Multicolored 'mosaic' of mini farms surrounds Taiwan's largest river — Earth from space

QUICK FACTS Where is it? Yunlin County, Chianan Plain, Taiwan [ 23.78563273, 120.44373747 ] What's in the photo? A multicolored 'mosaic' of small, tightly compacted farms Which satellite took the photo? Landsat 9 When was it taken? April 24, 2026 This recent satellite snap shows off a multicolored "mosaic" of tightly packed mini farms covering part of Taiwan in the western Pacific Ocean.

The sea of fields and shade nets demonstrates the scale of the agricultural challenges facing the densely populated island.

Taiwan is 14,000 square miles (36,000 square kilometers) — about the same size as Maryland — but has a population around four times as large, with approximately 23 million people living there, according to NASA's Earth Observatory .

This places a heavy burden on the island's agricultural industry to provide enough food for everyone on the island, especially as large parts of the landmass are covered by mountains and rainforest.

Researchers estimate that there is only around 3,200 square feet (300 square meters) of Taiwanese farmland per citizen, which is around two-thirds the size of a basketball court, according to the Earth Observatory.

This is around 10 times less than the equivalent for U.S. citizens.

The majority of the island's food is produced within Yunlin County, which is situated around halfway along the Chianan Plain, a lengthy strip of flat terrain that hugs Taiwan's west coast.

Just under half of the county is visible in the satellite image, which spans roughly 15 miles (24 kilometers) across.

The flat ground in Yunlin County, as well as access to water from the island's largest river, the Zhuoshui (visible across the top of the image), makes it an ideal place to grow a variety of different crops, including "rice, sweet potatoes, peanuts, corn, sugarcane, garlic, scallions, coffee, fruit, and leafy greens," Earth Observatory representatives wrote.

The restricted size of Taiwanese farms means that vastly different crops can be grown alongside one another.

As a result, the region looks like a giant patchwork of tens of thousands of irregular cuboids when viewed from above.

The sizes of Taiwanese farms are restricted by longstanding legislation that limits the amount of land any individual can own, according to the Earth Observatory.

Most of the farms are passed down from generation to generation.

While Yunlin County's agricultural mosaic is fairly consistent across this image, two main areas stand out from the rest (see below).
