A/HRC/42/38 (b) States should give due attention to monitoring the structural obstacles faced by persons of African descent in many regions. 119. States should adopt mixed approaches to data collection in order to capitalize on existing resources. They could do so by using mass media and communication tools as resources for data collection and by building networks of opinion leaders (for example, traditional and religious leaders, including women leaders) who could gather information while ensuring the inclusion and active participation of disadvantaged groups. 120. States, individually and collectively, should use local capacities to conduct evaluations and should promote the expertise developed by civil society networks specialized in evaluation. Regional and international levels 121. States reporting on their commitments in relation to the Paris Agreement on Climate Change, the Sendai Framework for Disaster Risk Reduction 2015–2030, the Addis Ababa Action Agenda and the 2030 Agenda for Sustainable Development should expressly address how they have implemented the right to development. 122. Global and regional intergovernmental organizations should collaborate in their strategic planning to tackle issues related to the right to development. 123. States should exchange good practices on evaluating development policies and programmes. They should promote South-South cooperation on evaluation, including by reporting good practices in periodic reports and developing an online repository of promising practices. 124. States should conduct comprehensive and independent assessments of the environmental, social and human rights impacts of transboundary policies and projects to address the negative impacts that projects might have in multiple countries. The assessments should be embedded in the design of the policies or projects, with their costs budgeted in advance. The assessments should be either led by the communities concerned or have their full and effective participation or approval, and the outcomes of the assessments should be publicized. 125. With the technical assistance of international organizations, States should conduct systematic human rights impact assessments on trade agreements to avoid causing harm to the environment and human rights. 126. Environmental and social safeguards should be enforceable and States should have a role in setting such safeguards, gathering the necessary information and determining whether private enterprises and investment banks are complying with them. Given that most international financial institutions are public institutions, States should hold them accountable to regional and international legal standards. 127. Governments and international organizations funding development programmes should not impose conditionalities on beneficiary Governments since doing so could have adverse unintended effects on the population. This is particularly true when the conditionalities weaken human development policies. Rather, when seeking to initiate development programmes in countries where the government does not respect rights, funders should choose alternative implementing partners (for example, civil society). United Nations entities and mechanisms 128. Special procedures mandate holders and other international human rights experts should engage with emerging development banks in order to provide guidance and advice on how they can promote a rights-based approach to their activities, particularly as these financial institutions look to provide an alternative to the Bretton Woods model of development financing. Non-State actors 129. Development banks should respect environmental and social safeguards. They should not attempt to avoid them by financing projects through third entities. Specifically: 15
