This paper considers those sectors of the economy that operate under the same regimes of rewarding private innovators as others, but differ in that they face recurring problems of resistance, as occur in the pharmaceutical and agricultural industries. This recurrence originates in the natural...

In countries where insurance and credit markets are thin or missing, production and consumption risks play a critical role in the choice and use of production inputs and adoption of new farm technologies. In this paper, we investigated impacts of chemical fertilizer and soil and water...

This study adopts the stochastic metafrontier approach to investigate the role of soil conservation in small-scale highland agriculture in Ethiopia. Plot-level stochastic frontiers and metafrontier technology-gap ratios were estimated for three soil-conservation technology groups and a group of...

This study measures the impact of fanya juu bunds (an important soil and water conservation technology and the most popular type of contour bund in east Africa) on the value of crop production in a high-rainfall area in the Ethiopian highlands using cross-sectional multiple plot observations. We...

In the wake of the resource constraints for external farm inputs faced by farmers in developing countries, sustainable agriculture that relies on renewable local or farm resources presents desirable options for enhancing agricultural productivity. In this study, we used plot-level data from the...

Sustainable agricultural practices, in as far as they rely on renewable local or farm resources, present desirable options for enhancing agricultural productivity for resource-constrained farmers in developing countries. In this paper, we used two sets of plot-level data—from a low-rainfall...

Soil degradation is one of the most serious environmental problems in the highlands of Ethiopia. The prevalence of traditional agricultural land use and the absence of appropriate resource management often result in the degradation of natural soil fertility. This has important implications for...

This paper uses data from household- and plot-level surveys conducted in the highlands of the Tigray and Amhara regions of Ethiopia to examine the contribution of sustainable land-management practices to net values of agricultural production in areas with low- and high-agricultural potential. A...

Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing...
