DESCRIPTION
Presentation by O Ndiaye, at the CCAFS Workshop on Institutions and Policies to Scale out Climate Smart Agriculture held between 2-5 December 2013, in Colombo, Sri LankaTRANSCRIPT

Institutions and Policies for Scaling Out Climate Smart Agriculture “, 2-3 December 2013 Colombo, Sri Lanka

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

BUILDING A TEAM OF STAKEHOLDERS :
MULTI-DISCIPLINARY APPROACH. National Level :
National Weather Service (ANACIM)
Ministry of agriculture (DA)
Initiative Prospective Agriculture and Rural (IPAR)
Ecological Monitoring Center (CSE)
national agricultural research institute (ISRA)
National department of water resource management (DGPRE)
ENDA Energie
Local extension services and NGO in Kaffrine :
agricultural advisers and extension (ANCAR)
Service Départemental du développement Rural (SDDR),
NGO : Volunteers from Red Cross (CR), Africare (PRODIAK), World Vision (WV),
Farmers organizations :
National Farmers (Japandoo, CNCR, FONGS, … ), Individual farmers,
Organization of women producers (GPF), Peanuts-Seed producers Cooperation (CPSA)
Communication :
community and rural radio,
National TV, Private radios and TVs (Sud FM, Wal Fadjri, )

Multi modeling approaches
STATISTICAL

PREDICTION :

Problems of true versus false onset
Same period of onset but followed by dry spell which affect any planning

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

• Field preparation :
• Selecting the crop :
• Planting :
• Weeding :
• Applying fertilizer,
pesticide, …
• Harvesting :
• Storage :

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

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 !
