In a recent publication, Nassif and Tanji [<xref ref-type="bibr" rid="B1">1</xref>] list almost 80 species used as wild vegetables in Morocco (see table one which lists all wild vegetables, as well as fruits, seeds and other wild foods), identified from francophone grey literature sources and their own anecdotal observation in the field. They note the need for systematic studies of wild foods in Morocco, similar to those that have been carried out in other regions.</p><p>Before Nassif and Tanji’s 2013 [<xref ref-type="bibr" rid="B1">1</xref>] publication only a few wild vegetables species had been list in Morocco in Tanji and Nassif 1995 [<xref ref-type="bibr" rid="B2">2</xref>] and Hadjichambis et al. 2008 [<xref ref-type="bibr" rid="B3">3</xref>]. The gap in scientific documentation may be explained by the seasonal or geographic variation in use, the fact that much of the botanical and ethnobotanical research conducted in Morocco has been overseen by male researchers and wild vegetables are a women’s domain, and the fact that most ethnobotanical work in Morocco focuses on medicinal and aromatic plants. In an effort to further scientific documentation on this topic, this paper documents the distribution and use of wild vegetables across multiple sites in Taounate, Azilal, and El Haouz, using botanical identification and voucher collection. Herein we examine geographic differences in use, diversity, salience and ethnobotanical nomenclature of WLVs. We conclude by examining potential drivers of geographic variation in nomenclature and use.</p><p>Wild vegetables are an important component of traditional food systems around the world [<xref ref-type="bibr" rid="B4">4</xref>,<xref ref-type="bibr" rid="B5">5</xref>]. Wild vegetables are a distinct cultural domain in the knowledge systems of many communities.

Aromatic plants used as seasoning or in tea are not included.</p><p>WLVs are essential to the nutrition and food security of people around the world. WLVs add diversity to the diet; making diets healthier and more interesting [<xref ref-type="bibr" rid="B9">9</xref>-<xref ref-type="bibr" rid="B11">11</xref>]. Studies have shown the significant contribution of WLVs to micronutrient content of local diets in developing countries [<xref ref-type="bibr" rid="B9">9</xref>,<xref ref-type="bibr" rid="B12">12</xref>]. WLVs can be important, not just in times of food scarcity (drought) but throughout the year [<xref ref-type="bibr" rid="B10">10</xref>,<xref ref-type="bibr" rid="B13">13</xref>,<xref ref-type="bibr" rid="B14">14</xref>]. In many cases, WLVs are especially important to socio-economically vulnerable groups [<xref ref-type="bibr" rid="B10">10</xref>] and indigenous populations forced to live on marginal lands for social and political reasons [<xref ref-type="bibr" rid="B15">15</xref>]. In such groups WLVs can decrease people’s dependence on cash-purchased market foods and provide income for those with limited access to land for cultivation of crops [<xref ref-type="bibr" rid="B7">7</xref>,<xref ref-type="bibr" rid="B15">15</xref>].</p><p>The use of WLVs is suggested to be declining around the world [<xref ref-type="bibr" rid="B16">16</xref>], a shift associated with a general nutrition and dietary transition [<xref ref-type="bibr" rid="B17">17</xref>]. Chweya and Eyzaguirre [<xref ref-type="bibr" rid="B16">16</xref>] cite numerous causes for declining use of traditional and wild vegetables in Africa including: decreased availability due to biodiversity loss and change in agricultural practise, government and development policies that ignore WLVs; loss of knowledge needed for gathering and preparation; and a general loss of cultural value for WLVs. Highlighting that at-risk groups suffer the most from decreasing availability of WLVs, are studies showing that it is poor women who first notice declines in availability and diversity of WLVs species [<xref ref-type="bibr" rid="B15">15</xref>,<xref ref-type="bibr" rid="B18">18</xref>]. Socio economic and cultural devaluation is a frequently noted factor in the declining use of WLVs around the world [<xref ref-type="bibr" rid="B16">16</xref>,<xref ref-type="bibr" rid="B19">19</xref>,<xref ref-type="bibr" rid="B20">20</xref>]. In Nepal, nettles (<italic>Urtica</italic> spp.) are eaten by monks living a life of frugality and thus are considered to be part of only the most meagre diet [<xref ref-type="bibr" rid="B15">15</xref>]. In Spain WLVs are seen as old-fashioned’ and time-consuming to collect, despite the fact that many people like the taste and enjoy gathering them [<xref ref-type="bibr" rid="B19">19</xref>]. WLVs are an integral part of the biodiversity of agro-ecosystems that enhances resilience of the traditional food system, and provides local and culturally appropriate options to help mitigate both chronic, diet and over-nutrition related diseases and micronutrient deficiency concurrently [<xref ref-type="bibr" rid="B4">4</xref>,<xref ref-type="bibr" rid="B5">5</xref>,<xref ref-type="bibr" rid="B21">21</xref>].</p><p>This paper reports the results of a free listing exercise for WLVs with women, as well as the botanical identification of many of these species. Data on the frequency of WLV consumption, obtained from a 7 day food frequency questionnaire are reported, followed by qualitative data on perceptions and knowledge of WLVs. The paper also includes an examination of geographic variation in use, salience and nomenclature and a discussion of the potential role of markets in the transmission of knowledge about WLVs. The paper concludes with thoughts on the role of WLV in traditional food systems and nutrition, and the potential role of markets in nutrition education and public health nutrition campaigns in Morocco.</p></sec><sec sec-type="methods"><title>Methods</title><sec><title>Study sites</title><p>Morocco has one of the highest level of biodiversity in the Mediterranean [<xref ref-type="bibr" rid="B22">22</xref>] and is also a country facing significant issues in overcoming malnutrition. The country is undergoing a nutrition transition [<xref ref-type="bibr" rid="B23">23</xref>,<xref ref-type="bibr" rid="B24">24</xref>]: 36.6% of women are estimated to be overweight or obese [<xref ref-type="bibr" rid="B25">25</xref>] while micronutrient deficiencies (especially vitamin A and iron) remain a problem [<xref ref-type="bibr" rid="B26">26</xref>]. The national prevalence of vitamin A deficiency (serum retinol < 20 μg/dl) in children under 5 years old was estimated to be 35.1% in 2007 [<xref ref-type="bibr" rid="B26">26</xref>] and stunting remains a problem, with 23.6% of rural children stunted (Height for age Z score -2 S.D.) [<xref ref-type="bibr" rid="B25">25</xref>]. The country now faces a double burden of disease; with chronic nutrition-related disease and micronutrient deficiency and infectious disease simultaneously problematic. Because WLVs were historically not well documented in the country, efforts to address both micronutrient deficiency and chronic nutrition-related diseases have made little mention of the potential benefits of them and other traditional foods. As is the case elsewhere in the world, the high number of species used, geographical variation in use and nomenclature and lack of nutritional composition data, has surely contributed to the lack of incorporation of WLVs into nutritional and agricultural research and education [<xref ref-type="bibr" rid="B16">16</xref>].</p><p>This paper presents data from 3 ecologically distinct regions: Taounate, Azilal, and El Haouz provinces (Figure <xref ref-type="fig" rid="F1">1</xref>). Taounate is located in the Rif Mountains about 80 km north of Fes in northern Morocco. The main livelihood activity in the area is agriculture; however, although no households involved in the research reported direct participation in cannabis cultivation, many in the area earn some or most of their annual income through involvement in cannabis trade. In Taounate work was conducted primarily in three villages: Izara (IZR), Sidi Sinoun (SSN) and Chachia (CHC). Additional research was also carried out with roadside vendors in Ait Bouhamou (ABH). Azilal is located 160 km east of Marrakech in the High Atlas Mountains (central-eastern Morocco). The area is considered under-developed with limited potential for agriculture and tourism. Within Azilal, research was conducted in 2 villages: Ibiyane (IBN) and Habliss (HBL). El Haouz province covers much the High Atlas Mountains directly south of Marrakech (central-south Morocco). Work was conducted in the village of Tassa Ouirgen, 65 km south (and a bit west) of Marrakech and adjacent to the Toubkal National Park, the center-piece of tourism in the High Atlas Mountains.</p><fig id="F1" position="float"><label>Figure 1</label><caption><p>Map of northern Morocco showing major cities and location of research sites.</p></caption><graphic xlink:href="1746-4269-10-34-1"></graphic></fig><p>The female head of household or primary cook for every household in each village was identified and approached to be interviewed. Each woman consenting to participate in the research responded to the household food frequency questionnaire (FFQ). Additionally they were also asked to provide a free list of all the wild vegetables they could list. Not all women who agreed to respond to the FFQ were willing or able to give a free list (about half the women who responded to the FFQ provided a free list). In Tassa Ouirgen no FFQ was conducted with the six women who gave free lists. In Tassa Ouirgen the women involved were identified as knowledgeable by the community leaders and each other. Informants for the qualitative information collected were encountered during participant observation, field visits and research activities and were not selected using any specific system.

Informants were asked to free list all the “Wild Leafy Vegetables” or “Plants used with/like <italic>Malva</italic> spp.” they could name, with prompting to only include vegetables (not aromatic or medicinal plants) and wild species (not cultivated ones). After a list of local names was compiled, key-informants were asked to take us to collect as many species as possible in each site. Research was conducted over multiple years (2005–2012) as timing for collection of WLV species is complicated by short and variable flowering times. Collections were made, numbered and dried following standard methodologies. Some species were identified <italic>in situ</italic> by Abderrahim Ouarghidi, who has extensive botanical training and experience in Morocco.

These data provide valuable additional empirical evidence in support of previously published lists.</p><p>We also interviewed six vendors selling WLVs on the side of the main road from Taounate to Fes. These six included five men and one woman, all between the ages of 15 and 35 years old from villages near the road. Other vendors along the same section of the road sell fermented milk (lben) and snails. They reported that the types of WLVs they sold included: Sekoum (<italic>Asparagus</italic> spp. from Nassif and Tanji [<xref ref-type="bibr" rid="B1">1</xref>]), Khobiza (<italic>Malva</italic> spp.), Rjel Felous (<italic>Chenopodium</italic> sp, or <italic>Glebionis coronaria</italic> (L.)

We have not identified any wild vegetables that are commonly consumed raw in the household (some may be occasionally eaten raw by children). In Chachia and Sidi Sinoun 78% and 77% of households reported having used WLVs in the past 7 days. Interestingly in Izara, the village with the lowest engagement in agriculture and easiest access to the road, 95% of households reported having used WLVs at least once in the past 7 days. Of the households using WLVs, they were used between one to four times per week, with an average of 1.7 days. Compared to the average 84% of households surveyed in Taounate that had used WLVs in the past week, in Azilal only two households (5%) reported having used WLVs in the past week. It is not possible to determine whether this was due to seasonal differences or differences in use between the two sites.</p><p>We attempted to compare the nutrient composition of the most commonly consumed WLVs in Morocco. Nutrient composition data for wild and indigenous species is notoriously poor [<xref ref-type="bibr" rid="B8">8</xref>,<xref ref-type="bibr" rid="B30">30</xref>]. Although calls for improved data on nutrient composition of wild and traditional foods have done much to stimulate research on this topic across Africa and the Mediterranean [<xref ref-type="bibr" rid="B31">31</xref>,<xref ref-type="bibr" rid="B32">32</xref>], there remains insufficient data on the content of important nutrients in the most commonly used WLV species in Morocco to evaluate their potential contribution to overcoming nutrient deficiencies. For example, although there was some data for <italic>Malva</italic>, the most common genus, there is a large variation in nutrient compositions cited and no composition data specific to Morocco (e.g. [<xref ref-type="bibr" rid="B33">33</xref>]). Moreover, we found no data on the micronutrient content of <italic>Scolymus hispanicus</italic>, one of the common WLVs in Morocco, in any Food Composition Table or in the literature. Further research is clearly needed.</p></sec><sec><title>Qualitative data on perceptions of WLVs</title><p>We encountered both very positive and very negative attitudes towards WLVs. However attitudes are increasingly positive in recent years, although it is unclear whether this is only the case in our research sites or across Morocco. In Taounate (2007) informants told us a local proverb: “<italic>Likayakol bakola Amro maysagad chilogha</italic>/If a child eats too much <italic>bakola</italic> when he is small he will not learn to speak (because <italic>bakola</italic> is meant for animals and animals don’t speak)”. Four households in Chachia (2005) showed marked disdain for the use of WLVs and denied they knew any of their names. These same houses did not report use of WLV. Similar denial of knowledge and use was seen in Azilal (Habliss and Ibiyan) where informants insisted that they only used <italic>Malva</italic> spp. and nothing else, these responses were more common when the interviewer did not speak Berber. However in other cases, women were apologetic that their knowledge about WLVs was limited.</p><p>More recently in El Haouz, some women told us that people prefer WLVs to cultivated/imported vegetables because they taste better and/ or because they have medicinal properties: that they are “hot” (including Malva spp., Nasturtium officinale (R.Br.) and Ferula communis (L.)). Many people (both recently and less recently) have told us WLVs are good for health in general, but others claim they get a stomach ache or diarrhea when they eat WLVs or that WLVs are bad for diabetes. Interesting it has been mostly men who have reported negative health effects of WLVs, and mostly women reporting positive effects. It is possible that misidentification due to insufficient knowledge could lead to some incidences of gastro-intestinal discomfort or more sever toxicity.</p><p>Others reported that WLVs are only used if and when other vegetables are not available. For example in Chachia (2005) we were told that once the Faba beans were ripe, many families would no longer use WLVs. Local women in Tassa Ouirgen (2012) noted that no one in the village dries WLVs but that they thought people used to dry them when there was greater risk of food insecurity, however now that they are developed’ (with greater market integration) people no longer need to dry WLVs.</p><p>Formal education could theoretically influence knowledge and perceptions of WLVs, however very few of the women we interviewed (and very few women in rural Morocco in general) had any formal education, so comparison of those with more and less formal education was not possible. However, there was no evidence of significant differences in knowledge or perceptions due to formal education.</p><p>Everywhere, women had very clear knowledge about specific preparation practices needed to make different species palatable (Figure <xref ref-type="fig" rid="F2">2</xref>). WLVs are most often used as a side dish (eaten with bread) or in couscous. Women readily explained their views on which species need to be mixed to achieve a good taste and texture, as well as the ratios of different species needed. However, opinions differ greatly on this topic, including from one neighbour to the next.</p><fig id="F2" position="float"><label>Figure 2</label><caption><p><bold>Collecting WLVs (left: collection </bold><bold><italic>Malva </italic></bold><bold>spp. Izara, Taounate, right: </bold><bold><italic>Malva </italic></bold><bold>spp. in Sidi Sinoun, Taounate).</bold></p></caption><graphic xlink:href="1746-4269-10-34-2"></graphic></fig></sec><sec><title>Geographic variation in use and nomenclature</title><p>Significant differences in the salience (frequency with which they are reported in free lists and discussed by informants), diversity and nomenclature of species reported can be seen between the three regions of study, as well as between villages within regions (Table <xref ref-type="table" rid="T2">2</xref>). In a study from Benin, Achigan-Dako and colleagues [<xref ref-type="bibr" rid="B34">34</xref>] similarly describe significant variation between phytogeographical regions, demonstrating that geography is a stronger determinant of traditional vegetable use than socio-linguistic group (especially for wild species). From our data, we were also able to identify significant variation in WLV knowledge within geographical regions, in addition to between regions. MDS graphs produced from free lists show the two dimensional relationship between informants’ “knowledge” in each province (Figure <xref ref-type="fig" rid="F3">3</xref>). In Azilal there is greater variation between villages than between informants within each village. In Taounate province, informants in Izara and Sidi Sinoun are intermixed (greater variation between informants than between villages), while informants from Chachia form a distinctive cluster. Because the villages are quite far apart and have very limited social ties, we believe that the overlap between Izara and Sidi Sinoun is due to knowledge transmission occurring in the weekly market that inhabitants of both villages visit regularly (the villages Ibiyane and Habliss in Azilal are geographically very close – closer than Sidi Sinoun and Izara, but use different markets). There was an exceptional diversity of WLV for sale in Ourtzagh market (used by Izara and Sidi Sinoun) relative to all the other markets surveyed. We believe that this may be an important site for horizontal knowledge transmission.</p><table-wrap position="float" id="T2"><label>Table 2</label><caption><p>Differences in species diversity and

Multiple types of transmission process have been identified including: vertical, oblique and horizontal. Vertical transmission occurs when a cultural trait or knowledge is transmitted from a parent (or grandparent) to a child; horizontal transmission is transmission between peers, or individuals in approximately the same generation [<xref ref-type="bibr" rid="B35">35</xref>]. Almost all human food preferences are acquired. The fact that it is difficult to condition food preferences (but not aversions) regardless of palatability, suggests that food preferences are heavily socio-culturally conditioned [<xref ref-type="bibr" rid="B36">36</xref>], presumably through the process of cultural transmission.</p><p>“Markets and other economic institutions do more than just allocate goods and services: they also influence the evolution of values, tastes and personalities” [<xref ref-type="bibr" rid="B37">37</xref>]. Markets and economies can affect the process of cultural transmission (the way in which we acquire values and desires) because economic interactions are personal, strategic and durable connections among people whose identities matter for the outcome [<xref ref-type="bibr" rid="B37">37</xref>]<sup>a</sup>. In other words, markets are an important site of cultural transmission, specifically horizontal cultural transmission, the form of transmission which is associated with rapid change in knowledge and knowledge systems [<xref ref-type="bibr" rid="B38">38</xref>]. Acerbi and Parisi [<xref ref-type="bibr" rid="B39">39</xref>] note that vertical knowledge transmission is more important in small-scale traditional societies whereas horizontal transmission plays a greater role as societies increase their economic activity.</p><p>The effect of economic institutions (trade) on plant knowledge and food plant knowledge has been described by Turner [<xref ref-type="bibr" rid="B40">40</xref>], and Turner and Loewen [<xref ref-type="bibr" rid="B41">41</xref>] in their work on plant nomenclature among indigenous groups on the North West Coast of North America. Their work showed that groups with historical trade relations shared greater similarity in plant names than groups which were geographically closer to each other but who had not traded with each other. Linguistic evidence supports the fact that plant knowledge and nomenclature were exchanged along trade networks in addition to plant material [<xref ref-type="bibr" rid="B41">41</xref>]. Conversely, in a context where markets seem not to be acting to facilitate knowledge transmission, Ogle and colleagues [<xref ref-type="bibr" rid="B9">9</xref>] note greater variation between villages than within villages in number, variety and major species’ of WLVs consumed. The transmission of knowledge within trade networks or markets is distinctly different than cultural diffusion, in which horizontal transmission occurs between groups in close proximity to each other.</p><p>Of the 12 small and medium sized rural markets we worked in across Morocco, WLVs were found for sale in only four of them. Two of these markets were the largest markets in their respective areas, the other two were Ourtzagh, and the market adjacent to it, Galaz (the markets used by people from Sidi Sinoun and Izara). Preventing the loss of WLG knowledge in Morocco will require the maintenance of traditional agricultural systems, and the associated knowledge, and socio-cultural systems [<xref ref-type="bibr" rid="B10">10</xref>,<xref ref-type="bibr" rid="B42">42</xref>]. The maintenance of traditional market systems may be essential for the preservation of the complex traditional food and agricultural systems which they act to integrate. This is particularly true in a country with very high diversity of ecosystems, often within a small geographical area, and a long history of traditional market systems.</p></sec></sec><sec sec-type="conclusions"><title>Conclusions</title><p>Our data contribute to the evidence of a high diversity of WLVs used in Morocco. Research on WLVs has likely been historically limited by the strong social stigma some people ascribe to WLVs, a gender gap between trained botanists who are mainly male and the women who hold the knowledge of WLVs, and, as elsewhere in the world, high geographical variability in local names used. Importantly in Morocco, the very seasonable nature of use and flowering patterns of most WLV species, has made it very difficult to get a complete picture of all the species used, even in sites which have been visited over multiple years.</p><p>Our data show that at least in some regions WLVs were almost universally consumed when in season. This, combined with the fact that increased fruit and vegetable consumption is now believed to be one of the best predictors of a wide range of health outcomes [<xref ref-type="bibr" rid="B43">43</xref>,<xref ref-type="bibr" rid="B44">44</xref>], suggests an important potential for WLVs to contribute to the mitigation of both chronic nutrition-related disease and micronutrient deficiency (if their supply can be sustainably increased and expanded). As in other places, maintenance of knowledge for WLV identification and preparation will be necessary for their continued use [<xref ref-type="bibr" rid="B40">40</xref>,<xref ref-type="bibr" rid="B45">45</xref>]. Knowledge of WLVs in Morocco is clearly highly nuanced, very highly variable, and susceptible to rapid change. WLVs in Morocco provide an extremely interesting case study in which to further study the horizontal and vertical transmission of traditional or local knowledge. In Morocco, markets may be an important site where food preferences and choices are shaped through cultural transmission.</p><p>There is a great need for more research on WLVs in Morocco: nutrient composition, contribution to local diet and nutrition, as well as the potential of WLVs and other traditional foods to play a role in mitigation of the nutrition transition. We need to better understand if and how WLVs and other traditional foods can be incorporated into public health nutrition messages and food-based strategies to mitigate the double burden of nutrition Morocco now faces.</p></sec><sec><title>Endnote</title><p><sup>a</sup>Studies of food brand preferences show that personal contact is the most effective, and peers are most influential (Bowles [<xref ref-type="bibr" rid="B36">36</xref>]).</p></sec><sec><title>Competing interests</title><p>The authors declare that they have no competing interests.</p></sec><sec><title>Authors’ contributions</title><p>BP and AO conceived of the research idea.
