Introduction
In Romania, adopting a plant-based diet could have a profound impact on agricultural land use, reflecting broader global trends. This study investigates the potential land savings by analyzing the land required to produce various sources of calories. The focus is on understanding how a shift in dietary habits could contribute to more sustainable land use, environmental conservation, and the achievement of Sustainable Development Goal (SDG) 12, which aims to ensure sustainable consumption and production patterns.
Methods
The research employs data from governmental sources (Romanian Ministry of Agriculture), and international reports from organizations (FAO). It examines the land-use efficiency of different foods, comparing meat, dairy, grains, and legumes. The analysis involves calculating the land required per calorie produced and extrapolating these findings to model the impact of a nationwide dietary shift.
Results
Preliminary findings indicate that plant-based foods, such as grains and legumes, require significantly less land per calorie compared to animal-based products. For example, producing one calorie from beef requires substantially more land than producing the same amount of calories from beans. If Romania's adult population transitioned to a plant-based diet, the potential reduction in agricultural land use could be as high as 75%. This transition would not only free up land for other uses but also reduce the pressure on natural ecosystems and lower greenhouse gas emissions from agricultural activities.
Conclusions
Transitioning to a plant-based diet among Romania's adult population presents an opportunity for substantial agricultural land savings and environmental benefits. Such a dietary shift would support the conservation of natural resources and contribute to national and global sustainability goals. Moreover, the proposed model can be applied to other countries, providing a scalable solution to reduce agricultural land use worldwide. Efforts must coordinate to educate the public on plant-based diet benefits and develop policies for sustainable agriculture.
