1.2 Statement of Problem
Incidents of flood are not
a recent phenomenon to people of Makurdi as they have been living in
flood prone areas for centuries. Like most urban areas of the third
world, Makurdi has experienced accelerated population growth which has
led to changes in the land use activities. Land use changes in
particular, have a direct impact on the magnitude and behavior of floods
(Civco et al 2002). Flash floods are common features in Nigeria during
the rainy season(May-October) but the country’s flood event of the year
2012 have been described as the most devastating in over 40 years.
Two
major events took place between the months of September and October
2012 in Nigeria, namely the Ladgo Dam flood in Adamawa State, and the
River Benue and Niger adjoining States floods (Niger and Benue States).
The event pushed most of the country’s rivers over their banks and
submerged hundreds of kilometers of urban and rural land. This resulted
in widespread devastating flood disaster that hit the country cutting
across major cities in about 14 states that borders the Niger-Benue
River. The flood submerged houses and several transportation routes
throughout the affected areas nationwide. Overall, an estimated 1.3
million people were displaced and about 431 people lost their lives with
several hectares of farmland destroyed (MISNA, 2012). Though the
unusually large flood was predicted by the Nigeria Metrological Agency
NIMET, government at all tiers failed to act on time, resulting in the
worst humanitarian crises in Nigeria since the civil war in 1967-1970.
Despite
the expected increase in frequency and magnitude of flood in the
Nigeria and invariably Makurdi, few impact assessment studies on the
socio-economic livelihood of the people have been undertaken to
establish the underlying causes of their vulnerability. In the absence
of comprehensive data and information, the measures to cope with flood
have remained ad hoc.
Objective of the study
The main objective of
this study is to examine the effect of flood on roads durability in
Nigeria. Specifically, the study aims to:
Ascertain the causes of flood in Nigeria
Examine the socio-economic effect of flood in Nigeria
Examine the effect of poor drainage on flood incidents in Nigeria
To ascertain if flood affects road durability in Nigeria
Research Question
What are the causes of flood in Nigeria ?
What is the socio-economic consequences of flood in Nigeria?
Does poor drainage system the reason for flood incident in Nigeria?
Does flood affect road durability in Nigeria?
significance of the study
The
importance of this research cannot be overemphasized because of its
immense significance to different groups of people who are in need of
information that it will provide. Its significance includes the
following:
The study will enable the management of flooding and
provide an in-depth understanding and knowledge of the flood prevention
strategies available so that they can adopt them adequately.
The
study will also serve as a source of secondary data for students and
scholars who intend to carry out similar studies in the future.
Scope/Limitation of the scope
The
scope of this study in terms of its content is restricted to the flood
effects on road durability with special attention to Makurdi the state
capital of Benue state.
