The challenges facing our global food

production systems

Food security . . . Exploitation of resources . . .

The challenges

change . . . climatic, demographic, economic

We have exceeded three of the nine Planetary

boundaries – danger of greater risks and

uncertainty emerging

Agriculture is the dominant contributing factor

and the solution

How do we transform agriculture to meet

human prosperity and global sustainability?

By focusing on ecosystem services based approaches

that

• increase agricultural production and

• strengthen people’s livelihoods

A virtuous circle that triggers change to

a more resilient state

Land Degradation is a Classic

‘Wicked Problem’

Now is an exciting

time for renewed

coordinated efforts

towards a ‘land

degradation neutral

(or better!) world’

More than 95 million ha of arable land, or

75% of the total in SSA has degraded or

highly degraded soil

Farmers lose eight million tons of soil

nutrients each year, estimated to be worth

$4 billion...

Towards:

• More equitable access to water,

land and ecosystems services

• Improved decision making - inclusion in resource

management

Research questions:

• The African farmer and her husband: Feminization of

agriculture

• Mother and earth: Replenishing and fostering agriculture

Develop:

• Investable options for women

Our vision:

A world in which agriculture thrives within vibrant ecosystems, where communities have higher incomes, improved food security and the ability to continuously improve their lives

Issues for discussion

What is the relevance of an ecosystem services based approach to unlock agricultural productivity in Africa ?

What are the barriers to such an approach ?
