Want to help mitigate global climate change? Grow some veggies.

Turning lawn into a vegetable garden can reduce greenhouse gas emissions, according to a new study by UC Santa Barbara research professor David Cleveland.

Using a lifecycle assessment model, Cleveland and his students demonstrated that greenhouse gas emissions can be cut by 2 kilograms for every kilo of homegrown vegetable when compared to the store-bought counterpart. The group’s findings appear in the journal Landscape and Urban Planning.

For their baseline scenario, the researchers modeled a vegetable garden based on converting an area of lawn to garden, replacing some conventionally produced purchased vegetables with ones from the garden and diverting some household organic waste and gray water from processing facilities for use as compost and water for the garden.
