Abstract

Concerns about global climate change has become increasingly apparent with increasing debates and discussions on the subject at an international level.Brazilian cattle effective is the largest commercial herd in the world, emitting about 50 kg of methane per animal each year. Considering this significant participation of Brazilian cattle ranching in the emission of Greenhouse Gases (GHG), the present study aimed to analyze the advances in Brazilian research on beef cattle production activity and its impact on the environment over the past 25, in central Brazil, which concentrates the most effective cattle. Documents published by Embrapa Beef Cattle during this period were used as database. As a way to measure the environmental impact of the activity, we used the average of methane emissions from enteric fermentation and manure management of the animals, multiplied by the effective region. Moreover, a Boolean Matrix was used as a tool to compare periods and variables. The results indicate that studies on the impact of livestock farming on the environment did not respond satisfactorily to the individual reduction of methane by cattle over the period, regardless of the considerable increase in beef production.
