| Adverse environmental effects of international trade are emphasized in the literature frequently. Nevertheless, following a theoretical trade logic, the production of goods in regions with higher resource efficiency may lead to reduced global resource use. In this article, major drivers of food-related material footprint (MF) are analyzed at the global, regional, and country levels. Changes in consumption, the supply chain's efficiency, and participation in international trade are considered drivers of MF. An index decomposition analysis was conducted to assess the contribution of these factors to the variation of the MF in time. Our results partially prove that the optimization regarding natural resource use may contribute to a lower MF of food consumption. Regions and countries with increasing food imports reinforce their efficiency improvement with the lower resource intensity of imported goods, and the international trade counteracted the effects on additional resource requirements of increasing consumption throughout the analyzed period (1990-2013). Furthermore, the impact of international trade on capital stock is discussed. In line with the descending flow-type material intensity by approximately 5%, the material composition of the footprint has shifted toward stock building materials. Additionally, the intensity of the trade was found to be negatively correlated with domestic efficiency improvements. |
