Biodiversity for the livestock
sector
Status, trends, drivers, gaps and
opportunities
CGRFA Special Information Seminar
Biodiversity for food and agriculture: take stock for the future
Rome, 13 April 2013
Different systems and functions
Ca 40% of agricultural GDP
1980-2010:
• 4% production growth p.a.
• 7% production value growth p.a.
Livelihoods of 70% of rural poor
Livestock biodiversity
• <40
domesticated
species
• Hardly any wild
relatives
• 5 species of
major global
commercial
importance

Ecosystem services
At species level usually
Livestock – biological basics
High on food chain
• use ca 1/3 of global land area
– 3.4 bn ha for grazing + 470 mill ha for feed
• contribute to biodiversity loss
– threat to 306 of the 825 terrestrial eco-regions (WWF)
– major threat to 1699 endangered species (red list) (IUCN)
Closely related to humans
• influence agro-ecosystems’ ability to provide
health-provisioning services
Mobility
Field preparation, irrigation, post-harvest processing, transport
Supporting: Nutrient recycling
Nutrient “mining”, transport and
concentration
– Increase in soil fertility / heterogeneity
– Unknown biodiversity effect
Fuel and waste recycling
Seed scarification and dispersal
Regulating services
Well managed grazing
• Biodiversity
• Structural heterogeneity
• Shrub and fire control
• SOM, C-sequestration
• Water cycle
• Local breeds get
recognized as part of
culture and landscape,
and as attractive for
tourism
Cultural services
• Insurance
• Exchangeable asset
• Entertainment
Main drivers and threats to breed diversity
Other
Replacement of breed functions
Loss of production environment
Loss of labour force
Disease and disease control
Lack of functional institutions
Socio-political instability
Poor conservation strategies
Poor livestock sector policies
Economic and market drivers

Information gaps
Locally adapted breeds
• Population size and structure, and distribution
• Phenotypic, genetic and economic
characterization
• Genetic improvement programmes
• Hard data on ecosystem services
Highly selected commercial breeds
• Impact of narrowing within-breed diversity
• Physiological limits (production and health)
• Reconcile production with welfare and
environment issues
Future challenges / opportunities
•
•
•
•
•
•
•
•
•
Genomics and metagenomics ...
Phenotyping and phenomics - bioinformatics
Reproductive technologies
Conservation programmes, technologies and safety
Optimizing genotypes for production environments
and vice versa
GMOs for resource use efficiency
Sustainable use and development
Adaptation in ecological / evolutionary terms, incl.
host-pathogen interface
Application of the ecosystems approach, system
boundaries
