Water for a food-secure worldWater for a food-secure world
Water is an increasingly scarce input in
agriculture in Africa.
•The challenge is to increase agricultural
production while reducing water
consumption.
Smart and affordable technologies need to be
adapted to customize farm management for
smallholders.
•Tools that can monitor plot specific
information and generate advice shall be
helpful.

What are the opportunities to use ICT to increase
agricultural productivity?
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

Smart ICT for Weather and Water
Information and Advice to
Smallholders in Africa
What did we already do?
Development Tools
& Algorithms
• Develop Tool
algorithms ->Turn
satellite imagery
and ancillary data
into valuable
information
• Develop
operational
calculation system
• Develop data

infrastructure
• Develop user
applications
Run Operational
Service
• Data acquisition
(satellite

Strategy and Approach: Modular
Information packages and transfer modes (cell phone, radio, smart
phone, web) will be piloted based on the requirements and
possibilities per location.

From pixels….to information….to simple action messages
Foreachfield:weekly
predictions:

Development of Information Packages
• Weekly calculation of information package from satellite image
• Period: 2012: August 15 – December 31 -> Finished and available
• Period: 2013: August 15 – December 31 -> Next season
• 9 parameters (evapotranspiration, biomass growth, crop stress, …)
14-Dec – 20-Dec 2012
Biomass Production
[kg/ha/week]
High detail:
20m spatial resolution
0 400 800

Example Operational service
• Minerals
• Growth
• Moisture
• biomass production (kg/ha)
• leaf area index LAI (m2 leaf/m2 ground)
• vegetation index NDVI
• evaporation shortage (mm/week)
• current evaporation (mm/week)
• surplus rain (mm/2 weeks)
• reference evaporation
• Nitrogen content in the top leaf layer (kg/ha)
• Nitrogen content in all leafs (kg/ha)

 Based on satellite imagery

Water for a food-secure world
• Frequent rain-induced floods result in heavy losses in agriculture in this region
The GeoSFM is a semi-
distributed physically
based hydrological
model that simulates the
dynamics of runoff
processes using RS data
Inundation and flood forecasting: The Gash River, Sudan

Spatially distributed data is assimilated to simulate stream
flow on a daily basis

Final Outputs
• Cell-phone and web-based information system
developed and tested in pilot areas.
• Different stakeholders/ end users are able to
make use of information and advice for better
management, negotiation.
• Priorities for specific weather, water, crop
related information agreed and mode of
transfer identified.
• Agri-industry and other service providers
interested in expansion and continuance.

Target Groups
• Individual smallholder farmers
• Contract farm managers
• Water User Associations
• Irrigation Boards and Block Inspectors
• Agriculture Extension Service Providers
• Crop and Livestock Insurance Companies
• Commodity stock cooperatives/ traders
• State Dept. of agriculture/ irrigation/Meteo.
• Agric. Research Institutions
