When farmers consume much of their grain output, end-use quality, in addition to standard production characteristics, affects farmers' seed choice and the economic returns to investment in crop breeding. Evidence from Malawi suggests that despite a lengthy research lag, emphasizing grain quality...

This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and in what ways genetic resources have contributed to wheat productivity and...

Sources of yield growth in wheat are investigated based on a stylized framework of technical change. Evidence suggests that the relative contribution of input intensification to yield growth has diminished in recent years and is likely to continue to decline in the future. One potential source...

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...

Recent criticisms of the “green revolution” wheats concern the effects of their popularity on crop diversity and the consequences for productivity and conservation. We use a Just-Pope production function to test the relationship of genetic resource and diversity variables to mean and...

Climate change poses significant risks to future crop productivity as temperatures rise, rainfall patterns become more variable, and pest and disease pressures increase. The use of crop genetic resources to develop varieties more tolerant to rapidly changing environmental conditions will be an...
