These factors combine to create an environment not conducive to cultivation. To make matters worse, in recent years the rainy and dry seasons have become muddled due to the impact of climate change. This in turn has reduced the capability of the soil to hold moisture, precipitating increased salinity. Also, the more frequent and powerful storms have increased the risk of low-lying areas being flooded by seawater.
雪上加霜的是，由於氣候變遷的衝擊，近年雨、旱季節紊亂，導致土壤含水能力降低並加速鹽化；風浪的頻率與威力增強，也增加了低窪地區遭海水淹覆的風險。
