Analyzing the trends and seasonality of Uganda's food imports from 1996 to 2025

Abstract

This study examined the long-term trends, seasonal patterns, and future projections of food imports in Uganda. The increasing dependence on imported food products has raised concerns regarding food security, trade balance, and the sustainability of domestic agricultural production. The study utilized quarterly food import data covering the study period and applied time-series analytical techniques to assess historical patterns and forecast future import levels. Trend analysis was conducted using the unit root test, while seasonal variations were assessed through seasonality diagnostics. Forecasting was performed using an ARIMA model selected based on its statistical performance and diagnostic adequacy. Model evaluation was conducted using residual diagnostics and forecasting accuracy measures to ensure the reliability of the results. The findings revealed a significant upward trend in Uganda's food imports over the study period, indicating increasing reliance on external food sources. Seasonal fluctuations were absent across quarters, suggesting that import demand does not vary systematically throughout the year. The forecasting results indicated that food imports are likely to continue increasing in the coming years if current patterns persist. Diagnostic tests confirmed that the selected forecasting model adequately captured the underlying characteristics of the data and produced reliable forecasts. The study concludes that Uganda's food import dependence is likely to remain high unless measures are implemented to strengthen domestic agricultural productivity and food value chains. It is recommended that policymakers invest in agricultural modernization, improve storage and processing facilities, enhance market access for farmers, and promote policies that support increased local food production. These interventions could reduce import dependence and contribute to long-term food security and economic stability in Uganda.
