Controlled Environment Agriculture

January 3, 2018
Controlled Environment Agriculture

Controlled Environment Agriculture (CEA) is an advanced and intensive form of hydroponically-based agriculture. Plants are grown within a controlled environment so that horticultural practices can be optimized.

CEA techniques are not simpler than older systems for growing plants. Indeed, they demand sound knowledge of chemistry, horticulture, engineering, plant physiology, plant pathology, computers and entomology. A wide range of skills as well as a natural inclination to attend to details are necessary for a person to operate a successful CEA production in either a research or commercial setting.

The Cornell CEA program has worked with many different types of CEA facilities through the years. They developed a greenhouse hydroponic production method geared toward local food production. A prototype facility was built in Ithaca in the late 1990's and continues to function today producing more than 1000 heads of lettuce every day of the year. The CEA team continues to do research in the areas of supplemental lighting and commercial hydroponic vegetable production.

Urban Climate Adaptation and Mitigation Program (Urban CAMP): Session 5

March 26, 2025
3:30 PM - 6:00 PM
Queens, NY

The 2025 Urban Climate Adaptation and Mitigation Program (Urban CAMP) is designed to empower NYC farmers and agricultural advisors in their journey to gain and share knowledge and tools needed to be resilient in the face of climate uncertainty. This program is a partnership between Cornell University, the Harvest NY Program in Cornell Cooperative Extension, and the USDA Northeast Climate Hub. The Urban CAMP curriculum draws heavily from the Climate Adaptation and Mitigation Fellowship (CAMF), created in response to farmers' need for information and technical assistance related to climate change.

The 2025 Urban Climate Adaptation and Mitigation Program (Urban CAMP) will consist of a series of in-person workshops, trainings, online webinars, and in-person field days, tailored for the specific needs of farmers in and around New York City. The program begins February 26, 2026 and will run through September 2026. Five in-person training sessions will be held once a week on Wednesdays in February and March (Feb. 26th, March 5th, March 12th, March 19th, and March 26th). There will be a total of three in-person farm tours during the growing season (dates TBD). Urban CAMP participants will then work to develop an adaptation or mitigation plan for their urban farm, or a farm they work with.

Announcements

New York Urban Farms Sustainable Pest Management Fact Sheet Series

Cornell Cooperative Extension has partnered with dozens of urban farms across New York State to demonstrate and evaluate sustainable pest management strategies. Together with farmers, we found success using control methods that prevent or reduce crop losses through exclusion strategies, crop timing, host resistance, the introduction of beneficial organisms, and more. Regardless of management strategy used, common requirements for success include a knowledge of the pest and disease complex, preventative deployment and commitment to the process. The New York Urban Farms Sustainable Pest Management Fact Sheet Series includes case studies highlighting pest management techniques that New York urban farms have found valuable.

NYS Urban Growers Pest Management Needs Assessment

As part of a multi-year project exploring non-spray pest management options that are economically and environmentally sustainable for urban farms, we conducted a needs assessment with urban growers across New York State. The New York State Urban Growers Pest Management Needs Assessment presents findings on current pest management practices, challenges, and topics of future interest.
