WATER-ENERGY-FOOD
NEXUS IN BRAZIL
AN OVERVIEW
November 2014
João Gilberto Lotufo ConejoANA – National Water Agency
5,565 municipalities - in 27
States
160.9 million inhabitants in
urban areas (2010 Census):
84% of the total population
Area : 8.51 million km2
Federal Constitution (1988):
BRAZIL
“Art. 21. The Federal Government is
responsible for establishing a
national water resources
management system and defining
criteria for water permits”
THE NATIONAL WATER MANAGEMENT SYSTEM -
SINGREH
• Institutional complexity:
– Different levels and organizations;
– River basin x territorial/economical borders.
• Double dominion of water: states and federal
• The role of ANA in the System:
– Implementation of the National Water Resources Policy;
– Management of federal rivers.
WATER
ENERGY FOOD
Background conditions:
• Huge dimensions and
diversity
• A lot of water
• A lot of land
• A lot of energy
• High Urban population
growth
• High Demand for
infrastructure
• Changing conditions

THE NEXUS PERSPECTIVES AND CHALLENGES
• irrigated land and water demand
• urban supply demand
• demand for hydroenergy
• uncertanty on water availability
(climate change and variations)
• water security
• investiment in infrastructure for
water reservation
• investiment on rational water use
• RECONCILING WATER USE CONFLICTS AND LOCAL x NATIONAL INTERESTS
• COORDINATION OF SECTORAL PLANNING AND ACTIONS WITH THE WATER AGENDA
