The interplay of knowledge and natural resources:
Ensuring the health, wealth andenvironmental benefits of livestock
Tropentag 2014: Bridging the gap betweenincreasing knowledge and decreasing resources17−19 September 2014 Prague, Czech Republic

Key messages-1
• With diminishing natural resources,we’ll have 10 billion people to feedby mid-century, manyof whom will be consumingmore meat, milk and eggs
• Transformation of the livestock systems of developing countries is one of the biggest opportunities we have for a nourished, healthy, environmentally sound and equitable world
![Page 3: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/3.jpg)
Key messages-2
• We can, and should, rely on the creation,diffusion and applicationof our primary ‘natural resource’− scientific knowledge −to transform the futureof livestock production
• We can, and should, ensure that wegrow our food and manage ournatural resources for the benefit of all −and for all generations to come

Knowledge, food and natural resources: Pre-history
![Page 5: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/5.jpg)
Humankind and natural resources before agriculture
Long beforerecorded history,people dependedon natural resources fortheir survival
![Page 6: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/6.jpg)
Humankind and natural resources before agriculture
Before the adventof agriculture,each hunter-gathererneeded about 6.5 sq kmto catch wild animalsand to gather wild foods
![Page 7: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/7.jpg)
Application of knowledge first transforms agriculture: Animals and plants are domesticated
Some 7 to 9thousand years ago, peoplefirst domesticated large herbivores

The (supply-led) Green Revolution was not universal

The Livestock Revolutionis demand-led (not supply-led)

Consumption of livestock productsto 2050
• Globally:An overall increase in per capita daily consumptionof livestock products of 37% compared to 2000
• Commodities differ:– A 2% decrease in global per capita meat consumption
– A 61% increase in global per capita milk consumption
• Regions differ:– In 2000, Africa and Middle East consumed (in total calorie
consumption) 60% fewer livestock foods than the EC
– In 2050, this will be reversed: highest livestock consumption will be in Africa & Middle East, lowest in the EC

Knowledge, food and natural resources:Three plausible scenarios
![Page 30: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/30.jpg)
Scenario #1Developing countries meet
livestock demand byimporting products
Scenario #2Developing countries meet
livestock demand byimporting knowledge
Scenario #3Developing countries meet
livestock demand bytransforming smallholder livestock systems
Three plausible scenarios for livestock growth

The unlimited natural resourceof human will and ingenuity and innovations
Knowledge advances agriculture,while agriculture (the ‘mother of all inventions’)
advances knowledge

Global Agenda for Sustainable Livestock-1
• Global povertyand inequality cannot be addressed without investment in livestock
• Global foodsecurity and health cannot be addressed without investment in livestock
![Page 34: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/34.jpg)
Global Agenda for Sustainable Livestock-2
• Global environmental issues cannot be addressed without investment in livestock
• Investment in livestock needs to produce more, from less, in ways that benefit all
![Page 35: The interplay of knowledge and natural resources: Ensuring the health, wealth and environmental benefits of livestock](https://reader035.fdocuments.us/reader035/viewer/2022062614/546e5486b4af9faa268b4623/html5/thumbnails/35.jpg)
