A New Bio-Gas System in Palestinian Susya

in May 2010, the Bio-Gas project was launched to install systems for producing gas from sheep and goat dung for the domestic energy needs of the Palestinian hamlet of Susya (Susiya). This project was the initiative of Yair Teller, together with The Villages Group and Arava Institute. The first sytem was installed in the dwelling compound of the Hajj Ismail Nawaj’ah family, in Susya. Subsequently, two similar systems were installed in the dwelling compounds of another two families of the same clan in Susya. These are small systems of 4 cubic meters, each providing one family’s cooking needs.

In the two years since, Yair Teller continued developing his expertise in bio-gas. He joined three partners – Erez Lantzer, Oshik Efrati and Danny Dunayevsky, who together formed the Ecogas company. Ecogas and the Arava Institute are now pursuing the development of additional bio-gas systems in Palestinian Susya. Currently, together with the villagers, they are working to install a new 16-cubic-meter system in the area of the Hasan Shinran family in the western part of Susya.

The eastern part of Susya is inhabited mostly by families of the Nawaj’ah clan and is in Area C (in which permission for construction has been temporarily left in the hands of the Israeli Occupation authorities according to the Oslo Accords).

Last month, the Occupation regime’s “civil administration” issued demolition orders for most of the dwellings in that part of Susya. The residents, with the help of the Village Group and many other Paletinian, Israeli and international partners, are fighting these unjust orders in court and in the public sphere.

The western part, inhabited mostly by families of the Shinran clan is in Area B (where construction is authorized mostly by the Palestinian Authority). The new bio-gas system is constructed in this part of Susya, and is relatively safe. Unlike its predecessors, this system is meant to supply not only gas for family needs, but also for winter heating of the local schoolhouse – is also under threat of demolition by the “civil administration”, who claims it lies about 150 meters inside Area C.

According to plan, as soon as the bio-gas system itself will be completed, the second phase will begin, whereby two green-houses will be created at this site: one for educational purposes, in the area of the school. The schoolchildren of Susya will cultivate this greehouse under guidance from Arava Institute instructors. Thus they will learn to apply ecological principles in farming. The second green-house will be built in the Hasan Shinran compound, and to grow vegetables for both local consumption and marketing. Crops of both planned green-houses will be fertilized by compost produced from the surplus production processes of the gas system.

In conclusion, to the best of our understanding, when the heart listens, other hearts are heard, and fertile cooperation ensues. Even if the demolishing hand carries out its threats, the hearts will go on beating. Hearts are not to be demolished.

Settler Front-Group Presses Government to Accelerate Demolition Frenzy, Tripping Itself Up in the Process

We previously reported here on the worrisome escalation in demolition of Palestinian structures in South Hebron Hills. The body issuing the demolition orders is the deceptively-named “Civil Administration”. Contrary to its name (invented in the 1980’s by Ariel Sharon to mislead the outside world), this “Administration” is in fact a military body (its former name was simply “military government”), and its head is a general serving full-time in the Israeli military. It claims authority to run Palestinian civilian life in the less-densely populated West Bank “Area C”, which accounts for some 60% of the territory and about 150,000 Palestinian residents.

We will continue to shine a light upon the ways in which this “Administration” misgoverns Palestinian life. A future post will discuss the demolition orders on solar-wind energy systems installed at rural Palestinian communities by our friends, the Israeli NGO COMET-ME; systems funded with the help of donors and governments across the world.

Meanwhile, enter another player, stage right. In late February, an Israeli NGO called “Regavim” submitted a High Court appeal, together with the Sussya settlement, against the military – claiming that it should demolish more Palestinian homes in the region, and faster! We kid you not. Here is the original appeal (Hebrew, pdf).

The mysterious-sounding Regavim NGO presents itself in the appeal as “an a-political movement… to prevent illegal takeover of national lands by certain bodies”. However, its own publicized record reveals that its main business is 1. To force the government’s hand to destroy Palestinian structures, whether in the West Bank or in Israel itself, 2. To identify and suggest to the government new opportunities for such demolitions, and 3. To try and stop demolitions and evictions of unauthorized Israeli-settler structures in the West Bank. “A-political”, indeed. To cap the irony, Regavim’s head Rabbi Yehuda Eliyahu himself lives in an unauthorized settlement-outpost in northern West Bank. Their main field worker, Ovadia Arad named as a co-plaintiff, is a settler as well.

Regavim is emblematic of a trend in Israeli far-right circles. Since they recognize the power and appeal of basic human rights and justice, they have been setting up phony and mendacious imitations of respected human-rights organizations working on Palestinian human rights issues. These imitations turn the human-rights terminology on its head, in order to leverage the moral authority associated with it, while confusing and misleading the general public.

In the appeal, Regavim and the Sussya settlers refer to themselves as “residents of the area” and “farmers”. That is, they – who settled in the 1980’s as part of a heavily-subsidized takeover of Palestinian lands – pretend to be the indigenous, original residents. The A-Nawwajeh family of Palestinian Susiya (named as defendants 4 through 34), having lived in the area for generations, suddenly become – in Regavim’s upside-down terminology – the squatters who had set up “illegal outposts” arround the “poor settlers”; trouble-makers who should be evicted to the town of Yatta.

Of course, this is a bald-faced lie, one of dozens of distortions and outright lies in this frivolous Regavim appeal. Even the Israeli authorities have already conceded that the A-Nawwajeh, like other Palestinian South Hebron Hills residents, are the legal owners of their land. Unlike the settlers of Sussya, they have to live on the land with no government assistance, and against the continued restrictions from the military and physical harassment from the settlers. Here are a couple of pictures from our recent visit to the A-Nawwajeh hamlet.

Apparently, truth or justice are not a goal of Regavim, or of the Sussya settlers who have unfortunately joined this appeal, and possibly even pushed Regavim to submit it. As far as these ideological settlers are concerned, all of life in Israel-Palestine is a negative-sum game, in which the overarching goal is to retain exclusive control of the entire country, while squeezing more and more Palestinians into smaller and smaller enclaves – and if possible push them out of the country altogether. It is a sad and immoral world-view, but unfortunately its holders are very close to the corridors of power nowadays.

At other places and times, many settlers at Sussya and elsewhere have extolled their “good neighborly relations” with local Palestinians, and complained that only the media, or human-rights activists, are seeing and brewing trouble where there isn’t any. Many settlers also repeatedly claim that they only wish to live peacefully on these sacred hills, not to lord over others.

However, this court appeal on which the entire settlement of Sussya is signed as a co-plaintiff, reveals a very different perspective. The plaintiffs view their neighbors who have lived in the area long before them, as illegitimate and criminal. They accuse their neighbors of guilt-by-association, in completely unrelated terror attacks that took place at other parts of the West Bank 20-30 km away from Susiya (clause 10), and in thefts of livestock from Sussya settlement, even though these were admittedly carried out by persons from Yatta (clause 11: “…it can be assumed that the thefts were aided and abetted by accurate information… collected by the A-Nawajeh, living in illegal structures and making observations into the settlement”).

What is more disturbing to us, is that the Sussya settlement leadership has no qualms about exploiting the settlers’ structurally privileged citizenship status and the Palestinians’ discriminated status as subjects of a military regime. In this appeal, the settlers explicitly attempt to leverage that regime to punish and evict their neighbors in ways that would have been impossible, had the two population groups enjoyed equal legal and political status.

The future vision of settlers and Palestinians living together as equals, is plausible in principle both for us and for many Palestinians. Unfortunately, the Sussya settlers in submitting this appeal, and in this appeal’s foul language, reject this vision outright.

——————————–

Frivolous lawsuits like this one can actually help the “Civil Administration”. The differences between the “Administration” and ideological-settler bodies like Regavim are only of style and nuance. Both the settlers and the “Administration” are determined to reduce and, if possible, eradicate Palestinian life in “Area C”, in the apparent hope of making permanent the Israeli control of this vast region. Unlike settlers, the “Administration” is bound by the need to maintain a facade of respectability and legalistic pretexts. Thus, the Regavim appeal can present the “Civil Administration” in the public mind as even-handed or pro-Palestinian, and exaggerate its disagreement with ideological settlers. Nothing could be further from the truth.

But amazingly, the court appeal itself presents concrete evidence that exposes this charade for what it is.

Clauses 40-49 deal with Regavim’s attempts to obtain information about Palestinian structures already destroyed by the “Civil Administration” for “security reasons.” The “Administration” refused to release detailed data, saying laconically that “all demolitions are due to security reasons”. Data were obtained by Regavim indirectly via other government arms. Here’s what they found (translation, emphasis and comments by Assaf):

44. In parallel, the plaintiff has obtained via a separate FOIA request the GIS layer containing all illegal-construction cases in the Palestinian sector. Combining the two sources brings to light the reality of “structures” destroyed by the Civil Administration in 2008-2011, allegedly for being a “security risk.”

[45. Data table ]

….46. These data show, that while the defendants claim all structures destroyed in the Palestinian sector in 2008-2011 were destroyed for being a security risk – out of 195 such structures, only 28 were actual buildings, while 51 “security risk structures” were cisterns, 68 “security risk structures” were sheds, chicken coops and livestock pens, and 12 “security risk structures” were improved agricultural fields.

47. This clearly indicates, that despite clear instructions from the government to focus on security-related demolitions, the Civil Administration avoids destroying such structures, and instead focuses on destroying cisterns, sheds, chicken coops, livestock pens and agricultural fields – in order to present a statistical balance with destruction in the Jewish [settler] sector.

48. It should be noted that from a separate FOIA request by the plaintiff about construction permits awarded in the Palestinian sector it turned out that in 2008, 74 such permits were issued, in 2009 six permits, and in 2010 only 7 permits were approved for the entire Palestinian sector of “Area C”. It is well-known that every year, thousands of structures are built in that sector… the message internalized by the Palestinian public is that there is no need to apply for permits…

It is rare to see far-right settlers, in an open legal document, confirm word-for-word what Palestinians and the human-right community have been arguing for years:

– That “security” is usually a ruse by Occupation authorities, used to mask the true motives,
– That recently Palestinians have been virtually blocked from obtaining building permits,
– and that these policies undermine any remaining semblance of legitimacy that the “Civil Administration” might have had a right to claim.

One might wonder how Regavim still thinks that this is somehow evidence for discrimination against what they call “the Jewish sector” – the state-funded, state-built settlements whose residents wield immense power and occupy several seats in the Israeli cabinet. One might also wonder, whether Regavim thinks that 150,000 Palestinians should be allowed to construct buildings to live in at all (the answer seems to be “no”) – or whether Regavim feels fine with the “Civil Administration” refusing to issue any permits to Palestinians whatsoever (the answer seems to be “yes, as long as they also make sure to destroy all those thousands of unapproved Palestinian structures”). The permit numbers in the appeal also confirm the escalation in anti-Palestinian “Area C” policies since the establishment of Netanyahu’s current government in early 2009. We have reported and analyzed this escalation from the start.

The Regavim appeal is a clumsy attempt to shift the debate towards how stringent or lax “Civil Administration” policies should be. However, the information presented, and the reality of unequal treatment as known to anyone with even a basic knowledge, turn their appeal into valuable supporting evidence for the following conclusions:

1. This outdated Israeli military body, the so-called “Civil Administration”, should not be allowed to run Palestinian life anymore, and

2. The situation of fully-privileged citizens living side-by-side with rightless subjects of military rule, is unacceptable and must stop.

We welcome the sudden interest of settler groups in fairness and government accountability. They should be forewarned, though, that the quest for the truth, fairness, transparency and good governance – if carried out properly to its logical conclusion – will most likely lead to outcomes diametrically opposed to their political goals.

Premiere of a Film Documenting Relationships between Israelis and the People of Palestinian Susiya

Tuesday, September 28th, brought us great satisfaction. On that day, we and many of our friends in Susiya had the pleasure of attending the world premiere of the film “The Human Turbine” at the Haifa International Film Festival.

Over a period of two years from 2008 to 2010, a film crew headed by director Danny Verete and producer Yehuda Bitton documented the evolving ties between the people of Susiya and the Israelis who visit them regularly activists in the Villages Group and the Comet-ME NGOs. The resulting hour-long film follows the various projects made possible by the cooperation between the locals and the Israelis, projects that include the production of sun- and wind-generated electricity for the Susiya families, plans for aid to local students and for professional training for young women, school transportation for the Susiya children, help and consultation in expanding water wells, and more.

The film was well received and viewers described it as deeply moving. Particularly effective is the film’s close attention to personal aspects of the work being done in Susiya. The filmmakers understood that the success of the projects described above is tied inexorably to the personal relations that have developed over the past several years between local residents and the Israelis.

We were fortunate to be able to invite almost twenty of our Susiya friends to join us for the premiere in Haifa—in spite of a general closure which totally prevented Palestinians from crossing the checkpoints to Israel for 10 days during the Jewish holiday of Sukkot. This was made possible by an invitation from the filmmakers and by our friend Buma Inbar, who obtained the special crossing permits. Following a lunch at the Haifa beach, we took in the panoramic view from atop Mount Carmel, and then watched the film together with our family members, the filmmakers, and other friends and guests.

At the final event of the Haifa Film Festival, the film “The Human Turbines” received an award on behalf of the Other Israel Film Festival in New York. As the Jury of this competition stated: “The film provides a rare glimpse in a world where humanity, compassion and cooperation provide hope for a different life in the complicated reality of the Middle East.” The film “The Human Turbine” is expected to be shown soon on Israeli TV’s Channel 8 and in other venues. We will keep you informed regarding opportunities to view the film, and we also hope to be able to send copies of the film, especially to our friends abroad.

UPDATE: The film will be screened at the Jerusalem Cinematheque on Saturday night October 30, at 7:30 PM. Also, copies are available for purchase; please email cara@ruthfilms.com.

First Biodigester Unit at Work in Susiya

Following the success of the Villages Group’s first environmental initiative – the renewable energy project, which has been now running independently for about a year under the banner Comet-ME – the Villages Group is now launching a second environmental initiative: Biodigester units for shepherd families’ use. These systems turn the family herd’s manure into bio-gas for the family’s cooking needs.

As mentioned in our previous post,  a month ago a team led by Yair Teller installed the first Biodigester unit at the residence of the family of  Ismail Nawageh in Susiya.  After a few weeks’ incubation period the manure in the Biodigester is by now producing enough gas, so yesterday it was connected to the Ismail family kitchen for regular use.

In the meanwhile, we also received the encouraging news, that the Arava Institute for Environmental Studies decided to adopt Yair’s project, and will send its Palestinian, Israeli and International students to help Yair in the installation of more Bidigester units in Susiya and elsewhere in the south Mt. Hebron region.

Strengthening Those Who Belong to the Land: Mahmud from Susya, the Organic Farmer

Mahmud from Susya got up one day from his depression, and built a very basic green house. With simple tools and techniques he succeeded to surprise us with excellent organic vegetables.
The vegetables are an essential addition to the family’s poor diet, based mainly on dairy products from the herd which is their main source of making a living. And while both herding and growing grains is restricted by the settlers/army, green-housing is a brilliant solution for growing food which does not require much land.
One day Mahmud discovered a vegetable disease on the leaves of his tomatoes. We could not help with the disease, but by suggested to finance for him an agricultural course. When he returned from his two months’ course at al-Arroub College north of Hebron, he also built a beehive.
Then, he turned out to be also a guide for Ahmad, from another family in Susiya. He taught him and helped him to build his own green house.
Meanwhile, since this area is a draught area, both by nature and by the Occupation (the regime prevents direct water supply), we supported 4 families in building 4 wells.
Recently we joined the building the first prototype home Bio-Gas system. The system was built by Yair Teller from the Arava Institute with our financial support. This system, the first one of its kind to operate in the Middle East, turns animals’ feces into gas for cooking needs. The previous success of the solar and wind based electricity systems which we, with COMET-ME, first built in Susiya two years ago, has motivated us to build this first prototype in Susiya as well.
All the above are actual examples of our way of supporting – strengthening the strengtheners of each community, both personally and communally.
We offer many aspects of support; even when financial, it is always a result of personal contacts and long standing relationships. In addition to Susya, we also maintain contacts with other communities in the region of south mount Hebron  such as Umm Fakara, Umm al-Kheir, al-Tuwani, Tuba and others.
The financial support for all the initiatives described above (in Susiya), was kindly provided by a family from London. We, members of the Villages Group and Susyans, thank them sincerely.

COMET on BBC World Competition

BBC CHALLENGE E-MAIL TEXT FOR COMET-ME Comet-ME Needs YOUR Vote – Today! Comet-ME proudly announces it is one of 12 finalists in the BBC World Challenge 2009. This global competition focuses on grassroots projects and small businesses worldwide that are taking effective, innovative action in environmental and socio-economic issues. In November, the winning project receives an award of $20,000! Comet-ME would use this prize to expand our project and to provide sustainable energy to another community. The winning project will be determined by online voting between 28 September 2009 and 13 November 2009, at http://www.theworldchallenge.co.uk/index.php

Comet-ME, a group of Israelis, Palestinians, and international volunteers, works closely with very poor communities in the occupied areas of Palestine. Under Israeli military occupation for 42 years, these people have no access (for political reasons) to the electricity grid. Our common goal is to help these people build sustainable energy systems using solar and wind power. Illumination, communication, and refrigeration increase their potential for generating revenue and reducing chronic poverty. We work with mutual interest and mutual respect, in the conviction that what we build together can begin to heal what has been destroyed. Each community owns its own project, and its local committee makes all relevant decisions; we provide materials and knowledge for building the energy systems. We foster proactivity in these weak communities: teaching and encouraging them to maintain their energy systems leads them toward economic empowerment. All of us believe that working together on such projects weakens the barriers of suspicion and hostility, ultimately facilitating the end of racism and segregation in the Middle East. Building energy systems in the occupied territories, we face daily danger to our work, both from Israeli settlers and from the Israeli army. It’s critical, therefore, that we become internationally recognized. International public opinion has significant impact in Israel. For this reason, we ask you to cast your vote for Comet-ME in the BBC World Challenge 2009. Please visit the website noted above during the voting period of 28 September through 13 November 2009, and vote for Comet-ME. And then, please visit our website at http://www.comet-me.org/index.html to learn more about the work we are doing with communities in the South Hebron Hills of Palestine. We hope you will forward this e-mail to all your friends, encouraging them to join you in casting a vote for Comet-ME.

Settlers Attack on Susya

On Wednesday, September 9th, 2009, the Israeli army destroyed a trailer located on “Flag Hill”, several hundred meters west of Susiya settlement. A short while later, around 11:00, dozens of settlers showed up at the small living area of the Balal family in the Palestinian hamlet of Susiya. These settlers violently attacked the three family members who were present on the spot – the father, Abu Nimer; the mother, Umm Nimer, and their daughter Alia. They also burst into the family kitchen and broke everything they found. The assailants also cut the electric cable supplying solar energy to the family home. Soldiers arriving on the spot, shortly after the settlers, stood aside and did nothing to interfere until the mother of the family was hit on the head with a blunt object. Only then did the soldiers intervene and made the settlers leave the Balal family home. The same assailants proceeded towards the residence of the Shiniran family, but were blocked there by members of this large family who had been alerted in time. While the assault against the Balal family was going on, about ten other settlers attacked the family’s livestock and the son who herded the flock – Issa. Several members of other families came out to help him. A fight ensued between them and the settlers, which fortunately ended without casualties or detainees. The settlers also attacked a local photographer as he recorded the goings-on with a camera belonging to ‘B’tselem’ human rights organization, and broke his camera. All these actions took place as apart of what the settlers name ‘the price tag’ – a premeditated, regular procedure by which the settlers respond to any attempt on the part of the government and the army to carry out evacuation or dismantling of outposts, immediately assailing the Palestinian population living in close the vicinity. After collecting ‘price tags’, the same settlers-assailants resumed construction in the area of “Flag Hill” outpost (picture no. 1) and it seems this outpost will grow considerably in the very near future. Other attached photos show Umm Nimer, the mother of the family who has been attacked several times this year and this time was seriously beaten in her back and head (picture no. 2); the Balal family kitchen most of whose utensils were shattered (picture no. 3); and a general view of the attacked family’s living quarters (picture no. 4).

On the same evening the team of COMET-ME came and fixed the solar system

Installation of solar systems for 6 more families in Susya

Dear Friends,
The last three months have been busy around here. Comet-ME was working on two issues in particular – fund raising and completing our work in Susya.
I will start with the good news: Comet-ME, using funds obtained from the German representative office in Ramallah and the Firedoll and Sparkplug foundations was able to complete the installation of solar home systems to all the families living in Susya. Most of July and the beginning of August were dedicated to the purchasing, construction and finally the installation of six more family solar systems in Susya and the upgrading of the community utility center we built in March. The installation itself was great. Very intense, and hot, but rewarding, with some of the families having to wait for their turn almost a year. The process took several days in which we worked with Susya maintenance team, the families and many of our friends (including a group from Engineers Without Borders – Israel).

On the left you can see the new system we installed with the Abu Malesh family whom we got to know while working on the installation of the utility center in March. The system there is a typical family system with three bulbs and an electricity socket to power a charger or radio. This time around we wired the electric cabinets ourselves, to reduce costs even further, and changed the operation voltage of the systems to 220V AC so as to allow the users the freedom from specialized DC equipment – they can now use regular light bulbs and appliances.
On the right you can see Noam trying to figure out which way is which with the turbine upgrade. The whole system is now more powerful then before and can power two refrigerators; a welcome addition two weeks before the Ramadan and the heat of the desert.

On the fund-raising front we had some success in the early summer when we were approved the three grants I mentioned above but, on the other hand, two substantial grant we were hoping to get now seem out of the question as the funding organizations themselves are under the burden of the economic crisis. We are now hard at work trying to develop new directions but it might take a while.
At this point you come into the picture – help us continue the work we do. Spread the word.

One more thing, last but most definitely not least. The BBC world challange is an annual competition for grass root organizations that bring social and environmental change. Comet-ME is very proud to be selected as one of the 12 finalists on the competition. The winner will be chosen by open internet voting that will start on the 28th of September. There is still some time to go but we will need each and every one of you to vote (for us, we hope) and get everybody you know to follow suit.

We have created a facebook account and a twitter account. Join us there so you can follow up on what we are up to and introduce us to your friends.

Yours,

Comet-ME

COMET-ME Alternative-Energy Project is BBC/Newsweek World Challenge Finalist

COMET-ME, our sister project which has developed out of Villages Group activities, has won prestigious global recognition from the BBC/Newsweek World Challenge 2009 competition.

The judges have chosen COMET-ME as one of 12 finalists. The project, which empowers rural and semi-nomadic Palestinian residents (right now, mostly in South Hebron Hills) by helping them set up independent wind+solar electricity generation units, and training them in installation and maintenance, will be featured in an upcoming BBC story.

The Independent has recently devoted an article to the project, apparently in view of their World Challenge recognition. Here is an excerpt:

For the extended Shineran family, dependent for income on the butter they sell, the electric churn and the large energy-efficient refrigerator they now run off the new system, have together raised sales income from £850 per month to £1,450.

We congratulate COMET-ME, its founder Noam Dotan and all the project’s volunteers, for a well-deserved success. We hope that it continues to grow.

Help us to help the People of Susya

The Villages Group is involved in Susya in different ways:
• The COMET renewable energy project ( http://www.comet-me.org/) –
This project is about to its next stage, this time with the help of the German Consulate and the Firedoll NGO.

• Transportation of children to school (from Susiya and elsewhere in the region) –
There is a need to buy a new school bus for the children of Susiya.
With the help of the US-Omen NGO we obtained $7,500 of the $12,500 needed for this purchase.
In addition, the cost of a driver’s salary, gas and other expenses amounts to some $13,000 per year. Of this sum, $7,500 is covered by the British Shalom-Salaam Trust.

• Professional courses for women –
Thanks to a donation of $12,000 from the Center of Emerging Future, we were able to send this year six young women from Susiya and another six from the area to professional courses.
Hopefully, we would be able to continue with this program also next year.

• Scholarships to students –
With the support of the US-Omen NGO, this year we were also able to give scholarships to five students from Susiya and twelve other students from the south Mt. Hebron area.
In order to continue this project, we need to raise $10,000.

• Susiya Summer Camp –
Last but not least, we obtained about $1,800 of the $2,200 needed for the camp.
The camp is due to take place next month.

Given the settlers’ aggression towards people in this region, the oppressive policy of the Israeli occupation forces (aimed to make the life of the local Palestinian residents unbearable), and the total neglect of this area by the Palestinian Authority – all these needs should be considered essential.
