elderly people are increasing. According to United Nations projections, 72 per cent of the population over 60 years of age will be living in developing countries by the year 2025, and more than half of that population will be women. Care of children, the sick and the elderly is a responsibility that falls disproportionately on women, owing to lack of equality and the unbalanced distribution of remunerated and unremunerated work between women and men. 31. Many women face particular barriers because of various diverse factors in addition to their gender. Often these diverse factors isolate or marginalize such women. They are, inter alia, denied their human rights, they lack access or are denied access to education and vocational training, employment, housing and economic self-sufficiency and they are excluded from decision-making processes. Such women are often denied the opportunity to contribute to their communities as part of the mainstream. 32. The past decade has also witnessed a growing recognition of the distinct interests and concerns of indigenous women, whose identity, cultural traditions and forms of social organization enhance and strengthen the communities in which they live. Indigenous women often face barriers both as women and as members of indigenous communities. 33. In the past 20 years, the world has seen an explosion in the field of communications. With advances in computer technology and satellite and cable television, global access to information continues to increase and expand, creating new opportunities for the participation of women in communications and the mass media and for the dissemination of information about women. However, global communication networks have been used to spread stereotyped and demeaning images of women for narrow commercial and consumerist purposes. Until women participate equally in both the technical and decision-making areas of communications and the mass media, including the arts, they will continue to be misrepresented and awareness of the reality of women’s lives will continue to be lacking. The media have a great potential to promote the advancement of women and the equality of women and men by portraying women and men in a non-stereotypical, diverse and balanced manner, and by respecting the dignity and worth of the human person. 34. The continuing environmental degradation that affects all human lives has often a more direct impact on women. Women’s health and their livelihood are threatened by pollution and toxic wastes, large-scale deforestation, desertification, drought and depletion of the soil and of coastal and marine resources, with a rising incidence of environmentally related health problems and even death reported among women and girls. Those most affected are rural and indigenous women, whose livelihood and daily subsistence depends directly on sustainable ecosystems. 35. Poverty and environmental degradation are closely interrelated. While poverty results in certain kinds of environmental stress, the major cause of the continued deterioration of the global environment is the unsustainable patterns of consumption and production, particularly in industrialized countries, which are a matter of grave concern and aggravate poverty and imbalances. 36. Global trends have brought profound changes in family survival strategies and structures. Rural to urban migration has increased substantially in all regions. The global urban population is projected to reach 47 per cent of the total population by the year 2000. An estimated 125 million people are migrants, refugees and displaced persons, half of whom live in developing countries. These massive movements of people have profound consequences for -13-
