The document describes the SATIDA project which aims to (1) develop a platform to analyze satellite data and link it to socioeconomic assessments to monitor drought risk, (2) test this with Doctors Without Borders in Central African Republic and Ethiopia, and (3) create a mobile app for field data collection. It outlines SATIDA's objectives, method of combining precipitation, soil moisture, temperature and vegetation indices to calculate an enhanced drought index, and demonstrates the platform and app for analyzing current and forecasted drought conditions and impacts.

4. SATIDA Objectives
→ Develop platform to ingest, analyze and visualize
various satellite data
→ Link satellite-derived info about current and
future drought risk to assessments of socio-
economic conditions
→ Collaboration directly with Doctors without
Borders (MSF)
→ Test the added-value

• Enables access to
information about current
and future drought risk in
vulnerable regions
• Helps to collect additional
socio-economic
information on household,
