DESCRIPTION
Presented by Dr Ousmane Ndiaye (ANACIM, Senegal). Africa Agriculture Science Week 6, 15 July 2013, Accra, GhanaTRANSCRIPT
Communica)ng downscaled, probabilis)c seasonal forecasts and evalua)ng their impact on farmers’ management of climate risks:
Examples from Kaffrine (Senegal) and Wote (Kenya)
Ousmane Ndiaye – ANACIM K.P.C. Rao – ICRISAT
Jim Hansen – CCAFS, IRI Arame Tall – CCAFS, ICRISAT
Hypothesis Since many farm management decisions are taken without knowing what the season going to be, advance informaHon about the possible seasonal condiHons will help farmers in making more informed decisions.

Key constraints addressed • Lack of awareness about seasonal climate forecasts and their reliability
• MispercepHons about the climate and its variability
• Lack of understanding about the probabilisHc nature of forecast informaHon
• Non-‐availability of informaHon in a format that can easily be understood by the farmers
• Dialogue between users and producers of climate informaHon

STEP 1: BUILDING AN INTEGRATED FRAMEWORK: THE MULTI-DISCIPLINARY WORKING GROUP
Seasonal forecast ⇒ varie)es Onset forecast ⇒ farm prepara)on
Nowcas)ng ⇒ flooding saving life (thunder) Daily forecast ⇒ use of fer)lizer / pes)cide Decade forecast ⇒ weeding, field work
Evalua)on Lessons drawn
Training workshop Indigenous knowledge Discussion and mee)ngs
Field Visits experts mee)ng each 10 days : monitoring the season
Decade forecast ⇒ op)mum harves)ng period Daily forecast ⇒ saving crops leS outside
Before During the Crop season Maturity/end
Methods used in Kaffrine (West Africa) and Wote (East Africa)
• The study was conducted in Kaffrine disctrict (Senegal) and Wote division, Makueni district, Eastern province (Kenya) during the 2011 & 2012 rainy seasons
• Study treatments include – Survey (Control) – InterpreHng and presenHng seasonal forecast informaHon in the form of an agro-‐advisory
– Training workshop along with advisory – EvaluaHon
Building on local knowledge: High humidity and high temperatures can explain some of their indicators è “Stronger monsoon” Doing quite the same thing BUT Be\er 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
STEP 2: BUILDING TRUST LINKAGE TO INDIGENEOUS KNOWLEDGE
team work : farmers, climatologist, World Vision, Agriculture expert, sociologist

Ø First step : building trust (social dimension : using indigeneous knowledge)
Ø Giving not only useful BUT useable forecast (tailored for specific user needs)
Ø Long term and mulH-‐stakeholders partnership (each insHtuHon has part of the soluHon for food security)
Ø CommunicaHng probabilisHc aspect of the forecast (easy to understand, can translate into acHon and to evaluate)
Ø Dynamic process : need to be\er understand farmers decision system (long term dynamical partnership)
Ø The forecast covers a large area : we need forecast at farm level Ø Farmers sHll lack of tools and materials beside climate informaHon
LESSONS AND CHALLENGES
Ø « We were guessing now we have decision tools » Ø « The early warning system of an very early rainfall saved all my crops lea outsides»
Ø « with eminent rainfall forecast through sms (nowcasHng) we can saveguard our ca\le, return from farms to avoid thunder »
Ø « we woman (soeur unies de Ngodiba) are now be\er of and as equipped as men now. »

Methods • In Kaffrine: 300 farmers trained, more than 1000s received climate services (33% of women)
• In Wote: A total of 117 farmers (61% women) accessed and used climate agro-‐advisories
• Farmer use of climate informaHon was assessed by conducHng three surveys – Before training or providing forecast informaHon – During the season – Aaer the season
