The decade-old Israeli blockade on Gaza has dramatically undermined the coastal strip’s agriculture sector.
The electricity crisis has exacerbated this problem. With electricity available for only three to four hours a day, most productive sectors in Gaza are debilitated to the point of paralysis.
But Palestinians in Gaza have long had to rely on their own resourcefulness to survive. They’ve powered cars with cooking oil and built homes from mud bricks. They created a tunnel industry that, according to the United Nations, became a lifeline for Palestinians in Gaza before Egypt mostly shut it down in 2015.
This resourcefulness has also been brought to bear on the agriculture sector. With overcrowding causing urban spread from one side, and an Israeli military no-go area infringing on mostly agricultural land on the other, arable land is at a premium.
Palestinians in Gaza have again had to think outside the box. They’ve moved upward to the rooftops.
That project involved more than 200 households provided with fish tanks and equipment for aquaponic units. Aquaponics is the practice of soilless vegetable growing in combination with fish tanks whose nutrient-rich wastewater is used as fertiliser.
The practice has since spread, as Palestinians in Gaza adapted the methods to suit their own needs and the materials available to them. The result provides a means to address a problem that has grown to dangerous proportions.
According to the UN, about 47% of Palestinians in Gaza suffer food insecurity as agricultural production has dropped off dramatically as a result of the Israeli-imposed blockade.
Given a high annual population growth of more than 3%, a moribund economy unable to recover under the blockade, Gaza desperately needs new ideas to feed a growing and impoverished population.
Dr Ahmad Saleh, an agricultural consultant and former professor in the Faculty for Agricultural Engineering at Al-Azhar University, is working to facilitate organic rooftop farming. To this end, he has established his own rooftop farm in the Tawam neighbourhood of Gaza City.
For Saleh, rooftop farming has another potential advantage other than making the most of scarce space. He used parts from old cars, plastic boxes and bottles to create colourful containers for the 60-square-metre space on his roof.
The area has been divided into two sections: one is for ornamental plants, including cacti and flowers, creating a pleasant space for socialising and a hub for family, friends and neighbors.
The other section is for produce. Saleh grows parsley, celery, sage, thyme, tomatoes, chilies, onions, eggplants, radishes, sweet peppers, seasonal lemons and beans.
“There are many useful benefits with this project,” he said. “First, the produce is free from harmful chemicals, avoiding any harmful effects of chemical fertilisers. Second, the food tastes far better than what is found in the markets.”
But the advantages are not confined to health and social benefits. Saleh said: “Rooftop agriculture enables and empowers people. It allows them to find effective ways to confront environmental problems and helps create a healthier population.”
This type of farming is also accessible to most people. Though aquaculture and fish farming can be involved and could raise costs, containers can be made from found recycled materials.
The most expensive component, said Saleh — assuming others, like him, build their own containers from the plastic and debris that is strewn around Gaza — is the soil itself, which is mixed with organic fertiliser.
“Many customers are beginning to become aware of produce grown without chemicals,” he said. “But they do need more labour and attention.”
Al-Sharqawi plans to build more containers. He said demand is increasing and he wants to keep on top of it.
Muhyeddin al-Kahlout, 65, started a rooftop farm in part for its social aspect.
A retired school director, al-Kahlout returned to Gaza in 1992 from Kuwait where he had lived and taught for more than 25 years. There, he picked up a passion for gardening, so when he retired and knew he was coming home, he decided to try the same in Gaza.
Al-Kahlout turned to the internet and learned some tips on rooftop gardening. He built wooden containers and created others from discarded plastic bottles, topping off the project by putting out an old bench for the family to enjoy.
Over the course of the past year he was able to grow lettuce, green beans and basil one season and tomatoes, pumpkins, peppers and eggplants in another.
He has also planted ornamental trees to create a space for family and friends. The project, in his view, is “entertainment”.
“We are experiencing severe power shortages and there is already a scarcity of recreational places. Many of my friends liked the idea. Now they are starting to think about doing the same on their rooftops.”
