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 Contributing factors of Livelihood Vulnerability Index Socio-demographic profile 1 0,9 Natural disaters and climate variablility Livelihood strategies 0,8 0,7 0,6 0,5 0,4 0,3 0,2 Water Social networking 0,1 0 Food Knoweldge and skill Health Finance LVI index Lijiang (n=433) Lijiang 0.409 Melamchi (n=365) Melamchi 0.505 Chitral (n=381) Chitral 0.443 1 = MOST VULNERABLE 0 = LEAST VULNREABLE Contributing factors of Livelihood Effect Index Human capital 1 0,9 0,8 0,7 0,6 0,5 Physical capital 0,4 Natural Capital 0,3 0,2 Financial capital Social capital LEI index Lijiang (n=433) 0.398 Melamchi (n=365) 0.503 Chitral (n=381) 0.446 1 = MOST EFFECT 0 = LOW EFFECT 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 Local/Traditional Market-oriented Government support 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 The Asian highlands Project is financially supported by IDRC Thank you!
