L.  aWater use efficiency and supply in agricultural production.h[electronic resource]  c2020  acap. 4, p. 37-48.  a(Sustainable Development Goal, 6).  aThis chapter discusses aspects related to the water-use efficiency in irrigated agriculture and animal production, as well as possibilities to use rainwater as a way to reduce the effects of regional climate irregularities, and alternatives to using brackish/saline water, constituting a strategy of utilization of available water resources. This information, expressed in the form of knowledge and technologies generated by Embrapa, has the potential to contribute to the achievement of target 6.4, which seeks, by 2030, to substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity, and substantially reduce the number of people suffering from water scarcity.  aAnimal production  aWater quality  aAgricultura  aÁgua  aBarragem Subterrânea  aCisterna  aPoluição da Água  aProdução Animal  aQualidade da Água  aAgricultura irrigada  aÁgua da chuva  aUso eficiente1 aBRITO, L.
