Editorial N° 04/2021 Water: An Urgent Matter for Brazil

Brazil is one of the most biodiverse countries of the world (UNEP, 2019), but is going through a serious environmental imbalance, motivated by the current institutional crisis of the Ministry of the Environment (MMA, by its acronym in Portuguese), which has resulted in the reduction of Councils and decision-making bodies of the Ministry, discourses of denial of environmental policies relevance, breakdown of tools and environmental policies (CAPELARI et al., 2020).This is an unprecedented movement that jeopardizes natural resources preservation, wild fauna and flora and the planet. The production of scientific knowledge is key in a moment of misinformation, acting as an important foundation for decision-making, as well as for the development of public policies. [...]we present in this session two articles that were awarded in the International Workshop entitled: II Sustentare e V WIPIS - Workshop Internacional sobre Indicadores de Sustentabilidade, which provide an important discussion on water. [...]sustainability is a multifaceted phenomenon and requires an interdisciplinary construction to create systemic actions to face historical and complex problems (CONTI, 2020;DE BENEDICTO et al. 2020). [...]Municipalities, States, and the Federal Government should treat it as a priority, in order to provide living and development conditions for current and future generations.
