An audit by an autonomous government office leaked last month found "significant deficiencies", including a lack of trained manpower, little transparency or monitoring, and corruption.

Just 3% of registered households audited received 100 days of employment. The average was just 18 days.

On 1 April, the government will expand the scheme to cover the entire country, something Dreze describes as "one of the biggest organizational challenges any government has ever faced". The audit should have been a "useful wake-up call"-if anyone was listening. "Let it not be said, a few years from now, that this extension took place appropriately on April Fool's Day," Roy, Dreze and Dey wrote.

Others are less forgiving.

The Centre for Environment and Food Security, an independent think tank, said a survey of 100 villages in impoverished eastern Orissa state showed about 75% of funds had been "siphoned and pocketed by government officials" in an organized way.

Inflated records and forged documents allowed bureaucrats to claim money for work that had simply not been done and for employment that had never been granted, it said.

"Only leakages and crumbs have reached the rural poor of Orissa," it concluded. "This scheme has become less of employment guarantee scheme for the hungry and poor and more of a money spinning machine...for Orissa's sarkari babus (bureaucrats)."

The report's author, Parshuram Rai, said a just concluded study in Madhya Pradesh had reached similar conclusions, with between 55% and 75% of funds missing.

When a Reuters team travelled to Bihar, it was hard to find any work taking place at all. Officials in Musahari subdistrict, home to more than a quarter of a million people, said just 20 small projects were under way.

Their most impressive showcase, the dirt, or kutcha, road in Sheikhpur village, employing, at most, 16 people. Rajesh Kumar Chaudhry was put in charge of the scheme in Musa hari two months ago and was doing his best to put people to work. But the programme's design was not making it easy.

Sixty percent of the money has to be spent on unskilled labour, leaving precious little for skilled labour or materials.

That meant pucca, or permanent, roads or buildings such as schools or clinics were pretty much out of the question, he said.

"We can only use soil, not plaster or cement. This district is flood-prone, and it would be good to build a raised platform for people during the flood period, but that needs a lot of soil-and that is not available here." Workers were hard to find, he said, with wages of just Rs81 a day little attraction.

"Work in godowns and construction work pays them more," he said.

Bureaucrats across the country don't always have the expertise or local knowledge needed to design relevant projects. In Haryana state, the audit says, hundreds of ponds were dug which do not collect or retain water.

Manoj Rai of research and development organization Pria said his survey showed bureaucrats asked for bribes to approve work done under the scheme or release funds needed to pay wages.

"We were joking that if you need a billion rupees for implementation, you need 30% for bribes," he said.

Dreze says it has been much more of a success in states with better governance, including Rajasthan and Andhra Pradesh, and is finally taking off in vast, densely populated Uttar Pradesh.

The publication of "muster rolls" in villages and on the Internet discourages false reporting. Dreze says the scheme needs to be tightened up rather than abandoned, a view shared by many who work in rural India, including Pria's Rai. "If 6% of Indians are getting 100 days of work, this is a very big thing to happen," he said. "But the money available for this scheme is so great, it can provide work for 60% not six."
