Miyun River Watershed Regional Example
Miyun River Watershed
Only surface water source for Beijing
Miyun Watershed Two major water systems (Chao & Bai Rivers) 15,800 km 2 (> Connecticut) Mountains, forest, Great Wall of China Shared governance – Beijing: 1/4 land area, 20 townships – Hebei: 3/4 in land area, 42 townships
Declining inflow M 0.2 M Stresses on the reservoir Increasing population
Stresses on the reservoir Increasing nutrient pollution Total nitrogen concentration (mg/L) Industrial effluent Wastewater Agricultural runoff
Livelihoods are limited to protect reservoir Mining all iron 47 mines closed in 2000 Aquaculture no in-reservoir cage fishing from 2003 Agriculture shift from grain to fruit trees; shift from chemical to organic fertilizer; eliminate rice paddies Tourism no activities in protection zones (Peisert, Sternfeld 2005; Regele 2008; Kröger et al 2012)
Ongoing efforts in Miyun 1.“Paddy land to dry land” conversion program 2.Distribution of costs and benefits
Program goal: increase water yield & improve water quality Enrolled ha of ag land Payment $ $1300 USD per ha per year 1. Paddy land conversion program
Step A: BENEFITS changes in water yield and nitrogen concentrations to the reservoir Step B: COSTS Payment to farmers, net changes in ag production (rice – corn) Programmatic costs Step C: LIVELIHOOD IMPACTS Difference-in-difference estimates of household livelihood changes (compare participants and non- participants) 2000 Paddy land 2000 Land Use
1. Paddy land conversion program Costs and benefits of the program
1. Paddy land conversion program Livelihood outcomes Income source Is there a difference between participants and non participants? All income 22,728*** Agricultural income -1450*** Non farm income 1089*** Migrant income 5485***
1. Paddy land conversion program Livelihood outcomes Expenditures Is there a difference between participants and non participants? Corn inputs (eg, fertilizer) 525*** Agricultural equipment (tractors, animals) -0.03*** Education 994*** Natural resources (wood, coal, LPG) 105*** Material assets (washer, motorcycle, fridge, car, TV) 0.19***
How can Beijing effectively secure access to water, and how are various populations affected? 2. Distribution of ES costs & benefits
Step A: estimate changes in ES during & Distribution of ES costs & benefits Rural consumption Urban consumption Agricultural value Carbon LOCAL TOTAL - 0 +
Step B: estimate the value of future improvements (RIOS) 2. Distribution of ES costs & benefits
Step B: estimate the value of future improvements (RIOS) 2. Distribution of ES costs & benefits What activities help improve water security?
Step B: estimate the value of future improvements (RIOS) 2. Distribution of ES costs & benefits What activities help improve water security? Where should these activities take place?
Step B: estimate the value of future improvements (RIOS) 2. Distribution of ES costs & benefits What activities help improve water security? Where should these activities take place? Who bears the costs of implementation?

Ongoing work planned in Hainan Island
