What are the IMPACTS ?

Page 10: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

10

Growing constraints to access grazing and water resources

High GHG emissions per unit of protein produced…

…but many other products: livestock as saving/insurance, economic activity, social role

DIFFERENT SYSTEMS AND DIFFERENT PURPOSES

Cattle herd, Ferlo, Senegal

Page 11: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

11

Global chain, imported feed

Lower GHG emissions per unit of protein produced…

… but other environmental impacts: nutrient pollution, potential land use change associated with imported feed, impacts on biodiversity

DIFFERENT SYSTEMS AND DIFFERENT PURPOSES

Pig farm, Chonburi, Thailand

Resources: ~ 50% of roughages, 20% of silage, 30% of concentrates

High productivity: 20% of the global number of dairy cows, 73% of the global milk production

Main sources of emissions: enteric fermentation, manure, fossil energy use

DIFFERENT SYSTEMS AND DIFFERENT PURPOSES

Dairy production, OECD countries

Page 13: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

13

Grass-fed systems are dominant

6.7% of slaughtered animals were fed in feedlots

Land use and land use change is the main source of emissions, with an impact on other environmental criteria (biodiversity)

DIFFERENT SYSTEMS AND DIFFERENT PURPOSES

Beef production, Brazil

Strong relationship between productivity and emission intensity

CONTRIBUTION TO CLIMATE CHANGE

AGRICULTURE: 20 to 30 % of anthropogenic climate gases; 2/3 from livestock (7.1 GT CO2eq)Overriding role of ruminants

MOST IMPORTANT SOURCES:

• Enteric methane• Feed production• Animal waste• Land use

• Water use: 29% of total agr. water use

• Impact on vegetation and water cycles – higher run-offs• Water pollution: local impacts in areas of high animal concentration

LIVESTOCK AND BIODIVERSITY

EXTENT OF PASTURES: 26% OF ALL LAND – both positive and negative impacts

• Arable land use for feed and expansion• Aquatic systems (nutrient loading)• Positive roles

What are the RESPONSE OPTIONS ?

Page 24: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

RESPONSES

• Efficiency of resource use – land, water, nutrients

• Emission intensity – CO2 eq per unit of product

• Sustainable intensification: feeds, genetics, health

• Reduce waste through recycling and recovering nutrients and energy

• Requires incentives, regulations and continuous innovation

INCREASE EFFICIENCY

Page 25: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

25

• protect assets, enhance multiple functions of livestock in smallholder and pastoral systems

• Integrated landscape management (optimize contributions rather than maximizing output) for food, biodiversity, water, cultural values

• Address overconsumption – healthy diets

• Reduce food-feed competition

RESPONSES

ENHANCE LIVELIHOODS AND HUMAN WELL-BEING

Page 26: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

• Limit livestock’s expansion into valuable eco-systems

• Integrated land use management (in particular in fragile eco-systems)

• Protect water resources

• Requires incentives and regulations

RESPONSES

PROTECT RESOURCES

Page 27: Livestock and the environment: Drivers, impacts, responses

Meeting/Workshop title • place and date

• Of global commons (e.g. climate)

• Of local commons (e.g. communal grazing, water)

• Incentive schemes (payment for environmental services, carbon markets)

RESPONSES

INCREASE RESILIENCE

• Livestock as a tool of adaptation

• improve coping capacity with shocks

IMPROVE GOVERNANCE

SUMMARY

o Large environmental impact, negative and positive

o Context of growing demand, climate change and growing scarcities

o Diversity of systems, issues and responses

o Large potential to respond; social and economic co-benefits

o Requires pro-active policies, incentives and innovation
