Development of an Inundation, Flooding and Landslide National Risk Profile, Maps,
Strategy Framework and Action Plans for Disaster Risk Management for the Republic
of Mauritius
1.
Background
To combat the climate change and its impacts and to reinforce its adaptation capacity, the
Government of the Republic of Mauritius (ROM) has signed a project agreement with the
United Nations Development Program (UNDP), for the implementation of a UNDP Africa
Adaptation Program (AAP) - Supporting Integrated and Comprehensive Approaches to
Climate Change Adaptation in Africa - The Republic of Mauritius (ROM). The Government
of Japan is funding the AAP.
The objective of the AAP is to develop a robust institutional framework for the
mainstreaming of climate change adaptation into core development policies, strategies and
plans of the ROM. The outputs of the AAP project are: (i) dynamic long-term planning
mechanisms to manage the inherent uncertainties of climate change introduced; (ii)
leadership capacities and institutional frameworks to manage climate change risks and
opportunities in an integrated manner at the local, regional and national levels strengthened;
(iii) climate-resilient policies and measures in priority sectors implemented; (iv) financing
options to meet national adaptation costs expanded at the local, national, sub-regional and
regional levels; (v) knowledge on adjusting national development processes to fully
incorporate climate change risks and opportunities generated and shared across all levels.
The ROM comprises the mainland Mauritius, small islands such as Rodrigues, St Brandon,
Agalega, and other outer islands. The mainland Mauritius is a small tropical island in the
Indian Ocean and is located near latitude 20o South and longitude 57o East. It has a total land
area of 2,040 km2, with a coastal zone mostly surrounded by fringing reef that encloses a
lagoonal area of 243 Km2. The topography of the coast comprises mostly of low lying areas,
flat plains in the north and minor cliffs in the western and southern part of the island, where
coral reef is absent. In 2010 its population was estimated at 1.3 million inhabitants.
Mauritius is swept by South East Trade Winds throughout the year, except for some short
periods in the summer months, when tropical depressions approach it. The country has been
affected by 23 Intense Tropical Cyclones located within 100 km radius of Mauritius, between
1960 and 2010 and also by occasional droughts, the most severe being those of 1998 and
1999. The impacts of climate variability and extreme weather events, inter alia, torrential
rains causing flash floods, landslides and water logging in low lying areas are becoming a
major concern. This situation is exacerbated by accelerated sea level rise which is likely to
provoke serious coastal inundation and erosion. On the other hand, climate variability may
also give rise to severe drought.
It is also anticipated that the climate-related hazards will aggravate the risks associated with
natural events in the future. Current evidence shows that climate change impacts will continue
to increase in frequency and severity.
Thus, the ROM proposes to develop an inundation, flooding and landslide risk profile, maps,
a strategy framework and action plans for the disaster risk management.

Consultancy
To implement the Disaster Risk Management component of the Africa Adaptation Program
(AAP), the services of an International Consulting Firm/ Consultants are required. Overseas
Consulting Firms/ consultants are encouraged to team up with local firms or counterparts and
,as far as possible, include local technical inputs.
The services to be provided include, the assessment and mapping of the vulnerable sites with
regards to flooding, inundation and landslides, and for the development of a national
framework for vulnerability assessment, the planning mechanisms, formulation of Disaster
Risk Reduction (DRR) policies, guidelines, adaptation strategies and action plans and
knowledge-base needs to respond to climate change related disasters in the years to come.
The main purpose of the assignment comprises, inter alia:
i.
ii.
iii.
iv.
v.
classification of climate change related risks;
analysis of these risks;
socio-economic analysis of the impacts related to flooding, inundation and landslide;
risk mapping and recommendations for the integration of risk management into urban
planning, development and governance; and
capacity building for disaster risk management.
3.
Objective
(a)
Overall Objectives
The global objective of this study is to develop an inundation, flooding and landslide national
risk profile, with maps, a strategic framework and action plans for the integration of disaster
risk management into urban planning and development, in the Republic of Mauritius. This
objective can be achieved through an in-depth analysis in relation to flood and inundation and
landslide hazards prevailing and anticipated and their associated risks and socio-economic
vulnerability.
(b)
Specific Objectives
The specific objectives of the study include:
i.
to prepare comprehensive maps, in appropriate scales of all flood, inundation and
landslide prone areas, based on historic data and information, and generate event
scenario simulations (sea level rise scenarios and flooding and inundation scenarios
associated with storm surges and flash floods);
ii.
to identify and assess the exposure of risks to people, property loss, critical facilities,
infrastructure, and economic activities as well as the potential losses (human,
economic and financial) related to flooding, inundation and landslide prone areas;
iii.
to identify and assess relevant elements at risk with reference to expected flood
magnitude;
iv.
to create national flooding , inundation and landslide risk profiles, supported by maps
of appropriate scale in terms of hazard and sector to identify priorities for National
Disaster Risk Reduction Strategies and Climate Change Adaptation Strategies;
v.
to carry out economic analysis of the impacts in relation to disasters and propose
adaptation measures;
vi.
to build capacity of stakeholders on disaster risk profiling, assessment and
management; and
vii.
to prepare a climate change investment program and action plans, with project briefs,
detailing project components, activities to be undertaken, objectives, implementation
time schedules, institutional arrangements and budgets, for disaster risk reduction and
management;
4.
Scope of the Consultancy Services
The scope of works shall include the mainland of Mauritius, Rodrigues, Agalega and St.
Brandon.
In respect of the above specific objectives, the Consulting Firm/ Consultants shall develop the
flooding, inundation and landslide hazard profiles and associated maps, using the application
of Geographic Information System (GIS) to support the following key tasks:
i. systematic description of the physical characteristics of flooding, inundation and
landslide hazards and of various descriptors, including sources of threats,
magnitude, duration, frequency, probability, extent and intensity field (spatial and
temporal distribution of intensity). Two kinds of flooding and inundation are to be
considered: ‘slow onset flooding and inundation’, as a result of sea-level rise; and
‘rapid onset flooding and inundation’, including occasional storm surges and flash
floods.
For the sake of comprehension, distinction has been made between the terms
‘flooding’ and ‘inundation’.
(a) Flooding is an overflowing of an expanse of water that submerges land. It is of
rapid onset as a result of heavy rainfall.
(b) Inundation has the same definition as flooding. However, in the present study,
inundation refers to coastal inundation caused by slow onset by sea level or rapid
onset caused by storm surges, cyclones or tsunamis.
ii.
development of hazard zoning maps, from updated cartographic/GIS data using high
resolution satellite imagery or Light Detection And Ranging (LIDAR), for temporary
flooding (1 meter contour interval) and for permanent inundation (0.5m interval up to
10 metres above mean sea level); and
iii.
development of: a) sea-level rise scenarios; b) flooding and inundation (inland
including coastal areas) scenarios caused by storm surges and flash floods, using GIS
applications;
Note: (1) All hazard and climate change scenarios shall be built for the predefined return
periods, i.e. 25, 50 and 100, years in order to compare the order of risks.
The Consulting Firm/ Consultants shall undertake an inventory of multi-sectoral exposures for
the following elements at risks for the ROM and their inclusion in the database of the
Geographical Information System:
-
population in terms of its poverty, gender and/or vulnerability;
-
buildings in terms of their structure type in vulnerable areas (wood-framed, concreteframed, steel-framed) and functionality (i.e. residential, commercial, industrial, and
public);
-
livelihoods, i.e. livestock, crops, industries (the number, location and extent of
exposure);
-
public facilities, i.e. healthcare (hospitals, clinics, basic health unit), educational
institutions (university, college, school), warehouses, stockpiles, banks, police
stations, fire stations, refugee centres; and
-
infrastructure, i.e. roads, bridges, airports, ports, hotels, ancient monuments, dams,
telecommunication network, power supply, water distribution system.
The Consulting Firm/Consultants shall develop a comprehensive national risk profile for
flooding, inundation and landslide, which reflects multi-sectoral concerns. A Risk
Aggregation and Coordination Unit shall be proposed for establishment and it will be the apex
administration unit. Other sectoral units of analysis could be also considered in terms of the
special requirements of other stakeholders.
They will identify national high-risk flooding, inundation and landslide areas associated with
sea-level rise, storm surges, flash-floods, heavy rain, and the sectors and relevant disaster risk
reduction and climate change adaptation options.
Several studies have been undertaken in the related fields in Mauritius, which the consultants
may consult. Some of them are:
A resource map of the coastal lagoons and reef areas of Mauritius produced by using
the CASI imagery (Ministry of Agro Industry and Fisheries) – 1996
Flood prone areas identified by the land drainage study of Mauritius (National
Development Unit) - 2001
Flood risks maps for some of the coastal wetlands (0.5 m, 1 m, 1.5 m and 2 m
elevations) in the Grand Baie Area, Mauritius, as part of the Study of Environmental
Risks in Grand Baie (Ministry of Environment & NDU) - 2002
Information on coastal erosion sites available from the Study on Coastal Erosion in
Mauritius (Ministry of Environment & NDU) – 2003

areas/hotspots, risk reduction measures, capacity of the risk takers to do risk management,
learning needs and tools.
Phase 4: Development of a Disaster Risk Reduction Strategic Framework and Action Plans
(1.5 months)
However, the firm/consultants may propose alternative phases that should be approved by the
contracting authorities.
This activity will comprise the development of a strategic framework on which will be
defined the different adaptation options to combat climate change impacts. In this framework
all the relevant laws, regulations and policies will be considered. Besides, it will also include
operational procedures for the management of the different disasters related to climate
change. This framework will be the platform for the development of contingency planning,
intervention procedures with all necessary regulatory mechanisms and access of information,
data and monitoring. Besides, a disaster risk reduction investment program will be prepared,
that will include, among others:
-
proposal for the setting up or reinforcement of the existing a climate data information
exchange system or observatory for easy access and use of these data, with the
relevant access policy and regulations;
-
adaptation options and their cost;
-
a DRR action plan with project briefs, cost estimates and implementation
arrangements.
The above-cited reports shall be reviewed by the Disaster Risk Reduction Technical
Committee and a national workshop shall be organized by the Consultants to discuss the key
findings and to validate the reports.
