Abstract

The agricultural sector plays a fundamental role in accelerating economic growth, ensuring food security, and improving environmental quality in both developed and developing countries. In this respect, increased agricultural productivity is crucial for ensuring food security and supporting economic development. The impact of agricultural productivity on environmental quality is addressed in the literature within the framework of two main hypotheses. The Borloug hypothesis argues that increased agricultural productivity can improve environmental quality, while the Jevons hypothesis argues that increased productivity can worsen environmental quality. In this study, the interaction between increased agricultural productivity and the environment for the US economy, one of the leading agricultural countries, was examined for the period 1990-2022. The ecological footprint variable was used to represent environmental quality. The long-term relationship between the variables was examined using the RALS ADL cointegration technique, taking into account the unit root analysis results, and the existence of a long-term relationship was found. The coefficient estimator findings showed that the effect of total agricultural factor productivity on the ecological footprint was statistically significant and negative. Similarly, the increase in renewable energy consumption was found to have a negative impact on the ecological footprint, while the impact of economic growth was found to be positive. These findings, in the US example, support the Borlaug Hypothesis by showing that increased agricultural productivity can have positive effects on environmental quality, thus highlighting the importance of sustainable agricultural policies.
