Title: Impact of Global Change on the Coastal Areas of the Rio de la Plata: Sea Level Rise and Meteorological Effects


1
Impact of Global Change on the Coastal Areas of
the Rio de la Plata Sea Level Rise and
Meteorological Effects
  • AIACC LA26
  • Argentina

2
Rio de la Plata (physical aspects)
  • Estuary zone formed by the junction of the
    Parana River (16000m3/s) and Uruguay River
    (6000m3/s).
  • Approximately has 300km long and soon reaches a
    50km width that increases until 250km at the
    mouth.
  • The Parana Delta is growing and the coastal zone
    of the San Borombom Bay is retreating by storm
    surges.
  • The flow dynamic is driven by the incoming tidal
    wave, the discharge of the tributaries and the
    wind.
  • The Coriolis effect makes higher levels of water
    in Argentina than Uruguay.

3
Rio de la Plata (socio-economic aspects)
  • Argentina coastal area of the Rio de la Plata
    has the most important concentration of
    population, urban centers, infrastructure and
    services of the country.
  • The total population of the zone is 11000000
    inhabitants, formed by the Buenos Aires City
    (3000000 inhabitants) and the Big Buenos Aires
    (8000000 inhabitants).
  • The rate of urbanization of this area is 97.5
    and the density of population is 1361.7
    inhabitants per km2.

PROJECT FRAMEWORK
  • Impact models
  • Meteorological
  • Hydraulics

Vulnerability Assessment (social aspects)
Risk Assessment FLOODS
Risk Assessment EROSION NEOTECTONICS
Vulnerability Assessment (economic aspects)
Identify ongoing adaptation strategies
Vulnerability Assessment (institutional aspects)
Stakeholder Analysis Intercosultation with
institutions
Risk Analysis COPING RANGE THRESHOSLDS
5
The Current Situation in Argentina

Climate Change is not a priority now. At Policy
Makers level this issue is perceived as a
long-term problem (large time scale). Its
scientists matter.
Our Strategies
Build Scientific knowledge
Analyze how to introduce aspects of the problem
in transversal ways related to
identified ongoing adaptation strategies (Capacity
Building in a broad field)
6
  • How to influence policy makers?
  • The relation with the stakeholders as a
    continuous process vs. contact them with the
    final science report
  • Reinforced the concepts of Adaptation and Coping
    Range to address the problem (inside the project
    and as a strategic approach)
  • Not present the Climate Change as a disaster or
    a catastrophic scenario (add one more problem).

7
Main tools
  • Interconsultation with Stakeholders
    (Institutions)

- Stakeholder as a privileged users and key
informants
- Go beyond isolated consulting to install a
communicative process
  • Risk Assessment

- Considering physical aspects
- Identifying and working with driver forces
- Making a probabilistic approach
