“…1 ). Today, despite its relatively small contribution to gross domestic product, U.S. agriculture has accounted for 15% of total U.S. productivity growth since 1960 ( 32 ), and at times, agricultural productivity growth has averaged almost 10 times the economy-wide productivity growth rate. In addition, major structural transformations are still underway ( Fig.…”

“…Innovations have been an important part of the process of economic development. Technological progress is a major contributor to productivity improvements and income growth (Jorgenson 2011). This can be seen in agriculture (Mundlak 2000;Pardey, Alston, and Ruttan 2010;Fuglie and Wang 2012).…”

Adoption of agricultural innovations has been an important factor affecting the welfare of farmers, the productivity of agriculture and the economics of the food sector. This paper reviews the literature on technology adoption in agriculture with a focus on the role of uncertainty and learning. It examines the factors affecting adoption benefits for farmers and their linkages with the innovation process. It also discusses the welfare implications of innovation and adoption for farmers and consumers.

“…Many neoclassical economists, other technology supporters and some empiricists [18][19][20] argue that technological advancements will allow indefinite growth in agricultural productivity. They postulate that new technology [such as Genetically Modified Organisms (GMOs) or better irrigation systems] will make crop production yields higher and also more efficient.…”

Efficiency of Edible Agriculture in Canada and the U.S. Over the Past Three and Four Decades

Abstract:We examine technological progress in the US and Canada to answer the question: has the efficiency (e.g., the edible energy efficiency, or EEE) for producing agricultural products in the US and Canada increased in recent decades? Specifically, we determined the energy efficiency of agriculture at the farm gate in recent decades by dividing the outputs (the total annual crop and animal output in energy units minus the feed used for animal production and the grain used for ethanol production) by the energy inputs: all the energy used by the nation to produce food (the energy used to generate and apply the fertilizer, pesticides, seed and to operate machinery) minus the energy inputs to produce grain for ethanol. Our data comes primarily from national and international agricultural censuses. Our study found that the energy efficiency of US agriculture has more than doubled from 0.8:1 in 1970 to 2.2:1 by 2000, then increased more slowly to 2.3:1 by 2009. The energy efficiency of the agricultural sector in Canada has not changed appreciably since 1980, and has varied about a mean of 2:1 from 1981 to 2009. Our study found that EEE improvements in the US could be attributable in part to advancements in crop production per hectare, and lower direct fuel consumption, but also a greater proportion of less energy-intensive corn and changes to the diet of livestock (e.g., increased use of meals and other by-products which have increased the availability of grain). Thus increases due to technological progress alone for the last several decades appear small, less than one percent a year.
