The high agricultural process of the Argentine humid pampas forces the intensification and relocation of cattle and dairy systems into subhumid and semiarid region to keep their competitiveness. In consequence, there is an increasing water demand scenario in these fragile areas in relation with...

Selection of cattle with greater feed efficiency is known to be profitable. Savings in southern Australian beef production systems of $6.55 per breeding cow per year have been estimated for selection for lower residual feed intake (RFI), and an additional saving of $4.34 per breeding cow per...

The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with...

A spreadsheet-based tool that tracks cow-calf producer net returns (NR) and greenhouse gas (GHG) emissions was used to determine the impact of calving season for three typical farm sizes and four fertilization strategies in Arkansas. Economic and environmental changes were examined for spring,...

Concern over GHG emissions has producers analyzing cattle production alternatives. One way producers can modify emissions is by changing herd sire genetics. The ‘Bull Estimator’, part of a recently developed cow-calf profitability and GHG spreadsheet tool, shows that genetic change can...
