What is Modeling?
• Modeling is way to represent something (real or conceptual)
Do I have all these
things in my computer?
• The representation is known as ‘the model’
These representations help me to understand how the things would be in reality
Why Modeling?
Four Main Reasons / Objectives
•
Descriptive
To characterize the systems.
•
Prediction
To forecast future system behavior
•
Postdiction
To explain after-the-fact what caused a given outcome
•
Prescription
To get guidance on how a system should be managed to meet some goal
General Types of Models
Deterministic
Static
Dynamic
Stochastic
Empirical & Mechanistic
Mathematical
3D

Analysis of Crop Modelling for Climate Change and Food Security
Mission Statement
The aim of the survey was to collate information, opinions and expert feedback across a wide range of people involved, either
directly or in--‐directly, on crop model development and application. The purpose of this was to provide information representing
the crop modelling community’s current views on the state of model development, and how they can be improved to support
research and decision making on issues of climate change impacts, mitigation and adaptation, and food security. From this it is
hoped that improvements in crop modelling capabilities can be utilized to achieve food security, enhancing livelihoods
and improving environmental management in the developing world, considering the threats posed by climate change.

GPS
Geographic Information System
A system designed to manipulate and
analyze geographical data
GIS
Geographic data
Software
• Geographic data: Links the data with spatial information
(e. g. topography, hydrography, roads, agriculture, buildings, etc)
• Depends on Satellite or aerial photography
• GIS combines Geographic data
• Data is organized in thematic layers
• Data is presented in graphical form
• Helps in decision making
Hardware
GIS in Agriculture
• In a map of agricultural area, for example, one layer each for the following could be
produced, i. e., piece of land, soil types, crop yield, specific soil treatment, and irrigation.
• The interrelationship among these layers can be concluded.
• Possible applications are yield data analysis, site specific prescription, irrigation
planning, terrain analysis, crop growth modeling, etc.
Advantages
• Greater support for precision farming
• Better understanding of risk factors
• Higher revenue generation
• Better resource management
• Better policy making
Possible layers for Agriculture
GPS - Global Positioning System
• Space & Land based system to determine position precisely
• Mostly used in Military and Agriculture
• Millions of users around the world
• Hand held or vehicle mounted
GPS-Applications in Agriculture
Computer Vision – Applications in Agriculture
Automation
A Typical Computer Vision System
(Planting, Fertilizing, Spraying, Harvesting)
Sorting
Output
Feature extraction (For Research)
Food quality inspection
Color, leaf-area, water status,
spectral analysis, etc
The theme of computer vision has
been to duplicate the abilities of
human vision by electronically
perceiving and understanding an
image
Conclusion
We need to improve and strengthen our mathematics
Programming capabilities of the students / faculty should be improved
Interdepartmental cooperation for joint research and development needs progress
New courses on state-of-the-art technology must be inducted in the curriculum
Thanks
