4. CALI: LA INVENCIÓN DE UN FUTURO CON AGUA.

En Cali, cada fin de semana decenas de miles de personas acuden a una lúdica del agua al aire libre.

CALI Y SUS VALORES ENDÓGENOS: LA CULTURA DEL AGUA.

Cali, the city of the seven rivers

– Lack integral vision and long time vision

– The basin is not the analysis unit

– Lack leadership and limited institutional coordination

– Limited participation of the communities

– Resistance to change of new concepts

– Problems related to information management

Cali and upper basin of the Cauca River Main problems of water sector

3

– Limitation in the capacity building

– Limited follow-up and control

– Lack articulation between norms, policies and decision

making.

– Vision only in the short term

– Only “end of the pipe solutions”

– Only point source pollution (diffuse pollution is not

considered)

Cali Learning Alliances - Background • Univalle had been in the past important experiences

in water sector projects with several city stakeholders.

• Through these projects, the Universidad del Valle managed to establish close relationships with some of the key stakeholders in water management in Cali and the Cauca river basin

• Experiences in several projects with IRC and UNESCO – IHE

Univalle in SWITCH Project (1)

• 2006 SWITCH Project started. • 2007 (WP 1.1; WP5.3) Univalle started activities in SWITCH Project. Preparing to become a demonstration city. A start is made with the situational assessment and stakeholder mobilization. • 2008 (WP 1.1; WP5.3; WP6.2) -Formal start as demonstration city, with the establishment of the LA (3 topics) -Preparation for the planning processes -First city assessment.

7

Univalle in SWITCH Project (2)

2009 (WP 1.1; WP5.3; WP6.2) Vision and strategic planning, the inclusion of the results of research in this, and the first seizing of opportunities for policy advocacy. 2010 (WP 1.1; WP5.3; WP6.1; WP6.2) -Start of scaling up, by extending the LA to new groups of stakeholders, -Participation in formal planning procedures. -Dissemination and engagement with decision-makers.

LA - Cali City - Participants

• Stakeholders

• Univalle: Lecturers and other professionals from different disciplines

• Students: PhD, MSc, undergraduate, Internship

(Univalle and others)

• IRC, UNESCO – IHE

LA Cali City - Focus • Shift paradigm in waste water management . From the focus in WWTP to a

holistic view of pollution control

• Cali demonstration city, urban area in the context of the upper basin of the Cauca River.

• 3 topics:

– The water quality of the Cauca River and its impact on the water supply system of Cali.

– The southern drainage system of Cali city.

– Expansion area and the possibility of including SWITCH approach.

• Holistic view (WP1.1); Applied research (WP5.3) Learning Alliances (WP 6.2); Governance (WP6.1)

Vision for Cali in 2040

“Cali is a city where all citizens can enjoy a clean and healthy environment, having vital eco-systems and offering extensive green areas in the urban area. The city’s water resources are of good quality, maintain sufficient flow to preserve aquatic life, and are the source for different human uses. There is a safe environment for healthy coexistence in an atmosphere of respect, peace, awareness and environmental culture, where citizens have a decent home and live in areas with low risk for natural disasters”.
