This study examines the effects of land tenure systems on resource-use productivity and efficiency in the Upper East region of Ghana with data drawn from the Ghana Agricultural Production Survey. A stochastic frontier model is employed to analyse resource-use productivity and efficiency of the rice farms.

This research advances the hypothesis that natural land productivity in the past, and its effect on the desirable level of cooperation in the agricultural sector, had a persistent effect on the evolution of social capital, the process of industrialization and comparative economic development across the globe.

The widespread acquisition of land for large-scale/commercial production of biofuel crops in Ghana has raised concerns from civil society organizations, local communities and other parties, regarding the impact of these investments on local livelihoods. This paper assessed the effect of large-scale acquisition of land for production of Jatropha curcas on farmers’ livelihoods in Ghana.

Although many contemporary studies of agriculture associate larger properties with higher relative productivity, this assumption has limited relevancy for the analysis of situations in which property owners profit more from large-scale property accumulation itself rather than any superiority in exploitation opportunities offered by increased size.

The paper uses three years of household farm plot panel data (2006-2009), covering six districts in central and southern Malawi to assess factor productivity and farming system development under the input subsidy program. All farm plots of the households were measured with GPS.

This study analyzes how market imperfections affect land productivity in a degraded low-potential cereal- livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity-consistent covariance matrix estimator.
