Their progress and wealth is highly dependent on the harvests, and the price of grain. They probably have to import some industrial products and if they had a bad year (weather, other catastrophies, poor technology) they can't get the necessary amount of industrial products in exchange for their surplus e. g. in grain. There are so many standards and requirements about the quality of food production that no country can survive solely on agriculture without high quality technology (machines, unharmful fertilizers, research-based breeding, etc.).
The production of crops and farm animals for sale, usually with the use of modern technology: commercial farming methods.
A rugged area with large variations in elevation would have high relief, whereas a relatively flat location would have low relief.
Maps that capture data approximately alleviation are termed topographic maps. Maximum geologic maps include topographic information inside the form of contour strains.
Comfort is the distinction between lowest and highest elevation in a location. Only a few surfaces on the earth are genuinely flat. We describe deviations from flatness as relief.
Similarly to showing absolute elevation, contour strains, by means of their spacing, monitor the steepness of slopes at a look. On a steep slope, they have got close collectively.
