Urban Ag News Issue 15  | The Lighting Issue |  October 2016

Urban Ag News Issue 15 cover story focuses on the lighting research being conducted at Wageningen University in the Netherlands. Leo Marcelis, head of chair group horticulture and product physiology, talks about how university researchers are studying the effects of LED lights on the growth, flowering and fruiting of vegetable and ornamental plants in controlled environments.

Wageningen University researchers are looking at different aspects of lighting, including light spectrum and energy savings. The issues of most interest to Dutch growers include year-round production, fruit quality and energy savings.

Shalin Khosla, greenhouse vegetable specialist at Ontario Ministry of Agriculture, Food and Rural Affairs, talks about developing the right light recipe for greenhouse vegetable crops. Canadian researchers at the Harrow Research and Development Centre are working with growers to determine which horticultural lights are the most effective and efficient for producing tall greenhouse vegetable crops.

Michigan State University hosted the 8th International Symposium on Light in Horticulture in May. This was the first time the symposium, which began in 1969, was held in the United States. Scientists, university researchers, graduate students and industry representatives from 25 countries attended the event. Michigan State horticulture professor Roberto Lopez, who was instrumental in the success of the symposium, provides insight into what occurred during the symposium.

A number of organizations and companies in and outside Panama are looking to develop El Centro de Investigación para la Producción de Agricultura en Ambiente Controlado (CIPAC), a world-class controlled environment agriculture research and development center. Representatives from some of the organizations involved with the development of CIPAC shared their insight with Urban Ag News on the work being done on this proposed CEA research center.

The people in Venezuela are in the depths of a full-blown food crisis. The Venezuelan government’s “Great Agro-Venezuela Mission” is promoting city farming, resulting in a record number of citizens growing their own food. As the country has been swamped with images of empty shelves, soul-crushing lines and food riots, government administrators are urging city dwellers to embrace urban agriculture. Officials speculate home-grown gardens could account for more than 20 percent of the food supply by 2019.
