The huge demand for used imported vehicles
and poor restrictions are causing traffic congestion and worsening air quality
in most cities in Africa, environmental experts say.
"India and Africa share the same
problems and we have to share experiences to find solutions to the problem of
air pollution," she said.
"Nairobi, Dehli and other cities in
the South need second generation action, including technology leapfrog, scaling
up of public transport, integrated multimodal transport options, car restraints
and walking for clean air."
The dialogue, which was organised by CSE
and the Media for Environment, Science, Health and Agriculture (MESHA-Kenya),
sought to raise the understanding of experiences of cities in India and Africa
on air pollution among journalists.
Environmentalists at the dialogue said the
rapid expansion in the vehicle population, mining and manufacturing and higher
energy demand have resulted in high emission rates of major air pollutants
resulting in a deterioration of the ambient air quality in major cities across
the rapidly urbanising African continent.
They said vehicle import statistics for
Africa are not known and are not easy to give an estimate.
"The stock of vehicles is quite old
and most African countries are failing to enforce vehicle emission control
policies," said Prof Nzioka Muthama of the University of Nairobi.
"Disjointed policies and vehicle
import tariff regimes and the absence of emission standards mean that most
African countries will continue to be flooded with imports of low-cost
second-hand vehicles that do not meet strict emission standards of the
countries of their origin."
Prof Shem Wandiga, director of the
Institute of Climate Change at the University of Nairobi, said the rapid
increase of motor vehicle traffic with most African countries having limited or
non-existent standards for vehicle import and emissions and poor fuel quality
resulted in the importation of old second hand vehicles using fuels with high
sulphur levels which consequently increased air pollutant emissions.
Emissions, he said, introduced pollutants
which directly and indirectly altered the quality of air and resulted in
undesirable effects on man, animals, vegetation and materials.
He also said that limited transport
planning and management in urban areas had resulted in inadequate provision of
public transport, inadequate investment in infrastructure for motorised
transport, non-motorised transport and pedestrian traffic.
This, Prof Wandiga said, reduced urban
mobility options, increasing traffic congestion and air pollutant emissions.
Health experts say dirty air can cause lung
damage as well as heart diseases, strokes and cancer.Last year, the World HealthOrganisation estimated that one in eight deaths worldwide resulted from air
pollution.The UN health agency found that air pollution in African homes
contributed to nearly 600 000 deaths in 2012.
Africa had the third highest level of
deaths per capita from indoor air pollution of any region of the world, though
it was still well behind the western Pacific region including China and
South-East Asia.WHO figures for deaths per capita from outdoor air pollution in
Africa are still below the world average as lack of data is a major barrier.
Pollution monitoring is still minimal in
Africa which faces numerous other problems. Lack of air pollution equipment,
financial and human resources still affect air pollution control systems in
Africa.Only the WHO assesses outdoor pollution in Africa by drawing from
satellite data, inventories of pollution sources, air current modelling and
occasional ground monitoring.
In Zimbabwe, second-hand car imports
gobbled US$469 million in 2014 alone despite a 2010 Government ban on the
importation of vehicles older than five years to curb pollution.According to
the Zimbabwe Statistics Agency, more than 4 500 new vehicles were imported last
year and these mainly included brands such as Toyota, Nissan, Isuzu and Mazda,
all from Japan.
Should
Zimbabwe ban the importation of second hand vehicles and what are your reasons?
