    Cropping

    Crops grown for agricultural purposes are mostly produced for animal feed.
  • Dairy

    Dairy farms produce milk and milk products that supply both the domestic and the overseas export markets.
  • Agriculture

    The most common agricultural activities in Aotearoa are dairy, cropping, sheep, and beef farming.
  • Bio-oil from wastewater algae

    Research Project
    This project will demonstrate the commercial feasibility of producing bio-oil by the conversion of algae biomass that has been grown in wastewater treatment facilities. In particular we aim to maximise algae production in High Rate Algal Ponds (HRAP) by adding carbon dioxide, and demonstrate energy efficient conversion of algal biomass to bio-oil.

    Has the climate changed in the past?

    The Earth's climate has exhibited marked "natural" climate changes, with time scales varying from many millions of years down to a few years.
  • Fish resources assessment survey of the Arabian Sea coast of Oman

    Research Project
    A primary aim of the Sultanate of Oman Ministry of Fisheries Wealth is to ensure that fisheries are developed and managed for the advantage of the people of Oman in a manner that is sustainable and maintains biodiversity.
  • Remote sensing of phytoplankton biomass and productivity

    Research Project
    Satellite images can be used to measure phytoplankton biomass in the ocean around New Zealand in order to understand ocean ecosystems, fish populations and greenhouse gas absorbtion.
