Launching next generation ICT for weather and water information and advice to smallholders in Africa

  1. 1. www.iwmi.org Water for a food-secure world Launching Next Generation ICT for Weather and Water Information and Advice to Smallholders in Africa Bharat R Sharma, L. Rebelo, G. Amarnath, I. Miltenburg 5th CRS ICT4D Conference: Mobile Services that Empower Vulnerable Communities March 19-21, 2013; Alisa Hotel, Accra, Ghana
  2. 2. 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.
  3. 3. Water for a food-secure worldWater for a food-secure world 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
  4. 4. 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 delivery infrastructure • Develop user applications Run Operational Service • Data acquisition (satellite imagery) • Calculation automation • Tool application • Development of Information Package • Central storage • Dissemination through user application
  5. 5. Water for a food-secure worldWater for a food-secure world Topic Contribution Ethiopia (Arata Chufa) Sudan (Gash region) Mali (Office du Niger) Egypt (Naubariya Governorat e) Weather Temperature , rainfall, RH, wind speed, reference ET y y y Hydrology River flow y Crop growth Biomass production, yield, Nitrogen, Leaf Area Index y y y y Agricultural Water Manage. Crop water stress, crop water use, water productivity, soil moisture, irrigation advise y y y y Flood Inundation extent Daily/weekly spatial surface water extent for Gash delta/mesga blocks; flood early warning Y 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.

  7. 7. Smart ICT for Weather and Water Information and Advice to Smallholders in Africa 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
  8. 8. Smart ICT for Weather and Water Information and Advice to Smallholders in Africa 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) Example FieldLook Web Platform  Information packages ((2)weekly/seasonal)  Based on satellite imagery
  9. 9. 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 http://earthobservatory.nasa.gov/NaturalHazards/vie w.php?id=12099 Spatially distributed data is assimilated to simulate stream flow on a daily basis

  12. 12. Water for a food-secure worldWater for a food-secure world 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.
  13. 13. Water for a food-secure worldWater for a food-secure world 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
