Floating Gardens Revive Vegetable Farming in Flood Zones

In recent days, interest has soared in Bangladesh’s floating gardens, a centuries-old farming method now drawing attention for its role in resilient food systems. This practice, known locally as baira or dhap, offers an innovative solution for growing vegetables even when farmland is submerged by monsoon floods. Floating gardens are built on floating beds made of water hyacinth, bamboo, and decomposed organic matter. These floating beds stay afloat during flooding and sink slightly as floodwaters recede, creating fertile platforms for planting leafy greens, gourds, eggplants, and herbs. This method—practiced for over 400 years in districts like Gopalganj, Barisal, and Pirojpur—was highlighted today for its importance in sustainable, climate-smart agriculture. Farmers say the benefits are many. First, the floating beds reduce the risk of crop losses during floods. Second, because water hyacinth is often considered a harmful aquatic weed, using it for garden beds helps control its spread. Finally, the organic compost layer keeps soil fertile without synthetic fertilizers, making it both eco-friendly and cost-effective. This traditional practice is gaining new life thanks to technology. NGOs and community groups are now introducing simple sensors to measure moisture levels, and mobile apps to advise farmers on planting times and crop choices. The combination of knowledge and technology enables even smallholders to boost yields and grow vital vegetables year-round. Women farmers, especially, are benefiting. Many families rely on income from small vegetable plots, and floating gardens are providing food and income security during floods. Each garden helps feed households and creates local surplus for markets. International experts also recognize floating gardens as a model for climate adaptation. They support Bangladesh’s resilience and food sovereignty. FAO and other agencies have featured it as a Globally Important Agricultural Heritage System, encouraging other flood-prone countries to consider similar techniques. Local leader Rehana Begum from Gopalganj noted, “Even when water covers everything, our gardens survive. Now with sensors and advice on our phones, we’re growing more and eating better.” Floating gardens show how traditional food systems can merge with simple digital tools to support sustainability, nutrition, and rural livelihoods. As climate impacts grow, this approach may provide a scalable model—combining centuries-old wisdom with modern support for healthier communities.
