Can Cities Feed Their Inhabitants? David Thorpe looks at the options A greenhouse developed by Priva, an international company that provides innovative solutions for the more efficient control of energy and water within indoor environments. There are three dominant trends to which cities and national governments must respond in order to secure food supplies for their people. First, between 1980 and 2011 the global population not dependent on agriculture doubled to 4.4 billion, and, according to the Food and Agriculture Organization this population is growing at a rate about five times that of the agriculturally dependent population. Second, the amount of agricultural land available for growing food is declining and will soon start to be adversely affected by climate change. Third, in 2011 agricultural subsidies in the world’s top 21 food-producing countries totalled an estimated US$486bn. The growing of food in cities won’t mean that conventional agriculture will disappear. His personal website is: www.davidthorpe.info

Blog » The Top 10 Plants for Removing Indoor Toxins Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside homes, indoor public spaces and office buildings. The indoor pollutants that affect health are formaldehyde, Volatile Organic Compounds (benzene and trichloroethylene or TCE), airborne biological pollutants, carbon monoxide and nitrogen oxides, pesticides and disinfectants (phenols), and radon. Through studies conducted by NASA, scientists have identified 50 houseplants that remove many of the pollutants and gases mentioned above. More information on this study as well as references and details on specific chemicals can be found on Dr. Dr. , conducted plant studies for NASA that determined that plants can clean pollutants in homes, offices, factories and retail outlets. Top ten plants for removing formaldehyde, benzene, and carbon monoxide from the air:

WeFeedUs announces PA-based commercial aquaponics facility Home / Scale Up / WeFeedUs announces PA-based commercial aquaponics facility Scale Up January 22, 2013AlgaeIndustryMagazine.com arlisle, Pennsylvania-based WeFeedUs, a sustainable resource management company developing a commercial scale sustainable operation integrating the production of produce, fish, algae and renewable energy, has announced it has constructed a commercial aquaponics facility. According to the company, the production of food will be driven by on-site managed aquaponics systems, Recirculation Aquaculture System (RAS), algae biomass production and green energy systems powering the facilities. The proprietary eco-process maximizes the utilization of nutrients, waste and other important natural components to promote the robust growth of sustainable produce, aquaculture, algae, and other co-products. The company is finalizing off-take agreements with several US Colleges that have world-class sustainability programs. More Like This… From The A.I.M.

This Japanese Vertical Farming Company Wants to... Nuvege (also called “Green Green Earth”) is a hydroponic vertical farming company based out of Kyoto, Japan. Currently they only produce lettuces but they appear to be a well-established business. This is what they say about themselves and their technology: Nuvege’s innovative hydroponic technology is unlike any other conventional hydroponic system that exists today. Nuvege’s proprietary lighting network (NLN) uniquely increases the yield rate of vegetable growth by equalizing light emissions that also advance photosynthesis through increased levels of carbon dioxide. Our unique Vertical Farming Environments utilize “vertical space” for our growth environments. Check out this video from their site (very basic but has some cool shots of their lab)

EarthBox Vertical farming: Does it really stack up? WHEN you run out of land in a crowded city, the solution is obvious: build upwards. This simple trick makes it possible to pack huge numbers of homes and offices into a limited space such as Hong Kong, Manhattan or the City of London. Mankind now faces a similar problem on a global scale. The world's population is expected to increase to 9.1 billion by 2050, according to the UN. Such is the thinking behind vertical farming. Better still, says Dr Despommier, the use of pesticides, herbicides and fungicides can be kept to a bare minimum by growing plants indoors in a controlled environment. A wide variety of designs for vertical farms have been created by architectural firms. “Without artificial lighting the result will be an uneven crop, as plants closest to the windows are exposed to more sunlight and grow more quickly.” The necessary technology already exists. He and his colleagues have created the South Pole Food Growth Chamber, which has been in operation since 2004.

Plantable: All-In-One Table & Trellis Hybrid Lets You Grow, Harvest and Eat Zahra Shahabi and Ollie Hammick/CC BY-NC-SA 2.0 Beyond the conventional planter on your balcony, there are many ways to grow food and herbs right in your own home, without the need to rely on a trip to the store. London-based designers Jamie Elliott and Liam Healy of JAILmake created this table that's a mix of eating surface and mini-garden, where the legs are re-fashioned as planters and trellises to support climbing plants. Jaime and Liam describe the motivation behind this simple but intriguing design they call "Plantable", which is handmade to order in their South East London workshop using English oak and metal: The Plantable reintroduces nature back into the experience of gathering, cooking and eating a meal. So far, they've tried and tested climbers, tomatoes, herbs and sweet peas. You can see more of JAILmake's hand-crafted work on their website.

My gorgeous wife Susanne got our farm’s aquaponics systems USDA Organically Certified in 2008. Also, our back Commercial Newsletter #10 has complete information (as of 5-10-2012) of all the organically certified aquaponics farms and their certifying agency that Susanne could locate. What does organic certification (hereafter referred to just as “certification” to save your time) mean for you and your farm? Why Is Certification Valuable To You? Because you can get double the prices for certified produce as you can for conventional.
