Conteúdo: | A hydrologic-based forage production simulation model (PHYGROW) and a populanon mixture simulation model (POPMIX) were uscd respectively lo simulate forage producrion and carrying capacity of a subtropical shrubiand complcx of over 34 species grazed by various ratios of cattle and goats with a popuiation of indigenous animais (white-tailed deer) over a 20 year simulated weather wofile. The Farm Levei Income and Policy Simulation Model (FLIPSIM) were used to evaluate and quannf' the impacts of alternativa rnanagement strategies and clirnate change on grazingland ecosystems. The study was cariied out to analyze thc feasibility and profitability of a representative cante goal farm in lhe South Texas. On average, nel cash farm ineome under 50:50 cattle:goat ratio and climatic condínons falis by as much as 2% relativa to 70:30 for lhe farra studied. Real net worth for lhe farm declines as much as 9.4% and 16% over the study period under the highest to lowest cattle:goat ratio and, dry to normal climatic conditions, respectively. The modeled results produced useful information showing the socioeconomic consequences for a typical South Texas farm impacted for alternativa management strategies and climatic conditions.
