Agriculture contributes majorly to greenhouse gas (GHG) emissions principally from methane and nitrous oxide with meat and dairy products accounting for approximately half of food-generated GHG emissions. A study on influence of selected intensive chicken management practices on GHG emissions in Southwest Nigeria showed patterns at which these practices contribute to environmental issues. Extension officers and livestock researchers were interviewed to provide information on the practices in the study area; this was corroborated with identification of same, by selected farmers. The ambient air quality within and around chicken farms in the area was monitored using a combination of in-situ instrumental measurements and sampling with Gilian pump/impinger containing absorbing solution (at 4.0 LPM for 20 minutes) and subsequent analysis in the labouratory showing gases emitted on different farms at varying distances of 25m and 100m from the farms. There were no reported difference in the air Suspended Particulate Matter but was evident in the CH4 and NH3 content of the air corroborating previous data (t= 3.22, p=0.03). Environmental-friendly-alternative practices were suggested by experts in livestock management and climate change issues, but farmers had constraints in the knowledge, attitude and practice of these alternatives in Southwest Nigeria. Environmental issues can be curtailed if environment-friendly-alternatives recommended by researchers are introduced through appropriate extension methods to substitute for traditional ways of managing chicken. There is need to consciously raise awareness of environment issues in the short-run among early career researchers and in the long run a deliberate campaign in schools to focus young minds into investigative enquiries on the environment and how best society should adapt as environmental changes that occur are most often irreversible.
