TRAINING ON FERTILIZER DEMAND FORECASTING
Patrick Heffer, IFA
19 April 2013Moscow, Russia
What Is IFA?
IFA in Brief
Non-governmental organization representing the world fertilizer industry
About 540 members in 85 countries( including Uralkali and many other Russian fertilizer producers)
Based in Paris Organized around three standing committees:
o Technical
o Production and International Trade
o Agriculture Main activities: market analysis, issue management/
advocacy, conference organization
IFA Agriculture Committee
Four objectives:
Address issues facing fertilizerdemand
Promote the efficient, balancedand responsible use of fertilizers
Improve the public image of fertilizers
Develop reliable and authoritative fertilizer demand forecasts
Reports on demand forecasts twice a year
Annual Conference (May/June)medium-term (5-year) forecasts
Enlarged Council Meeting (Nov/Dec)short-term (1-year) forecasts
Improving the forecasts
Develop network of correspondents
Guidelines for a crop-based approach
Regional training programmes
IFA Agriculture Committee
Develop reliable and authoritative fertilizer demand forecasts
IFA’s Fertilizer Demand Forecasts
Current strategy
Rely on information provided by a network of correspondents in ~50 countries
Heterogeneous inputsessentially due to different methodologies used depending on the countries Trend forecasts Government objectives Recommended application rates Econometric model (e.g. India, Brazil) Crop-based / expert-based model (e.g. EU, USA)
Methodology and Information Used by IFA
Correspondents are not enough
Use additional sources of info (reports, articles…) on: Economic context, weather,
policy factors Global agricultural situation
Check consistency between national forecasts and the global scenario
Forecasts provided by the correspondents are revised in more than half of the countries !They are almost always revised down.
And checks are needed
Fertilizer demand forecastsare cross-checked with forecastson the supply side
To ensure consistency between the two sets
To issue forecasts on the supply/demand balances
Methodology and Information Used by IFA
National forecasts are the starting point: They provide
the foundation for developing regional and global forecasts
High margin of error
Mostly over-estimation
Small margin of error
Balanced fluctuationsaround actual demand
Objective
Importance of Good National Forecasts
Objective - Improve national forecasts, which should resultin turn in better regional and global projections
Developed guidelines for a crop-based, expert-based forecast
On-the-ground training programmes
IFA Training Programme on Fertilizer Demand Forecasts
Crop-Based, Expert-Based Forecast
Why Is It the Preferred Methodology?
What is a Good Forecast?
….. the most likely scenario
Independent from: Commercial pressures Governmental objectives Fertilizer recommendations
As realistic as possible Not too optimistic over-investments Not too pessimistic would endanger food
security Often more conservative than governmental targets
Types of Forecast Methodologies
Trend analysis
Growth rate models
Production/trade models
Econometric models
Crop-based, expert-based models
Why Does IFA Recommend Using a Crop-Based, Expert-Based Approach? Can be used on a consistent basis across all the
countries and regions
Yields much more accurate forecasts than the trend analysis, growth rate models and production/trade models
Does not require large databases and knowledge in econometrics as econometric models. Also, more accurate than econometric models
Explains where changes in demand are anticipated to come from
The Four Stages of
a Crop-Based, Expert-Based Forecast
The Four StagesThe Four Stages
Our Goal: “To Arrive at a Realistic, Objective, and Defensible Forecast”
Main Steps:
I. Create a Historical Database or ‘Base Year’
II. Develop a Qualitative Scenario: Outlook Conditions
III. Prepare the Quantitative Forecast
IV. Validate the Forecast
I. The Historical Database Overview
Consists of Data for 3 Forecast Components:
1. Area Planted to Major Crops
2. Percent of Planted Area Fertilized by Nutrient and Crop Type
3. Average Application Rates of Nutrients by Crop Type
I. The Historical DatabaseData Collection
1. Area Planted to Major Crops
Identify the Major Nutrient Consuming Crops
Develop a Database:
• Major Crops
• Other Crops
Potential Problems
• Only Harvested Area Data is Available
• Data Only Available for Some/Few Crops

II. The Qualitative Scenario
“What Will the Future Look Like?”
Develop Assumptions About Conditions That Will Impact Crop Acreage and Nutrient Application
Consider• Domestic and World Economies• Crop Market Conditions• Fertilizer Market Conditions• The Regulatory Environment• Infrastructure Investments or Limitations
Avoid• Government/Industry Targets
III. The Quantitative ForecastApplying Your Qualitative Conditions
“For Each Crop, Consider Impact of Stage II Assumptions on Each Forecast Component”:
Area Planted
Impacted by:• Crop Prices • Weather • Government Policies • Changes to Demand• Infrastructure
“For Each Crop, Consider Impact of Stage II Assumptions on Each Forecast Component”:
Percent of Area Fertilized and Application Rates
Impacted by:• Crop Prices and Yields• Fertilizer Prices and Availability• Soil Type, Moisture, and Weather• Policy Changes
III. The Quantitative ForecastApplying Your Qualitative Conditions
IV. Forecast Validation
Recall Our Goal: “To Arrive at a Realistic, Objective, and Defensible Forecast”
The Final Step: Verify That the Forecast Meets These Criteria 1. Cross Check Results2. Seek Out Supporting Data3. Compare to Other Methodologies
• Trend Forecast• Econometric Model if Available
Once Comfortable With the Forecast, Explain Results
Concluding Remarks
Maintaining Your Forecast1. Update Your Stage II Assumptions Regularly2. Anticipate/Explain Structural Changes
• Historical Data• Forecast
3. Compare Results With Others4. Rely On and Trust Your Own Expertise
Your Forecast Will Improve Over Time• Progressive Increase of Crop Coverage• Progressive Improvement of Data Quality
Crop-Based, Expert-Based Forecast in Summary
Our goal: “to arrive at a realistic, objective, and defensible forecast”
Main steps:
I. Create a historical databaseor ‘base year’
II. Develop a qualitative scenario:outlook conditions
III. Prepare the quantitative forecast
IV. Validate the forecast
3 variables
