The objective is to assess the influence of structural and institutional variables, such as education, agricultural research and development, CO₂ emissions, forest area, and employment in the agricultural sector, on productivity levels. A panel data econometric model with Newey-West estimators is applied to annual data from the group of countries. The results of the general model indicate that CO₂ emissions and agricultural employment are statistically significant, whereas education, R&D, and forest area do not show a consistent relationship with productivity. In the model estimated for nondeveloped G20 countries, R&D becomes significant, suggesting greater sensitivity to technological investment, while forest area exhibits a negative effect. Agricultural employment remains significant in both models, indicating an association between higher rural labor participation and lower productivity levels. The findings highlight structural differences between developed and nondeveloped countries and reinforce the need to incorporate institutional, financial, and logistical factors in future analyses.

As materials and methods, it employed a systematic literature review, an econometric analysis of official data from the Brazilian Institute of Environment and Renewable Natural Resources (Ibama), the National Institute for Space Research (INPE), and the Brazilian Institute of Geography and Statistics (IBGE), as well as a legal-institutional study focused on the assessment of federative competencies and the performance of Environmental Military Police forces. The results indicated that cattle ranching and soybean production remain the main drivers of deforestation, that the period from 2019 to 2022 was marked by significant institutional weakening with direct impacts on the increase of deforestation rates, and that state enforcement capacity can effectively complement federal action. The discussion highlighted the relevance of cooperative federalism and the need for innovative instruments to overcome operational weaknesses. As a final consideration, the creation of the National Environmental Force is proposed, composed of state personnel integrated under federal coordination, with multiannual financing and logistical support from the Armed Forces, as a strategy capable of restoring environmental police power, reducing impunity, and strengthening Brazil’s role in the protection of the Legal Amazon.

However, studies analyzing the cost-benefit of alternative management practices are scarce. The objective of this study is to compare the cost-benefit of adopting On-Farm Biological Control in relation to Integrated Pest Management (IPM) and Conventional Management in Soybean cultivation, in the region of Maracaju-MS, during the 2022/2023, 2023/2024, and 2024/2025 harvests. Thus, this study intends to assist rural producers in making decisions about which pest and disease management offers the best cost-benefit, in addition to encouraging the scientific community to conduct more economic viability studies on the use of On-Farm Biological Control for pest and disease management. This will contribute to promoting sustainable agriculture with less environmental impact. Above all, this study aims to address the Sustainable Development Goals (SDGs): SDG 02 – Zero Hunger and Sustainable Agriculture; SDG 12 – Responsible Consumption and Production; and SDG 15, which concerns the preservation of life on land.

In this context, short food supply chains (SFSCs) have emerged as a promising alternative by promoting sustainable practices and strengthening the resilience of food systems. In Brazil, despite public policies such as the Food Acquisition Program (PAA) and the National School Feeding Program (PNAE), only a small portion of family farmers effectively participates in these networks, revealing structural and organizational barriers that hinder the expansion of this model. This study aimed to investigate the perspectives, emotions, and feelings of key SFSC stakeholders — including producers, consumers, government representatives, and experts — regarding the factors that facilitate commercialization within these channels. To this end, the Q Methodology was employed, combined with Sentiment Analysis, allowing the identification of viewpoints across seven main factors: Trust in product quality; Optimism about financial return; Hope in government incentives; Cooperative strengthening and structuring of short supply chains; Optimism in the valorization of short chains; Expectation of efficient and sustainable management; and Consumer empowerment. Across all factors, trust emerged as a transversal emotion, followed by other positive and negative emotional responses. A predominance of positive sentiments over negative ones was also observed, reinforcing the symbolic and affective power of short supply chains as spaces for social, economic, and territorial transformation. The findings suggest that strengthening SFSCs requires the development of intersectoral public policies that integrate infrastructure, credit, land access, technical training, and the symbolic valorization of food and its producers. Therefore, it is concluded that SFSCs, in addition to enhancing food system resilience, have the potential to foster fairer, more inclusive, and territorially rooted systems, provided they are structured based on integrated public policies and the cultivation of lasting social and emotional ties.
