numbers/herd structures, feeding rations, commodity trade, prices, utilization of
commodities (food, feed, seed, waste, other), population, nutrition.
 
 
Reference scenario:
 FAO projections 2050 on population numbers and nutritional

Trade-offs and synergies
 
Business-as-usual: 
BAU is not an option, as environmental
impacts will rise till 2050 and further pressure on food availability
may increase
 
Low-input livestock systems: 
synergies between food availability
and most environmental indicators
 
Full organic conversion:
Can produce sufficient food for 9.2 billion in 2050
Positive indicators: GWP, N, P, energy, water, toxicity potential
One negative impact: land, hence deforestation (+450

Ideal scenarios for 2050
Ideal scenarios for 2050
 
Organic livestock scenarios fare best when combined with
reduced concentrate feeds :
-50% still requires additional 250 million ha cropland
Zero use of concentrate feed does not require more lands
 
Global environmental impacts can be mitigated if livestock
production was based on grasslands and residue recycling
 
These extensification strategies can produce 3028 kcal/cap/day
but with consumption of livestock products reduced by 3-4
 
 
Change in livestock availability
 
affects mainly monogastrics

About  36% of world consumption of cereals goes to feed:
developing countries account to 42% of world total and will increase to 56% by 2050
 
Grasslands and pastures reduce inefficient use of arable lands
 
Reduced concentrate feed would yield more food for direct
human consumption while providing multiple ecological services
 
With globally supplying sufficient calorie and protein, the share
of ruminants and monogastrics  differs

Grassfed ruminants will require a better knowledge of nutritional  value of
different type of grasslands for different spp.
 
Feed supply for monogastrics will require novel technologies to produce feed
from agricultural residues, agro-industrial by-products and food waste.
 
Feed sources assessments are needed to estimate national/local:
Chemical composition and nutritional value of feed ingredients
Nutrient balance (identifying surplus and deficits)
Optimizing use of available feeds
Forecasting feed resources in time and space
Generating optimum livestock-feed relationship
Balancing trade-offs in biomass use
Export/import of feed ingredients and prices
 
 
 
 
CONCLUSION
 
Organic Plus
Organic Plus
 
Up-scaling organic agriculture globally is technically feasible
 
But organic standards must be strengthened on animal feed
 
Existing standards on grassfed (USA) or pasture-fed (NZ, UK)
could inform on steps towards concentrates-fee organic feed
 
Organic YES but through a more rational use of biomass and lands

The research presented at the 18th Organic World Congress in Istanbul delves into the Sustainability and Organic Livestock (SOL-m) modeling approach developed by FAO and FiBL. The study aims to explore the potential impacts of global conversion to organic livestock production by 2050 on food security and the environment. Key research questions address organic agriculture's capacity to meet future food demands, implications for land use, and the balance between intensification and extensification strategies for livestock farming. The modeling framework utilizes data from FAOSTAT, scientific literature, and a General Algebraic Modeling System to analyze mass flow components, herd structures, and global agriculture land use patterns.
