A/HRC/33/49 and girls made more vulnerable by disability and age. Regulators should monitor whether such regulations are well interpreted, implemented and effective; (i) Ensure the gender-responsive water, sanitation and hygiene facilities are available in schools, hospitals, the workplace, market places, places of detention and public spaces like public transport hubs and public institutions, among other places. Laws and regulations must be developed, promoted and enforced and must serve to hold Governments and non-State actors to account; (j) Develop water, sanitation and hygiene approaches, programmes and policies that proactively and deliberately enable the meaningful participation of women at all stages of planning, decision-making, implementation, monitoring and evaluation. States and development partners must identify, acknowledge and remove barriers to participation in decision-making in respect of water, sanitation and hygiene initiatives and ensure that women are aware of their ability to participate; (k) Develop a gender indicator system to improve the collection of data disaggregated by sex and other relevant factors, which are necessary to assess the impact and effectiveness of policies aimed at mainstreaming gender equality and enhancing women’s enjoyment of their human rights to water and sanitation; (l) Monitor intra-household inequalities and the way in which inequalities based on gender become manifest in extra-household settings, including in facilities in public institutions; (m) Ensure that comprehensive data is collected on access to water, sanitation and hygiene management in respect of women and girls belonging to marginalized groups and living in marginalized areas, and support civil society in collecting data and in analysing, interpreting and monitoring results; (n) Complement quantitative data on water, sanitation and hygiene with qualitative methods, to improve understanding and interpretation of gender-related issues and to inform and validate survey methods and techniques. 78. In addition, the Special Rapporteur recommends that development cooperation entities ensure that external assistance from non-governmental organizations, development agencies and the private sector comply with human rights standards and include measures to eliminate gender inequalities in access. 21
