洪水和山体滑坡。拉尼娜现象增加了发生洪水与山体滑坡的风险，可能会导致更多的人员伤亡和财产损失，同时影响食物的储备。此外，由于水传播疾病的风险较高，健康和营养状况可能也受到影响。拉尼娜天气现象开始于8月或9月，持续到12月，期间天气会更潮湿，印尼某些地区的降雨量通常会大幅增加至三倍。
火山爆发。由于地处环太平洋火山带，印尼有许多活火山，很容易发生火山爆发。
地震。印尼因位于太平洋、欧亚大陆和澳大利亚构造板块边界，易频繁发生地震，包括2004年引发海啸的印度洋地震。从1970年至2015年，印尼经历了97次地震，造成18.1万人死亡，经济损失117亿美元。
干旱。印尼大部分地区都经历长时间的干旱，特别是在西努沙登加拉省和努沙登加拉帝汶岛地区。在厄尔尼诺现象期间，干旱期会对农业和生计造成重大影响。政府在非政府组织（国际或当地）的援助下，以粮食、资金、水和农业援助的形式提供了旱灾救济。印尼东部许多地区从2015年12月开始面临干旱，一直持续到2017年，造成粮食安全无法得到保障的问题。
Floods and landslides. La Nina phenomenon increases the risk of floods and landslides, which may lead to more casualties and property losses, and affect food reserves. In addition, health and nutritional status may also be affected due to the high risk of waterborne diseases. The La Nina weather phenomenon began in August or September and lasted until December. During this period, the weather will be more humid. The rainfall in some parts of Indonesia usually increases significantly to three times.
Volcano eruption. Due to its location in the Pacific Rim volcanic belt, Indonesia has many active volcanoes, which are prone to volcanic eruptions.
Earthquake. Indonesia is prone to frequent earthquakes because it is located at the boundary of the Pacific, Eurasian and Australian tectonic plates, including the Indian Ocean earthquake that triggered the tsunami in 2004. From 1970 to 2015, Indonesia experienced 97 earthquakes, resulting in 181000 deaths and economic losses of US $11.7 billion.
Drought. Most parts of Indonesia have experienced long-term drought, especially in West Nusa Tenggara province and Nusa Tenggara Timor island. During El Ni ñ o, the drought period can have a significant impact on agriculture and livelihoods. The government provided drought relief in the form of food, funds, water and agricultural assistance with the assistance of non-governmental organizations (international or local). Many areas in eastern Indonesia began to face drought in December 2015 and continued until 2017, resulting in the problem of food security.
