孟加拉国帕德玛大桥建设项目即将完工(1)。这座大桥长6.15公里，耗资近40亿美元(2)，将连接该国北部和东部与西南部的库尔纳(Khulna)，其中包括孙德尔本斯(Sundarbans)--世界上最大的红树林，在孟加拉国和印度绵延1万平方公里(3)。这座大桥投入使用后，预计将使孟加拉国的国内生产总值增加1.2%(4)，但它也将危及脆弱的孙德尔本斯红树林生态系统。由于商业上有利可图的对虾养殖业的兴起，孟加拉国已经失去了南亚和东南亚最古老的红树林之一查卡里亚桑德尔本斯(Chakaria Sundarbans)。同样的情况也可能发生在库尔纳地区，那里的大桥建设加剧了不断上涨的地价，并扩大了孙德尔本斯附近的房地产、渔业、旅游业和度假村的开发(6)。这座大桥还将方便人们更好地进入繁忙的蒙拉港，并可能加快该地区的森林砍伐和土地掠夺。
The Padma Bridge construction project in Bangladesh is near completion (1). The 6.15-km-long bridge, costing nearly US $4 billion (2), will connect the northern and eastern parts of the country to the southwest Khulna division, which includes the Sundarbans—the world’s largest mangrove forest stretching over 10,000 km2 in Bangladesh and India (3). The bridge, when commissioned, is expected to boost Bangladesh’s gross domestic product by as much as 1.2%(4), but it will also put the fragile Sundarbans mangrove ecosystem at risk.Bangladesh has already lost the Chakaria Sundarbans, one of the oldest mangrove forests in South and Southeast Asia, as a result of the rise of commercially profitable shrimp farming (5). The same could happen in the Khulna division, where the bridge construction has exacerbated increasing land prices and expanding development of real estate, fisheries, tourism, and resorts near the Sundarbans (6). The bridge will also facilitate greater access to the busy Mongla Port and likely accelerate forest clearing and land grabbing in the area.
