As a former, and by many accounts successful, finance minister, Benjamin Netanyahu presumably knows his way around economics. So when the Israeli prime minister says he will work to provide the Palestinians with economic, if not political, independence, might that not suggest his hard-line government understands that a prosperous Palestine would be an important first step towards a more stable Middle East?

Not according to the World Bank, which last week issued the latest in a series of reports about how the Israeli government is systematically pre-empting the evolution of a viable Palestinian economy. The 154-page “Assessment of Restrictions on Palestinian Water Sector Development” is written with a blandness suited to the banality of this particular Israeli outrage. The report offers a detailed look at how Israel deprives the West Bank and Gaza of the most basic commodity for human survival, a deficit that consumes a growing share of Palestinian GDP.

The report is another indictment, as if one were needed, of the now-defunct Oslo Accords. Just as Oslo lacked adequate mechanisms to enforce Israeli pledges to sharply reduce its occupation of Palestinian land, so too has Israel been allowed to abrogate its commitment to revise interim agreements relating to water systems in the Arab territories it controls.

Instead, according to the World Bank report, Israel has aggrandised a growing share of available water supplies while intensifying Palestinian reliance on Mekorot, the Jewish state’s national water carrier. The report states that Israel, without the approval of the Israeli-Palestinian Joint Water Committee (JWC) – a legacy of the Oslo process – draws more than 50 per cent from the aquifers that support both the West Bank and Israel beyond what it is authorised under the accords. Needless to say, Palestinian protests of such violations are routinely ignored, according to the report.

The Israeli-Palestinian conflict is as much about resources as it is about land. It is no coincidence, for example, that West Bank settlements are located on top or near groundwater wells, a strategy that dates back to the earliest days of the settler movement. But the situation has worsened over the past decade, when Israel began restricting mobility in the West Bank and Gaza following its “withdrawal” from certain Palestinian areas under the terms of Oslo. Palestinians must now pay an estimated 8 per cent of their household budgets for adequate water supplies, about double the globally accepted standard. That is beyond the capacity of many Palestinian families, and revenues have fallen precipitously in the parts of the West Bank under Palestinian administration.

Rural villagers who are unconnected to the water grid must allocate up to 20 per cent of their household income for tanker-born drinkable water, an increasingly expensive enterprise due to the proliferation of Israel-controlled checkpoints, the massive, serpentine security wall and other barriers to mobility throughout the West Bank. The World Bank estimates the added expense of transporting water by tanker amounts to about 1 per cent of the Palestinian GDP. In Gaza, water availability has reached “crisis levels”, while utility revenues have collapsed and tax collections rates are down 20 per cent.

Water quality is deteriorating and there is growing evidence of rising water-related diseases. The public health costs of waterborne illness for children below the age of five alone is 0.4 per cent of GDP, the report estimates. The environmental impact, meanwhile, is devastating. Sanitation and sewage systems have been badly neglected due to unstable security conditions and Israeli restrictions on movement. Sewage is returned untreated into lagoons, wadis and the sea or seeps into the soil where it ultimately contaminates aquifers. In rural areas, septic tanks are not properly emptied, while Israel’s settler population routinely dumps raw sewage on to Palestinian soil.

Just as Israel controls the borders, roads, air and sea ports, airspace and export revenue on which the Palestinian economy vitally depends, so too does it control Palestinian water resources via Mekorot, an unhealthy reliance intensified by Israeli over-extraction of available supplies. Mekorot’s dominant role in water distribution, the report states, “makes [the West Bank and Gaza] vulnerable to Israeli decisions and interventions, and may increase commercial risks and costs”.

The report concludes with a raft of proposals that might ameliorate the crisis, all of which require Israeli co-operation and consent. It suggests, for example, the wholesale reform of the JWC, which is strongly biased in Israel’s favour due to its disproportionate levels of power and capacity. Only half of the US$121 million (Dh444.4m) worth of Palestinian-proposed projects have been approved since 2001, while all but one mooted by Israel have been granted. Israel, the report lays out, routinely decides unilaterally how regional water sources will or will not be developed.

An economy without access to clean water supplies is by definition unsustainable. Mr Netanyahu either fails to understand this or his commitment to Palestinian economic independence is nothing more than political palaver. Either way, Palestine’s man-made water crisis should be at the top of the agenda when the Israeli leader meets his US counterpart early next month.
