To make such a working model you will have to be FAR more specific. Agriculture encompasses everything from cropping to livestock production to fruit, vegetable and fish production. You will have to choose the vast number of enterprises that are found in the field of agriculture to make a working model, something that you are interested in doing. And as for technology, you will need to find the technology that is involved in that agricultural enterprise. You will need to do a lot of research about the particular agricultural area you are wanting to work on as well as the technologies involved in it before you can make a working model. Once you've done your research, then you can start to get creative, start thinking of what kind of working model you want to have and how you are going to build it.
the most simple way to make a working model on food security is to surf net! lol!

You could create a still model on the 3d modelling software named blendr. NOTE THIS WILL ONLY WORK IF YOU HAVE THE LATEST DRIVERS

In order to find out how working models for computer exhibitions works you will have to do a few steps. You will first have to go online and download the books of information.
i wont tell the answer get lost
Use of new technology can help make the working environment safer than it was, but it can also make it less safe. Any technology must be used with care and forethought to ensure it is used safely.
Today it is high technology and a strong military presence instead of agriculture.
