Item Panorama dos 10 anos de vigência do código florestal brasileiro(Universidade Federal de Goiás, 2023-12-18) Araújo, Lorrainy da Costa Vieira; Barreira, Sybelle; http://lattes.cnpq.br/8803862948788380; Barreira, Sybelle; Cruz, José Elenilson; Pires, Patricia PereiraThe Brazilian Forest Code, Law No. 12.651/2012, turned 10 years old in 2022, and during this period, the federal entities drew up rules to regulate the state's need to deal with the themes of the Forest Code's chapters. The general objective of this study is to analyze the developments of Law No. 12.651/2012 in the states and the Federal District, and the specific objectives are to catalog the regulations of the federated entities related to the period of 10 years after the Forest Code came into force; to identify the normative acts of the states and the Federal District on the subject of the chapters of the law; to analyze the developments in the context of the sub-themes of the Rural Environmental Registry, Conservation Units, Fires and Deforestation; and, finally, to develop a dynamic platform. The research was carried out by collecting secondary data, so the methodological procedures began with an electronic search on the government websites of each federal entity, starting with the Union and searching state by state in alphabetical order; The information collected was entered into an Excel spreadsheet to catalog the data and create a database, so that, after completing the survey of normative acts, the results were presented using a Power BI dashboard, which is a dynamic platform, as well as maps in graphical formats. The results show that measures need to be taken to ensure that Law 12.651/2012 is applied effectively throughout the country, in order to guarantee the protection of native vegetation and the sustainable use of forests and other forms of native vegetation in Brazil.Item Gestão empreendedora e Sistema Agroflorestal (SAF): o caso das guerreiras do assentamento Canudos, em Goiás(Universidade Federal de Goiás, 2023-08-31) Ribeiro, Mariana; Sibov, Sérgio Tadeu; http://lattes.cnpq.br/4627553641870284; Mozena, Wilson Leandro; http://lattes.cnpq.br/9052207260053937; Souza, Cleonice Borges de; http://lattes.cnpq.br/8449949211640425; Souza; Souza, Cleonice Borges de; Cruz, Fabiana Thomé da; Hora, Karla Emmanuela RibeiroThe adoption of Agroforestry Systems contributes to the socioeconomic and environmental development of family farming. In this context, rural women play an important and challenging role in ensuring food and nutritional security, agroecological practices and promoting territorial development. Although invisible, these women play an important role in domestic production and economy. The objective of this study was to evaluate the use of management strategies in the socioeconomic development of the AFS das Guerreiras de Canudos, of the Settlement Canudos, in Palmeiras de Goiás-GO. The research, of qualitative and quantitative nature, is analytical and descriptive, being conducted through action research. To obtain the data, bibliographical and documentary research was carried out, in addition to participatory rural diagnosis techniques, such as a questionnaire, semi-structured interview, analysis of the internal and external environments, and the elaboration of cartographic maps. The study showed that the adoption of management strategies has a positive impact on the socioeconomic development of women warriors, maximizing the benefits of AFS. It highlights the importance of valuing women's work, gender equity and the need for public policies that consider diversity in the context of women for rural development. It is suggested to deepen the discussion of the gender issue, its senses and disagreements, in the rural sphere, since it is women who suffer the most gender discrimination.Item Determinantes da adoção da tecnologia de controle biológico da mosca-branca com o fungo Cordyceps javanica(Universidade Federal de Goiás, 2023-07-31) Borges, Mariely Moreira; Quintela, Eliane Dias; http://lattes.cnpq.br/7426637066408803; Wander, Alcido Elenor; http://lattes.cnpq.br/8250997651281553; Teixeira, Sônia Milagres; http://lattes.cnpq.br/1596947832723945; Teixeira, Sônia Milagres; Wander, Alcido Elenor; Cruz, José Elenilson; Assunção, Paulo Eterno VenâncioThe excessive application of pesticides has had negative effects, not only on nature, water quality and food security, but also on human health. In addition, the growing resistance of insects to chemical insecticides has made it difficult to control pests such as the whitefly. Among the 17 Sustainable Development Goals (SDGs) chosen by the UN, the second aims to eliminate hunger, ensure food security, increase nutrition and promote sustainable agriculture. The goal is to double agricultural productivity and the income of small food producers by 2030, in addition to securing food production systems and implementing resilient agricultural practices. In view of this, it is essential to expand integrated pest management strategies, including biological control. Lallemand and EMBRAPA, together, formulated a biological product based on the fungus Cordyceps javanica, known as Lalguard Java. The objective of this work is to evaluate which factors are involved in the adoption of this biological product. Through a qualitative and quantitative research that used groups. Most seniors have low education, in addition to this there is a clear difficulty in accessing quality information, which can negatively influence the adoption of new technologies. Products that know the effectiveness of biological control are 81.81% more likely to adopt biological control with the fungus LALGUARD JAVA if it is efficient in controlling the whitefly and if it does not cause harm to humans and the environment. Producers who know the effectiveness of biological control have a 135.57% greater chance of adopting biological control with the fungus LALGUARD JAVA if it presents a cost and mortality level similar to those of chemical control.Item Mercados e comercialização de produtos lácteos pela agricultura familiar nas feiras livres de Goiânia-GO(Universidade Federal de Goiás, 2023-06-30) Segundo, Charla Basílio Schinaider; Cruz, Fabiana Thomé da; http://lattes.cnpq.br/1043014066439621; Cruz, Fabiana Thomé da; Menezes, Sônia de Souza Mendonça; Corcioli, GraciellaProducts sold at free fairs historically originate from what is currently considered family farming, forming circuits of social interaction that enable the producer to establish relationships with consumers and between them and food. In this sense, the markets accessed by family farming can then be seen as strategic spaces in which new services and products can emerge, as well as practices – both productive and product commercialization – that are different from those found in the conventional system, having the potential to become consolidate, culminating in new processes of rural development. For this reason, this study was justified by the importance of analyzing the characteristics of the commercialization channels of dairy products accessed by family farming, especially free fairs, by the significant and traditional production of milk in the state of Goiás by family farming and in addition to this, the lack of data showing the role of family farming in relation to dairy products sold in these spaces, not only in Goiânia, but also in the state. From these perspectives, the present study aims to analyze strategies and dynamics of commercialization channels accessed by family farmers for the commercialization of dairy products at free fairs in Goiânia-GO. Specifically, the study intended to systematically review the literature on commercialization channels accessed by family agriculture and analyze how the commercialization of dairy products by family agriculture at free fairs in Goiânia is configured. After applying a questionnaire to all stallholders who sell dairy products at the 105 fairs in the capital of Goiás, it was found that the marketing of these products occurs, in large part, by middlemen, who purchase products both from other middlemen and directly from producers, which are manufactured within the state of Goiás or purchased in Minas Gerais. Of the 185 interviewees, 43 are producers of dairy products and of these, only 32 consider themselves family farmers, producing fresh milk, assorted cheeses, butter, and milk sweets, which are offered weekly at the free fairs in the capital. The results also reveal that, among producers, family farming has little autonomy to carry out direct sales, without the presence of middlemen. The products deserve attention and recognition, since most of what is sold at the street markets in Goiânia is produced in Goiás, so that family farming in the state can be valued and strengthened. It is hoped that the analyzes presented here will contribute to highlight the potential for valuing and participating in family farming in the food composition of Goianienses in relation to dairy products.Item Avaliação executiva da assistência técnica e extensão rural do programa "Promoção da Agricultura Familiar Sustentável" no município de Campo Alegre de Goiás(Universidade Federal de Goiás, 2023-02-28) Martins, Jean Louis Alves; Oliveira, Guilherme Resende; http://lattes.cnpq.br/4435590881986017; Oliveira, Guilherme Resende; Cunha, Cleyzer Adrian da; Carneiro, Maurízia de FátimaThis work is an executive evaluation of the Technical Assistance and Rural Extension (ATER) provided in the program “Promotion of Sustainable Family Agriculture” in the municipality of Campo Alegre de Goiás, object of a contract between the Ministério de Desenvolvimento Agrário (MDA) and the Agência Goiana de Assistência Técnica, Extensão Rural e Pesquisa Agropecuária (Emater), implemented between 2015 and 2017. The executive evaluation allowed establishing an overview of this Public Policy in the selected public through the analysis of data from structured interviews and semi-structured, documentary analysis of the beneficiaries' credit projects in the file of the Local Unit of Emater in Campo Alegre de Goiás, observations and informal conversations with the families of producers carried out in the visits to the Family Production Units, the evaluation proposal in this research/evaluation project was carried out in the municipality with a total of 83 families remaining from the original group of 100 families, This is the death, retirement from the activity and sale of the property due to illness of 17 producers, divided into 5 groups spread over 5 communities: Paulista, Paulista/Sesmaria, Conceição/Boa Vista, Calaça/Soledade and Rancharia , proving the effectiveness of technical assistance and rural extension actions in improving pasture management, management and genetic improvement of the dairy herd, increased milk and forage productivity, protection of springs, recovery of riparian forests, adoption of agroecological practices, reduction of toxic inputs, reduction of costs, leading to an increase in net income, which impacted the way of life of these families in terms of comfort and acquisition of consumer goods. The amount of the budget appropriation was sufficient to fund the actions towards the intended objectives and the Public Policy was carried out with reasonable costs (economy). As it takes place in a timely manner during policy implementation, the executive assessment is a faster and more targeted approach to adjusting public policy. According to Cohen and Franco (2004), a public policy evaluation is justified because it plays a central role in the rationalization process and is a basic element in the planning of a public policy with results evaluated by effectiveness.Item Benefícios da responsabilidade social empresarial: estudo de caso em duas agroindústrias goianas(Universidade Federal de Goiás, 2023-02-28) Pinto, Rosicler Aparecida; Cruz, José Elenilson; http://lattes.cnpq.br/3130838156334394; Cruz, José Elenilson; Wander, Alcido Elenor; Dias, Cleidson NogueiraCorporate Social Responsibility (CSR) refers to the set of economic, legal and ethical expectations that society has of companies at a given moment, which indicates that the responsibilities of companies go beyond those signed with their shareholders to capture society's demands of general form. In Brazil, CSR has been disseminated by a number of institutions specialized in the subject, such as the Ethos Institute for Business and Social Responsibility, which mobilizes, raises awareness and helps companies in Brazil to manage their businesses in a socially responsible manner. Despite the importance of these studies, there is a lack of research on the economic and non-economic benefits that CSR programs generate for companies that institute them especially for agroindustries in the state of Goiás, given that in the last 10 years little research has been carried out on CSR themes. . Thus, based on this gap and the relevance of describing how CSR has been guiding ethical conduct in business actions, enabling a comfortable and suitable environment for work, transparency and adding value to the production process, this study proposes to answer the question “What benefits, economic and non-economic, has Corporate Social Responsibility generated for two agribusinesses in Goiás?”. The general objective was to understand the economic and non-economic benefits generated by Corporate Social Responsibility for two agroindustries in Goiás. The justification for the elaboration of this dissertation is related beyond the researcher's training and performance, also considering that the agroindustries are in scenarios in which market values and economic variables are dominant. So, the social function of a company is not simply to worry about offering good services or products, but to expand the objective of acting and intervening in social, economic and non-economic practices. However, studies show that CSR is a strategic and competitive tool within agroindustries. In view of this, the relevance of this research is noted, which fills a bibliographical gap in the field studied from the defined clipping. This is a descriptive research, with a qualitative approach, with a bibliographic procedure, with a case study, in two agroindustries in Goiás, with document analysis and application of a semi-structured interview, using Bardin's content analysis and the Iramuteq tool. From the analyzes carried out, both of the documents and of the interviews and of the programs and projects, it is possible to say that the companies surveyed are mostly in the advanced stage, in line with the CSR stages included in the Ethos CSR Indicators (2007), based on ethical management with strategies to improve the quality of life of stakeholders and the company's economic growth, generating profitability. As a result, the research showed that the two agroindustries in Goiás had economic and non-economic benefits from CSR: brand recognition, cost reduction, increased production, market growth, energy cogeneration, financial advantages, increased gross revenue, preservation of water sources, reduction of gas emissions, preservation of the APP, employee satisfaction, social recognition and mitigation of social problems.Item Desempenho das exportações goianas do complexo soja para os principais parceiros comerciais: uma aplicação do modelo gravitacional(Universidade Federal de Goiás, 2023-02-27) Silva, Frederico Teodoro da; Cunha, Cleyzer Adrian da; http://lattes.cnpq.br/8809108474226649; Cunha, Cleyzer Adrian da; Silva, Adriana Ferreira; Wander, Alcido ElenorThe aim of this study was to analyze the performance of soy complex exports from the state of Goiás to the main importing countries - China, Netherlands, Thailand, France, South Korea, Spain, Germany and Iran - through the Gravity Model. The chosen period was from 2003 to 2019 and the destinations were selected because they had complete statistical information and because they represented approximately 88% of the Soy Complex exported by the state of Goiás. The Gravity Model was estimated in the formats Pooled, Fixed Effect and Random Effect, being the routines carried out in the R-4.1.2 software, taking into account the GDP of Goiás, the GDP of the importing country, the distance between the capitals, the price of soybeans and a binary variable that captures if China has a greater force in exports. According to the results of the three models, the export elasticity of the Soy Complex in relation to the GDP of Goiás is approximately 1.1% in the Pooled model, 0.64% in the Random Effect model. On the other hand, the export elasticity of the Soy Complex in relation to the GDP of the importing country is 1.81% in both the Fixed Effect model and the Random Effect model. The distance between the capitals was also a significant factor in the exports of the soy complex from Goiás. Furthermore, the results showed that China had a significantly greater influence on the soy complex exports from Goiás compared to the other importing countries. Therefore, the study concluded that it is vital to emphasize the strong dependence of Soy Complex exports from Goiás on China and the need to expand the diversification of these export destinations, in order to make them more diverse and less vulnerable to economic and political events restricted to a single country.Item Consumo do lácteo queijo cabacinha de Santa Rita do Araguaia em Goiânia: uma análise da disposição a pagar(Universidade Federal de Goiás, 2023-02-24) Nogueira, Jordana Cristhina Ribeiro Gomes; Cruz, Fabiana Thomé da; http://lattes.cnpq.br/1043014066439621; Ferreira, Marcelo Dias Paes; http://lattes.cnpq.br/3436824386339415; Ferreira , Marcelo Dias Paes; Wander, Alcido Elenor; Silva Neto, Waldemiro Alcântara daBrazilian farming has shown a certain degree of performance in recent years, boosting production and exports. Within this scenario, large-scale agriculture stands out. Mostly, family farming has been developed in ecological systems through communities based on solidarity economy and cooperatives. An example is the production of artisanal cheeses, such as the cabacinha cheese from Santa Rita do Araguaia (GO). Cabacinha cheese from Santa Rita do Araguaia is a typical cheese from municipalities located on the border between the states of Goiás and Mato Grosso. The highlight of this product prompts the following problem question: "What are the constraints on the consumer's choice of artisanal dairy cabacinha cheese from Santa Rita do Araguaia and what is the willingness of consumers in Goiânia to pay for this product?" Considering this research question, the general objective of this dissertation is to analyze the willingness to pay, as well as its constraints, of the Goianiense consumer for the dairy cabacinha cheese from Santa Rita do Araguaia. The specific objectives are: to identify the profile of consumers in Goiânia of cabacinha cheese from Santa Rita do Araguaia; understand the consumer's purchase decision process; analyze the valuation potential of this product. The hypothesis is that consumers are willing to pay a higher price for cabacinha cheese from Santa Rita do Araguaia (GO), in relation to other cheeses, as it is an artisanal and traditional product, which highlights its historical and cultural value. This is quantitative research in the field research style, which adopts a literature review and exploratory, followed by the Random Utility and Estimation Model, with the application of closed questionnaires. As the main considerations of the research, it is possible to say that the willingness of consumers from Goianiense to pay for artisanal cabacinha cheese from Santa Rita do Araguaia (GO) is estimated to be high since a DaP of R$60.86/500g remained. In addition, among some constraints on the part of the consumer, it is worth mentioning that the choice to purchase this dairy product is based on age, place of purchase of the product and place of origin of the consumer. Although this result is heterogeneous, when considering the place of sale and the geographic origin of the consumer.Item Efeitos da gestão no desempenho econômico e ambiental da pecuária de corte no Cerrado goiano(Universidade Federal de Goiás, 2022-04-28) Naves, Ana Carolina Alves Rodrigues; Jesus, Andrelisa Santos de; http://lattes.cnpq.br/9279471449282134; Souza, Cleonice Borges de; http://lattes.cnpq.br/8449949211640425; Souza, Cleonice Borges de; Cruz, Fabiana Thomé da; Santos, Patricia Guarnieri dos; Araújo, Fernando Moreira deThe lack of application of management methods in the productive activities of rural properties results in a limitation for producers to continue to produce with economic and environmental sustainability. Well managed and managed agricultural activities have the role of maximizing the profitability of the activity and minimizing environmental impacts. The management of the rural property is necessary to subsidize the permanence of the activity in the agricultural market, which represents the guarantee of producing food, using the strategy of sustainable competitive advantage. The objective of this work is to analyze the effects of management on the economic and environmental performance of rural properties in the micro-region of Pires do Rio-Goiás. This research is of an applied nature, with a qualitative-quantitative and descriptive approach, with artificial participant observation. It is also documentary, since it used secondary data from the SENAR+ Project, from a group of 23 rural properties that joined the Technical Assistance project dedicated to beef cattle, as well as the IBGE database (Censo Agropecuário, 2017). Data on the quality of pastures and the Rural Environmental Registry (CAR) were compared to verify the preservation of the legal reserve and Permanent Preservation Area (APP) before and during the execution of the project, via remote sensing evaluation with Planet images, which guarantees 5m accuracy using Google Earth Engine and QGIS. It was identified the existence of gaps regarding the management of productive activities, the resistance of the producers to the new production techniques and the remote sensing allowed to evidence changes in the quality of the pastures and the state of preservation of the legal reserves and APP, which are not preserved in its entirety, which generates inconsistencies about the environmental sustainability of these activities. It is concluded that pastures considered to be in a medium degradation stage do not generate profitability for producers.Item As relações entre os agentes da cadeia produtiva do feijão-comum (Phaseolus vulgaris L.) e a inserção comercial da tecnologia da resistência ao mosaico dourado(Universidade Federal de Goiás, 2022-02-25) Oliveira, Gilmara Martins de; Wander, Alcido Elenor; http://lattes.cnpq.br/8250997651281553; Wander, Alcido Elenor; Cunha, Cleyzer Adrian da; Assunção, Paulo Eterno VenâncioThe common bean is one of the primary plant-based protein sources for the Brazilian population and plays a vital role in ensuring food security. The crop is susceptible to some diseases, including the golden mosaic that has caused significant crop losses. EMBRAPA developed a cultivar with adequate resistance to golden mosaic through transgenic technology. Thus, the objective of this research was to study the relationships between the agents of the production chain of the common bean and the commercial insertion of the technology of Resistance to Golden Mosaic (RMD). To this end, a mapping of the production chain of kidney beans in Brazil was carried out, seeking to understand the relationships between agents and the transactions present in the chain. An analysis was made on the position of bean producers regarding the adoption of the technology of resistance to the golden mosaic and the possible changes resulting from the insertion of RMD technology, considering some aspects of a successful insertion. The consultation made with the common bean producers showed that most of them favor the use of transgenic seeds resistant to the disease, and that they would be willing to pay more for the acquisition of the input. It is characterized as quali-quantitative research, with exploratory and descriptive character, using bibliographic, documental and field survey research. Data was collected using an electronic questionnaire and telephone calls to producers; the sample was composed of 15 participants. It is expected to contribute to a better understanding of the production chain of common beans and points out aspects that need to be considered for the commercial insertion of RMD technology to be successful and bring improvements to the production chain of common bean.Item Análise da competitividade de laticínios em Goiás(Universidade Federal de Goiás, 2022-02-28) Bernardes, Nívea dos Reis; Cruz, José Elenilson; http://lattes.cnpq.br/3130838156334394; Cruz, José Elenilson; Nacife, Jean Marc; Cavalcante, David Frederik da Silva; Cunha, Cleyzer Adrian daBased on the economic and social importance of the milk production chain for Brazil and the state of Goiás, specifically, and given the lack of research that points out which factors (internal to companies, market structural and systemic) most affect the competitiveness of Brazilian dairy agroindustries, this study aimed to analyze the competitiveness of dairy products in the state of Goiás. The specific objectives were to characterize the milk production chain in Brazil and in the state of Goiás, identify the degree of concentration of the dairy sector in Brazil and test a theoretical model of relationships between internal, market structural, systemic factors and competitiveness. of dairy products in the state of Goiás, under the theoretical perspective of systemic competitiveness proposed by Coutinho and Ferraz. Secondary data sources were used to characterize the sector, and to identify the degree of market concentration at the Brazilian level. The test of the theoretical model of hypothetical relationships was performed based on primary data collected from a non-probabilistic convenience sample of 27 respondents. Data were analyzed using structural equation modeling (SEM). The results show the numbers of the dairy sector in Brazil, the prominent position of the state of Goiás on the national scene and the growth of milk uptake by dairy in recent years. Overall, the results indicated a moderate degree of concentration of the dairy industries in Brazil, based on the calculations of the CR4 and CR8 Concentration Ratio indices and the Herfindahl-Hirschman index (IHH). Finally, the analysis of the empirical data through the MEE indicated that of the three natures of factors tested as independent variables, only the structural market factors positively affected the competitiveness (dependent variable) of the researched dairy agro-industries. The results have positive implications for the companies investigated regarding the reformulation of strategies and the improvement of the decision-making process. To the literature, the study contributes by expanding knowledge about the competitiveness of the dairy agroindustry in Brazil, and by making available to future studies on the subject an empirically validated research scale.Item Análise da concentração e expansão da produção e do beneficiamento do milho-pipoca (Zea mays L. var. everta (Sturtev.) L. H. Bailey) no Brasil(Universidade Federal de Goiás, 2022-02-23) Bertolucci, Murilo Fernandes; Cunha, Cleyzer Adrian da; http://lattes.cnpq.br/8809108474226649; Cunha, Cleyzer Adrian da; Wander, Alcido Elenor; Godoi, Cintia NevesO objetivo do presente estudo foi averiguar a concentração e expansão da produção e beneficiamento do milho-pipoca (Zea mays L. var. everta (Sturtev.) L. H. Bailey) no Brasil. O modelo utilizado foi o ECD (Modelo Estrutura, Conduta, Desempenho) e os índices analisados foram o HHI (Herfindahl-Hirschman Index) e o CR4 (Razão de concentração das 4 maiores empresas). Para mensurar o tamanho do mercado e seus agentes nos mais diversos elos foram realizadas entrevistas com os agentes dos elos de interesse da pesquisa. Os dados secundários utilizados para determinar a competitividade da cadeia foram volume e o preço das sementes de milho-pipoca importadas e dos grãos do cereal exportados e importados no período, além de dados do Registro Nacional de Cultivares (RNC) para demonstrar o incremento no número de novos cultivares disponíveis. Os resultados revelaram que há concentração de mercado tanto no elo fornecedor de sementes quanto no elo indústria processadora e que devido a maior especificidade de ativos, esta é maior no elo dos fornecedores de sementes. Concluiu-se também que a cadeia produtiva é competitiva tanto em nível nacional quanto internacional.Item Plantio de eucalipto e o serviço ecossistêmico de captura e armazenamento de carbono(Universidade Federal de Goiás, 2022-02-22) Lacerda, Matheus Souza; Ferreira, Marcelo Dias Paes; http://lattes.cnpq.br/3436824386339415; Barreira, Sybelle; http://lattes.cnpq.br/8803862948788380; Barreira, Sybelle; Calil, Francine Neves; Ferreira, Jorge Luís SousaCommercial forest plantations are currently an important economic activity of Brazilian agribusiness, through technological, economic and social development, the sector has experienced considerable advances in the last few years. However, there is little information about the relationship of commercial forest plantations and ecosystem services approach. In this way, this analysis aimed to contribute to the environmental, social and economic debate through the principles of ecological economics, in this way, the analysis focused on the carbon sequestration service performed by a commercial forest plantation of eucalyptus, for this it was necessary to follow three fronts for research construction; I) quantification of the carbon stock and carbon equivalent of the plantation through a biophysical assessment carried out in the field, where information on volume, density, biomass, carbon allocation and carbon equivalent (CO2) of the area were collected. II) carried out the economic valuation of the carbon stock provided by the commercial forest plantation of eucalyptus, according to the social carbon cost (CSC), in which it is an important metric capable of translating the service of atmospheric carbon retention into monetary values, because in its construction there is a greater range of social, economic and climatic factors. III) Assessed the contribution of eucalyptus forest plantations on the emissions of the city of Goiânia, the analysis was made through the carbon balance data of the report of the System of Estimates of Emissions and Removals of Greenhouse Gases (SEEG) revealing the impact of planting mitigation and its importance to face the climate crisis underway across the planet. The quantification of carbon stock and carbon equivalent was 108.44 t/ha of carbon and 397.96 t/ha of carbon equivalent, the monetary economic valuation was 2,602.44 US$ per hectare, reaching 130,122.38 US$ for the entire planting according to carbon stock and US$ 9,550.98 per hectare reaching US$ 477,549.13 for the entire planting, according to the valuation of carbon equivalent, the analysis of the contribution of planting, verified a potential for mitigating emissions of the city of Goiânia of 0.90% of the municipality's total emissions in 2018, results that demonstrate the ability of eucalyptus forest plantations as a sink for atmospheric carbon and to offer society well-being, through the allocation service, however as an economic activity, forestry projects need to be deepened, developed and interacted with the ecosystem services they perform.Item Desafios e possibilidades da regularização fundiária no processo de herança intergeracional da agricultura familiar no município de Silvânia-GO(Universidade Federal de Goiás, 2022-02-28) Ximenes, Sara de Lima Saeghe Alcanfor; Corcioli, Graciella; http://lattes.cnpq.br/5838446995807079; Corcioli, Graciella; Chehab, Isabelle Maria Campos Vasconcelos; Cruz, Fabiana Thomé daIn order to access some public policies, the family farmer needs to have his rural property in good standing, and its non-compliance may lead to competitive limitations, as an example, the promotion of policies such as the National Program for the Strengthening of Family Farming (PRONAF) and the National Program for Land Credit (PNCF). To address the problem, the study aims to investigate the challenges, causes, consequences and possibilities of addressing the lack of legal equity regularity in the process of intergenerational inheritance in family farming in the municipality of Silvânia-GO, delimiting two local communities as objects of study and the obligations related to the processes of patrimonial succession, considering the legal framework, the entry into force of the Civil Code/2002. This exploratory and documental research describes the scenario, including the period of SarsCov-2, the COVID-19 pandemic, the laws in force that are applied to family farmers, as benefits and main legal confrontations. The research analyzed the reasons for not regularizing, and, if this has already been done, the farmers' access or not to public policies. As a result, it was observed that the heirs who regularized their lands did so by means of judicial inventory and usucaption, an unusual institute for generational inheritance issues. The heirs who remain on the land are mostly middle-aged and elderly, and do not know about the public policies described above or, if they do, they have not accessed them.Item Barreiras ao sucesso da implementação da indicação geográfica no arranjo produtivo local do açafrão de Mara Rosa - GO(Universidade Federal de Goiás, 2022-02-24) Costa, Rhynaldo Ribeiro da; Cruz, José Elenilson; http://lattes.cnpq.br/3130838156334394; Cruz, José Elenilson; Wander, Alcido Elenor; Corcioli, Graciella; Dias, Cleidson NogueiraWith a cultivation model based on the traditions of the region, the saffron of Mara Rosa, which has adapted well to the climate and lands of the region, made possible a unique production of the spice, so the producers came together and within the actions of the cooperative members for expansion, it was requested and granted the creation of the Geographical Indication of Saffron of Mara Rosa. However, the research in the APL pointed out that the certification has not been implemented so far, so the present text, which is divided into three chapters, aims to identify in general the barriers to the successful implementation of the GI in the Mara Rosa-Go APL. The methodology was descriptive, composed of semi-structured interviews with APL actors. The analysis of the data from the face-to-face meetings was based on the relevant interview questions (Content Analysis) which dealt with the activities that are carried out in the routine of rural producers and the reflections and evaluation on how these were processed. Configuring itself, therefore, as a qualitative approach. The results pointed to issues related to land tenure, lack of labor, in addition to the producers' difficulties in complying with the technical standards imposed by the cooperative, from planting to delivery of saffron for processing.Item Modelo de predição da ocorrência de ferrugem asiática na cultura da soja a partir de variáveis climáticas e clusterização(Universidade Federal de Goiás, 2022-02-24) Côrtes, Filipe da Silva; Abdalla, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdalla, Klaus de Oliveira; Wander, Alcido Elenor; Heinemann, Alexandre BryanAsian rust is a disease with a significant impact on soybean in Brazil. Despite the great economic relevance of soybeans for Brazilian agribusiness, there are few studies on the conditions that cause the disease. This work aimed to create a predictive model considering the influence of climatic variables (temperature, precipitation, humidity and solar radiation), based on a dataset of rust occurrence, using the decision tree induction technique and logistic regression . The model was created with data on the occurrence of the disease in the cities of Cristalina, Jataí and Rio Verde - GO in the harvests from 2004/05 to 2016/17. For each occurrence record (detection), a corresponding “non-occurrence” was generated, this being the thirtieth day prior to the day of detection, assuming that on this date there would be no inoculum present in the field. The training set for the modeling has 10 variables totaling 393 records. The predictive model was proposed from the comparison of the best performance between the decision tree and logistic regression algorithms. After the accuracy results obtained (decision tree 77.88%, against 56.53% of the logistic regression algorithm), we used the clustering algorithm to group the data in the data preparation phase, again comparing the result between decision tree and logistic regression. With the support of clustering, we obtained the average accuracy in the range between 99 and 100% for decision tree and 66.75 and 100% for logistic regression.Item Identificação de plantios florestais de interesse comercial em Goiás: classificação supervisionada de imagens multiespectrais(Universidade Federal de Goiás, 2022-02-24) Oliveira, Sabrina Gomes de; Barreira, Sybelle; http://lattes.cnpq.br/8803862948788380; Barreira, Sybelle; Calil, Francine Neves; Acerbi Júnior, Fausto WeimarGoiás is still at the beginning of the development process of its forestry sector, and a breakdown of the total area of each of the commercial species is necessary due to the state's potential to insert itself as a relevant forest figure in the country. Thus, the objective of this work was to identify and quantify the area of forests planted with Eucalyptus spp., Khaya spp. and Hevea spp. through supervised classification of Sentinel-2A images dated between 02 and 22 of august, 2021. The classification supervision resulted in the sampling of 820 polygons, these differentiated into nine classes of land use and cover. The global accuracy of the Random Forest model was 96.11%, in addition to a Kappa index of 95.26%. For area calculation, a predominance of Eucalyptus spp. (90,583 ha), but also a very significant portion of Hevea spp. (23,213 ha) individuals. Khaya spp. are still the minority in the state. The total area of planted forest in Goiás with the three specific genera is 115.094,65 hectares. There is, however, a deficit in forestry resources, a delay in terms of wood and energy needs, a fact that can be confirmed in contact with industries.Item Terra, Estado e reforma agrária: ilegitimidade da cadeia dominial do imóvel destinado ao assentamento Mosquito (Goiás-GO)(Universidade Federal de Goiás, 2022-02-14) Silva, Emanuel Jeremias Ramalho da; Corcioli, Graciella; http://lattes.cnpq.br/5838446995807079; Corciol, Graciella; Ribeiro, Dinalva Donizete; Oliveira, Adriano Rodrigues deThe aim of this study is to analyse the process of constitution of the Mosquito Settlement Project, located in the municipality of Goiás-GO, examining the origin of the property "São Sebastião" or "Mosquito" as a legal nature; the role of the State, especially through INCRA and IDAGO, in dealing with the peasants' demands during the period of occupation of the farm and the process of expropriation of the property; and the fulfilment of the expectations of the land reform beneficiaries during the development of the Mosquito Settlement Project. An in-depth survey of the property was carried out, covering the period from 1857 to 1985. A careful examination of the history of the property revealed a series of irregularities, with particular emphasis on the lack of a foundation and connection between the various registers and the alleged owners. It was found that the property was not separated from the public domain, and that its legal nature as a public asset was still preserved; therefore, it was a wasteland that should have been recognised as being under the domain of the State of Goiás, by means of a discriminatory action, to be proposed by IDAGO. The refusal of the organ responsible for this recognition led to expropriation for agrarian reform purposes in 1986, with the consequent convalidation of errors and unsanctionable defects in favour of the owners - who benefited from the expropriation indemnity amounts. Furthermore, the property was repeatedly assessed as being unviable for a settlement project, given its low quality for agricultural activities, which was confirmed by the work carried out by INCRA and SEBRAE in the Recuperation Plan for the Mosquito Settlement, in 2006, which found low productivity; losses in the supply of food for the settlers; evasion of approximately 50% of the original beneficiaries; and a lack of prospects for succession.Item Viabilidade econômica de sistemas de Integração Lavoura-Pecuária-Floresta (ILPF): o estudo de caso da Fazenda Boa Vereda – Cachoeira Dourada – GO(Universidade Federal de Goiás, 2022-02-25) Teixeira, Lara de Carvalho; Calil, Francine Neves; http://lattes.cnpq.br/2520537051838618; Calil, Francine Neves; Wander, Alcido Elenor; Pacheco, Abílio RodriguesThe increased demand for food has made Brazil one of the main global players in agribusiness, focusing on the production and export of several agricultural products. Due to the environmental, economic, and social appeal, integrated production systems, such as Crop-Livestock-Forestry Integration, have been considered the future of agriculture. Regarding the economic approach, the system is based on the diversification of income-generating activities, with different moments of revenue entry and reduction of the risk of financial losses. Thus, the objective of this work is to evaluate the economic viability of the second rotation of an Integrated Crop-Livestock-Forestry (ICLF) system and to stimulate the adoption of integrated production systems in other properties based on the success cases of Boa Vereda farm in the municipality of Cachoeira Dourada, in the state of Goiás, central-western region of Brazil. The integrated system is composed of the following crops: soy, corn, forage (Piatã), beef cattle, and eucalyptus. The technical coefficients were obtained at the Boa Vereda farm and the prices used for economic evaluation were obtained from the Institute for the Strengthening of Agriculture in Goiás and in the local market, for the 2020/2021 harvest. The economic indicators used to evaluate the economic viability were the Net Present Value and the Uniform Annual Equivalent Value. It was not possible to use the Internal Rate of Return, due to reports of errors in the calculations, as it did not present negative values in the first years of implementation of the system.The results showed that the integrated system of second rotation is viable for the producer, both for cutting at 6 or 14 years, presenting a return greater than the opportunity cost of land, which shows the attractiveness of the ILPF system. Therefore, this system presents an economically viable alternative, which has other benefits that allow the diversification of revenue sources, with reduced risk, in addition to making the productive area more sustainable.Item Efeito da concentração da soja e algodão na produtividade de culturas essencialmente dependentes da polinização animal no centro-oeste brasileiro(Universidade Federal de Goiás, 2021-07-05) Frias, Vinícius Diniz; Abdala, Klaus de Oliveira; http://lattes.cnpq.br/8041644148923970; Abdala, Klaus de Oliveira; Franceschinelli, Edivani Villaron; Ferreira, Marcelo Dias PaesAccording to FAO’s data (2004) approximately 73% of agricultural species cultivated worldwide are pollinated by bees. However, a steady decline in the population of these pollinators has been observed in several countries and the indiscriminate use of pesticides has been pointed out as a major factor in this process. This master teses aimed to analyze the effect of the locational presence of soybean and cotton crops which use pesticides that are harmful to pollinators on the productivity of crops sensitive to pollination in central-western Brazil (a region that has significant productivity for agribusiness in Brazil). For this, a quantitative approach was adopted using statistical tools especially regression analysis through the development of an empirical model in order to test the hypothesis that municipalities that have not planted soybeans and/or cotton have higher productivity of pollinated crops than in municipalities that have planted soybeans and/or cotton, as well as to verify if the presence of forest remnants (habitat of native bees) favor the ecosystem service of pollination contributing to the productivity of crops essentially dependent on this service. The results suggest that the increase in the cultivation of Soy and Cotton in the Brazilian Midwest does not interfere in the productivity per hectare of the crops analyzed.
