Seaweeds are primary producers and among the important marine ecosystem engineers capable of modifying their surrounding abiotic and biotic environments. The southern coast of Bangladesh has an excellent prospect for seaweeds farming due to favorable environmental conditions and natural availability of commercially important species. Through quantitative and qualitative analyses, the present study determines potential contribution of seaweeds toward achieving several targets of United Nations sustainable development goals (SDGs) and the blue economic development in Bangladesh. There are 300 households engaged in seaweeds farming, primarily along the southeast coast, producing 390 tonnes wet weight (= 97.5 tonnes dry weight) of seaweeds per annum with potential applications in food, feed, cosmetics and pharmaceuticals sectors. And the current seaweeds production can be increased yearly at ~50% rate, which is 50 million tonnes (dry weight) from ~5,000 km² farming area when extrapolated to the year 2050. This may bring a positive change to issues regarding food security, gender equality, economic growth, nutrients removal, carbon sequestration, employment and aquatic environmental health. Overall, the benefits of seaweeds farming could reflect on 26 targets of 8 SDGs and potentially contribute US$0.7 million to the blue economy in Bangladesh.

海藻是主要生产者，也是重要的海洋生态系统工程师之一，能够改变其周围的非生物和生物环境。由于有利的环境条件和商业上重要物种的自然可获得性，孟加拉国南部海岸的海藻养殖前景极佳。通过定量和定性分析，本研究确定了海藻对实现联合国可持续发展目标（SDG）和孟加拉国蓝色经济发展的若干目标的潜在贡献。主要在东南沿海，有300户从事海藻养殖的家庭，每年生产390吨湿重（= 97.5吨干重）的海藻，并有可能在食品，饲料，化妆品和药品领域得到应用。²到2050年的耕作面积。这可能对粮食安全，性别平等，经济增长，养分去除，碳固存，就业和水生环境健康等问题带来积极变化。总体而言，海藻养殖的收益可反映8个可持续发展目标的26个目标，并可能为孟加拉国的蓝色经济贡献70万美元。
