在今后50年及以后，全球粮食安全仍将是全世界关注的问题。最近，由于对研究和基础设施的投资减少，以及水资源日益短缺，许多地区的作物产量下降。气候变化和艾滋病毒/艾滋病也是影响许多地区粮食安全的关键因素。虽然农业生态方法为提高产量提供了一些希望，但发展中国家的粮食安全可以通过增加投资和政策改革得到实质性改善。
Global food security will remain a worldwide concern for the next 50 years and beyond. Recently, crop yield has fallen in many areas because of declining investments in research and infrastructure, as well as increasing water scarcity. Climate change and HIV/AIDS are also crucial factors affecting food security in many regions. Although agroecological approaches offer some promise for improving yields, food security in developing countries could be substantially improved by increased investment and policy reforms.
