the cgiar research program on water, land and ecosystems (wle)
DESCRIPTION
The CGIAR Research Program on Water, Land and Ecosystems (WLE) combines the resources of 11 CGIAR centers and numerous international, regional and national partners to provide an integrated approach to natural resource management research. This program is led by the International Water Management Institute (IWMI). This presentation provides an overview of the thematic areas that the research is categorized into as well as the focal regions where we work.TRANSCRIPT

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

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...

Gender embedded
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 ?
