Food and agricultural economics examines how farming resources and outputs are allocated, distributed, and utilized, and how these processes influence food availability and economic development. A consistent agricultural surplus is fundamental to growth, as it not only sustains populations but also frees resources for industrialization and technological progress. In many low-income countries, a large share of the population relies on agriculture for survival, not because farming inherently causes poverty, but because limited economic opportunities leave people dependent on it. As incomes rise, however, the relative importance of food and agriculture in the economy declines, a trend explained by Engel’s Law: when income increases, households spend proportionally less on food, even if total spending on food grows. This shift allows fewer resources to meet food demand, enabling labor and capital to move into other sectors. Historically, early economists feared that limited farmland and the law of diminishing returns would restrict food supply as populations expanded, but they underestimated the impact of technological progress, scientific innovation, and improved production methods in both agriculture and related industries. These advances transformed global food systems, ensuring that agricultural economics remains central to understanding how societies balance food security, resource use, and economic development.
