rooftop beekeeping

European honeybee

According to urban apiarist Trey Flemming, bees that live in cities are generally healthier than their rural counterparts.  Bees are broad spectrum pollinators, which means that they leave the hive and look for varied types of nectar sources.  In the countryside, many bees end up visiting agricultural crops such as corn and soybeans, which are commonly doused with chemical herbicides and pesticides.  By contrast, urban bees feed on local flora found within street plantings, parks, roof gardens, and vegetable gardens.  These small-scale polycultures are generally not treated with herbicides or pesticides, and so the visiting pollinators do not bring chemicals back to the hive.

Trey co-founded Urban Apiaries in 2009 in order to sell local honey throughout the greater Philadelphia area.  The business now cares for 32 hives, located in seven apiaries throughout the city.  Several of these apiaries are situated on rooftops, such as those at North Philadelphia’s SHARE Food Program and Chestnut Hill’s Weavers Way Co-op.

Inspecting the frames

Tens of thousands of European honeybees (Apis mellifera) surrounded us on the roof of SHARE Food Program as they went about their business, and we ours.  Trey tended the hives by first spraying pine needle smoke to calm his busy workers, and then he removed each hive’s lid to inspect its contents.  During the inspection we observed bees working the hives and honey cells of various colors.  Trey removed the most mature supers from each hive in order to extract the honey offsite in his honey house.  Urban Apiaries sells its honey in shops, markets, and farm stands throughout the city, and each jar contains the apiary’s zip code on the label.  Visit the company’s website at

dreaming big

As discussed in the previous post, the importance of selecting the right person to write the book’s foreword is paramount.  The most appropriate candidates for “Eat Up” fall within the categories of food writer, community activist, designer, and practitioner.  Ideally, a prominent person in one of these fields will accept the invitation to write the foreword, thereby promoting their own goals while contributing to the growing rooftop agriculture movement.  Writing the foreword could help the following authors to promote their own initiatives by addressing:

– Food author:  food systems, food access, food equity, organics, nutrition

– Community activist:  community building, education, food justice, public health

– Designer:  roof access, building codes, integrated design

– Practitioner:  feasibility, cost, sales outlets

My dream team top pick shall remain unnamed, but I searched high and low for a personal connection to this literary superstar.  The one connection that I found did not yield the results that I hoped for, an so the jury is out on whether to approach the author via email, mail a manuscript and written letter, or schedule an appointment and fly across the country to talk.

diversified marketing

Writing a book is the easy part.  The challenge seems to come with publication and promotion.

The first draft of “Eat Up” was targeted toward academia, and the tone was dry and, well, academic.  The current version of the book is geared toward a much broader audience, which includes policy makers, practitioners, city planners, designers, community activists, economists, and academics.  The book is very readable and its new content targets these varied audiences, but how do you attract these readers in the first place?  The answer lies in promotion, strategically selecting a publisher, and finding a key person to write the foreward.

Since the book bridges several disciplines, the promotional strategies, publishing house, and foreward author would ideally target different audiences.  If the publishing house is well respected in the design community, for example, then a food author should be approached to write the foreward.  In theory, this method of diversified marketing will lure in a wide variety of readers, and help spread the word and push sales.

160,000sf north philadelphia rooftop farm

Philadelphia is blessed with a burgeoning urban agricultural scene, which provides residents with access to fresh, locally produced, often organic food.  While most of these farms and gardens are concentrated around the city’s central and western regions,  North Philadelphia contains a remarkable dearth of fresh food outlets.

SHARE Food Program is a nationwide food distribution entity that founded a local distribution center and urban farm in the Hunting Park neighborhood of North Philadelphia.  The facility occupies a 180,000sf manufacturing building, and utilizes the surrounding site for at-grade food production and parking.  In an effort to increase both production levels and the availability of fresh food for the surrounding community, SHARE is working with the Philadelphia based Community Design Collaborative  to develop a design for a rooftop farm.

The 160,000sf rooftop will accommodate several types of production, and will also contain green roof areas (for stormwater management) and a photovoltaic array (to generate energy for the building).  At this point in the design process the rooftop farm will likely facilitate row farm, raised bed, and greenhouse production, as well as bee hives, which already occupy the roof.  Additional programmatic elements may include demonstration areas, composting bins, rainwater harvesting, and even an outdoor classroom.

Stay tuned for design updates, photographs of rooftop honey collection, and SHARE’s journey towards securing project funding.

book teaser

Productive rooftop farms and gardens around the globe continue to prove that rooftop agriculture is possible.  The question, though, is not of feasibility; it is of viability.  Is rooftop agriculture viable in the United States given the current environmental, economic, and cultural climates?  How can we shape our policies, architecture, and culture to foster the long-term success of rooftop agriculture, particularly at the neighborhood and city scales?

“Eat Up” will reveal how urban rooftop agriculture is feasible at varying scales, depending on what conditions are present.  Reshaping our political, architectural, and cultural conditions in an informed way can make rooftop agriculture a reality for more individuals and communities.  The book is intended not only to educate the reader as to what is possible, but also to provide a springboard for innovation.  As hopefully the first book ever published to exclusively focus on rooftop agriculture, the goal of the book is to explore the subject matter’s potential, to understand our limitations, and to breed inspiration.

an introduction to the author

With a passion for productive infrastructure, Lauren Mandel works as a Project Manager and Rooftop Agriculture Specialist at the Philadelphia based green roof firm Roofmeadow (formerly Roofscapes).  At Roofmeadow, Lauren designs green roofs, oversees green roof construction, and is integral to every rooftop agriculture inquiry and project that the firm encounters.

Lauren began exploring the viability of urban rooftop agriculture while in graduate school at the University of Pennsylvania, where she earned a Master of Landscape Architecture. With six years of professional landscape architectural and green roof design experience, Lauren is in the process of refining her thoughts on rooftop agriculture in book form. If published, “Eat Up” will be the first book ever written to exclusively focus on rooftop agriculture.

In her spare time, Lauren lectures on green roofs and rooftop agriculture, and is currently assisting with the design of a potential 160,000sf rooftop farm in North Philadelphia. She also loves backpacking and extreme dog walking.
