The East Ghor Canal (Arabian: قناة الغور الشرقية), renamed King Abdullah Canal (قناة الملك عبدالله) in 1987, is the largest irrigation canal system in Jordan and runs parallel to the east bank of the Jordan River. Its main water source is the Yarmouk River and the Al-Mukhaibeh wells within the Yarmouk valley: farther south, additional water flows from Wadi el-Arab and from the Zarqa River. The canal’s design capacity is 20 m3/second at the northern entranceand 2.3 m3/second at its southern end. Water flows by gravity along its 110 km (68.35 mi) length, ranging in elevation from about 230 m (755 ft) below sea level to almost 400 m (1,312 ft) below. The Canal supplies water for irrigation and 90 million cubic meters/year of drinking water for Greater Amman through the Deir Allah-Amman carrier, which has been constructed in two phases in the mid-80s and in the early 2000s. The canal was designed in 1957 and was built in phases. Construction began in 1959, and the first section was completed in 1961. By 1966, the upstream portion to Zarqa River was completed. The canal was then 70 km (43.5 mi) in length, and was subsequently extended three times between 1969 and 1987.

Guanacaste (Nahuatl: Kwahnakastlan) is a province of Costa Rica located in the northwestern region of the country, along the coast of the Pacific Ocean. It is bordered by Nicaragua to the north. The province covers an area of 10,141 km² (3,915 sq mi) and as of 2022, had a population of 404,774. Guanacaste's capital is Liberia. In pre-Columbian times, most of the province's territory was part of the Kingdom of Nicoya (Nahuatl: Nekok Yaotl). Since 1787, a large part of the territory of the current province was a Spanish colonial political-administrative unit with the name of Partido de Nicoya; Through a plebiscite held on July 25, 1824, said territory decided to join the State of Costa Rica, and in 1835 it was renamed the Department of Guanacaste. In the 1980s, infrastructures began to be built, such as the canal represented on the stamp, to favor the development of agriculture. Currently, the economy of the province is based mainly on tourism and agricultural activities.

Shihmen Reservoir (石門水庫) is formed by the dam of the same name on the Dahan River near Taoyuan City. It provides irrigation in Taoyuan, flood control for the Taipei Basin, and hydroelectricity and domestic water supply for more than three million people in northern Taiwan. Construction of the dam began in July 1955 and was inaugurated on June 14, 1964. It has an area of 8 km² (3.09 sq mi) and a capacity of 309,120,000 m³. Its construction forced the displacement of some 2,000 people who lived on the banks of the river. Some 27 km (17 mi) of canals were added to the existing irrigation system, including the new Shihmen Canal (represented in the stamp), which totals 175 km (109 mi).

Rice is a staple food for the inhabitants of Madagascar, which is why it is grown in many places in the north-central part of the country: on terraces in the highlands or on irrigated land in other areas, especially near the coasts. This led to the construction of canals to facilitate irrigation, especially in the east of the island, from the 1950s, during the French colonization.
