Method Descriptions and Tools
Information Storage and Databases
Models
Visualization (examples: maps, graphics, charts…)
Decision analysis (examples: Adaptive management,
Multi-Criteria Decision Analysis, Trade-off analysis,
Linear Programming)
Challenges in Building DSS
• DSS almost always focus on one sector’s (or
discipline’s) tools and concepts
• Model integration is difficult and technically
challenging
• DSS are not always helpful in unearthing assumptions
• Transparency versus Ease of Use
• Integration with scenario planning and communication
- “More gaps than links” (Mike Brklacich, 2005)

Useful Questions
• Who will use these IGP Decision Support Tools?
• What decisions need to be made?
– Over time?
– Over space?
– Adaptively?
• How do you or your constituents currently make decisions?
• What new techniques are you willing to explore?
• What are your information, support and communication
needs?
– Training/Workshops? Reports? Web Tools?
• What does transparency in decisions mean to you?
– What does it look like?
– What level of transparency is appropriate?
And remember…you can always change your mind…
QnD Model
• QnD™ – “Questions and Decisions™” or
“Quick n Dirty”
• A fully integrated Graphic User Interface
(GUI) with a flexible model engine
• One model - Many ecosystems
– Java code / XML inputs
– Dynamically instantiated objects
• Java-based deployment in web browsers
• “Fast Deployment” (weeks/months)
• Spatial simulation with GIS linkage
• Multiple time steps
• Multiple maps/graphs/files for output
variables
“Simulation Engine”
“Game View”
Developer’s point of contact
User/Player’s point of contact
Integrates information
Communicates information
Objects: Components, Processes and Data
“Widgets”: Maps, Charts, Warning Lights,
Text, Sliders, Icons, Buttons
Calculation of state variables
User choices – management settings,
simulate fast or slow time step, reset
subComponent
subProcess
QnD:Game View
User-Defined
“Slow and Fast”
Time Steps
Management Options
Reset Button
“Warning Lights”
Tabbed panes with several
time series charts
Mouse-driven
Chart and Text
Display
Spatial Maps of Ecosystem Indicators
“Game View”
Actors
Players: Interact mostly with the game view.
• Explore management responses, adaptive opportunities,
trade-offs for different scenarios.
• Provide reality checks
• Have some interest in the engine structure in their area of
interest
“Simulation Engine”
• Provide ideas and directions for further iterations
subComponent
Developers: Interact mostly with the engine.
• Design and implement engine/game view through XML
files.
• Provide formal calibration/validations
subProcess
• Implement ideas and directions of Players
• Have some interest in the model code
QnD Java Source Code
GameDriver.java
ModelCreator.java
Coders: Interact mostly with the QnD source code.
• Develop java code to expand engine and game view utility
PrimaryGameFrame.java
• Create new programming code for ideas from Players and
Developers…
QnD: Development Methodology
Genesis Session
Prototype QnD Game View and Simulation Engine
• Talk about the system, goals, desires
• Explore current management options
• Gather initial maps/data
• Brainstorm about desired management options, relevant
information and socio-economic realities
• Rough estimate of components, processes and data
• Simple information
• Deployed in limited circulation for calibration/reality checks
Iterative Sessions 1…n
Deployed QnD Model
• Refine goals, objectives
• Explore current and possible management options
• Calibrate/Validate engine performance
• Revise Game View for relevant management information
• Make changes concerning management options, relevant
information and socio-economic factors
• Player/Developer reviewed components, processes and data
• More relevant information
• Brainstorm about desired management options, relevant
information and socio-economic realities

IGP Decision Support Tools
Ludihana, Central Punjab, India:
wheat and rice predominate, slow to
stagnant productivity growth,
groundwater dependent, lots of
investment, high income levels,
functional policy support.
Gujarat, Punjab, Pakistan:
wheat dominates, food selfsufficient, mixed irrigation,
high level of infrastructure,
moderate income levels,
policies function.
Vaisahali District, Bihar, India:
rice preferred, low infrastructure
investment, flooding, low income
levels, out migration, little
government policy support.
Ruhani Basin, Terai of Nepal:
rice preferred, transition zone,
seasonal flooding, out-migration,
sharecropping dominates,
urbanization increasing.
Greater Faridpur, Bangladesh:
rice dominates, flooding and concern
over salt water intrusion, low income
levels, government institutions fail.
