India’s Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) is the largest public-works based employment programme in the world. Unanimously enacted by the Indian parliament in 2005, implementation began in February 2006. With an annual budget of six billion US dollars, it now supports some fifty million rural people – larger than the population of Senegal, Mali and Niger combined. This article focuses on the successes, issues and potential of the Act to improve the well being of workers and family farmers.
