This paper is an attempt to identify and analyze the main challenges of the integrated water resources management in the Brazilian semi-arid region. Some local peculiarities are pointed out: precipitation 650 mm, runoff variation coefficient of 1.4, evapotranspiration almost 2000 mm, intermittent rivers, drought frequency > 20% and reservoirs efficiency about 25%. The basic challenges are discussed in a regional context: dam safety, integrated planning, institutional coordination, water as an economic good, environmental control, institutional capacity, community participation, water ownership and permits, extreme events and risk management. Strategic action lines and conclusions are finally presented, such as: need to implement a regional water management system, improvement of the hydraulic infrastructure, optimization of water uses and human capacity-building.
