text: should be revised to make it clear that the geographical scope of this ' provision is related to draft articles 12 and 13, in other words, to the total environment traditionally occupied or used by thèse peoples, and over which they enjoy rights of ownership or control. 72. As for the question of environmental protection or conservation, the , Chairman/Rapporteur believes this concem is covered by the words "without adverse discrimination". Non-discriminatory measures would be permissible, if necessary to préserve habitats or species. At the same time, the second sentence of this draft article would imply that States should restrict indigenous peoples' activities only as a last resort, when no alternative conservational measures are possible. 73. Lastly, the Chairman/Rapporteur is of the view that this draft article is permissive rather than restrictive in nature - that is, it leaves to the indigenous peoples themselves-.the choice of traditional or other forms of : économie activity. It would in no way limit their right to benefit from progress in science and technology, or to adopt alternative forms of économie life. Draft article 19 "The right to spécial State measures for the immédiate, effective and continuing improvement of their social and économie conditions, with their consent, that refleet their own priorities." 74. One govemment observer noted that States are unlikely lo have limitless resources available to them, and suggested that this draft article be reworded in more realistic terms. i 75. The Chairman/Rapporteur takes into considération this concem, and ' underscores her belief that this obligation, like the obligations contained in the International Covenant on Economie, Social and Cultural Rights, would be given progressive effect - that is, States would npt be required to achieve everything at once, but only to take concrète steps to enhance the enjoyment of thèse rights, to the extent of their resources.

analysis: This text appears to be discussing the rights of indigenous peoples, specifically their rights to traditional lands, economic development, and environmental protection. It also touches on the theme of states' obligations to improve the social and economic conditions of indigenous peoples. The language used is formal and diplomatic, suggesting that it is part of a UN document or report.
