Weak and Strong Sustainability
نویسنده
چکیده
Sustainable development requires economic development without endangering biodiversity, without exploiting natural resources too fast and without excessive pollution. The question is if these aims can be realized at the same time and what are the options for substitution between different types of capital. The difference between the notions of weak and strong sustainability revolves around the issue of substitutability, from a technical/physical point of view, as well as from ethical considerations. In this contribution, an overview is given of the relevant aspects in this matter. Attention is paid to standard theories of economic growth, including natural resources and the substitutability between natural resources and human-engineered capital. Also pollution is taken into account. In addition to the growth model with exogenous technical progress, also endogenous growth theory and its linkage to the sustainability debate is considered.

Appraising Weak and Strong Sustainability: Searching for a Middle Ground
This paper seeks to address the issue of weak and strong sustainability as well as the search for a middle ground. It discusses the differences between weak and strong sustainability while arguing for the harmonisation of both nature and humankind. Achieving harmony requires a move towards an idealist eco-sociofeminist point of view. Through this, full equality and balance may be attained.

Sustainability is defined in terms of four overlapping positions, ranging from very weak to very strong sustainability. The core idea is of a non-declining capital stock (including natural capital) over generational time. Weak sustainability positions emphasise capital substitution possibilities and the power of technical process to mitigate resource depletion and pollution problems. Climate ch...
متن کاملUnsustainable development pathways caused by tropical deforestation
Global sustainability strategies require assessing whether countries' development trajectories are sustainable over time. However, sustainability assessments are limited because losses of natural capital and its ecosystem services through deforestation have not been comprehensively incorporated into national accounts. We update the national accounts of 80 nations that underwent tropical defores...

While there is a universal recognition that sustainability includes social, economic, and environmental components, the relationship and interchangeability between these components has been debated, resulting in three distinct sustainability perspectives: weak, strong, and absurdly strong sustainability. However, despite this active debate, few h...

We analyze the e¤ects of rarity value on the economic and ecological sustainability of a natural resource. Rarity value means that under extreme scarcity of the resource unit pro ts increase explosively. We focus on equilibrium behavior of very patient agents in a Small Fish War. In such a setting, agents interacting on a body of water have two options: they can sh with restraint or without....
