“…In areas containing annual crops, high concentrations of nutrients and predominantly silt and clay were verified in the soil runoff, which has a strong relation with particle size due to cation exchange capacity [59]. This sediment runoff to the rivers may contaminate the water resources and the aquatic biota [66][67][68][69], which could be consumed by people [70,71], or the water contaminated with pesticides may be used for crop irrigation [72] or distributed to residences for human consumption, as observed by Panis et al [73] studying 127 grainproducing municipalities in Parana State, Brazil, which revealed contamination of drinking water and that contamination may increase the risk of cancer. In the Brazilian Amazon, pesticides were detected in aquatic ecosystems and sediments near a large zone of soybean production in the Santarém region [74], in the surface and ground waters, in drainage sediments in the indigenous lands surrounded by oil palm monoculture [75], and in aquatic and terrestrial ecosystems in the Brazilian Pampa [76].…”

There is an urgent demand to change our intensive crop production systems, replacing them with soil use and management systems that recover, preserve, or improve soil health and are environmentally sustainable, producing healthy and good-quality food. In this work, we compile and present strategies and public policies aimed toward soil and water conservation and food production in Brazil. The results presented may help Brazilian farmers adopt practices to recover, maintain, or improve soil health and politicians to create or modify public policies for healthy soil and food, without the necessity of increasing agricultural areas. Food insecurity was also addressed, with family farming playing an important role in food production and decreasing food insecurity. But these challenges need the combined efforts and engagement of the whole society.

Pesticides are beneficial in protecting crops from pests and improving agricultural productivity; however, concerns on pesticide pollution in water have increased due to their indiscriminate use and lack of adequate regulations. Many studies have focused on the risks of pesticides considering the limited number and types of pesticide residues in crops and soils, and duration, and very few have focused on surface water throughout the year. Therefore, this study comprehensively identified 308 pesticides in surface water samples collected monthly over one year in the Saemangeum Basin, Korea. Both targeted and non-targeted analyses were used to identify 171 and 24 pesticides, respectively. Results highlight the extensive extent of pesticide contamination. Among the quantified pesticides, bromobutide and pretilachlor consistently exhibited high concentrations and risk levels, as indicated by their elevated risk quotient (RQ) values. Seasonal variations in pesticide concentrations revealed distinct patterns with intensified herbicide use during summer and increased insecticide concentrations during autumn. This study highlights the presence, distribution, and associated ecological risks of pesticides in surface waters, emphasizing the necessity of comprehensive monitoring and regulatory measures to protect aquatic ecosystems. The high RQ values identified for specific pesticides underscore the urgent need to implement effective strategies to mitigate these environmental risks.
