In the case of the PDI, workers are employed full-time and receive a salary of around TND 320 per month, with no limit on the duration for which they can remain in the programme. In the case of the PDCR, only a few days of work per month are provided, and a salary of TND 120 is paid. While the PCRD is implemented nation-wide, the PDI operates only in 90 of the 264 delegations, selected on the basis of certain social, economic and environmental criteria. In 2012, over 78 000 people participated in these programmes, however eligibility criteria for participation are not clear.
