Environmental » Healthy Environment

We have clean water, fresh air and healthy soils. Well-functioning and diverse ecosystems make up an environment that can support our needs. Resources are used efficiently. There is minimal waste and pollution.

What is Healthy Environment?

Good air, water and soil quality, and reducing waste are all essential to maintaining a healthy environment and ensuring the sustainability of resources. Water-based recreational activities are part of an outdoor-focused way of life and it is essential that the water is of a high quality. Protecting land through open space covenants also helps maintain ecosystem diversity, along with natural and cultural heritage. Primary land uses such as agriculture, dairying and cropping are key contributors to an economy but they can have a negative influence on the environment. 

16 indicators are used to measure progress towards the healthy environment outcome (defined above). Data relating to each individual indicator (for the 2001 to 2016 period) is provided via the menu below. The healthy environment index (pictured below) shows the composite average of the individual indicators.

As there is only one community outcome under environmental well-being, the same index is applied to both the well-being aspect and the community outcome area.

Healthy environment, 2001-2016

What this means

The healthy environment index increased between 2001 and 2016 by 8.1%.

 

The index exhibits some fluctuations, exacerbated by indicators such as stream and river health, landfill waste and GHG emissions per capita that, whilst demonstrating improvement when viewed across the entire time series, experienced sharp declines in some years, and notable increases in others.

 

Key improvements relate to the suitability of marine and freshwater sites for recreation, and the per capita water supply (a measure of sustainable water consumption). Two indicators that have not shown signs of improvement however are soil quality of dairy farm sites and perception of air pollution as a problem.

Did you know?

A GPI is an attempt to measure whether a nation’s or a region's growth, increased production of goods, and expanding services have actually resulted in the improvement of the well-being of the people in the region.

Stream and river health

Why is this indicator important?

Macroinvertebrates are good indicators of the life-supporting capacity of streams and rivers as well as the ecological health of a stream or river. The condition of stream and river systems also represents an integration of land use activities. Stream and river health is therefore an effective indicator of wider catchment health and the sustainability of land uses. Safeguarding freshwater systems is essential to providing for human uses and protecting biodiversity.

Stream and river health, 2005-2016

Findings

  • In 2016, 62% of monitored sites had a macroinvertebrate community index (MCI) classification of good or excellent.
  • The majority of sites in the excellent MCI class are located in catchments dominated by indigenous forest cover.
  • The percentage of sites with an MCI of good or excellent has fluctuated over the monitoring period, with the percentage in 2015 & 2016 below results recorded in 2014.
