Four historical Chinese irrigation sites were recognized as World Heritage Irrigation Structures on Thursday, bringing the total number of Chinese projects on the list to 30, the Ministry of Water Resources said.

With the inclusion of the four projects — announced by the International Commission on Irrigation and Drainage in Adelaide, Australia — China has become a country "with the richest type, widest distribution and highest irrigation efficiency of heritage structures", the ministry said.

The ICID is an international organization, created in 1950, that works to boost scientific and technological exchanges on irrigation, drainage and flood control.

It established the World Heritage Irrigation Structures designation in 2014, aiming to protect and promote irrigation projects of historical and scientific value.

The 2,160-year-old Tongjiyan Irrigation System, one of the newly honored projects, is located in Sichuan province. It has a braided-shaped arrangement of canals that helps to increase its flood control capacity.

The project preserves the ecology of the water, which it provides to two cities and four counties and districts in Sichuan, an irrigation area of 34,667 hectares, for the populace and farming.

The Xinghua Duotian Irrigation and Drainage System, in Jiangsu province, stemmed from efforts since the Tang Dynasty (618-907) to prevent flooding and has been in use since then. It is now the world's only irrigation and drainage system located on raised, dry farmland.

The system not only increases local grain production and population capacity in the area, but also creates a unique and pleasant landscape with a variegated folk culture that draws tourists.

Chongyi Shangbao Terraces cover 3,400 hectares in mountainous areas of Jiangxi province, inclining from an altitude of 280 meters to 1,260 meters above sea level.

Construction of the terraces began around the time of the Qin (221-206 BC) and Han (206 BC-AD 220) dynasties, and they have developed into a sophisticated and sustainable irrigation network. The average grain harvest per mu (0.067 hectare) of the terrace has reached over 500 kilograms.

Besides the four Chinese projects, 15 irrigation projects from Australia, India, Iraq, Japan, South Korea and Sri Lanka were also honored this year.

So far, 140 projects from 18 countries have been listed.
