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.

  • Postharvest management, value chain upgrading, market and business development.
  • Food loss and waste assessment and reduction, particularly along value chains of perishable crops.
  • Public and private standards in domestic, regional and international trade of agricultural and livestock products and implications for smallholder farmers’ market access.
  • Establishment and management of partnerships between research organizations and government agencies, non-governmental organizations, private sector and service providers, including multi-stakeholder innovation platforms.
  • Intellectual, technical and management leadership of interdisciplinary teams involving both biophysical and social scientists.
  • Proven experience in strategic planning, project/program management, financial oversight, and M&E to ensure delivery of expected results and outcomes in a cost-effective and timely manner.
  • Member of the NRI Development Studies Research Group.

Senior Scientist in the “Market Intelligence and Product Profiling”, a One CGIAR Initiative (2022-2030) which aims to provide data, information and insights to inform decisions that will prioritize and align CGIAR investment in breeding pipelines and seed systems.

Senior Scientist and Country Focal Point in the “Nature Positive Solutions”, a One CGIAR Initiative (2022-2030) which aims to re-imagine, co-create, and implement nature-positive solutions-based agrifood systems that equitably support local food and livelihoods, while simultaneously ensuring that agriculture is a net positive contributor to nature.

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.

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.
