text: in states of homelessness or inadequate housing must be prevented and rectified through the adoption of an instrument on housing rights; (n) Environmental issues directly linked to housing rights; this would include floods, landslides, pollution of land, water, air, etc. The need for sustainable planning of human settlements and housing must be recognized; (o) Specialized housing needs: the housing needs of the elderly, the disabled, the terminally ill, children, women, and other groups must also find recognition; (p) A legal definition of the term "adequate housing": such a definition could be based on six possible criteria: (i) an adequate physical structure; (ii) the site on which it is built; (iii) the infrastructure and facilities provided to it; (iv) the cost; (v) the location; and (vi) type of tenure. 119. The process leading up to an instrument on housing rights could provide a good basis for directly incorporating the use of indicators into the standard-setting process, as well as exploring further and elaborating State obligations of conduct and result in the realm of housing rights. The State has the duty to refrain from actions such as eviction, discrimination in the housing sector and imposition of measures limiting people's ability to participate in and control their housing resources. However, housing rights necessarily imply the obligation of the State to provide, for instance, the physical infrastructure and basic services inherent within the right to housing and create mechanisms to allow access to land, building materials and financing. Moreover, the drafting process could enable new ideas to emerge relating to the practical issues of enforcement, monitoring and justiciablility surrounding this right, issues also much in need of substantiation and improvement in this context. 120. The Special Rapporteur would appreciate comments from the Sub-Commission conceiming the prospects of further standard-setting in the field of housing 
analysis: The text primarily focuses on the rights and needs of individuals in relation to housing, including the prevention and rectification of homelessness, environmental issues, specialized housing needs, and the definition of adequate housing. It also discusses the role of the State in providing and protecting these rights. Given this focus on human rights and social issues, it seems likely that the most fitting category would be related to human development.
