^GENERALINFORMATION

1.1.

INTRODUCTION

Due

to

rebel activities which lasted for eight years, there was constant interruption of aerial larviciding in Sierra Leone. Treatment was completely suspended since March ^1997.

The Joint Programme Committee (JPC) approved in December 1998 the recommendation of the Expert Advisor Committee (EAC) to stop definitively larviciding in Sierra Leone.

ln the Western zone aerial treatment was completely suspended during weeks 14,15 and 52 due to ^good entomological results.

ln order to reduce ferry hours during treatment, several new fuel and insecticide depots were created in the Sankarani, Mafou and Tinkiso basins.

ln the Eastem Zone, in addition to the experimental treatment of the Oti ^(weeks4 to 8), the Daka was also treated for

6

weeks due to poor entomological results on the Pru at Asubende. Some tributaries around Asubende (Pru), Titira (Keran) , Sikan (Kara), Bagan (Mo)and Pouda (Binah)were included among the biefs of rivers under aerial larviciding. Aerial larviciding was completely suspended during weeks 14, 15 and 16 due to good entomological results. As a precautionary measure to avoid BUG2000 and also because of very low water levels, aerial treatments were suspended during week 52.

Mr. R. Meyer, Chief

of

Aerial Operation in the East, departed

on

retirement

on

the

26nA99.

After the departure

of

R. Meyer, there was restructuring of Aerial Operations management as follows: Mr. A. Ake former Chief of Aerial Operations (WEST) was nominated as Aerial Operations Coordinator while Mr. A.

Diallo and Mr.

O.

Sina both former Assistant Aerops (West and East respectively), were nominated ^as Assistant to Aerial Operations Coordinator in Westem and Eastem Zones respectively.

1.2 Hydrology

ln the Programme area, the rains started in March and stopped in November. ln South of Guinea, Benin and Ghana higher precipitations were observed this year than in 1998. Consequently, rivers like Dion, Milo, Oueme, Mono and Pru had increased discharges. All other basins showed a similar discharge pattem as during the previous wet season, (Annex 1A,18).

Throughout the OCP a total of 56 satellite controlled beacons were used. They were :

26 pH 11 OCP 03Hydro Niger 23 pH11 OCP

4 FAC/Benin

West West East East

The major maintenance activities carried out during the year were

ln the West, 12 beacons were removed afterthe end of aerial treatment in the Bas Bandama, N'zi ^and Como6 basins. Also there was dismantlement

of

three beacons

on

the Sasandra river basin due ^to repeated theft

of

the Solar pannel ;reinstallation

of

beacons

at

Gueasso (10139

on the

Bogho) ^and Sansambaya (10168, Bale), and replacement

of

Hydroniger beacons with PH11

of

OCP

at

K6rouan6 (10141, Milo) Tinkisso (10201 on river Tinkisso), Mandiana ⁽¹⁰²⁰⁵on river Sankarani).

ln

the East, the beacon

atAnie

^(10173)was removed due to repeated theft. The stations at Naboulgou (10158) and Kpesside (1017a) were also removed because of very high water level. The station at ^Glei (10131

on

river Amou) was transfered

to

Zagnanado and

at

Naboulgou (10158, Keran)

and

Pouda (10162 on river Binah) the OTTX beacons were changed with Chloe C beacons.

Maintenance and repair of the beacons were conducted by four hydrological teams : two OCP teams and two national teams from Guinea, Collectively they carried out several hundred routine maintenance ^and repair missions. These included OCP assrstance

in

the repair

of

the Hydro-Niger and

the

FAC/Benin stations.

ln preparation for the experimental treatment on the Oti, water gauges at Mango, Porga, Borgou, Nagbeni and Naboulgou were read and checked and at Mandouri three gauge elements(0-1), (1-2) and ^(2-3)m were fixed.

Hydrological activities were canied

out

as well. There was no problem of shortage of spare parts.

1.3

^Treatment

Throughout the year a large number of suspensions of treatment were made due to good entomological results.

ln the Westem Zone, because of unsatisfactory entomological results on Mafou, Niger and Tinkisso river basins, some special actions such as an intensification of ground prospection, aerial treatment surpervision coupled with prospection, were canied out on these basins.

ln the Eastem Zone, due to the persistent ^poorentdmological results at Asubende on the Pru and Titira on the Keran during the wet season, aerial larviciding was extended to some tdbutaries of the Pru, Keran and Mo. Experimental aedal treatrnent was canied out on the Daka for 6 weeks (Bief 115). On some occasion combined heatment and prospection were organized.

1.4 AerialContract

1999 was the first year of the new EHI/OCP aerialcontract. A maximum fleet

of

5 aircrafts without spare

with

3001.6 guaranteed flight hours were allocated to the Programme. (See table 1 for repartition of fuC).

A total of 3019.2 hours were flown against the guaranteed hours, thus 17.6 hours representing 0.6 % in

excess. With the new contract, the guaranteed hours per aircraft is 53.8 as against 55.0 in the ^previous contract.

(4)

Evergreen pilots staff turnover was very high (see personnel movements EHI). From January to July 1999 three

line

pilots from West

and two

from East

left the

Programme. This sudden departure

left

no experienced Pilots in the West and only two in the East. To run aerial activities smoothly the rest of the year, EHI rehired three former experienced pilots after OCP drew the attention

of

EHI

on

this critical situation.

With the departure of J. Campbell and the two chief pilots (\{est and East), R. Gorman was nominated as the Project Manager based in Kara. J. Westrbook and D. Cotherman were nominated as Chief ^pilotsfor the West and East respectively.

The cooperation and communication between OCP and EHI staff and Management remained excellent.

The

aircrafts performed

well until

November

when

there

were

constant engine

and spray

system problems in the East. Radio communication was better this year than last year (See table ^6).

1.5.1 lnsecticide

Consumption

ln the Western Zone the consumption of all the ^productwas reduced compared

to

1998. This reduction could be explained by a better control

of

the chemical used. This year, more biological insecticide ^and etofenprox were sprayed

in

order

to

avoid resistance

of S.

damnosum larvae

to

organophosphates.

Consequently there was reduction ⁱⁿthe consumption of the other 5 products.

ln the Eastern Zone, the consumption of Etofenprox remained the same and Carbosulfan was used less compared

to

last year, while an increased consumption

of

all the other products were registered. ^The improvement of the susceptibility of the larvae to organophosphates, the good wet season, the extension

of

aerial larviciding

to

include some tributaries

of the

Pru, Keran and Mo and the experimental ^aerial treatment canied out on the Daka for

6

weeks (Bief 115), accounted for the increased use

of

these 5 products (Table 7 and 8).

The overall value of products consumed this year decreased by US$ 567522 (14.5%) as compared with last year.

1.5.2

Losses Refer to:

Overall losses due to theft, spillage and contamination decreased considerably compared to the ^previous year.

(5)

4

ln the Western Zone the biggest part of the loss concerned permethrin and etofenprox. ln Guinea theft of permethrin and etofenprox was carried out differently this year. lnstead of a whole drum being stolen, this time a quantity of 5 to 20 litres were taken from drums leaving the ^partiallyempty drums among the ^full ones. The Aerops team in Odienne have already taken some measures to combact the situation. ^The field depots inventory will be done if possible every three months in Guinea.

This year, the value of Losses were reduced by approximately 48% (94230US$), but an increased of ^the value of theft by 36% (13990 US$)was observed compared to 1998.

ln the Eastern Zone overall losses, due to theft, spillage/contamination and package remained high ^desprte the actions taken by Aerops and operational bases.

Iosses duc rn snillaoe/contaminari.^ .os,rlted from the ol.! stocks (temephos, carbosulfan, etofenprox ^and permithrin), poor package (phoxim).

Losses due to theft resulted

from

vandalism especially by empting the drum full of 8.t H-14 before taking these empty drums. Most of these misconduct took place at Badou, Titira and Aleheride in Togo.

ln 1999, the total value of Losses was increased by approximately 33.5% (18768.3US$), and reduction of the value of theft by 53.5% (8997.8 US$).

The overall losses throughout the OCP, amounted

to

5.3 %

of

the consumed product (Westem ^Zone 6.1%, Eastem Zone ^4.5%)

and

2.60/o

of

the total product handled (West 2.7%, East 2.4 %).

As noted last ^year,drums and/or seals of most of products (phoxim, permethrin, pyraclofos, etofenprox) are

of

poor and even decreasing

qualig.

Each year

a

considerable amount

of

product

is

lost due to spillage originating from leaking or rusted drums.
