Promoting niche markets through denomination of origin, eco-labelling, fair trade, organic and slow food initiatives, geographic indication, globally important agricultural heritage systems, and one-village-one-product intiatives may be particularly useful. Therefore, PGRFA include both farmers'varieties/landraces and modern cultivars of staple crops as well as NUS.The development and implementation of policies are a key component in promoting NUS/FSF into agricultural production systems (FAO, 2015a). Following this, the Rome Declaration on Nutrition included the call to "Promote the diversification of crops including underutilized traditional crops, more production of fruits and vegetables, and appropriate production of animal-source products as needed, applying sustainable food production and natural resource management practices" (FAO, 2014a). These commitments have become even more compelling with the imperative of achieving the SDGs by 2030. In general, in developing countries, the attainment of this objective even for staple crops, and more so for NUS, remains a seemingly intractable problem.
