As we have been studying the sections of the Rural part of the course I have been emphasising the types of question you may be asked for shifting cultivation, intensive subsitence agriculture and extensive commercial farming. The farming system, landscape, population density and changes are all very common and you must be able to asnwer for all three of our Case Study areas.
The Google Earth images are well worth searching out for yourselves again as well as recalling the photographs you have been shown in class and those in your text book too.
The BBC bitesize site has some rural questions so make use of that too.
