Good Practice in Essay Writing
• Introduction – including specific aim of the essay and brief overview
of structure followed (ie. in your words from the start!)
• Main body –
– Contrasting views and your analysis to show your understanding
– Use diagrams where possible to cut the waffle
– Always reference secondary data / views in text of essay (author, year) eg.
(FAO, 2000; UNEP, 1997; DEFRA, 2003; Dougill, 2003)
– Logical flow to arguments
• Conclusion – synthesis of main views and your views on key
messages for future
• Reference list – write out in full sources used – essential for all
coursework, though not expected in exam!
Social / Political Context
• MDG 1, Target 2 – “Halve between 1990 and 2015, the proportion of
people who suffer from hunger”
• In South Asia the challenge is improving the distribution of plentifully
available food
• In Sub-Saharan Africa the challenge also involves agricultural
productivity
• UNDP HDR2003 states that – “Increased investments are needed to
research and develop better technologies &
disseminate them through extension services.
Yet public investments and donor support for
agriculture have fallen in recent decades”
• FAO 2004 – “genetic engineering is a
‘global war of rhetoric’ …biotechnology can
overcome production constraints that are more
difficult or intractable with conventional breeding
.. But it’s not a panacea”
Genetic Modification of Food
• Genetic Modification (GM) – “involves moving genetic material from
the cells of one organism to those of another, be they related or
unrelated” (DEFRA, 2003)
• The first GM plants were bred in the 1980s, and the first commercial
crops were grown on a large scale in 1996.
• Globally, the four main GM crops being grown commercially are
soybean (62 % of global soybean), maize (19 %), cotton (13 %) and
oilseed rape (5 %).
• In 2002, GM crops grown worldwide covered twice the land area of
Britain (58.7 million hectares)
• Globally, approximately 6 million farmers in 16 countries (7
developed; 9 developing) grow GM crops, with 75 per cent of these
farmers coming from the developing world

GM – Scientific Context

An acceptance that major communication / public
awareness required, but an assumption that GM crops are
here to stay and that need to ensure benefits reach
developing nations
• Stress need to move away from opinionated views on ‘good’
or ‘bad’ to recognise that must assess safety of each new
product on its own individual merit
• UK field trials showed that GM maize had no detrimental
impact on soil biodiversity of fields; beet and rape
significantly reduced biodiversity
GM Nation?
• An unprecedented event of an open, inclusive public debate before
any change in public policy
• Designed to inform policy and to raise public awareness beyond those
people taking part
• Funded by DEFRA (£650k) & designed to cover the full range of
issues raised by GM technology
• Open Debate - Involved 675 public meetings on range of scales (c.
25,000 people); web-site that had 2.9 million hits from 24,609 visitors
during active phase (60 % response rate); 1,200 letters or emails –
36,557 completed questionnaires
• Narrow-but-Deep Consultations – survey research on typical crosssection of public (not involved in open debate) over 2 week period
• Still > 0.001 % of UK public actively involved! – lowest relative
response rate from 16 – 19 year olds
GM Nation? The Main Findings
• People are generally uneasy about GM
• The more people engage in GM issues, the harder their
attitudes – narrow-but-deep group surveyed across 2 weeks
of information provision
• There is little support for early commercialisation
• There is widespread mistrust of Government and MNC’s
• There is a broad desire to know more and for more research
to be done – “no one knows enough at the moment”
• Developing countries have special interests
• The debate was welcomed and valued
Comparison to Your Views
• From a class of 100 there is 1 GM Nation respondent!?
• Vast majority believe public is right to be sceptical –
–
–
–
–
–
–
“still unclear as to what long-term effects will be”;
“it reeks of ‘playing god’”;
“messing with nature has proved dangerous in the past with mad cow disease”;
“not necessary as we have enough food in the world”;
“could have drastic consequences on biodiversity as we know it”
“will only benefit wealthy companies not the world’s poor as with baby milk
controversies”
• 8 people believe public is wrong to be sceptical –
– “don’t realise facts due to poor media portrayal”;
– “may be a solution to starvation and would produce ‘perfect’ looking food”
– “need to increase awareness and improve labelling of foods”
• Views on if GM met a public interest ( hunger) much more varied –
– “yes, it is the only way forward out of the poverty trap”;
– “no, these countries shouldn’t be used as guinea pigs”
– “need to assess public interest against potential risks more adequately”
UK Media Portrayal of GM debate Frankenstein Foods
• Much media attention and concern in tabloid press decrying
“unnatural” process
• Much confusion with mad cow disease and distrust of food safety
issues of great public concern since the early 1990s
• Campaigns driven by prominent Environmental groups (FoE,
Greenpeace) and media figures (Prince of Wales, celebrity chefs) taken on-board by producers / supermarkets due to consumer pressure
Some GM headlines in last 5 years –
“A Hot Potato”
•
•
•
•
“Frankenstein Food Fiasco” - Daily Express, 99
“Mutant tomatoes not to our taste” - Daily Mail, 99
“GM foods to avoid like the plague” - Guardian, 00
“Frankenstein foods - are we being hysterical?” London Evening Standard, 00
• => Catchy headlines helped turn Europeans so
strongly against GM foods, while Americans have
barely noticed their spread
The Science behind the Headlines
• Food safety scares (e.g. BSE, Foot and Mouth) & role of
biotech companies in not separating GM and non-GM crops
led to widespread public scepticism of the ‘science’
• The Royal Society wrote to press to complain that ‘bad
science’ was driving decision-making
– Globally, 25,000 field trials without any health consequences
• Refers to work of Dr Arpad Pusztai whose work on feeding
rats GM potatoes had shown potential harmful effects
• His work not published in scientific
journals & widely criticised, then ‘sacked’
& Govt funding withdrawn - led to portrayal
of a cover up
Changing Views of UK Govt
• Throughout scandal Govt favoured the continued
experimental investigation of the potential health and
biodiversity impacts of GM crops (in labs & field trials) due
to economic potential of technology • Bemoaned media handling of the issue, Michael Meacher
(2000) - “I think it has been largely a propaganda exercise rather
than the provision of factual information … We have done our best to
counter it with scientific consensus, but the power of the media is so
great that we have had no more than a marginal effect”
• However agreed that “no GM crops would be grown commercially
until we are satisfied there will be no unacceptable impacts on the
environment” (Tony Blair, 2000)
• But, go-ahead given to commercial GM maize production
after field trials and EU agreement (9th Sept 2004)
UK - Lessons to be Learned
• The Precautionary Principle drives the need for more
scientific investigation, but uncertainty in scientific
messages prone to mis-representation
• Public concerns (over role of science and MNC’s) and
consumer patterns are more important drivers of change
than scientific arguments or Government support
• Health and environment remain high on the agenda and
unlikely that UK public views will change even with further
scientific studies
GM Views and Environmentalist Perspectives
Different stakeholders expressing views that match their philosophical
views on human-environment relations: • “New (GM) rice was created through public research and should be available to all.
For developing world countries and their starving millions, it is life or death”
– Prof Anthony Trewavas, Univ of Edinburgh (from Guardian,99)
– Technocentric viewpoint
• “The biotech industry has been forced to use poverty and malnutrition as a
justification for its continued (commercial) existence”
– Dr Sue Mayer, GeneWatch UK (from Guardian, 1999)
– Ecocentric viewpoint
• “GM takes mankind into the realms that belong to God alone”
– HRH Prince of Wales, 1998
– Theocentric viewpoint
Hunger and GM
• GM Nation recognised that developing countries have special interests
and class this as “debate within the debate”
• Active participants reject view that GM could benefit developing
countries, by a majority
• Narrow-but-Deep sample supported use of GM and this support
increased as they became more engaged in issues
• Opposition based less on negative feelings to GM, but more on the
view that there are better ways to promote development (fair trade,
better food distribution, better governance etc.)
• People sceptical as to whether MNC’s will
deliver benefits to people of developing world
GM - An African perspective
• Clear message delivered to OECD Conference on Food Safety, July
2000 (quoted from Krebs, 2000)
• “We would like to be like you, with plenty of food for our people. We
need every tool at our disposal to achieve this, including
biotechnology, which will allow us to grow things without costly
chemicals and irrigation systems we cannot afford”
• “GM may be better for Africa than older technologies, like those of
the Green Revolution .. Which failed Africa because it came from the
West”
– Wambungu, 2000
• Many African opponents –
• “Africa’s genetic resources are being exploited by
global transnational corporations”
– Wangari Maathai, 2004

Cassava research: West African success story
• Cassava root - excellent energy source; leaves rich in vit A,
C, Fe and Ca
• New varieties produced using biotechnology (crossbreeding) in 1980s; reduced undernourishment markedly Ghana from 62 to 10%; Nigeria 44 to 8% (1981-1998)
• Improved drought resistance crucial
