What is one development during the Han and tang dynasty is that contributed to the increase population of southern China?

Answer 1

One development during the Han and Tang dynasties that contributed to the increase in population in southern China was the improvement of agricultural techniques and irrigation systems.

During these dynasties, there were significant advancements in agricultural practices, including the introduction of new crops, improved irrigation techniques, and the development of better tools and implements for farming. These advancements allowed for higher crop yields and increased the overall agricultural output in southern China.

Additionally, the establishment and expansion of large-scale irrigation networks, particularly in the fertile river valleys like the Yangtze and Zhujiang (Pearl) River, greatly enhanced the productivity of the land. The construction of canals and dikes for irrigation purposes enabled the cultivation of larger areas and facilitated transportation, further supporting population growth.

As a result of these developments, the availability of food increased, leading to a growing population in southern China. The increased agricultural output not only sustained larger numbers of people but also provided a surplus that supported urbanization and economic growth in the region.
