In Bangladesh's southwest coastal region, increasing soil salinity and frequent flooding—exacerbated by climate change—have made traditional agriculture unsustainable. Around 40 million people in Bangladesh live in coastal areas vulnerable to salinity intrusion, with projections suggesting a 26% loss of arable land by 2050 due to salinization (World Bank, 2021). As a result, farmers face declining crop yields, food insecurity, and loss of livelihood. Floating agriculture has been used as an adaptive method, but existing models are limited to small-scale vegetable farming and fail to address the salinity issue effectively. Our solution targets the intersection of climate-induced soil salinity and flood resilience. In our pilot community, Greenland Slum, Khulna, over 65% of families reported difficulty cultivating staple crops like paddy due to high salinity and seasonal submersion. Globally, more than 1 million hectares of land are salt-affected, impacting food security for millions (FAO, 2020). The problem is urgent and growing, especially for coastal, climate-vulnerable populations. Our model addresses this gap by modifying floating beds to support staple crops while naturally reducing salinity using halophytes and absorbent materials—offering a scalable, nature-based solution that can transform struggling farming communities into resilient, self-sufficient ecosystems.

You know, in the coastal areas of Bangladesh, things aren’t looking too great. Salinity’s rising, floods keep coming, and farmers are struggling. It's a mess. But then we came up with something different. Project Harvesting Resilience—it’s a floating bed system, but not just for vegetables. We’ve cracked the code to grow paddy and wheat on water. Yeah, big crops. Not the small stuff you usually see. Here’s the twist. These floating beds aren’t just beds. They’re designed with halophytes. Salt-tolerant plants that suck out all the bad salinity. They clean the water. And guess what? After they do their job, we eat them. Halophytes turn into veggies—sold in local markets, adding value. Waste? Zero. We use everything. These beds? They last about 10–12 years. Built tough for floods. Simple materials. Made to last. And the results? In Greenland Slum, Khulna, farmers are seeing better crops, year after year. More food, less salt. It’s real. And the community? They’re all in, helping shape it. This is more than just a project. It’s a revolution. A sustainable, resilient, and profitable one.

Our solution serves coastal farming communities in Bangladesh, particularly those in climate-vulnerable areas like Greenland Slum, Khulna. These communities are primarily dependent on agriculture for their livelihoods. However, rising salinity and frequent flooding, worsened by climate change, have made traditional farming nearly impossible. Over 40 million people in coastal Bangladesh are facing land degradation, with many losing their source of income and food security. Right now, they’re underserved by existing agricultural practices that fail to cope with changing environmental conditions. Traditional floating beds only support small vegetables, leaving larger crops like rice and wheat out of the equation. Additionally, the materials used in farming are often expensive and not sustainable in the long run. Our solution directly impacts these communities by providing a durable, scalable farming method that grows staple crops in flooded, saline-prone areas. With our floating beds, farmers can cultivate larger crops while reducing soil salinity. They can also harvest and sell halophytes as vegetables, adding extra income. It’s low-cost, environmentally sustainable, and gives farmers a long-term solution to their challenges. Food security is restored, incomes are boosted, and communities regain their resilience against floods and salinity.
