DESCRIPTION
This presentation by Dr Koko Warner shows focuses on 3 main points: 1. Evidence of climate change-related loss and damage when people face constraints and limits to adaptation and empirical results from Bhutan and Nepal 2. Rainfall variability, food and livelihood security and migration: “Where the Rain Falls” (Rainfalls) Project and empirical results from Guatemala, Peru and Tanzania 3. Conclusions and reflections for policymakers

Building climate change resilience in mountains: evidence
from Bhutan, Guatemala, Nepal, Peru and Tanzania
Building Climate Change Resilience in Mountains - Global Landscapes Forum session
Warsaw, Saturday 16 November 2013
1. Evidence of climate change-related loss and damage
when people face constraints and limits to adaptation and
empirical results from Bhutan and Nepal
2. Rainfall variability, food and livelihood security and
migration: “Where the Rain Falls” (Rainfalls) Project and
empirical results from Guatemala, Peru and Tanzania
3. Conclusions and reflections for policymakers
Presentation outline
The costs of adaptation in Punakha District
Climatic stressor: Changing monsoon patterns: Less rainfall and later
onset
Impact on livelihoods: Reduced water availability for rice
cultivation: impact on food security and income
Adaptation: Adjustments to irrigation practices and access to water,
changes in crop mix, from two to one harvest a year, buying pumps
Loss and Damage: For 87% of survey respondents, the measures are
not enough and/or entail extra costs that could not be regained
Loss and damage results in Bhutan
Preventive and coping measures not enough to avoid
loss and damage from flooding in Udayapur District
Climatic stressor: Increasingly severe flood events
Impact on livelihoods: Crops washed away, damage to houses and
properties, high food prices in the aftermath of floods
Coping / adaptation: Pro-active and reactive; individual and
collective. Examples: construction of physical barriers; livelihood
diversification; sale of assets to buy food.
Loss and Damage:
For 77% of survey respondents, the measures were not enough;
Main adaptation constraint; lack of financial resources
Much time and efforts spent on adaptation measures
Loss and damage results in Nepal
Where the Rain Falls:
Rainfall Variability, Food and Livelihood Security, and Migration
CAR
Research site Main Findings
Guatemala Western Highlands (CabricánMunicipality)
• Populations risk becoming trapped :• Profitability of the main livelihood diversification opportunity (weaving) is decreasing• Migration to the US (main migration destination) is becoming too expensive and risky• Labour demand in the Southern Coastline (second main migration destination) is decreasing
Northern Tanzania (Same District, Kilimanjaro Region)
• Altitude matters: • Human mobility less in highlands (higher precipitation and remoteness) as compared to lowlands (dryer and closeness to cities).• Other intervening factors affecting human mobility along different altitudes (profession, age, gender, education)
Results of case studies in mountains
The key to climate change resilience in mountains is access to livelihood
diversification opportunities (both in situ and through migration)
Research site Main Findings
Peru Central Highlands(Huancayo Province)
• Altitude and access to urban economic opportunities shape livelihood options and migration strategies (daily mobility to nearby city of Huancayo at lower altitude, long-term migration at higher altitude)• Even in complex rural-urban livelihoods systems, climatic and environmental conditions are still relevant for household resilience

The key to climate change resilience in mountains is access to livelihood
diversification opportunities (both in situ and through migration)
Glacier recession and “peak water“ in the Cordillera Blanca, Peru
Basin level versus sub-catchment level
(Bury et al. 2012)
1982
1987
1997
2004
Nearly 100% of randomly sampled households in the valley reported glacier recession, changing precipitation patterns, and drying and disappearing water sources (Bury 2011).
*Switch from glacier-fed to rainfed agriculture
Different demographic structure in phase 4 watersheds
