2. In imposing penalties laid down by general law on members of these populations account shall be taken of the degree of cultural development of the populations concerned. 3. Preference shall be given to methods of rehabilitation rather than confinement in prison. PART II. LAND Article 11 The right of ownership, collective or individual, of the members of the populations concerned over the lands which these populations traditionally occupy shall be recognised. Article 12 1. The populations concerned shall not be removed without their free consent from their habitual territories except in accordance with national laws and regulations for reasons relating to national security, or in the interest of national economic development or of the health of the said populations. 2. When in such cases removal of these populations is necessary as an exceptional measure, they shall be provided with lands of quality at least equal to that of the lands previously occupied by them, suitable to provide for their present needs and future development. In cases where chances of alternative employment exist and where the populations concerned prefer to have compensation in money or in kind, they shall be so compensated under appropriate guarantees. 3. Persons thus removed shall be fully compensated for any resulting loss or injury. Article 13 1. Procedures for the transmission of rights of ownership and use of land which are established by the customs of the populations concerned shall be respected, within the framework of national laws and regulations, in so far as they satisfy the needs of these populations and do not hinder their economic and social development. 2. Arrangements shall be made to prevent persons who are not members of the populations concerned from taking advantage of these customs or of lack of understanding of the laws on the part of the members of these populations to secure the ownership or use of the lands belonging to such members. Article 14 National agrarian programmes shall secure to the populations concerned treatment equivalent to that accorded to other sections of the national community with regard to-(a) the provision of more land for these populations when they have not the area necessary for providing the essentials of a normal existence, or for any possible increase in their numbers; (b) the provision of the means required to promote the development of the lands which these populations already possess.

Each Member shall, within the framework of national laws and regulations, adopt special measures to ensure the effective protection with regard to recruitment and conditions of employment of workers belonging to the populations concerned so long as they are not in a position to enjoy the protection granted by law to workers in general. 2. Each Member shall do everything possible to prevent all discrimination between workers belonging to the populations concerned and other workers, in particular as regards-(a) admission to employment, including skilled employment; (b) equal remuneration for work of equal value;
