Flashcards
common goods : 2 characteristics
- non excludability: can be used freely by anyone
- rivarly in consumption: use by one perosn affects use by the other
tragedy of the commons
risk of overexploitation because individuals have incentive to take more than is socially desirable
Hardin's approach to commons
- freedom in commons brings ruin to all
- solutions
- government regulation
- provatization
Ostrom's approach to commons
- tragedies of commons are real but not inevitable
- communities can self organize
4 prerequisites to institutional effectiveness (Ostrom)
- user interest in collaborative sustainable use of commons
- shared undertanding of resource system
- monitoring of commons and compliance to rules
- expected profits > transaction costs
elements leading to raise awareness of environmental problems
- oil crisis
- limits to growth (club of rome)
- industrial accidents
- political awareness
club of Rome
examined trends
- examined trends
- global pop
- industrialization
- pollution
- food production
- resource depletion
club of rome
assumptions
- exponential growth of population and pollution
- linear growth of technology to increase available resources
club of rome results
absolute limits to earth will be reached in 100y (from 1972)
Brutland definition of sustainable development
development that meets the needs of the present without compromising the future generations to meet their needs
limits to meet needs imposed by technology and social organization
3 parts of brutland definition
- Meeting needs in long term, inter-generational justice
- intragenerational justice (north-south conflict)
- protection of nature to serve humans
critiques of Brutland definition
- lack of contour of concept and content
- compromise between 2 antagonistic interests
- developing countries catching up
- industrialized countries limiting growth
rio summit
1992, follow up Brutland def
- 27 principles to guide for SD
- Agena 21
3 pillar model
- Sustainability = balance btw environment, society and economy
- pro: imbalance recognized as unsustainability
- con: difficult to operationalize
questions of philosophical approach to Brutland
- equal disribution of needs or performance?
- Other moral values than (distributional) justice?
- how to compare well being btw generations?
John Rawl's theory of justice
- justice as fairness includes
- liberty principle
- fair equality of opportunity
- difference principle
difference principle: 3 elements
- each person has equal right to liberty compatible w others'
- social and ecc inequalities must
- benefit the least advantaged
- be open to all (fair equality of opportunity)
- principle of justice chosen by parties in original position (veil of ignorance)
advantages and questions to Rawl's approach
- pros
- considers fair distribution and freedom (various moral values)
- addresses intergenerational justice and time
- addresses 2 categories of fair distribution (needs and performance)
- question: operationalization of difference principle?
Routes towards sustainability
- scientific route
- economic
- natural science
- ecological-economic
- ethical route
scientific route
- sustainability = preservation
- described as observable property of a system
economic route
- Sust = ability of future generations to produce, consume and meet their needs
- Robert Solow: replace used-up resources by non-renewable ones to preserve productivity
natural science route
- sustainability = applied to natural systems to research on
- basis of human life
- conditions for its maintenance
- Ex. planetary boundaries
ecological-economic route
- sustainability as vector of development that doesn't increase over time
- ex SGDs
2 open questions to scientific route
- defining sustainability
- what system should be preserved
- for how long
- when is it preserved
- operationalizing sustainability: how to preserve it
3 problems w scientific route
- non-knowledge, uncertainty and complexity of environment and economy
- agreement: ppl must accept knowledge and agree on measures
- implementation: measures must be obeyed and monitored
ethical route to sustainability
def and effectiveness (3)
- sust = justice and responsibility
- guidance and ideal on how to act fairly
- effectiveness:
- changes human norms
- voluntary setting and obeying rules
- no planned or forced development, no guarantee of result
3 steps to operationalize sustainabiltiy
- translate abstract concept in empirically testable sustainabilty target
- measure degree of achievement by indicators
- formulate management rules (normative)
environemental standard
def, 3 steps, 2 examples
- define legal concepts by operationalizing and standardizing measurable values in proscriptions, preecets and permissions
- describe status by indicators and set targets
- deficit analysis: compare status quo and target
- derive need for action
- example EU water framework directive
- example SGDs
achievements of WFD and critiques
- achievements
- effects on water management
- status is measurable and testable (deviation from untouched water)
- progress
- critiques
- no guidance for use conflicts
- no intersectoral coordination
achievements and critiques of SDGs
- achievements
- overview in many sust fields
- monitoring and targets
- sets political goals
- critiques
- weak data basis
- non-binding
- limited impact
common aspects to all sustainability approaches
- intra and inter generational justice
- long run perspective
- comprehensiveness (holistic approach)
- preservation of nature
shortcomings of sustainabiltiy concepts
- dealing w uncertainty
- integrating soft knowledge
- grasp long term effects
- meet holistic perspective
- normative aspects
our 5 bequests
- economy
- nature
- cultural heritage
- institutions
- waste
fair bequest def
renewable and non renewable resources
- a fair bequest is to sustain man-made and natural capital, that should not decline over time
- renewable resource: harvest rate < growth rate
- non renewable resource: cake eating model, see Hartwick
2 economic approaches to define sustainability
- consequentialistic: oriented towards consumption
- opportunity-oriented: preserving resources and capital
capital, definition
- Real capital is
- a production factor
- man made
- durable (not consumed but wears off)
- renders services
Hartwick's rule
if the gains from selling a non-renewable resource are not consumed but invested into capital, the productive capacity of the economy is sustained
result = constant stream of consumption
Hartwick's assumptions
- constant population size
- capital does not wear off
- good produced w capital and non renewable resource
- output can be used for consumption or investment
investment rule
re-invest the profit from selling a non-renewable resource (revenue - extraction costs) into building capital stock
results in constant stream of consumption -> non renewable resource can be used in sustained manner
limits to Hartwick's rule
- no depletion rate
- constant population
- substitution (Cobb-Douglas production function)
- resources and capital are essential (>0)
- but resource can be small
- = weak sustainability: assumes sustainability of natural capital through man made capital
