An alternative speci¢cation for the trend component of crop yield growth is developed and applied to maize yield data for Zimbabwe's large-scale farming sector. This accounts for permanent regime shifts as new technologies are discovered but allows gradual absorption as adoption follows a di¡usion path. Econometric methods are used to estimate the timing and importance of innovations, as well a...

We develop a simulation model of world crop markets that is based upon Ricardian comparative advantage. We apply the model to twenty-three countries and provide measures of the degree of globalization in this sector, the gains from trade, and the elasticity of trade volumes to trade costs. The distribution of the gains from trade across countries is uneven due to important differences in openne...

Effort is in progress for spatial and spatiotemporal hotspot detection, early warning, and security. A hotspot can mean an unusual phenomenon, anomaly, aberration, outbreak, elevated cluster, critical area, or object recognition and tracking. The declared need may be for monitoring, etiology, early warning, or management. The responsible factors may be natural, accidental, or intentional. This ...

SL2/PU!culture is of central importance to the fisheries sector in Bangladesh. It grew from next to nothing in the early 1970s to contribute about 11% of total exports in the mid-1990s (DOF 1995). No other primary commodity enjoyed such spectacular growth in post-independence Bangladesh. Although shrimp farming has had a significant impact on the economy of Bangladesh, it has had high environme...

This paper intends to estimate the potential impact of climate change on Taiwan’s agricultural sector. Yield response regression models are used to investigate the climate change’s impact on 60 crops. A price-endogenous mathematical programming model is then used to simulate the welfare impacts of yield changes under various climate change scenarios. Results suggest that both warming and climat...

This article examines the unequal distribution of credit and credit subsidies in the Brazilian agricultural sector from 1969 to 1990. Total credit subsidies exceeded US$ 40 billion in this period. The distribution across crops is studied econometrically. After controlling for area, the crops that benefited most had superior access to credit institutions, were tradeable, had high prices, and wer...

In this letter, we investigate the effects of crop yield and livestock feed efficiency scenarios on greenhouse gas (GHG) emissions from agriculture and land use change in developing countries. We analyze mitigation associated with different productivity pathways using the global partial equilibrium model GLOBIOM. Our results confirm that yield increase could mitigate some agriculture-related em...

Soybean is one of the main sources of foreign exchange credits for Brazil in the agricultural sector. There is increasing interest in growing this leguminous crop, especially in the southern region of Minas Gerais, due to its importance as an alternative for crop rotation with maize. In this respect, the study of the adaptability of new cultivars to the region is indispensable so as to obtain h...

India is one of the largest cotton-growing countries. Cotton is a fiber crop with varied applications from making tiny threads to fashionable clothing in the textile sector. In the near future, cotton crop will gain popularity as a multipurpose crop in India. The commercialization of Bt cotton in 2002 and consequently the fast adoption of Bt cotton hybrids by cotton farmers have enhanced the co...
