Food
Security in Nigeria: Is Biotechnology the Panacea?
In the last fifty years, the
Nigerian population has escalated at geometric proportion. Data available in
the 2012 revision of the World Population Prospects by the Population Division
of the Department of Economic and Social Affairs of the United Nations
Secretariat, indicates that Nigerian population in 1950 was only 37,860,000 compared
to 159,708,000 in 2010. The proportion of children below the age of 15 in 2010
was 44.0% while between 15 and 65 years was 53.2% and above 65 years was only 2.7%.
In my article of 15th July, 2016, published on this page, I quoted a brilliant demographic analysis made by
Sanusi Abubakar, an ace columnist of Daily Trust Newspaper, published in its
edition of Tuesday 28/6/2016. His analysis shows that Nigeria has an average
birth rate of 850 babies per hour and an average death rate of 280 people per
hour giving a population increase of 570 people per hour, 13,491 people per day and 4.92 million people
per year. At this rate, Nigeria will reach 263 million by 2030 and 400 million
by 2050, which will make the country to be the third most populous in the
world. Currently, the population of Nigeria represents 2.35 % of the world´s
population. This arguably means that one out of 43 persons on this planet is a
Nigerian. With this exponential rate of population increase, the question; how
can Nigeria be food secured? This question should disturb every responsible
Nigeria; a leader or led, a rich or pauper a resident or nonresident, an able
or disable.
The challenge of making Nigeria food
secured is a herculean one, considering the current trend in food production,
which has made the country to resort to massive food importation. Food imports
in Nigeria have been growing at an alarming rate of 11% per annum since the
1980s. From recent government statistics (ATA documents), Nigeria was reported
to be the world largest importer of wheat from USA with an annual import of
N635 billion. It was also the second largest importer of rice (N356 billion),
sugar (N217 billion), fish (N97 billion) and many other staple food items.
These agricultural commodities have great local production potentials
nationwide. In addition to these potentials, Nigerian arable land is estimated
to be 79 million hectares of arable land out of which 32 million hectares are
cultivated. The cultivation is done by smallholders, mostly
subsistence producers, which account
for 80% of all
farm holdings. Again, about 90% of crops production in Nigeria is under
rain-fed condition making the cultivated land a mere 100 % cropping intensity.
This is currently the picture of Nigerian population and food (in) security. With
more population, more foods will be needed on the table as there is no
alternative solution to hunger except food. How can Nigeria produce sufficient
foods to meet the requirements of this teeming population?
There are several challenges
militating against food production in Nigeria. These problems are diverse and
interlinked with each other. This column lacks space and time to list and
analyze all the problems of agriculture in Nigeria. Some of the problems can be
addressed by good government policy
formulation and implementation to provide clear direction on agricultural
development. However, scientific approach to address some of the challenges on
sustainable manner is pertinent and timely. Challenges such as pests, diseases,
inadequate rainfall for some agricultural commodities or early cease of
rainfall can be scientifically addressed using biotechnology. Exponential increase
of yield per unit land, reduction of maturity time of crops and animals and
increase of products quality are easily achieved using biotechnology. what is
biotechnology?
Wikipedia defines biotechnology
as the use of living systems and organisms to develop or make products, or
"any technological application that uses biological systems, living
organisms or derivatives thereof, to make or modify products or processes for
specific use" Depending on the tools and applications, it often overlaps
with the related fields of bioengineering, biomedical engineering, bio-manufacturing,
molecular engineering, The wide concept of "biotech" or
"biotechnology" encompasses a wide range of procedures for modifying
living organisms according to human purposes, going back to domestication of
animals, cultivation of the plants, and "improvements" to these
through breeding programs that employ artificial selection and hybridization.
The use of the biological processes of
microorganisms to make useful food products, such as bread and cheese, and to
preserve dairy products have been in existence for centuries. These biological
processes are simple form of biotechnology. Over the years, biotechnology has
grown to provide
breakthrough products and technologies to combat debilitating and rare
diseases, reduce our environmental footprint, feed the hungry, use less and
cleaner energy, and have safer, cleaner and more efficient industrial
manufacturing processes. Recent information shows more than 250 biotechnology
health care products and vaccines available to patients, many were hitherto untreatable
diseases; diseases that were considered "end of the road", are today
vaccinated courtesy of biotechnology. In the areas of agriculture, more than
13.3 million farmers around the world use agricultural biotechnology to
increase yields, prevent damage from insects and pests and reduce farming's
impact on the environment. And more than 50 bio-refineries are being built across
North America to test and refine technologies to produce bio-fuels and
chemicals from renewable biomass, which can help reduce greenhouse gas
emissions.
In the last centuries, as we continued
to receive more satisfying results from the use of biotechnology, more efforts were
made to elevate it to includes genetic engineering as well as cell and tissue
culture technologies. Genetic engineering, also called genetic modification, is
the direct manipulation of an organism's genome using biotechnology. It is a
set of technologies used to change the genetic makeup of cells, including the
transfer of genes within and across species boundaries to produce improved or
novel organisms. An organism that is generated through genetic engineering is
considered to be a genetically modified organism (GMO). The first GMOs were
bacteria generated in 1973 and GM mice in 1974. Insulin-producing bacteria were
commercialized in 1982 and the sale of genetically modified food commenced
since 1994 in United State. Genetic modification involves the mutation,
insertion, or deletion of genes. Inserted genes usually come from a different
species in a form of horizontal gene-transfer.
Genetically modified crops (GMCs, GM
crops, or biotech crops) are plants used in agriculture, the DNA of which has
been modified using genetic engineering techniques. In most cases, the aim is
to introduce a new trait to the plant which does not occur naturally in the
species. Examples in food crops include resistance to certain pests, diseases,
or environmental conditions, reduction of spoilage, or resistance to chemical
treatments (e.g. resistance to a herbicide), or improving the nutrient profile
of the crop.
Globally, farmers have widely adopted
GM technology. Literature reveals that between 1996 and 2015, the total surface
area of land cultivated with GM crops increased by a factor of 100, from 17,000
km2 (4.2 million acres) to 1,797,000 km2 (444 million acres). It was also
reported that 10% of the world's arable land was planted with GM crops in 2010.
In the US, by 2014, 94% of the planted area of soybeans, 96% of cotton and 93%
of corn were genetically modified varieties. Use of GM crops expanded rapidly
in developing countries, with about 18 million farmers growing 54% of worldwide
GM crops by 2013. A 2014 meta-analysis concluded that GM technology adoption
had reduced chemical pesticide use by 37%, increased crop yields by 22%, and
increased farmer profits by 68%. This reduction in pesticide use has been
ecologically beneficial, but benefits may be reduced by overuse. Yield gains
and pesticide reductions are larger for insect-resistant crops than for
herbicide-tolerant crops. Yield and profit gains are higher in developing
countries than in developed countries. What are the progress made in using biotechnology
to develop Nigerian agriculture? who made them? What are the challenges and
implications? (To be continued)
