Food Resources


The 3 major sources of food for humans are: - the croplands, the rangelands and fisheries.

The croplands provide the bulk amount of food for human. Yet though there are 1000s of edible plants in the Earth, solely 4 essential crops (potatoes, rice, wheat and corn) account for many of the caloric consumption of human beings. Few animals are raised for milk, meat and eggs (for example. poultry, cattle and pigs) are as well the croplands are fed grain.

The rangelands provide a different source of milk and meat from animals grazing (for example: goats, cattle and sheep).

Food Resources

The fisheries provide fish which are a major source of animal protein in the Earth, particularly in coastal areas and Asia. As people become more affluent, they incline to consume more cheese, milk, meat and eggs.


Types of Food Resources

In the food resources, there are 2 kinds of food production are as follows: -

1. The industrialized agriculture.
2. The traditional agriculture.


    


Industrialized Agriculture

The industrialized agriculture is called high input agriculture since it uses large amounts commercial fertilizers for field, the pesticides, fossil fuels and water. The large fields of monoculture (single crops) are planted and the plants are selectively covered to produce high productions. Large amounts of grain farmed by this process as well further the production of large numbers in feedlots of livestock animals.

Most of the food made by industrialized processes is traded by farmers for profit and this kind of food production is most common in modernized nations because of the involvement of high expenses and technology. Still, the large industrialized plantations specializing in a single cash pasture (for example. crop specifically advanced for profit such as coffee, coca, bananas) are found in some developing nations.


Traditional Agriculture

The traditional agriculture is the most widely used form of production of food, happening mostly in developing nations. This can be classified later as either traditional intensive agriculture or traditional subsistence and the differences between the 2 involve the relational amounts of food produced and resources input. The subsistence agriculture practices only animal and human labor and only produces enough food for the families of farmer's.

The traditional, intensive agriculture uses more labor of animal and human, irrigated water and fertilizers. This may as well involve growing processes such as intercropping designed to maintain soil fertility rate. The intercropping involves planting 2 crops at the same time (for example, nitrogen-fixing legume crop with a grain pasture). Increased production resulting from the more intensive processes provides sufficient food for the farmer's family and for marketing to other people in the local region.
