The decline in per-capita agricultural production has been reversed somewhat in tropical Africa by the structural adjustment programs which have increased producer prices, liberalized marketing and devalued currencies. But the 300Jo of smallholder farm households which are female-headed will not...

The identification of local soil variability caused by within-field differences of macronutrients and ecological features is of paramount importance for the effectiveness of precision agriculture. We present several spatial statistical and econometric techniques to capture local differences in...

Many mechanized crop producers and agribusinesses are fascinated with precision agriculture technology, but adoption has lagged behind the expectations. Among the reasons for slow adoption of precision agriculture technology is that initial users focused excessively on in-field benefits from...

The type of resource problem amenable to static analysis is distinguished from that requiring dynamic analysis. Possibly due to the apparent complexity of optimal control theory methods, often dynamic models have not been applied where they would be appropriate. In this article dynamic...

This paper advances consideration of the Heckscher-Ohlin (H-0) theory of comparative advantage to agriculture in a dynamic setting. The dynamic relationship among trade flows, resource supplies, and factor contents is studied. The view that special circumstances in the agricultural sector render...

This paper attempts to identify sources of resource use inefficiency for cotton production in Pakistan's Punjab. The use of a non-parametric method, Data Envelopment Analysis (DEA), is developed to study the relative technical and allocative efficiencies of individual farms which use similar...

The 11 genebanks of the Consultative Group on International Agriculture (CGIAR) have grown considerably in size over the past few decades, currently holding about 666,000 accessions of germplasm. Conserving germplasm is a very long run, if not in perpetuity, proposition. The mismatch between the...

This paper examines evidence of the effects of economic liberalization and globalization on rural resource degradation in developing countries. The principal resource effects of concern are processes of land use change leading to forestland conversion, degradation and deforestation. The main...
