This dataset was first added to MfE Data Service on 16 Apr 2019.

This indicator measures the concentrations of four heavy metals (lead, copper, zinc and cadmium) against the Australian & New Zealand Environment and Conservation Council (ANZECC) guideline values for toxic substances in estuarine sediment.

Heavy metals occur naturally in estuaries, but high concentrations suggest contamination from another source. The metals can be transported along waterways from urban environments (and, for cadmium, from farmland) and accumulate in estuarine and coastal sediments. Heavy metals are toxic although some such as copper and zinc are classed as micro-nutrients at very low concentrations. They accumulate in sediment, where they can be taken up by organisms, and are harmful to species and habitats. They also bio-accumulate (are found in higher concentrations in species further up the food chain).

This data measures the numbers of farmed livestock (dairy and beef cattle, deer, and sheep) over time across New Zealand.

Livestock farming is a widespread land use in New Zealand and is a large contributor to our economy. High livestock numbers and the distribution of livestock across land environments can affect indigenous biodiversity and soil health (eg through erosion, habitat loss, compaction, and nutrient concentration). Water quality can also be adversely affected, as nutrients, sediment, and bacteria from urine and faeces can leach or run off the land into rivers, lakes, and groundwaters. This can affect the health of the aquatic ecosystem, as well as recreation and cultural values associated with rivers and lakes.

This dataset was first added to MfE Data Service on 16 Apr 2019.

This dataset shows the total irrigated agricultural land area across New Zealand for 2002 and 2017. Agricultural land irrigated in 2017 is broken down by types of irrigation systems and farm type.

Although it enables and improves farming, irrigation can also have adverse consequences relating to recreation, and can increase pollution and leaching of contaminants into waterways. Irrigation can affect the natural form and character of land (eg dry land to greener and wetter land), fishing, cultivation and food production, animal drinking water, water supply, commercial and industrial water use, and hydro-electric power generation. More irrigated land, and more water abstraction, can place increased pressure on river flows, as well as indirectly increasing pressure on land and fresh water by enabling increased agricultural intensity.
