The impact of climate change on the production of cassava and sweet potato in Indonesia

Abstract

Cassava and sweet potato are important commodities in Indonesia. They have a role as carbohydrate sources and industrial commodities. Climate factors are environmental production factors that are the most difficult to be controlled. However, climate changes that are happening have certainly made the situation worse. Therefore, this study aims to determine the effect of climate change from climatic factors of temperature, humidity, rainfall, rainy days, and solar exposure on cassava and sweet potato production in Indonesia. This study collected climate factor data from the Indonesian Central Statistics Agency and the Central Statistics Agencies of 34 Indonesian provinces. The study concluded that climatic variables such as temperature, humidity, rainfall, rainy days, and solar exposure affect cassava and sweet potato production at 18% and 26%, respectively. The climatic factors simultaneously significantly affect cassava and sweet potato production. The T-test indicates that temperature, humidity, and rainy days significantly negatively affect cassava production. In contrast, rainfall and solar exposure have a positive impact individually on it. On the other hand, the response of sweet potato production to climate change was different. Temperature and humidity have significant negative effects on sweet potato production, while rainfall and solar exposure have considerable positive effects.

“…It promotes photosynthetic activity in sweet potato plants, resulting in sustainable yield (Spore, 2019). Its importance in crop production cannot be relegated because it serves as a medium for food plants conversion for carbohydrates and encourages soil organisms' microbial activities (Sustrisno, 2023).…”

“…Relative humidity was positive and beneficial at 1%, meaning that an increase in relative humidity of 1% will result in an increase in sweet potato output. Relative humidity raises the moisture capacity of sweet potato lands, particularly during dry seasons, leading to greater sweet potato production and a more sustainable output (Sustrisno, 2023). Relative humidity improves water relation in plant formation, leaf growth, photosynthesis, pollination of plants, and economic production.…”
