In a recent report, the United States Department of Agriculture Economic Research Service (USDA ERS) has unveiled projections outlining the escalating demand for crop calories to sustain the global population in 2050.
The study, categorized by varying population growth scenarios, highlights the imperative need for a substantial increase in food production to meet the nutritional requirements of an expanding world.
Under a low population growth scenario, with a projected global population of 8.73 billion by 2050, ERS researchers anticipate a 33% surge in food production, reaching 12,740 trillion crop calories from a 2011 baseline.
The stakes rise under a medium population growth scenario, envisioning a population of 9.75 billion, where a 47% increase to 14,060 trillion crop calories is deemed necessary. In the most challenging scenario, with a high population growth projection of 10.8 billion, the USDA projects a staggering 61% rise to 15,410 trillion crop calories.
Crop calories, defined as the total calories available from crops, serve as a fundamental measure of global agricultural capacity. Whether directly consumed or utilized in the production of meat, dairy products, and eggs, these calories are crucial for sustaining an increasingly affluent and growing global population.
The caloric estimates factor in rising per capita incomes worldwide, suggesting that as incomes increase, people are likely to augment both their overall daily calorie intake and their consumption of animal products.
As the world grapples with the complex challenge of feeding an ever-expanding population, these projections underscore the pressing need for strategic and sustainable approaches to global agriculture in the coming decades.
