A group of journalists from a Bangladeshi news agency investigate the activities of an NGO called Shidulai Swanirvar Sangstha (SSS) which supposedly runs a network of "boat schools" in the Sunderban delta region. These boat schools provide basic education and agricultural training to people in remote, disadvantaged regions of Bangladesh, and even fulfill some of their power needs (by providing them night-lamps charged using solar panels). SSS has received quite a bit of media attention (even in the West) and was recently lauded with million-dollar awards from funding agencies of the ranks of Bill and Melinda Gates foundation and UNDP.
The journalists claim that the whole busness of SSS is basically a sham. On paper, they claim to own and run a troupe of 88 high-tech boats (equipped with solar panels, PCs, DVD players and 1500-book libraries) but in reality, they seem to be in possession of just 5 boats (out of which only 2 are fully functional). Their executive director boasts that their system serves about 90,000 marginalized families in Bangladesh whereas only 0.5% of people in the area seem to know about the boat-school concept (let alone make use of it).
If the findings of this study are correct, it seriously brings into question the trustworthiness of the agencies which are backing the whole program (the article names 3 of them: Bill-and-Melinda Gates foundation, UNDP, Santa Fe Conservation Trust) and the methods they use to evaluate social welfare projects in general. I don't see any obvious holes in the article and I'd say the investigation seems to have been conducted very carefully and the analysis is quite rational.
