What is biotechnology? Narrower view: Some use term only to refer to newer tools of genetic science

13
In the narrow sense, biotechnology can also refer to recombinant DNA technology (genetic transformation)
14
i.e., transferring genes from one organism to another to produce a Genetically Modified Organism (GMO)
15
Unfortunately, there has been much hysterical and misinformed criticism of GMOs
17
With rare exceptions, this criticism has been unwarranted and counterproductive
18
The main concerns about GMOs are : Food safety.
19
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)
20
In fact, food safety and human health can be improved
21
Bt transformation reduces mycotoxin development in maize considerablyBt transformation reduces mycotoxin development in maize considerably
22
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 farmersIn China, where GMOs are used widely, there has been a great reduction in pesticide poisoning of farmers
23
The main concerns about GMOs are : Food safety.Environment.
24
All farming impacts the environment, regardless of GMO usage
25
Primary concern: Movement of transgenes to wild species (enhanced vigor of weeds and reduced genetic diversity in natural ecosystems)
26
Transgenes do not move more frequently or readily than ordinary genes
27
Genes are genesGenes are genes Transgenes do not move more frequently or readily than ordinary genes
28
Genes are genes Transgene movement occurs via natural pollination, hybridization)Transgene movement occurs via natural pollination, hybridization) Transgenes do not move more frequently or readily than ordinary genes
29
Non-GMO plants to which transgenes move must be closely related to the GMO
30
Only good example: Round-up ready canola in Canada
31
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
32
GMO usage is usually environmentally neutral, but in some cases environment can be improved
33
ex.: Use of herbicide- resistant crops in reduced tillage systems reduces erosion, soil degradation
34
The main concerns about GMOs are : Food safety. Environment.Multinationals.
35
Multinationals do hold sway in industrialized countries
36
However, there is nothing to stop GMO development in developing countries
37
Multinationals are not interested in most tropical crops (bananas, cassava, yams and millet are good, African examples)
38
For these crops, there is great potential in developing countries
40
The main concerns about GMOs are : Food safety. Environment. Multinationals.Trade.
41
In Africa, major concern is over trade with Europe (e.g. GM-corn in Zaire)
42
Two important points: Europe is not the only market. ex.: China and India are potentially much larger markets
43
Trade should be of secondary concern where hungry populations exist
44
The main concerns about GMOs are : Food safety. Environment. Multinationals. Trade. Ethical issues.
45
Complicated, often personal issue
46
Relevant question: “What is the risk if this technology is not accepted?”
47
Despite concerns, biotechnological research, including the development of GMOs, is conducted in Africa

IITA - International Institute of Tropical Agriculture ILRI - International Livestock Research Institute WARDA - West Africa Rice Development Association World Agroforestry Centre (ICRAF) CGIAR centers in Africa address problems in international agriculture
