Energy Economics: CO2 Emissions in China and by a farm simulation model. We take a ‘bottom-up’ approach that builds incrementally on approaches and data standards that have proven useful for field-level analyses. A schedule of field operations links field-level production process to enterprise-level resource accounting. Prices convert res

Economics of Electricity Supplyinfestation correspond to very high risk magnitudes. Yield losses due to pest injuries are often strongly influenced by changes in production situation, and, therefore, by variation in attainable yield. The pattern of this relationship strongly depends on the nature of the pest, however. Different p
