29. In order to give effect to the provisions of article 9 of the Covenant, States parties must guarantee the provision of survivors’ and orphans’ benefits on the death of the breadwinner who was covered by social security or receiving a pension. 30. Furthermore, as already observed in paragraphs 20 and 21, in order fully to implement the provisions of article 9 of the Covenant, States parties should, within the limits of available resources, provide non-contributory old-age benefits and other assistance for all older persons, who, when reaching the age prescribed in national legislation, have not completed a qualifying period of contribution and are not entitled to an old-age pension or other social security benefit or assistance and have no other source of income. Article 10: Protection of the family 31. On the basis of article 10, paragraph 1, of the Covenant and recommendations 25 and 29 of the Vienna International Plan of Action on Ageing, States parties should make all the necessary efforts to support, protect and strengthen the family and help it, in accordance with each society’s system of cultural values, to respond to the needs of its dependent ageing members. Recommendation 29 encourages Governments and non-governmental organizations to establish social services to support the whole family when there are elderly people at home and to implement measures especially for low-income families who wish to keep elderly people at home. This assistance should also be provided for persons living alone or elderly couples wishing to remain at home. Article 11: Right to an adequate standard of living 32. Of the United Nations Principles for Older Persons, principle 1, which stands at the beginning of the section relating to the independence of older persons, provides that: “Older persons should have access to adequate food, water, shelter, clothing and health care through the provision of income, family and community support and self-help”. The Committee attaches great importance to this principle, which demands for older persons the rights contained in article 11 of the Covenant. 33. Recommendations 19 to 24 of the Vienna International Plan of Action on Ageing emphasize that housing for the elderly must be viewed as more than mere shelter and that, in addition to the physical, it has psychological and social significance which should be taken into account. Accordingly, national policies should help elderly persons to continue to live in their own homes as long as possible, through the restoration, development and improvement of homes and their adaptation to the ability of those persons to gain access to and use them (recommendation 19). Recommendation 20 stresses the need for urban rebuilding and development planning and law to pay special attention to the problems of the ageing, assisting in securing their social integration, while recommendation 22 draws attention to the need to take account of the functional capacity of the elderly in order to provide them with a better living environment and facilitate mobility and communication through the provision of adequate means of transport.
