Although agriculture is the second-largest sector in the economy, Libya depends on imports in most foods. Climatic conditions and poor soils limit farm output, and domestic food production meets about 25% of demand. Domestic conditions limit output, while income and population growth have increased food consumption.[1] [2] Because of low rainfall, agricultural projects like the Kufra Oasis rely on underground water sources.[1][2] Libya's primary agricultural water source remains the Great Man-made River (GMMR), but significant resources are being invested in desalinization research to meet growing demand. Libyan agricultural projects and policies are overseen by a General Inspector; there is no Ministry of Agriculture, per se.[3]
