Issues Water Governance What is at stake?

Transformations of Water Policy in Brazil

Water Governance in Macro - Metropolitan So Paulo and SustainableUrban Development

Environmental Stress

air pollution, pollution of waterways, theequation water quantity/water quality

Climate Change Prospects and Water Governance


3/18

Main Principles of Policy

Descentralized management - level of river basin;

Integration of sectorial policies involved in water management;

Involvement of water users and Civil Society in decison makingprocess;

Water as an economic good.


4/18

Process of Participation in Water Governance

National Water Resources Council

Water Resources Councils of the states and the Federal District

Catchments committees 2011 -more than 160

Government agencies with attributes related to water resourcesmanagement

Water agencies


5/18

So Paulo State Water Policy -1991State divided into 22 administrative catchment units

Established criteria for decentralised and participatory

management of water resources through watershed committees.

Metropolitan Region of So Paulo

Alto Tiet River Basin

Water in MRSP- the context

Alto Tiet watershed, which supplies the Metropolitan Region of So Paulo

Considered as one of the most critical areas in terms of water availability;

Supply water demand to almost 20 million inhabitants;

50% of water is transferred from neighboring watersheds;

Sharp demographic growth and urbanization has led to severe problems of

water pollution- demographic growth significantly reduced in last decade.


8/18



The area covered by the Alto Tiete basin is almost coterminous

with the Metropolitan Region of Sao Paulo. With a drainage

area of 5,985 square kilometers (2.4 percent of the state's

territory), the basin encompasses 35 of the 39 municipalities

and 99.5 percent of the population of Greater Sao Paulo.

Population growth today: 1,2% /year

In 2010 the population is estimated in 19, 7 million.


9/18



Massive human occupation was accompanied by the large-scale

construction of water infrastructure, including dams, pumping

stations, canals, tunnels, and inter-basin transfers to and from

neighboring basins.

Alto-Tiete basin is served by a complex hydraulic and

hydrological system. Despite this extensive water infrastructure,

the water availability of the region is still very low (201 m3-hab-

an) and even lower than the semiarid regions of the BrazilianNortheast


10/18



Three key management issues to be addressed in the Alto Tiete

basin:

Water quantity to supply a burgeoning population

Water quality which is deteriorating to a point where water

availability for a range of uses is severely affected

Urban flood control and mitigation represents another major

challenge in the basin.


11/18



Important achievements have been made over the past 15

years

Decentralization process - characterized by the creation of theAlto-Tiete committee and its subcommittees

Financing from the State Water Resources Fund

Need for: measurable physical results such as the improvement

of water quality, rationalization of water use and

reduction/control of floods


12/18

Water and Land Use Issues

Non reduction of floods and impacts on population indicate the lack

of adequate land use planning and dialogue between water

governance authorities and municipalities

Natural causes always prevail in authorities arguments

Existing infrastructure has become insufficient to control and mitigate

Increase of natural events and strength has become common

Lack of adequate disasters prevention policies

Delay in basic infrastructure to flood insecurity

Solutions Needed

Reduce erosion

Control garbage in waterways and brooks

More than 5 million m3 of mud, sand and garbage carried to two main

rivers of the region

Challenge to overcome palliative solutions

Remove irregular occupations has a political cost

Importance of codes and construction norms


17/18

Water Governance and Intersectoral Articulation

Challenges Integration , equipment and mapping to enable quick response

Improve systems of alert

Inform, educate and warn population on extreme events alert

Eliminate rsik areas needs land use control

Restitute, mantain rivers, urban green areas and hillsides

Advise population how to build to mitigate impacts og heavy rains and

extreme events

Many Thanks!!
