“Nothing escapes geography.”

Founded in 1955, Geographical, Geological & Archaeological Society SSS HKUSU (“GGAS”, formerly Geographical, Geological & Archaeological Society AA HKUSU) has been one of the oldest societies in continuous operation in the University of Hong Kong. Despite having gone through some challenging times in the past half-century, the Society’s goal to serve Members to the highest standards has never been wavered, and shall remain immutable for the foreseeable future. The transition in affiliation from Arts Association HKUSU to Social Sciences Society HKUSU in 2008 embodies a new beginning for the Society to thrive again and reach new zenith. At GGAS, we believe that zeal is the key to success. As inscribed in the Society’s constitution, the Society not only aims to cultivate Members’ interests and knowledge in Geography, Geology and Archaeology, but we are also committed to developing social awareness among our Members, especially social issues that are related to Geography, Geology and Archaeology. Our zeal is inherent in everything we do, from publishing news bulletin to organizing large-scale events such as the Orientation Series. It is this spirit that keeps us together, that empowers us to serve our Members, and to care for the community.

第31期 地紙 《被海追趕的國度 —— 圖瓦盧的氣候命運》

引言

氣候變化無疑是二十一世紀廣泛討論的環境議題之一。隨著海平面持續上升,許多低窪地區正面臨被淹沒的風險。國土沉沒並消失在海洋之下,已不再是天方夜譚,而是迫在眉睫的現實。

圖瓦盧(Tuvalu)是嚴重受氣候變化威脅的南太平洋島國。它位於國際換日線以西,在南緯 5° 至 10° 與東經 176° 至 180° 之間。作為全球第四小及大洋洲第二小的國家,圖瓦盧的陸地面積僅有約 26 平方公里(香港島面積為約 81 平方公里)。地形上,圖瓦盧由三座礁島與六個環礁,共計九個島嶼組成。

圖瓦盧平均海拔不足海平面上 5 米,使其極易受風暴潮、漲潮與洪水等現象的侵襲。依照目前海平面的上升速度,海平面預計將於 2100 年上升近 1 米,令這個國家處境如履薄冰,瀕臨被淹沒邊緣。即便有研究指出在 40 年間,圖瓦盧陸地因礁砂堆積增加 2.9%(0.735 平方公里),但這距離能抵消氣候變化帶來的威脅仍是望塵莫及。

地理特徵及其脆弱性

地形
圖瓦盧平均海拔不足 5 米,因而在極端天氣下常暴露於漲潮、風暴潮與海岸侵蝕。研究指出,在本世紀中期前,最高潮位可能淹沒圖瓦盧首都兼人口最多的島嶼 —— 富納富提(Funafuti)高達 50% 的面積。嚴重的海岸侵蝕亦導致潔白無瑕的沙灘每年縮減約 1% 至 2% 的面積。自 1993 年以來,海平面已上升約 0.15 米,而目前的上升速度已加速至每年 5–7 毫米。若全球減排成效不彰,圖瓦盧到 2100 年將可能失去 95% 的陸地面積。

水資源
在完全被海水吞沒前,圖瓦盧珍貴的水資源已被上升的海洋不斷侵蝕,對居民生活造成前所未有的壓力。圖瓦盧沒有河流或天然湖泊,因此,居民唯有依賴漂浮於鹽水之上的地下淡水層(即所謂的「淡水透鏡」)。可惜好景不常,這些淡水層正隨著海平面上升而縮小,海水滲入亦使不少淡水來源不宜飲用。加上旱災頻仍,圖瓦盧人民正面臨氣候變化所造成的嚴峻缺水與農作物失收問題。

土壤
圖瓦盧大部分地區,包括富納富提,都是由狹長的珊瑚環礁構成,因此,土壤多為多孔、缺乏養分的磷酸鹽砂質土壤。貧瘠的土壤僅能支撐以沼澤芋(pulaka)與椰子為主的農業。然而,這類單一耕作系統在颶風侵襲時極為脆弱。亦有研究發現自 1971 年起,由於侵蝕及大規模採礁,富納富提的沙洲已流失約 5%,使這個岌岌可危的國家更易遭受淹沒威脅。

下沉成因

圖瓦盧主要受地理、環境及人為因素相互影響而面臨被淹沒的風險,海洋動力更是進一步令情況惡化。全球暖化導致海水熱膨脹及冰川融化,從而推動海平面上升。在拉尼娜現象發生期間,增強的信風會把暖水推向西太平洋,令圖瓦盧附近的海平面上升。日益強烈的颶風及風暴潮侵蝕珊瑚礁和海岸線,帶走沉積物並削弱天然屏障。另外,板塊活動和地下水開採導致地陷,令島嶼進一步下沉。海岸開發及人口壓力則進一步亦加劇對生態系統的破壞,在如此脆弱的環礁環境中,即使是輕微的變化,也可能引發嚴重後果。
