Productivity growth and the role of mechanisation in African agriculture
ABSTRACT This paper compares agricultural productivity growth, specifically, the impact of agricultural mechanisation on total factor productivity and cereal yields, across African countries using contemporaneous and sequential Malmquist index approaches. Contemporaneous approach findings indicate that agricultural productivity grew by 1% annually over 1961–2014, while sequential technology measures show much higher growth of 1.7%. The highest growth rates were experienced since the 2000s due to technical progress. Regression analysis indicates that mechanisation, research and development, weather conditions, and population pressure influence African agricultural productivity. Climate-smart options to sustain crop yields in countries relying heavily on rain-fed agriculture are critical. The transfer of knowledge from countries with high-level productivity might enhance productivity in “laggard” countries.
期刊介绍:
Agrekon publishes scholarly articles that contribute to the existing literature in the domain of Food, Agricultural and Resource Economics as it applies to Southern Africa. The editors of Agrekon therefore invite contributions in this context that provide new insights, either through the problems they address, the methods they employ or the theoretical and practical insights gained from the results. The quarterly journal serves as the official publication of the Agricultural Economics Association of South Africa (AEASA) and is published by Taylor & Francis.
