El Problema

Page 3: Livestock and sustainable growth: present and future

In order to meet global demands, we

will need

60-70% more food

by 2050.

Food security is at risk

Page 4: Livestock and sustainable growth: present and future

Arable land per person will decrease

Year• World Population• Arable land

20006,1000,000• 0.25 ha

20509,000,000• 0.16 ha

The arable land on the earth is ~3% or 1.5 billion ha

• 30-45% of earth’s terrestrial surface is pasture

- 80% of all agricultural land

• 1/3 arable land used for feed crop production

• 70% of previously forested land in the Amazon = pasture

• 10-18%3 of all global anthropogenic GHG-Other estimates as high as 51%4,5

• Range arises from methodological differences

-Inventories vs. life cycle assessments

-Attribution of land use to livestock

-Omissions, misallocations

2 Livestock and GHG

Source: de Vries and de Boer (2009)

Range of GHG intensities for livestock commodities

• Highest variation occurs for beef, due to variety of production systems.

• Ruminants require more fossil energy use, emit more CH4 per animal.6

Mensaje 1:Ganaderia esta en el ojo del

hurrican en el tema de seguridad alimentario del mundo: emisiones,

uso de la tierra, suministro de proteina

Page 13: Livestock and sustainable growth: present and future

Entonces que se hace? Tres consideraciones

• Los numeros no cuadran, entonces cual es la solucion?– Incrementar productividad– Disminuir perdidas en la cadena (y con

consumidor)– Reducir consumo

Livestock products: Developing countries are hungry for more.

• Growth in animal product consumption has increased more than any other commodity group.1

• Greatest increases in S and SE Asia, Latin America.

-Overall meat consumption in China has quadrupled since 1980 to 119 lbs/person/yr. 2

• Economic and population growth, rising per capita incomes, urbanization

Page 17: Livestock and sustainable growth: present and future

• Between 1961 and 2005 milk consumption in developing countries doubled, meat consumption tripled, and egg consumption increased by a factor of five. 1

3 Livestock consumption patterns

Past and projected consumption of livestock products

Source: FAO (2006a) and FAO (2006b).

• As incomes grow, expenditure on livestock products increases rapidly .3

-GDP growth in E Asia from 1991-2001 was 7% per year, compared to 2.3% in other developing countries and 1.8% in developed countries.

• Consumption is leveling off in developed countries, but more than doubled since 1980 in developing countries (from 31 lbs. to 62 lbs. in 2002).

-Rapid growth led by China, India, & Brazil projected to continue.

…and increasing livestock production, but on less land

Page 29: Livestock and sustainable growth: present and future

It’s all about the livestock…..either improve it’s efficiency, or get out of it!

• Ganaderia si es gran parte del problema, y tiende a empeorar• Solucion viene igual dentro del sector• Ganaderia sostenible tiene que ser holistico en su vision:

• Zero deforestacion• Baja emisiones• Alta productivdad• Generacion de servicios ecosistemicos• Consumo responsible• Bajas perdidas post cosecha

• Sabemos mucho, tenemos ejemplos espectaculares• Como logramos impactos escalados a nivel global/nacional• Politicas/tecnologias/programas/investigacion alineado
