With 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.

Heat stress is an important issue in the global dairy industry. In tropical areas, an alternative to overcome heat stress is the use of crossbred animals or synthetic breeds, such as the Girolando. In this study, we performed a genome-wide association study (GWAS) and post-GWAS analyses for heat stress in an experimental Gir × Holstein F2 population. Rectal temperature (RT) was measured in heat-stressed F2 animals, and the variation between 2 consecutive RT measurements (ΔRT) was used as the dependent variable. Illumina BovineSNP50v1 BeadChip (Illumina Inc., San Diego, CA) and single-SNP approach were used for GWAS. Post-GWAS analyses were performed by gene ontology terms enrichment and gene-transcription factor (TF) networks, generated from enriched TF. The breed origin of marker alleles in the F2 population was assigned using the breed of origin of alleles (BOA) approach. Heritability and repeatability estimates (± standard error) for ΔRT were 0.13 ± 0.08 and 0.29 ± 0.06, respectively. Association analysis revealed 6 SNP significantly associated with ΔRT. Genes involved with biological processes in response to heat stress effects (LIF, OSM, TXNRD2, and DGCR8) were identified as putative candidate genes. After performing the BOA approach, the 10% of F2 animals with the lowest breeding values for ΔRT were classified as low-ΔRT, and the 10% with the highest breeding values for ΔRT were classified as high-ΔRT. On average, 49.4% of low-ΔRT animals had 2 alleles from the Holstein breed (HH), and 39% had both alleles from the Gir breed (GG). In high-ΔRT animals, the average proportion of animals for HH and GG were 1.4 and 50.2%, respectively. This study allowed the identification of candidate genes for ΔRT in Gir × Holstein crossbred animals. According to the BOA approach, Holstein breed alleles could be associated with better response to heat stress effects, which could be explained by the fact that Holstein animals are more affected by heat stress than Gir animals and thus require a genetic architecture to defend the body from the deleterious effects of heat stress. Future studies can provide further knowledge to uncover the genetic architecture underlying heat stress in crossbred cattle. MenosHeat stress is an important issue in the global dairy industry.
