Article begins 1947–2026 Joachim Voss, whose research and leadership expanded understanding of sociocultural dimensions of agriculture and development, died April 5. He was 79. An eminent scholar of Central Africa and Southeast Asia, he also served many years in distinguished international leadership roles. Voss had a highly distinguished career as a sociocultural anthropologist who worked outside the discipline in international development research institutions. He served as director general of the Centre for International Agricultural Research (CIAT, now known as Alliance of Bioversity International, 2000–2007), and on the Board of Governors at SeedChange (2014–2020). He had earlier served as the head of research and representative to the Consultative Group on International Agricultural Research (CGIAR) at the International Development Research Center (IDRC Canada, 1988–2000) and on the selection committee of the Rockefeller Foundation’s “RockyDocs” for five years in the early 1990s.…
