Abstract

Background

Agrobiodiversity is said to contribute to the sustainability of agricultural systems and food security. However, how this is achieved especially in smallholder farming systems in arid and semi-arid areas is rarely documented. In this study, we explored two contrasting regions in Benin to investigate how agroecological and socioeconomic contexts shape the diversity and utilization of edible plants in these regions.

Methods

Data were collected through focus group discussions in 12 villages with four in Bassila (semi-arid Sudano-Guinean region) and eight in Boukoumbé (arid Sudanian region). Semi-structured interviews were carried out with 180 farmers (90 in each region). Species richness and Shannon-Wiener diversity index were estimated based on presence-absence data obtained from the focus group discussions using species accumulation curves.

Results

Our results indicated that 115 species belonging to 48 families and 92 genera were used to address food security. Overall, wild species represent 61% of edible plants collected (60% in the semi-arid area and 54% in the arid area). About 25% of wild edible plants were under domestication. Edible species richness and diversity in the semi-arid area were significantly higher than in the arid area. However, farmers in the arid area have developed advanced resource-conserving practices compared to their counterparts in the semi-arid area where slash-and-burn cultivation is still ongoing, resulting in natural resources degradation and loss of biodiversity. There is no significant difference between the two areas for cultivated species richness. The interplay of socio-cultural attributes and agroecological conditions explains the diversity of food plants selected by communities.

Conclusions

We conclude that if food security has to be addressed, the production and consumption policies must be re-oriented toward the recognition of the place of wild edible plants. For this to happen we suggest a number of policy and strategic decisions as well as research and development actions such as a thorough documentation of wild edible plants and their contribution to household diet, promotion of the ‘’bringing into cultivation” practices, strengthening of livestock-crop integration.

<title>Background</title>
<p>Agrobiodiversity is said to contribute to the sustainability of agricultural systems and food security. However, how this is achieved especially in smallholder farming systems in arid and semi-arid areas is rarely documented. In this study, we explored two contrasting regions in Benin to investigate how agroecological and socioeconomic contexts shape the diversity and utilization of edible plants in these regions.</p>
</sec>
<sec>
<title>Methods</title>
<p>Data were collected through focus group discussions in 12 villages with four in Bassila (semi-arid Sudano-Guinean region) and eight in Boukoumbé (arid Sudanian region). Semi-structured interviews were carried out with 180 farmers (90 in each region). Species richness and Shannon-Wiener diversity index were estimated based on presence-absence data obtained from the focus group discussions using species accumulation curves.</p>
</sec>
<sec>
<title>Results</title>
<p>Our results indicated that 115 species belonging to 48 families and 92 genera were used to address food security. Overall, wild species represent 61% of edible plants collected (60% in the semi-arid area and 54% in the arid area). About 25% of wild edible plants were under domestication. Edible species richness and diversity in the semi-arid area were significantly higher than in the arid area. However, farmers in the arid area have developed advanced resource-conserving practices compared to their counterparts in the semi-arid area where slash-and-burn cultivation is still ongoing, resulting in natural resources degradation and loss of biodiversity. There is no significant difference between the two areas for cultivated species richness. The interplay of socio-cultural attributes and agroecological conditions explains the diversity of food plants selected by communities.</p>
</sec>
<sec>
<title>Conclusions</title>
<p>We conclude that if food security has to be addressed, the production and consumption policies must be re-oriented toward the recognition of the place of wild edible plants. For this to happen we suggest a number of policy and strategic decisions as well as research and development actions such as a thorough documentation of wild edible plants and their contribution to household diet, promotion of the ‘’bringing into cultivation” practices, strengthening of livestock-crop integration.</p>

<title>Background</title>
<p>Agrobiodiversity is understood as “
<italic>the variety and variability of living organisms that contribute to food and agriculture in the broadest sense, and that are associated with cultivating crops and rearing animals within ecological complexes</italic>
” [
<xref ref-type="bibr" rid="CR1">1</xref>
,
<xref ref-type="bibr" rid="CR2">2</xref>
]. A sustainable utilization of agrobiodiversity and associated ecosystem services through diversified farming systems is advocated to be a robust approach for addressing food security and the sustainability of agricultural systems [
<xref ref-type="bibr" rid="CR3">3</xref>
<xref ref-type="bibr" rid="CR8">8</xref>
]. However, how agrobiodiversity is used to address food security and sustainability of agricultural systems in smallholder farming systems in arid and semi-arid areas of West Africa needs to be investigated and documented so as to inform policy decisions. In fact, the challenge of providing sufficient food for the increasing population while preserving natural resources is higher in arid and semi-arid areas [
<xref ref-type="bibr" rid="CR9">9</xref>
,
<xref ref-type="bibr" rid="CR10">10</xref>
]. In these areas, agricultural production systems are faced not only with persistent water scarcity and frequent drought, but also with high climatic variability, land degradation, desertification, and widespread poverty [
<xref ref-type="bibr" rid="CR9">9</xref>
]. The strong climatic variations and irregular rainfalls that characterized agro-ecosystems in dry areas make harvest of staple and cash crops highly uncertain, especially in West African Sahel and dry savannas [
<xref ref-type="bibr" rid="CR11">11</xref>
]. These constraints are expected to intensify as a result of population growth, urbanization and climate change, which will likely exacerbate food insecurity in these areas, that are already vulnerable to hunger and under-nutrition [
<xref ref-type="bibr" rid="CR12">12</xref>
]. In this context, increased knowledge of the functionalities of agrobiodiversity will help build the social and natural science evidence-base to allow formulation of adequate intensification strategies [
<xref ref-type="bibr" rid="CR13">13</xref>
]. These context- and location-specific strategies require a clear understanding of food production and consumption systems.</p>
<p>Previous investigations in West Africa explored the relationships that communities have developed with their environment and surrounding biological resources, including the utilization of plant resources. From those previous findings, we understood that the value and utilization of plant resources in communities are influenced by sociolinguistic membership [
<xref ref-type="bibr" rid="CR14">14</xref>
<xref ref-type="bibr" rid="CR22">22</xref>
] and to some extent geographical contexts [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR24">24</xref>
]. However, gap still exists in the understanding of how ecological and socioeconomic contexts shape the utilization of agrobiodiversity and its contribution to food security in this region. Most studies focus on the consumption and variation of knowledge of single species (e.g.
<italic>Parkia biglobosa</italic>
[
<xref ref-type="bibr" rid="CR14">14</xref>
],
<italic>Sclerocarya birrea</italic>
[
<xref ref-type="bibr" rid="CR15">15</xref>
],
<italic>Tamarindus indica</italic>
[
<xref ref-type="bibr" rid="CR22">22</xref>
,
<xref ref-type="bibr" rid="CR25">25</xref>
],
<italic>Blighia sapida</italic>
[
<xref ref-type="bibr" rid="CR16">16</xref>
],
<italic>Adansonia digitata</italic>
[
<xref ref-type="bibr" rid="CR26">26</xref>
]) or categories of species (e.g. woody species [
<xref ref-type="bibr" rid="CR27">27</xref>
,
<xref ref-type="bibr" rid="CR28">28</xref>
], Non-Timber Forest Products species [
<xref ref-type="bibr" rid="CR20">20</xref>
,
<xref ref-type="bibr" rid="CR29">29</xref>
], vegetables species [
<xref ref-type="bibr" rid="CR24">24</xref>
,
<xref ref-type="bibr" rid="CR30">30</xref>
]) and the linkage between agrobiodiversity, food consumption and security was partially addressed. Food security is a complex condition with four key dimensions namely food availability, food utilization, food accessibility and food system stability [
<xref ref-type="bibr" rid="CR31">31</xref>
]. Understanding how food security is achieved in arid and semi arid areas while sustaining the use of agrobiodiversity will certainly provide insight into plant resources preservations mechanisms, food production strategies, and sustainable livelihoods.</p>
<p>The objectives of this study are to assess the diversity and utilization of edible plant resources, and analyze farming practices in relation to agroecological contexts in agricultural communities of two contrasting regions in Benin. The following questions were addressed in this paper: (1) What are the edible plants used in the arid and the semi-arid regions of Benin and what is the place of wild resources? (2) Is the diversity of edible plants used in the semi-arid and arid regions the same? (3) Are ecological differences between the arid versus semi-arid regions reflected in differences in farming practices and use of edible plant resources? (4) Are edible plants’ choice and utilization similar in communities of the arid and the semi-arid regions? We hypothesized that the use of edible plant resources (wild and cultivated) is affected by agroecological conditions, sociolinguistic attributes and farming practices of rural communities.</p>

<title>Study area</title>
<p>This study was conducted in two ecological regions of Benin (West Africa) namely the Sudanian and the Sudano-Guinean regions. Benin is located on the Atlantic coast, and borders Nigeria to the east, Togo to the west, and Burkina Faso to the northwest, and Niger to the north (Figure 
<xref rid="Fig1" ref-type="fig">1</xref>
). The vegetation pattern shows a humidity gradient northward as a result of the joint effects of the climate and the soils [

<p>The Sudanian region is a woodland and savanna region with ferruginous soils. The rainfall is unimodal with a mean annual for about 1000 mm (Table 
<xref rid="Tab1" ref-type="table">1</xref>
). The temperature ranges from 24 to 31°C [
<xref ref-type="bibr" rid="CR32">32</xref>
,
<xref ref-type="bibr" rid="CR33">33</xref>
]. The main sociolinguistic groups are Bariba, Fulani and Otamari and related sociolinguistic groups [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Farming systems are mainly based on cotton and cereal cultivation and livestock breeding. In the Western part, farming systems are limited by both land degradation and availability leading to population migration into central part of the country [

<p>The Sudano-Guinean region is a transitional zone between the Guinean forests in the south and the Sudanian woodlands and savannas in the north and is characterized by a vegetation mosaic of forest islands, gallery forests, and savannas. The rainfall is unimodal and lasts for about 200 days with an annual mean rainfall varying from 1100 to 1300 mm (Table 
<xref rid="Tab1" ref-type="table">1</xref>
). The temperature varies from 25 to 29°C [
<xref ref-type="bibr" rid="CR32">32</xref>
,
<xref ref-type="bibr" rid="CR33">33</xref>
]. The main sociolinguistic groups are Fon, Yoruba-Nagot and related sociolinguistic groups [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Other ethnic groups found include Otamari, Yom-Lokpa and related sociolinguistic ethnics groups. These ethnic groups represent two sociolinguistic groups that form the principal actors of migratory dynamics in Benin [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR36">36</xref>
]. Members of these groups are motivated to leave their homes in the hilly and over-populated North-West part to the central part in search of the virgin and fertile lands [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR35">35</xref>
<xref ref-type="bibr" rid="CR37">37</xref>
]. Fulani herders are also found in the Sudano-Guinean region because of their nomadic pastoralist lifestyle. The yam-based cropping systems are dominant [
<xref ref-type="bibr" rid="CR35">35</xref>
] while rice cultivation is also important. Cotton and cashew nut are the major cash crops in the Sudano-Guinean zone.</p>
<p>Based on biophysical and socio-economic gradients [
<xref ref-type="bibr" rid="CR32">32</xref>
,
<xref ref-type="bibr" rid="CR33">33</xref>
,
<xref ref-type="bibr" rid="CR38">38</xref>
,
<xref ref-type="bibr" rid="CR39">39</xref>
], we selected Boukoumbé and Bassila municipalities for field investigations (Table 
<xref rid="Tab1" ref-type="table">1</xref>
, Figure 
<xref rid="Fig1" ref-type="fig">1</xref>
). Boukoumbé (10°10'36.1"N and 01°06'22.0"E) is located in Atacora department (north-western Benin) and belongs to the arid Sudanian region. Main ethnic groups in Boukoumbé include Ditamari, M’Berme, Natimba and Berba, which form the Otamari socilolinguistic group [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Otammari ethnic groups compose 92.4% of the population of Boukoumbé [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Traditional social system of the Otammari is based on crop production [
<xref ref-type="bibr" rid="CR36">36</xref>
,
<xref ref-type="bibr" rid="CR40">40</xref>
]. Limited access to arable land due to the Atakora mountain chain and land degradation lead Otammari people to leave their homes to the central part of the country [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR35">35</xref>
<xref ref-type="bibr" rid="CR37">37</xref>
]. The total population of Boukoumbé is 60568 with a population density of 58 habitants per km
<sup>2</sup>
[
<xref ref-type="bibr" rid="CR41">41</xref>
]. The total land area is 1036 km
<sup>2</sup>
. Eighty six percent of household depend primarily on agriculture for their livelihood [
<xref ref-type="bibr" rid="CR41">41</xref>
]. About 72% of households in the department of Atacora (in which belongs Boukoumbé) are poor (the highest proportion at national level) and 51% of its population live in extreme poverty [
<xref ref-type="bibr" rid="CR38">38</xref>
]. To reduce this severe food insecurity an emergency programme of the Benin government was implemented from 2009 to 2011 through various emergency projects [
<xref ref-type="bibr" rid="CR39">39</xref>
]. Bassila (09°01'00.1"N and 01°40'00.1"E) is located in Donga department of (upper central Benin) and belongs to the semi-arid Sudano-Guinean region. Main ethnic groups in Bassila include in order of importance Nagot, Anii and Kotokoli ethnic groups [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Nagot people are considered as native dwellers of Bassila although they have known to be originated from Yoruba people of Nigeria with whom they share indeed many similarities [
<xref ref-type="bibr" rid="CR23">23</xref>
]. Anii and Kotokoli originated from Togo. Other ethnic groups such Otamari, Lokpa and Fulani are found in Bassila due to population migration. Indeed, Bassila as well as other municipalities in the transitional Sudano-Guinean zone between the Sudanian zone in the north and the Guinean zone in the south, is a receptacle of strong dynamic migration [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR36">36</xref>
]. Otamari are from the Atakora mountain chain region while Lokpa people are from municipality of Ouaké (in northern Bassila) [
<xref ref-type="bibr" rid="CR34">34</xref>
]. Apart Fulani who has a nomadic pastoralist lifestyle, other ethnic groups in Bassila are mainly tillers [
<xref ref-type="bibr" rid="CR34">34</xref>
,
<xref ref-type="bibr" rid="CR40">40</xref>
]. The total population of Bassila is 71511 with a population density of 13 habitants per km
<sup>2</sup>
[
<xref ref-type="bibr" rid="CR41">41</xref>
]. The total land area is 5661 km
<sup>2</sup>
. Currently, Bassila is the second largest municipality of Benin and about half of its total land area is covered with forests. Eighty three percent of household depend primarily on agriculture for their livelihood [
<xref ref-type="bibr" rid="CR41">41</xref>
]. About 40% of households in the department of Donga (in which belongs Bassila) are poor with 20% of its population living in extreme poverty [
<xref ref-type="bibr" rid="CR38">38</xref>
]. Also, Bassila is in a moderate but steady food insecurity situation [

<title>Data collection</title>
<p>In each municipality, we identified main agricultural production zones with local extension service agents. Afterwards, villages were randomly selected in these zones and the number of villages by municipality is proportional (11 to 12%) to the total number of villages that each municipality holds. Bassila holds 31 villages whereas Boukoumbé holds 71 villages [
<xref ref-type="bibr" rid="CR41">41</xref>
]. We surveyed four villages in Bassila (Adjiro, Aoro-Lokpa, Camp pionier and Mondogui) and eight villages in Boukoumbé (Dimatema, Dipokor 1, Ditchendia, Koukongou, Kounadogou, Koutchata, Okouaro and Tassayota). Each surveyed village exhibit a dominant sociolinguistic group. A sociolinguistic group is understood here as a group in which a member inherits a common language of communication and shares social attributes such as customs, history, and food habits as recognized by Achigan-Dako
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR24">24</xref>
]. We carried out a focus group discussion in each village with about 20 community members and with a balanced representation of men, women, and different age groups. The socially defined age classes (youth - an unmarried individual; an adult - an individual married, but not considered an elder; and elder [
<xref ref-type="bibr" rid="CR42">42</xref>
]) were considered. Participants in focus group discussions are community’s members locally recognized as knowledgeable about edible plants. Those participants were invited by the chief of the village and their peers. We obtained a permission of the chief of each village before conducting a focus group discussion, and followed the ethical guidelines of the International Society of Ethnobiology [
<xref ref-type="bibr" rid="CR43">43</xref>
]. Participants were asked to build a free and an agreed list of edible plants consumed in the villages and to indicate their status (e.g. cultivated, wild or under domestication), utilizations and plant parts used. For local people, a “cultivated” species is a crop plant that is only known to be cultivated in the village; a “wild” species referred to any other food plants ranging from truly wild (entirely wild and collected only when needed) to wild-protected (maintained and protected or preserved in fields and fallows or around habitats with a sort of ownership), and semi-domesticated plants (cultivated in home gardens or in selected parts of cultivated fields where farmers tend to conduct diverse experiments); an “under domestication” species referred to plants of “wild” category that are not considered fully cultivated yet, and are no longer considered truly wild. It includes wild-protected and semi-domesticated plants, and species that are cited as cultivated by some participants and as wild by other during focus group discussion. Cultivated plants that grow spontaneously in the bush or fallow were not considered as wild species. At the end of each focus group, a guided tour was organized in the village to collect vouchers of edible plants previously listed (by their local names) by participants. The vouchers were selected with the help of two informants who were consensually selected among the participants. Species were taxonomically identified following Akoègninou
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR33">33</xref>
]. We also used the illustrated reference book of traditional vegetable species in Benin [
<xref ref-type="bibr" rid="CR44">44</xref>
] and an illustrated reference book of trees, shrubs and lianas of dry zones of West Africa [
<xref ref-type="bibr" rid="CR45">45</xref>
] to identify plant species. Voucher specimens were sent to the National Herbarium of Benin at University of Abomey-Calavi for further taxonomic confirmation.</p>
<p>In addition to focus group discussions, we carried out semi-structured individual interviews with 90 farmers in each municipality using a questionnaire. Participants were randomly selected and included in the survey after obtaining their verbal prior informed consent. Participant included is an individual who has his farm and hold the decision-making of activities to be implemented on it. Farmers were asked to describe their farming practices starting from land clearing and preparation until post-harvest practices on field.</p>

<title>Data analysis</title>
<p>To estimate edible plant species richness in the two municipalities, we translated the utilization patterns of village communities into presence-absence data to generate species accumulation curve using EstimateS statistical device [
<xref ref-type="bibr" rid="CR46">46</xref>
]. The species accumulation curve represents the number of edible plant species as a function of some measure of the sampling effort employed in the surveys. It yields the asymptotic richness of the assemblage and the computation of the asymmetrical confidence interval of the estimates [
<xref ref-type="bibr" rid="CR46">46</xref>
,
<xref ref-type="bibr" rid="CR47">47</xref>
]. To assess the diversity of edible plant species in the two municipalities, we used the Shannon-Wiener index computed in EstimateS based on the species accumulation curve [
<xref ref-type="bibr" rid="CR46">46</xref>
].</p>
<p>To compare the estimated edible plants species’ richness and diversity between the two areas and between cultivated and wild groups, we performed a
<italic>t</italic>
-test, a Welch’s test or a two-sample Wilcoxon test when appropriate. We used
<italic>t</italic>
-test when normality and homoscedasticity assumptions were met, Welch’s test when normality assumptions was met but not homoscedasticity and two-sample Wilcoxon test when normality and homoscedasticity assumptions were not met [
<xref ref-type="bibr" rid="CR48">48</xref>
]. Shapiro-Wilk’s test for normality and Levene’s test for equality of error variances were used to test the normality and the homoscedasticity assumptions respectively. We also used a range of descriptive statistics to account for species diversity and use patterns.</p>
<p>To test if farming practices used by farmers were independent of their agroecological region, we used Fischer’s exact test or chi-square test when appropriate. Fischer’s exact test was used when some cells of the contingency table had frequencies less than five and these cells represent more than 20% of the total number of cell in the contingency table [
<xref ref-type="bibr" rid="CR48">48</xref>
,
<xref ref-type="bibr" rid="CR49">49</xref>
].</p>
<p>To assess relationships among village communities in term of the utilization of edible plants species, we performed a hierarchical cluster analysis based solely on cultivated species, on wild species and then wild and cultivated together. Dendrograms were obtained using the complete linkage algorithm based on Jaccard coefficient of similarity [
<xref ref-type="bibr" rid="CR50">50</xref>
] generated from the presence–absence data matrix in which villages were considered as sampling units and species as variables and scored, for each village, as 1 when present or 0 if not. All statistical analyses were performed using R version 3.0.2 [

<title>Diversity and richness of edible plants species and farming context in semi-arid and arid regions</title>
<p>The total edible plant species richness was estimated to vary between 110 and 122 with an absolute value of 115 species (Figure

a). Species belong to 48 families and 92 genera. Families with the highest genera and species richness include Asteraceae, Poaceae, Anacardiaceae, and Cucurbitaceae. The first two had 6 genera, each one with 8 and 7 species respectively, whereas the last two had 5 genera each one with 7 and 6 species respectively (Table 
<xref rid="Tab2" ref-type="table">2</xref>

<p>Estimation of cultivated species richness indicated 45 species with Confidence Interval (CI) of 42 to 48 species belonging to 23 families and 38 genera. They are dominated by vegetable (47%) species (e.g.
<italic>Abelmoschus esculentus</italic>
,
<italic>Corchorus olitorius</italic>
,
<italic>Solanum macrocarpon</italic>
,
<italic>Vernonia amygdalina</italic>
) and fruit (20%) species (e.g.
<italic>Citrus sinensis</italic>
,
<italic>Mangifera indica</italic>
,
<italic>Psidium guajava</italic>
). Cereals (e.g.
<italic>Oryza sativa</italic>
,
<italic>Sorghum bicolor</italic>
,
<italic>Zea mays</italic>
) and pulses (e.g.
<italic>Arachis hypogea</italic>
,
<italic>Glycine max</italic>
,
<italic>Vigna unguiculata</italic>
) accounted for 24% of cultivated species and roots and tubers for 13% (e.g.
<italic>Colocasia esculenta</italic>
,
<italic>Dioscorea cayenensis–rotundata</italic>
complex,
<italic>Ipomoea batatas</italic>
,
<italic>Manihot esculenta</italic>
).</p>
<p>The estimated wild edible species richness indicated 70 species (CI: 66–76) representing 61% of edible plants collected. They also represent 46% of the most cited species (species cited in more than 50% of surveyed villages) by communities (Table 
<xref rid="Tab3" ref-type="table">3</xref>
). About 25% of them are under domestication and had dual status depending on the village. Some species are entirely wild and collected only when needed (e.g.,
<italic>Ceratotheca sesamoides</italic>
,
<italic>Cissus populnea</italic>
), others are maintained in agricultural environments (fields and fallow) or around habitats (e.g.,
<italic>Adansonia digitata</italic>
,
<italic>Vitellaria paradoxa</italic>
,
<italic>Parkia biglobosa</italic>
,
<italic>Blighia sapida</italic>
) and others have dual status depending on the village (e.g.,
<italic>Sesamum radiatum</italic>
,
<italic>Hibiscus asper</italic>
,
<italic>Justicia tenella</italic>
,
<italic>Corchorus tridens, Talinum triangulare</italic>
). Wild edible species belong to 38 families and 61 genera. Vegetable species represent about 57% while fruit species account for roughly 47% of wild edible plants collected. Several life forms were recorded, but dominated by trees (36%) and herbaceous species (33%). Many wild species (41%) have multiple edible parts, including edible leaves, fruits, flowers, pulps, kernel, and/or seeds (e.g.
<italic>Adansonia digitata</italic>
,
<italic>Annona senegalensis</italic>
,
<italic>Blighia sapida</italic>
,
<italic>Cissus populnea</italic>
). About 96% of herbs are used as vegetables whereas about 80% of tree species provide fresh fruits (Table 
<xref rid="Tab4" ref-type="table">4</xref>
). Shrubs provide fruits (56%) and also used as vegetable (39%). Other uses (about 50%) were recorded for shrubs and included purgative and laxative (e.g.
<italic>Tamarindus indica</italic>
), stimulation of milk production in lactating women (e.g.
<italic>Zanthoxylum zanthoxyloides</italic>
), toothbrush (e.g.
<italic>Vernonia amygdalina</italic>
). Comparison of estimated richness between wild and cultivated species indicated that wild plant richness is significantly higher than cultivated species richness (Figure

<p>The estimation of species richness per region indicated 99 species (CI: 94–104) with about 60% of wild species (59 species) in Bassila and 82 species (CI: 79–89) with about 54% of wild species (44 species) in Boukoumbé. Overall, edible species richness in Bassila was significantly higher than in Boukombé (Figure 
<xref rid="Fig3" ref-type="fig">3</xref>
a, p < 0.05). The same trend was observed when taking into account only wild species (Figure 
<xref rid="Fig3" ref-type="fig">3</xref>
b, p < 0.01). However, there is no significant difference between the two areas when considering only cultivated species (Figure 
<xref rid="Fig3" ref-type="fig">3</xref>
c, p = 0.1334). Thirty five out of 45 cultivated species collected are shared by the two areas (e.g.
<italic>Zea mays</italic>
,
<italic>Sorghum bicolour</italic>
,
<italic>Vigna unguiculata</italic>
,
<italic>Arachis hypogea</italic>
,

<italic>Manihot esculenta</italic>
,
<italic>Abelmoschus esculentus</italic>
,
<italic>Corchorus olitorius</italic>
,
<italic>Mangifera indica</italic>
,
<italic>Psidium guajava</italic>
). Main species only cultivated in Bassila include
<italic>Ananas comosus</italic>
and
<italic>Elaeis guineensis. Digitaria exilis</italic>
, D.
<italic>iburua</italic>
and
<italic>Pennisetum glaucum</italic>
are the three species only found in Boukoumbé.</p>
<p>The Shannon-Wiener diversity index was high, up to 4.5 for all categories and followed an asymptotic function against the sample frequency (Figure 
<xref rid="Fig2" ref-type="fig">2</xref>
b). Wild species diversity is significantly higher than cultivated species diversity (Figure 
<xref rid="Fig2" ref-type="fig">2</xref>
b, p < 0.001). The Shannon-Wiener diversity index was equally high in the two regions. It was close to 4.5 and 4.2 in Bassila and Boukoumbé respectively. Overall, edible species diversity in the semi-arid Sudano-Guinean area was significantly higher than in the arid Sudanian area (Figure 
<xref rid="Fig4" ref-type="fig">4</xref>
a, p < 0.001). The same trend is observed when taking into account only wild species (Figure 
<xref rid="Fig4" ref-type="fig">4</xref>
b, p < 0.001) and also cultivated species only (Figure 
<xref rid="Fig4" ref-type="fig">4</xref>
c, p < 0.001).</p>
<p>Although about 83% of respondents indicated that they had livestock, livestock breeding differed significantly between the two areas. More farmers were involved in livestock breeding in arid area than in semi-arid one (Figure 
<xref rid="Fig5" ref-type="fig">5</xref>
, p < 0.001). The majority of them explained that livestock resources are used for household needs (e.g., consumption, cultural ceremonies) and commercialized to earn additional financial resources. They argued that this supplementary resource is crucial not only during food shortage period but also during agricultural work period. Animal species raised were dominated by poultry and small ruminants (Figure 
<xref rid="Fig5" ref-type="fig">5</xref>
).</p>
<p>Although farmers in Bassila exploit an overall higher edible plant diversity compared to their counterpart in Boukoumbé, this is not necessary translated into resource-conservation practices. Land clearing and land preparation practices developed were region-dependent (Figure 
<xref rid="Fig6" ref-type="fig">6</xref>
, p < 0.001). Farmers in the semi-arid area used fire to clear new land. On old fields seedling and sapling are pruned and burnt. They also used human traction and to some extent tractors. We noticed no tillage. In the drier area however, the majority of farmers indicated that they use herbicide to clear land. Animal traction is used for tillage and mulches are systematically incorporated during the tillage as soils are degraded. Soil fertility management practices were also region-dependent (Figure 
<xref rid="Fig7" ref-type="fig">7</xref>
, p < 0.001). Chemical fertilizer, animal manure, mulch incorporation and mulching were more used by farmers in the arid area while farmers in the semi-arid area still relied on slash-and-burn cultivation, crop rotation, burning of crop residue and mulches, and mixed-cropping. Similarly, field management practices after harvest were related to region where farmers were living (Figure 
<xref rid="Fig8" ref-type="fig">8</xref>
, p < 0.001). Farmers in the semi-arid area left fields for fallow and/or burnt crop residues. They explained that burning crop residues after harvest reduces weed pressure at beginning of the next cropping season. It also avoids attracting the nomadic Fulani people and their herds into their fields because cattle increase soil degradation and make tillage labour difficult at the next cropping season. However, farmers in the arid area left fields for fallow and/or grazed their own cattle and small ruminants on the fields. They explained that crop residues serve as fodder for their livestock and the manure serves as fertilizer to crops. Contrary to others farming practices, there is no significant difference between the two municipalities regarding pest management practices (Figure 
<xref rid="Fig9" ref-type="fig">9</xref>
, p = 0.1974). Farmers widely used chemical insecticide in both regions, mainly on cotton and to some extent on cowpea.

<title>Relationship among communities in term of choice of edible plants</title>
<p>To understand the impact of agroecological context and socio-cultural attributes on edible plants selection by a community, we performed a cluster analysis using villages as operational units (Figures 
<xref rid="Fig10" ref-type="fig">10</xref>
,
<xref rid="Fig11" ref-type="fig">11</xref>
and
<xref rid="Fig12" ref-type="fig">12</xref>
). Each village is dominated by only one sociolinguistic group. The dendrogram in Figure 
<xref rid="Fig10" ref-type="fig">10</xref>
presents data on all edible plants together. At 40% of similarity, it shows two groups that revealed the two phytogeographical zones. Cluster A1 is composed of all villages of Bassila and no clear grouping according to sociolinguistic membership was noted within the cluster. Cluster A2 is composed of all villages of Boukoumbé. There is no clear grouping according to sociolinguistic membership too. The dendrogram in Figure 
<xref rid="Fig11" ref-type="fig">11</xref>
is based solely on cultivated species, and shows at 40% of similarity two groups based on phytogeographical zones. Cluster B1 is composed of all villages of Sudano-Guinean municipality and Cluster B2 of all villages of Sudanian municipality. There is no clustering according to sociolinguistic membership. The data in Figure 
<xref rid="Fig12" ref-type="fig">12</xref>
take into account wild species only, the same trend was observed although this topology revealed three clusters: Cluster C1 composed of all villages of Sudanian region, Cluster C2 composed of one village (Modogui, a Nagot socio-linguistic community) of Sudano-Guinean region and Cluster C3 of the rest of villages (which are of immigrant community) of Sudano-Guinean region.

<title>Discussion</title>
<p>To the best of our knowledge, this is the first empirical study in Benin as well as in West Africa comparing the diversity of edible plants used by communities in two contrasting areas (in terms of ecological and socioeconomic characteristics). Similarly, exploring how communities produce their crops (farming practices’ analysis) combined with what they used as food plants (edible food plants diversity analysis) give new insights on local people food basket.</p>
<p>The total number of 115 species consumed as food plants in the two municipalities is considerable. It represents about 4% of the floristic diversity of the whole country [
<xref ref-type="bibr" rid="CR33">33</xref>
]. Among the bulk of food plants used, wild species represent 61% (70 species) and 46% of the most cited species by communities. The number of wild edible plants used in the two municipalities represents 43% of the total number of non-wood edible forest plant resources collected during a country-wide market survey in Benin [
<xref ref-type="bibr" rid="CR52">52</xref>
] and is lower than the diversity of noncultivated plant species (87 species) collected in the southwest Benin and the southeast Togo [
<xref ref-type="bibr" rid="CR53">53</xref>
]. Vegetable species represent about 57% while fruit species account for roughly 47% of wild edible plants collected. This highlights the potential role of wild vegetables and fruits in improving food and nutritional security of rural communities [
<xref ref-type="bibr" rid="CR54">54</xref>
<xref ref-type="bibr" rid="CR56">56</xref>
]. Wild species provide various food products for household’s daily diets, especially for poorer households in northern Benin [
<xref ref-type="bibr" rid="CR40">40</xref>
]. Our results indicate that in dry areas wild plants still constitute an important asset in addressing food security by ensuring the availability and accessibility of food plants. Their contribution to food security in rainforest regions has also been demonstrated [
<xref ref-type="bibr" rid="CR57">57</xref>
,
<xref ref-type="bibr" rid="CR58">58</xref>
]. According to Bharucha and Pretty [
<xref ref-type="bibr" rid="CR59">59</xref>
] wild plants and animals continue to form a significant proportion of the global food basket, and their roles and values in agricultural systems may be set to grow as pressures on agricultural productivity increase. Based on our results, we emphasize the important value of wild edible resources in food consumption in dry areas. Their roles in farmers’ global livelihoods are likely to be more important, as reported by many authors [
<xref ref-type="bibr" rid="CR22">22</xref>
,
<xref ref-type="bibr" rid="CR29">29</xref>
,
<xref ref-type="bibr" rid="CR40">40</xref>
,
<xref ref-type="bibr" rid="CR57">57</xref>
,
<xref ref-type="bibr" rid="CR60">60</xref>
<xref ref-type="bibr" rid="CR62">62</xref>
]. The improvement of food security in developing countries will depend on the placement of wild edible resources in agricultural policies as well. A thorough documentation of wild edible plants and their contribution to household diet will help improve knowledge on the under-valued biological and cultural diversity that are of importance to address food security, environmental and economic sustainability [
<xref ref-type="bibr" rid="CR63">63</xref>
]. Moreover, a diversification with greater use of highly valuable but presently under-utilized crops and species should be an essential element of any model for sustainable smallholder agriculture [
<xref ref-type="bibr" rid="CR4">4</xref>
].</p>
<p>About 25% of wild edible plants are under domestication and can be found in one or other step in the “bringing into cultivation” phase of the plant domestication process described by Vodouhè and Dansi [
<xref ref-type="bibr" rid="CR64">64</xref>
]. Some species are entirely wild and collected only when needed, others are maintained in agricultural environments (fields and fallow) or around habitats and others have dual status depending on the village. Asteraceae and Cucurbitaceae families, which are among the most important plant families, also showed a high vegetable species richness in Benin and Togo [
<xref ref-type="bibr" rid="CR24">24</xref>
,
<xref ref-type="bibr" rid="CR30">30</xref>
]. These findings reveal the importance of these species and botanical families to farmers and to food diets as well. Indeed, food uses is the main reason that motivates local communities in Benin for plant domestication [
<xref ref-type="bibr" rid="CR64">64</xref>
]. Therefore, there is a need to consolidate the on-going researches on domestication process of some of species such as
<italic>S. radiatum</italic>
,
<italic>J. tenella</italic>
,
<italic>A. digitata</italic>
,
<italic>V. doniana</italic>
,
<italic>C. rubens</italic>
and
<italic>C. crepidioides</italic>
[
<xref ref-type="bibr" rid="CR24">24</xref>
,
<xref ref-type="bibr" rid="CR60">60</xref>
,
<xref ref-type="bibr" rid="CR65">65</xref>
<xref ref-type="bibr" rid="CR71">71</xref>
] to ensure and enhance the availability, accessibility, and utilization food plants. Moreover, the promotion of the ‘’bringing into cultivation” practices contributes to not only plant domestication but also to promoting diversity, increasing its sustainable utilization and conservation of agrobiodiversity
<italic>in situ</italic>
[
<xref ref-type="bibr" rid="CR64">64</xref>
].</p>
<p>Trees, shrubs and lianas account for about 70% of wild edible plants collected. Many of them are maintained in agricultural environment forming the so called “agroforestry parklands”, a widespread traditional land use system in West African dry savannas in which trees and shrubs are intentionally spared and let scattered on farmlands and fallows [
<xref ref-type="bibr" rid="CR72">72</xref>
]. Indeed, agroforestry systems offer a number of ecosystem services and environmental benefits, including soil fertility improvement, soil and water conservation, and environmental protection by maintaining ecological stability and conservation of biodiversity [
<xref ref-type="bibr" rid="CR73">73</xref>
]. These ecosystem functions have been at the centre of the local ecological knowledge guiding the management options of the farmers [
<xref ref-type="bibr" rid="CR74">74</xref>
]. As evidenced by Assogbadjo
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR75">75</xref>
] wild edible species retained in agroforestry systems in Benin depends on farmers’ knowledge on species contribution to food, its use in traditional medicine and ceremonies and farmers’ perception of its availability in natural vegetation. By regulating ecosystem functions such as nutrient recycling, water use, species diversity and agrochemical pollution agroforestry can sustain agricultural intensification and food security in Africa [
<xref ref-type="bibr" rid="CR76">76</xref>
,
<xref ref-type="bibr" rid="CR77">77</xref>
]. Moreover, agroforestry systems promote integrated management systems that relate livelihoods and ecosystem service functions to agricultural production and is therefore often considered as a way to sustainably intensify farming practices for enhanced food security, using socially and cost-effective management techniques [
<xref ref-type="bibr" rid="CR76">76</xref>
,
<xref ref-type="bibr" rid="CR78">78</xref>
]. Thus, the improvement of agroforestry practices will benefit wild edible plants and enhance the role of these systems in biodiversity conservation and food provision.</p>
<p>Our study revealed that edible species richness and diversity declines from the semi-arid to the arid zone. Moreover, the diversity of wild edible plants used in Bassila (59 species) is higher than in the buffer zone of the Lama forest in southern Benin (48 botanically identified plants) [
<xref ref-type="bibr" rid="CR58">58</xref>
]. It is also higher than in other localities in the Sudano-Guinean region (41 wild edible plants in the buffer zone of the Dan forest in Djidja District [
<xref ref-type="bibr" rid="CR60">60</xref>
] and 40 wild edible plants in the Collines region in central Benin [
<xref ref-type="bibr" rid="CR21">21</xref>
]). These findings are consistent with results from Achigan-Dako
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR24">24</xref>
] and Salako
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR79">79</xref>
] in Benin on traditional vegetable and home gardens species respectively. This trend could be explained by the fact that in West Africa diversity tends to decline with declining precipitation and from south to north [
<xref ref-type="bibr" rid="CR80">80</xref>
]. This south–north climatic gradient which results from the combining effects of annual rainfall, length and severity of the dry season, and air humidity, the soils and geological factors are the major environmental factors underlying plant diversity patterns [
<xref ref-type="bibr" rid="CR81">81</xref>
]. Other socio-cultural drivers may also explain this situation. Indeed, the Sudano-Guinean region is a transitional zone between the humid Guinean region in the south and the drier Sudanian region in the north and is a receptacle of strong dynamic migration [
<xref ref-type="bibr" rid="CR23">23</xref>
]. The transitional attribute combined with cultural exchange and population migrations within the region could contribute to the observed greater edible species richness and diversity. Cultivated species richness and composition did not significantly differ between the semi-arid and the arid areas. Therefore, the overall difference observed in species richness among the two regions is attributed to wild species. However, as evidenced by Mulumba
<italic>et al.</italic>
[
<xref ref-type="bibr" rid="CR82">82</xref>
], the use of crop varietal diversity is a risk-minimizing strategy, we speculate that varietal diversity and richness used might be higher in the arid Sudanian zone.</p>
<p>Achieving food security in arid and semi-arid regions of Benin requires productive agriculture, and the wide range of edible plant diversity and farming practices [
<xref ref-type="bibr" rid="CR2">2</xref>
] should not be overlooked. A comparative analysis of farming system between the two regions indicated that farming practices were significantly related to phytogeographical regions except for pest management practices. Slash-and-burn is still ongoing in semi-arid Sudano-Guinean area as environmental conditions (e.g. precipitation, soil, plant diversity) are more favourable. Fire and burning were heavily used in land preparation, soil fertility management and field management after harvest. New land is converted each year to agriculture, reducing forests and savannas. Cotton expansion is a main driver of forests, savannas and land degradation resulting in loss of biodiversity in West African savannas [
<xref ref-type="bibr" rid="CR83">83</xref>
<xref ref-type="bibr" rid="CR85">85</xref>
]. In the arid Sudanian area farmers have developed more resource-conserving practices as a consequence of land degradation and climatic constraints that they face. They integrate more livestock resources to meet their livelihood needs. As a result they use animal manure for soil fertility management, animal traction for tillage, and graze their livestock on their fields after harvest. We recommended that extension services take into account differences between the two areas and provide farmers with insights and technologies on appropriate crops based on land and resources availability. At the same time, account should be given to intensive awareness-raising about best farming practices. Sustainable or resource-conserving farming practices developed by farmers in less favourable areas need to be strengthened and supported, and also promoted in more favourable areas so as to preserve agroecosystem and natural resources for upcoming generations. Indeed, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities [
<xref ref-type="bibr" rid="CR86">86</xref>
]. Moreover, the strengthening of livestock-crop integration is crucial for ecological intensification of agriculture to achieve current and future food security and environmental sustainability [
<xref ref-type="bibr" rid="CR87">87</xref>
].</p>
<p>Many findings highlighted the importance of socio-cultural attributes in the utilization and values that a community gives to plant resources [
<xref ref-type="bibr" rid="CR14">14</xref>
<xref ref-type="bibr" rid="CR16">16</xref>
,
<xref ref-type="bibr" rid="CR18">18</xref>
<xref ref-type="bibr" rid="CR22">22</xref>
]. This is illustrated in Figures 
<xref rid="Fig10" ref-type="fig">10</xref>
and
<xref rid="Fig12" ref-type="fig">12</xref>
, where socio-cultural attributes are indicated to play an important role in plant use. For instance, in Cluster A1 Modogui, a Nagot sociolinguistic group village stands alone; Aoro-Lokpa and Adjiro, two Lokpa villages, are grouped into the same sub-cluster while Camp pionier, a Ditamari sociolinguistic group stands alone. Cluster A2 is composed of Ditamari and M’Bermé, two ethnic groups that have high linguistic and cultural affinities. These two ethnic groups formed with other minor ethnic groups the Otamari linguistic group. Ditamari (in general term Otamari group) and Lokpa from the Sudanian region are two ethnic groups that are the principal actors of migratory dynamics in Benin [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR36">36</xref>
]. Members of these groups are motivated to leave their homes in Atacora because of soil degradation, in search of the virgin and fertile lands [
<xref ref-type="bibr" rid="CR23">23</xref>
,
<xref ref-type="bibr" rid="CR36">36</xref>
,
<xref ref-type="bibr" rid="CR37">37</xref>
]. A more clear trend is observed when considering solely wild species, where Nagot ethnic group stands alone in one cluster, immigrant ethnic groups stand alone in Sudano-Guinean zone and Otamari linguistic group stand alone too. However, socio-cultural attributes are not sufficient to explain trends revealed by the dendrograms. Villages were mainly clustered according to phytogeographical regions. Camp pionier, a Ditamari village in Sudano-Guinean, does not group with others Ditamari villages in Sudanian region. Bio-geographical factors also play a role in the choice of edible plants by community as also demonstrated for traditional vegetables [
<xref ref-type="bibr" rid="CR24">24</xref>
] and for yams’ varietal diversity [
<xref ref-type="bibr" rid="CR23">23</xref>
] in Benin. We conclude that there is a complementarity between socio-cultural attributes of community and bio-geographical factors that may explain the choice of edible food plants, especially for wild species. This conclusion is consistent with previous results that had shown that the knowledge and consumption of wild edible plants follows a pattern according to ecological conditions of the gathering environments, as well as the cultural heritage of the communities [
<xref ref-type="bibr" rid="CR24">24</xref>
,
<xref ref-type="bibr" rid="CR88">88</xref>
]. Our results also indicated that when a community moved to a more favourable area (e.g. precipitation, soil, plant diversity), members adapted their choice to the plant resources available. Other variables such as distance to markets and urbanization may also affect the choice of edible plants. But, here we are in a context of smallholders farming, and agricultural activities are mainly oriented towards households’ subsistence. Distance to markets and urbanization were not tested in our study areas which are rural settings.</p>

<title>Conclusions</title>
<p>This study revealed the diversity and richness of edible foods plants and analyzed farming practices in arid and semi-arid areas in Benin. We found that wild species play an important role in food consumption of communities in dry areas, and that the diversity of edible plants is higher in the semi-arid area than in the arid one. However, farmers in the less favourable arid area developed advanced resource-conserving practices compared to their counterparts of the favourable semi-arid area. We conclude that if food security has to be addressed, the production and consumption policies must be re-oriented toward the recognition of the place of wild edible plants and farm management practices developed by farmers. For this to happen we suggest a number of policy and strategic decisions as well as research and development actions, including: (1) intensive awareness raising on best farming practices; (2) thorough documentation of wild edible plants and their contribution to household diet; (3) promotion of the ‘’bringing into cultivation” practices; (4) strengthening of livestock-crop integration; and (5) the improvement of agroforestry systems.</p>
<p>There is a room for further investigations on how climatic gradients shape the utilization patterns of crop varietal diversity. This will help develop a sound on-farm conservation approach of plant genetic resources. Moreover, since the frequency of consumption of each species was not documented, more investigations with adapted methodology are therefore required to better understand the importance of each species in the diets. Twenty-Four Hour Recall method (see [
<xref ref-type="bibr" rid="CR58">58</xref>
]) is a useful approach that can help gather information regarding diets and nutritional habits.</p>
