Understanding Niger’s Risks
Despite its semi-arid climate, Niger is regularly stricken by floods that destroy housing, infrastructure and croplands everywhere in the country. While flood damages usually occur in the vicinity of permanent water bodies such as the Niger and Komadougou rivers, more and more damages and casualties have been reported as linked to intense precipitations and runoff in urban areas. Despite the recurrent losses, little is known about the number of people who are living in flood-prone areas or the value of properties at risk. Furthermore, the vast majority of stations in the meteorological and hydrological collection network does not have the ability to transmit data in real-time and therefore cannot be fully exploited in emergency situations.
With the support of the World Bank, the PGRC-DU is supporting the Nigerien Ministry of water and sanitation to retrofit the hydrometric station network with new water level gauges with real-time data transmission capability. The new gauges will make hydrometric data collection more efficient and more reliable while allowing for a faster detection of flood risk. At the same time, the PGRC-DU is funding the collection of critical socio-economic information and building characteristics in all areas of Niamey (the capital of Niger) that are deemed vulnerable to floods. UAVs are being used to acquire high-resolution images of potentially flooded areas that would help better identify buildings characteristics and develop a Digital Terrain Model (DTM) with 10cm vertical resolution, which will help better predict water movement in the area.
The collected hydrometric data will be available to selected users in an online portal, along with various other data sets from regional and global sources. Part of the data collected in Niamey is expected to contribute to the OpenStreetMap project. The rest of the data will be analyzed and converted into vulnerability maps and reports available to the public.
It is expected that the network of real-time hydrometric stations will be used to feed a flood warning system that will provide authorities a better estimate of flood risk at any given time. The acquired DTM is being used to develop computer models that can simulate flood propagation in the city of Niamey and evaluate the effects of existing of planned flood protection infrastructures. Finally, the collected socio-economic data combined with flood simulations will provide decision-makers an accurate estimation of flood risk in terms of exposed populations and expected economic damages.
In Uganda, the World Bank is supporting the Government to develop improved access to drought risk related information and quicken the decision of scaling up disaster risk financing (DRF) mechanisms
National Emergency Coordination and Operations Center (NECOC)
In the context of the third Northern Uganda Social Action Fund Project (NUSAF III), the World Bank is supporting the Government of Uganda to develop improved access to drought risk related information and quicken the decision of scaling up disaster risk financing (DRF) mechanisms. The OpenDRI team is providing technical assistance to Uganda’s National Emergency Coordination and Operations Center (NECOC) in determining requirements for collecting, storing and analyzing satellite data used for monitoring drought conditions.
Understanding Uganda’s Risk
In recent years Uganda has been impacted by drought, with more than 10% of the population being at risk. The northern sub-region of Karamoja is one of the most severely hit, with a consequent increase in food insecurity. Currently the Government of Uganda (GoU) faces challenges in the collection and analysis of information upon which they can base a decision to respond and mitigate such risk. Without transparent, objective and timely data, times in mobilizing and financing responses can be delayed.
The World Bank is supporting GoU to strengthen its disaster risk management strategy and response mechanisms. The current engagement looks to develop a more systematic, robust system for collecting, storing and analyzing drought risk related information to enable GoU to make more timely decisions. By retrieving satellite data systematically, NECOC will be able to analyze current crop and vegetation conditions with historic information, and quickly detect early warning signs of drought.
Uganda has a vibrant OpenStreetMap community, which has been mapping the country since 2010. A pilot community mapping project funded by GFDRR with support from the Government of Belgium, is being conducted in the city of Kampala.
The OpenDRI team provides support and advice to GoU in developing best practices for sharing and managing risk related information. Interoperability of data sources produced by various ministries and non-government organizations is critical to ensure timely access to data by NECOC and conduct effective drought risk analysis. A geospatial data sharing platform will be deployed by GoU to facilitate exchange of such critical information and adoption of data standards.
A technical committee, composed of experts from the government and partner organizations, has agreed to use a satellite derived indicator known as Normalized Difference Vegetation Index (NDVI) as the primary dataset to inform decisions for triggering the disaster risk financing mechanism. Initially the system will be exclusively dedicated to monitoring drought risk in the northern sub-region of Karamoja. In the following years, it is expected to expand operations and cover other regions exposed to drought risk, integrating additional data sources which will become accessible thanks to improved data collection strategies and sharing mechanisms.
The Revolutionary Government of Zanzibar (RGoZ) with the support of the World Bank has been developing 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.
Island Map: OpenStreetMap
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.
The Disaster Management Centre of Sri Lanka (DMC) with the support of the World Bank has been developing the Open Data for Resilience Initiative (OpenDRI) to support evidence-based methods to better plan for, mitigate, and respond to natural disasters.

Understanding Sri Lanka’s Risks
Since 2000, flood and drought events have cumulatively affected more than 13 million people across Sri Lanka. Regular flooding, drought, and landslides are natural hazards that threaten the long-term growth and development of the country. In Sri Lanka, nearly $500 million in unplanned expenditures resulting from flooding in 2010 and 2011 has strained government budgets and required reallocation from other planned development priorities. The impacts of these events are growing due to increased development and climate change, both of which put more assets at risk.
To enable better disaster risk modeling, the Government of Sri Lanka partnered with GFDRR, UNDP and OCHA on the development of an OpenDRI program in November 2012. This branch of the initiative focused on the South Asia Region and was dubbed the Open Cities project. A component of the OpenDRI Open Cities mission in Sri Lanka was to collate data around hazards and exposure and prepare them to be uploaded into a GeoNode which serves as a disaster risk information platform.
Working with the DMC, the National Survey Department, Department of the Census and Statistics, Nation Building Research Organization, Information and Communication Technology Agency, Department of Irrigation, several universities and the international partners, the OpenDRI team supported DMC with the aggregation of data that had been stored in static PDFs, old paper maps and several databases onto the GeoNode.
The data on the GeoNode is currently available to authorized users in the OpenDRI network, in preparation for launch. This transitional state is typical for open data projects, as the partnership reviews data with the parties and affirms that it is ready for release to the open public. Some layers may restrict access only to authorized users.
The project has also built technical capacity and awareness in Sri Lanka through training sessions on open data and crowdsourced mapping in Batticaloa city and Gampaha District. As a result of the Open Data for Resilience Initiative, government and academic volunteers have mapped over 130,000 buildings and 1000 kilometers of roadways on the crowdsourced OpenStreetMap database. This enables the country to plan ahead and be prepared for future disaster and climate risks. It also helps planning during disaster responses: the data was used to assess flooding impacts in real time and direct government resources during the May 2016 floods in Gampaha district.
