The forecast for agricultural groundwater abstraction in South Korea indicates a downward trend in usage from 2013 to 2028, with significant fluctuations observed particularly between 2016 and 2018. In 2023, the abstraction volume stood at 1.56 billion cubic meters. Year-on-year variations have shown substantial declines from 2016 onwards, notably a 17.02% drop in 2017 and a 15.14% decrease in 2018. Over the last two years, a slight decline was observed with a year-on-year reduction of 1.33% in 2023.

Looking forward, the forecasted five-year CAGR from 2024 to 2028 stands at -0.94%, predicting further declines in groundwater abstraction.

Future trends to watch for include:

Possible implementation of more stringent water management policies.
Technological advancements in irrigation that could reduce groundwater dependency.
Environmental factors such as climate change impacting water availability and usage.
