Phosphorus sustains global food production and is, therefore, of crucial importance to human nutrition and health. However, its mismanagement can lead to water pollution and environmental degradation in addition to low crop yields. In many parts of sub-saharan Africa, phosphorus deficiency constrains agricultural productivity and exacerbates food insecurity. Despite these challenges, phosphorus remains a fragmented topic in global and African policy. To address these issues, the 8 th Sustainable Phosphorus Summit (SPS8) was convened in Africa for the first time. SPS8 took place in Accra, Ghana, between 30 th September and 3 rd October 2025. The Summit was an international collaboration, with co-conveners from the Council for Scientific and Industrial Research (CSIR) – Ghana, the Forum for Agricultural Research in Africa (FARA), The UK Centre for Ecology & Hydrology West Africa Office, Lancaster University and Rothamsted Research. In this paper, we give a detailed overview of the key messages and insights that emerged from highlight talks, lectures, working groups and field trips. We also discuss and reflect on the challenges of delivering an inclusive summit, from designing solutions to benefit-sharing. SPS8 demonstrates that inclusive, cross-sector knowledge-exchange events are crucial to support and enable phosphorus sustainability on the continent of Africa and globally and to enable the next generation of interdisciplinary phosphorus researchers.
