"Land-Efficient Allocation of Agricultural Production Under Alternative Trade Regimes: Implications for Global Land-Use Change and Biodiversity" Authors: Totake, Ryo, Tomoko Hasegawa, Kazuaki Tsuchiya and Shinichiro Fujimori Abstract Agricultural expansion is a major driver of global biodiversity loss, yet future food demand is expected to continue increasing. Because land productivity varies widely across regions, the spatial allocation of agricultural production may strongly influence how much land is required to meet that demand. International trade shapes this allocation, but it remains unclear whether alternative trade regimes can reduce land-use pressure and biodiversity loss. We evaluated how alternative future trade regimes affect global agricultural production, land use, and biodiversity under a baseline, uniform liberalization, uniform protectionism, and a productivity-oriented regime that favors production in relatively land-efficient locations. Uniform trade liberalization increased trade and production, but also expanded cropland and lowered global crop land productivity, indicating a shift towards less land-efficient production. Protectionism did not provide a clear biodiversity benefit. By contrast, the productivity-oriented regime increased global land productivity, reduced agricultural land demand, and alleviated biodiversity loss. These results show that the environmental effects of trade depend not simply on trade openness, but on how alternative trade regimes shape the geography of production. Trade frameworks that better align production with land productivity could help reduce the land required to meet future food demand and thereby limit biodiversity loss. More broadly, the findings suggest that international trade regimes may be an important, but underexplored, component of strategies to reconcile food production with biodiversity conservation. |
