Consumption patterns of wild edibles by the Vasavas: a case study from Gujarat, India



Wild edibles continue to be a significant contributor to the global food basket in much of the developing world. A consensus has now been formed that information on wild edibles is an important part of ethnobotanical knowledge and hence elucidating region-specific patterns of habitat management and consumption assists policy making with regard to natural conservation, human nutrition, and human health. Using an original data set from Gujarat, India, the present research aims to document the collective knowledge of wild edibles possessed by the local Vasava tribe, as well as the habitat usage and consumption trends of these species.


Data were collected using three approaches: key informant interviews to record the local knowledge of wild edibles and methods of collection, village group discussions to quantify past and present consumption trends, and expert interviews to elucidate the reasons for changing consumption patterns.


Through key informant interviews, 90 species of wild edibles from 46 botanical families were identified along with their Vasavi names, plant parts utilized, habitats, and cooking methods. Of these, 60 species were also used medicinally and 15 carried economic value. Different habitats were preferred for collection at different times of the year. Village group discussions unanimously concluded that the consumption of wild edibles has significantly reduced over time. Expert interviews identified the decreased availability of these species in their natural habitats as the most important reason for their reduced consumption.


The present study has demonstrated that the Vasavas’ collective knowledge of wild edibles is vast and that these species contribute to their dietary diversity throughout the year. The finding of the present study, namely that anthropogenically managed habitats were often preferred over natural environments for the collection of wild edibles, suggests that conservation efforts should be extended beyond wild and human-uninhabited landscapes.


Wild plants are a crucial source of food, healthcare, and material subsistence in much of the developing world and carry a strong association with human livelihood [1,2,3,4]. Amongst wild plants, in particular, wild edible plants (WEP), once the most important food source for the human population, along with game food, continue to be significant contributors to the global food basket [5].

The word “wild” in this context refers to species that are not intentionally grown and managed by humans, including those minimally managed to prevent overgrowth or overharvest. This includes both native and alien plants, regardless of the preservation level of the habitats [6, 7].

Many earlier ethnobotanical works focused on lists of useful plants and had a strong tendency to focus on the scouting of new drug sources and new non-wood forest products (NWFP), both of which can be economically lucrative [8,9,10,11,12]. However, in recent years, there has been a growing interest in exploring the traditions of using wild plants beyond material and medicinal purposes and focus on wild edibles, as their roles become better understood in terms of local nutrition [2, 13,14,15], dietary diversity [16, 17], income generation [4, 18,19,20,21], healthcare [22, 23], reduction of micronutrient deficiency [24, 25], and food security through diversification [26,27,28]. There is now a consensus that information on wild edibles, including various modes of utilization and preparation, constitutes an important part of ethnobotanical knowledge and therefore that elucidating region-specific patterns of their habitat management and consumption assists policymaking in the areas of natural conservation, human nutrition, and healthcare [29, 30]. This is particularly the case as a lack of extensive data is one of the major barriers that prevent optimal decision making tailored to local conditions.

There have been efforts to document WEP use traditions in India for a long time; however, due to the extreme diversity of the ethnic population of the Indian subcontinent, as well as its flora, the work is still in its infancy [31,32,33,34,35,36,37,38,39,40,41,42].

The research presented in this paper aims to document the collective knowledge of wild edibles possessed by the local Vasava tribe, as well as the habitat usage and consumption trends of these species. Previous ethnobotanical studies in Gujarat have exclusively focused on economically important species [43, 44], or ethnomedicinal uses [43, 45, 46], so clear knowledge gap exists for the listing and habitat usage with respect to wild edibles.


Study site

Located in the western part of the country, the state of Gujarat is home to 29 Scheduled Tribes that together account for 14.8% of the state population. The Vasavas are one such tribe that have inhabited the Shoolpaneshwar forest belt, one of the dense forest belts within the state (Fig. 1). The medicine men “Bhagats” of Vasava tribe are known for their indigenous plant knowledge to treat illnesses of their community, part of which has recently been recorded from the pharmaceutical perspective [47]. The Vasavas are often described as subsistence farmers who possess traditional knowledge about plants due to close proximity to the forests. Nonetheless, rapid economic growth is inducing outmigration and transformation of land usage in the region, thereby threatening the survival of traditional knowledge as well as free access to forests for this tribe. Even though tribal areas in India often receive intervention programs for nutrition and livelihood enhancement, such programs have never been implemented in the study area, locally known as Dediapada Taluka.

The Shoolpaneshwar forest belt spans an area of 608 km2 over two Talukas, Dediapada and Sagbara, and is considered one of the rich biodiversity zones of the state (Fig. 1). The Narmada district, the administrative unit above them, has a forest cover of 41.5% across an area characterized by hilly terrain and a semi-arid climate. The district’s average annual rainfall is ~ 700 mm, with 31 recorded rainy days (Fig. 2). There are two agricultural seasons, the rainy season (Kharif) from July to October and the post-rainy season (Rabi) from November to March. While all farmers cultivate during Kharif, only those with irrigation facilities plant a second crop during Rabi.

Fig. 2

According to the 2011 district census data for Narmada, 85% of the total population are involved in agricultural production. At the same time, 65% of the total population earn their income as agricultural or industrial laborers, primarily because of small landholding, a phenomenon originating from land fragmentation through inheritance. The majority of the population lie below the poverty line and the literacy rate is low; in Dediapada Taluka, it is 65%. Combined together, these factors force many Vasavas to out-migrate for alternative sources of livelihood, moving them away from their original ecological zone. As their “wisdom” concerning wild plants has typically been passed on from parents to children, limited access to forests by family members is thought to be threatening knowledge transfer.

According to the information collected during fieldwork, the staple source of carbohydrates for the Vasavas is rice while in hilly regions where paddy farming is difficult, it is maize. Other cereals such as sorghum, as well as indigenous millet such as bunti (Echinocloa crus-galli (L.) P.Beauv.), muu (Panicum pilosum Sw), kodri (Paspalum scrobiculatum L.), and bajro (Pennisetum typhoides (Burm.f.) Stapf & C.E.Hubb.), are also consumed, along with cultivated vegetables (both heirloom and commercial varieties) grown in both agricultural fields and home gardens. Wild edibles form a major part of their complementary diet; for example, as much as 40% of the food consumed by the Bhil tribe, who live nearby, was sourced from non-agricultural fields [48], typically collected from nearby forests or their surroundings. For the Vasavas, a typical meal consists of a staple (rice, maize, sorghum, or millet) with vegetables and/or wild edibles, the latter of which are boiled, sautéed, or added to daal (a runny soup made with pulses). Meat, poultry, and fish can also be part of the Vasavas’ diet depending on the family’s economic reach and availability, while dairy products are severely limited due to the lack of storage facilities.

Data collection

In order to achieve the aforementioned aim of the research, local data were collected under three approaches: key informant interviews to record the Vasavas’ knowledge of wild edibles and methods of plant collection, village group interviews to quantify past and current consumption trends, and expert interviews to elucidate reasons for the decreased consumption of wild edibles.

Key informant interviews

Twenty-five key informants from 12 different villages (Fig. 1) were purposefully selected. Altogether, 14 men and 11 women were interviewed. Their ages ranged from 26 to 87 (mean 51.8, median 49). The studied settlements represent all the major ecological features of Dediapada Taluka. These key informants consisted of tribal healers and the local elders, who were considered the most knowledgeable about local plants within each village. Care was taken to include both genders from each village as, generally speaking, more men collect wild plants from forests, while more women are responsible for collecting and cooking plants from the village surroundings (e.g., home gardens) on a regular basis.

The interviews were conducted during the periods of August–September 2016 and December 2016–February 2017. The Gujarati language (the regional language) was used with occasional translation to the Vasavi language (the local tribal language). Each interview started with a field visit with the interviewee, which covered nearby forests, agricultural fields, and swamp habitats where edible plants were growing at the time of the survey. Information on the plant part used, typical recipes for cooking, potential for medicinal use, and the season, and primary locations of collection were noted. Each species was identified and photographically recorded in the field. Voucher specimens were also collected for species not already covered by previous floristic surveys carried out in the region. Following the field visit, each informant was interviewed again, inside their house, where the local names for the plants were confirmed and matched against photographs and dried specimens of the species, under the supervision of an experienced local taxonomist. The dried herbarium specimens of the species are identified by a taxonomist and stored at the herbarium of The Serenity Library & Botanical Garden (for details, refer to “Availability of data and materials”).At the conclusion of all interviews, a comprehensive list of wild edibles utilized by the Vasavas was compiled. This list was subsequently used to analyze habitat distribution and seasonal consumption patterns, as described below in the “Data analysis” section.

Village group discussions

Village heads, local school officials, and long-term residents from 12 villages (96 respondents) were invited to group discussions, held in August–September 2016, about the past and current trends surrounding the consumption of wild edibles. These open-ended interviews were carried out at either village schools or the homes of village heads/key informants. When the snowball technique was employed to maximize the amount of information collected, care was taken to include participants of various age groups from both genders.

Expert interviews

Structured questionnaire surveys were conducted with seven experts from different villages (Bondiservan, Vadhwa, Khudadi, Khokhraumar, Zadoli, Khairdipada, and Jamni villages), who were selected based on the recommendation of village heads during the group discussions. The questionnaire was based on the input obtained from the village group discussions and designed as a multi-purpose survey. The results presented in this paper primarily focus on the reasons for changing consumption patterns of wild edibles, obtained by means of pairwise comparisons [23, 49], encompassing six alternatives. The scores derived for each reason were aggregated across seven experts, producing an overall score that can take any value between 0 and 35.

Data analysis

Categorization of species

Each species included in the plant list (prepared from key informant interviews) was categorized into one of five groups based on its habit (trees, shrubs, herbs, twiners, climbers), and one of the seven groups based on the habitat from which it was primarily collected (village, forest, swamp, village and forest, swamp and forest, village and swamp, all three locations). Here, a village habitat was defined as an environment that was fully or partially anthropologically managed (Fig. 3a–c). A forest habitat was defined as an area minimally managed by humans (although they are often close to villages), and a swamp habitat as a location where water bodies were present for most of the year, for example puddles, small riverines, and ponds. This grouping was based on the most common habitats from which each species was collected and therefore does not imply non-presence of the species in other locations.

Fig. 3

ac Representative habitats for wild edibles: a village habitat, b forest habitat, and c swamp habitat

The parts of the plants utilized were also categorized into six groups (leaves, flowers, seeds/fruits, underground parts, young shoots, multiple parts). The fourth group (underground parts) represents all storage organs including tubers, bulbs, corms, and rhizomes. The last group (multiple parts) covers species that are primarily collected for non-edible purposes but of which organs (same or different) are also used as human food.

Local names for plants in the compiled species list were transcribed into English with phonetic intuition, as the Vasavi language does not have a written script. Typical months of collection and typical methods of cooking were also recorded in this list, so as to obtain insight into the Vasavas’ culinary outlook and nutritional status.

A complete plant list was compiled with their Vasavi names, scientific names, plant parts utilized, primary habitats, and cooking methods. This aggregated information was further used for analyzing the consumption and collection patterns as described in the “Results” section.

Consumption and collection patterns

Following the compilation of the species list, the number of species collected from each habitat category was quantified. This value was used as an indicator for the seasonal availability of the plants and for the locations of actual collection events [50]. Since the primary focus of the present study was on usage patterns of habitats for sourcing these species, the number of species was judged to offer better insights than the level of biomass available, a common indicator for sustainable harvesting. The number of species collected for each plant part was also collated to evaluate the potential of wild edibles to provide diverse pathways of nutrient acquisition. The information collected from the village group discussions and the expert interviews was utilized to support interpretation of the quantitative findings.


Through the key informant interviews, 90 species of wild edibles were identified (Table 1). These species belonged to 46 different botanical families; the families with the most number of species represented were Amaranthaceae (6 spp.), followed by Asclepiadaceae (5 spp.) and Dioscoreaceae (5 spp.). All Amaranthaceae species were collected for their leaves, while all Dioscoreaceae species for their aerial tubers. The family Asclepiadaceae had a more diverse pattern of plant utilization, with leaves, tubers, and fruits all used for cooking. Some of these species were used for medicinal purposes as well.

Table 1 List of wild edible species used by the Vasavas

The average number of wild edible species mentioned by a key informant was 48.4 (median 51). The average number of wild edible species collected for fruits mentioned was 13.6 (median 13), for leaves was 14.5 (median 14), flowers 3.4 (median 3), tubers 5.1 (Median 5), and young shoots 2.1 (median 2), and average wild edibles with multiple uses mentioned was 9.5 (median 9).

The Vasavas were found to prefer leafy greens either stir-fried or boiled and to consume them in combination with other distinct-tasting (sour or bitter) leafy greens and crushed chilies. Tubers, leaves, and shoots were sometimes boiled and then blended with yoghurt or buttermilk to weaken the mucilage. The use of oil and spices other than salt and chilies in their recipes was minimal. Fruits were often collected recreationally and sometimes pickled and preserved.

A comparison of the compiled list against a preceding list of ethnomedicinal plants from the study area [47] suggested that 60 out of the 90 wild edibles identified are also medicinally used by the Vasavas (Table 2). A further comparison of the list against the Gujarat State Forest Development Corporation’s (GSFDC) NWFP collection revealed that 15 out of the 90 species also carry economic values when sold to GSFDC (Table 3).

Figure 4 represents the Euler proportional distribution [51] for the locations of collection. The largest number of species (37) was collected from village habitats only, followed by the groups only collected from forest habitats (20 spp.), and from both village and forest habitats (20 spp.). Six species were collected only from swamp habitats, while two species were collected from both villages and swamp habitats. Five species showed no habitat preference, collected at all three location groups. Three of these species were from the genus Amaranthus, and one species each was from genera Commelina and Ipomea.

Different habitats were preferred for collection at different times of the year. Village habitats were extensively used during the months of March and July (Fig. 5). These periods are marked, respectively, with the onset of summer and the beginning of the Kharif cropping season. Forests were most utilized in August (9 spp.) and least utilized in December, the latter of which coincides with dry winter and was generally the least active month for collection across all habitats. Swamps were used more regularly across the year, with 5–6 species collected at any given time.

Fig. 5

Collection patterns by habitat overlaid with monthly precipitation

A large number of tree species were collected from village habitats between January and June, while more herb species were collected from June to December (Fig. 6). The number of tree species collected from forest habitats was relatively constant across seasons, whereas collection of herb and shrub species in forests was more frequent between June and September. The numbers of herb, shrub, and climber species from swamp habitats remained constant throughout the year. For species collected from both villages and forests, collection of shrub species increased between May and December, while tree species were mainly collected from January to July. Across all habitats, the collection of herb species increased during the months of May to September.

Fig. 6

Collection patterns by habitat and plant type

Seasonal consumption patterns for each plant part are shown in Fig. 7. Twenty species of leafy vegetables were collected during the monsoon season of June to September, while seeds and fruits were collected, probably to supplement the diet during the dry and hot summer period, between February and May.

Fig. 7

Collection patterns by plant part utilization overlaid with monthly precipitation

Of the species originating from village habitats, leafy species dominate from June to November (Fig. 8). In contrast, more fruits and seeds were utilized during the dry period of January to May. Utilization of forests as a source of leafy vegetables was negligible; species collected for multiple parts dominated these habitats, followed by fruits and seeds mainly collected from January to May. The number of leafy species harvested from both village and forest habitats was highest from June to October. No tubers were exclusively sourced from forests; they were rather collected from combined village and forest habitats. Young shoots were collected from forest habitats from July to October and then from village habitats from January to May. Across all habitats, the number of leafy species collected increased between June and November.

Fig. 8

Collection patterns by habitat and plant part utilization

The majority of fruits in the Vasavas’ diet were contributed by tree species (Table 4), while leafy vegetables were mostly sourced from herb and shrub species. Trees were mainly utilized as edible fruits or for multiple parts (refer to the “Categorization of species” section), shrubs for multiple parts, and herbs for leaves. The main sources of tubers were twiners, and edible flowers were mainly sourced from trees, shrubs, and herbs.

Table 4 Number of species by habit and plant part utilization

As previously mentioned, village group discussions were open-ended, guided towards conversations about the consumption patterns of wild edibles past and present. When asked whether consumption and utilization of wild edibles had increased, decreased, or remained unchanged since as distant a past as they could remember, all respondents unanimously stated that their consumption had decreased, a response subsequently repeated in the expert interviews as well. Participants in group discussions highlighted several reasons for this change, for example the inability of children to identify species and participate in their collection, and their preference for cultivated vegetables. Comments were also made that the availability of certain species had decreased in their respective habitats, and thus, villagers would need to travel further into the forest to collect a sufficient amount.

These answers were then used to design a section of the questionnaire for the expert interviews, in which they were asked to rank pairwise the predefined reasons for decreased consumption of wild edibles. The most common reason, ranked on the total score of 7 respondents, was decreased availability, followed by a change in food preferences and the lack of the knowledge needed to identify species (Table 5). The respondents also indicated that there was an increasing preference for cultivated edibles amongst the younger generation, who have insufficient time to go out and collect wild edibles, due to their work and household commitments. The lowest ranked reason was a reduced requirement for a safety net for times of need, such as famines and financial shortfalls.

Table 5 Pairwise ranking for the cause of decreased consumption of wild edibles


All-year sustenance from wild edibles

In this research, 90 species of wild edibles from 46 botanical families were identified as used by the Vasavas in Dediapada Taluka. This is a high number of species compared to other studies previously undertaken in India: 61 species from Maharashtra located near Gujarat [52] and 22 species from the deciduous forests of Chhattisgarh in Central India [53]. From the northeastern state of Manipur, there were reports of 32 wild edibles by Pfoze et al. [15] and 68 species by Thongam et al. [54]. As for leafy vegetable plants, 24 species were identified in the present study, which is comparable to 21 species reported from Uttarakhand by Misra et al. [2].

To compare our results to other parts of Asia, 45 WEP species were recorded from the Lesser Himalayas in Pakistan [23], 87 and 252 from Thailand [50], 90 from the Mekong Delta region of Vietnam [22], 54 and 81 from Tibetan communities of the eastern part of the Tibetan Plateau [55, 56], and 185 (including 126 species of wild vegetables) from the Chinese (Han) [57]. Zou et al. [58] recorded more, noting the use of 335 taxa of wild vegetables in 10 villages of Hunan, China, whereas Ghorbani et al. [59] recorded the use of 173 wild food plants from 485 informants of four ethnic groups of the Naban valley of Xishuangbanna (a tropical area of south China), the latter being very heterogeneous in terms of elevation, inhabitants, and vegetation. To sum up, the numbers of WEPs recorded in India, Pakistan, and on the Tibetan Plateau are comparable with our results, apart from parts of Thailand and China, where the local communities use much longer lists of WEPs. The numbers of wild foods recorded in the studied community are also similar to those found in the Mediterranean countries, e.g., 82 wild food species as reported by Dolina and Luczaj [60].

The species that have been the first reports from this area for their edible purpose are Ceropegia fantastica Sed and Clematis hedysarifolia DC.

The fact that wild vegetables are collected all year round (partly due to access to swampy habitats) is quite unique. In most of the papers dealing with wild foods, the times of gathering are usually mentioned as the “rainy season” [61] spring and early summer [57] or spring and autumn [62].

Anthropogenically managed habitats for wild edible collection

Anthropogenically managed habitats (e.g., villages, 37 spp.) were preferred to unmanaged habitats (e.g., forests, 20 spp.) for the collection of wild edibles (Fig. 4). This result is counter-intuitive given the term “wild,” which is more generally associated with unmanaged environments. A similar observation was made by Cruz-Garcia and Price [50] and Misra et al. [2], in whose research man-made agro-ecosystems were found to be an important source of wild edibles. Combined with the number of species collected from both forest and village habitats (20), a total of 57 species were collected from anthropogenically managed habitats; this suggests that conservation efforts for wild edibles should be extended beyond natural forests, as human-inhabited areas also constitute important habitats for the community. Their occurrence is intertwined with traditional crop cultivation, forming agro-ecosystems providing both cultivated and wild economic plants [7].

While tree species from forests were collected all year round, their collection from villages was largely limited to the first half of the year, when only households with irrigation facilities can cultivate crops (Fig. 6). These tree species, therefore, are thought to be a vital, and possibly the only, source of micronutrients for a large proportion of the Vasavas, especially during the hot and dry summer.

Swamps were shown to be important habitats for leafy vegetables throughout the year (Fig. 8). While a large number of species were sourced from these habitats during the monsoon and post-monsoon seasons, their availability in villages and forests was negligible during summer. Hence, the maintenance of swamps and water bodies is likely to be crucial for the year-round inclusion of wild leafy vegetables in the diet.

The role of wild edibles in dietary diversity

Boedecker et al. [16] showed that the consumption of wild edibles was significantly related to an increased level of dietary diversity, which, in turn, has been associated with nutritional quality and therefore is a useful indicator for food security [63, 64]. It is thus likely that the consumption of wild edibles would improve the nutritional status of the tribal population, who have limited access to anthropogenically produced plants. In the present case, the largest number of species belonged to fruits category, followed by leafy vegetables (Table 1). This finding suggests that the Vasavas enjoy a diverse supply of micronutrients, as many of them are abundant in plants that come under these two categories [14].

A FAO case study carried out in Gujarat reported that, for the Bhil tribe, wild foods contributed 30% of total energy intake for children and 24% for pregnant women. Furthermore, 41% (39 of 95 items) of their foods were collected from uncultivated sources, showing a high dependence on wild edibles for both energy and micronutrients [48]. While a detailed nutritional investigation is beyond the remit of the present study, the above results indicated that the Vasavas are highly dependent on wild edibles as well, especially for micronutrients from fruits and leafy vegetables.

Wild leafy vegetables are an important source of carotenoids, including vitamin A [65]. Provided the leaves are consumed with fats, they can provide a year-round supply of vitamin A, as is the case of this tribe, where it is noted that they consume leafy vegetables that are stir-fried in vegetable oil [66].

Healthcare implications

A comparative analysis between the present data and a previous ethnobotanical investigation focusing on medicinal plant usage (Table 2) revealed that 67% of edible species could also be used for medicinal purposes. This shows a great overlap of the food and healthcare functions of wild plants, as has been reported elsewhere [22, 53]. Although it is difficult to quantify the health impact associated with the regular consumption of medicinal wild edibles, their inclusion in the daily diet at least ensures the maintenance of traditional medicinal knowledge through continued usage. The level of traditional medical knowledge has been rapidly declining in various parts of the world [67,68,69]; in the case of India, where medical pluralism is a long-standing cultural phenomenon [70], wild plants offer an important alternative to modern allopathic healthcare options, which are expensive and less accessible in many rural areas [70].

A study of the adolescent tribal population from nine states in India, including Gujarat, reported that amongst tribal people, deficiency in micronutrients, such as vitamin A, iron, free folic acid, and riboflavin, was more severe than that in energy and protein [71]. The same trend was also observed on the study site by a local allopathic doctor, who attested that vitamin B and iron deficiency (including genetic sickle cell anemia) were extremely common in the region. Given that leafy vegetables are widely recognized as a rich source of vitamin A, vitamin B complex, and iron and that cultivated greens as well as meat and dairy products are limited in the local market, wild leafy vegetables are a crucial source of these micronutrients [65]. A similar argument also holds for wild fruits, which are considered to be a good source of micronutrients and fibers, as nutritional studies of indigenous food from Jharkhand, India, indicate [72, 73]. Considering the relatively low cost associated with the acquisition of wild edibles compared to foods of equal nutritional value available on the commercial market, encouraging their continued consumption is likely to be a reasonable choice.

Decreased consumption

It was found that the primary reasons for decreased consumption of wild edibles were their decreased availability, changes in food preferences, and a lack of the knowledge needed to identify edible species (Table 2). The second and third reasons are somewhat interrelated, as changes in food preferences over a prolonged period of time may have exacerbated the lack of knowledge of species which are no longer familiar. Similar situations have been reported in the literature, where formal schooling [74] and lack of access to forests [67] led to a decline in traditional ecological knowledge and individual knowledge of medicinal plants.

The primary reason behind the preference for cultivated vegetables is thought to be a gradual shift in diet. For example, young children attending a school outside their village become acquainted with wheat and cultivated vegetables and at the same time have fewer opportunities to visit forests with those who can share their knowledge of edible (and medicinal) plants. This trend may potentially be reversed by, amongst other methods, maintaining children’s contacts with wild edibles when they return home for holidays and modifying the education curriculum to cover more knowledge from within the region [75, 76].

Unlike other studies reporting “stigma” against wild edibles amongst tribal people in India [69], such a perception was not observed during the present study. The results from the expert interviews indicate that the Vasavas do not generally collect wild edibles as an economic safety net, the leading mechanism to produce “stigma” [69]; instead, the most cited reason for the decreased consumption of wild edibles was simply decreased availability. It is interesting to note that, while most families in the study region are still engaging in collection, most respondents at both the village group discussions and the expert interviews expressed the view that the overall consumption had significantly decreased. A similar finding was also reported from the Nanda Devi biosphere reserve in India by Misra et al. [2]. This phenomenon warrants further analysis, possibly through quantitative evaluation of biomass availability across habitats and seasons.

Promotion of wild edibles

Reyes-Garcia et al. reported that association of “cultural ecosystem services and values” explains the change in consumption patterns of wild edibles and that there had been a revival of certain wild species that were associated with “traditional” foods [68]. In other words, gastronomic culture could help maintain the consumption of certain wild edible plants. This is an important point to consider at the designing stage of intervention programs for conservation of traditional knowledge or dietary diversity. Associating cultural identity with wild edibles will likely maintain the familiarity of these plants and, by extension, promote their usage amongst younger generations. Examples of these efforts include community-based activities, such as recipe competitions and food tasting at village fairs, or workshops at schools and social gatherings.


The present study has demonstrated that the Vasava tribe’s collective knowledge of wild edibles is vast and, more importantly, significantly contributes to dietary diversity throughout the year. The finding of the present study, namely that anthropologically managed habitats were preferred over natural environments for the collection of wild edibles, suggests that conservation efforts should be extended to village landscapes in addition to human-uninhabited landscapes. Of a wide range of wild edibles, tree species are likely playing an especially important role in the acquisition of micronutrients, as they can provide sustenance throughout the dry period. While there is no doubt that inclusion of these species in future development planning is important, pathways to ensure the spontaneous consumption of wild edibles need to be further developed at the same time. Continued consumption will likely maintain knowledge within the community and, through a spillover effect, along with the medicinal and industrial values attached to the species.
