Advances in Soil Science: Dryland Agriculture: Strategies for Sustainability Volume 13 - Advances in Soil Science

From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. The world's irrigated land in 1950 totaled 94 million hectares but increased to 140 million by 1960, to 198 million by 1970, and to 271 million hectares in 1985.
