Nearly a billion people around the world still suffer from hunger and poor nutrition while a billion are overweight or obese. This imbalance highlights the need not only to focus on food production but also to implement successful food policies. Economist Per Pinstrup-Andersen discusses his new book, coauthored with economist Derrill Watson II of the American University of Nigeria. As a comprehensive road map for understanding how governments and markets shape food policies and production, “Food Policy for Developing Countries” addresses the complex challenges—from issues of poverty and climate change to demographic and dietary transitions—for reducing hunger and achieving better human nutrition.
