Abstract: Farmland ecosystem services (FESs) are closely intertwined with the achievement of sustainable development goals (SDGs), which aim to maintain ecological balance, enhance agricultural productivity, and increase overall human well-being. However, the FES supplydemand gaps in rainfed and irrigated farmlands, as well as their relative contributions to SDGs, remain uncertain. Data from the Coupled Model Intercomparison Project Phase 6 (CMIP6) were employed to determine the spatiotemporal variations in FES supplydemand gaps across Central Asia from 1995 to 2099. Then, the natural and socioeconomic factors influencing the coordination of the FES supply and demand were explored. Finally, SDG scores of farmland ecosystems in Central Asia were calculated and predicted under the SSP245, SSP370 and SSP585 scenarios. The research results revealed that grain production and soil conservation services demonstrated a considerable supply surplus and a notable demand deficit and that the water yield exhibited a considerable imbalance (supply SDG15 (34.51 %–36.74 %) > SDG6 (27.88 %–30.65 %). During the 2050 s and 2090 s, the overall SDG index values of agroecosystems in Central Asia were projected to decrease, particularly under the SSP585 scenario (68.11 %–66.37 %). This decline was especially notable for SDG14 and SDG12 in the upper Amu Darya and Syr Darya basins. To promote these SDGs in the above regions and achieve sustainable agricultural development, policymakers should prioritize balancing the supply and demand for water production and sand fixation services.
