Abstract: Food sovereignty is a complex problem of sustainability, since it requires the active and effective participation of diverse communities of knowledge for the identification and implementation of relevant and sustainable solutions. It is a complex problem that cannot and should not be treated sectorial or unilaterally (e.g. from the academy or from the public sector). Otherwise the proposed solutions would be destined to an imminent failure. Transdisciplinarity is proposed as an approach to successfully deal with complex sustainability problems, since it allows transcending disciplines and sectors. There are few experiences about the co-creation of food sovereignty from a transdisciplinary approach at international and national level. This essay presents a case study in the Municipality of Tiraque about the co-creation of food sovereignty at two scales: municipal and communal level. Although the results are preliminary, there are already lessons from the field. The formation of collaborative and transdisciplinary research teams requires patience and time. Once the teams are formed, interesting dynamics emerge. Preliminary results show the importance of working with young people through agroecological schools and linking them with knowledge transfer networks such as the agroecological committee.

Resumen: La soberanía alimentaria se constituye en un problema complejo de sostenibilidad, ya que requiere de la participación activa y efectiva de diversas comunidades de conocimiento para la identificación e implementación de soluciones pertinentes y sostenibles. La soberanía alimentaria es un problema complejo que no puede y no debe ser tratado de manera sectorial o unilateral (ej. desde la academia o desde el sector público). De lo contrario las soluciones planteadas estarían destinadas al fracaso inminente. La transdisciplina se plantea como un enfoque para lidiar exitosamente con problemas complejos de sostenibilidad, ya que permite trascender disciplinas y sectores. Existen pocas experiencias sobre la co-creación de soberanía alimentaria desde un enfoque transdisciplinario a nivel internacional y nacional. Este ensayo presenta un estudio de caso en el Municipio de Tiraque sobre la co-creación de la soberanía alimentaria a dos escalas: nivel municipal y comunal. Si bien los resultados son preliminares, ya se cuenta con lecciones aprendidas del trabajo de campo. La conformación de equipos colaborativos y transdisciplinarios de investigación requieren de paciencia y tiempo. Una vez conformados los equipos, emergen dinámicas interesantes. Resultados preliminares muestran la importancia de trabajar con la juventud a través de escuelas agroecológicas y vincularlas con redes de transferencia de conocimientos como el comité agroecologico.

People have been working together to address shared problems since the beginning of civilization, and, over time, they have devised many ingenious ways of organizing to accomplish collective endeavors (Emerson & Nabatchi, 2015a, p. 3).

Two of the main concerns of humankind are to cover the food necessities of a growing population and to reduce poverty (Atkins & Bowler, 2016). Throughout the post-industrial period two groups of discourses dominated the agricultural policy and practice with the goal of dealing with these concerns: 1. Production innovation/technology; and 2. Economic Growth (Thompson & Scoones, 2009).

The production innovation/technology narrative started during the industrial revolution with the aim of dramatically increasing productivity and output by improving agricultural efficiency (Overton, 1996; Thompson & Scoones, 2009). At the beginning, mechanization and fertilization of agriculture was highly promoted, later, in the middle of the 20^th century, came the Green Revolution (GR) with the development of high yielding crop varieties (Atkins & Bowler, 2016; Thompson & Scoones, 2009). Since the 1990's the GR shifted to a Gene Revolution, based on "molecular science and recombinant DNA" to create Genetically Modified Organisms (GMO) with a primary focus on the private sector (Atkins & Bowler, 2016; Thompson & Scoones, 2009).

The GR has increased food production importantly in developing countries. In the early phase of the GR (1961-1980) a 21% growth in production was reported; and in the later phase (1981-2000) a 40% growth in production was reported (Evenson & Gollin, 2003; Thompson & Scoones, 2009). Despite this significant increase, food availability and accessibility is still limited for the poor, while several significant socio-environmental problems have arisen as consequences of the technological packages developed and used by this narrative (i.e. soil fertility loss, agro-biodiversity loss, water pollution, cultural erosion, etc.) (Pielke & Linner, 2019). For their part, GMOs' safety is controversial regarding human health and the environment (Atkins & Bowler, 2016; Ludwig, 2018). Also, high dependency of farmers of a few multinationals has been reported, dominating food production globally.

The economic growth narrative has some similarities with the production innovation narrative; however it focuses on the power of agriculture to take a country out of poverty (World Bank, 2005). This narrative aims at moving farmers from subsistence agricultural systems to commercial ones (OECD, 2206; Thompson & Scoones, 2009; World Bank, 2005). In general, it is based in a set of "stages" that need to be accomplished in order to achieve economic growth. It pushes for specialization, commercialization and globalization of agricultural production and marketing; which eventually also pushes for scale economies. To do so, it requires market incentives, institutional instruments and technological innovation. This narrative is promoted by numerous multi-lateral development agencies such as the World Bank and the International Monetary Fund (Thompson & Scoones, 2009). Although it aims at alleviating poverty, it has showed to impact negatively on farmers and their economy, specially, on small scale farmers. For example, they are impacted by heavy taxation policies and low prices for urban citizens (Krueger, 1996). Moreover they have become more vulnerable to price flows because of high levels of specialization (Timmer, 2009).

Although both narratives have shown to be able to increase food production, the main two problems of concern remain; poverty and poor's inaccessibility to enough and quality food. In 2016, approximately 804 million people were suffering of chronic hunger in the World, this number increased to 821 million in the year 2017 (1 out of 9 people in the World) (World Health Organization, 2018, p. xiii). According to Thompson and Scoones (2009), both narratives have "failed to provide sustainable outcomes" because "conventional agricultural science [...] is based on a static equilibrium-centered view that provides little insight into the dynamic character of agri-food systems" (Thompson & Scoones, 2009, p. 1).

2    Problem statement — co-creation of food sovereignty

In the last decades different agricultural alternatives have arisen, aiming at developing more sustainable and equitable food systems such as agroecology, permaculture and eco-functional intensification among others. Such alternatives follow eco-friendly and integral approaches for agro-ecosystems management, food production and commercialization. Agroecology is an alternative that stands out and is catching the attention of practitioners, researchers, politicians and activists because it is a set of practices, a science and a social movement that aims at reaching food sovereignty (Wezel et al., 2009). It focuses on the generation, protection and conservation of critical environmental services; and more importantly, it recognizes the dynamic nature of food systems which are deeply rooted in farmers' knowledge and skills, moreover, it recognizes the important role of all types of knowledge (Thompson & Scoones, 2009). Hence agroecology is the main promoter of the co-creation of knowledge, which "at farm-level, this translates into the re-skilling of farmers, who not only combine modern science and local knowledge, but (re)generate new, situated knowledge" (Coolsaet, 2016, p. 165).

Agroecology is characterized by a "transdisciplinary, participatory and action-oriented approach" by engaging different groups of stakeholders throughout a problem-solving process. Agroecology and PAR have common principles, hence they go hand in hand in the development of sustainable food systems (Altieri, 2000).

Numerous studies have showed that participatory alternatives do not necessarily fully integrate different stakeholders throughout the whole research and/or development project process (Minkler, 2004; Tress, Tress, & Fry, 2005). Figure 1 shows the degrees of integration and stakeholders' involvement in integrative and non-integrative approaches developed by Tress et al. (2005). Participatory alternatives show a low integration of academic and non-academic participants in environmental sustainability related processes. In general, especially in Latin America, PAR has been implemented by practitioners and activist without the participation of the academic sector (Agramont, Craps, Balderrama, & Huysmans, 2019). Likewise, multidisciplinary approaches which work only with academic participants (Tress et al., 2005).

Higher integration is present in interdisciplinary and transdisciplinary approaches. The later includes academic and non-academic participants (i.e. farmers, NGOs, consumers, government workers, etc.). In this sense, transdisciplinarity is seen as a "key condition for societal transformation towards sustainability" (Brink et al., 2018, p. 765).

Thompson and Scoones (2009) explain that governance¹ issues are absent in the narratives of agricultural development. Food governance dynamics should be an important focus for food systems transformation since they can influence their properties (Thompson & Scoones, 2009). According to Vorley (2002) governance is described by three main institutions: government, private sector and civil society (Vorley, 2002). He argues that a poor distribution of power and interests among these institutions "undermines the health and resilience of rural society, the farm economy and farmland ecology, even when executed in the name of 'sustainable development'" (Vorley, 2002, p. 16). In this sense, the dynamics of power relations among stakeholders may determine who's knowledge is "valid" or "valuable", hence, appreciating one type of knowledge and undermining another. Rosendhal et al. (2015) argue that such power relations tend to be overpassed by transdisciplinary research. Nevertheless, group empowerment may be achieved by exercising collaborative governance (Emerson, Nabatchi, & Balogh, 2011). Likewise, new spaces for agency may be created for stakeholders.

Emerson et al. (2011) explain that collaborative governance² can be supported by different theories such as co-production or co-creation, collaborative planning and participatory governance among others. Co-production and co-creation have become central for system transformation, since it aims at overcoming "traditional collaboration and participation structures" in order to foster sustainable systems (Emerson et al, 2011, p. 149). Moreover, it recognizes transdisciplinarity as an approach that leads to the "effectiveness of science and democracy" (Emerson et al, 2011, p. 149). Through collaborative governance, complex sustainable problems that involve different stakeholders from different organizations across scales can be approached with significant impacts that can lead to systems transformation (Emerson & Nabatchi, 2015a). Hence the fusion of collaborative governance and transdisciplinary approach may lead to true co-creation of food sovereignty.

Transforming food systems is the major interest of many developing countries; however, they do not necessarily aim at transforming them into sustainable systems, but they tend to follow a new wave of the GR, implementing similar political and technological packages. According to Marin et al (2016) some countries are still subject to processes of path dependency and lock-in, "consequently, attempts to introduce more sustainable practices in one part of an agri-food system are frequently incompatible with, or are undermined by, other incumbent components of the system as a whole" (Marin, Ely, & van Zwanenberg, 2016, p. 3). This means that sustainable transformations to agri-food systems are likely to require strategic, multi-actor, multi-process interventions at different scales.

Based on the above mentioned, transdisciplinary processes have the potential to overcome the path dependency and lock-in of agricultural development narratives through the co-design, co-production and co-dissemination of sustainable food systems which foster food sovereignty. Because of this outstanding potential, recently there has been growing interest in the study of transdisciplinarity; however, there still are several knowledge and implementation gaps.

For example, there is a study about the process of stakeholder involvement and co-production in the development of municipal adaptation strategies in two municipalities of Germany and Sweden with advanced governance structures, which shows an implementation gap regarding the operationalization of transdisciplinarity (Wamsler, 2017). However, there is a lack of similar studies in developing countries with less advanced governance structures aiming at transforming food systems for food sovereignty.

Currently the Catholic University of Bolivia in a Joint Research Programme with Ghent University is developing a doctoral research with the goal to contribute to fill these scientific and practical gaps by studying the co-creation of food sovereignty using a transdisciplinarity approach in a case study in Tiraque, Bolivia. The study has a special focus on power relations and empowerment. To do so, the research combines transdisciplinarity and collaborative governance frameworks. The present essay presents the progress made so far in the field.

3    Conceptual and theoretical approach

3.1 Transdisciplinarity for sustainable transformation

Integrative approaches emerge around the 1960's as counterpart to "autonomous and elitist approaches of science and higher education" (Tress et al, 2005, p. 481). A historic landmark for the development of integrative approaches is the 1970's Organization for Economic Co-operation and Development (OECD) Conference in Paris, where participants layout the incapacity of science to relate with society. As a result, relevant inputs emerged for the development of "disciplinary interactions" concepts (Tress et al., 2005, p. 482). Since then the integrative approach reached landscape ecology fields. Later on, due to the growing interest in sustainability a mayor integrative approach is required that includes ecological, social and economic dimensions (Tress et al., 2005).

According to Tress et al (2005), in general there are four types of disciplinary interactions: 1. Disciplinary; 2. Multidisciplinary, 3. Interdisciplinary; and 4. Transdisciplinary. Although there is a growing interest in these concepts, they are still confused between each other and used interchangeably, limiting their applicability and the end results (Tress et al., 2005). For example, in a survey to 232 researchers from projects in 28 countries around the World, only in 47% of the projects members had reached a common understanding of these concepts (Tress et al., 2005).

Table 1 describes each type of disciplinary interaction. They mainly differ in the "intensity of cooperation and integration of disciplines³" and "involvement of non-academic fields", the latter being a differentiating factor (Brink et al, 2018; Tress et al., 2005).

Transdisciplinarity transcends academia and integrates different types of knowledge and actors. Mauser et al.(2013) explain that in an integrated research people focus on solving problems in specific contexts rather than in disciplines. From their point of view, soon transdisciplinarity will lead the research World, with the active participation of different stakeholders such as civil society, enterprises, government and others, transforming non-academic actors into active producers of knowledge (Mauser et al., 2013). This shift will allow the co-creation of "socially robust" and situated knowledge, validated by its' outcome or impact on the system and by its' legitimacy (Mauser et al., 2013; Rosendahl et al., 2015, p. 18).

3.2 Transdisciplinary Conceptual Model

Throughout the years, different approaches and conceptual models to transdisciplinary research have been designed. This study uses Land et al. (2012). Conceptual Model of Transdisciplinarity which is based on Jahn (2008) Ideal-typical Conceptual Model. According to this model, transdisciplinarity is an "interface practice". On the one hand it is triggered by complex sustainable problems. On the other hand, it "relies on mutual and joint learning" between a wide range of stakeholders (academic and non-academic actors) (Lang et al., 2012). As a result, there are two pathways to deal with complex sustainable problems: one committed to the exploration of new options for solving societal problems; another committed to the development of interdisciplinary approaches, methods, and general insights related to the problem field.

There are three phases in the ideal-typical conceptual model:

A. Collaboratively framing the problem and building a collaborative research team;

B. Co-producing solution-oriented and transferable knowledge through collaborative research;

C. (Re-) integrating and applying the produced knowledge in both scientific and societal practice.

The final goal of phase A is to integrate both pathways mentioned before: "problem solution" and "scientific innovation" in order to foster phase B: collaborative research, which is the "integrative pathway" which ends up in situated knowledge that can be (re-) integrated in practice in phase C. See figure 2 for a detail explanation of the model.

3.3 Collaborative governance

According to Emerson et al. (2011) collaborative governance can foster empowerment of different stakeholders. Collaborative governance is linked to transdisciplinarity, co-production of knowledge and system transformation. This study understands collaborative governance as:

[...] the processes and structures of public policy decision making and management that engage people constructively across the boundaries of public agencies, levels of government, and/or the public, private and civic spheres in order to carry out a public purpose that could not otherwise be accomplished (Emerson et al., 2011, p. 2).

On the one hand, government officials are relying on collaborative arrangements to achieve public goals. On the other hand, activists and civic reformers want to "increase responsiveness and equity through collaborative governance" (Emerson & Nabatchi, 2015a).

There are different perspectives on collaborative governance: as institutional arrangements (new institutionalism), as structural relations (interactions and connections, network theory), as an advocacy coalition (competing coalitions), as a development process (negotiation process); and as a functional performance sequence (instrumental performance). Although these arrangements are useful to explore and explain collaborative governance, according to Emerson & Nabatchi they 'lack generality, therefore they usually cannot be applied "across different settings, sectors, geographic and temporal scales, policy arenas, and process mechanisms"(Emerson & Nabatchi, 2015a, p. 24). In 2011 Emerson et al. tackled these issues by designing Integrative Collaborative Governance Framework.

This framework can be applied to explain and assess governance across sectors (Emerson & Nabatchi, 2015a; Emerson et al, 2011). It is based on a wide range of concepts and knowledge from different disciplines that can be applied "across sectors, settings, processes, issues, and time" (Emerson et al., 2011, p. 2). Later based on feedback from academic and practitioners, they made some modifications to the framework. Figure 3 is the latest version of the framework. In comparison to other frameworks, it covers a small number of nested dimensions, which have different components that interact with each other producing actions. Those actions lead to outcomes, which should lead to adaption, however, in this case they should lead to system transformation.

Collaborative Governance Regime⁷ (CGR) is a central feature in this framework which is immersed in a specific system context, composed by political, ecological, legal and other "layered and interrelated conditions" that may affect the CGR or may be affected by it (Emerson & Nabatchi, 2015a, p. 39). From the system context essential drivers for collaboration emerge: leadership, consequential incentives, interdependence, and uncertainty. These drivers trigger the CGR. The CGR is shaped by collaborative dynamics among participants: principled engagement, shared motivation, and capacity for joint action). These cyclical collaborative dynamics steer the development of "collective purpose, a set of goals, and a shared theory of change⁸ to accomplish those goals", which lead to collaborative actions (Emerson & Nabatchi, 2015a, p. 27). Collaborative actions may result in outcomes that may generate impacts internally or externally (Emerson et al., 2011, p. 6). Emerson et al. (2011) developed their framework considering components present in other frameworks, however, they argue that their framework "configures them in a way that posits causal relationships among the dimensions and their components and elements", can be used to asses "intermediate outputs (actions) and end outcomes (impacts and adaptation) and become the basis for case evaluation and performance evaluation for program management" (Emerson et al., 2011, p. 22). However, indicators to carry out such evaluations haven't been designed yet.

This framework has been operationalized in 2015 by Emerson and Nabatchi, who constructed a multidimensional framework to evaluate the process and productivity of collaborative governance regimes (Table 4) (Emerson & Nabatchi, 2015b). The evaluation framework includes indicators to measure the antecedents and the construction of collaborative governance regimes (Emerson & Nabatchi, 2015b).

The Collaborative Governance Framework and the Transdisciplinary Conceptual Model have many similarities and can be integrated into one framework that allows exploring collaborative governance as a transdisciplinary process. Although, Collaborative Governance's final goal is adaptation through collaboration of different stakeholders across sectors, however, it doesn't assure integration. By integrating transdisciplinarity in the Collaborative Governance Regime, co-creation of knowledge for food sovereignty may be fostered. Table 2 presents the Collaborative Governance Regime to the right and the transdisciplinary components to the left.

3.5 Food sovereignty

At the World Food Summit of 1996, the peasant social movement Via Campina presented the concept of food sovereignty. It is defined as "peoples', Countries' or State Unions' RIGHT to define their agricultural and food policy, without any dumping vis-a-vis third countries" (Via Campesina 2003). According to Via Campesina, food sovereignty is about rights. For example, it is about the right to sustainable access land, seeds and water. It is also about the right to decide as farmers what to produce and of consumers of what to consume among other rights (Via Campesina, 2013). Later, other definitions of food sovereignty were developed, including this definition.

In parallel, there is a definition of food security

Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life (World Food Summit, 1996).

This definition is widely accepted and has been operationalized through the measurement of four dimensions: food availability, food access, utilization and stability (FAO, 2006). Although food sovereignty is the focus of this study, the notion of food security is used in order to define the level of insecurity in Tiraque.

4    Context

The present research proposal is framed in the Inter-University Cooperation Program VLIR UOS IUC - Catholic University of Bolivia (UCB). The Program's main objective is "to increase the resilience of vulnerable rural and urban communities so that they can respond to complex local problems related to economic, social and environmental aspects in Bolivia" (UCB 2018 p. 1). In its' first phase (2017-2021) the Program aims at creating Transdisciplinary Learning Communities (TLCs) at UCB's four regional universities (Cochabamba, La Paz, Santa Cruz and Tarija). In order to achieve its' goal, the Program is composed by six projects distributed in two strategies (VLIR-UOS, n.d.):

1. Improving and expanding currently developed UCB research in the areas of (a) social development and safety (Projects 1, 4 and 5), (b) environment and natural resources (Project 2), and (c) food sovereignty (Project 3) at the four regional UCB universities; and

2.  Integrating and transforming the aforementioned UCB's research into a transdisciplinary and collaborative learning community approach (Project 6).

Each project has its own set of goals however they are integrated through the TLCs in order to achieve the main goal.

This research is part of to the Inter-Project 3 (P3) entitled: Project to promote food sovereignty and nutritional innovation, which has the objective to "identify innovative strategies to promote food production, productivity and resilience, therefore contributing to reduce vulnerability in the communities located in the four eco-regions of Bolivia" (UCB, 2018, p. 3). This project is made up of three research areas: 1) conflicts over natural resources and technology transfer for food production; 2) agricultural production and productivity; and 3) agro-business and nutrition models. Although the present proposal will cover several aspects of the three research areas, it is specifically positioned in the research area 2.

4.2 Municipality of Tiraque

The Program has made significant progress in identifying vulnerable communities in La Paz, Oruro, Cochabamba, Santa Cruz and Tarija. In Cochabamba, communities have been identified based on vulnerability mapping in the municipality of Tiraque and through consensus with the TLC. Likewise, in Tiraque there has been progress in identifying its main problems and possible areas of strategic intervention. Among the main problems identified by the communities and social organizations of these municipalities, is the low production and agricultural productivity linked to ecological, socio-economic and cultural factors⁹.

Among the main ecological problems identified are the lack of strategic natural resources such as water and land, soil degradation, high incidence of pests and adverse climatological factors (i.e. frost). Among the most relevant socioeconomic problems are conventional agriculture, based on high use of external inputs, monoculture and the production of only a few varieties. Conventional agriculture has brought with it a series of negative impacts such as the substantial loss of agro-biodiversity and dependence on external inputs such as pesticides. Other problems identified are the importation of agricultural products with more competitive prices, lack of markets, scarce work alternatives, insufficient income, and lack of productive undertakings and failure of innovations. In the cultural dimension, the following factors linked to the loss local / ancestral knowledge and to nutrition have been identified: bad eating habits linked to the westernization of food and general devaluation of local and traditional food.

These factors increase the vulnerability of the communities, risking the food security of the population, in a country where a 21.3% prevalence of undernourishment is reported, ranking among the five most affected countries in Latin America and the Caribbean (FAO, 2014). Therefore, it is of vital importance to promote food sovereignty and rural innovation through the improvement of agricultural production and productivity. Experience has shown that this cannot be achieved by following neo-positivist approaches to rural research and extension, where technological innovation is imposed on communities. Hence, the P3 is following a transdisciplinary, action research approach, focused on agro-ecological innovation.

According to population projections for the year 2017, Tiraque has a population of 21 973 inhabitants (INE, 2017). It has a total of 121 Territorial Base Organizations (OTB's) scattered along four ecological zones. According to the Census results of the year 2012, 81.5% of the population of Tiraque has water coverage, 80.9% of electric power and 48.4% of basic sanitation (INE, 2017).

Tiraque is mainly an agricultural municipality. Nearly 9 976 hectares belong to annual crops and fodder, 13 hectares belong to fruit trees and 3 867 hectares are uncultivated (Candia Consultores, 2003). Potato is the major crop, followed by beans, peas, corn, wheat, barley, oats, goose, papalisa and others (INE, 2017). Cattle, sheep, pigs and horses are the main breeding animals in the municipality. Smaller animals such as birds and guinea poultry are breed mainly for family consumption (INE, 2017).

5    Methodology

On the one hand, a methodology was designed in order to answer each of the research questions of the study and to reach its' main goal of understanding to what extend food sovereignty can be co-produced by using transdisciplinarity in a collaborative governance regime. On the other hand, a methodology was designed in way that it can be easily replicated by similar studies.

5.1 Mix methods approach

The study follows a mix methods approach, in the sense that it combines a series of qualitative and quantitative methods, techniques, tools and activities. A mixed approach was chosen since it provides a deeper understanding of the research questions and corroboration through triangulation (Schoonenboom & Johnson, 2017). Moreover, a mixed methods approach will allow a better understanding of "diversity and the role of power differentials" (Mertens, 2007, p. 224).

The study will follow a transformative design because it is embedded in a transformative theoretical framework, therefore the "priority, timing and mixing of qualitative and quantitative methods can change" throughout the study (Schoonenboom & Johnson, 2017, p. 118). According to Creswell (2013) in such design "qualitative findings provide an enhanced understanding of the quantitative results in order to explore inequalities" (Creswell, 2013, p. 52).

Under a transformative design, the study will follow a cyclical model of research "that includes the establishment of partnerships between researchers and community members, including the recognition of power differences and building trust through the use of culturally competent practices" (Mertens, 2007, p. 224).

The following methods, tools and activities of oral, written and visual investigation are being implemented:

Transects. Communal transects are carried out with key informants at the initial phases of the research, since they allow obtaining preliminary information from the community: relevant agro-ecological characteristics, human activities, housing, etc. (Leeuwis, Leeuwis, & Ban, 2004). As a result, a cross-sectional view of the community is obtained. In general, transects are used as an initial step for other activities such as community maps and timelines (PAR, 2018).

Participatory community mapping. This visual technique allows obtaining information "on land use, agro-biodiversity and landscape features" (PAR, 2018, p. 68). In this way, the territory can be contextualized and the interactions of people with their environment can be visualized. Community mapping can trigger interesting discussions in the group; it can help people to focus on a theme, etc. (Chambers, 1992; Leeuwis et al, 2004).

Semi-structured and in-depth interviews. The semi-structured and in-depth interview allows access to the vision and perceptions of groups or individuals (Leeuwis et al., 2004). Leeuwis et al. (2004) explains that this type of interviews not only allow to explore what people do, how, where and when they do them, but also allow knowing why they do it. Initially, it is expected to conduct semi-structured and in-depth interviews with key informants (Tapia, 2002).

Focus groups. It is a type of group in-depth interview, in which a topic of interest is discussed with key informants. PAR (2018) explains that the focus groups are "particularly useful to find out about diversity distribution, important characteristics, management practices, constraints and opportunities, and any other topic" (PAR, 2018, p. 13). It is expected to conduct several focus groups per community in different phases of the investigation.

Surveys. The survey is a quantitative method par excellence that uses a structured questionnaire (PAR, 2018). Surveys will be carried out to obtain diverse socio-economic and agricultural information, with main emphasis on agro-biodiversity and nutrition.

Participatory observation. It is one of the main tools for the co creation of knowledge, since it allows the researcher to integrate naturally and actively in day to day routine of the participants of the research process (Delgado, 2010; Tapia, 2002).

Farmer to farmer learning. It is a learning approach based on exchange of experiences and participatory learning where farmers learn from other farmers through direct observation, questions and responses from one group to another(Fliert, 1993).

Data analysis will be developed as follows:

Network analysis. When working with case studies, researchers are dealing with "interconnected interactions among social actors, across time and space": networks (Leeuwis et al, 2004, p. 375). Under the notion of networks, researchers deal with social actors rather than individuals, since individuals "are in fact part of, or even constituted by, a wider web of relationships"(Leeuwis et al., 2004, p. 375).

Power analysis. Tell us who holds the power related to the matter, and what might influence them to change (Green, 2016, p. 38).

The study is following the three phases defined for the study's framework in Table 1

6    Preliminary results

The present study takes place at two scale levels: Municipality level and Community level. At the municipal level, the study is fostering the co-creation of Public Policy for Food Sovereignty. To do so it is relaying on the previous and recent development of a Public Policy on Water Sources Conservation in the same Municipality. The Project actively participated in the whole process of the development and approval of the Policy. The stakeholders involved are diverse: General Peasant Union, Bartolina Women Peasant Union, Health sector, Education stakeholders, Agroecological Committee, researchers and Environmentalist NGO's.

Furthermore, the study started a new collaborative governance regimen with a local school that wants to become and agroecological school. The project was approached by the Director and Teachers who want to improve the diet of their students by producing their own vegetables and fruits. To do so, a series of "farmer to farmer" activities and workshops were developed. Agroecological innovation will come as result of the research team (as defined in transdisciplinarity) and not from traditional scholars.

In parallel, the Project was reached by leaders of the Agroecological Committee of Tiraque. They want to create a network of agroecological schools and guarantee to provide their technical support in the process. The Committee is currently working in two collaborative researches with the project: 1. Peasant soil evaluation kit for land management decisions, and 2. Synthesis of the pheromone of the potato moth.

[...]rural youth around the world possess energy, creativity and a desire to positively change their world. What they need is support and opportunities. (FAO, 2018, p. 9)

So far, the process of transdisciplinary co-creation of food sovereignty has brought different lessons from the field. One of the main lessons is that the process requires time and patience, since the research group slowly conforms itself since it cannot be steered by the academic researchers. However, once the group is conformed interesting dynamics emerge. For instance, at the beginning of the research the agroecological innovation nor the target group was defined. It is an ongoing and surprising process: young participation in agroecological innovation.

Because of the lack of economic and resources youth is forced to migrate to urban centers, while traditional agricultural diversity and knowledge is eroding. Hence, working with the youth is highly important in rural communities of Bolivia. In general, young people are excluded from the decision-making process, hence their needs and opinions are marginalized. A study developed in communities near Lake Titicaca, stablished that "outmigration of young people is contributing to an erosion of traditional knowledge on practices for seed selection and cleaning, crop rotation, and traditional food recipes" (Meldrum et al., 2018, p. 724).

It has been shown that agroecology as a social movement can a be a space to "project another reality for the youth in rural spaces"(Ariza & Gazzano, 2018). In Uruguay, through agroecology claim access to land and active "participation and incidence in producer networks and local markets"(Ariza & Gazzano, 2018). Moreover, agroecology allows the revalorization and progression of agricultural traditional knowledge (Snipstal, 2015). Moreover, agroecological school gardens can be a spaces for community building and fostering social bonds and values (Gruberg, 2019) .

Beyond to their social benefits, school agroecological gardens improve the nutrition of students. For example, in a research about the effects of school garden experiences on middle school-aged students' in the United States of America, "results indicate that school gardening may affect children's vegetable consumption, including improved recognition of, attitudes toward, preferences for, and willingness to taste vegetables" (Ratcliffe, Merrigan, Rogers, & Goldberg, 2011, p. 36).

Although the Agroecological Committee is not conformed by young people, their link to them is highly important since they want to transfer their knowledge through the implementation of school agroecological gardens. At the same time, the Committee is part of a collaborative research on soil quality evaluation for land management decisions.
