A nitrogen footprint perspective for Brazilian water sector

In the process of stablishing a national politics for the water management in Brazil, the linkages between population food, energy and water consumption are rarely mentioned. In this study, we present a perspective for the water sector into Brazilian N-footprint.

Preliminary results show that most of Brazilian federal units have low wastewater N removal factor (< 0.2). With population increase and reduction of investments in sanitation in Brazil due to the economic crisis, N flow could rise and may aggravate the impacts on ecosystems and human health.
