Rooftop Farm Grows Veggies Sans Soil : Environment News

Buying organic and locally grown produce is a raging trend that is here to stay. And a new project in Israel called “Green in the City” is taking the trend to a whole new level, literally.

‘Green in the City’ grows mostly organic vegetables in floating beds of water (without soil) on the rooftop of Dizengoff Center, Tel Aviv’s central mall complex. Started by Mendi Falk, the project aims to bring the farm to the city, and fresh produce onto urban dwellers’ plates.

Lettuce, basil, bok choy, onions, tomatoes, and cucumbers are among the vegetables grown on Falk’s compact, 100-square-meter rooftop farm. And while just about anything can be grown on the farm, Falk concentrates mainly on leafy vegetables because they have the shortest life cycles.

Urban agriculture requires less water, no soil

The science behind this intriguing project is hydroponics, a type of gardening that grows plants using very little nutrient-rich water solutions and without any soil. There are different types of hydroponic systems, but they all essentially work by pumping just the right amount of nutrients and water directly to the plants’ roots. Unlike traditional agriculture, hydroponic gardening gives the grower control over the plants’ watering and feeding cycles, as well as over the strength and acidity of the nutrient solution that is given to the plants.

Falk’s farm also utilizes an aquaponics system: fish are grown in a tank that is connected to the plant growing beds, with water circulating between each other. The plants take in nutrients from the fish tank’s waste and clean the water that is pumped back into it.

The advantages are numerous: First and foremost, the plants grow faster and produce greater yields. These systems also take up less space, rule out the need for pesticides (since plant diseases and parasites are mostly soil-borne), and require less weeding. In addition, the rooftop garden needs less water as hydroponics uses 70 to 90 percent less water than conventional gardening.

“Harvested just 15 minutes before being served on the customer’s plate”

According to Falk, customers can taste the difference. “The taste is different not because the produce is growing in hydroponic systems, but because people are not used to eating fresh vegetables,” he tells NoCamels. “They’re used to eating vegetables that have been sitting in their refrigerator for days. Our vegetables are organic, pesticide-free, and truly fresh, because oftentimes they are harvested just 15 minutes before being served on the customer’s plate.”

Green in the City is a joint venture between Dizengoff Center and Falk’s company Living Green – which sells hydroponic and aquaponics systems to private consumers. “We believe that urban agriculture should be more spread throughout the city,” Falk says. “Since the farm is located on top of a popular space, people can easily come and see that the hydroponic method is not that complicated and they will be inspired to grow their own vegetables in their homes with hydroponic systems.”

A solution for world hunger? 

The farm’s produce is currently sold to two restaurants in Dizengoff Center – Café Greg and Garden Restaurant – as well as to Dizengoff Center’s farmers market for about $1 per unit, as opposed to organic vegetables sold at local supermarkets, which on average cost $2.5 per kilo. Falk says that 100 square meters are not enough to run a financially sustainable farm, and plans to expand to a 500-square-meter space on the Center’s roof in the coming months.

His vision for hydroponic systems extends way beyond his own business interests. “I think this is a part of a bigger solution for world hunger,” Falk explains. “Of course, hydroponics will not replace traditional agriculture as the major source of food, but in countries where there is not enough fertile ground or enough water, hydroponics can provide a much needed solution.”

Desde que el ingeniero de agua israelí Simcha Blass, revolucionó el concepto de riego por goteo, se ha convertido en una gran industria israelí que ha estado ayudando a las naciones del mundo se alimentan a su gente. En Kenya, Senegal, Sudáfrica, Benin y Níger, a las personas que padecen hambre se les están ayudando a producir más alimentos, muchas veces en, tierras estériles y secas. La nación que ha de ser «una luz para las naciones» está ayudando a las naciones hambrientas a comer. Gracias a Dios por Israel!


Since an Israeli water engineer, Simcha Blass, revolutionized the concept of drip irrigation it has become a large Israeli industry that has been helping nations of the world feed their people. In Kenya, Senegal, South Africa, Benin and Niger, hungry people are being helped to produce more food, many times on dry, infertile land. The nation who is to be “a light to the nations” is helping the hungry nations eat. Thank God for Israel!


 

Cannabis Heals Fractures : Health News of Israel

Cannabis, or marijuana, was used as a go-to medical remedy by societies around the world for centuries. But the therapeutic use of marijuana was banned in most countries in the 1930s and ’40s due to a growing awareness of the dangers of addiction. The significant medical benefits of marijuana in alleviating symptoms of such diseases as Parkinson’s, cancer, and multiple sclerosis have only recently been reinvestigated.

A new study by Tel Aviv and Hebrew University researchers explores another promising new medical application for marijuana. According to the research, the administration of the non-psychotropic component cannabinoid cannabidiol (CBD) significantly helps heal bone fractures, possibly even preventing them in the future.

The study, conducted on rats with mid-femoral fractures, a serious fracture in the thigh bone, found that CBD — even when isolated from tetrahydrocannabinol (THC), the major psychoactive component of cannabis — markedly enhanced the healing process of the bone fractures after just eight weeks.

Undeniable clinical potential

In earlier research, the same research team discovered that cannabinoid receptors within our bodies stimulated bone formation and inhibited bone loss. This paves the way for the future use of cannabinoid drugs to combat osteoporosis and other bone-related diseases.

“The clinical potential of cannabinoid-related compounds is simply undeniable at this point,” said Dr. Yankel Gabet of TAU’s Bone Research Laboratory. “While there is still a lot of work to be done to develop appropriate therapies, it is clear that it is possible to detach a clinical therapy objective from the psychoactivity of cannabis. CBD, the principal agent in our study, is primarily anti-inflammatory and has no psychoactivity,” meaning they do not results in alterations in perception, mood, or consciousness.

According to Dr. Gabet, our bodies are equipped with a cannabinoid system, which regulates both vital and non-vital systems. “We only respond to cannabis because we are built with intrinsic compounds and receptors that can also be activated by compounds in the cannabis plant,” he said. The researchers found that the skeleton itself is regulated by cannabinoids. Even the addition of a non-psychogenic compound acting outside of the brain can affect the skeleton.

Separating the components out

“We found that CBD alone makes bones stronger during healing, enhancing the maturation of the collagenous matrix, which provides the basis for new mineralization of bone tissue,” said Dr. Gabet. “After being treated with CBD, the healed bone will be harder to break in the future.”

The researchers injected one group of rats with CBD alone and another with a combination of CBD and THC. After evaluating the administration of THC and CBD together in the rats, they found CBD alone provided the necessary therapeutic stimulus.

“We found CBD alone to be sufficiently effective in enhancing fracture healing,” said Dr. Gabet. “Other studies have also shown CBD to be a safe agent, which leads us to believe we should continue this line of study in clinical trials to assess its usefulness in improving human fracture healing.”

Rosh Pina: Israel’s first village

Now a thriving and picturesque artists’ colony, Rosh Pina was the site of two not-so-successful farming ventures in pre-state times.

Ask most people what was the first Jewish settlement in modern Israel, and most will say Petah Tikva.

However, three months before Petah Tikva was founded in 1878, eighteen religious Jews from Safed (Tzfat) decided to embark on a Zionist farming enterprise and walked 90 minutes to the slopes of Mt. Canaan to build a new settlement, taking advantage of the area’s three natural springs. They called it Gai Oni.

“They didn’t want to beg for money from European Jews,” says tour guide and local resident Akiva Oren. “They wanted to work the land as farmers and make their own living.”

Though the venture folded after three years, it formed the basis for what is now the village of Rosh Pina (“cornerstone”) in the Upper Galilee. This village offers spectacular views of the Sea of Galilee, the Hula Valley, Mt. Hermon and the Golan Heights. Many of its historic stone buildings and gardens have been reconstructed and preserved, while new structures, parks and art galleries have been added in recent years.

Today the town offers about 400 guest rooms and more than 30 restaurants and pubs selling Middle Eastern, North American, South American, Italian and French fare.

Rosh Pina can be explored within a few hours, while its bed-and-breakfast facilities in restored stone houses serve as a quaint central base for tourists planning trips to the Galilee’s many Jewish, Christian, natural and historical sites nearby.

Though it’s a sleepy little town of about 2,500 residents, pop star Madonna reportedly looked into buying a house here because in the ancient Jewish mystical tradition, Rosh Pina is the site where the Messiah will appear.

Romanians arrive with wooden boats

In 1882, the First Aliyah movement saw many idealistic Europeans emigrating to their ancestral land at a time when the Jewish population in Palestine was about 50,000 in total.

That year, a Romanian Jew named Moshe David Shuv arrived on a boat at Jaffa Port, bought a horse and rode all the way up north looking for the right spot to settle along with at least 40 families from his village who’d given him funds to get started.

“When he reached Rosh Pina [Gai Oni], he said ‘I found it!’ and he sent a telegram describing it as similar to their own Romanian village – high up in the mountains, chilly, with a lot of water — and they all packed up and came by boat to Beirut, walked to Rosh Pina and established homes there,” says Oren.

By this time, most of the Safed adventurers had given up and left, and the few landowners there were Arab families.

“The Romanians slowly bought property from the Arabs, who were happy to teach them about farming and happy to sell them their land, because they needed money to pay off the Turks to keep their sons out of the army,” according to Oren. The renamed town of Rosh Pina was officially recognized by the state of Israel in 1953.

Shuv was the great-great-uncle of Oreet Segal, an Israeli tour guide. Segal says her grandmother Leah was five years old when she arrived from Romania with her parents, Mordechai and Rivka Katz. Rivka was Shuv’s sister.

“My grandmother remembered living in hillside caves at the beginning,” says Segal. “The first thing they built was a mikvah [ritual bath] and then small homes. They tried to be farmers, but didn’t know much about it.”

Wooden boats, mulberries and perfume

The European newcomers had naively brought along wooden boats, assuming they could earn some money by fishing in the springs. Quickly realizing these waterways were unsuited to commercial fishing, they instead put the boats together to form the roof of the wooden synagogue built in large part by Mordechai Katz. “You can still see the contour of the boats if you look up at the ceiling,” says Segal.

Farming turned out to be not much more successful than fishing. “It was really hard to survive,” says Oren. “Then, Baron [Edmund de] Rothschild sent them help. Rothschild helped them build their huge, elegant synagogue and gave a stipend to each family to help them buy a cow and a mule.”

As he did in other new settlements he supported, including Petah Tikva, Rothschild sent paid emissaries to oversee how his money would be spent. “These clerks didn’t know much about agriculture either,” says Segal. “They lived high on the hog compared to the settlers, and it caused a lot of resentment.”

First, the families tried planting mulberries to grow silkworms, and then they planted flowers to make perfume. Both ideas were flops, says Segal. “They suffered a lot from diseases and from hostile neighbors, too. My great-grandfather, who was very tall with red hair and a red beard, rode around guarding the settlement on a big white horse.”

Leah married the widowed religious leader of the community when she was young, and Segal’s father was the eighth of their 10 children. “They stayed in Rosh Pina until the start of World War I, and then my immediate family moved to Jerusalem,” she says.

In 1929, Prof. Gideon Mer established a malaria research laboratory in Rosh Pina, which gained worldwide recognition as his work helped stop the malaria epidemic among new agricultural settlers in the region — and also overseas, once Mer was made a medical officer in the army of King George VI. The preserved house contains an exhibit of ancient items from various periods, such as old plows, laboratory equipment and textbooks.

An artists’ colony

For many years, this “Mother of the Galilee settlements” remained a sort of forgotten backyard, as Segal puts it.

“Rosh Pina was never really successful until the 1980s or 1990s, when it became a haven for artists looking for inexpensive old homes. It started getting a rebirth as people bought up houses to make zimmerim [bed-and-breakfasts] and ceramic and art galleries. There are a lot of places to stay here today, and the weather is beautiful with a high elevation, so it’s pleasant in the summer with a great view.”

When she guides tourists in Rosh Pina, Segal shows them the house where her father was born, as well as the synagogue and the mikvah. “A lot of the original houses are there, just ‘yuppified’ and glorified,” she says, “including the home of the well-loved schoolteacher. When he passed away, they made a fancy memorial to him in the cemetery.”

Some of the retail shops from the late 19th and early 20th centuries are also in the process of being fixed up, along with one of the first hotels in the Galilee. The house where the Rothschild employees worked has been turned into offices and a museum featuring an audiovisual presentation about the history of Rosh Pina. The nearby Baron’s Gardens, modeled on the grand gardens at Versailles, are also open to the public.

A portal to the Galilee

Oren likes to use Rosh Pina as a starting point for tours of other spots in the Galilee, including Safed, Tiberias and the Hula Lake, a major attraction for migrating birds and the people who enjoy watching them.

“I take people for a few hours in Jeeps to see the north, which is really unique,” says Oren. “Rosh Pina is a good base for traveling in all four directions.”

He starts in the valley and climbs up all the way to the highest ridge, over 900 meters high, where snow falls every winter. He takes people west to the border with Lebanon, to the Hula to see the migrating birds, to theKorazim National Park, a Second Temple-era site overlooking the Sea of Galilee, and to Tel Hatzor, a national park on the ruins of the biblical King Solomon’s summer palace.

Biking is one of the most popular activities in the mountains around Rosh Pina, with trails from extreme to beginner. A new 25-kilometer section of the Israel Bike Trail was just opened this fall by the Keren Kayemeth LeIsrael-Jewish National Fund (), and there are also trails for horseback riding and hiking.

Where to stay

Accommodations in the Upper Galilee get more plentiful and posh all the time. Small boutique suite hotels in restored Rosh Pina stone buildings offer luxurious rooms with features such as hot tubs, wood floors, and private gardens from which to take in the views of Mt. Hermon, the Golan Heights and the Hula Valley.

Among the 30 bed-and-breakfast hotels in Rosh Pina is an environmentally conscious enterprise with a gray-water system (the water from the Jacuzzi and showers is used to irrigate the organic garden) and energy-efficient lighting. Some of these zimmerim are strictly kosher, while on the outskirts of Rosh Pina are high-end hotels.

In nearby Hatzor is a 26-room Mediterranean chateau-style boutique estate hotel in a two-story Jerusalem stone house surrounded by 6.5 acres of natural wine country. Guests munch on cheese, fruit and vegetables from local farms along with herbs and spices grown in the hotel gardens, and can lounge at the outdoor pool and Jacuzzi.

Seems like Madonna has plenty of places to stay even if she doesn’t buy any property in Rosh Pina.
