<![CDATA[Population growth influences food (rice) and clean water demand, particularly in Penajam Paser Utara Regency as a buffer zone of the Nusantara Capital City (IKN). This study aims to analyze population projections, food (rice) demand, and clean water requirements in the buffer area of the Nusantara Capital CIty in North Penajam Paser Regency by 2044. The research employs a descriptive quantitative approach using a literature review and secondary data projection analysis based on an exponential model. The results indicate that population size, food (rice) demand, and clean water requirements are projected to increase significantly, reaching 348,141 inhabitants. In line with this trend, rice demand is projected to reach 39,507 tons per year, while clean water demand is estimated at 8,895,002,782 liters per year. Consequently, the development of the Nusantara Capital City is likely to intensify food (rice) and clean water demand. This condition underscores the need for sustainable resource management strategies.]]>
