CLIMATE CHANGE AND IMPACTS: KEY MESSAGES FOR AFRICA
Africa’s climate is already changing and the impacts are already being felt
1
Further climatechange is inevitable in the coming decades
2
Climate change poses challenges to growth and development in Africa
3
Adaptation will bring immediate benefits and reduce the impacts CC
Adaptation isfundamentally aboutrisk management
Adaptation experiencein Africa is growing
Some low-carbon dev.options may be less costly In the long run and could offer new economic opportunities
Africa stands to benefit from integrated climateadaptation, mitigation and development approaches
International cooperation is vital to avert dangerous climate change and African governments can promote ambitious global action

CHALLENGE
• Bring smart and affordable ICT to everyday farm management for smallholders – to help boost sustainable agricultural production in Africa.

Smart Information and Communications Technology (ICT) for Weather, Water Information, EWS and Advice to Smallholders in Africa

• Satellite images are increasingly being used to assist commercial farmers and agribusinesses
• Innovative approaches and ICT based technologies• Advice to end users for:
• informed decision making• enhanced negotiation capacity with water and farm related service
providers
WHAT ARE THE OPPORTUNITIES TO USE ICT TO INCREASE AGRICULTURAL PRODUCTIVITY?
• IWMI has developed, test and pilot cell-phone and web-based information systems to provide near real time climate, vegetation, and water information relevant to the agricultural value chains
• To assist farmers, irrigation boards, agriculture extensions and water user associations by providing the information needed to make better management decisions

THE CONCEPT
• Develop online data base for all registered arm fields in Projects sites, around 60 fields in each site
• Use high-resolution RS data to monitor the condition of crops in a farmer’s field
• Convert this info into simple regular agro-advisory delivered to farmers through SMS
• This should help optimise farm profits by providing water and other inputs at the right place, time and quantity

DATA PRODUCTION
Raw DMC satellite data for 21-11-2012 (L), and derived daily evapotranspiration (M) and biomass production (R).
• ET, Biomass Production and related parameters are calculated spatially discrete for all three project areas, based on high-resolution images
• Instantaneous data (valid for the moment of satellite image capturing) are converted to weekly products for the pre-defined seasons
• This procedure is repeated every week: keeping track of the varying crop water conditions throughout the season

OUTPUTS – FLOODING MONITORING
• Only for Sudan; Two flood seasons to date – 2012 and 2013
• Disaster management angle – will Kassala town be affected?
• Water use efficiency angle – do farmers use diverted water for spate irrigation?
Gash Delta, Sudan

OUTPUTS - WEB PORTAL, AND SMS SERVICE
• FieldLook portal www.fieldlook.com - in English, Arabic and Oromiffaa
• Fieldlook spatial data are “translated” into simple SMSs - both qualitative and quantitative, and both on-demand and weekly “push”
• SMS services match desired information, farmer skills, and language, and consistently revised according to user feedback

The crop has no water stress when the soil moisture is above the critical
level and below the field capacity
OUTPUTS - IRRIGATION ADVICE
When the soil moisture drops
below the critical line, irrigation is
advised
