Unilorin set to be among world top varsities—US don

A renowned Professor of Mathematics at Arizona
State University, USA, Abba Gumel, has tipped
the University of Ilorin to be among the top rank
universities in the world within the next four
years because of her visionary leadership and
excellent management.
Prof. Gumel stated this last Monday (May 25,
2015), when he paid a courtesy call on the Vice-
Chancellor, Prof. AbdulGanuyu Ambali (OON), in
his office shortly before delivering a public
lecture organised by the Centre fot International
Education (CIE), University of Ilorin.
At the lecture, entitled “Mathematical
Assessment of the Role of Climate on Vector-
Borne Diseases”, the Arizona University don
submitted that climate change could cause a
devastating increase in Vector-Borne Diseases
(VBD) burden and expansion of geographic range
of the vectors.
Prof. Gumel said, “Climatic factors, such as
temperature, humidity, rainfall and vapour
pressure, significantly affect the incidence of
BVDs either through changes in the duration of
vector and parasite (pathogen) life cycles, or
influences on host, vector, or parasite behaviour.
Increases in average global surface temperatures
since the 1950s and the trend is expected to
continue over this century.”
According to the Guest Lecturer, a warmer
climate could increase malaria burden, adding
that it is believed that malaria epidemics can be
predicted from climatic indicators and climate
forecasts. He said, “Increases in temperature
cause female adult anopheles mosquitoes to
feed more frequently, while warmer waters
shorten the juvenile incubation period leading to
a faster maturation period of vector larvae”.
Prof. Gumel warned that the Sub-saharan Africa,
where the overwhelming majority of malaria
burden is currently concentrated, is expected to
experience greater temperature increases than
the global average.
He said also that as the global temperatures
increase, a shift in the distribution of vectors into
non-endemic areas may occur, so that malaria-
endemic areas at lower temperatures may
experience an increase in incidence, while
regions at temperatures beyond the transmission
peak are likely to experience a decline in
incidence.
Prof. Gumel said, “The species involved in the
transmission dynamics of mosquito-borne
diseases, such as malaria, are affected by
various abiotic (physical/non-biological)
conditions such as temperature, precipitation,
humidity and vapour pressure. Many life history
features both of the malaria vector and the
parasite are sensitive to temperature and the
presence of aquatic habitat for mosquito
breeding.”
The Professor of Mathematics disclosed that
empirical studies show that in general, rates of
larval mosquito survival and development, biting
and pathogen replication rates increase with
increasing temperature up to an optimum value
and then decrease rapidly as lethal temperatures
are approached.
He noted in contrast that the survival of adult
mosquitoes tends to decline with increasing
temperature.
Earlier in his opening address, the Vice-
Chancellor of the Univrsity of Ilorin, Prof. Ambali,
stated that the University has a visionary and
positive agenda, adding that it is committed to
being ranked among the top universities in the
world.
Prof. Ambali pointed out that the University has
committed staff that are ready to work and take
the University to greater heights. He then
expressed the desire of Unilorin to have a
workable Memorandum of Understanding (MoU)
with the Arizona State University.
The Vice-Chancellora described the lecture topic
as important, noting that all disciplines are
interrelated.
