II) Sustainable water management:some of these BPs are already under implementation in government programs, generating benefits, inter alia, improved water security, better quality of consumption water, less work for family nuclei, particularly women and children.
Cisterns for consumption (from roof runoff);
Cisterns for production (from roof or ground runoff);
Rain-fed waterholes (barreiros);
Trench tanks (barreiros trincheira) (improve water conservation – maximum deepness and minimum area of superficial layer to avoid water losses by evaporation; water for production, livestock maintenance and water security, associated to water diversion techniques to avoid advanced erosion);
Stone tanks or caldrons;
Drip and micro-aspersion irrigation (Xique-Xique system) (water management technique which improves water infiltration, preventing water losses due to evaporation and avoiding soil salinization process).
