California is the leading agricultural state in the country and it’s agriculture generates more than $45 billion annually. About 10 million acres of the state is intensively cultivated land, using roughly 80 percent of the developed water supply. Only a small fraction of these lands are managed deliberately in ways that minimize impacts to nature and maximize the services that nature can provide back to the farm. This has come at a substantial price to nature and the future resilience of agriculture. 

Maintaining a mix of natural areas along farm fields and along waterways can provide vital habitat and movement corridors for wildlife, as well as important services like pollination and pest control from native insects, erosion control, and improved water quality. Sustainable management of soils and crops themselves can further reduce the ecological footprint of the land use, and indeed provide habitat for some native species. 

Conservancy scientists are investigating these co-benefits, to inform how policy and market incentives could promote food production practices that sustain nature as well as people.
