Abstract
Ethnobotany is defined as the study of the traditional botanical knowledge of different cultures, the techniques utilized in the use and management of plant resources, and the place they have in their cultural Cosmo vision. This study aimed to review the development and perspectives of ethnobotany in Mexico, based on an extensive review of all ethnobotanical studies showed at the Mexican Botanical Congress (MBC), the main forum of ethnobotanical studies in Mexico, between 1963 and 2010. We systematized a total of 897 works, identifying their progressive increase in the generation of investigative papers up until 1990, then a decrease until 1995 and a new increase from 1995 to the present. The main Mexican institutions studying ethnobotany are the Universidad Nacional Autónoma de México, Universidad Autonóma Chapingo, Instituto Politécnico Nacional, Universidad Autónoma Metropolitana, and the Universidad Autónoma de Nuevo León, which produced nearly half of all the studies recorded. The best represented cultural groups studied were the Maya, Nahua, Otomí, Totonac, and Mixtec, studied under the predominant approach of descriptive ethnobotany. Ethnobotany in Mexico is in a stage of growth and therefore in the phase of consolidating its approaches, particularly in the areas of ecological, economic, quantitative, and evolutionary ethnobotany. In order to achieve the development of sustainable management strategies of plant resources, it is of the highest priority to consolidate ethnobotanical research and direct it towards the analysis of environmental degradation and solutions.

Introduction
As a scientific discipline, ethnobotany emerged as a result of the co-evolution of botany and anthropology throughout the eighteenth and nineteenth centuries. It was, however, in the twentieth century when it became a consolidated study field with unique methods. Harshberger [1] first coined the term ethnobotany and defined its domain as “… the study of the interrelationships of primitive man with plants.” In the 1930s, interest in economically important species introduced the term “economic botany,” which made explicit the interest in linking ethnobotanical research and the prospective of new materials for industry. Oakes [2], for instance, defined economic botany as “… the link between anthropology and industry derived from plants.” In contrast, for anthropologists of that time, plants and animals were elements with important cultural significance, and through the study of such significance, anthropologists constructed the early ethnobiological approaches. The anthropologist Maldonado-Köerdell [3] defined ethnobiology as “… responsible for the study of plants and animals, in any region, defined by a human group that inhabits or habituates a region to get them … essentially a cultural science.” In the 1940s, ethnobiological research gained status as a discipline focused on the knowledge of plants and animals between different people. Particularly, Schultes [4] defined ethnobotany as an intermediary between botany and anthropology, whose purpose is “…the study of the relationship between humans and their plant environment…”. Similarly, Jones [5] defined ethnobotany as the field of study specifically aimed at analyzing the relationship between humans and plants.
These basic concepts have prevailed in subsequent decades, but several authors have incorporated different emphases to definitions according to their perspectives. For example, Bye [6] defines ethnobotany as “… the study of the biological basis of the interactions and plant-human relationships at different levels of organization (ecosystems, communities, individuals) in a geographical, social and evolutionary scale.”
Because of the momentum of the ethnobotanical movement, particularly since the 1960s and early 1970s, different research approaches in the field have been developing in Mexico to the present day. This process was reinforced by the recognition of ethnobotany as a scientific discipline, which has been strengthened with robust methodological frameworks and depuration of the field [7–11]. By the 1970s, Latin American ethnobotany succeeded in developing a critique of the folklorist and utilitarian approaches developed mainly by some researchers from the U.S. and Europe. As part of this critique, Hernández-Xolocotzi [7] recognized the interdisciplinary nature of ethnobotany and the importance of “…the collaboration of institutes, professionals interested and trained in accordance with the inherent problems of collection, propagation and conservation.” At the end of that decade, Barrera [12] defined ethnobotany as “…an interdisciplinary field that includes the study and interpretation of knowledge, cultural significance, management and traditional uses of the elements of flora”; a concept in which Hernández-Xolocotzi [13] included the dimensions of time and space “… over time and in different environments.”
Currently, ethnobotany is a scientific discipline that documents, analyzes, and looks for understanding the botanical knowledge possessed by different cultural groups that inhabit the planet, the beliefs and cosmo vision in relation to the plant world around them, and interactions and practices established with plants to take advantage of their benefits. Such knowledge, beliefs, interactions, and practices are those concepts that Toledo [14] and Berkes [15] have called and defined as “corpus,” “kosmos,” and “praxis,” respectively. These cultural elements have been the result of the development of specific human cultures in time and space and have been passed from generation to generation in oral or written form.
The main interest of this chapter is to provide a perspective about the state of ethnobotanical research in Mexico. For this task, we analyze the main approaches of ethnobotany that drive the development of this field of study in Mexico, and the perspectives, priorities, and strategies necessary to strengthen this area of research in relationship with various sectors of society.
Ethnobotanical Research, a General Overview
Numerous studies have documented traditional ethnobotanical knowledge in Mexico. These include not only utilitarian aspects of the properties of plants, but also aspects such as (a) forms and functions of their component structures, (b) life cycle, (c) behavior in relation to environmental changes (e.g., seasonality in the production of leaves, flowers, fruits, and seeds) [16–18], (d) the vulnerability or resilience to interactions with herbivores and/or competitors or to human activities (burning, logging, and other forms of disturbance) [18–22]. Traditional botanical knowledge (TBK) also includes ecological aspects like distribution and abundance of plants in specific environments, the interactions with other living beings (herbivores, frugivores, bird species that nest in them, species of insects whose larvae feed on their tissues, among others). Such knowledge can be comprehensive and is often used as criteria for classification of plant species or variants in scientific studies; see examples in [23–26], as well as for the development of management strategies [19, 21, 22, 27–30].
TBK of plants has practical application in management techniques that shape human interaction with plant populations and communities and can be classified in different types. The first type is the extraction or harvesting of useful parts of the plants. Of the estimated 5000–7000 of plant species that are currently used by traditional people in Mexico [18], about 90 % are obtained by this kind of interaction [24]. Some ethnobotanical studies have characterized various forms of collection, including those involving community agreements to rotate and protect areas, as well as occasional vs. intensive practices [21, 22, 31, 32]. Furthermore, several studies [19, 33, 34] suggest that extractive techniques may control such factors as size, structure, and population dynamics to ensure and increase the availability of certain plant resources.
A second type of interactions between humans and plants is formed by different silvicultural forms of management . We have generally identified: (a) tolerance, which involves leaving individuals of favorable species when vegetation is purposefully disturbed, (b) promotion or encouragement of favorable species, which involves activities aimed at increasing the population density of favorable species, (c) protection, including control of herbivores, thinning of competing plants, performing pruning and other forms of protection of plants representing some utilitarian advantage for humans in natural vegetation areas subjected to deliberate disturbance, and (d) sowing and transplantation of propagules (sexual or vegetative) or complete individuals from wild environments to humans-controlled environments (such as agricultural plots, orchards, or home gardens) [19, 35–38]. In Mexico, about 700 species of plants have been documented that are subject to some of these types of silvicultural management [28]. However, this figure is likely an underestimate; for example, only in Tehuacán-Cuicatlán Valley, Blancas et al. [39] reported about 600 species under these forms of management.
Silvicultural management has been distinguished from agricultural management [19, 27]. Agriculture constitutes the third general type of interaction between humans and plants. At this level, there are great diversity of species and varieties of plants under traditional management, with a high diversity of agricultural hydraulic and intensive systems (including irrigation systems, raised or drained fields systems, and terraces systems), seasonal and semi-intensive and extensive systems (including high diversity of rain-fed systems and slash-and-burn, shifting or swidden agriculture), as well as homegardens, and agroforests combining wild and domesticated plants (e.g., cocoa, coffee, and pineapple plantations and a wide variety of types of milpa in association with elements of forests) [18, 40–42]. Traditional agriculture may involve management of varieties resulting from modern breeding processes used in intensive agricultural systems.
Mexico is one of the countries on the world with the highest biological and cultural diversities [43–45]. However, one of Mexicans’ major concerns is the gradual loss of these diversities, including the threatening processes occurring on species at the community and ecosystems levels, as well as intra-specific variability at population level. These processes of loss are the result of multiple factors influencing the transformation of natural ecosystems and complex processes of causing cultural change [46], which induce the transformation of traditional management systems [42, 47, 48]. Against this backdrop, several authors have considered that for the world today, conservation and construction of sustainable management strategies of natural resources and ecosystems are of high priority. It is also widely recognized that traditional knowledge is particularly important to these goals in the understanding, respect, use, and even improvement of local knowledge and practices to protect global patrimony [15, 47, 49]. This posture recognizes that the traditional forms of natural resource use possess traits of sustainability that must be understood and managed. It also recognizes complexity of the socio-ecological systems in which they are embedded as well as the complex processes of resource utilization that require the inclusion of human experience in the broadest sense, as well as the ongoing evaluation of successes and failures and consequent adjustments. This is the notion of adaptive management, which recognizes that the complexity of socio-ecological systems requires continuous construction, monitoring, and adjustment (adaptation) of intervention strategies of natural resources and ecosystems.
Ethnobiological studies are a window to the understanding of traditional knowledge and practices of management of biotic resources and are, therefore, crucial for technological innovation for the sustainable use of resources and environmental problems resolution. In recent decades, these goals have become increasingly explicit in ethnobiological research, particularly those research approaches that include ecological methods [26, 50–52].
Approaches to Ethnobotanical Research
Miguel Ángel Martínez-Alfaro [53], an outstanding Mexican ethnobotanist, characterized eight general lines of ethnobotanical research: (1) archaeobotany, (2) medicinal plants, (3) edible plants, (4) cognitive studies, (5) forest management, (6) agroforestry systems and orchards, (7) domestication and the origin of agriculture, and (8) historical studies. These perspectives reflect the research fields of ethnobotany, but also they are constructed from particular theoretical frameworks. In this sense, Martínez-Alfaro [53] recognizes that the research approaches referred to above are developed under various disciplines such as taxonomy, plant ecology, plant geography, plant physiology, floristic, among others. Based on the thinking of Martínez-Alfaro [53], in this study we recognize six major areas of theoretical construction of ethnobotany:
-
1.
Descriptive ethnobotany . This approach primarily focuses on constructing listings and catalogs of plants along with their uses and traditional nomenclature.
-
2.
Cultural ethnobotany . This perspective includes studies that analyze historical aspects of the use of plants, their cultural significance, traditional classification systems (folk classifications), linguistic analysis, processes of acculturation, and intra-cultural variation of plant use and knowledge. We also consider within this approach those studies pertaining to knowledge and traditional perception of plant resources and ecosystems, as well as studies that look for understanding the cultural significance and implications of classifications of plants and ecosystems where they occur.
-
3.
Economic ethnobotany . This approach focuses on the economic valuation and marketing of plants (market research and exchange), the commercial and industrial potential of crops and wild plants (phytochemical analyzes, bioprospecting), processes (experimental propagation techniques of crops, among others), analyses of performance, cost–benefit balance, and studies evaluating the role of plants in peasant subsistence.
-
4.
Ecological ethnobotany . This research perspective focuses predominantly on studies that analyze the spatial distribution, abundance, seasonal availability of plant resources, phenological studies, demographic and synecological research, as well as impact assessment for management techniques of populations of useful plants, their communities, and ecosystems. We also included studies aimed at characterizing and evaluating functional aspects of traditional management systems. In this approach, the ecological bases of the use of plant resources and the implications for conservation and sustainable management from the perspective of the ecology of populations, communities, ecosystems, and/or landscape are emphasized.
-
5.
Evolutionary ethnobotany . This approach focuses on studies that analyze the evolutionary implications of plant management. We included researches documenting morphological variability and population genetics, physiological and reproductive variations in wild and managed plants with the goal of understanding the current processes of domestication. Archaeological, systematic, and phylogeographic studies were also included that provide understanding with regard to the evolutionary history of these processes associated with human–plant management, its origin and diffusion.
-
6.
Theoretical ethnobotany . We included those researches that make reflection and construct theories on the ethnobotanical research as a scientific discipline. These studies generally review the development of ethnobotanical research and aspire to define and steer the course of ethnobotany. Our analysis in this chapter exemplifies this research approach.
Approaches to the State of Ethnobotanical Research in Mexico
One of the interests of the present study is to provide a perspective on the state of ethnobotanical research in Mexico. This preliminary outlook is based on the review of the abstracts of the ethnobotanical studies showed in the meetings of the Mexican Congress of Botany (MCB) from 1960 to 2010 (Table 2.1). The works presented at these congresses (including lectures, oral presentations, posters, symposia, workshops, and conferences) were considered as a primary and the most representative source of information on the ethnobotanical studies carried out in Mexico during the period referred to. It is important to clarify that the MCB is divided into thematic areas within which ethnobotany and economic botany were the primary scopes of systematization of the analyzed works. With the information obtained, we constructed a database that included: (1) the institutions at which the authors of the work presented were affiliated, (2) the locations in Mexico where the ethnobotanical research was accomplished, (3) the cultural groups studied, and (4) the theoretical framework of the ethnobotanical work analyzed.
We recorded a total of 897 ethnobotanical works presented in 18 sessions of MCB between 1960 and 2010. Figure 2.1 shows a trend of progressive increase in the production of ethnobotanical works, which reach a peak in 1990 and then a drastic decrease. Such marked decline in the production of ethnobotanical works presented at the MCB was influenced by the Ejército Zapatista de Liberación Nacional uprising, which represented the starting point for the visibility and momentum of contemporary peasant and indigenous movements [54] to which ethnobotanists were particularly receptive in the academic sector. From 1995 to 2001, there was an increasing trend in the number of ethnobotanical papers presented at the MCB. Then the number of works descends again and appears to gradually recover by 2010.
A total of 116 institutions participated with ethnobotanical studies over the history of MCB, among them 70 are Mexican (66 %) and 19 are foreign (18 %) educational and research institutions, 11 government agencies (10 %), and 6 NGOs and social organizations (6 %). The ethnobotanical works reviewed in this chapter constitute a sample of the studies carried out in Mexico and mostly done by Mexican researchers and research institutions. However, Martínez-Alfaro [53] estimated that about 50 % of ethnobotanical studies in Mexico are carried out by foreigners, so this bias must be considered in the data presented here. This information indicates that non-Mexican researchers and institutions developing ethnobotanical research do not regularly attend the MCB.
Among the most relevant institutions contributing with ethnobotanical works, we found the Universidad Nacional Autónoma de México (UNAM) with 244 studies over the period analyzed (26 %), the Universidad Autónoma Chapingo (UACh) with 81 (9 %), the Instituto Politécnico Nacional (IPN) with 63 (7 %), the Unversidad Autónoma Metropolitana (UAM) with 52 (6 %), and the Universidad Autónoma de Nuevo León (UANL) with 30 (3 %) (Fig. 2.2). About 50 % of the works presented at the MCB were produced by these five institutions located in different cities of Mexico. Other universities with significant contributions are: Universidad Autónoma de Yucatán, UADY (22 works), Universidad Autónoma del Estado de Morelos, UAEM (21 works), Universidad de Guadalajara, U de G (20 works), Universidad Veracruzana, UV (19 works), Benemérita Universidad Autónoma de Puebla, BUAP (17 works), Centro de Investigación Científica de Yucatán, CICY (15 works), and the Universidad Autónoma del Estado de Hidalgo, UAEH (14 works).
It appears that not all the Mexican institutions carrying out elatterthnobotanical studies are well-represented in the MCB. These are, for instance, the cases of the Instituto Tecnológico del Valle de Oaxaca, ITVO (with 4 works) and the Colegio de la Frontera Sur, ECOSUR (with 3 works), which have recognized research groups in the area of ethnobotany and ethnobiology, and are poorly represented in the MCB.
Of the 31 states that make up the Mexican nation, there has been at least one ethnobotanical study in 30 of them. The states with the highest number of studies are: Puebla (102 works), Oaxaca (70 works), Veracruz (53 works), Yucatán (43 works), Morelos (34 works), Guerrero (31 works), Tabasco (28 works), State of Mexico (26 works), and Hidalgo (26 works) (Fig. 2.3). The states that showed the lowest number of studies were: Guanajuato (2 works), Sinaloa (2 works), and Nayarit (without any studies recorded in the MCB). This fact is important to highlight because the ethnobotanical research group of the Facultad de Ciencias (UNAM) has developed research projects particularly in this latter state, which is not reported in the works reviewed.
The revised works include a total of 42 indigenous cultures, including studies on the Quechua in Peru and the Kekchi in Guatemala. Indigenous cultures best represented were the Maya (39 works) (Fig. 2.4) followed by the Nahua (33 works), Mixtec (21 works), Otomí (20 works), Totonac (18 works), and the Zapotec (12 works). Indigenous cultures underrepresented (only one registered study each) are the Chol, Huichol, Ixcatec, Matlatzinca Mayo, Pima, Seri, Tlapanec, Tlaxcaltec, Tzeltal, and Yaqui. Nearly 74 % of the abstracts made no reference to any indigenous cultures in particular, which is apparently because the studies were conducted with Mestizo people.
Table 2.2 shows the total number of studies recorded in the Ethnoecological Atlas database [46, 55] relative to those recorded in the MCB and takes into account the most represented original cultures. Although the Ethnoecological Atlas includes information from different fields of knowledge (not just from the ethnobotanical perspective), the Maya, Nahua, Mixtec, Totonac, and Otomí are also the best represented, which is consistent with findings in our MCB sample. To date, there have been studies on 40 of the 68 indigenous groups [56], and 56 % of the total have focused on only five of them. From the perspective of the two sources of information, the need for more ethnobotanical studies including a greater number of the Mexican original groups is clear.
In the 1960s, the studies focused on economic ethnobotany and ecological ethnobotany approaches dominated the ethnobotanical research in Mexico. Only these two approaches covered 28.6 % (6 works) and 47.6 % (10 works), respectively, of the papers presented in the 1963 MCB (Table 2.3). In that decade, the studies covering descriptive ethnobotanical approaches, cultural ethnobotany, evolutionary ethnobotany, and theoretical ethnobotany were scarce (Table 2.3). However, from the 1970s, there has been a gradual increase in the number of ethnobotanical work using the different approaches considered in this analysis. The proportion of research with a descriptive approach went up in the late 1970s becoming the predominant approach at the MCB (29 papers on average per conference) followed by economic ethnobotany (18 papers), cultural ethnobotany (17 papers), ecological ethnobotany (16 papers), evolutionary ethnobotany (3 papers), and theoretical ethnobotany (3 papers on average per conference) (Table 2.3). It is noteworthy that, since 1990, there has been a trend toward presenting a more even proportion of the papers pertinent to the different ethnobotany research approaches at MCB conferences.
The scope of the analysis presented here represents only a sample of the ethnobotanical production in Mexico mainly by Mexicans and not all the research generated either by national or foreign educational and research institutions. Moreover, understanding the interests and motivations of the ethnobotanical research in Mexico is incomplete from the characterization of the theoretical approaches that we have made. We recognize that a limitation of our analysis is the review of only the abstracts of works presented at the MCB (which is the information available in the reports of the congresses that were reviewed) and also that we identified that other research areas developing etnobotanical studies (for instance, anthropologists) are not well-represented in the MCB. Therefore, to have a more complete picture of the development of ethnobotany in Mexico is necessary to expand the sources of analysis (including theses, scientific articles, books, interviews, among others). However, the trends and proportions identified based on this source allow identifying the heterogeneity of the development of the research approaches and those cultural groups and ecological regions that need to be studied.
Ethnobotanical Research Perspectives in Mexico
Ethnobotany currently faces challenges that lie beyond the scientific activity and encourages reflection on the academic work of ethnobotanists. In the twenty-first century, ethnobotany has a wide range of applications and roles in society that easily exceed the scientist work. It has a strategic position in the search for solutions to environmental problems and faces philosophical, ethical, epistemological challenges in local and global challenging contexts [53, 57]. As in the context of other disciplines, and particularly ethnosciences [58, 59], there are three useful paradigms that can guide the ethnobotanical research.
Sustainability Science
At a first level, seeking sustainable management of natural resources elucidates the need to develop models that: (1) maintain and restore the natural resources and ecosystem processes, (2) strengthen the social organization of the sectors that interact with ecosystems and resources, and (3) generate more equitable economic processes [60–62]. In the scientific literature, there are numerous references to the great difficulties in operationalizing the concept of sustainability. Among other limiting factors, the specialization and reductionist methods that dominate contemporary scientific research can be mentioned [63, 64]. Due to the complexity of common epistemic frameworks articulated under different fields of knowledge, another of the great challenges is to include the participation of different stakeholders in addressing socio-ecological problems, as well as the attention to the various scales at which they occur [63–66].
Several authors have raised the need to develop a sustainability science [67] whose essential features are recognized to be: (a) that the problems associated with natural resource management must be viewed from a systemic point of view, both from a social and ecological perspective, as these form all socio-ecological systems, (b) the design of interventions in these systems requires interdisciplinary interaction and the participation of different social sectors, (c) such approaches must consider operating processes in trans-scalar systems, and (d) the complexity of the systems and the high level of uncertainty that exists requires the adoption of interim intervention schemes subject to ongoing assessments of experiences and effects (adaptive management).
In the context of sustainability science, ethnobotany has much to contribute. The information documented through the research approaches considered in this study are of great relevance in making decisions about harvesting resources and techniques as well as the socio-economic and ecological implications of such use. Ethnobotany also has a close relationship with community development processes among its many purposes; an important one is analyzing the different dimensions of production in terms of natural, economic, and socio-cultural implications and significance [68, 69].
Participatory Research and the Dialogue of the Different Forms of Knowledge
Ethnobotany encourages the process of community participation in the management and administration of natural resources. One of the major obstacles in solving environmental problems is the lack of participation [70, 71]. Through participatory processes , it is feasible to generate horizontal and reciprocal relationships within the community and external agents to strengthen the social fabric and decision-making related to the use and enjoyment of natural resources [72]. Today, there are many participatory approaches seeking sustainability with regard to the exploitation of natural resources [73, 74] and they are useful for visualizing the cross-interaction networks that must be woven together to successfully achieve the project objectives.
Conventionally, transfering of information and technology arising from research institutions has been unidirectional and flowed top-down [75]. This process has led to confrontations in at least two different knowledge structures putting peasant knowledge in opposition to technical–scientific Western perceptions [76]. This has often resulted in significant cultural transformation [77–79].
While ethnobotany may significantly contribute to sustainable management processes of resources and ecosystems, as well as reassessing and documenting local management practices, encouraging ownership of “technology” in a particular cultural context implies that it must be related to topics of interest to the community [72]. This approach represents reverse knowledge transfer from a community to other areas (e.g., Academic sectors), with respect for local ideas, arguments, and innovative capabilities as a means to strengthen the processes of organization and community development [80]. In this sense, the dialogue of knowledge paradigm [81, 82] is an approach that is useful for interchange between different social sectors such as no governmental organizations, rural, periurban and urban stakeholders, governmental institutions, and academic sectors. Ethnobotany can and should adopt such paradigm and promote research around wisdom, knowledge, and values in the relationship between plants and human beings with cultural, economic, ecological, political, and social differences.
Cultural transformation affects not only the technological aspects of the appropriation of nature, it also generates changes in social structure, habits, and consumption patterns of land use and resources, which can generate gradual differences between the needs of young and old, between migrants and residents, among original groups and mestizos, etc. [83]. Accordingly, ethnobotany can play an important role in building communication bridges between sectors of a community helping to maintain balanced information exchange and preserve cultural values in rural communities.
Intellectual Property Rights, Bioprospecting, and Biopiracy
Today, intellectual property rights relating to natural resources is a topic of much debate worldwide. It is sparked by conflicts between rural communities generating knowledge, skills, and proprietary of genetic resources on the one hand, and large companies that make use of such resources and knowledge for private profits on the other [84]. The topic is certainly of great importance in the context of respect for cultures, equity, and human rights.
The exploration of biodiversity in search of genetic and biochemical resources with commercial value (bioprospecting) based on traditional knowledge brings with it the issue of biopiracy. Pat Mooney defined the term in 1993 [85] and described it as “…the use of intellectual property to legitimize the exclusive right and control of knowledge and biological resources without recognition, reward or protection of the contributions of indigenous peoples.” Biologists and ecologists in general have been signaled from members of academic and non-academic sectors, as voluntary or involuntary partners in the process of bioprospecting, and worse as collaborators in biopiracy. Therefore, there is a social and political demand that ethnobiologists should participate actively in creating alternatives to protect and preserve the rights of the indigenous people on their traditional knowledge and their genetic resources.
According to Toledo [55], in Mexico, there are numerous examples of natural resource management within what he calls “the silent revolution.” This movement included nearly 15 years ago more than 2000 cases of ejidos and communities, associations, and cooperatives in over 12 states of Mexico. It is possible to state that this number has significantly increased during the last years because of the social resistance movements including demands in relation to natural resources, property rights of genetic resources, and biosafety. This movement engaged processes like: (1) agro-ecological and organic products, (2) sustainable forest management, (3) non-timber forest resource extraction, (4) defense of territory and natural resources, and (5) ecotourism projects. Anta and Pérez-Delgado [86, 87] and Toledo et al. [88] documented more than 800 community events in the sustainable management of natural resources in the states of Michoacán, Oaxaca, and Quintana Roo alone. It is precisely in the context of these civil society movements aimed at sustainable management of natural resources, in which ethnobotany’s relevance is most pertinent and currently most needed. Its active role in the generation of information to answer questions about the kosmos, corpus, and praxis related to the plant world is of great value to support the processes of technological innovation, social organizational and institutional linkages that can guide local strategies, and policies with the goal of achieving locally and globally sustainability and equity. As well as helping to identify those whose knowledge should be recognized and the knwoledge that should be recognized.
Conclusions
According to the information analyzed, ethnobotany in Mexico experienced a diversification of approaches, a decreasing trend in the 1990s with a recovering during the last decade (2010). The number of studies recorded increased and decreased in different areas, suggesting that Mexican ethnobotany is still dynamically evolving. The information suggests that Mexican ethnobotany emerged closely related to ecological, economic botany, and floristic studies. The predominant approach has been descriptive ethnobotany, focused on a limited number of research institutions, regions, and people. One of the challenges facing this field of research in Mexico is therefore to direct their growth seeking to strengthen the diversity of approaches and research groups, particularly more analytical-focused approaches as well as strengthening research groups especially in institutions that are outside of Mexico City.
Ethnobotany is an area of research that addresses questions regarding kosmos, corpus, and praxis in relation to plants. It combines anthropological, botanical, ecological, and evolutionary approaches, among others. However, it is infrequent that specialists of different disciplines converge, being more common for specialists to penetrate into domains beyond their specialty areas to address their ethnobotanical questions. This condition suggests that ethnobotany is still facing the challenge of developing interdisciplinary interaction mechanisms and further transdisciplinary research approach. The latter are particularly relevant in a research field in which knowledge of cultural groups is the main focus. The development of disciplinary, interdisciplinary, and transdisciplinary approaches is very important to address the issue of strategies for the sustainable use of natural resources and ecosystems.
