Some conclusions

Conceptual Framework: Social Vulnerability, Environmental Risk and Disasters

The SV – Social Vulnerability is one of the four dimensions of the environmental risk. Other dimensions are hazard, exposition and uncertainty.

It is defined by social, economical, cultural and institutional conditions of a society, previous of a disaster event, that put this society in conditions to suffer or avoid damages (of different kinds: economical, physiological, on health, etc.).

SV will determine the levels of difficulties and capacities of each social group to recover by itself after the stress and the impacts.

SV: Issues Researched

Elaboration of a social vulnerability index (SVI) for the study area.

Identification of people (number) that could be affected in a direct way.

Analysis of land use and inventory of assets/infrastructure that could be directly affected.

Case studies: La Boca/ Avellaneda.

La Boca Neighborhood (1)Some characteristics:Some characteristics:

One of the oldest city’s neighborhood, it was born as harbor in a marshy area. Since its beginnings, it has always been a marginal area, although the current urban renewal projects. Total population (DGE, 2001): 39.396 inhabitants. Area : 3,3 km2. (1,29% of CABA) Density: 11.938 inhab/km2

(1,65% of CABA). Main hazard: floods by “sudestadas” and intense rainfall.

La Boca Neighborhood (2)Afectable area and population (under 5 meters): 100 % of the neighborhood.

Some limitations of the disaster management:

A false feeling of security settles down from the building of defense engineering works (“hidden” risk).

There are communicational disadjustments among the involved institutions themselves, and between them and the population.

There are registered distrustfulness / rivalry attitudes among institutions.

Both, the urban and the floods management, are unarticulated.

In the projected works (coastal defense) the sea level rise

hypothesis is not considered.


Positive aspects:

New non structural interventions are being developed.

There is a strong social participative tradition in the neighborhood, with a particular cultural profile.

There are recent institutional changes in the Municipal organigram: Urban Planning and Public Works are under the same office.

Avellaneda Municipality (1)

Some characteristics:

One of the oldest population centers near the city of Buenos Aires, located on a flooding area.

It has an industrial profile from its beginning as a town (1840).

High levels of urbanization (> 90%, from 1940). Total population (CNPHyV, 2001): 328.980 Area: 55 km2. Population density: 5.993 inhabitants/km2. Main hazards: floods and contamination.

The main institution in charge of disaster's management is the Civil Defense Municipality Board - Junta Municipal de Defensa Civil (JMDC), integrated by:

Mayor (as President); Director of Civil Defense (as Secretary); Government Secretaries –of Health, Social Action, etc.-

(as vocals); Voluntary Fire Brigade (as vocal); Naval Prefecture of Dock Sud (as vocal); Red Cross -Villa Domínico office- (as vocal); and Social Entities’ Leaders, such as Boy Scouts (non

permanent vocals).


Limitations in the flood disasters management:

Lack of continuity in the Civil Defense policies. For example, the Director office, main coordinator of the JMDC, is political and is renewed with each government every four years, or less;

In reality, neither the vocals nor the other representantives of the civil society participate in the JMDC. The decisions on this subject are only in the Civil Defense Director’s hands;

There is no enough risk and disaster communication from Civil Defense to the inhabitants.

There are registered distrustfulness / rivalry attitudes among institutions.


Positive aspects:

Since December 2003, the new Municipal Authorities have designed a new Civil Defense Director. He has a deeper knowledge on disaster management (Chairman of the Volunteer Firemen Federation of Buenos Aires Province);

There is a more intensive coordination by the emergency institutions (Volunteer Firemen, Red Cross and Navy Police) through periodical disaster simulations;

There is highly trained and experienced personnel in some of the institutions;

Some conclusions

In the future, both the inhabitants quantity and the area that could be affected are important.

Floods are a problem nowadays.

There have been successful works as the coastal defenses in La Boca against the “sudestada”. Nevertheless, there are still some areas that continue being flooded.

Some conclusions

An important group of historic neighbors has developed some alternative daily strategies (cultural aspects) that reduce the social vulnerability: • existence of informal warning, self assistance and

evacuation networks, among the neighbors; • choice of adequate building systems;• high sense of belonging and identification with their

place;• experience on what to do in face of floods, etc.

Some conclusions

The public measures for “floods management" are apart from the global urban environmental policies.

This fragmentation of policies and measurements increases the social vulnerability and generates high degrees of uncertainty, that amplifies the damages of each disaster.

Some conclusionsThere are formal obstacles among

institutions: • lack of communication, coordination and

articulation;

• scarce planning;

• the successful programs and projects have no continuity with each change of government.

Thus, the institutions and their policies are not sustainable in time.

Some conclusions

The institutions management style, typical of the national culture, is not adequate for long term processes.

Up to now, both the executed, in execution an projected mitigation plans, and the communication processes to the public do not consider the changes implied by the sea level rise.

Thank you!
