Özet: Understanding the possible pattern of future ecosystem services can provide a systematic foundation for environmental resource management. This is vital towards science-based policy design, formulation, implementation, and review for the ecologically sensitive regions of the world such as the semi-arid West Africa. Therefore, the overarching objective of this study was to uncover the future ecosystem services of the Sokoto-Rima basin, particularly crop production (CP), seasonal water yield (SWY), habitat quality (HQ), and nutrient retention ratio (NRR) using InVEST software. Future (2050) land cover was constructed based on 2002, 2012 and 2015 Climate Change Initiative (CCI) remotely sensed data of the European Space Agency (ESA) using the artificial neural network algorithm of QGIS software. Results showed that CP averaged at 1.5 to 2.6 tons/km2, indicating a low crop yield; annual SWY averaged at 464.64 mm, showing a low flow status; roughly 73% of the basin have low HQ; and NRR remains in the low category throughout the period of study. This suggests that scenario-based further assessment of ecosystem service interactions could be vital for sustainable land use policy.
