Assessment impact of flood to socio-economics of along Namngum river of Nasaithong and Xaythany districts (1995-2004)by using ECLAC methodology
Presented by Mr. Phetsavang Sounnalath- Director NDMO/Lao PDR
Content of presentation;
project background purpose of assessment implementing technique impact assessment ECLAC methodology lesson learned and recommendation
Map of Nasaithong and Xaythany districts
Project background;
under project cooperation with UNESCAP on using ECLAC methodology to assess the impact of flood to socio-economics of selected areas along Namngum River of Nasaithong and Xaythany districts
the study covered Vientiane Mun. and two districts in general, but focused on 10 target villages.
5 villages of Nasaithong and 5 in Xaythany districts, all are flooded almost every year.
The study had done on 4 sectors; agriculture, health, transport and education
Purpose of assessment
first experiment on using ECLAC to Laos to compare with existing methods to find the gaps
to have more clear picture of flood impact in both sides direct and indirect in order to compare the total losses to development indicators
To build an example from NAMNGUM case and adapt to Laos in general
to build a factors that benefit for planning and persuading decision markers.
Implementation technique
Building assessment team Scope; determine the target area to be studied; 10
villages of two districts along NAMNGUM Four sectors; social, agriculture, transport and
education working on data set up the outcome
The assessment of flood impact
social impact; direct ;the loss of individual person and family income in flooded
year from 30 – 45% indirect; flood changed people habit and occupation forced labor out of their places, many migrated to city or cross
border impacted to people food ration and health exhausted effected people resources put people in debt and make them poorer effected to price of agricultural products psychology impact; nerves and loss confidence……
Flood impact
Agriculture; direct; the impact and loss of paddy field, vegetable
fields, fishponds and livestock indirect; estimated the cost of rehabilitation of
paddy and vegetable fields and fishponds, the cost of purchasing of replacement of poultry and animals
for example; in two study Nasaithong and Xaythany districts 2002

Flood impact to agriculture
Direct loss; (calculation ) Damage cost of agriculture area 1 ha= 3.991.000 kips Damage cost of vegetable area 1 ha = 3.300.000 kips Damage cost of maize field 1 ha = 2.564.000 kips Indirect loss; (estimate) Estimate loss of rice yield 1 ha(4 tons) = 6.000.000 kips Estimate loss of vegetable product 1 ha(3.5 tons)= 5.250.000
kips Estimate loss of maize yield 1 ha(3 tons) = 4.500.000 kips
Flood impact to health sector
The clinics and dispensary of two districts were not seriously effected due to the location facilities are not in risky places
flood created problems; - polluted and shortage of drinking water - damage to sanitation facilities; well, toilets - polluted environment, smelled dirt - born some diseases; diarrhea, foot disease - spending more money for treatment Direct loss; calculation of the cost for repairing wells and toilets Indirect loss; - estimate the cost for buying or transporting drinking water - cost of cleaning houses and other facilities

Flood impact to education sector
Some school were affected by strong wind and rain in flood period, but were not seriously damaged, only number of roofs, tables, chairs, benches and boards had been damaged
the direct cost of damage is estimate the cost of repairing facilities
indirect estimate is based on renting temporally place for school function will awaiting for repair in duration of 10 days (5 classes x 150.000 kips x days)
The total cost of damage for schools in 10 villages is 78.800.000 kips (see table 12 in the report)
Flood impact to transportation and road
Problems; flood affected to roads every year roads to villages had been damaged or cut for
some time increased cost of public and private transport during
and after flood Boards had been used to travel to some areas The direct loss is calculation of repairing or
rebuilding roads Indirect loss is counted upraising price of transport
cost

Experience on using ECLAC
ECLAC provided comprehensive framework for analyzing flood impact to all sectors, it help drawing up full scenario of impact in both ways direct and indirect
provide more accurately factors for persuading decision on countermeasures such as; relief, rehabilitation and reconstruction
example can be used to assess the flood impact to countrywide especially important when it can compare percentage of losses to GDP
the existing method is showed that the current practice of estimation could bring to attention only about 50% of total damages and losses if compare to using an ECLAC method
This is the first time that indirect impact had been counted in assessment in Laos
poor recorded and stored of information in local community made gathered information has low accuracy
No experience and technique on estimating of indirect impact

Recommendation
further adapting ECLAC to Laos at countrywide training on ECLAC NDMO should take the lead propose structural works; building drainage system,
earthen embankment, repairing roads and schools running capacity building activities; improve an
early warning and information dissemination, environmental management, training on disaster reduction
