DUNGU, TAMALE– Urban
and peri-urban agriculture (UPA) covers between 5 percent and 36 percent of a
city’s total food supply and up to 90 percent of its fresh vegetable
consumption, a team of African-German agriculture scientists and researchers currently
conducting a study in Tamale under a project called Urban Foodplus say.
Accordingly, the team comprising animal scientists,
water engineers, social anthropologists, economists, geographers as well as
plant and soil scientists, observed that in view of increasing population in
cities and towns, farming should be highly encouraged in such places since the
practice has the potential to increase high yields to enhance food security.
Currently, Africa’s population is about 1.1 billion
and by 2050 it is projected to hit 2.4 billion, with sub-Saharan Africa,
currently 900 million-plus, swelling to 2.2 billion according to a recent study
by the Population Research Bureau, a Washington-based outfit. This is because
Africa’s total fertility rate—the number of children a woman can expect to have
in her lifetime—is 4.7. The figure in America is 2.0; in East Asia 1.7. By 2050,
a quarter or half of the continent’s population will migrate from the rural
areas to live in urban centres where there are more social amenities and relative
comfort.
According to The
Economists, the prospect of so rapid a rise has triggered a host of
Malthusian fears, on the continent and elsewhere. If Africa is struggling to
feed a billion people, it is hard to see how it could feed 4 billion in future.
Though the past decade has been relatively peaceful, perhaps a population boom
will fuel civil strife. And surely, some fear, the expanding masses will destroy
what is left of Africa’s flora and fauna, wiping out endangered species and
pouring concrete on primal forest and grassland.
For instance, as a result of persistent rural-urban
migration in Ghana over the years, many migrants have resorted to farming and
rearing of animals in every little space they find to squat in their new place
of destination. They suddenly find farming close to market centres very lucrative
since consumers relish fresh vegetables, and quiet apart from that, a farmer does
not have to spend so much on transportation.
Leader of the Team of the African-German Researchers
Professor Bernd Marschner told Savannahnews, that the project intends to enhance resource use efficiency in UPA for
improved food security in West African cities.
He, however, observed that, little is known about how
to overcome problems in resource use efficiencies and intimated that, the
researchers are to make sure farmers are able to overcome the problems
associated with UPA so as to improve food security.

“Our aim is to reduce the risks associated with eating
vegetables produced through the use of waste water and other unapproved ways of
farming so that the consumer’s health is not at endangered. Vegetables produced
with waste water are often infected with pathogens and other diseases that can
harm or kill humans when they eat them. We are using simple technologies such
as biochar as a water filter and organic fertiliser in place of chemical
fertilisers to address some of these challenges posed by UPA”, Prof. Marschner
emphasised.
Using waste or polluted water to water gardens
especially during the dry season is a common practice in many towns and cities
in Ghana including Tamale. Consumers often have to contend with using salt or
vinegar to wash vegetables thoroughly and after that, cook it for a while to be
sure the germs are all killed before they eat it.
The researchers have already formed a partnership with vegetable growers at Zagyuri, a suburb of Tamale to conduct experimental test on crops and perhaps establish the effect of using waste water from the Kamina Military Barracks to irrigate their gardens.
A research scientist at Savannah Agriculture Research
Institute Abubakari Mutari, who participated in a workshop organised by the
African-German researchers, appealed to chiefs in the Tamale Metropolis and other
parts of the country to deliberately allocate land to vegetable growers to
enhance food security in urban and peri-urban areas.
He commended the researchers for their interest in
Africa’s agriculture and food security and quick to add that, the team is
building on projects that CSIR-SARI have done in the past and continue to do
to ease the challenges posed by UPA.
Urban Foodplus is spearheaded by the Universities of
Kassel and Bochum. It also aims at addressing challenges of soil fertility and
water scarcity in order to promote urban food crops production in a number of
cities in West Africa.
Funded by the Federal Ministry of Education
and Research
to the tune of 7 million Euros, the researchers are partnering with fourteen
African institutions including the University for Development Studies, Centre
for Scientific and Industrial Research among others. The research is taking
place concurrently in Tamale and Ouagadougou-Burkina Faso, and will later be
extended to other West African cities including Bamenda-Cameroon and Bamako-Mali.
