1.2: SIGNIFICANCE OF STUDY
Worldwide,
coastal areas are the most exploited in terms of urbanization due to
their abundance in natural resources that can provide humans with many
ecosystem services that are important to support livelihoods and
economic activities (Kron, 2008).
The level of disturbance and
effect of urbanization on natural process in coastal regions are fast
becoming a nightmare, some of which are expected to become more serious
due to changing climate (Satterthwaite, 2010).
Hence, this study
examines and analyzes climate change and variability in Lagos coastal
region using temperature and rainfall measurement as a parameter over a
specific duration (30years). This study also highlights the impacts of
climate change to coastal regions that invariably may contribute to
accentuated environmental disasters and the exacerbation of health
risks.
1.3: AIM AND OBJECTIVES OF THE STUDY.
1.3.1: AIM
The aim
of this study is to assess the climate trends for Lagos region and the
consequences on the coastal environment in order to develop an
appropriate climate change adaptation strategies for Lagos coastal
region.
1.3.2: OBJECTIVES.
The specific objectives are:
v To examine the rainfall and temperature trend in Lagos region (1981-2010)
v To assess the relative consequences of the climatic trends socio-economic activities and environment in Lagos region.
v To evaluate appropriate adaptation strategies towards sustainable Lagos coastal environment.
1.4: STUDY AREA
1.4.1: GEOGRAPHICAL BACKGROUND
Lagos,
a state in Nigeria is the study area of this research. It is a
commercial centre in Nigeria with a total of about 17 million
inhabitants, a yearly growth rate of 3.2% and second most populous city
in the country (Census, 1996). It is the fifth largest city in the
world, is the foremost manufacturing and port city in West Africa, and
the hub of business and economic development in Nigeria (BNRCC, 2012)
