The pressure for food production has expanded agriculture frontiers worldwide, posing a threat to water resources. For instance, placing crop systems over hydromorphic soils (HS), have direct impact on groundwater and influence the recharge of riverine ecosystems. Environmental regulations improved past decades, but it is difficult detect protect these soils. To overcome this issue, we applied temporal remote sensing strategy generate synthetic soil image (SYSI) associated with random forest (RF) map HS in an 735,953.8 km2 area Brazil. presented different spectral patterns from other soils, allowing detection by satellite sensors. Slope SYSI contributed most prediction model using RF cross validation (accuracy 0.92). assessments showed that 14.5% study represented HS, mostly located inside agricultural areas. Soybean pasture areas had up 14.9% while sugar cane just 3%. Here present advanced technique may improve identification under assist public policies their conservation.

Brazil's environmental legislation obliges private properties to retain a fixed proportion of their total area with native vegetation, the so-called "Legal Reserves". Those areas represent practically one third country's vegetation and are well known for role in biodiversity protection provisioning wide range ecosystem services landowners society. Despite relevance, this instrument has been criticized by part agribusiness sector its representatives Brazilian Congress. The Legal Reserve requirement is said be too restrictive impede full expansion agricultural activities, thus detrimental development country. Here, we critically analyze arguments employed justification recently proposed bill that aims completely extinguish Reserves. We demonstrate used mostly unsupported data, evidence or theory, besides being based on illogical reasoning. Further, synthesize principal benefits Reserves, including health economic benefits, emphasize importance these reserves water, energy, food, climate securities, addition primary function assisting maintenance landscapes. also highlight Reserves key-component effective less expensive nature-based solutions, should considered as assets Brazil rather than liabilities. Based available sound scientific agreement strongly oppose any attempt weaken

A legislação ambiental brasileira requer que as propriedades privadas mantenham uma proporção de sua área coberta com vegetação nativa, chamadas Reservas Legais. Essas áreas representam praticamente um terço da nativa do país e são reconhecidas pelo seu importante papel na proteção biodiversidade provisão vasta gama serviços ecossistêmicos aos proprietários rurais à sociedade. Apesar relevância, o estabelecimento Legais tem sido criticado por parte agronegócio seus representantes no Congresso Nacional. exigência é considerada demasiadamente restritiva impediria a plena expansão das atividades agrícolas e, conseguinte, prejudicaria desenvolvimento país. Aqui, analisamos criticamente os argumentos projeto lei recentemente proposto, visa extinguir completamente Demonstramos usados não têm apoio em dados, evidências ou teorias, além ser baseados raciocínio ilógico. Além disso, sintetizamos principais benefícios Legais, inclusive econômicos para saúde humana, enfatizamos importância dessas reservas seguranças hídrica, energética, alimentar climática, função primária auxiliar manutenção paisagens agrícolas. Destacamos também componente‐chave soluções baseadas natureza, reconhecidamente mais eficazes menos dispendiosas. Devem, assim, serum consideradas como ativos Brasil, passivos.
