Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. The innovations of the present paper are estimates of monthly (i.e. seasonal) versus annual global acreage response models f...
Impact of Rural Road Improvement on High Yield Variety Technology Adoption: Evidence from Bangladesh
Rural road improvement that enhances access to input and output markets and agricultural extension services may aid agricultural technology adoption. There is a growing body of literature on the impact of rural roads on technology adoption. However, most studies have so far relied on cross-sectional surveys comparing households with and without road improvement, which have causal attribution pr...

The recent developments of remote sensing technology, in particular with its improved spatial and temporal resolution, open new possibilities for estimating crop acreage over larger areas. Remotely sensed data allow the estimation of crop acreage independently of sometimes biased and incomplete sub-national survey statistics. This paper presents a methodology on crop acreage estimations using t...
Privately owned forests, wetlands, and crop-lands in the United States are disappearing at alarming rates due to development and erosion , according to a report released by the U.S. Department of Agriculture (USDA) on 7 December 1999. The report, which summarizes the USDA's 1997 National Resources Inventory (NRI), reveals that development has doubled during the last decade to-more than three mi...
introduction in recent years due to problems associated with intensive agricultural systems, the role of legumes in the sustainability of cropping systems has been accelerated (draper, 2006). currently, one of the challenges of energy intensive agricultural systems is monoculture, which is associated with low biological diversity (carmine, 2007). iran has been considered as the area with low ag...
This study analyzes the potential impacts of expanded ethanol production on southern agriculture. Results of regression analysis suggest that acreage planted for field crops (corn, cotton, soybeans, and wheat) is inelastic with respect to relative prices. The results provide statistical evidence of potential significant acreage shifts favoring corn over cotton, soybeans, and wheat. Simulations ...
Background: To mitigate climate impacts associated with energy consumption, renewable fuel policies have been established in the USA that encourage production and use of corn ethanol. Current fuel usage of corn ethanol is approximately 15 billion gallons/year (57 billion liters/year), with nearly all of this in the form of E10 (10% blend in gasoline). There is now interest in increasing fuel et...
