Evaluation of the Emissions Trading Scheme (ETS) in dis-incentivising deforestation. Deforestation levels with and without the ES and at various carbon prices.

The report presents recommendations for country-specific EF1 values for farm dairy effluent (FDE) and urea fertiliser. These recommendations are based on research conducted across New Zealand to quantify EF1 (% of applied N lost as N2O-N) under contrasting soil and climatic conditions.

A review that locates and dissects multiple studies of relevance to the magnitudes of FracGASM and FracGASF as used in New Zealand's current N20 inventory. Currently the NZ N20 inventory uses the IPCC defauls of 0.2 and 0.1 for FracGASM and FracGASF respectively.

The report presents updated algorithms for suitable use in the national inventory that suggest improved predictions and a better fit of the data obtained on enteric methane emissions from sheep.

Estimating and examining he enteric CH4 emissions from sheep - using an IPCC Tier 2/3 approach which comprises detailed population, performance, feed characterisation, and the estimation of dry matter intake (DMI) for each category of animal.

This report reviews the current status of the measurement programme of methane (CH4) emissions from NZ's farmed ruminant livestock using the "SF6 tracer technique" including the quantitative understanding of the main determinants of CH4 emissions.

The aim of the results presented in this report is to compare the CH4 emissions per kg DMI from groups of lambs fed intakes of 0.8, 1.2, 1.6 and 2 times maintenance with the CH4 emission from ewe and wether lambs.

The aim of the results presented in this report is to compare the CH4 emissions per kg dry matter intake (DMI) from a group of ewes at 122-132 days of gestation when fed 2 x energy maintenance pasture intakes with CH4 emission values from a cohort of non-pregnant ewes fed at 1 x energy maintenance.

Determination of methane emissions per unit of intake in young dairy heifers compared to mature cows. With current national inventory measures identifying a single value for cattle regardless of age, the aim of the trial is to determine if CH4 emission per kg of DMI are the same for young dairy heifers and mature dairy cows.

A general overview of the methods used to estimate enteric methane emissions from New Zealand ruminants and provides full details of the algorithms used, along with the sources of all data used in the calculations.

The equations used by the National Enteric Methane Inventory (NEMI) to predict the energy requirements of farmed ruminants were reviewed and assessed for the applicability to New Zealand conditions - Evaluating individual factorial components of MEtotal for dairy and beef cattle, sheep and deer.

The study was carried out to examine the effect of level of feed intake on methane yield in sheep fed a fresh forage diet covering the range of feed intake that will occur in practice on farms.

The objective of this report was to review the key factors used to estimate non-CO2 greenhouse gas emissions from cropping systems. Non-CO2 greenhouse gas emissions (nitrous oxide and methane) from cropped land are accounted for in the New Zealand greenhouse gas inventory.

This report classifies organic soils against the IPCC definition of organic soils with the object of clarifying the distinction between cultivated and managed organic soils, and evaluating the area of organic soils in New Zealand as at 1990. Organic soil definitions were proposed for LULUCF and Agriculture sectors of the National Greenhouse Gas Inventory.

A database of nitrogen (N) measurements created from studies of cattle (beef and dairy), sheep and deer where intakes and partition of N have been collated. The data assesses the current equation used in the New Zealand greenhouse gas (GHG) inventory model to estimate the partitioning of excreta N into urine and faeces (dung).
