In the contemporary world, achieving sustainable food production has become an urgent task for the international community and policymakers due to the rapidly growing social challenges of mankind. Sustainable food production practices aid countries in adapting to the challenges posed by climate change, thereby ensuring a better and more sustainable future for all. This study examines the impact of land use, energy efficiency (ENE), water productivity (WP), renewable energy consumption (REC), and gross domestic product (GDP) on sustainable food production in G20 nations over the period of 1998–2020. We use quantile regression approaches to capture potential heterogeneity across various food value-added distribution quantiles. The results show that arable land, WP, GDP, ENE, and REC are important factors affecting food value added in G20 nations. However, the nature of the relationship varies across different quantiles, suggesting heterogeneity in the relationships. The results show that ENE, renewable energies, and GDP are positively related to food production. However, arable land and WP are negatively related to food production. The findings can assist policymakers and stakeholders in making informed decisions to increase value added in the agricultural sector while promoting resilience and sustainability.

水、粮食和绿色能源关系的困境：COP27 为 G20 经济体带来的新背景

当今世界，人类面临的社会挑战迅速增多，实现可持续粮食生产已成为国际社会和决策者面临的紧迫任务。可持续粮食生产实践帮助各国适应气候变化带来的挑战，从而确保所有人拥有更美好、更可持续的未来。本研究考察了 1998 年至 2020 年期间土地利用、能源效率 (ENE)、水生产率 (WP)、可再生能源消耗 (REC) 和国内生产总值 (GDP) 对 G20 国家可持续粮食生产的影响。我们使用分位数回归方法来捕获各种食品增值分布分位数之间的潜在异质性。结果表明，耕地、WP、GDP、ENE和REC是影响G20国家食品附加值的重要因素。然而，不同分位数之间关系的性质有所不同，表明关系存在异质性。结果表明，ENE、可再生能源和GDP与粮食生产呈正相关。然而，耕地和WP与粮食产量负相关。研究结果可以帮助政策制定者和利益相关者做出明智的决定，以增加农业部门的附加值，同时提高抵御能力和可持续性。
