About Taiwo Ogunwumi

Taiwo Ogunwumi is a specialist advisor in Flood Risk and Disaster Management, with deep expertise in applying geospatial science and technology to reduce vulnerability and enhance resilience in flood-affected and high-risk regions. He integrates advanced flood modeling, GIS-based hazard mapping, and post-disaster assessments to turn complex data into actionable insights that drive more effective preparedness, response, and recovery strategies.

At Deltares, Taiwo contributes to flood risk management and impact assessments across Africa, Asia and Europe, leveraging software and tools. His portfolio includes projects in the Netherlands, Nigeria, Ghana, South Sudan, São Tomé and Príncipe, Madagascar, India, Malaysia, Pakistan, and Ethiopia—supporting governments, humanitarian agencies (UN and INGO), and international partners in building adaptive, data-driven resilience solutions.

Beyond technical work, Taiwo is passionate about capacity building and community engagement. He leads training that equip local stakeholders, emergency responders, and development partners with cutting-edge tools for flood early warning, flood preparedness, recovery, risk analysis, and climate adaptation—bridging the gap between science, policy, and grassroots action.

Project revolves around the following themes:

• Flood Risk & Vulnerability Assessment
• Disaster Risk Preparedness & Recovery
• Geospatial Decision Support System
• Climate Adaptation in Refugee Settings
• Training and Capacity Development

Taiwo’s notable contribution include:

At Deltares, in collaboration with the International Organization for Migration (IOM) and UNHCR, Taiwo Ogunwumi led a flood risk management of IDP camps in conflict-affected regions of Nigeria. His work contributed to critical flood risk mitigation strategies and life-saving preparedness plans for displaced communities.

He has also played a key role in international flood resilience projects including:

• Compound flood hazard mapping in São Tomé and Príncipe & Madagascar
• Development of a multi-hazard forecasting platform for climate extremes in Iskandar, Malaysia.
• Flood risk assessments for refugee camps in Ethiopia and South Sudan & Nigeria

These projects have informed national adaptation strategies and guided donor-supported resilience planning in highly vulnerable regions.

Additionally, Taiwo has led specialized training sessions for organizations such as United -IOM and Makerere University. His workshops—focused on tools like flood impact modeling, flood preparedness & recovery —have significantly enhanced the technical capacity of institutions across East and West Africa to manage water-related disasters more effectively.
