Previously, he was a Professor of Geography at King's. Before this, he was based at the departments of Geography at University of Liverpool and University of Guyana. He has served as a coordinating lead author for the Intergovernmental Panel on Climate Change Sixth Assessment Report and Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) and as lead author on its Fifth Assessment Report. He is a member of the Scientific Steering Committee of the Stockholm Environment Institute and the Development Team for the Future Earth Risk Knowledge Action Network. He chairs the Centre for Integrated Research on Risk and Resilience, and is currently seconded for half his time to the United Kingdom Research and Innovation (UKRI) Global Challenges Research Fund as a Resilience Challenge Lead.
He is working in the Department of Earth Systems Analysis, and contributes to the research theme 4D-Earth, specifically to Natural Hazards and Disaster Risk Management. He was involved in projects related to the development of open-source GIS software and developed many training materials on the use of GIS for hazard and risk assessment. From 2005- 2015 he was Director of the United Nations University - ITC Centre on Geoinformation for Disaster Risk Management. He has carried out research on different hazard and risk related aspects: landslide hazard and risk (e.g. Austria, Switzerland, Italy, Romania, India, China, Vietnam, Colombia, Central America, Caribbean), volcanic hazard and risk assessment (Colombia, Philippines, Central America, South America) and technological risk assessment (India). He worked on national scale risk assessment projects in Central America, the Caribbean, Caucasus, and Central Asia. His current research interest is to develop methods for the analysis of changing multi-hazard risk.
He serves on the Harvard Medical Faculty Physicians Division of Disaster Medicine in Cambridge, Massachusetts, and Eastern Washington University. He has over 24 years of experience in fire service management, EMS, special operations, CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) response, disaster preparedness, and disaster management. He has served as Deputy Chief of Emergency Services in Salem, Oregon, and is a member of Oregon’s State Regional Hospital Preparedness Group, Public Health, and Incident Management Teams.
His expertise lies in Geographic Information System conception and implementation, digital topography, GPS surveys, and digital cartography. Rebai has led projects such as the water point data digitization for the DGRE project and topographic studies covering vast areas. He has contributed significantly to research, particularly in geodynamic studies using GPS and terrain modelling techniques. Rebai’s professional experience spans various roles, including GIS project management, training in computer science at the University of Villetaneuse, and geodetic work at the National Geodesy and Leveling Service in Tunisia.
Natural disasters are on the rise globally, causing more destruction than ever. The total
number of disasters has nearly doubled worldwide since the 1980s, while in Africa, the
incidence of natural disasters has almost tripled during the same timeframe. The complex
interplay between natural disasters, rapid urbanization, water scarcity, and climate change
presents a significant challenge for policy and planning. According to projections by
climatologists and United Nations experts, African economies and livelihoods are expected
to be the second most affected by climate change. In response, governments across the
continent are increasingly seeking comprehensive services for natural hazard and crisis
management. Since 2007, Morocco and a range of country-level programs have been
launched in Djibouti, Tunisia Algeria, and in the Republic of Yemen in the Middle East to
enhance resilience and recovery efforts. This congress assesses progress in risk
management in Africa, identifies intervention gaps, and expands the dialogue towards
more proactive, collaborative risk management. It will provide a collaborative platform to
develop a strategic vision, principles, and objectives for Disaster Risk Reduction and
Management.
Recent years have seen significant changes in global risk management policy due to the
increasing frequency and severity of catastrophic events. These changes have prompted
broad reforms affecting institutional frameworks and public policy initiatives.
In 2023, Africa was struck by a series of catastrophic natural disasters. The most
devastating of these occurred in Libya, where unprecedented floods ravaged Derna,
destroying a quarter of the city’s neighborhoods and claiming over 11,000 lives. North
Africa endured raging wildfires amid a scorching heatwave, with temperatures approaching
50 degrees Celsius in some areas. Cyclone Freddy hit Mozambique with winds of up to
110 mph, leading to floods that caused 1,434 deaths. This event marked Freddy as the
deadliest tropical cyclone on record in Africa. In addition, severe flooding in the Democratic
Republic of Congo and Rwanda resulted in at least 574 fatalities and displaced thousands.
Morocco has faced different types of natural disasters over time, including earthquakes,
droughts, floods, and cold waves. Notably, on September 8, 2023, an earthquake of 6.8
magnitude struck the High Atlas Mountains. Known as the Al Haouz earthquake, it
originated approximately 75 km southwest of Marrakesh and significantly impacted the
region bearing the same name. Regrettably, the Al Haouz earthquake ranks among the
most catastrophic disasters in Morocco’s recent history, resulting in an estimated 3,000
deaths and 5,500 injuries in the subsequent weeks. Moreover, the Kingdom of Morocco
continues to confront challenges due to its history of disasters, highlighting the urgent
need for comprehensive disaster planning and mitigation measures. Consequently, under
the guidance of His Majesty King Mohammed VI, May God Grant Him Assistance, the
groundwork has been established for the nationwide approach to risk management of
natural calamities (2020–2030). This strategy represents a consensus among various
stakeholders and marks the beginning of an inclusive process that involves reflection,
analysis, and collaboration.
The term"risk management" implies processes of prediction, prevention, control and
reduction of the risk factors. It involves developing, promoting, and implementing policies,
tools, and actions that assist societies in minimizing their exposure to natural risks and
reducing their vulnerabilities. The risk concept should not be solely hazard-focused from a
naturalistic perspective; it must also consider the social construction of risks, which
depends on societal structures, organization, and functions. Consequently, this congress
seeks to foster collaborative efforts among scientists, practitioners, NGOs, and politicians
from the African continent, in partnership with international allies, to enact risk
management policies. Collaboration among national and international institutions and non-
governmental organizations (NGOs) is essential. The aim is to establish a global dialogue
forum to forge consensus among various stakeholders on objectives and actions such as
protocols, treaties and conventions.
The 1st African Congress on Natural Risks and Disaster Management (AFRICA
NRDM'2025) will be held from January 20th to 24th, 2025, in Rabat, the capital city of
the Kingdom of Morocco. The event will be organized in collaboration with the Academic
Platform, The African Organization for Studies and Research on Risks, and the
Mohammed V University of Rabat, with the support of the Risk Management Directorate
under the Ministry of Interior.
The NRDM’2025 congress is an opportunity to intensify efforts and strengthen the
partnership with various international and governmental organizations, non-governmental
organizations, civil society actors, academic institutes and African universities to develop
an effective and comprehensive disaster risk management strategy in African countries.
The objective is also to promote the pivotal role of civil society organizations in creating
networks and focal points for disaster risk reduction at the African level.
In this regard, this meeting aims to highlight the role of the heads of municipalities,
territorial authorities and mayors of African cities due to their involvement in public
administration.
In addition to enhancing the involvement of civil society actors focused on risk
management in Africa, it is essential to integrate disaster reduction by adopting specific
policies within local, national, and regional planning processes that consider the
contributions of all stakeholders.
