This metadata record describes an image of land predicted to be at risk of severe mass movement erosion for the South Island. The image was produced using the Highly Erodible Land model that identifies land at risk to the main forms of mass-movement soil erosion in New Zealand: landsliding, gullying, or earthflow erosion. If the land has protective woody vegetation, then it is not at risk (Dymond et al., 2006). The Highly Erodible Land model identifies five classes of land at risk of erosion: (1) High landslide risk – delivery to stream; (2) high landslide risk – non-delivery to steam; (3) Moderate earthflow risk; (4) Severe earthflow risk; and (5) Gully risk. Landsliding occurs on steep slopes where the soils do not have protective tree roots. The slope angle at which land is considered at risk to landsliding depends on rock strength. Where land is steeper than this slope threshold and does not have woody vegetation, it is considered at risk to landsliding. There is no slope threshold for land at risk to gullying or earthflow erosion. Where land is at risk to gullying or earthflow erosion and does not have woody vegetation, it is considered at risk. The different types of mass-movement soil erosion are not ranked in severity, except for earthflow risk which has extreme and moderate classes of risk. Use: These data provide a regional perspective on land at risk of soil erosion.

The data identifies five classes of land in New Zealand at risk of erosion:

  1. high landslide risk – delivery to stream
  2. high landslide risk – non-delivery to steam
  3. moderate earthflow risk
  4. severe earthflow risk
  5. gully risk

Landslide erosion is the shallow (approximately 1m) and sudden failure of soil slopes during storm rainfall. Earthflow erosion is the slow downward movement (approximately 1m/year) of wet soil slopes towards waterways. Gully erosion is massive soil erosion that begins at gully heads and expands up hillsides over decadal time scales.

Erosion can have negative consequences on land productivity, water quality (via increased sedimentation and turbidity), the natural form of the land, and infrastructure.

New Zealand experiences high rates of soil erosion. In the North Island, this is mostly due to the historical clearance of forest for agriculture (see also Estimated long-term soil erosion). In contrast, erosion in the South Island is mostly due to natural processes, primarily high rainfall and steep mountain slopes.

It is important to identify areas of land at risk of severe erosion to inform land-use decisions and help prioritise regional soil conservation work.

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 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.

Soil supports the productivity of agriculture, horticulture, and forestry, and filters water to help prevent waterways from becoming contaminated. Different land uses put pressure on the land environment and can change soil quality. Soil quality is assessed under four different groups of land uses: forestry, cropping and horticulture, dairy, and dry stock by measuring the following soil properties: acidity (pH), fertility (Olsen P), organic reserves (total carbon, total nitrogen, mineralisable nitrogen), and physical status (macroporosity and bulk density). Soil scientists have identified the target range for each of these indicators, for maintaining production but with a prime focus for managing risk to the environment.

This measure reports on soil quality, by land use and soil order.

Irrigation is used to support land use, particularly in areas with low or seasonal rainfall. Irrigation can improve the productivity of land for farming activity, and support amenity or recreational land uses within urban environments.Irrigation can also alter the natural character of our landscapes (eg change dry land to greener and wetter land), and can increase nutrient (phosphorus and nitrogen) runoff and leaching into waterways.

Land cover describes the extent of vegetation, water bodies, built environments, and bare natural surfaces (eg gravel and rock) across New Zealand. Measuring the composition of and changes in land cover can help us understand the pressures that different land uses are placing on the biodiversity and functioning of ecosystems.

This measure reports on land cover by class, regional council area, and year.

Livestock farming is a widespread land use in New Zealand and contributes to our economy. High livestock numbers and the distribution of livestock across land environments can affect indigenous biodiversity and soil health (eg compaction). High livestock numbers and density in some land environments can also affect water quality, as nitrogen and bacteria from urine and faeces can leach into groundwater or run off the land into rivers and lakes.

We measure changes in the numbers of farmed livestock (eg beef and dairy cattle, deer, and sheep) across regions in New Zealand.

Dominant land uses in New Zealand include conservation (eg national and forestry parks), forestry (eg for timber resources/wood supply), urban (eg built up areas and open parkland), and agriculture and horticulture. Each land use places different pressures on the land and on receiving environments such as waterways. These pressures can be both positive (eg increased productivity) and negative (eg biodiversity loss and reduced functioning of ecosystems).

This measure reports on agricultural and horticultural land uses by region.
