Outline of Presentation
• The background
• The case studies
• The solutions
Highland-Lowland Linkage in Asia
Predicted Change in Mean Annual Temperature 2000 - 2050
Average 1.6 deg to 2.5 deg C by 2050
DAMS +
What Impact on Nature?
Less Ecosystem Function
Means
Cascading effects in
< water storage
< soil nutrients
< carbon storage
< less productive
What Impacts on PEOPLE?
more RISK? less RISK?
For local and downstream?
Study sites
PAKISTAN
Poverty ---vulnerability
Shifts in cropping patterns
Water tenure vague
Conflicts --mediation
Flash floods landslides
Men migrating away
NEPAL
Drought primary
<surface water
Pests>>>use more chemicals
Impacts on farming
Seeking outside cash jobs
CHINA
Villagers:
Temperatures rising
Precipitation down
Snow line rising
Glaciers retreating

Farmers Need to Adapt
 Too much water and too little
water from upstream (change)
 local planting patterns (timing)
 markets (switching to
commercial crops)
 government support (statefunded water storage)
What can be done NOW
to build adaptive capacity
for climate and socioeconomic change?
Hybrid Knowledge
NOT JUST LOCAL ANYMORE
Co-produced

Changed water-food-energy nexus
Xu JC, Grumbine RE, 2014. Integrating local hybrid knowledge and state support for
climate change adaptation in the Asian highlands. Climate Change 124: 93-104
Solutions
1. Integrate science-based
conservation with local hybrid
knowledge
 Ecosystem functions
 Nature conservation
 Human livelihoods
LINKED TOGETHER
Climate-Smart Landscapes
Optimize climate mitigation and adaptation for
agricultural lands linked to habitat conservation plans
 Produce more food
 Sequestrate more carbon
 Use less/little water
2. COORDINATED PLANNING
COORDINATION
Not just a good IDEA-----Supported by good INFORMATION
Shared benefits from WATER RESOURCES
The Best PLANNING
Evaluates tradeoffs between conservation of
nature and local needs
Prioritizes costs and benefits (at watershed and
river basin level)
National and NGO plans connected better to
local implementation realities
INVOLVES LOCAL PEOPLE
3. Recognize the role of governance
Coordination of science with local hybrid
knowledge is political ----Transboundary water resource management is
also political -----
better governance
Water decision is a political decision
FUTURE IS NOW
“actions taken today will
change Earth in 20 years”
--IPCC 2014

financially supported by IDRC
