Biotechnology and GMOs in Africa: Unrealized Potential Randy Ploetz University of Florida, IFAS Tropical Research & Education Center Homestead
What is biotechnology? Broad view: Applied biology
What is biotechnology? Broad view: Applied biology • Application of biological knowledge and techniques to develop products
P. Namanya National Banana Research Programme Uganda
What is biotechnology? Broad view: Applied biology • Application of biological knowledge and techniques to develop products • Use of living organisms to make a product or run a process
Banana wine Tanzania
What is biotechnology? Broad view: Applied biology • Application of biological knowledge and techniques to develop products • Use of living organisms to make a product or run a process • Classical plant and animal breeding, fermentation and enzyme purification
What is biotechnology? • Narrower view: • Some use term only to refer to newer tools of genetic science
What is biotechnology? • Narrower view: • Some use term only to refer to newer tools of genetic science • Examples: • Marker Assisted Selection (MAS)
What is biotechnology? • Narrower view: • Some use term only to refer to newer tools of genetic science • Examples: • Marker Assisted Selection (MAS) • Pathogen & pest detection and identification
In the narrow sense, biotechnology can also refer to recombinant DNA technology (genetic transformation)
In the narrow sense, biotechnology can also refer to recombinant DNA technology (genetic transformation) • i.e., transferring genes from one organism to another to produce a Genetically Modified Organism (GMO)
Unfortunately, there has been much hysterical and misinformed criticism of GMOs
Unfortunately, there has been much hysterical and misinformed criticism of GMOs With rare exceptions, this criticism has been unwarranted and counterproductive
The main concerns about GMOs are : Food safety.
The main concerns about GMOs are : Food safety. No food safety problems have been identified in the “big experiment” (USA ca. 300 million people over 10 years)
In fact, food safety and human health can be improved • Bt transformation reduces mycotoxin development in maize considerably
In fact, food safety and human health can be improved • Bt transformation reduces mycotoxin development in maize considerably • In China, where GMOs are used widely, there has been a great reduction in pesticide poisoning of farmers
The main concerns about GMOs are : Food safety. Environment.
All farming impacts the environment, regardless of GMO usage
All farming impacts the environment, regardless of GMO usage Primary concern: Movement of transgenes to wild species (enhanced vigor of weeds and reduced genetic diversity in natural ecosystems)
Transgenes do not move more frequently or readily than ordinary genes
Transgenes do not move more frequently or readily than ordinary genes • Genes are genes
Transgenes do not move more frequently or readily than ordinary genes • Genes are genes • Transgene movement occurs via natural pollination, hybridization)
Non-GMO plants to which transgenes move must be closely related to the GMO
Non-GMO plants to which transgenes move must be closely related to the GMO Only good example: Round-up ready canola in Canada
Non-GMO plants to which transgenes move must be closely related to the GMO Only good example: Round-up ready canola in Canada Round-up ready canola not used where it is a concern
GMO usage is usually environmentally neutral, but in some cases environment can be improved
GMO usage is usually environmentally neutral, but in some cases environment can be improved ex.: Use of herbicide-resistant crops in reduced tillage systems reduces erosion, soil degradation
The main concerns about GMOs are : Food safety. Environment. Multinationals.
Multinationals do hold sway in industrialized countries However, there is nothing to stop GMO development in developing countries
Multinationals are not interested in most tropical crops (bananas, cassava, yams and millet are good, African examples)
Multinationals are not interested in most tropical crops (bananas, cassava, yams and millet are good, African examples) For these crops, there is great potential in developing countries
The main concerns about GMOs are : Food safety. Environment. Multinationals. Trade.
In Africa, major concern is over trade with Europe (e.g. GM-corn in Zaire)
In Africa, major concern is over trade with Europe (e.g. GM-corn in Zaire) Two important points: Europe is not the only market. ex.: China and India are potentially much larger markets
Trade should be of secondary concern where hungry populations exist
The main concerns about GMOs are : Food safety. Environment. Multinationals. Trade. Ethical issues.
Complicated, often personal issue Relevant question: “What is the risk if this technology is not accepted?”
Despite concerns, biotechnological research, including the development of GMOs, is conducted in Africa
