slide6

Droughts vs. Food Security

  • Most complex of all natural disasters; Slow-onset
  • No general definition of drought
  • No physically measurable variable
  • Two different fields of research (no “IPCC” for food security)
  • Large gap between scientific findings and decision-making
  • Satellite technologies (soil moisture)far from complete exploitation
slide8

SATIDA

(Satellite Technologies for Improved Drought Risk Assessment)

In a nutshell:

  • 18 months; Funded by Austria Research Promotion Agency
  • Collaboration of researchers from different disciplines
  • Main objective: Test and visualize the added-value of satellite-derived datasets and seasonal forecasts
  • Link drought risk to socio-economic vulnerability via mobile applications (smart phones, tablets)
  • www.satida.net

slide13

The Role of Mobile Applications

  • Access to monitoring and forecasting datasets
  • Collection of socio-economic information
  • Full exploitation of smart phone features
  • Questions focus on level of malnutrition, food basket, access to resources, etc.
  • Field test in Ethiopia and the Central African Republic with Doctors without Borders in 2015

Conclusion (I)

  • Simple data access and clear visualization are vital
  • Added-value: Increased lead time for logistics, HR, pro-active operational planning
  • Decision-makers need information about environmental AND socio-economic conditions
  • Mobile apps help to relate index-outputs to conditions on the ground (validation)
  • Smart phones create a feeling of ownership

slide19

Conclusion (II)

  • Mobile applications need a robust back-end
  • They must as well work online/offline
  • EO can be powerful when capacities and limitations are identified and explained to the user (non-generic approach)
  • Solutions need to be developed with, not for users
  • Approaches like the EODC are promising, if they manage to create a network
