Intensive subsistence farming is a type of farming that is practiced in areas with a high population. This type of farming involves the cultivation of small plots of land with a high input of labor and a low use of technology and capital. It is characterized by the production of crops and livestock for the subsistence of the farmer and their family, rather than for commercial purposes.

Here is a detailed explanation of why intensive subsistence farming is practiced in areas with a high population:

1. Limited land availability: In areas with a high population, land is often limited and fragmented. As a result, farmers have small plots of land available for cultivation. Intensive subsistence farming allows them to make the most efficient use of the limited land by maximizing productivity and yields.

2. High labor availability: In densely populated areas, there is usually a surplus of labor. Intensive subsistence farming requires a significant amount of labor for tasks such as plowing, sowing, weeding, and harvesting. The availability of labor allows farmers to engage in labor-intensive farming practices.

3. Lack of capital and technology: Areas with a high population often have limited access to capital and technology. Intensive subsistence farming does not rely heavily on expensive machinery or advanced technology. Instead, it relies on manual labor, simple tools, and traditional farming practices, which are more accessible to farmers with limited resources.

4. Subsistence-oriented agriculture: In areas with a high population, the primary goal of farming is to produce enough food to meet the nutritional needs of the farmer and their family. Intensive subsistence farming focuses on growing staple crops and raising livestock for direct consumption rather than for commercial purposes. This type of farming ensures food security for the local population.

In conclusion, intensive subsistence farming is practiced in areas with a high population due to limited land availability, high labor availability, lack of capital and technology, and the need for subsistence-oriented agriculture. This type of farming allows farmers to maximize productivity and yields on small plots of land while ensuring food security for themselves and their families.
