The Revolutionary Government of Zanzibar (RGoZ) with the support of the World Bank has been developing the Open Data for Resilience Initiative (OpenDRI) with the aim of supporting evidence-based and innovative solutions to better plan, mitigate, and prepare for natural disasters.
Zanzibar is part of the Southwest Indian Ocean Risk Assessment and Financing Initiative (SWIO RAFI) which seeks to address high vulnerability of the Southwest Indian Ocean Island States to disaster losses from catastrophes such as cyclones, floods, earthquakes and tsunamis. These threats are exacerbated by the effects of climate change, a growing population and increased economic impacts.

Understanding Zanzibar’s Risk
Zanzibar’s disaster events are mainly related to rainfall, and both severe flooding and droughts have been experienced.

Data collected through SWIO RAFI activities will be shared on a GeoNode.
The ZanSea GeoNode currently contains 42 maps and 102 layers of geospatial data for Zanzibar.
The Zanzibar mapping initiative is creating a high resolution map of the islands of Zanzibar and Pemba, over 2300 square km, using low-cost drones instead of satellite images or manned planes. The Zanzibar Commission for Lands will use the maps for better planning, land tenure and environmental monitoring. Data is being collected in collaboration with the RGoZ.
Data collected can be used for risk assessment and planning activities.
