MOTIVATIONS

Short rainy season : 4 months

Strong climate variability (strongest in the world and at all time scales)

Huge socio-economical impacts :

Health : malaria, meningitis

Agriculture : (90% in Senegal) rain fed and pastoralism

limited economic resources

Sahel

GHCN Series: 12-20N, 18W-30E

Problems of true versus false onset

Same period of onset but followed by dry spell which affect any planning

False Start True Start

Building on local knowledge:

High humidity and high temperatures can explain some of

their indicators “Stronger monsoon”

Doing quite the same thing BUT

Better observing system

More reliable storage capacity (numbers, maps, computers,

…)

« When the wind change direction to fetch the

rain » = Wind change from harmatan to monsoon

during onset

• Selecting the crop :

• Planting :

• Weeding :

• Applying fertilizer,

pesticide, …

• Harvesting :

First step : building trust (social dimension : using indigeneous

knowledge)

Giving not only useful BUT useable forecast

(tailored for specific user needs : local language)

Long term and multi-stakeholders partnership (each

institution has part of the solution for food security)

Communicating the forecast in easy to use term

(easy to understand, can translate into action and to be evaluated)

Dynamic process : need to better understand

farmers decision system (farmers active participation : rain guage,

indigenous knowledge …)

WHAT DID WE LEARN

Page 17: Institutional partnerships to tailor downscaled seasonal weather forecast for the end-users

CONCLUSION OR CHALLENGES Spatial scale of the forecast : down to farm

Up-scaling other sites (government representative demand)

Alternative :

dry (bad news !) =>give them hope (climate insurance, alternative)

wet but there is no extra resources : so what ? (engage

seed/fertilizer producers, bank (CMS), corporation, … )

High rate of adoption by farmers and local administration

(official )

SOLUTION : whole package with other partners (WFP)

① Climate services (forecast + technology => advices)

② Climate insurance (dry/bad forecast + courage)

③ Access to finance, resources (wet//good forecast)

PRELIMINARY VERIFICATION 2012

(by farmers and extensions)

Extra seasonal rainfall :

Early warning issued on the May 16th for rain on the next 8 days

It did rain on the 21st May 2012 (save a lot on crop left outside)

True Onset :

Forecast made on 9/10 May updated 10 June : 18 to 24 June 2012

First significant rainfall : 19 June (all kaffrine) (03Jun)

Seasonal forecast :

Forecast (9-10 May) : Normal to below normal (500 – 900 mm)

Recorded rain in kaffrine : 576-1075 mm (Normal to above normal)

Early Warning System : ( 10 day, 1-2 day, 30mm to 3 hour)

21 forecasts (all time scales) only 4 went way off

problem of spatial coverage of the forecast kaffrine is too wide !
