Dr Diego Naziri joined the Natural Resources Institute (NRI) of the University of Greenwich in November 2010 as Market and Trade Economist. Before joining NRI he was Postdoc Fellow at the French Agricultural Research Centre for International Development (CIRAD) and at the Institut National de la Recherche Agronomique (INRA). Between 2006 and 2008 he was Research Fellow at the Agronomic Institute for the Overseas (IAO), the former technical-scientific branch of the Italian Ministry of Foreign Affairs for agriculture and rural development cooperation. Diego has more than 15 years of working experience in socio-economic research on transformation, sustainability and resilience of agri-food systems in the tropics. His main research interest lies in analyzing agricultural development problems and solutions with a focus on value chains, postharvest management, participatory methodologies for linking farmers to markets, crop-livestock-fish system integration, trade-related policies, agricultural innovation systems, innovation management and sharing, and management of complex research in development partnerships and multi-agency projects. Apart from his experience in conducting short-term research and consultancy in various low and middle-income countries (LMICs) on a number of different commodities, Diego has long-term overseas experience in Africa (Uganda), Asia (Vietnam) and Latin America (Brazil and Argentina) where he primarily focused on development challenges and opportunities of root and tuber crops. He obtained his Advanced University Degree (BSc/MSc) in “Agricultural Sciences” from the University of Turin (Italy) in 2001 and the PhD in “Cooperation for Sustainable Development” from the University "La Sapienza" of Rome (Italy) in 2006. He has been seconded to the International Potato Center (CIP) since 2014 and currently acting as CGIAR senior scientist based in Vietnam.

Principal investigator (P.I.) of FoodSTART+, a USD 2.2mln EU-IFAD funded initiative (2015-2019) to directly support IFAD’s strategic framework 2016-2025. It introduced, validated and scaled root and tuber crop (RTC) innovations for reducing food vulnerability and enhancing resilience in the region, primarily within the framework of large-scale IFAD investment projects in India, Indonesia, Philippines and Vietnam. http://www.rtb.cgiar.org/foodstartplus/

P.I. of RTB-ENDURE, a USD 3.6mln EU-IFAD funded multi-disciplinary project (2014-2017). It addressed key postharvest challenges of potato, sweetpotato, cassava and banana in Uganda by testing and validating technological and commercial innovations for improved postharvest management, expanded processing and targeting changing needs of emerging urban markets. Implementing team consisted of CIP, IITA, CIAT, Bioversity Int., CIRAD and several national partners, including 5 NARI, 3 Universities, 5 NGOs, local authorities, private firms and farmers’ organizations. Supervised three MSc students conducting relevant socio-economic research. https://www.rtb.cgiar.org/rtb-endure/
