Zusammenfassung der Ressource
Technology for all?
- To use technology and changes in attitude to reduce resource consumption and pollution to more sustainable levels. This is necessary to avoid an environmental crisis
- To use technology and resources to develop parts of the world where poverty, ill-health, illiteracy and food insecurity are growing concerns. This is necessary to avoid a humanitarian crisis
- A green revolution for Africa?
- The Alliance for a Green Revolution in Africa (AGRA), an organisation funded by the Gates
Foundation ($150 million) and the Rockefeller Foundation ($50 million), is one body seeking solutions.
- The need is critical, as Africa's population growth rate of 3% per annum
since the 1960s has exceeded its agricultural production growth rate of 2%
- Low levels of agricultural investment mean that maize yields in Africa are typically 1-1.5 tonnes per hectare, compared to 2.5-4.5 in field trials where the best available technology is used
- There have been some successes, such as the rice variety Nerica, which has a short growing cycle, resists weeds and doubles yields
- The green revolution of the 1960s and 1970s bypassed Africa, so now agricultural research is looking for a way to bring such a change to this continent
- More than the right
seeds are required:
- Water for irrigation
will be required
- Fertilisers will be needed, but if new crops require large quantities, input costs will spiral
- Improved storage of crops is required to prevent rot and rodent damage, so that surpluses can be stored until sale
- Access to markets require better roads, as well as communication systems to check prices. Farmers who cannot get their surplus production to market will be no better off
- Education is needed in crop management, pest control, water management and the impact of climate change
- Current research is focused on developing
drought-resistant crops, such as maize and
cassava, capable of tolerating Africa's
variable and infrequent rainfall
- Much more investment is needed if a Green Revolution
is to spread to Africa's 180 million small famers
- Business as usual
- Our current model of technological development, with its dependence on
fossil fuels, seems incapable of meeting either of these challenges
- A business as usual approach is likely to lead to further increases in
greenhouse gas emissions, land degradation and water shortages
- Global inequality is likely to continue to grow, leaving many parts of
the world, such as sub-Saharan Africa, technologically impoverished
- Bangladesh
- Poor countries such as Bangladesh face stark choices and limited options in the future
- Some 10 million Bangladeshis live on land less than 1 metre above sea level
- If sea levels rise this far, 15% of the country could be lost
- In many areas, groundwater has already turned salty, forcing farmers to switch from growing rice to the aquaculture of shrimps and prawns
- Bangladesh's 130 million people produced 0.1% of global greenhouse gas emissions in 2004, opposed to 22.2% produced by the USA's 300 million people
- Can technology come to Bangladesh's aid?
- Sea level might be slowed or halted if the developed world used technology to reduce carbon emissions
- Coastal populations might be relocated inland, but farm technology would be needed to boost yields and feed the people
- Sea defences could be constructed, but the estimated cost runs to billions of dollars, well beyond Bangladesh's means
- Flood warning technology and cyclone shelters and flood platforms would save lives, but not crops
- Aid might be required more frequently in the future if tropical cyclones and river flooding become more common
- A country like Bangladesh can only
realistically use technology to cope with
frequent flood disasters that afflict it.
- Longer term solutions that prevent disaster are out of its hands without either
massive aid from the developed world or action to tackle global warming
- Technological convergence
- Of all the technologies invented in modern times, the one which
people have come to depend on most is probably the internal
combustion engine, developed in the 1870s and 1880s
- When Karl Benz used this engine to
power the first automobile in 1985,
our love affair with the car began
- More than 120 years later there are around 700 million vehicles globally, most of the private cars
- Cars allow individual mobility, creating choice and allowing people to live and work where they wish
- The spread of the motor vehicle is an example of technological convergence
- Road transport plays a key role in development, allowing markets and networks to operate
- Transport is an industry, typically accounting for 5-10% of GNP and providing jobs and income growth
- As a country develops, people seek to buy cars both
as a status symbol and to increase their mobility
- The launch of the Indian-built Tata Nano in 2008, priced at $2,500 (the world's cheapest car) shows how keen developing nations are to get mobile
- More cars however means more carbon dioxide
emissions and a higher risk of serious climate change
- In China the rapidly expanding economy
has led to a soaring demand for cars
- Sales grew by 56% in 2002 and 75% in 2003
- China's 22 million private cars in 2007 were expected to grow to 140 million by 2020
- Energy efficiency
- Globally, 12% of greenhouse gas emissions come from transport, and this is likely to rise as car numbers grow
- Adoption of automobile technology by the BRIC economies has serious environmental implications
- Forcing people not to buy cars is politically unrealistic
- The price of fuel may reduce demand, but in many developing countries fuel is subsided
- Launched in 2007, the Automotive X-Prize is a
global competition to find a 100mpg four
passenger car. The winner will receive $7.5 million
in prize money from the X-Prize Foundation
- This non-profit foundation is well known for its
competitive challenges which seek to encourage
technological breakthroughs
- Already a German company, Loremo AG, has demonstrated a car with fuel efficiency well in excess of 100mpg
- If widely adopted, cars such as the Loremo could have a dramatic impact on greenhouse gas emissions
- The Loremo is planned to sell for only €15,000, so perhaps here is a case of energy efficiency not costing the earth
- Other automobile technologies may help reduce the environmental impact of the car, but they need further development
- Electric Cars
- Electric cars could reduce emissions if they use renewable sources of electricity
- Conventional batteries are heavy and lightweight lithium-ion battieries are expensive
- Only a limited distance can be covered at present by a single charge of the batteries
- Hydrogen Cars
- Either burning hydrogen or using a hydrogen fuel cell
to produce electricity, would only emit water vapour
- Producing hydrogen is energy-intensive, so
renewable energy would be needed to do this
- There are also major safety challenges in transporting
hydrogen and refuelling because it is highly flammable
- Biofuels
- In theory is close to carbon-neutral, but
there are concerns about using land to
grow plants for fuel instead of fuel
- Technology Transfer
- In 2007, a report by the IMF, 'Technology Widening Rich-Poor Gap',
concluded that the world has become increasingly unequal since 1980
- It stated that technology has contributed most to this rising inequality and technological divergence
- The IMF study suggested this was because of
- Rising levels of technology require a workforce
with skills and education that the poorest lack
- Manufacturing plants in Asia have trained
a skilled workforce, allowing them to
benefit much more than unskilled workers
in Africa and Latin America
- The report concluded that education was the
key to ensuring people in the least developed
parts of the world could benefit from new
technology
- In order to prevent the technology gap
widening even further, significant technology
transfer to the developing world is required
- The commitment to development technology
index, produced by the Centre for Global
Development, measures the developed world's
willingness to allow this technology transfer.
- Countries with
high index scores,
such as France,
are characterised
as:
- Refusing to grant patents for new plant and animal varieties,
as these could deprive poor countries of new food crops
- Refusing to allow patents on some ICT software innovations that the developing world could use
- Not using bilateral aid as a lever to extend intellectual property rights
- Forcing patent holders to license production of innovations that are seen as being for the public good
- If the developed world wants the developing world to adopt technologies that might help solve
global environmental problems, these have to be available at low cost
- Such technology transfers do happen, but they
often rely on NGOs to provide the funding
required to purchase and install the technology
- In many cases, this might be achieved by waiving patent and intellectual property rights in
some countries in order to allow low-cost production to begin
- Solar power is one such technology. If used
extensively in the developing world, it will need to
cost less than power from fossil fuels
- Practical Action is a UK NGO which has installed 6,000 solar powered
water pumps across the developing world, at a cost of around $6,000 each
- Solar water pumps
are designed to:
- Provide 40 litres of water per person per day
- Provide water for people, livestock or crops, and therefore improve health and food security
- Store 3-5 days supply of water as a
buffer against cloudy periods
- The Future
- The contested planet's environmental problems are
partly a result of our addiction to technology,
particularly those technologies powered by fossil fuels
- The widening development gap is to
some extent caused by the different
levels of access to technology that
different groups experience
- Technology has a role to play in narrowing the development gap
and addressing the key global concerns such as global warming
- This will only happen if we develop environmentally
sustainable technologies and make them available to all
- We have to face difficult technological, economic and moral choices if we are to successfully
reconcile the urgent need for global environmental sustainability and human development
