BRAZILIAN SCIENTIFIC PROGRAMS IN NATURAL DISASTRES BRAZILIAN SCIENTIFIC PROGRAMS IN NATURAL DISASTRES Presentation Transcript

  • BRAZILIAN SCIENTIFIC PROGRAMS IN NATURAL DISASTRES Dr. Celia Regina de Gouveia Souza Geological Institute - Environmental Secretariat of the State of São Paulo – Brazil Department of Physical Geography – Unversity of São Paulo – Brazil (celia@igeologico.sp.gov.br)
  • Natural Disasters in Brazil In the last few decades, natural disasters have been increasing in magnitude, frequency, complexity, and socio-economic impacts in Brazil. In 2008 it was the 10th country most stricken, when at least 2 millions of people in 831 counties were affected. Objective : assessment on Brazilian scientific research groups officially registered in the National Council of Technological and Scientific Development (CNPq), focusing on: year of foundation , federal state of origin , kind of institution , professional formation , and principal themes of research and actuation .
  • Natural Hazards in Brazil (1) coastal erosion; (2) severe storms and winds; (3) storm surges; (4) drought; (5) dune movements; (6) salinization/saline soil; (7) floods (ordinary, flash, fords, coastal inundation); (8) continental erosion; (9) siltation (lakes, rivers, ponds and reservoirs); (10) karst subsidence; (11) mass movements (landslides, rock falls and flows); (12) expansive soils and rocks; (13) soil liquefaction; (14) collapsible soils and yielding; (15) freeze/frost; (16) wildfire (forests and peats); (17) desertification; (18) natural toxic compounds in soil and water; (19) natural radioactivity; (20) seismic activities (earthquakes, ground shaking); (21) extreme temperatures (heat and cold waves); (22) epidemics; (23) insect infestation.
  • Natural Disasters in Brazil ( recorded between 1948 and February/2010)
  • Scientific Research Groups in Natural Disasters (Year and State)
  • Scientific Research Groups in Disasters (Year and State)
  • Scientific Research Groups in Disasters (Professional Formation)
  • Scientific Research Groups in Disasters (Research and Actuation)
    • The number of RG is considerably higher in the SE (SP, RJ, MG) and S (PR, SC, RS) regions: 72% of the RG (18 groups). They were 7 groups until the 1980s and raised up to 18 new groups in the last two decades (9 new groups per decade).
    • These states are the most populous; include 8 huge metropolitan regions; have had the most catastrophic natural disasters; flood, mass movements and severe storms/winds have consubstantially increased in the last two decades; have the most important Brazilian and Latin American centers of scientific research (SP, RJ and SC).
    Conclusions
    • Flood, coastal erosion and other impacts of climate changes (extreme temperature, storms, drought and epidemics), as well as risk management, have become very important issues in the last years.
    • However, only a few of those 25 RG are currently able to develop researches about them.
    • Lack of perception, need for new professionals/recycling, groups still bad structured, and/or no actualized databases seem to be the explanation.
    Conclusions
