洪水。季风季来临时，暴雨过后柬埔寨经常骤发洪水，袭击马德望、磅清扬、磅士卑、磅礴、贡布、坎达尔、普尔萨特和拉塔那基里等省份。柬埔寨还会受到洞里萨河和湄公河支流泛滥引起的缓慢但长期的洪水的影响，该洪水会淹没磅湛、桔井、坎达尔、波罗勉、上丁、斯维京和茶胶等省份。
干旱。预期降雨提前结束或推迟到来引起的水资源短缺是柬埔寨干旱的主要原因。目前只有20%覆盖率的灌溉设施又进一步恶化，大大降低了完全依靠雨水或河水灌溉的水稻种植群体的农业生产力。
台风。东亚和太平洋地区每年平均有27场台风。一些到达东南亚地区的台风和热带低气压在陆地上空并未减弱，使得柬埔寨境内暴雨和大洪水肆虐。
滥伐森林。柬埔寨约46%的国土面积被森林覆盖，生物种类丰富。它是东南亚第三大低地干常绿森林，有2300种植物、14种濒危动物和世界上仅存的7条大象走廊之一。柬埔寨的森林和生物多样性面临许多威胁，这些威胁包括清除和退化、过度开发关键物种和对碳固存等生态服务的低估。随着农业工业化和采矿业的发展，森林数量不断减少。柬埔寨是世界森林砍伐速度最快的国家之一，森林覆盖率从2006年的60%降到了2014年的47%。
flood. When the monsoon season comes, Cambodia often has sudden floods after heavy rains, which attack Battambang, Kompong Ching Yang, Kompong SPEU, Kompong, Kampot, Kandal, Pursat and Ratanakiri provinces. Cambodia will also be affected by slow but long-term floods caused by the flooding of Tonle Sap River and Mekong tributaries, which will inundate provinces such as kampong Cham, Kratie, Kandal, boroveng, stung treng, svigin and Chajiao.
Drought. The shortage of water resources caused by the expected end or delay of rainfall is the main cause of drought in Cambodia. At present, the irrigation facilities with only 20% coverage have further deteriorated, greatly reducing the agricultural productivity of rice planting groups that rely solely on rainwater or river water irrigation.
typhoon. There are an average of 27 typhoons in East Asia and the Pacific every year. Some typhoons and tropical depression reaching Southeast Asia have not weakened over the land, causing rainstorms and floods in Cambodia.
Deforestation. About 46% of Cambodia's land area is covered with forests and is rich in biological species. It is the third largest lowland dry evergreen forest in Southeast Asia, with 2300 species of plants, 14 species of endangered animals and one of the only seven elephant corridors in the world. Cambodia's forests and biodiversity face many threats, including removal and degradation, overexploitation of key species and underestimation of ecological services such as carbon sequestration. With the development of agricultural industrialization and mining, the number of forests is decreasing. Cambodia is one of the countries with the fastest deforestation rate in the world, and the forest coverage rate decreased from 60% in 2006 to 47% in 2014.
