Native forests – barriers and enablers

Manaaki Whenua – Landcare Research

$159,400

Combining a desktop review of data, both held by Manaaki Whenua and publicly available, with an additional survey to quantify landowner intentions, barriers, and drivers in afforesting and regenerating native forest.

Improving Organic Soil emissions accounting

Manaaki Whenua – Landcare Research

$206,000

Providing a pathway for implementation of the IPCC 2013 Wetland Supplement methodology by reviewing existing information, recommending specific emission factors, and recommending priority areas for future research.

Improved data on harvested wood products

University of Canterbury

$120,000

Identify the end-use products, half-life values, and the associated uncertainty values for harvested wood products made from roundwood logs harvested and processed in New Zealand, so that wood product carbon stock estimates are based on country specific values.

Information on dairy farming systems

Dairy New Zealand

$80,000

Estimate the number of dairy cattle in different farm systems and the likely timing and differences in diets between 1990 and present.

Sheep and cattle birth and slaughter dates

AgResearch

$100,000

Reviewing the birth and slaughter dates for NZ sheep and beef cattle, and evaluate the suitability of current assumptions for these in the New Zealand inventory model.

Methane from supplemented dairy cows

AgResearch

$955,300

Determine CH4 emissions from early-mid lactation dairy cows grazing pasture and supplemented with graded levels of concentrate. New data will be combined with relevant existing data from New Zealand and international databases on methane emissions from dairy cows to determine if CH4 emissions differ between cattle fed pasture alone or with concentrate supplementation.

Quantifying N2O emissions from eutrophic lakes

Massey

$81,341

This project will attempt to map potential emissions of N2O from eutrophic lakes, and will investigate two aquatic ecosystems over one year.

The impact of pasture Kikuyu content on enteric methane emissions

AgResearch

$62,000

Assess the composition and methane yield potential of Kikuyu based pasture based on chemical analysis, in vitro fermentation and modelling. Compare Kikuyu composition against the default values used in the national GHG inventory and estimate how the management of this pasture affects methane production potential.

Updating Pork Industry Emissions Inventory

New Zealand Pork

$40,000

Updating country-specific inventory data for the swine industry, to account for changes in the industry since the previous update in 2010.

N2O emission factors for fertilisers

AgResearch

$340,000

Undertake seasonal N2O emission measurements to evaluate the values used in the inventory for urea, ammonium sulphate, and diammonium phosphate.

Modelling pasture data at farm-scale

Massey

$299,902

Undertake a proof-of-concept to illustrate the utility of mapping farm-scale pasture quality data.
