Sustainability

Meeting people's present needs in a way that does not stop future generations from meeting theirs. It balances environmental limits with social fairness and economic activity over the long term.

Related: Intergenerational equity, Sustainable development, Triple bottom line
Sustainable development

Development that improves people's wellbeing while protecting the natural systems it depends on. It aims to raise living standards without using up resources or causing damage that future generations inherit.

Related: Sustainability, Intergenerational equity, Carrying capacity
Intergenerational equity

The idea that people living now should not use resources or cause harm in ways that leave later generations worse off. It asks whether today's choices keep options open for the future.

Related: Sustainability, Futures thinking
Carrying capacity

The maximum number of people or level of activity an environment can support without being degraded over time. Exceeding it leads to resource depletion, pollution, or ecosystem decline.

Related: Ecological footprint, Resource depletion, Limits to growth
Ecological footprint

A measure of the land and water area needed to supply a person's or group's resources and absorb their waste. It is compared with available area to show whether demand exceeds what the planet can regenerate.

Related: Carrying capacity, Resource depletion
Triple bottom line

A way of judging success by three results at once: environmental health, social wellbeing, and economic viability. A decision is only truly sustainable when all three are acceptable, not just profit.

Related: Sustainability, Systems thinking, Trade-off
Interdependence

The way parts of a system rely on each other, so a change in one part affects the others. Environmental, social, cultural, and economic factors constantly influence one another.

Related: Systems thinking, Feedback loop, Trade-off
Systems thinking

Looking at a problem as a set of connected parts rather than isolated pieces. It traces how causes, effects, and delays ripple through a whole system, including unexpected side effects.

Related: Interdependence, Feedback loop, Leverage point
Feedback loop

A cycle where a change produces an effect that feeds back to increase or reduce the original change. Reinforcing loops amplify change; balancing loops resist it and push a system toward stability.

Related: Systems thinking, Tipping point
Trade-off

Accepting a disadvantage in one area to gain an advantage in another. Sustainability decisions often involve trade-offs between economic gain, environmental protection, and social fairness.

Related: Triple bottom line, Interdependence
Externalities

Costs or benefits of an activity that fall on people or environments not involved in the transaction. Pollution from a factory is a negative externality because others bear the harm.

Related: Trade-off, Ecosystem services
Ecosystem services

The benefits nature provides to people, such as clean water, pollination, flood control, and food. Their loss is often invisible in markets but costly to society and the economy.

Related: Externalities, Biodiversity, Natural capital
Natural capital

The stock of natural resources and living systems that produce value, such as forests, soil, water, and minerals. Using it faster than it regenerates reduces the capital available for the future.

Related: Ecosystem services, Resource depletion
Resource depletion

The using up of a natural resource faster than it can be replaced or renewed. It can be local, such as overfished waters, or global, such as declining fossil fuel reserves.

Related: Carrying capacity, Natural capital
Biodiversity

The variety of living things in a place, from genes to species to whole ecosystems. High biodiversity helps systems stay resilient to change and supports human food and medicine.

Related: Ecosystem services, Resilience, Tipping point
Resilience

The ability of a system, community, or ecosystem to absorb shocks and recover without collapsing. Diverse, flexible systems usually cope better with disturbance than narrow, rigid ones.

Related: Biodiversity, Adaptation, Carrying capacity
Tipping point

The threshold where a small extra change pushes a system into a very different state that is hard to reverse. Examples include a fishery collapsing or a reef bleaching permanently.

Related: Feedback loop, Resilience
Limits to growth

The idea that endless increases in population and consumption cannot continue on a finite planet. Growth eventually meets resource limits, pollution limits, or both.

Related: Carrying capacity, Resource depletion
Mātauranga Māori

The body of knowledge held and developed by Māori, passed down through generations and grounded in relationships between people and the environment. It includes science, values, and practice specific to place.

Related: Kaitiakitanga, Mauri, Whakapapa
Kaitiakitanga

The Māori responsibility to guard and care for the environment and people on behalf of past and future generations. It is an active duty of stewardship, not simply protection or non-use.

Related: Mātauranga Māori, Mauri, Intergenerational equity
Mauri

A Māori concept describing the life force or vital essence present in people, places, water, and living things. Actions that damage mauri are seen as harming the wellbeing of the whole system.

Related: Mātauranga Māori, Kaitiakitanga
Whakapapa

A Māori framework of connections and genealogy that links people to ancestors, land, and other living things. It frames humans as part of nature rather than separate from or above it.

Related: Mātauranga Māori, Interdependence
Tangata whenua

Māori who hold ancestral and customary authority over a particular area of land or water. Their role as local guardians shapes how sustainability decisions are made in that place.

Related: Kaitiakitanga, Mātauranga Māori
Te Ao Māori

The Māori worldview, which sees people, land, water, and spiritual forces as interconnected. It emphasises collective relationships and long-term responsibilities rather than individual gain.

Related: Mātauranga Māori, Whakapapa
Worldview

The set of beliefs and assumptions a person or culture uses to understand how the world works. Different worldviews lead to different views on what counts as a sustainability problem.

Related: Te Ao Māori, Values
Values

The principles and priorities people consider important, which guide what they see as right or desirable. Sustainability conflicts often arise because groups hold different values, not just different facts.

Related: Worldview, Trade-off
Environmental justice

The principle that no group should carry an unfair share of environmental harm, such as pollution or lost access to resources. It links environmental issues to fairness and power.

Related: Social equity, Externalities
Social equity

Fairness in how benefits and burdens are shared across a community, including income, health, and access to resources. Sustainability requires that improvements do not deepen inequality.

Related: Environmental justice, Triple bottom line
Sustainability issue

A specific problem where current human activity threatens environmental, social, cultural, or economic wellbeing. It usually has multiple causes and affects several groups in different ways.

Related: Cause and effect, Stakeholder
Cause and effect

The link between what creates a problem and the results that follow. Mapping direct and underlying causes helps explain why a sustainability issue persists and where to intervene.

Related: Root cause, Leverage point
Root cause

The underlying reason a problem exists, rather than its visible symptom. Addressing a root cause usually changes a system more durably than treating symptoms.

Related: Cause and effect, Leverage point
Stakeholder

Any person or group affected by, or able to influence, a decision or issue. Identifying stakeholders and their interests reveals whose views are included or left out.

Related: Values, Consultation
Consultation

Seeking and considering the views of affected people before making a decision. Good consultation is genuine, timely, and shapes the outcome rather than confirming a plan already fixed.

Related: Stakeholder, Tangata whenua
Leverage point

A place in a system where a small, well-targeted action produces a large and lasting change. Finding leverage points is more effective than pushing harder on symptoms.

Related: Systems thinking, Root cause
Action plan

A written outline of what will be done, by whom, by when, and how success will be measured. It turns a sustainability goal into concrete, checkable steps.

Related: Indicator, Monitoring
Indicator

A measurable sign used to judge whether a condition or action is improving, worsening, or unchanged. Good indicators are specific, relevant, and possible to collect reliably.

Related: Monitoring, Action plan
Monitoring

Repeatedly checking chosen indicators over time to see whether an action is working. It allows adjustments when results differ from what was expected.

Related: Indicator, Evaluation
Evaluation

Judging the value and outcomes of an action against its aims, using evidence. It considers what worked, what did not, and what should change next time.

Related: Monitoring, Indicator
Futures thinking

Exploring possible, probable, and preferred futures to make better decisions now. It uses scenarios and long timeframes to reveal risks and opportunities that short-term thinking hides.

Related: Scenario, Intergenerational equity, Precautionary principle
Scenario

A plausible story of how the future could unfold, built from different assumptions and trends. Comparing scenarios helps people see trade-offs and choose actions that are robust across them.

Related: Futures thinking, Adaptation
Precautionary principle

The idea that where serious harm is possible but not yet certain, action to prevent it is justified. It shifts the burden of proof toward showing that an activity is safe.

Related: Futures thinking, Tipping point
Adaptation

Adjusting practices, infrastructure, or behaviour to cope with changing conditions and reduce harm. It differs from mitigation, which tackles the cause of the change itself.

Related: Resilience, Mitigation
Mitigation

Acting to reduce the causes or severity of a problem, such as cutting emissions or restoring habitat. It contrasts with adaptation, which responds to effects already occurring.

Related: Adaptation, Precautionary principle
Sustainable decision-making

Choosing between options by weighing environmental, social, cultural, and economic effects over short and long terms. It includes uncertainty, affected groups, and future generations in the reasoning.
