Abstract
Brazil has the highest water availability of any country in the world. Nearly 20% of all the world's rivers flow on Brazilian soil. Brazil's herds of cattle, pigs and poultry are among the largest in the world, and the country uses irrigated agriculture extensively, which accounts for most water consumption (approximately 70% of the water consumed in the world). The Brazilian Agricultural Research Corporation (Embrapa), the largest and most important public institution of Brazilian agricultural research, has attempted to develop environmental technologies in order to minimize the impact caused by the scarcity and pollution of water resources. This paper describes the technologies this institution offers to different regions. For this purpose, a descriptive and exploratory study was conducted in various Embrapa research units. The results showed that research on the rational use of water in agriculture has intensified since the early 2000s. However, the pace of growth in agricultural activities and their impact is much greater than that of the generated technologies, demonstrating the difficulty in striking a balance in this relationship. Furthermore, it is clear that that water scarcity and the increasing pollution of shallow and deep waters are complex issues with no short-term solution.
