The Ministry for the Environment and Statistics New Zealand have published a new report on land in New Zealand, Our land 2018.
Summary of the main findings:
- Our soil is affected by erosion and intensive agriculture:
- 192 million tonnes of soil are lost every year from erosion – 44 percent of this is from pasture.
- Soil quality testing shows 2 out of 7 indicators give reason for concern, with 48 percent of tested sites outside the target range for phosphorus content and macroporosity.
- Nearly 83 percent of our native birds, bats, reptiles, and frogs are classified as threatened or at risk of extinction (between 2010 and 2016).
- 20 species of birds improved their conservation status (between 2012 and 2016).
- As well as loss of native vegetation across the country, coastal and lowland habitats continued to reduce.
There have been significant shifts in land use in the last two decades:
- 10 percent increase in the total size of our towns and cities (between 1996 and 2012).
- 42 percent increase in the area of land used for dairy, and a 20 percent decrease in area used for sheep and beef (between 2002 and 2016).
- shift in the past 15 years to higher numbers of animals farmed per hectare, especially in dairy.
- net loss of 71,000 hectares of native land cover (between 1996 and 2012).
- 7 percent decrease in total area of land in agricultural production (between 2002 and 2012)...
