Sugarcane, a tall perennial grass, is globally important, extending beyond its primary role as a sugar source to contribute to various industries. It produces roughly 80-85% of the world’s sugar supply and is a feedstock for biofuels like ethanol, particularly in Brazil. Its fibrous residue, known as bagasse, can be used for energy production, paper, and other chemical products. The cultivation and processing of sugarcane provide livelihoods for over 100 million people across approximately 120 countries.
The Origin of Sugarcane
The origins of sugarcane trace back thousands of years to the island of New Guinea and the surrounding islands of Melanesia in Oceania. Scientific evidence suggests that Saccharum officinarum, often referred to as “noble cane,” was first domesticated in this region between 8,000 and 10,000 years ago. Early forms of sugarcane, such as Saccharum robustum, were initially cultivated by the Austronesian and Papuan people, primarily for chewing to extract its sweet juice.
From New Guinea, cultivated sugarcane spread westward through ancient human migration routes. Around 6,000 BP, various strains were selectively bred from the native Saccharum robustum. This early domestication led to the development of varieties optimized for higher sugar content, transforming it from a simple chewed plant into a valuable agricultural crop.
Sugarcane’s Global Journey
Sugarcane’s journey from its native lands began with its spread to Maritime Southeast Asia, where it hybridized with other wild species like Saccharum spontaneum. Austronesian sailors and traders introduced sugarcane to India and Southern China by around 500 BCE, also spreading it eastward to Polynesia, Island Melanesia, and Madagascar in prehistoric times. The earliest known production of crystalline sugar from sugarcane began in northern India, with techniques for crystallization developing around the 5th century CE.
From India, sugarcane cultivation and sugar production techniques spread to Persia between 500 and 600 CE. Arab traders then facilitated its westward expansion, introducing sugar to the Mediterranean, North Africa, and the Iberian Peninsula by the 8th century. Crusaders returning to Europe in the 12th century further popularized sugar, which they encountered in the Holy Land. Christopher Columbus introduced sugarcane to the Americas on his second voyage in 1493, initially to Santo Domingo (Hispaniola). The establishment of sugar plantations in the Caribbean and Brazil during the 16th to 18th centuries relied on enslaved African labor, shaping the region’s history and economies.
Where Sugarcane Grows Today
Today, sugarcane is cultivated across tropical and subtropical regions globally, requiring specific environmental conditions to thrive. It prefers a hot and humid climate with temperatures ranging between 21°C and 32°C for growth. Adequate rainfall, between 1,100 and 1,500 mm annually, is necessary, though irrigation can supplement water needs in drier areas. Sugarcane is a sun-loving plant, needing ample sunlight throughout its growth cycle.
Major sugarcane-producing countries include Brazil, the world’s largest producer, followed by India, Thailand, and China. The United States also cultivates sugarcane in states like Florida, Louisiana, and Texas, primarily in its southern regions. Its versatility in producing sugar, ethanol, and other co-products sustains agricultural economies in many nations.
