3rd lecture The goals of environmental policy Flashcards
Malthusianism
Thomas Robert Malthus (1766-1834)
An Essay on the Principle of Population
Human population grows exponentially, food supply arithmetically
Poverty is the result of natural laws, thus inevitable
Problems with Malthusianism
Food supply has risen exponentially
Distribution of resources was more effective
Meadows: Limits to growth
Five trends were studied:
The accelerating rythm of industrialisation,
Rapid Population Growth
Widespread malnutrition
Depletion of non-renewable resources
Deteriorating environment
Meadows: Limits to growth Conclusions:
Without any change in the trends, the world would definitely collapse sometime before 2100
The most probable result would be a rather sudden and uncontrollable decline in both population and industrial capacity
Solution: steady-state world, redistribution of resources
Problems with „Limits to growth”
Too pessimistic about technological advances
Too few variables, oversimplification
Different types of economic growth: energy intensive growth versus environmentally benign growth (road transportation versus well-managed forestry)
Gro Harlem Brundtland: Our Common Future
Current global trends cannot be sustained in the long run becuase they destroy the environment and are unjust
The notion of sustainable development: „is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs”
Equity:
fairness in the distribution of environmental services within and between generations
Assessing sustainability – three key criteria
Equity: What will be the impact on the distribution of wealth and other factors affecting the quality of life?
Futurity: Impact on medium and long term?
Value of environment: Proposals that treat environmental services as though they were free violate this criteria
Assessing sustainability – the capital approach
One generation should bequeath to its descendants at least as much capital as it is inherited from its immediate ancestors
Weak sustainability: environmental capital and economic capital is substitutable. We should only care about the amount of capital.
Strong sustainability: environmental and economic capital is not substitutable, there is no reverse action. We should protect every form of environmental capital!
Different types of environmental capital
Critical environmental capital:
Attributes of the environment which are of the greatest importance or rare but highly valued
Constant environmental capital:
Constant assets are not yet scarce, but could become so if not managed carefully
Tradable environmental capital:
Either such assets are not in danger of becoming scarce, or the environmental services are not highly valued, or could be easily compensated
