G. de  aErosion control in agricultural production systems in Brazil.h[electronic resource]  c2019  aWith the increase in demand for agricultural and forestry products, the pressure on soil and water resources intensifies, leading to extreme food, nutritional and socioeconomic insecurity in the world. This paper aims to present the political and technological strategies to control erosion in agricultural production systems in Brazil presented during the Workshop - Water on Agriculture: Training the Trainers. Erosion has been causing economic damage and degradation in different regions of the country, mainly over sandy soils and areas used since the first agricultural cycles in the 16th century. The largest land use is occupied by pasture with different levels of degradation. Radical changes in soil management and throughout the production system are required to control erosion and to prevent soil and water degradation. The continental expression of Brazil, housing six biomes with different types of vegetation, relief, soils and climate, in addition to the contrasting socio-economic and cultural aspects, requires that the construction of a national policy for sustainable soil and water development should include adaptations considering territoriality and regional specificities. It is necessary as well to develop information on the potentialities and limitations of soil for agricultural production. A strategy to start solving these problems is being initiated trough the National Soil Mapping Program (PRONASOLOS) with detailed information on the country's soils over the next three decades at the most appropriate scales in order to plan agricultural production in a sustainable manner and to prevent water and soil degradation. Zero tillage systems and agroecological production systems can also be considered as examples for erosion control. To further reduce soil and water losses due to erosion in Brazil, it is necessary to expand the use of more sustainable agricultural production systems considering the different limitations and potentialities of the soil and the socioeconomic and cultural conditions of the country.  aErosion control  aNo-tillage  aPublic policy  aSoil restoration  aSustainable agriculture  aWater conservation  aAgricultura Sustentável  aConservação da Água  aControle da Erosão  aPlantio Direto  aPolíticas Públicas  aProdução Agrícola  aRecuperação do Solo  aSistema de Produção1 aSTUCHI, J.
