Welcome to Our Air Quality Research and Extension Program

Our goal is to develop an integrated research and extension program to assist Kansas in addressing critical environmental issues that impact the sustainability of local communities.

Kansas is experiencing air quality problems such as smoke from prescribed pasture burning and air emissions from livestock production. Also, as producers face new weather patterns and regulations put in place to limit green house gases emissions, there is a need for producers to mitigate and to adapt to the effects of climate change.

With support from our applied research on these issues, we aim to effectively inform and influence producers and consumers to move agricultural production toward practices that are environmentally sound and economically viable, balancing the needs of public health and the environment with the needs of industry.
