A/HRC/4/111 page 12 7. We call upon States, television networks and other mass media, both public and private, to work towards an agreement in applying a multiracial aesthetic standard and in producing programmes aimed at promoting the self-esteem of non-white ethnic and racial groups; 8. We appeal to States to develop and implement affirmative action policies in order to: (a) provide equal access to quality higher education establishments for indigenous and Afro-descendant students and also ensure that they stay on and successfully complete their courses; and (b) foster equality of opportunity in access to employment. Affirmative action policies will have to be adopted wherever necessary and wherever discriminatory practices are observed; 9. We request international cooperation and development agencies and States to ensure that programmes to combat social exclusion and poverty give priority to indigenous groups and those of African descent; 10. We urge States to promote effective measures for preventing and combating the crime of trafficking in persons and to develop assistance and protection programmes for victims; 11. We encourage States and civil society to promote exchanges of knowledge and experience on traditional communities of African origin; 12. We call upon States to establish and strengthen national institutions for the promotion of racial equality and the promotion and protection of the human rights of victims of racism, racial discrimination, xenophobia and all forms of discrimination and intolerance, particularly people of African descent, indigenous peoples, gypsies and migrants, and to provide them with sufficient resources to ensure effective action. Such institutions must work with civil society participation; 13. We request States to incorporate environmental issues into their health and education systems and to view environmental issues, access to drinking water and the right to a healthy environment in the context of health indicators; 14. We call upon States, international agencies, private enterprise and civil society to avoid any environmental discrimination occurring as a result of their work, with serious consequences for future generations. We also call upon all these actors to reflect on the fact that the vulnerable groups in the different regions who suffer from social discrimination obviously also suffer from environmental discrimination and racism; 15. We encourage States, particularly governmental bodies working on this issue, to coordinate their action, share their experiences on good practices and adopt a regional approach to international agencies and donor agencies and countries; 16. We call upon States to incorporate the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families into their national legislation and practice, as one of the basic instruments for combating racism and discrimination;
