Sixty percent of Bangladesh's land area is arable, the highest ratio in the world (Ukraine is 2nd, India is 5th). It is also number two in total arable land area in the world (after India, which has three times the population of the US), so, not surprisingly, like County Z in the example above, the US is a net food exporter. Physiological density is a method of calculating the human pressure on arable land, which helps in planning how long an area can produce enough food to feed its By better understanding who is relying on each region of the world, we can better allocate resources and understand how current resources are already being allocated. The idea here is that cities can and should provide much of their own food. The key is making sure that we measure each of the methods because they are all going to be important to understand the rest of the world and how we will go about getting the food and shelter needed for the number of people in each country or city. Arable land is land that is farmed for crops, either actively or in rotation (i.e., is currently fallow but is part of a cropping system). Best study tips and tricks for your exams.
