Chapter-05: Optimal Dairy Farm Size and Rural Household Food Security: An Agro-Economic Perspective

The dairy sector is a vital component of Pakistan's agricultural economy, serving as a key source of income, employment, and nutritional security for rural households, particularly in Punjab, where smallholder farmers produce most of the country's milk. Despite its economic and social contribution, the sector faces low productivity, limited access to improved technologies, weak marketing infrastructure, and inefficient use of farm resources. This chapter reviews the theoretical and empirical literature linking optimal dairy farm size, economic performance, and household food security from an agro-economic perspective, drawing on Production Theory, Economies and Diseconomies of Scale, Optimal Farm Size Theory, Household Production Theory, and the Agricultural Household Model to explain how farm size shapes productivity, technical efficiency, and management decisions. It examines household food security through its four dimensions, availability, accessibility, utilization, and stability, and shows how dairy farming supports income, nutrition, and livelihood resilience. A review of national and international studies finds that, although farm size, profitability, and food security have each been studied, limited research integrates these issues within a single framework for Pakistan, motivating the conceptual framework and research hypotheses proposed here. The chapter provides a foundation for understanding how optimal farm size can strengthen rural livelihoods and inform evidence-based dairy sector policy.
