Against a backdrop of skyscrapers and jungle-clad hills, earth-filled boxes are spread out on the roof of the 14-storey building, where a wide variety of produce including cucumbers and potatoes are cultivated.

It is one of several such sites that have sprung up in Hong Kong’s concrete jungle, as the appetite for organic produce grows and people seek ways to escape one of the most densely populated places on earth.

“I am happier eating what I grow rather than food I buy from supermarkets,” said Melanie Lam, a 28-year-old nurse, who comes to the “City Farm” in the Quarry Bay district of Hong Kong’s main island about twice a week.

“Compared to vegetables from the supermarket, vegetables that I plant are sweeter and fresher. It gives me a greater sense of satisfaction.”

With most of the southern Chinese territory’s seven million people living in tower blocks and land prices sky-high, unused roofs are some of the few places in the most heavily populated areas for budding vegetable gardeners.

The money-obsessed city has been late to latch on to rooftop farming, which has been popular in cities such as London and New York for years.

While there are no official figures for the number of sites, as no licence is needed to set one up, anecdotal evidence suggests their popularity is growing.

“I think urban farming is becoming more popular… we have grown bigger in a short time,” said Osbert Lam, the founder of “City Farm”, which has about 100 regular gardeners two years after opening.

There are 400 growing boxes on the 10,000-square-foot (930-square-metre) rooftop available to rent for between HK$150-200 ($20-25) a month each.

“People who come to the farm are so happy — It’s like a tranquilliser, it’s a way out,” added Lam.

In To Kwa Wan in the east of the Kowloon peninsula, one of the founders of another rooftop farm says the project has given a boost to the neglected neighbourhood, which has poor transport links and a predominantly elderly population.

Chu Pui-Kwan and two friends came up with the idea of setting up a vegetable garden on the unused rooftop of a 12-storey building.

Using old planks and other materials salvaged from construction sites, they assembled growing boxes, and then decided to get the local community involved before the farm opened in November.

“We invited the older people from around this area to come up, we gave them paints and had them paint the different boxes,” she said. “They had so much fun.”

Now the brightly decorated boxes are filled with a huge variety of vegetables and herbs, including spinach, peas, lemongrass, mint and rosemary, providing a splash of colour to the drab neighbourhood.

The site has regular open days and runs classes to teach people about urban farming.

Chu is also involved in Time To Grow, a company which aims to improve access to locally produced food.

It is running classes once a week on Victoria Peak, the highest point on Hong Kong’s main island, where participants have stunning views over the city.

“The whole idea is to get into each individual home a little bit of green… rooftops, windows, even one pot at a time,” said Chu.

Official figures suggest organic food is becoming increasingly popular in Hong Kong, with the number of farms taking part in a government-run scheme to encourage organic agriculture rising to 193 in June this year, from 123 in 2008.

But despite the hobby’s growing popularity, there is little sign of Hong Kong’s rooftop farmers producing enough crops to sell for profit, unlike their counterparts in cities where space is not so scarce and the idea took root earlier.

Just three percent of vegetables consumed in Hong Kong are grown locally, according to government figures.

California state agencies today released the 2012 Bioenergy Action Plan to accelerate clean energy development, job creation, and protection of public health and safety.

Bioenergy is energy produced from organic waste such as agricultural, forest and urban wastes that would otherwise go into landfills or be burned. Increasing production of bioenergy in California can create thousands of new jobs, especially in rural areas that have been hit hard by the economic downturn. Bioenergy also helps to protect public health and safety by reducing the risk of wildfires and the pollution from landfills, dairies, wastewater treatment facilities, and other organic wastes.

“Swift action on bioenergy will create jobs, increase local clean energy supplies, and help businesses grow in California,” said California Natural Resources Secretary John Laird. “Increasing bioenergy opportunities will also help California meet its climate change goals and protect public health and safety.”

The 2012 Bioenergy Action Plan was developed by state agencies and outside experts under the leadership of Governor Brown’s Office. The state agencies responsible for developing and implementing the plan are the Natural Resources Agency, Department of Food and Agriculture, California Environmental Protection Agency, Public Utilities Commission, Energy Commission, Department of Forestry and Fire Protection (CAL FIRE), CalRecycle, and the State Water Resources Control Board.

The plan contains more than 50 recommended actions to increase the sustainable use of organic waste, expand research and development of bioenergy facilities, reduce permitting and regulatory challenges, and address economic barriers to bioenergy development. The plan will help facilitate the creation of more than 4,000 jobs and help California meet its clean energy, waste reduction and climate change goals.

“Bioenergy is an exciting new frontier for agriculture,” said Karen Ross, Secretary of the California Department of Food and Agriculture. “It creates jobs, reduces energy costs and reduces pollution. Early adopters are already realizing these benefits and are blazing the path towards self-sufficiency for agriculture.”

Expanding bioenergy development benefits California agriculture by providing an onsite or local source of clean energy, either electricity or liquid fuels for farm and other vehicles. Technologies such as anaerobic digestion also reduce waste and pollutants from dairies, agricultural trimmings and residues, and food processing operations. Bioenergy generation can also produce biochar, a valuable soil amendment that can be used in place of chemical fertilizers.

“Wildfire is increasing dramatically in California, but there are ways we can reduce the risk to public health, safety and property,” said CAL FIRE Chief Ken Pimlott. “Generating energy from forest waste helps to reduce dangerous fuel loads in our forests while providing jobs and local energy supplies in forest communities.”

Wildfire is an increasing threat in many parts of California, costing hundreds of millions of dollars per year in fire suppression and property losses, not to mention impacts on public health and safety. One of the most important and cost-effective ways to reduce forest fire hazards is to generate energy from forest biomass collected to reduce dangerous fuel loads. Using forest biomass to generate energy protects health, safety and property while providing jobs, income and local energy supplies.

California currently produces about 600 megawatts of electricity and 50 to 100 million gasoline gallon equivalents from organic waste each year. Bioenergy facilities employ about 5,000 people and contribute $575 million to the California economy. By reducing the economic and regulatory barriers to bioenergy development in California, the Bioenergy Action Plan will help to nearly double these numbers.

“The state of California has the most comprehensive and thoughtful bioenergy policies in the world,” said Michele Wong, Chief Executive Officer of Sacramento’s Clean World Partners. “By coordinating waste, energy and air quality, we are in the midst of a technology revolution that will dramatically reduce garbage and pollution while creating a clean energy future.”

Clean World Partners – which builds facilities that transform food and green waste to renewable energy and soil – will break ground in September on its third major commercial facility this year.

“Our company has created 30 clean tech jobs this year and stands to create more than 400 jobs in the next three years,” continued Wong.
