Book Description
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 (as opposed to the later intensification and post-Green Revolution periods) 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 estimates, 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. These findings imply the need for policies that promote agricultural productivity and sustainability through public investments in education, roads, and research and extension; and that reduce resource degradation by decreasing or eliminating subsidies that encourage intensification of inputs.

Book Description
This book challenges the assumption that the major benefits of investment in rural education accrue to traditional agricultural activities, such as staples production.

Book Description
This title was first published in 2003. he public sector plays a dominant international role in the provision of agricultural extension and services. This role has been the subject of much debate. Some argue for extension's privatization, claiming that a market driven system provides the most rational and efficient means of information delivery. Based on extensive empirical research from the Punjab (Pakistan), this volume examines the comparative effectiveness of public and private extension services from the perspective of farmers. It also focuses on information from extension agents about their respective organizations and work environments. In so doing, the book expands and elaborates on the practical considerations of privatization and information delivery. It then broadens out into a discussion of alternative means of extension delivery, focusing on participatory approaches, education theory and pluralism.
