A/HRC/31/31 of these rights that are to be progressively realized, several components thereof need to be measured. Steps adopted to realize economic, social and cultural rights should be deliberate, concrete and targeted measures, making the most efficient use of available resources in order to move as expeditiously and effectively as possible towards the full realization of rights.12 13. The obligation of measurement is present to remind States that the notion of the progressive realization of economic, social and cultural rights is not a mere policy statement but needs to be thoroughly documented through the monitoring of: (a) Targeted steps taken at the national level; (b) Targeted steps taken through international assistance and cooperation; (c) The use of maximum available resources (including human, financial capacity and other types of resources of a State); 13 (d) The use of all appropriate means, including through appropriate laws, policies and programmes; (e) Clearly established time frames, indicators and benchmarks.14 14. For these purposes, a unified, well-designed national assessment and monitoring system needs to be put in place and regularly updated. Such a system makes policies, programmes and budgeting processes more efficient. It also helps to improve State reporting to various international human rights mechanisms. 15 Such a system needs to link the efforts made by States on the ground to measurable results felt by the concerned population groups and to corresponding human rights commitments. 15. Given the universality, inalienability, interrelation, interdependence and indivisibility of human rights, the assessment of a right cannot be entirely sectoral or linked with the improvement of one sole factor. Figures need to be contextualized. For instance, progress in the realization of the right to water cannot be only assessed by an increase in the number of access points. Other factors, such as affordability, the geographic distribution of these access points or their accessibility by various groups of the population, may also need to be included in the analysis. 16. In its periodic report to the Committee on Economic, Social and Cultural Rights, Viet Nam mentions a system of monitoring and evaluation indicators to assess the progress made in poverty reduction (see E/C.12/VNM/2-4, para. 343): The monitoring and assessment of the implementation of the objectives on growth and poverty reduction are carried out in all national, ministerial and local levels, 12 13 14 15 6 See Committee on Economic, Social and Cultural Rights, general comment No. 3. See Committee on the Rights of the Child, general comment No. 5 (2003) on general measures of implementation of the Convention on the Rights of the Child. Reference is made to the Commission on Human Rights resolution 1994/20 and subsequent resolutions that invite State parties to identify specific national benchmarks designed to give effect to the minimum core obligation to ensure the satisfaction of the minimum essential levels of each of the rights. The Special Rapporteur on the right to food stated in his mission to Nicaragua report, “that the law provides for the design, implementation and evaluation of a unified information system on food and nutrition security. This should help to address fragmentation in the area of food insecurity and vulnerability diagnosis, given the multitude of indicators used until now in the context of various mapping exercises ... The Special Rapporteur recommends that a unified system of indicators, targets and benchmarks be developed to monitor compliance with the State obligation to progressively realize the right to food.” (See A/HRC/13/33/Add.5, para. 34.)
