Physical Background

Project Area: Sao Francisco Project Area: Sao Francisco BasinBasin

The Rio São Francisco basin is the third

largest river basin in Brazil. It covers a

large portion of the so called “Drought

polygon” of Northeastern Brazil,

crossing climatic zones ranging from humid to arid. The Sao Francisco river

has its headwaters in the state of Minas

Gerais but extends to five additional states.

Project Area: Sao Francisco Project Area: Sao Francisco BasinBasinBasin Area: 640, 000 Km² - 8% of

national territory

States covered: Minas Gerais and Bahia (83%), Pernambuco , Alagoas and Sergipe (16%), and Brasilia (1%)

Population: Approximately 13 million people are resident in the basin, principally concentrated in the upper sub-basin.

Land-based activities along the river: mining, agriculture, industry, and urban activities.

Ecological StructureEcological StructureThe basin is divided into Upper, Middle, Lower Middle, and Lower sub-basins, plus the oceanic end point, each with distinct environmental and socioeconomic characteristics.

The estuarine wetlands located at the debouchment of the river into the South West Atlantic form a particularly important environmentally sensitive interface between the riverine and marine environments.The Ecological structure is currently under threat due to unsustainable hydrological and land use management practices within the basin.

Problem Areas

Priority environmental Priority environmental concernsconcerns

•Land degradation, erosion, and desertification,

•Water contamination by organic pollutants and heavy metals,

•Modification in the freshwater, estuarine, and marine fauna and flora.

Specific Problem AreasSpecific Problem Areas

Upper Sub-basin:

•Direct discharge of untreated municipal and industrial effluents

•Widespread use of agrochemicals

•Deforestation

•River Contamination

•Impact on fish and aquatic fauna

Lower-Middle sub-basin:

•Water quality

•Contaminant deposition of reservoirs

•Impaired fish migration

•Soil erosion

•Impact on fish and aquatic fauna

•Modification of river basin and estuarine geomorphology

•Contamination of Surface

Lower sub-basin:

•Sedimentation

•Eutrophication in the reservoirs

•Oligotrophication of coastal waters

•Alteration of river flow regimes

•Reductions in numbers and diversities of fish populations and other endangered species

•Increased incidence of endemic diseases

Project GoalsProject Goals

•Assist the government of Brazil to incorporate land-based environmental concerns into development policies, plans, and programs for the Basin and for the protection of its coastal zone,

•Develop a Watershed Management Program (WMP) for the São Francisco River Basin.

Expected ResultsExpected Results

•Improved river basin and coastal zone environmental concerns, increased public and scientific awareness and knowledge within the basin and its coastal zone,

•Improved public and stakeholder participation through hands-on type involvement in communities in the remedial measures,

•Improved organizational structure and staffing capabilities needed to implement financial mechanisms for water rights and water charges,•Improved quantification of water use, use conflicts and hydrological management.

•Improved integrated management and environmentally sustainable development of SFRB,
