-
0:04 - 0:07Floods and Landslides.
-
0:10 - 0:19Flash floods are usually of rapid onset either
from rain or structural failure. -
0:19 - 0:25Brief duration, associated with steep terrains,
or canyons, or valleys. -
0:25 - 0:31There is little or no warning, and mortality
may be high. -
0:34 - 0:43River floods are usually slow onset but of
long duration, associated with low lying, concave -
0:43 - 0:50terrains, especially with people settling
in these areas, they usually provide some -
0:50 - 0:55warning.
-
0:55 - 1:09Floods account for 40% of all world disasters,
and cause the most damage worldwide. -
1:09 - 1:18These are the most lethal floods that have
occurred in modern history. -
1:18 - 1:26In Uganda, as in other countries in Eastern
Africa, floods are an emerging public health -
1:26 - 1:27problem.
-
1:27 - 1:33Every year, floods affect more and more people
in different localities. -
1:33 - 1:41They are closely associated with heavy rains,
that is natural causes, and human settlement -
1:41 - 1:47patterns, technological causes.
-
1:47 - 1:57An example of Uganda, floods occurred in Bududa, 2010,
Butalejja, 2010, Kisoro, 2010, Soroti, 2007, -
1:57 - 2:05Kumi, 2007, and they occur in
Kampala every year. -
2:05 - 2:15Landslides can be predicted and risk reduction
and mitigation activities can be initiated. -
2:15 - 2:22Factors that contribute to floods include
topographical makeup of the area, and then they -
2:22 - 2:28may accompany other disasters like heavy rains
and river surges, breakdown of river embankments, -
2:28 - 2:40hurricane sea surges, earthquake-related tsunamis,
landslides or volcanic eruptions. -
2:40 - 2:49Natural factors include geological factors,
seasonal variations, climatic factors, and -
2:49 - 2:51topographical factors.
-
2:51 - 2:59Human factors include urbanization, deforestation,
over-grazing, improper construction, and inadequate -
2:59 - 3:05safeguards.
-
3:05 - 3:13Most deaths occur in flash floods, and most
deaths are due to drowning. -
3:13 - 3:26Death rates vary according to country, rate
of onset and community resilience. -
3:26 - 3:31Public health impact of floods includes medical
and public health needs that persist for many -
3:31 - 3:38months after the river floods, normal health
care delivery may be disrupted, chronic illness -
3:38 - 3:41may be worsened in the long run.
-
3:41 - 3:50However, serious infectious diseases are usually
rare in flood and landslide situations. -
3:50 - 3:57Water and food shortages often develop.
-
3:57 - 4:07Key health issues and safety response issues
after floods include water quality, food safety, -
4:07 - 4:15cleanup activity and safety, sanitation and hygiene,
disease vectors, chemical hazards, mental -
4:15 - 4:23health for responders and victims, temporary
settlement, and early warning for subsequent -
4:23 - 4:26floods.
-
4:26 - 4:33Outreach support after floods.
-
4:33 - 4:34Not all victims can seek help.
-
4:34 - 4:43They could be closed off due to geographical
limits, monetary limits, or disability. -
4:43 - 4:50Prevent convergence on limited resources,
set up search and rescue efforts, set up immediate -
4:50 - 4:59relief efforts, enhance surveillance
and situational awareness. -
4:59 - 5:03Prevention and control measures for floods
include mitigation, surveillance and early -
5:03 - 5:12warning, rapid needs assessment, mechanisms
for search and rescue, mechanisms for immediate -
5:12 - 5:21control of water surges, public information,
floodplain management, and responsible management -
5:21 - 5:25of human settlements.
-
5:25 - 5:30Landslides.
-
5:30 - 5:37In Uganda, as an example, landslides are a
focal problem in areas that have topographic -
5:37 - 5:39risk.
-
5:39 - 5:45Due to population pressures and land-use implications,
people are moving higher and higher into high -
5:45 - 5:49risk areas.
-
5:49 - 5:58Landslides can be predicted and risk reduction
and mitigation activities can be initiated. -
5:58 - 6:04Secondary disaster can be caused by landslides
and these include fires and explosions, building -
6:04 - 6:14collapse, dam failures and floods, and release
of toxic materials. -
6:14 - 6:21Contributing natural factors include geophysical
factors, topographic factors, and meteorological -
6:21 - 6:26factors.
-
6:26 - 6:37Manmade factors include structural factors
like types of houses, land-use patterns, demography, -
6:37 - 6:43and population pressures.
-
6:43 - 6:50Health impacts of landslides may include minor
injuries and lacerations, crush injuries to head -
6:50 - 6:59and chest, hemorrhage, bleeding, and hypovolemia,
asphyxia, and drowning, and burns. -
6:59 - 7:06Delayed impacts include dehydration, environmental
exposure, the crush syndrome in people who -
7:06 - 7:18are severely crushed, wound infection and sepsis,
and smoke and dust inhalation. -
7:18 - 7:24Landslides do not often create significant
outbreaks of new infectious diseases because -
7:24 - 7:30of the wash-out affect.
-
7:30 - 7:34Prevention and control measures for landslides
include avoiding construction in areas of -
7:34 - 7:44high geological risk, safer construction,
drills, scenarios and planning in areas that -
7:44 - 7:53are landslide prone, planning for displaced
populations, planning for emergency services, -
7:53 - 8:00and planning for search & rescue.
-
8:00 - 8:03Saving lives.
-
8:03 - 8:05Landslides have potential to cause
Mass Casualty Incidents (MCIs). -
8:05 - 8:13There is need for rapid assessment of impact,
timely and appropriate disaster response, surveillance -
8:13 - 8:20for injuries and diseases, dissemination of
public health information, environmental health -
8:20 - 8:24and control measures, and follow up epidemiology.
