Abstract Tree-crop diversification is increasingly adopted in tropical agricultural landscapes as a resilience strategy amidst fluctuating commodity markets, environmental change, and policy shifts. However, its spatial implications at the landscape level remain underexplored. This study examines structure dynamics of mosaic eastern Côte d’Ivoire, region characterized by heterogeneous landscapes, response to tree-crop trends their for sustainable management. Using multi-temporal Landsat imagery (1986, 2016, 2023), remote sensing classification with Random Forest algorithm, metrics, we evaluated changes land-use/land-cover (LULC), composition (diversity, regularity), configurational heterogeneity (complexity fragmentation). Results reveal substantial increase rubber plantations (net gain 50.35%), concurrent declines cropland (−147%), cocoa (−45.28%), sparse vegetation (−61.48%). Although diversity increased slightly (Shannon index: 0.99 1.07), fragmentation intensified, mean patch size decreasing 12.3%. While introduced new compositional complexity, it often manifested monoculture expansion rather than ecologically restorative land-use. The resulting structural transformations, high edge densities smaller, isolated patches, suggest diminished functional connectivity natural habitats increasing ecological vulnerability. These raise critical questions about long-term sustainability current land-use trajectories. We argue that diversification, while enhancing economic stability, can erode without integrated landscape-level planning intervention. recommend landscape-scale strategies promote agroecological corridor conservation, inclusive governance mitigate maintain multifunctionality these rapidly transforming landscapes.
