New Zealand’s greenhouse gas emissions by sector and gas 2016
Ministry for the EnvironmentWe measure gases that are added to the atmosphere through human activities. This does not include natural sources such as biological processes or volcanic emissions. We report greenhouse gas (GHG) emissions in carbon dioxide equivalent (CO2-e) units, which is a measure for how much global warming a given type and amount of greenhouse gas causes, using the...Created 8 August 2019 • Updated 8 August 2019 -

Highly erodible land 2012
Ministry for the EnvironmentThe data identifies five classes of land in New Zealand at risk of erosion: high landslide risk – delivery to stream high landslide risk – non-delivery to steam moderate earthflow risk severe earthflow risk gully risk Landslide erosion is the shallow (approximately 1m) and sudden failure of soil slopes during storm rainfall. Earthflow erosion is the slow...Created 8 August 2019 • Updated 8 August 2019 -

Highly erodible land 2012 South Island
Ministry for the EnvironmentThis 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...Created 8 August 2019 • Updated 8 August 2019 -
Growing season soil moisture deficit, 2002-2003
Ministry for the EnvironmentSoil moisture is important for plant growth. A lack of moisture content over a growing season is a good indicator of drought, which can have social, environmental, and economic impacts. Increasing temperatures and changes in rainfall patterns are expected to increase the frequency and intensity of drought in many regions.
