disciplinary approach in developing the crop; more stakeholders should be involved so as to make the crop appealing. Finally the study recommends the commercialisation of these crops due to the fact that they have the potential and are demanded in most parts of South Africa.

Résumé :

This study used cross-sectional survey data to estimate farmers` perceptions of, and commonly cultivated ILVs, factors that influence the participation of smallholder famers in the production of Indigenous Leafy Vegetables and its contribution to household food security]. With regard to farmers` perceptions of ILVs, descriptive results reveal that a majority of the people from the study area share positive perceptions with respect to ILVs. Regression estimates for determinants of participation indicate that the production of ILVs is primarily conditioned by shared perceptions and institutional factors rather than the socio-economic attributes of farmers. Public policies that address the institutional framework (extension, credit, market and social networks) in favour of ILVs are more likely to promote production. Also, more research on the documentation and benefits of ILVs, supported by investments targeting educational campaigns towards promoting positive attitudes and dispelling fears and myths surrounding ILVs, will further promote production. With reference to the contribution of ILVs to food security, descriptive results indicate that participation in the production of ILVs leads to a higher HDDS and a lower HFIAS. Regression estimates further revealed that participation positively contributes to a higher HDDS and a lower HFIAS, suggesting that households who participate in the production of ILVs are more likely to be food secure than non-participants. Therefore, participation in the production of ILVs has significant potential to address household food security.

Résumé :

Le verdure a foglia indigene africane (AILV) fanno parte della flora del sub-Sahara e sono in grado di prosperare in condizioni di scarsità di acqua e nutrienti. Le AILV rappresentano una preziosa fonte di nutrimento, in quanto ricche di fibre, vitamine e sali minerali. Dalla coltivazione al consumo, diverse specie di microorganismi interagiscono con le AILV. I microrganismi del suolo e della fillosfera delle AILV possono influire sulla salute delle piante e del consumatore. I parametri della diversità microbica e la relativa attività enzimatica sono strettamente correlati alla fertilità del suolo. Mentre, la presenza di microrganismi contaminanti e potenzialmente patogeni nella fillosfera riduce la durata di conservazione della verdura. In questa tesi, è stata quindi delineata l'interazione tra AILV e microrganismi. La coltivazione delle AILV è risultata legata a cambiamenti nelle comunità microbiche del suolo e all'aumento delle attività enzimatiche. Inoltre, la modulazione del microbiota della fillosfera utilizzando sale e saccarosio ha innescato la proliferazione di batteri acido-lattici e fermentatori e ha limitato la proliferazione dei microrganismi di deterioramento. I risultati hanno quindi dimostrato che la coltivazione delle AILVs potrebbe limitare l'erosione del suolo se avviene seguendo buone pratiche agricole. Inoltre, la crescita dei batteri di deterioramento può venire ostacolata utilizzando la fermentazione naturale che coinvolge strumenti poco costosi e conservanti accessibili. Perciò le AILV hanno un ruolo importante nel mantenimento della biodiversità e la popolazione sub-sahariana potrebbe giovare dalla loro conservazione prolungata, in quanto fonte di nutrienti importanti.
African indigenous leafy vegetables (AILVs) are part of the sub-Saharan flora, thriving in water and nutrient scarcity. Moreover, AILVs are rich in macro- and micro-nutrients, representing a precious source of nourishment. From cultivation to consumption, microorganisms interact with AILVs, sorting different effects. AILVs’ soil and phyllosphere microorganisms can have an impact on plants and consumers’ health. Soil fertility is strictly correlated to microbial diversity and enzymatic activity. While, the presence of spoilage and potentially pathogenic microorganisms in the phyllosphere reduces the shelf-life of the commodity. In this thesis, the interaction between AILVs and microorganisms has been outlined. AILVs cultivation resulted linked to shifts in soil microbial communities and increased enzymatic activities. Moreover, the modulation of phyllosphere microbiota using salt and sucrose triggered the proliferation of lactic acid fermenting bacteria that curbed the proliferation of spoilage microorganisms. The outcomes thus underlined how AILVs cultivation coupled with good agricultural practices could limit soil erosion. Secondly, the growth of spoilage bacteria can be hindered using natural fermentation that involves inexpensive tools and affordable preservatives. Hence, AILVs have an important role in maintaining biodiversity and their preservation can ensure a nutrient food source for the sub-Saharan population.

Résumé :

AIM AND OBJECTIVES The main aim of this thesis was to explore the possibilities of promoting the cultivation, utilisation and consumption of indigenous and traditional plant foods (ITPF) among urban and rural communities in the North West Province of South Africa that could possibly lead to increased IK and dietary diversity. The objectives were the following: Assess consumption of TLV in the rural and urban communities. Compare nutritional status of consumers and non-consumers of TLV using data obtained from the Prospective Urban and Rural Epidemiology (PURE-SA) study. Assess the availability, cultivation and consumption patterns of ITPF. Assess indigenous knowledge (IK) within the rural and urban communities. Assess consumers’ views of ITPF in the rural and urban communities. Assess consumers’ acceptance of, preference for and consumption intent of dishes made from cowpea leaves. To compile recipes for the most important ITPF commonly consumed in the study areas in order to promote the cultivation and consumption of ITPF (see Addendum D). STUDY DESIGN Health profile study: For the health profile study, a comparative study was conducted on the baseline data of the population that participated in the PURE-SA study (1004 urban and 1006 rural participants) which follows the health transition in urban and rural subjects over a 12 year period. The baseline data for the North West Province of South Africa were collected from October to December 2005. Utilisation of ITPF study: The study on the utilisation of ITPF used a sequential explanatory study design which involved the collection of quantitative and qualitative data and analyses. The consumer acceptance study consisted of an explorative and experimental phase. Participants were male and female, aged older than 20, residing in the selected communities and knowledgeable on the indigenous and traditional foods of the area. METHODS A variety of quantitative and qualitative research techniques were used. Data were generated through questionnaires, focus groups and individual - and group interviews. Health profile study: Demographic characteristics and frequency of consumption of TLV data were collected by the researcher from 396 randomly selected subjects from participating subjects in the PURE-SA study. An extensive nutritional profile of these subjects was compiled including blood samples, blood pressure, anthropometric measurements and total dietary intake by means of a quantitative food frequency questionnaire. Utilisation of ITPF study: A comparative study was conducted in rural and urban populations of the North West Province. Data were collected by the researcher using a questionnaire (n=396 households), key informant interviews (n=4), and four focus groups. Consumer study: Four focus groups were conducted by the researcher, two in rural and two in urban communities, to investigate consumers’ views about ITPF. Eighty-seven participants were recruited based on a specific purpose rather than randomly. Consumers’ acceptance of, preference for and intended consumption of products made with cowpea leaves were assessed. A 5-point hedonic scale and a 7-point food action rating scale were used for sensory evaluation. RESULTS Health profile study: As expected, rural inhabitants were more likely to consume TLV. However, no household reported to consume TLV more than ten times a month. Factors such as price (affordability) and availability and easy-to-get-to points of purchase were found to be major constraints in the consumption of TLV, especially in urban communities. Urban respondents had significantly higher macronutrient intakes than rural subjects. There was no significant difference between the selected micronutrient intakes between consumers and non-consumers of TLV. Non-consumers of TLV had higher blood lipid levels than consumers from both the rural and urban areas. In the urban subjects the relative risk to develop high blood pressure was higher in non-consumers of TLV than in the consumers. However, the risk ratios of raised serum cholesterol and triglycerides were not significantly different. Utilisation of ITPF study: More plant foods were available and consumed in the rural area than the urban area. However, fewer species were available than expected due to insufficient rainfall, poor soil quality, deforestation and over harvesting. Consumption of indigenous foods was influenced by price, culture, seasonality/availability, accessibility and diversity in markets. A lack of markets for indigenous crops, insufficient rainfall and diseases and pests were cited as the major cultivation problems, followed by a lack of capital to buy farming implements, veld fires and poor soil quality. Consumer study: Based on the qualitative focus group discussions, factors that influence the consumption of ITPF were identified. These factors included benefits and barriers of ITPF consumption. Ways to increase ITFP consumption were also identified. Health and nutrition; tradition and culture; and food safety emerged as drivers for ITPF consumption. A lack of knowledge and skills of food preparation and negative images and unfamiliarity of ITPF acted as barriers. Differences in views existed between older and younger consumers. In general younger consumers found ITF rather revolting and undesirable, humiliating to consume. Sensory evaluation of food samples for the pooled data of the total study population showed that significant differences existed between the acceptability of all attributes, overall acceptance and consumption intent. Socio-demographic backgrounds such as place of residence (urban or rural), levels of education and age were shown to influence the acceptability of food samples and consumption intent. There was no positive association between acceptability of food and gender. CONCLUSIONS Health profile study: This study showed the possibility of beneficial effects of rural diets, however, the lack of knowledge concerning the bioavailability of nutrients from TLV and lack of information on food consumption database, of these vegetables constitute main barriers to obtaining information on nutrient intake. The low frequency of consumption of TLV is of concern. Taking into consideration safe agricultural practices, the promotion of TLV might be a solution towards healthier diets and combating poverty. More research is needed to investigate the health effects of these vegetables. Utilisation of ITPF study: It is evident that there was a limited number of ITPF species cultivated and consumed. Consumers, especially older people, were found to possess extensive knowledge regarding the availability of ITPF species, their habitat and uses, seasonality and potential health benefits. There is a need to intensify education on conservation of natural resources and more studies should be undertaken to document and disseminate traditional food systems. In addition, there is a need to integrate existing health and nutrition interventions with traditional food promotion. Consumer study: The results highlighted the importance of making use of a mixed method approach which made it possible not only to identify factors that influence the consumption of ITPF but also to understand the dynamics thereof from focus group discussions and how they influence acceptability, preference and consumption intent. Important benefits (drivers) of and barriers to ITPF consumption as well as suggestions on how to increase ITPF consumption were identified. Barriers to ITPF consumption and low scores of acceptability provided by younger participants can be connected to misconceptions about ITPF and lack of familiarity with the products. Therefore, a combination of strategies aimed at enhancing individual awareness of the health benefits of ITPF, decreasing barriers and conducting more acceptability studies may have a positive impact on the younger segment of the population.

Résumé :

In this article the term ‘African leafy vegetables’ was adopted to refer to the collective of plant species which are used as leafy vegetables and which are referred to as morogo or imifino by African people in South Africa. Function is central in this indigenous concept, which is subject to spatial and temporal variability in terms of plant species that are included as a result of diversity in ecology, culinary repertoire and change over time. As a result, the concept embraces indigenous, indigenised and recently introduced leafy vegetable species but this article is concerned mainly with the indigenous and indigenised species. In South Africa, the collection of these two types of leafy vegetables from the wild, or from cultivated fields where some of them grow as weeds, has a long history that has been intimately linked to women and their traditional livelihood tasks. Among poor people in remote rural areas the use of these types of leafy vegetables is still common but nationwide there is evidence of decline, particularly in urban areas. Cultivation of indigenous or indigenised leafy vegetables is restricted to a narrow group of primarily indigenised species in South Africa. Seven groups of indigenous or indigenised African leafy vegetables that are important in South Africa were given special attention and their local nomenclature, ecology, use and cultivation are discussed.

Résumé :

African leafy vegetables (ALVs) are a diverse set of crops grown across sub-Saharan Africa. They have been a staple of traditional diets and contain many critical micronutrients but their importance has been largely ignored by researchers and policymakers at the expense of imported crops. Availability, accessibility, and utilization of ALVs are limited by factors across the supply chain. This research investigated seed systems, drought tolerance, hydroponic production, market barriers, consumer preference, and the impact of gender as related to ALVs. We found that ALVs play an important role in food security and that critical differences exist between formal and informal sectors. Women play a stronger role in informal sectors, but the balance between the formal and informal markets is changing, and this may jeopardize the incomes of many women. The determinants of household security were different for male- and female-headed households, and this information can be used to address the gap in food security between genders. Market barriers differed for formal and informal ALV retailers but consumer preference for quality did not, suggesting that investment in postharvest handling may allow ALV growers to capture greater value. We also showed that ALV germplasm is diverse, offering both a wide range of species with different agronomic characteristics and important differences in drought tolerance among accessions. Crop- and location-specific factors impacted farmer adoption of seeds and technologies, highlighting the importance of evaluating policies and interventions with sensitivity to gender, species, and location. ALVs can be used to empower marginalized populations, and this research proposes several ways to do so. However, the market for ALVs is changing rapidly, and future research is needed to monitor trends and assure that these vegetables are used to increase social equality rather than aggravate existing disparities. Promoting savings groups and capital accessibility can help to build this capacity, especially for women. Overall, this research revealed that a wide diversity of under-studied ALV species is contributing to food security in important ways and that the potential exists to strengthen production, distribution chains, and markets further. Well-targeted research and investment could have a substantial impact in this area in improving sustainability and food security for people across sub-Saharan Africa.

Résumé :

Concern regarding the decline in the knowledge and use of indigenous green vegetables exists in many southern African regions including Swaziland. Reasons for this are, amongst others, attributed to a lack of inter-generational knowledge transfer, the influence of westernisation and changing food values and attitudes, as people nowadays regard indigenous green leafy vegetables as a low status food. It is imperative that knowledge of these foods be documented before it is lost to future generation. Indigenous green leafy vegetables have long been considered healthier options than the many recently introduced western-orientated foods, which are closely linked to chronic lifestyle diseases. The aim of this study was to determine, describe and compare the knowledge of indigenous green leafy vegetables among two generations of rural Swazi women from the Eluyengweni community, and how it manifests in their food practices. Studies on indigenous green leafy vegetables in Swaziland are limited. This study will fill the knowledge gap in this field. The human ecological perspective was adopted as theoretical perspective and an explorative mixed method approach was followed. Qualitative data was collected through focus group discussions with younger (25-45 years) and older (over 45 years) women. Face-to-face structured interviews provided quantitative data on the knowledge the women had of indigenous green leafy vegetables, including their procurement, preparation, preservation and consumption patterns. The convenience sample comprised 102 respondents. Observation was done concurrently during both phases of data collection and photographs accompanied comprehensive field notes. It transpired that the availability of indigenous green leafy vegetables had declined in the community and those that were available were not easily accessible as they were located on the outskirts of the community. In spite of changes in the physical and natural environment, some indigenous green leafy vegetable species are still available in summer. It is clear that the older women, in comparison to their younger counterparts, had more knowledge of indigenous green leafy vegetables in terms of identifying them, where they are found and how they are used. Familiar and available indigenous green leafy vegetables such as imbuya (Amaranthus), chuchuza (Bidens pilosa) were preferred, and consumed fairly regularly. Although indigenous green leafy vegetables were still part of the food practices in this community, their consumption among the younger generation had declined. However, due to factors related to modernisation, economic influences and technological advancement the majority of both the younger and older participants seem to have become dependent on, and often include, western-orientated food in their food consumption patterns. Based on the results, recommendations are made to capture and preserve the knowledge of indigenous green leafy vegetables in this community and to revive interest in these vegetables and promote their consumption.
Daar is 'n besorgdheid oor die afname in kennis in die gebruik van inheemse groen blaargroentes in baie streke in Suider Afrika, insluitend Swaziland. Redes wat hiervoor aangevoer word, is onder andere, die gebrekkige oordrag van kennis van een geslag na die volgende, die invloed van verwestering asook 'n verandering in waardes en houdings aangesien mense inheemse groen blaargroentes deesdae as 'n lae status voedsel beskou. Daarom is dit noodsaaklik dat kennis oor hierdie voedsel gedokumenteer word voordat dit verlore gaan vir die nageslag. Inheemse groen blaargroentes word gesonder geag in vergelyking met Westers-georienteerde voedsel, wat op hul beurt nou geassosieer word met kroniese lewenstyl siektes. Die doel van hierdie studie was om die kennis van inheemse groen blaargroentes van twee geslagte landelike Swazi vroue van die Eluyengweni gemeenskap te bepaal, beskryf en te vergelyk asook hoe dit manifesteer in hul voedselpraktyke. Studies oor inheemse groen blaargroentes in Swaziland is beperk en hierdie studie dra by om die leemte in kennis in hierdie studieveld te vul. Die menslike ekologiese perspektief is a teoretiese perspektief gebruik en 'n verkennende gemengde metodologie is as navorsingsbenadering gevolg. Kwalitatiewe data is deur middle van fokusgroep gesprekke met beide die jonger (25-45 jaar) en ouer (ouer as 45 jaar) vroue ingesamel. Met behulp van gestruktureerde individuele onderhoude is kwantitatiewe data oor die kennis van inheemse groen blaargroentes ingesamel wat die verkryging, voorbereiding, preservering en verbruikspatrone van hierdie groentes ingesluit het. 'n Geriefssteekproef van 102 respondente het aan die studie deelgeneem. Waarnemings is gedurende beide fases van die data insameling uitgevoer en fotos en volledige veldnotas is ingesluit. Dit is duidelik dat die beskikbaarheid van inheemse groen blaargroentes in hierdie gemeenskap afgeneem het, en dit wat beskikbaar was, was nie maklik toeganklik nie, omdat dit aan die buitewyke van die gemeenskap gelëe was. Ten spyte van die verandering in die fisiese en natuurlike omgewing is sommige inheemse groen blaargroentes steeds beskikbaar gedurende die somer. Dit is duidelik dat die ouer vroue, in vergelyking met die die jonger vroue oor meer kennis van inheemse groen blaargroentes beskik het met betrekking tot die identifisering, waar hulle groei en hoe om hulle te gebruik. Bekende en beskikbare inheemse groen blaargroentes soos gewone misbredie (Amaranthus) en knapsakkerwel (Bidens pilosa) was voorkeur groente en is redelik gereeld gebruik. Alhoewel inheemse groen blaargroentes steeds deel vorm van die voedselpraktyke in hierdie gemeenskap, het die gebruik daarvan deur die jonger geslag afgeneem. As gevolg van faktore soos modernisering, die ekonomie en tegnologiese vooruitgang het die meerderheid van beide die jonger en ouer geslag afhanklik geword van westers-georienteerde voedsel en dit dikwels in hulle eetpatrone ingesluit. Die resultate van hierdie studie het bygedra dat aanbevelings oor die vaslegging en bewaring van die kennis oor inheemse groen blaargroentes in hierdie gemeenskap gemaak kon word, asook om 'n oplewing in die belangstelling in die gebruik daarvan te bevorder.

Résumé :

Background: Children in South Africa are still affected by micronutrient deficiencies and children living in farm communities are especially vulnerable. African Leafy Vegetables (ALVs) are well endowed with micronutrients such as iron, zinc and vitamin A and might contribute to the nutritional status of children. However, these vegetables have been perceived as “poor people’s food” and over the years knowledge of and use of ALVs has decreased. Aim: This study assessed the potential contribution of ALVs to the nutritional status of children in a semi-rural farm community. Method: In this cross-sectional study, anthropometric indices, serum iron, zinc and retinol concentrations were determined in school children aged 5−13 years (n=155). Dietary intake of iron, zinc and vitamin A was evaluated by three 24-hour diet recalls of children (n=154). The iron, zinc and β-carotene content of selected ALVs was determined. Knowledge of and use of ALVs by primary caregivers was established using focus group discussions (FGDs). Descriptive statistics, independent t-tests, the Pearson Chi-Square Test and Mann-Whitney U Test were used. Anthropometric data were analysed using the World Health Organization Reference 2007 data. Dietary data were analysed using FoodFinder (version 3). Qualitative data from FGDs were translated, transcribed and color-coded to generate emerging themes. Results: Stunting (11%) was the most prevalent anthropometric indicator of malnutrition. This was supported by the low socio-economic status of households. Deficiency prevalence in iron (serum ferritin <15 μg/L; 15.5%) and vitamin A (serum retinol <20 μg/dL; 3.2%) was low. Zinc deficiency was the most prevalent (serum zinc <65 μg/dL; 74.8%) deficiency. Median dietary intake of iron, zinc and vitamin A was generally above the Estimated Average Requirement. ALVs were potentially good sources of iron, zinc and β-carotene and could contribute substantially to the Recommended Dietary Allowance for these nutrients in children, without taking into account inhibiting factors that might affect the bioavailability. Iron content of the ALVs studied ranged from 1.4−3.2 mg/100 g edible portion. Amaranthus cruentus was the best source of iron. Zinc content of the ALVs ranged from 0.7−1.4 mg/100g edible portions, with Cleome gynandra having the highest zinc composition. The β-carotene content of the ALVs ranged from 182−314 μg RAE/100 g edible portion, with both Amaranthus cruentus and Cleome gynandra being the best sources. Knowledge of ALVs and their use was indigenous and was transferred between generations. Caregivers had positive attitudes towards the use of ALVs. Conclusion: Although the prevalence of deficiencies was not severe (with exception of zinc deficiency), micronutrient deficiencies exist in the rural farm community studied. ALVs are potentially good sources of iron, zinc and β-carotene and might contribute to the nutritional status of school children. Knowledge of ALVs and the positive attitude and perceptions regarding their use by primary caregivers implied a potentially positive future response to interventions promoting consumption of ALVs in order to contribute to the alleviation of micronutrient deficiencies.

Résumé :

Using farmer surveys the smallholder commodity systems of Brassica rapa L. subsp. chinensis and Solanum retroflexum Dun. in Vhembe District, Limpopo Province, South Africa were described and analysed. Production, transaction and consumption of the two vegetables were deeply embedded in the food, trade and farming systems of local people. The cultivation systems, which appeared effective, were developed by borrowing elements from the systems of other crops to which new knowledge specific to B. chinensis and S. retroflexum were added. Several elements of the production systems that could benefit from scientific enquiry were identified. These included genetic improvement and the optimisation of planting density and nutrient supply.

Résumé :

AbstractTraditionally managed socio-ecological production landscapes (SEPLs) provide communities with a range of goods and services vital for livelihoods, including nutrition and health. In Kenya, many of these landscapes, encompassing the resources therein and the indigenous knowledge vital for optimising their value, are now under threat.Utilising diverse traditional foods for the benefit of local communities has often been hampered by insufficient knowledge about the foods and negative attitudes towards them. For over two decades, a team from the National Museums of Kenya, Bioversity International, and their partners has been working with local communities to find out how local food resources can contribute more to community livelihoods, especially with regard to nutrition, health, and income. Understanding local food systems is a vital step. The team developed a methodology for involving local communities, and the youth in particular, to inventory their foodways. The documentation opened opportunities for research and development interventions. This chapter highlights three development and conservation case studies founded on foodways documentation: (1) promoting African leafy vegetables in Kenya; (2) safeguarding kitete (bottle gourd) by Kyanika Women’s Group in Kitui, Kenya; and (3) utilising digital technology to educate consumers about healthy eating using local foods.All cases have shown that converting underutilised local foods into main sources of nutrition and income opportunities, as well as conserving these foods in their environment, requires foodways documentation, community participation, and multi-stakeholder and multidisciplinary collaboration. Awareness on the nutritional and health benefits of local foods was a key incentive for their conservation and a catalyst for the change in attitudes and eating habits.

Résumé :

AbstractThe impact of climate change, especially on agricultural sector, calls for a global and more localized strategies such as cultivation of underutilized indigenous vegetables (UIVs) which adapt better to local climate change. This chapter, therefore, examines the perception of UIVs farmers to climate change, their experiences of UIVs’ responses to climate change, adaptation strategies employed, and the determinants of the decision to adopt them in Southwest Nigeria. The study uses quantitative and qualitative primary household data from 191 UIVs farmers, 8 Focus Group Discussions (FGDs), and secondary climate data from the Nigerian Meteorological Agency. Descriptive and econometric analyses are employed in the data analyses. The results show that farmers’ perceptions of climate change are high temperature and a high variability in rainfall pattern that has affected the yield, increased insects, pests, and diseases infestations, and reduced soil fertility. The results further show that the responses of UIVs to these resultant effects differ as such, and adaptation strategies farmers adopt are UIVs-specific. The adaptation strategies mostly employed by the UIVs farmers are cultivating UIVs along the river bank and the least is agroforestry and perennial plantation. The determinants of the decision to adopt adaptation strategies include UIVs revenue, age, years of experience, access to climate information, climate change awareness, agro ecological zone, and access to credit. Thus, promotion of UIVs business is advocated and provision of information on climate change essential and will encourage farmers to adopt appropriate climate change adaptation strategies to boost UIVs business.
