As the global population accelerates towards nearly 10 billion by mid-century, the imperative to transform food production systems has never been more urgent. Conventional agriculture, long regarded as the backbone of global food security, is increasingly strained by climate change, water scarcity, and land degradation. These challenges compel scientists, policymakers, and innovators to investigate alternative food sources that not only meet nutritional demands but also align with sustainability goals.
Together, these alternative food sources and innovative cultivation techniques constitute a multifaceted approach to meeting global food security within planetary boundaries. Each method—whether entomophagy, seaweed farming, plant-based meats, cultured meat, aquaculture advancements, neglected crops, or hydroponics—addresses unique dimensions of sustainability, nutrition, and cultural acceptance.
