In the four focus countries under RI-ZHC, the government played a pivotal role in organizing and facilitating the preparation of the country study on NUS at the national level, coordinated by the National Focal Point of the Zero Hunger Challenge, including the nomination of a competent national institution and expertise to undertake and finalize the country study on NUS. Nominated international experts were grouped by discipline to offer technical assistance to support the country on prioritization through interdisciplinary reviews. From an agricultural production and ecological perspective, the FAO Special Ambassador in the International Year of Pulses 2016, ICARDA, International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Bioversity International (Bl), the University of Western Australia (UWA), and the Chinese Academy of Tropical Agricultural Sciences-Tropical Crops Genetic Resources Institute (CATAS-TCGRI) joined as partners to support the international review on agricultural traits and climate-resilience of NUS. From a socioeconomic perspective, the International Centre for Integrated Mountain Development (ICIMOD), Crops for the Future (CFF), and the International Tropical Fruits Network (TFNet) served as partners to support the international review.
