      abstract = {Although `Green Revolution' technology is the major  technological breakthrough in agricultural history, which  is adopted by nations worldwide, including Bangladesh, to  boost their foodgrain production, it is increasingly felt  that productivity from this new agricultural technology is  declining and is a threat to sustainability of economic  development. The present study attempted to evaluate the  role of technological change in augmenting aggregate crop  growth and sustaining food production for the future in  Bangladesh. The overall hypothesis is that, though modem  technology diffusion has contributed to crop production  increase, it has not spread uniformly across regions and  the long-run crop production is reaching a saturation  level, thereby, threatening food production sustainability.  Database of the study consists of time-series data for 47  years (1948 - 1994) and regionwise (19 region) data for 29  years (1961 - 1992). Results revealed that technological  change played a significant role in augmenting aggregate  crop productivity. `Constant return to scale' prevails in  the crop sector when only traditional inputs are used while  incorporation of technological and infrastructural factors  revealed `increasing returns to scale'. But, declining  productivity of modem rice, the major vehicle of  technological change, is raising doubts on sustaining food  production. The current increase in food production is  largely due to switching from local to modem rice varieties  and may not be sustainable in the long run. Trend analyses  of 47 years of foodgrain production revealed that  productivity is reaching a saturation value of 2,200 kg/ha,  raising further doubts on food production sustainability to  meet the growing demand. A policy of crop diversification  incorporating non-foodgrain crops (potatoes, vegetables,  spices, and cotton) as a strategy to sustain agricultural  growth is suggested. Also, effective price policy, crop  insurance policies, transportation, marketing, storage,  extension and rural infrastructure development is  suggested.},
