Perhaps nothing better illustrates the soaring hopes and crashing disappointments of Gaza in the last 15 months than the experience of the Al Boh brothers.
Barakat Ramadan Al Boh, 53, sat and chatted this week outside his home in Beit Hanoun, which still bears the scars of bulldozer damage done by Israeli units which laid waste to the houses opposite during their lethal six-day incursion into the town.
Mr Al Boh recalled how, in September 2005, he had been recruited to harvest green peppers and tomatoes in greenhouses that had belonged to the departed Jewish settlers of Gannei Tal. Mr Al Boh is an experienced nurseryman who had beena foreman for more than 20 years, in charge of some 35 workers - until the intifada started in 2000. He had been unemployed since then, and was delighted to get the job in Gannei Tal.
"It wasn't much money, frankly, just 60 shekels (£7) a day, not really enough to make a living. But we were happy to be going to work. We were even more productive than the settlers, I can tell you. It was Palestinian, the project belonged to us, and we wanted it to succeed, to prove to the world that it could succeed."
He and his brother, Abdul Hakim, 42, were engaged by the Gaza Agricultural Project (GAP), launched with $14m (£7m) raised by James Wolfensohn, the former chairman of the World Bank, who had been appointed by President Bush as his special envoy for Gaza disengagement.
Mr Wolfensohn was determined to show that the withdrawal would benefit Palestinians in the Strip, and led the way by putting $1m of his own money into the project. At first it wasn't easy. A few at least of the greenhouses - many of which had produced high quality fruit and vegetables for the European export market - were burned or damaged by angry departing settlers; many more by Palestinians looting or taking destructive revenge against the former settlements. So the first job was was to rehabilitate 740 acres of nurseries, stores and packing stations.
"For two months we were out there cleaning it all up," said Mr Al Boh. But even after the plantation started, the nurseries were prey to regular raids by neighbouring Palestinian clans trying to rob them of valuable equipment.
Nevertheless, the project somehow succeeded in overcoming these obstacles. Plantation of cherry tomatoes, cucumbers, peppers and strawberries covered just under 600 acres. The GAP was able to provide desperately needed jobs not only to some 4,500 direct labourers, but also 1,000 indrect workers in engineering, agricultural supplies and other services. And this in a territory where unemployment was already at 33 per cent. (It rose to 41 per cent in 2006.) Production levels gradually reached an internationally competitive 120 tons a day. But because of closures imposed by Israel, citing security as grounds, especially but not only at the main Karni-Israel cargo crossing, only a small proportion of the harvest was likely to reach the outside world.
Frustrated by the delays and closures, Mr Wolfensohn, who has now long left his job, accused Israel of "foot dragging" over the crossings and said it seemed "loath to relinquish control, almost acting as though there has been no withdrawal." He persuaded Condoleezza Rice this time last year to broker a groundbreaking agreement between Israel and the then Fatah-controlled Palestinian Authority to open Gaza's crossings, including Karni.
The agreement had an immediate effect. The average number of outgoing trucks at Karni doubled to around 66 a day until the end of December. But the improvement was short-lived. The crossing was opened for only ten days in January; and, according to the UN's Office of Coordination of Humanitarian Affairs, there has been "little improvement" since then. The problem, as Ayed Abu Ramadan, the head of the GAP says, was that peak periods of crossing closures coincided first with the peak of demand in the European market and, in March and April, with the peak of the GAP's production.
The security concerns which Israel cited in defence of the closures were not baseless. On 26 April, a Palestinian group, believed to be members of the Dogmush clan, did attempt an attack on Karni. But this was foiled by Palestinian security. And no militant attacks, the UN report points out, were reported after that, until August 30, when the Israeli military announced the discovery of a tunnel leading to Karni. In the first quarter of 2006 - a crucial time for the project - the crossing was completely closed for 46 days, or 53 per cent of the working time. But the UN report points out that in 2004 and 2005, when the level of military activity in Gaza on both sides was much higher - including, Mr Abu Ramadan says, attacks on Karni - the crossing was closed for less than a fifth of the time.
The result of this was that just four per cent of the 12,700 tons of vegetables and fruit produced by the GAP actually made it out of Gaza. The vast bulk of produce rotted, or was handed out for free inside Gaza by the workers. The project was closed in early May, well before before the end of the season, because of the heavy losses became unsustainable in the absence of revenue.
