Final answer:
Ample grazing and farmlands are typically located in regions with suitable environmental conditions for agriculture, such as Australia's grasslands and China's fertile river valleys. The population density is greater near resources like arable land. In some cases, such as US dairy farming, operations are situated close to urban centers to satisfy the demand.
Step-by-step explanation:
The ample grazing and farmlands are often located in regions with suitable environmental conditions that enable agricultural productivity. This includes areas with well-watered soils, moderate temperatures, and fertile land. For example, Australia's extensive grasslands support large-scale livestock farming, while the fertile river valleys in China provide substantial food production to support its population. The population density tends to be greater near resources that support human life, such as arable land and water sources, leading to higher concentrations of people in these areas. Dense populations in areas like Bangladesh, Sri Lanka, and Pakistan are supported by the very high yields from the arable land available, even though this space is limited.
In comparison, regions with harsher environments, such as Africa's arid transitional belts, are less favorable for settled communities and thus have a lower population density. These areas often rely on nomadism and the herding of grazing animals. Additionally, some rural populations face challenges, including impoverished conditions and inadequate access to food. In the United States, dairy farms, and by extension hay farming, tend to be located near population centers in states like New York, Illinois, and California, to reduce transportation costs and address the demand created by these population centers.
