N v S divide on technology use- S America relatively high. Asia & Africa low percentage
but Asian megacities (Mumbai & Shanghai) have high internet access levels.
Economics explains patterns.- Internet access costly in LDCs. Language-most
webpages in English, Chinese or Spanish. Electricity & access to computer. Content
needs to be what people want to use, Needs to be internet service providers.
Air travel- Some regions peripheral. Requires infrastructure(Airports), some global
regions poorly integrated into global economy so little demand for travel. Lack of
connections-new technology takes longer to reach places
Environmental determinism
more vunerable to environment due to
lack of technology. Agricultural
technology-crop production determined
less by environment & farmers less
vulnerable to hazards.-increases food
security. Subsistence farming lacks
this-need seed varieties, simple
irrigation & fertilisers, not GM crops
Agricultural technology & vunerability
Irrigation-provide
additional water for
crops during dry
periods/regions-
without, dry regions
produce fewer crops
in shorter season,
drought can lead to
crop failure.
Pesticides-Sprayed
on crops to kill
pests & increase
yields by
decreasing crop
losses- without,
crops vulnerable to
pest plagues
Fertilisers-Added
to soil to provide
additional
nutrients for
growth- without,
yields restricted
by natural
nutrients
Farm machinery- Used to
replace human labour &
increase efficiency-
without, size of farmed
area determined by
population & distance to
travel, crops abandoned
during floods/severe
weather-lack of people
Hybridisation-Inter
breeding of crop varieties
under controlled conditions
to produce disease/pest
resistance & higher yields-
without,Crops could
become vulnerable to
pests/disease
barriers & inequalities
Physical reasons-some renewable energy technologies are only suited to certain
physical locations e.g solar/wind power. HEP-suitable water supply & valley.
Political reasons- N Korea-internet access prevented by government to
control flow of information & ensure correct political message maintained
Environmental reasons-certain groups voluntarily shun certain technologies.Organic
farmers-no pesticides/cattle antibiotics due to negative environmental & health impacts.
Religious reasons- contraceptive technology rejected by some religions-Catholic
Military reasons- nuclear technology controlled by international nuclear non-proliferation
treaty-aims to prevent nuclear weapons falling into wrong hands. International Atomic Energy
Agency-ensures states with nuclear power do not use it to develop nuclear weapons.
New inventions protected by intellectual property rights, patent given to the inventor to protect copying,
inventors licence companies to manufacture new technology & receive royalties. Prevent drugs being
made widely- charge high price to recoup R&D costs. Illegal copies in China/Brazil for HIV/AIDS.
medicines, crop breeding to increase
yield-agricultural technology,
petroleum & nuclear technology.
Access to technology not evenly
distributed.(electricity,sanitation,
Internet access)
Technology & development
the technology gap
developed world increasingly knowledge based-monay made from ideas,information & services.- growth of
knowledge economy promoted by globalisation of free markets/free trade, information/communications technology,
networking using internet technology, high-tech products & services.
developing world still industrial-
Iphone- complex components made in
NICs/Japan, less complex
assembly-China. No role for least
developed-Africa
R & D spending- globally $1 trillion- USA-1/3-most research personnel. technological innovations-2007-51% patents in
USA, 20% Japan, 16% EU. MDC governments & TNCs invest in R&D, high university funding-graduates
leapfrogging
R&D hard for developing world- skilled researchers required, need
investment in universities, most R&D by TNCs in MDCs, government
budgets used for water/housing projects- little spare money, lab/research
facilities expensive. NICs(Taiwan/S Korea-Samsung) big R&D spenders
Examples- Mobile phones without landlines, Laptops
& wifi without broadband & computers, Solar
panels/HEP without complex electricity transmission
grid, GM crops.
Mobile phones-leapfrogged landlines-
requires installation of masts-limited
signal coverage, electricity to
charge-villages have car chargers.
Increases ability to search for jobs,
keep in touch with family, access
market prices, warn of natural hazards.
Lifestraw-Water purification-
leapfrogged water purification &
distribution network, 30cm tube,
purifies water using
filters-portable & lasts 1yr. Major
health improvements- kills all
bacteria & parasites.
Problems- developed
world origins- MDCs
collect royalties & profits
costs & benefits
externalities-unforseen impacts of technology-not accounted for in final costs
of production.- unforeseen environmental impacts leading to social polarisation
Green revolution- increased food supply
in Asia, had to be redeveloped every few
years as effected by pests & disease.
Impacts- Economic-Yields dramatically
increase, 2 crop harvests per year, increased
food security, Social- Machinery
introduction-unemployment & increased urban
migration, only well off farmers can afford,
improved health & diet. Environmental-
Increased fertiliser use-nutrient rich runoff &
eutrophication, pesticide over-spray damages
biodiversity, some HYV monocultures wiped
out by pests/disease.
gene revolution- much of production exported
as fibre(cotton)/Cattle fees(maize/soy), food
security often not increased.
Aim- Genetic makeup of crops(maize,cotton,soy)
altered so they are pest,disease,herbicide,drought
resistant. yields & food/income security increase
Impacts- Economic-Farmers more
dependent on seeds/chemicals from TNCs,
Some yields not increased, Increased
exports/rising farm incomes. Social- Public
reject technology(UK), Argentina-larger GM
maize farmers buy out smaller ones-social
polarisation, many crops for export not food.
Environmental- Weeds develop resistance to
herbicides, deforestation in latin America to
increase farmed areas.
dealing with externalities
more technology-greater environmental
impact- goods require resources-have to
be extracted & processed. Manufacturing
causes pollution, technology has to be
powered by fossil fuels- higher co2
emissions/global warming
impacts on humans/ecosystem wellbeing- rising
sea levels-flood costal cities, increased sea
temperatures-cause coral bleaching, increased
drought-crop failure & water shortages,
increased flooding-destroy homes.
increasing pressure to move to polluter pays model-
if people treat environment as pollution sink,have to
pay green taxation- EU emissions trading scheme
sets pollution quotas- can buy carbon credits, UK car
tax linked to co2 produced per km.
Technology, environment & the future
contrasting approaches
Intermediate technology
needs to be fit for
purpose-low cost & easy to
repair locally-
environmentally friendly.
Bottom up.
Alternative technology-lowest
environmental impact/pollution
e.g solar powered water
pump-NGO/TNC joint venture.
Intermediate technology-
low cost, simple, small
scale, local skills &
resources e.g Village hand
pump installed by NGO.
Mega-engineering
projects-one-off solution at
high capital cost e.g Large
dam funded by government
high tech advanced
technology e.g
bioengineering/electronics,
nanofiltrification systems
from TNC R&D labs
Big fix
Geo-engineering-
regional/global scale technology
that re-engineers the way the
planet works (global
warming/land degradation) often
transboundary-conflict
proponents-techno-fixes more
likely to work than persuasion
to change lifestyles(attitudinal)
precautionary principe-arguing
against technology as
unknown outcomes.
Past failure- Aral Sea disaster
Aim-Transform arid USSR land into
productive cotton-growing farmland
using mega-scale irrigation
Technology-Dams & diversions of rivers
to redirect flow along 40,000km of
canals to irrigate 3.5m hectares of land
Impacts/problems- Rivers dry up,
Aral sea shrinks to 25% of original
size, exposed sea bed scoured by
wind creating salt storms & farm
chemicals on people & land,
chemical pollution increases cancer,
fishing industry collapse, flora &
fauna in sea died out.
Future possibility-Artificial global dimming
Aim-Reduce solar input by creating an
artificial aerosol blanket in the atmosphere
to reflect sunlight back into space
Technology-aircraft/rockets/artillery/balloons
-shoot sulfur dioxide aerosols into
stratosphere to decrease concentrations
Impacts/problems- Aerosols cool
planet by reflecting incoming solar
radiation & promoting cloud formation,
calculating amount of sulfur dioxide
required difficult & could increase acid
rain, unforeseen climate alterations
Technology & sustainability
Need to maintain high
human wellbeing and
ecosystem-
environmental
sustainability
index(ESI)- high human
wellbeing(GDP), QoL
index.
Sustainability of technology
Economic- technology
must be cost effective &
affordable- no debt, costs
not passed to others.
Social- Benefit all parts
of society & not polarise
it, promote human
health & wellbeing
Environmental-produce
little pollution, not have
adverse consequences
for ecosystems
Resources-use
renewable resources,
power should avoid
fossil fuel use
futures
Several possible futures-
Divergent world-technological
advances in developed world, lack
of access in developing world.
widen development gap- rely on aid
Convergent world- increased
transfer of technology to developing
world. bridge development gap.
current patenting & licensing does
not allow. Intensify global warming
Switch to renewable resources for
making & powering technology.
Fossil fuels-environmental issues,
economic uncertainty(running out)
LDCs- technology transfer relies on
NGO development work (UK
government).
2008-Global Environment Facility(GEF) given responsibility for technology
transfer to developing world-energy efficient lighting & appliances, efficient
& renewable power generation, fuel-cell buses -$3Billion annual budget-
support of 180 countries- trying to prevent use of fossil fuels-stop global
warming-needed for development & environmental sustainability
Synoptic links
Players- technology developed by TNCs- research innovations-GM crops,
new drugs & IT applications. Technology rapidly adopted in developing
world-NGOs responsible for introducing appropriate & intermediate technology
Actions- High tech/big fixed favoured by governments-visible solutions to
national problems(three-gorges dam) Intermediate. appropriate
technology-local & favoured by grass roots.sustainable development
Futures- Business as usual- developed world adopting new technology,
developing have limited access. More sustainable-Wholesale technology
transfer to developing-Improve QoL. Enhanced by radical adoption of
renewable technology to replace energy intensive,polluting technologies in
transport & energy supply e.g geo-engineering solutions
Links to other units-Unit 1-World at risk- technology may play role in managing
global warming e.g costal defences, geo-engineering tech fixes. Unit 3- Water
conflicts- dams,water transfer schemes,desalination. Energy security-renewable
energy technology. Bridging the development gap-high tech top-down &
intermediate technology bottom-up approach. Superpowers- rich & powerful develop
most new technology- investment in R&D-control access-patents, royalties,licence
fees. Hazard management-monitoring,prediction,relief,reconstruction.
links to wider global issues- global environment crisis- global warming,loss of biodiversity,
water supply degradation, soil erosion. Appropriate technology-affordable & manageable.
Development gap needs to be bridged-improved communications,energy supplies,drugs &
farm technology- improved food security,decreased poverty & reduced vulnerability.
