“…The introduction of genetically modified cultures in Brazil, mainly soybean, different from the expected, accounted for the increase of pesticide usage in the country (Almeida et al, 2017). Glyphosate is the main pesticide used as complementary input to genetically modified soybean and its usage was broadened, as well as the outspread of the soybean culture in Brazil (Dias, Rocha & Soares, 2019). Data provided by IBGE (2023) has shown the relevance of soybean for the Brazilian agricultural economic performance.…”

Pesticides have been used for a long time in agriculture to prevent the growth of undesired organisms. However, depending on the type of production (i.e., conventional, organic, and regenerative), they might not be applied. Adequate types and uses of pesticides should not cause any damage to any non-target species or environments due to the exposure to it, especially if all farming operations have been done properly. Reversely, when pesticides are applied in inappropriate time, amount or technique, they may cause several impacts, among which is water contamination. Brazil stands out worldwide for its agricultural potential, but it is exposed to risks concerning the water supply security to its population. The current study is a comparison of the Maximum Permissible Concentrations (MPC) for pesticides in potable water supply in Brazil with the values set in the United States, Canada, European Union countries, Japan, and the guidelines issued by the World Health Organization. The regulations of each country were used, as well as the trading, consumption and agricultural production data. The Brazilian regulation is the one accounting for the largest number of pesticides. However, their MPC is 5,000 times more permissible than that from the European Union for the herbicide known as glyphosate, 300 times than that for 2,4-d and 20 times than that for atrazine. Finally, it was possible to observe the relevance of revising the regulation and public policies in place to minimize the indiscriminate use of pesticides in Brazil and adapt these compounds to the standards in a global level.

“…Além disso, a contaminação das águas por agrotóxicos é outra questão relevante. As bacias hidrográficas de regiões com uso intensivo de agrotóxicos tendem a estar contaminadas, afetando a população do entorno (Dias, Rocha, Soares 2019). Não apenas isso, observamos dificuldades de monitoramento e controle dessas doenças entre os pacientes diagnosticados.…”

“…Recently, some studies raised concerns about the soybean system of weed control, challenging the idea of the social and environmental benefits of the usage of glyphosate in GM crops ( Dias et al, 2019 ). After 25 years following the initial GM diffusion, environmental concerns, and some critics of the performance of GM cultivars, are still in place, even in countries like Brazil and Argentina, which are highly competitive in soybean, corn, and cotton.…”

Genetically modified (GM) seeds have had relevant impacts on worldwide agriculture, even with a limited number of essential traits launched in the markets. The focus on platforms crops has favored the combination of traditional breeding, GM insertion, and diffusion in agriculture. One of the remarkable features of the GM traits has been the close link with pest and weed control systems. We investigate the environmental effects due to pesticides for two different GM seeds: insect resistant (IR) cotton and herbicide tolerant (HT) soybeans in a particular period of Brazilian agriculture, 2009–2013. We use a dataset on commercial farms' use of pesticides and biotechnology in Brazil to document environmental effects of GM traits. We explore within farm variation for farmers planting conventional and GM seeds to identify the effect of adoption on the environmental impact of pesticides measured as the quantity of active ingredients of chemicals and the Environmental Impact Quotient (EIQ) index. The findings show that the IR trait reduces application of insecticides by 22% and the associated environmental impact by 20% the environmental impact of insecticides. However, for HT traits, we find that application of herbicides increases by 55.8% and the associated environmental impact by 44.4%, showing a significant increase in the EIQ. The HT results are driven by an increase of less toxic herbicides elevenfold larger than the decrease in less toxic ones, which we interpret as evidence of weak substitutability between herbicides of different toxicity levels. Addressing what happened in the last decade, the paper also presents a view of the transformations in GM usage in Brazil, focusing on the considerable success in adopting stacked genes. Future perspectives point to a more diversified menu of technologies, crops, and adopting countries, going beyond platform crops and more prominent agriculture exporters.
