Approximately 20-30% of cultivated land worldwide is irrigated. This percentage varies by region, with some areas relying heavily on irrigation for agriculture while others depend on rainfed farming.

Only 15 percent of the land in China is able to be cultivated. Of this land accounts for only 10 percent of the land in the world that can be cultivated.
Approximately 20% of the world's cultivated land is irrigated, providing water to crops to increase agricultural productivity and ensure consistent yields. Irrigation systems help optimize water use and solve water scarcity issues in regions where rainfall is insufficient for crop growth.

Cultivated land characteristics include soil fertility, water availability, slope, and sunlight exposure. Soil composition, drainage, and pH level are also important factors, as well as the presence of nutrients and organic matter. Proper land management practices such as irrigation, crop rotation, and pest control can help maintain and improve cultivated land characteristics for optimal crop growth.

What is the system of land use control? China is one of the most populated countries in the world. Until September 2006, per capita cultivated land is 1.4 mu (1 ha=15 mu). This means that China has to feed on 1.3 billion population (about 20% of population of world) with the agricultural production of 7% of the land of world. Worse, as China is emerging a new industrialized country, more and more cultivated land is converted to the construction of office buildings, industry complex, condominiums or infrastructure. Another side product of industrialization is the deterioration of environment and this further reduces cultivated land. In order to control the reduction of cultivated land, China adopts the system of land use control. In China, land is categorized as agricultural land, construction land or unused land for different uses from the use purpose of standpoint. Agricultural land means land that may directly be used for agricultural purposes, which includes cultivated land, forest land, grassland, land for water irrigation and land for aquatic cultivation. Construction land means land that may be used to construct buildings, which includes land for construction of urban and rural housing and public facilities, land for mining, land for traffic and water irrigation facilities, land for tourism and land for military facilities. Unused land means land that has not yet been used for agriculture or construction. Further, land for construction is categorized as collective construction land and state construction land. If the land user wants to change the land use purpose, for example, from agricultural land to construction land, approval from government authorities is required.
