Gladwin's * * main contention is that women provide most of the agricultural labor in sub-Saharan Africa and because much of this labor is oriented to food production for home consumption, the effects of structural adjustment programs on them and the children they work to feed are likely to be...

An econometric approach using international and national yield trial data is employed to estimate a spillover matrix for wheat varietal technology. The global spillover matrix is estimated based on international yield trial data from 1979-80 to 1987-88, that include 195 international trial...

Estimates of aggregate disease costs can be used for assigning research resources or to evaluate control measures. Most diseases cause production losses, but others affect quality and marketability. Seed-borne diseases also cause problems for the seed production and distribution industry. The...

Cropping intensity in the cotton-wheat areas of Pakistan's Punjab is well below its potential, and also significantly lower than in neighbouring areas of India's Punjab. Analysis of annual cropping intensity indicates that access to irrigation water is the major factor explaining differences in...

We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India's total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers....

Expenditures on agricultural research in the public sector, including the International Agricultural Research Centers (IARCs) have stagnated and in some cases, declined sharply in recent years. This has focused attention on issues of efficiency of agricultural research systems, especially the...

Many economists have advocated and applied total social factor productivity (TSFP) (i.e., total factor productivity estimated with both market and non-market inputs and externalities, and with all factors valued at social prices) as a single all-embracing measure of agricultural sustainability....
