AOS2 Is development sustainable ?
sustainability
ecological sustainability
using conserving and enhancing resources so that ecological processes and quality of life can be maintained
ESD
development that meets present needs without compromising that of future generations
"needs"
needs of the worlds poor (to which priority should be given)
"limitations"
imposed by the state of technology and social organisation of the environment
challenges to ESD
cost
commercial and industrial group returns, profits, shareholders, owners
stakeholders
people, groups, organisations that have interest in/ might be affected by actions or policies
values
principles, standards, qualities they hold in high regard
affects how they evaluate situations
knowledge
scientific, technical, experiential
population (enough for EVERYONE and enough for ECOSYSTEM)
clean water
use less, produce less waste, reuse more
meeting present needs without compromising that of the future
3 spheres
environmental
natural resource use, environmental management, pollution prevention
social
standards of living, education, community, equal opportunity
economic
profit, economic growth, cost savings, research + development
can interconnect
main issues for long term sustainability
1- population growth
2- energy availability
3- water availability
4- food availability
circular economy
reduce environmental impacts of production + consumption
more productive use of natural resources (and resource use is minimised)
waste and pollution are minimised/ avoided through design and efficient practices
environmental impacts reduces while maintaining/ increasing value of goods and services
design is conscious of durability repair reuse and recycling
maintenance repair and disposal
innovations are to increase resource productivity, bring jobs, economic growth
product life is MAXIMISED with repair and reuse, then recycled and refabricated
sustainability principles
intergenerational equity
between generations
how will future generations be affected
provides for the current generation with no compromise to the needs of the future generations
employment, resources, future effects on climate change/ environment, preserving an area
intragenerational equity
preserving natural resources for all among the current generation
how is the scenario affecting the different groups in the current generation
fairness in treatment, non-discrimination
human rights
working jobs with health risks out of necessity
precautionary principle
the people carrying out the activity are required to prove that their actions wont cause serious/irreversible damage to the environment
risk assessments, EES as evidence
environmental risks held at high important
conservation of biodiversity and ecological integrity
conserving an area/ region, the diversity of its species and processes
ecosystems and species being preserved
are areas being fragmented, are populations being isolated ?
reduction in pollution, climate change
maintain natural processes
efficiency of resource use
using smaller amounts of physical resources to provide the same product or service while minimising environmental impact
renewable energy
energy efficient equipment + materials
waste minimisation
reduce cost, promote efficiency
user pays
calls upon user of a service or resource to pay directly for the amount they use rather than cost being shared by all users or the community
eg tilt renewables paying for the construction instead of nearby communities
SAC 2 case study
flow of wind energy
wind spins turbine
turbine spins rotor attached to generator
generator creates electricity
travels to transformer where voltage is changed to the right level
then goes to substation where electricity is distributed
then it is stored in the energy grid and can be transported to homes
