GENETICALLY MODIFIED TOMATOES IN NIGERIAPresented by: Jan Döhring, Victor Marton, Matthew Thomson, Rachel Girimonte
Paper by: Enujeke, E.C & Emuh, F.N.
RELEVANCE
Sustainable Development Goal: Reducing famine
795 million affected
Focusing specifically on the Asaba area of Delta State
HEALTH EFFECTS
Long term health effects of GMOS unknown
Tomatoes are great sources of anti-oxidants, minerals, and vitamins
Relatively low calorie count, with an average of 18 per 100 g
THE PROJECT
Funded by Department of Agronomy at Delta State University
Research Question: Which of the five varieties of tomatoes tested is
most suitable for increased yield in the study areas?
THE METHODS Types: DT97, Roma VF, UC82B, Asaba Local, Kwale
Local
Conducted during the 2011 – 2012 cropping season
Typically humid environment, peaks in July and September, very dry in August
Annual mean rain: 1.65L
Annual mean temperature: 37.3°C
Annual mean humidity: 73.2%
Geomorphology: Ancient metamorphic crystalline basement complex
More acidic than basic
THE METHODS (CONT.).
Planted each type of tomato, then recorded their growth and other features at weeks 4, 6, 8, …
Compared various types of tomato (including GMO)
Nursing beds very acidic
pH (H20) 5.3
388.85 m2
Fertilizer used, weeded every two weeks
RESULTS
UC82B shows greater height, number of leaves, and flowers per plants than other varieties of tomato
RESULTS (CONT.).
UC82B also had the greatest yield, both in number and weight
THEORY OF KNOWLEDGE ASPECT
Areas of Knowledge: Ethics
Should we use GMOs to decrease famine?
Should we be allowed to change DNA?
Natural Sciences Advances knowledge into genetic modification and how it
affects growth
Testing limits of the plant’s growth
PROS
Utilitarianism Best result for most people
Altruism/Empathy Compassion
Communitarianism Take care of our fellow
CONS
Health effects could be negative No conclusive data on long-term effects of GMOs
Playing God – altering nature could have an adverse affect that we cannot foresee yet
Do humans have the right to alter nature?
Plants first, then a slippery slope to human genetic modification
IN CONCLUSION
UC82B shows an increased food yield, which can help end famine
Morally, it is our obligation to help end famine
Pros greatly outweigh the cons
