Where are conservation efforts most needed and most likely to improve the human
condition?
Can we identify “life raft ecosystems” ?
= Areas with:
• high rates of poverty (% undernourished)
• large portion of economy dependent upon nature (agriculture, fisheries, logging)
• severely degraded ecosystem services

Principles
• People are fundamental• Human and Natural systems are tightly coupled.• Ecological processes in the portfolio of options.• Multifunctionality: trade-offs, synergies,
interactions• Resilience: shocks, transformation and feedbacks• Recognize we might have to modify ecosystems• Multi-scale: basin as maximum extent + Global

Through targeted impact pthways in focal regions and at the global level

South East Asia: Mekong Focal Region
![Page 20: Dialogue Session: Ecosystem Services and Resilience of three basins (Volta, Nile, and Mekong)](https://reader035.fdocuments.us/reader035/viewer/2022081602/555b5192d8b42a16758b50de/html5/thumbnails/20.jpg)
GOAL:better targeted investments in water, land, energy and agriculture writ large so they are sustainable and socially inclusive, and national growth and poverty goals can be met by supporting the natural resource base
![Page 21: Dialogue Session: Ecosystem Services and Resilience of three basins (Volta, Nile, and Mekong)](https://reader035.fdocuments.us/reader035/viewer/2022081602/555b5192d8b42a16758b50de/html5/thumbnails/21.jpg)
What is the nature, distribution and value of ES in an increasingly commercialized agricultural system & how is it going to affect local livelihoods in the future?
How would management of water, land and other ecosystem need to be adapted to improve food and nutrition security in the least food-secure GMS countries?
What policies and institutions can communities &
policymakers use to enhance the resilience of
the GMS ES in the long term under pop & ec
growth, CC & globalization?
To move toward resilient ecosystems in the Greater Mekong Region while also achieving growth and poverty
reduction goals will require tradeoff analysis at the regional, basin-wide, GMS-wide and global level under
alternative development pathways that consider investments and policies across water, land and energy; in
food and nutrition; and associated governance and institutions.

*In 12 years from now, the majority of the poor in Africa will be living in urban as opposed to rural areas.

Main questions for WLE
Can WLE guide investors and decision makers to
(i) Better target sustainable agricultural
investments (in the rural north)?
(ii) value and manage ecosystem services under
increasing demands on water, food and energy in
both, the fragile north, and the growing peri-urban
landscapes of the south?

East Africa – Nile Basin Countries
![Page 28: Dialogue Session: Ecosystem Services and Resilience of three basins (Volta, Nile, and Mekong)](https://reader035.fdocuments.us/reader035/viewer/2022081602/555b5192d8b42a16758b50de/html5/thumbnails/28.jpg)
The Opportunity
• Huge development investments in most countries, affecting land use Include growth corridors, commodity corridors,
irrigation and hydropower dam development, upper watershed conservation, food security programs
• Multiple futures are possible in this evolving context
The challenge is to support a sustainability agenda within existing and evolving processes and investments to achieve green, resilient and equitable growth in the countries of the Nile Basin.
![Page 29: Dialogue Session: Ecosystem Services and Resilience of three basins (Volta, Nile, and Mekong)](https://reader035.fdocuments.us/reader035/viewer/2022081602/555b5192d8b42a16758b50de/html5/thumbnails/29.jpg)
Trends and Intervention Areas• Huge diversity in resources, political and economic development• Strong dependence on agriculture, especially rainfed, and natural
resources• Rapid population growth and other demographic pressures,
urbanization, feminization, marginalization• Degradation of natural resources and ecosystem functioning is
pervasive
1. Negotiating trade-offs in
ecosystem services during infrastructure development
2. Achieving sustainable land
management in degradation hotspots
3. Strengthening equity and the role of
women during sustainable intensification
