LESSONS LEARNED FROM PAST NOTABLE DISASTERS KAZAKHSTAN PART 1: FLOODS Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA

NATURAL HAZARDS THAT HAVE CAUSED DISASTERS IN KAZAKHSTAN FLOODS DUST STORMS EARTHQUAKES WILDFIRES ENVIRONMENTAL CHANGE GLOBAL CLIMATE CHANGE HIGH BENEFIT/COST PROGRAMS FOR BECOMING DISASTER RESILIENT GOAL: PROTECT PEOPLE AND COMMUNITIES
3
Natural Phenomena that Cause Disasters Planet Earth’s atmospheric- hydrospheric- lithospheric interactions cause: FLOODS

KAZAKHSTAN
5
Kazakhstan has many communities that are at risk from flooding from its 8,500 small and large rivers (e.g., the Ural, Emba, Syr Darya, Irtysh, Ischim and Tobol—the largest).

FLOOD HAZARDS (AKA POTENTIAL DISASTER AGENTS ) TOO MUCH WATER DISCHARGED WITHIN THE DRAINAGE SYSTEM TO BE ACCOMMODATED NORMALLY IN THE REGIONAL WATER CYCLE EROSION SCOUR MUDFLOWS
9
EACH FLOOD HAZARD IS A POTENTIAL DISASTER AGENT
10
A DISASTER CAN HAPPEN WHEN THE POTENTIAL DISASTER AGENTS OF A FLOOD INTERACT WITH KAZAKHSTAN’S COMMUNITIES
11
LOSS OF FUNCTION OF STRUCTURES IN FLOODPLAIN FLOODS INUNDATION INTERACTION WITH HAZARDOUS MATERIALS STRUCTURAL/CONTENTS DAMAGE FROM WATER WATER BORNE DISEASES (HEALTH PROBLEMS) EROSION AND MUDFLOWS CONTAMINATION OF GROUND WATER CAUSES OF RISK CASE HISTORIES
12
A DISASTER is --- --- the set of failures that overwhelm the capability of a community to respond without external help when three continuums: 1) people, 2) community (i.e., a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g., floods, earthquakes,..) intersect at a point in space and time.
13
Disasters are caused by s ingle- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.
14
THE REASONS ARE... When it does happen, the functions of the community’s buildings and infrastructure will be LOST because they are UNPROTECTED with the appropriate codes and standards.
15
THE REASONS ARE... The community is UN- PREPARED for what will likely happen, not to mention the low-probability of occurrence— high-probability of adverse consequences event.
16
THE REASONS ARE... The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.
17
THE REASONS ARE... The community LACKS THE CAPACITY TO RESPOND in a timely manner to the full spectrum of expected and unexpected emergency situations.
18
THE REASONS ARE... The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either the current experience or the cumulative prior experiences.

FLOODS IN SOUTH- KAZAKHSTAN OBLAST FEBRUARY 2012 SPRING RUNOFF AFTER A HARSH WINTER EXACERBATED THE FLOOD RISKS IN KAZAKHSTAN
20
Early warming and heavy rainfall caused snow melt to flood 12 regions and 226 villages.
21
FLOODING IN SOUTH- KAZAKHSTAN OBLAST: FEBRUARY 2012
22
The South-Kazakhstan oblast asked the Government for help.
23
1,100 people were evacuated.
24
IMPACTS According to reports, restoration of the function of all the impacted infrastructure required 1.2 billion tenge ($8 million). Construction of 4 major bridges required 350 million tenge ($2.3 million).
25
IMPACTS (continued) 90 million tenge ($609 thousand) were needed for 30 smaller roadway passes made of pipes. 15 million tenge ($101 thousand) were needed for restoration of roads.
26
Flood damage in South- Kazakhstan oblast exceeded 1 billion tenge ($8 million)
27
FLOODING IN KAZAKHSTAN MARCH 2010 SPRING RUNOFF AFTER A HARSH WINTER INCREASED FLOOD RISKS
28
30+ people died in floods in the south of Kazakhstan as heavy rains and melting snow resulted in the undercutting and bursting of the Kyzyl- Agash reservoir dam in the Alma-Ata region
29
As a result of high water in the region, railway travel ground to a halt, highways were sealed off, and search and rescue operations were accelerated.

FLOODING IN KAZAKHSTAN
33
Kazakhstan’s President, Nursultan Nazarbayev, ordered a government commission to be set up, and initiated actions to clean up the damage and provide support for the flood victims.

THE ALTERNATIVE TO A FLOOD DISASTER IS FLOOD DISASTER RESILIENCE
