Summary: | This article attempts to determine the
long-term productivity and sustainability of irrigated
agriculture in the Indian and Pakistan Punjabs by measuring
trends in total factor productivity for production systems
in both states since the advent of the green revolution.
These measurements over time and across systems have
resulted in three major findings. First, there were wide
spatial and temporal variations between the two Punjabs.
Although output growth and crop yields were much higher in
the Indian Punjab, productivity growth was higher by only a
small margin. Moreover, the lowest growth in productivity
took place during the initial green revolution period and in
the wheat-rice system in both states. The time lag between
adoption of green revolution technologies and realization of
productivity gains is related to learning induced efficiency
gains, better utilization of capital investments over time,
and problems with the standard methods of productivity
measurement that downwardly bias estimate, particularly
during the green revolution period. Second, input growth
accounted for most of the output growth in both Punjabs
during the period under study. Third, intensification,
especially in the wheat-rice system, resulted in resource
degradation in both Punjabs. Data from Pakistan show that
resource degradation reduced overall productivity growth
from technical change and from education and infrastructure
investment by one-third. |
