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

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.

More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.

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.

This dataset measures groundwater quality in New Zealand’s aquifers based on measurements made at monitored lake sites. Many factors influence the quality of our groundwater. Nitrogen, which occurs naturally in groundwater, can increase in concentrations due to agricultural and urban land use, and infrastructure such as waste treatment plants. High concentrations of nitrate-nitrogen in groundwater can affect human health and the quality of surrounding rivers and lakes that receive inflows from groundwater. Ammoniacal nitrogen can cause an undesirable smell that may make groundwater unsuitable for drinking water. Natural processes in groundwater can convert nitrate-nitrogen into ammoniacal nitrogen or other forms under some chemical conditions. Surplus phosphorus drains (leaches) into groundwater as dissolved reactive phosphorus. Too much nitrate-nitrogen, ammoniacal nitrogen, and phosphorus can lead to excessive plant and algae growth where groundwater flows into surface water. E. coli in groundwater is measured in colony forming units (cfu) and can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces. The pathogens can cause illness for anyone who ingests them.
