ABSTRACT

 

Article No.: 070519126

Type: Review

 

 

Crop production,
food security, human health and economic activities in Sub-Saharan Africa
are affected by many factors, including population dynamics, conflicts, crop
diseases and recurrent climate change. Quantity and quality of crop yields
are falling due to influences from these factors. The combined impacts of
these factors invariably lead to poor access to nutrient-rich foods, severe
hunger and massive increases in the prevalence and number of people living
with protein-calorie malnutrition or vitamin-mineral deficiencies (VMD) in
sub-Sahara Africa (SSA) and some parts of Asia. So far nearly 2 billion
people in these regions are malnourished while 1 billion others suffer
severe hunger. Classical strategies of crop improvement through conventional
breeding programs for higher crop yields, nutrients enrichment, resistance
to pests, diseases and other environmental stressors; or for improved water
and fertilizer use efficiency are time consuming.  Lack of useful genotypes (germplasms) also
hampers the effective use of conventional approaches for crop improvement.
Against this backdrop, availing growers with improved crop varieties requires
a huge time lag. Overcoming these challenges will necessarily require a
comprehensive approach involving combining classical breeding, with modern
frontier agricultural technologies. Agricultural technologies  such as immunization and biotechnology
(genetic engineering) have strong potentials towards contributing to the
development of  healthier, higher
yielding GM seeds, climate smart cultivars with capacity to endure salinity,
soil reactions and disease, as well as transgenic varieties dense in essential
nutrients and presenting improved appearances compliant with mechanization.
Above all such GM varieties genetically equipped for early maturity are in
all wise welcome especially in hunger prone, highly malnourished conflict
ridden and extreme weather affected localities including sub-Saharan Africa.
In the light of these therefore, this article reviewed the significance of
biotechnology on crop improvement, human nutrition and health using
available literature published between 1987-2018; and the outcomes of the
review are hereby presented and discussed.
