All along the coast, there were these long, remarkably straight lines running inland from the sea, separated by almost perfectly regular distances. And everywhere I looked, I kept seeing the same word in place names: Parit. What started as a bit of curiosity about a small fishing town turned into an investigation of a massive land reclamation project, the Javanese pioneers who built it, and the history of how Johor transformed its coastline.I set off from my homestay in Muar for a day of cycling around the countryside, trying to figure out what I had been looking at on the satellite images. The answer turned out to be a network of hand-dug canals, earthen dykes called bund, and water gates known as pintu air. Together, these formed an ingenious drainage system designed to turn the wet, acidic peat forests behind the coastal mangroves into productive agricultural land. The more I looked, the more I realized that the landscape I was cycling through was anything but natural. Even the roads I was riding on were often built along the tops of these enormous earthworks.But who would undertake such a monumental job, digging canals through flooded forests and mangrove swamps with nothing but manual labour? That question led me to the Javanese men who migrated from Java to Johor in search of land and a better future. Under the land grant system developed during the reign of Sultan Abu Bakar and his predecessors, people who cleared and drained the land could earn ownership of the land they made suitable for farming. The canals were part of a much bigger effort to modernize Johor, develop its agricultural economy, and preserve its independence in an era of growing British influence.There's an interesting connection to the wider world here, too. One of the important early cash crops was gambier, whose extract was used in tanning leather. As industrialization increased demand for leather goods in Britain, opportunities opened up for plantation agriculture in Southeast Asia. Following that thread led me into questions about migration, land ownership, colonialism, and the surprisingly complicated history behind what might otherwise look like a few ordinary drainage ditches.And of course, this is still Planet Doug, so there are plenty of diversions along the way. I encounter macaques, monitor lizards, and some particularly entertaining mudskippers, explore canals that have become working fishing harbours, and stop for an iced kopi along the coast. Google Maps satellite view turns out to be an especially useful companion, revealing the scale and astonishing regularity of a system that's difficult to appreciate from ground level.
