Thank you for your attention!
**Add graph with publications vs time**Most of the gray water contributions in Brazilian ethanol production come from the processing phase rather than the sugar cane cultivation phase. However, Sao Paulos poorest have little access to quality monitored waterways- thus depend on polluted waters or resort to depleting groundwater sources. Exploring water quality- has management implications/opportunities. How much is being leached, can water be re used in the processing phase (Brazilian ethanol industry is pursuing this cost effective and environmentally advantageous avenue).Other countries- endowments in water resources are not equal as are regulations/enforcement over water quality- ethical dilemmas on the right to water vary. Brazil is well-endowed in water resources but countries like India are not. Choices in water allocation heavily dependent on ethical and social obligations of government.***- NGOs- changing consumption behaviors?***
