The widespread dissemination of internet technology gave rise to a new economic modality centered on digital platforms that influenced several segments, including agribusiness. This dissertation aims to identify opportunities for marketing agribusiness products on digital platforms. To achieve this purpose, it is intended, firstly, to carry out a literature review using the prism methodology, encompassing publications in the Web of Science (WoS), Scopus, Scielo, Science Direct and Periódicos Capes databases; analyze data from sellers participating in the examined marketplace and carry out an on-line survey with the companies that are part of this digital platform that is the subject of the study. The survey with sellers evaluated five conceptual questions arising from the articles evaluated. The results revealed that virtual marketplaces reduce intermediaries, expand the company's reach, diversify marketing channels and increase sales. The interviews also indicated that manufacturers must offer comprehensive solutions, beyond the product, making services and technological packages digitally available to increase the attractiveness of the transaction. The work detected that the five themes addressed by the authors in the 102 articles researched were ratified by the companies, showing that virtual marketplaces have become an accelerated trend that must be considered by companies that intend to remain competitive. Another observation observed is linked to trust, configuring itself as one of the main factors for analyzing sales on digital platforms, notably when it comes to transactions involving high-value equipment, since these operations still arouse the interest of physical contact more direct with the product. In conclusion, the study discovered new facts linked to the commercialization of machines in digital environments, a topic that has not yet been explored commercially or academically. Around 80% of sales on the analyzed platform came from agricultural machinery and equipment, being one of the few e-commerce platforms specialized in this sector in the world, which made it a reference in the area due to its sales volume and for adding to its environment the main manufacturers on the market. This information was communicated to the marketplace managers, who recognized the importance of concentrating even more efforts on this aspect, given the unique competitive advantage developed, hitherto not observed on other similar digital platforms in different countries.

The analysis of soybean and corn production in Brazil reveals significant challenges in the production chain of these grains. Studies and investigations point to a considerable deficit in grain storage in the country, despite the constant annual increase in production, which continues to break records. However, transportation logistics, essential for the productive chain, face serious problems, failing to keep pace with the growth in production and population. This is reflected in additional challenges for producers, who deal with damaged roads, lack of maintenance, and insufficient capacity at ports to handle the entire cargo, resulting in significant delays in ship replenishment. Faced with these challenges, producers find themselves compelled to overcome constant obstacles, from planting to grain sales. In this context, storage emerges as a viable solution for agricultural production in Brazil, providing better returns for producers. However, establishing a grain warehouse requires identifying suitable locations, significant investments, and, above all, the capacity to store the entire production for future sales with higher profitability. Given this scenario, it was recognized that mathematical modeling can provide essential support for decision-making on the best location for establishing soybean and corn warehouses, as well as help evaluate the necessary investments. This study aimed to enrich a mathematical model for the location and storage of soybeans and corn through interviews conducted with soybean and corn producers and engineers specialized in grain storage, combined with a literature review. Additionally, an analysis of mathematical models present in the literature related to the topic of this study was proposed to examine the data used. The interview audios were transcribed, and the data were processed and categorized using the MAXQDA® software, providing a better understanding of the interviewees' responses. A comprehensive table was then compiled, containing all the variables identified in the interviews, totaling 243 variables extracted from 274 responses. For the development of this table and to strengthen the mathematical model, variables identified in the interviews were selected, along with variables used and published by other authors, especially those related to the opening and location of corn and soybean warehouses. At the end of this study, after conducting analyses and comparisons, the proposed objective was achieved, providing a comprehensive table containing relevant data for the opening and location of soybean and corn warehouses.

The research seeks to analyze the impacts of adopting the corporate type of a holding company in agribusiness companies on the transaction costs of those companies, as well as the limits of these impacts for companies

Changes in the business models of the organizations have promote the advance of economies aligned with the promotion of socio-environmental and economic transformations, ensuring the most efficient use of resources and social interactions, as in the case of sharing economy. Sharing has been consolidated as na alternative for producers to improve their performance, notably those linked to agrarian reform rural settlements, which face difficulties in accessing resources and comercializing their products on the market. This work aimed to know how sharing economy practices can contribute to improving the production performance of milk producers in rural agrarian reform settlements. This work has a qualitative approach, of an applied nature and with an exploratory and descriptive objective. Regarding the technical procedure, a multiple case study was carried out. The results showed that the sharing of items such as machines, tools and equipment, in addition to the sharing of knowledge, skills, information and animals contribute to improve the performance of milk production. By promoting transformations and adaptations in production processes, the sharing economy guarantees milk with superior quality, produced more quickly, increasing the buyer’s dependability, in addition to causing less environmental impacts, better quality of life for producers, increased revenue and lower production costs. In conclusion, it was identified that the sharing economy contributes to improving the performance of milk production at the social, strategic and operational levels.

Producing food and feeding the world in the face of growing demand faces a paradox, since available resources are limited and increasingly scarce. On the other hand, the optimal combination of production factors contributes to cost reduction. Thus, the search for efficiency, more and more, has been shown to be a key factor in achieving competitiveness. However, just being efficient is not enough, the current challenge is to add the environmental factor to the production process and to the analysis of efficiency, what they call eco-efficiency. The objective of this work was to analyze the eco-efficiency of agriculture in the Midwest Region and its determining factors, in order to identify the best practices, offering information and tools for decision-making and implementation of public policies aimed at agriculture. This is a study with a quantitative approach, with an applied nature and exploratory objectives. Data Envelopment Analysis (DEA) was used as a method with resampling technique (bootstrap) and truncated regression to estimate unbiased eco-efficiency indicators and their determining factors. The results demonstrate that there is room for agriculture in the Midwest Region to become more eco-efficient, reducing inputs and greenhouse gas (GHG) emissions and increasing revenues and environmental preservation, equiproportionately, in the order of 32.2%. Access to credit and technical assistance were the exogenous variables that most influenced the region's economic-environmental efficiency. These results led to the conclusion that it is possible to save resources and pressure on the environment, with increased production, with production financing and technical guidance as tools of great impact in promoting eco-efficiency.

As a result of consumers' concern for sustainable and socially correct products, the Brazilian Corn Production Chain is going through a transition phase. In this sense, this work proposed to identify initiatives within the scope of the Academy and contextualize them with the Brazilian reality and thus identify actions that accelerate the transition. From the perspective of Prospective Studies, a Systematic Literature Review was carried out involving 66 articles, a questionnaire was applied to 72 rural producers and 23 interviews with chain specialists. The studies indicated the following practices: biotechnology, reduction of nitrogenous fertilizers, crop rotation, reduction of losses and waste, digital agriculture, reduction of CO² emissions and production of bioenergy, biogas, biofuel and bioplastic. The questionnaires encompassed 206,000 hectares spread across 15 Brazilian states and indicated that rural producers already rotate 13 crops, practice direct planting, second harvest, use biological products, cover planting and integration with livestock farming. Aiming at a contextualization in the international scenario, it was compared with the precepts of the UN Sustainable Development Goals (SDGs) and also with the European Ecological Pact. The main conclusions from the evaluation of the selected literature and the statements in the interviews and questionnaires led to the conclusion that Brazil is relatively well-positioned with regard to sustainable agricultural practices, the adoption of technology, the energy model and environmental legislation. The adoption of the Crop, Livestock and Forest Integration (ILPF), the implementation of the Forest Code (although still pending), the Low Carbon Agriculture Plan (ABC) and the Renewable Energy Matrix and the adoption of sustainable practices justify this conclusion. It is still necessary to advance in traceability, combating illegal deforestation, encouraging Ecological Industry and sustainable processing, controlling contamination of groundwater and encouraging sustainable consumption and reducing losses and waste.

Non-Conventional Food Plants (PANC) have a close relationship with farmers and traditional communities, presenting themselves as a theme of immense potential to be explored in the most diverse areas of research, since they are of great importance for the subsistence of individuals, especially in situations of economic vulnerability. In this sense, the PANC are inserted as a promising natural resource, with several health benefits. The present study aimed to prospect information about the presence of non-conventional food plants in organic fairs in the Federal District, with the purpose of contributing to the dissemination of knowledge about these species, with the increase of diversity in the diet and with the dynamism of the local economy. This is an exploratory, qualitative, and multi-case study. 20 fairs were visited, and 24 producers/marketers were interviewed in different administrative regions of the DF. Data collection was carried out through face-to-face semi-structured interviews. Information about the trader's profile, characteristics of the activity, as well as the perception of the interviewees about the activity were collected. About 80% of respondents knew the term PANC. For most, knowledge comes from childhood, mainly passed on by grandparents. Among the best known and consumed PANC are: ora-pro-nóbis, taioba, peixinho and beldroega. It was found that 88% of respondents produce PANC on their properties and claim that they represent a significant economic gain, generating extra income for the family. The offer is not greater due to lack of knowledge of both producers and consumers. The need to disclose the species and their nutritional and social importance to society was observed.

The existing technologies in Brazil for sustainable soy production have been gaining prominence in the national and global context, and are also the result of the current demands of society for rapid transformations in sustainability indicators. The objective of this work was to identify the operational practices of sustainable agricultural management that are being adopted by producers located in the municipality of Rio Verde – GO within the voluntary market of certified soybeans from the perspective of good agricultural practices. It was sought to highlight the different productive profiles of the groups evaluated, to characterize the degree of adoption of producers for the methods of soybean cultivation more sustainable and, finally, to describe the main approaches and technologies implemented in loco by producers. As for the methodological aspects, it is a research of an applied nature and as for the objectives, it is a descriptive research. The methodological instrument used to identify these factors was the case study, with the selection of 22 producers certified in responsible soybean in the standards of the Round Table on Responsible Soy – RTRS. The results show that certified soybean producers have average productivity levels between 73 bags/ha and a maximum of 81 bags/ha. In this respect, it can be noted that more than 55% of the certified producers declare that they have already advanced between 50% and 100% in relation to the replacement of old practices by organic ones. In another analysis, it was found that the model adopted by the producers is oriented to the diversification of crops with green cover plants (turnip-forage, crotalaria, brachiaria, beans, sorghum and millet) and, consequently, with little adherence to crop rotation given the local context. It was also identified that producers make use of herbicides, insecticides and fungicides and, to a lesser extent, for nematicides. On the other hand, it was verified the use of the no-tillage system (SDP), Integrated Pest Management (IPM), Integrated Weed Management (MIPD) and Biological Nitrogen Fixation (BNF) technique, being actions that contribute to the strengthening of Good Agricultural Practices (GAP). With regard to operational agricultural practices, it was noted that producers frequently perform soil analysis for correction of macro and micronutrients, as well as the use of inoculants through seed treatment and/or in the planting furrow with micron. In addition, it was verified the implementation of periodic evaluation practices for pest and disease control in order to reduce the use of chemical inputs. In addition, it was found that producers are adherent to bioinputs, in this aspect, with the use more focused on bio-based insecticides and fungicides, for example, bacteria of microorganisms, seaweed, bacillus  bacteria, fungi of the genus Trichoderma, Beauveria Bassiana and fungi of the genus  Metarhizium Anisopliae used as a microbial pest control agent. Therefore, it is concluded that the adoption and practices of operational soil management recommended by the producers in this research have a positive relationship with the current literature on sustainable production. In this aspect, it is recorded that the increase of pests and diseases in the field, increase of production costs and boost of the international market, tend to induce the agricultural transition of producers to certified soybean production. Thus, producers have much to gain in this process, being even protagonist of a more sustainable agricultural production in the country.

The discussion on the tripod of sustainability is latent and transversal to several areas of knowledge, mainly with regard to food and the concept of food heritage. The aim of this systematic review is to discuss whether the promotion and enhancement of food heritage are catalysts for sustainable territorial development. The review showed that different ways of valuing the food heritage are being developed and discussed on several continents, however, the discussion on territorial development is treated as a consequence of secondary importance 23 or is even not mentioned. The discussion was divided into three main axes: i. transition of agrofood systems and heritage valuation initiatives as a means for sustainable rural development; ii. Use of food heritage by tourism as a tool for cultural promotion and a possible driver of sustainable rural development; iii. The formalization of food heritage as a promoter of sustainable rural development.

The global medicinal plant market is constantly growing, reflecting consumer demand for natural products to promote a healthy lifestyle. In recent years, the trade in medicinal and aromatic plants has become promising and a source of economic growth for family farming. With this, the objective is to characterize the production and extraction of medicinal plants in the Sílvio Rodrigues Settlement – Alto Paraíso (GO), aiming at the promotion of health, conservation of socio-biodiversity and the socioeconomic development of the community. The project will be carried out in the microregion of Chapada dos Veadeiros, in the Silvio Rodrigues Settlement, located 34 km from Alto Paraíso (GO). This research is classified as applied nature with a qualitative and quantitative approach and descriptive objective. About technical procedures in data collection, non-participant observational research and semi-structured interviews will be carried out. Data will be analyzed using Content Analysis and Statistical programs. With this, it is expected to identify possible production chains related to medicinal plants in the region and to identify the main challenges and opportunities for the sustainable development of this market. In addition, valuing local knowledge and contributing to the academic environment in a way that encourages research and innovation on medicinal plants and herbal medicines.

Nutritional quality in school meals and family farming are important segments of public policies, with the focus of the first segment falling on the quality of meals offered and consumed, with a view to supplying nutritional needs and improving school performance, and the emphasis the second addresses the guarantee of income and quality of life for small farmers with predominantly family work. Internationally, family farming has provided, in particular, fresh vegetables for school contexts, contributing to the improvement of the quality of the students' diet. Quality is a subjective concept, socially constructed from experiences, perceptions and representations shared by actors in their reference groups. Different quality conventions coordinate economic activity in the agri-food sector and given its marked importance on the part of economic actors, it instigates greater research efforts on quality conventions that coordinate local purchases from family farming for school meals. This study aimed to analyze how the perceptions of different actors about the quality of food provided by local family farming to the National School Feeding Program (NSFP/PNAE) in a large urban center, the Federal District (FD), influence the coordination of this economic activity. For this purpose, the multipaper format was chosen, revealing, initially, the state of the art on the subject in question, in the international sphere, and, finally, the case study. A bibliometric analysis of 2,042 articles retrieved from the Web of Science was carried out, using the CiteSpace software version 5.7.R2, in addition to a systematic review of the literature published in the Web of Science and Scopus databases, using the Methodi Ordinatio protocol, with a total of 30 articles in the analyzed portfolio, and finally a case study in the Federal District, Brazil, with 35 school feeding actors. In the case study, the content analysis of the interviews was carried out with the support of the Iramuteq software, in the light of the theory of conventions. The results of the literature showed that the nutritional approach is still current in research but has given way to other aspects. As for the design of the surveys examined, longitudinal studies are particularly relevant, as is the relationship between local purchases by family farming and the quality of school meals, which is more concentrated in the southern region of Brazil. The literature also points out that local purchases from family farming contribute to the quality of school meals with nutritious, fresh foods and due to the proximity between production and consumption, while acquisitions in this category generate income for family farmers, favoring local development. In the Federal District, quality conventions promoted food democracy, reconciling various coordination perspectives, which both maintained and shaped the PNAE quality standards, welcoming and negotiating the perceptions of multiple actors in the qualification process. The producer and consumer links shared common worlds of coordination, but the principles evoked were not always the same. This dissertation advanced the discussion by identifying and analyzing the state of the art internationally and, later, addressing the perceptions of different nodes of this short chain, adopting the theory of conventions, which had not yet been applied for this purpose. Additionally, it provides subsidies to PNAE planners, in addition to pointing to an agenda for future research, which may be relevant to be read by farmers, public managers and family farming organizations, researchers and students.

In Brazil, family farming is extremely important, both in terms of volume and the destination of its production. It greatly contributes to food security, both by serving a significant part of the domestic market, and for social development, by providing people to remain in the countryside and in maintaining employment. However, this segment has been on the margins of the development observed in the field, experiencing difficulties that threaten its existence. In this context, it is worth highlighting the adoption of organic production as an important alternative for family farming, enabling greater gains due to the higher added value of certified products. Therefore, access to credit policies represents a fundamental condition for family farmers to be able to convert their production to the organic system and keep it competitive – which requires investment, knowledge, and specialized technical assistance. To encourage the adoption of the organic production system and offer competitiveness to family producers, in 2003, PRONAF Verde credit lines were created. Despite the creation of these lines, apparently so advantageous to producers, access by organic family producers is still little used. Thus, understanding the process of granting credit to organic family producers and the reasons that lead them not to access these lines of credit is extremely important, being able to subsidize eventual revisions of their rules, formulation of public policies and implementation of government actions. In view of the above, the present study aimed to analyze the process of obtaining rural credit from the perspective of organic rural producers, verifying the adequacy of credit lines, the indebtedness profile, the difficulties, and the facilitators, seeking to identify the reasons that would justify the non-adherence of producers to these lines. The methodology used in the construction of the research was the multipaper modal, where each chapter has its own objective, literature review, research method, results, discussions, and conclusions. It was noticed that associations and cooperatives can play an important role as promoters of security for the credit process, positively influencing the analysis of so-called interested parties, facilitating access to credit by family and organic farmers and that a large part of organic producers develop its production activities with its own resources. The most relevant reasons for not contracting credit are linked to the credit granting process – notably, the lack of knowledge of the lines and technical assistance for project preparation. It was also noted the need for greater approximation of producers with institutions that support organic agriculture to improve learning, diversify and improve production, as well as their relevance to assist in improving the process of obtaining credit on the part of the producers in the dissemination of lines and project development. It was concluded that there is a need for efficient and articulated action by the State and other entities participating in the process of granting credit for organic family farming, in the sense of disclosing the available credit lines, their procedures for obtaining and required documentation, in addition to the urgency in training and availability of specialized technical assistance for the preparation of projects and monitoring; and also, it was noticed the need to review the lines in question, making them more attractive for producers in terms of business, as well as less bureaucratic, considering the particularities of organic producers and the organic production system.

Public policies in Brazil play a fundamental role in the rural sector development. This dissertation relates to the Fundo Garantidor Solidário (FGS), established by Law 13.986 of 2020, known as the Nova Lei do Agro. Defended as an alternative to traditional guarantees of rural credit and as an inductor of new possibilities for private financing, the study aimed to investigate its elaboration process. It also sought to identify the actions of interest groups, the challenges for implementation and the prospect of adhering to this new form of guarantee by the target audience. For that, a literature review was carried out in order to verify existing studies on the subject, a documentary research, a manifestation in the Plataforma Integrada de Ouvidoria e Acesso à Informação do Governo Federal (Fala.BR) and data collection through semi-structured interviews. The results show that this public policy was perceived as unfeasible by the interviewees due to the requirements of composition of the fund, the complex operational model and the lack of information on the part of those who would be the beneficiaries, which led to its non-use and consequent amendment of the law two years later, in 2022.

Brazilian agricultural knowledge and sustainable technologies for the sector are topics of great interest for both the national and international markets, given the country's economic development. It is also added to the expectations of the scientific society about the investigations, in the development of science and technology (S&T), necessary to achieve satisfactory results for environmental conservation and social and economic development. In this way, the present work refers to the evolution of innovative knowledge of the Brazilian agricultural sector, which advances at an accelerated pace, making it essential to incorporate sustainable technologies in the production process, as well as the examination of technological trends that the sector presents. currently and in perspective. Through a conceptual evolutionary analysis of innovation and its reflexes, from the perspective of economic development, mapping of technologies developed by the largest national agricultural research company, Embrapa, and analysis of the results obtained from the prospective questionnaire of scenarios used to sector experts , the sustainable technological trends that will be priorities for development and implementation in the near future are envisaged

Food loss and waste is a problem that affects sustainable development, occurring throughout the food chain. Food waste happens in the final phase of the chain where the consumer is a protagonist in this process, and many variables lead to waste in homes. This research aimed to analyze which variables most induce consumers in the Federal District (DF) to waste food. This is an applied research, exploratory and descriptive, of quantitative approach with the use of a questionnaire as a research instrument, applied through an online platform. Statistical analyses were used, such as Chi-square test, Pearson coefficient, Mean Iten Score, for data analysis. Among the main results, consumers claim that they prefer healthy, fresh and food-free food. Most of the respondents are women. Consumers make shopping lists and have a habit of taking advantage of leftovers, but many still claim to leave leftover food in the fridge for too long, which leads to waste. In relation to disposal, organic waste is the most common route, which demonstrates contrary behaviour, which is followed by Europeans, for example, who have a waste management hierarchy. Consumers exhibited behaviors and were possible to divide them into two clusters. It can be concluded that the problem is complex, and further studies are still needed, because mitigating waste in homes is difficult and complicated. However, consumers in the Federal District tend to have the intention of not wasting food, which is an important behavior to avoid waste.

The complex forms of organizations that emerged in agribusiness support the focus of analysis on companies or organizations and on their social and commercial relationships, based on specific products. In this research, the inclusion of actors and their interactions is demonstrated in the use of the concept of networks, based on trust. The objective of the research was to identify the influence of trust in the relationships between the cooperative members of COOPERORG/DF, as well as between the cooperative members and the management of the cooperative, to contribute to the strengthening of the cooperative and boost its expansion in the market. The research is characterized as exploratory, applied, qualitative and a study case. When characterizing the demographic and socioeconomic profile of the cooperative members, important characteristics were observed such as the influence of the female gender in production and their prominence in the processing and improvement of organic products in the DF; the understanding of the relationships based on trust highlighted among the cooperative members and the reduced dimension towards the management of the cooperative. The cooperative members are unaware of the cooperative's rules and regulations, even though most of them have a degree. No leaders were observed in the cooperative. The board of directors cannot influence the actors. The gaps in cooperative management presented in this research demonstrate the importance of intra-organizational networks for the development of organizations. The main highlight is the informal relations between the cooperative members. However, these relationships do not stand out in organizational dynamics. Although the literature highlights that smaller, homogeneous groups with internal norms have greater trust and reciprocity, obtaining greater social capital in the organization, this research reported an inverse scenario, of devaluation of social capital. The main contributions of this study are related to the presentation of the evolution of research on the subject, the indication of trust for the analysis of the intraorganizational network and the success of collective actions, as well as the identification of factors that converge to the role of trust in the construction and development of social capital.

The Vendas Balcão Program (ProVB) aims at small producers' access to public corn stocks of the Federal Government at subsidized prices. This program has a significant operating cost, and the purpose of this study is to reduce this cost by optimizing the flow distribution from a producing region using intermediate warehouses. Few studies were found on the flow of grains within the national territory to serve the domestic market. In this sense, this work proposes a linear mathematical programming model to support the decision on the best flow to meet the ProVB. Data were extracted from government agencies, tabulated, applied to the mathematical model and the results analyzed. As a final result several scenarios were analised and presented.
