- 36 - 80. A satisfactory programme of activities is of crucial importance for the well-being of prisoners. In this context, the Prison Law enshrines the right of both remand and sentenced prisoners to educational, sports and cultural activities. In particular, it stipulates that access should be facilitated to education at all levels (adapted, as necessary, to the needs of foreign prisoners), to vocational training (leading to the acquisition of recognised qualifications), and to supervised sports activities. As regards work, prisoners may inter alia be employed in the general services of the prison, or in agricultural and industrial production units in prison, and may be authorised to work on their own account. The law also includes provisions on remuneration for work and other benefits (e.g. remission) resulting from participation in the activities organised in prison.16 Once again, the CPT can only applaud the laying down of these standards and particularly welcomes the recognition of the right of remand prisoners to activities. 81. Alicarnassos and Malandrino Prisons provided some form of organised activity to about half of their inmates, and Khania Prison to about a quarter of prisoners. As regards Korydallos Prison for Men, in 1993 the CPT described the prison regime as being rich in out-of-cell time but poor in activities (cf. CPT/Inf 1994 (20), paragraphs 108, 109 and 120). Despite efforts made by the authorities to develop activities (cf. CPT/Inf (2001) 19, pages 105-106 and 113), the situation remains basically unchanged; at the time of the 2001 visit, Korydallos offered some form of activity to a mere 17% of the inmates. The activities which were available in all four establishments often involved only a small part of the day or occasional work, and were mostly of a monotonous nature. In short, the vast majority of inmates were being offered nothing remotely resembling a regime. In this connection, it should be stressed that the question of provision of a programme of activities in prison is often linked to the problem of overcrowding; significant and lasting progress on the former is dependent upon successfully tackling the latter. Further, the CPT recognises that the provision of organised activities in prisons where there is a high turnover of inmates (e.g. Korydallos) poses particular challenges; however, it is not acceptable to leave prisoners to their own devices for months at a time. 82. The CPT recommends that a thorough examination of the means of improving the activities programmes in Alicarnassos, Khania and Korydallos Prisons be undertaken without delay and that fuller programmes (including education, recreation and sports activities, and work) be introduced as overcrowding is reduced. 16 Cf.
