Bangladesh’s floating gardens, built to grow food during flood seasons, could offer a continuous solution for parts of the world which are likely to suffer from flooding because of climate change, a new study has found.

Bangladesh’s floating gardens began hundreds of years ago. The gardens are made from native plants that float in the rivers and operate almost like rafts (筏), rising and falling with the waters. Historically, they were used to continue growing food during rainy seasons when rivers were filled with water.

But as climate change caused floods, the researchers wanted to know whether Bangladesh’s floating gardens could be a continuous farming practice. They interviewed farming families and found strong evidence that floating gardens provide stability, both in the amount of food to feed rural people and in a farming family’s income.

They found that farmers usually use hybrid (杂交植物) seeds, which must be bought each year, to grow different vegetables in the floating gardens. The gardens are also sensitive to pests so farmers end up spending some money on both pesticides (杀虫剂). But even with these expenses, they found, benefits outweighed costs. One farmer told the research team that he earns up to four times as much money from the gardens as from traditional rice fields.

However, before making money, farmers often take out high-interest loans to cover the investment costs. Luckily, there are also lower-interest loans from responsible government or non-governmental organizations, which could ease that burden.
