INTRODUCTION Rural Road connectivity is a key component of rural development, since it promotes access to economic and social services, thereby generating increased agricultural productivity, non-agriculture employment as well as non-agricultural productivity, which in turn expands rural growth opportunities and real income through which poverty can be reduced. A study (Fan et al. 1999) carried...

The spatial concentration of ideas is central to economic geography. Yet, how proximity to research affects productivity is not well studied. We use the late 19th century establishment of agricultural experiment stations in the United States to estimate the importance of proximity to research for productivity growth. Our analysis of county-level agricultural census data from 1870 to 2000 reveal...

Soil degradation and salinization are two of the utmost threat affecting agricultural areas, derived from the increasing use of low quality water and inappropriate cultural practices. The problem of low productivity of saline soils may be ascribed not only to their salt toxicity or damage caused by excess amounts of soluble salts but also arising from the lack of organic matter and available mi...

This paper analyses determinants of agricultural land prices in Sweden with a particular focus on location-specific factors. An asset-pricing model is used to decompose agricultural land prices into expected returns from land in its current agricultural use and expected returns from its potential use. The model is estimated in a cross regional context where explanatory factors relate to regiona...

This article investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favoured production environments of a developing agricultural economy. Drawing production data from household and plot surveys conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land deg...

Economic theories show that the direction and magnitude of the fluctuations of economic variables depend on the type and magnitude of the shocks they are faced with. Various reasons are noted for fluctuations in demands for imports, including productivity shocks. Accordingly, this research was aimed at identifying the effects of Total Factor Productivity (TFP) shocks of the agricultural sector ...

A linear programming technique is used to decompose agricultural total factor productivity change in China’s provinces during the period 1985 to 1994. The method allows the decomposition of productivity growth into two mutually exclusive and exhaustive parts: technological change and changes in pure technical efficiency. The decomposition provides a natural way to differentiate innovations from...

introduction: the growth of agricultural production and natural resources are from primary objectives of any political system, because this section has a vital role in providing food security. according to the production theories, production growth will come from two sources; more use of production factors within the framework of existing technologies and second, with using more advanced and mo...
