Geography Assessment Study Notes: Environmental Change & Management and Human Wellbeing

Comprehensive practice vocabulary flashcards covering Topic 1 (Coastal Biophysical Processes and Management at Cronulla), Topic 2 (Human Wellbeing, Development, and Indicators), and Geographical Fieldwork Skills.

Environment

The totality of our surroundings, comprising living and non-living features of the Earth's surface.

Natural environment

Features of the environment that occur naturally and remain unaltered by humans.

Biophysical environment

Features of the environment that are altered or created by people.

Environmental change

Alterations to natural and biophysical environments, encompassing climate change, land degradation, biodiversity loss, and pollution.

Sustainability

Using resources without harming the ability of future generations to meet their needs.

Ecological footprint

A measure of how quickly humans consume resources compared to how quickly the environment can regenerate them and absorb waste.

Human-centred worldview

An environmental worldview that considers humans separate from nature, holding that nature exists primarily to meet human needs with a focus on economic growth and resource extraction.

Stewardship worldview

An environmental worldview asserting that humans have an ethical duty to care for the Earth responsibly, balancing resource use with protection and sustainable management.

Earth-centred worldview

An environmental worldview holding that humans are an integral part of nature, that all species have intrinsic value, and that priority must be given to biodiversity, conservation, and long-term ecological balance.

Sustainable development

Meeting the needs of the present without reducing the ability of future generations to meet their own needs, while improving quality of life and safeguarding the natural environment.

Caring for Country

Indigenous Australians' holistic management of land, sea, and resources rooted in cultural knowledge, spiritual connection, and reciprocal responsibility to Country.

Cultural burning

Cool, low-intensity fire management burns used to clear undergrowth, reduce fuel loads, prevent intense bushfires, and stimulate native plant germination.

Threat abatement

The active control and eradication of invasive species (such as feral cats, foxes, cane toads, and noxious weeds) to safeguard vulnerable native wildlife.

Indigenous Protected Areas (IPAs)

Areas of land and sea managed by Indigenous custodians that comprise over $40\%$ of Australia's National Reserve System.

Constructive waves

Low-energy ocean waves where swash is more powerful than backwash, leading to the net deposition and accumulation of sediment along the coast.

Destructive waves

High-energy ocean waves where backwash is stronger than swash, causing net erosion and stripping sediment away from the beach profile.

Swash

The rush of seawater propelled up the beach face at the angle of the prevailing wind and breaking waves.

Backwash

The movement of water flowing straight down the slope of the beach face back into the sea under the force of gravity.

Longshore drift

The zig-zag transportation of coastal sediment along the shoreline, driven by angled incoming swash and perpendicular backwash.

Primary dune

The outermost frontal dune defined by where vegetation starts inland from the beach, colonised by low-lying, salt-tolerant plants that endure onshore aeolian winds.

Swale

The sheltered trough situated between coastal dune ridges, providing a microclimate where adaptive, reseeding intermediate shrubs flourish away from high winds.

Secondary dune

The mature, stable dune zone situated landward of the swale, where established trees and dense vegetation thrive under the protection of the frontal dune system.

Sand dune

A coastal mound or ridge of loose sediment constructed through aeolian (wind-blown) and hydrospheric transport and deposition processes.

Headland

A high, steep, elevated rocky landform extending outward into the sea between coastal bays or beaches (e.g., Cape Solander at Cronulla).

Reef

A ridge of jagged rock, coral, or sand submerged or partially exposed just below or above the ocean surface (e.g., near Boat Harbour).

Tombolo

A depositional coastal spit or barrier of sand that links an offshore island or rock formation directly to the mainland (e.g., near Greenhills Beach/Wanda).

Clinometer

A fieldwork instrument used in dune profiling alongside a tape measure to quantify slope angles across beach zones.

Anemometer

A weather instrument used in coastal fieldwork to measure wind speed, recording values such as $\sim 8\text{--}10\,\text{km/h}$ at the dune front and $\sim 1\text{--}2\,\text{km/h}$ in the swale.

Sediment replenishment

A soft coastal engineering strategy where sand is dredged or trucked in from outside areas to replenish eroded shorelines and protect natural dunes.

Seabee Wall

A honeycomb concrete seawall erected at Cronulla in 1986 costing $\$1.7\text{ million}$, designed with a curved rim that allows storm waves to dissipate by washing up and over rather than scouring the beach base.

Wave reflection

The bouncing back of incoming wave energy caused by rigid, vertical hard-engineering seawalls, which magnifies backwash strength and strips beach sand out to sea.

Human wellbeing

A good or satisfactory state of human existence characterised by physical and mental health, happiness, social equity, prosperity, and welfare.

Development (NESA)

The progressive process of growing, changing, or advancing into a mature state through economic, social, and political changes that enhance the wellbeing of populations.

Indicator

A sign, measurement, or benchmark that demonstrates the status, condition, or performance of an environmental or social system.

Quantitative indicator

A numerical, statistical measure representing countable quantities (e.g., GDP, GNI, or life expectancy).

Qualitative indicator

A descriptive indicator capturing non-numerical features, subjective feelings, perceptions, and experienced quality of life (e.g., freedom of expression, personal safety).

Poverty (United Nations)

A fundamental condition defined by the UN as 'a denial of choices and opportunities, a violation of human dignity.'

Absolute poverty

A severe state of destitution where an individual or family lacks the bare essential resources necessary for physical human survival, such as nutrition, clean drinking water, and basic shelter.

Relative poverty

A standard of living wherein an individual or household's income falls significantly below the threshold needed to maintain the average or customary living standards of their surrounding society.

Gross Domestic Product (GDP)

The total market valuation of all final goods and commercial services manufactured and delivered strictly within a nation's territorial boundaries.

Gross National Income (GNI)

The total economic yield earned by a nation's domestic citizens and enterprises, calculated as GDP plus overseas investment revenues minus income yielded domestically to overseas residents.

Human Development Index (HDI)

A composite index compiled annually by the UNDP that ranks countries from $0$ to $1$ using combined indicators of life expectancy, educational attainment (literacy and schooling), and gross income.

Australian National Development Index (ANDI)

A holistic, qualitative framework tracking community wellbeing and progress in Australia across twelve core socio-environmental and economic domains.

OECD Better Life Index

A comparative wellbeing tool covering member nations across 11 core dimensions of life, such as housing, employment, community, work-life balance, and civic governance.

Happy Planet Index (HPI)

A metric assessing sustainable wellbeing that ranks nations based on four variables: self-reported wellbeing, life expectancy, inequality of outcomes, and ecological footprint.

World Press Freedom Index

An evaluation assessing media autonomy across 180 countries and territories based on journalistic safety, pluralism, independence, and media law frameworks.

Infant mortality rate

A health benchmark calculated as the total number of infant deaths occurring under one year of age per $1000$ live births.

Life expectancy

The statistical projection of the average number of years a newborn infant can be expected to survive based on prevailing demographic mortality conditions.

Sustainable Development Index (SDI)

An indicator designed to measure the ecological efficiency of human development, calculating development milestones attained relative to strict planetary boundaries.
