NAFTA
|
Two thirds of all agricultural land in Canada is used for grazing
|
Sheep and cattle stations are large, comprising 10,000-50,000 animals
|
Many UK and EU breeds
Sheep - 7,168
|
Fertiliser use in this system will be low due to its extensive nature.
In industrialized countries in 1995, 8.9 Tg N from animal manure was disposed of in industrial grazing systems; 7.2 Tg was applied to land.
|
Enteric CH4 emissions and emissions of N2O from excreta deposited when grazing.
|
EU
|
UK biggest sheep meat producer and all UK sheep production is extensive.
Smaller sheep sectors in other Member States including sheep dairying
EU beef production becoming more extensive due to recent CAP changes reducing incentives for high production
|
Of the 9 million agricultural holdings in EU-27 in 2005, 75% had less than 5 LSU
|
Variety of beef and sheep breeds, often regional/country specific, although some breeds (including a number of French and Belgian beef breeds) have become more widespread
Sheep - 137,429
|
Ruminant livestock are fed on forage diets (such as silage) or compound feeds.
In industrialized countries in 1995, 8.9 Tg N from animal manure was disposed of in industrial grazing systems; 7.2 Tg was applied to land.
Fertiliser use in this system will be low due to its extensive nature.
|
Negative biodiversity impacts caused by under and over grazing on pasture which has developed as a result of well managed grazing
Localised sheep dip (pesticide) pollution problems
Localised biodiversity problems due to vet medicines remaining in manure
|
Countries in transition
|
|
|
Sheep –
Slovenia – 129;
Croatia – 680;
Bosnia and Herzegovina - 995
|
In 1995, 4.0 Tg of N from animal manure was disposed of in mixed/industrial grazing systems. 4.3 Tg was applied in mixed/industrial systems.

Oceania
|
Cattle farming in Australia uses 58% of land for rough grazing – sheep grazing in New Zealand occupies 46% of all land (Saggar et al, 2006).
|
Very large, 100,000 ha not unusual. Some stations (large cattle farms) measured in square miles
|
British/European breeds, often cross bred with tropical breeds (such as Brahmin)
Merino sheep very widespread
Sheep – 140,212
|
In New Zealand, fertiliser use in 2006 was 418 kg * 10^6 of nutrient, which equates to an intensity in 2005 of 309.4 kg/ha (WRI, 2009)
|
25% increase in N2O emissions since 1990 due to increasing intensity of pastoral
land use, towards dairy-farming (Saggar et al, 2006)
