Dairy cattle farming is a water-intensive activity. There is partial knowledge among actors in the national dairy sector, the academic community and public institutions about the use of water by the activity. Therefore, it is necessary to generate information and knowledge so that the use of water resources in the activity is carried out considering good environmental practices. Water management in dairy farming will provide better efficiency in the use of the resource and greater resilience of the activity in the face of environmental and climate challenges. Water consumption in the production unit must be quantified by production system and type of use. From this quantification, indicators of water efficiency and productivity can be generated in order to identify inefficiencies in the use of the resource and the risks that the activity is exposed to in the face of climate scenarios. The objective of this project is to promote water management in dairy farming through the use of good production practices and decision support tools, which will contribute to the conservation of the natural resource in quantity and quality.
