Sustainability Concepts and Perspectives
What this domain tests
This section of the Level 2 Education for Sustainability course asks you to define sustainability precisely, distinguish it from related ideas, and apply different perspectives to a real decision. Examiners reward accurate concepts used as tools, not slogans.
Core concepts
Sustainability is the capacity of social, environmental, cultural, and economic systems to endure and regenerate. Sustainable development, from the 1987 Brundtland Report, is development that meets present needs without compromising future generations' ability to meet theirs. That definition contains two equities: intragenerational (fairness now) and intergenerational (fairness over time). The four dimensions are interdependent: environmental (ecosystems, resources), social (wellbeing, equity, participation), cultural (identity, values, practices), and economic (livelihoods, costs, markets). Weak sustainability assumes human-made capital can substitute for natural capital; strong sustainability treats critical natural capital as non-substitutable. The precautionary principle says uncertainty is not a reason to postpone cost-effective action against serious harm. Perspectives include anthropocentric, ecocentric, technocentric, and Indigenous relational views such as kaitiakitanga.
Worked example
A council proposes discharging treated wastewater into a river. A weak answer says it is bad for the environment. A stronger answer names the dimensions: environmental (nutrients, habitat), social (swimming, health), cultural (mahinga kai, mauri), and economic (treatment cost, tourism). It applies intergenerational equity by asking about cumulative effects over 30 years, and the precautionary principle because effects are uncertain. Strong sustainability would reject trading the river's mauri for a cash payment. A reasoned conclusion might be conditional consent with nutrient limits and monitoring.
Traps that cost marks
Reducing sustainability to eco-friendly; confusing sustainability with sustainable development; ignoring who bears costs; treating cultures as stereotypes; using a perspective without explaining what it reveals.
