Nitrogen fertilizer reduction for Dianchi
Lake in ChinaSean Penrith
Executive Director
Problem Statement Farming practices in Kunming are polluting Dianchi Lake
55% of the lake's fish population has been killed off by pollution
The lake water is rated Grade V (the worst grade) which makes the water unfit for agricultural or industrial uses
Problem Statement
Nitrogen is the key input to global agriculture and China uses over 1/3 of total nitrogen fertilizer produced Can be produced using either coal or natural gas; China uses mostly coal
Less than 50% of nitrogen is absorbed by plants
Unabsorbed nitrogen damages the environment Water pollution (ground and surface water)
Air pollution (Greenhouse Gas Emissions)
Nutrient management can help!
Nutrient Management Overview
Step 1: Farmers apply lessnitrogen fertilizers to theirfields
Step 2: Credits are generated fromthe resulting emission reductions
Step 3: Credits can be sold on the market and revenue returned to the farmer
Practices that reduce emissions
Reduction in application rate
Cover cropping
Injection into soil
Changing type of fertilizer
Changing timing of applications
Benefits of Carbon Trading
A cleaner lake
More revenue for farmers
Credits to comply with ETS
Reduce GHGs in atmosphere
Generation of Credits
The process is cyclical; the successful sale of credits causes more farmers to want to participate
Scale
Depends primarily on the credits per acre of a project
In the US, this is very low (usually less than 1 credit per acre)
Therefore it is important to be able to aggregate many fields together to make the project attractive to buyers
Data Needs
Based on nitrogen reduction methodologies based on the US corn belt (adaptation needed for Kunming pilot)
Each growing season is one year of the project
Projects need 5 years of historical data to establish a baseline condition
Key inputs needed:
Amount of nitrogen applied (baseline and project)
Nitrogen rate of fertilizer (baseline and project)
Precipitation and evapotranspiration data
Questions
Has NDRC approved any methodologies for nitrogen management on farms?
What crops are grown most often in Kunming?
Is anyone collecting data on nitrogen fertilizers being applied?
Who advises farmers on nutrient management practices?
How do applicable incentive programs interact with nutrient management practices?
The market
7 pilot trading schemes each allow offsets for 5-10% of compliance
National ETS to be launched in 2016
Offset projects allowed are based on CDM methodologies and focus primarily on renewable energy, fuel switching and capture/destruction of methane and other short lived pollutants
