Brazil and Climate Change:

Government Technological Strategies

The technological infrastructure of the state and
municipalities ceased to function because their
structures were underwater. As a result, internal and
external communication was hampered, and decision-
making was hindered by the information generated
during the catastrophe.

During the heavy rains, 471 cities were
affected by floods, more than 200 people
died, over 600,000 people had to leave their
homes and 80,000 people had to stay in
temporary shelters. On average, 95% of the
state's economy was impacted, with $300
million in uncollected taxes.

Thus, Codex and Esri made their technological structure available in ArcGIS to assist in the resumption of
technology use in government structures. Over 30 days, 17 applications were implemented in the operational
flow during the floods. These technologies supported the following government decisions:

Logistics organization of rescues; Visibility of affected immigrants;

Monitoring of dam breaches; Prediction of areas that could be affected by

water levels rising in cities;

Providing an overview of the before
and after of affected areas, facilitating Monitoring of blocked roads
faster reconstruction in the most
impacted regions;
