Context: It is well documented that a successful agricultural transformation is crucial for the economic progression of nations. While regions like Asia and Latin America have witnessed successful agricultural transitions, Africa faces unique structural and environmental challenges that hinder transformation. Current measures of agricultural transformation often fail to accurately reflect the true state of progress on the continent. Objective: This paper proposes a new framework, the Holistic and Inclusive Agricultural Transformation Index (HIATI) to more accurately assess and compare the progress of agricultural transformation in African countries. It aims to inform policy discussions and decisions by providing a holistic and comprehensive transformation index that captures both drivers and barriers to agricultural transformation. Methods: The HIATI comprises six dimensions including Agricultural Productivity and Efficiency, Structural Economic shifts, Market integration and value addition, Rural Infrastructure and Financial Services, Climate Resilience and Sustainability and Policy and Institutional effectiveness. HIATI was developed using standard practices in composite index construction which involved, (i) identifying key dimensions based on theoretical and empirical literature, (ii) selecting measurable indicators, (iii) normalizing data to ensure comparability, and (iv) aggregating indicators into a single index using a transparent weighting scheme. The indicators under each dimension were selected based on relevance, theoretical grounding and data availability. Using publicly available data from the World Bank development indicators, a combination of direct and proxy indicators was used. Data were normalised using min-max scaling and a weighted aggregation method was applied with weights assigned based on theoretical importance and empirical support. Depending on the HIATI overall score, countries are categorised in four stages of agricultural transformation including early, emerging, transitioning and advanced. The robustness of the index was tested through comparison with other indices and frameworks. Results and Conclusions: Study findings reveal some notable changes in the agricultural development stages of African countries. Between 2000 and 2020, the number of countries classified as being in the early transformation stage reduced from 21 to 7 while those in the emerging stage increased from 30 to 46. Among the 16 Countries that transitioned from early stage to emerging, Mali,
