CLIMATE CHANGE AND IMPACTS: KEY MESSAGES FOR AFRICA
Africa’s climate is already
changing and the impacts
are already being felt
1
Further climate
change 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 is
fundamentally about
risk management
Adaptation experience
in 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 climate
adaptation, 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
Biomass production for 21-27 March,
2013 at the field of the maize farmer
Ibrahem Abdel-Halim Hasanen, Egypt

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
