What influences the expansion of agricultural land as noted in the text?

The expansion of agricultural land is primarily influenced by factors that directly relate to the agricultural sector. In this context, technological advancements in farming play a crucial role. These advancements lead to more efficient methods of planting, harvesting, and managing crops, allowing farmers to cultivate larger areas of land effectively. Improved irrigation systems, the development of high-yield crop varieties, and better pest control methods all contribute to expanding agricultural productivity and consequently, the amount of land needed for agriculture.

In addition, government policies supporting agriculture can create incentives for farmers to expand their operations, whether through subsidies, land grants, or support for sustainable practices. Urbanization, while it can transform rural landscapes and create challenges for agriculture, generally does not contribute to the expansion of agricultural land but rather to a decrease as urban areas expand into previously agricultural regions.

Therefore, the correct response centers on technological advancements, highlighting how these innovations facilitate the efficiency and expansion of agricultural activities.
