Nexus of exclusion and challenges for sustainability and health in an urban periphery in Brazil.

The urban nexus approach involves the investigation and elucidation of integrated solutions through the recognition of tradeoffs between water, energy, and food, namely resources whose shortage leads to inequalities in health. The article's central hypothesis is that the context of shortage corroborates social practices that can be synergic or contradictory in relation to the challenges of sustainability and social rights. The objective is to investigate synergies and contradictions based on social practices in the urban nexus in the neighborhood of Novo Recreio in the city of Guarulhos, Greater Metropolitan São Paulo, Brazil.
