    Semi- Arid Problem

    Low rain levels, concentrated on 3 months Evaporation much greater than the precipitation Adverse geologic characteristic (Crystalline Rocks)

    Need for reservation, with adequate water resources management

    THE DROUGHT

  • Ministry of Environment

    ANTECEDENT CONDITIONS FOR DROUGHT MANAGEMENT

    CONCEPT: centered on emergency and focusing on drought combat;

    INSTRUMENTS: work forces, food and water stamps + water infrastructure without management;

    PROBLEMS: local politics interference, maintenance of high deficits, no preparedness for the next drought and high public investments

  • Ministry of Environment

    THE NEW STRATEGY

    Water Infrastructure + Water Resources Management

    Instruments: Strengthening of water resources institutions implementation of IWRM planning civil works

  • Ministry of Environment

    PROAGUA World Bank loan BR 4310

  • Ministry of Environment

    PROAGUA Water Resources Management Component

    State Water Management Institutions implemented (Cear, Bahia, RN) ;

    Water Laws developed in all states;

    State Water Resources Plans developed in all States;

    Training of Technical Staff;

    Hydrologic Monitoring systems improved;

    Water permit systems and water charges implemented.

    CONCLUSIONSCONCLUSIONS

    Policies should take into consideration the specificity of supplying water to medium and large human settlements and to the rural disperse population

    Socio-economic development of the NE region of Brazil requires both: water resources infrastructure development and local government involvement

    Strengthening of the State water resources institutions is a basic requirement for the sustainability of the water infrastructure

    Success of PROAGUA suggests that the methodology could be pursued in other regions with similar climatic and social characteristics
