In recent decades, the Hulu Langat Basin in Malaysia has been exposed to extensive changes in land use pattern and consequently hydrological conditions. Maintaining a reasonable balance between environmental currents and governmental/population demands is a difficult task. In this work, 3 land use scenarios were defined, which are the present (baseline), future, and water conservation plans. Weighted goal programming (WGP), integrated with the analytic hierarchy process (AHP), was used to optimize the baseline land use scenario with consideration of water conservation outcomes and future development trend. Three types of objectives were involved in the AHP-WGP approach, i.e. social, economic, and environmental. The values of environmental objectives were estimated using the optimized Soil and Water Assessment Tool (SWAT). Four planning alternatives were defined and formulated, i.e. A1, A2, B1, and B2. The AHP-WGP approach resulted in 4 optimized land development alternatives. In terms of the water conservation objective, alternatives A1 and B1 were more desirable than alternatives A2 and B2, respectively. However, due to the existing socioeconomic-environmental circumstances within the Hulu Langat Basin, alternatives B1 and B2 were more appropriate.

• 0.06 t ha −1 year −1
• The decision about which alternative is practical at the Hulu Langat Basin depends on the proposal of land use planners. However, based on existing socioeconomic-environmental conditions and development trends within the Hulu Langat Basin, alternatives B1 and B2 are more applicable.
• The preferential weights of 39%, 37%, 12%, 7%, and 5% were assigned for WYLD, SEDL, BIOM, SURQ, and NINC, respectively, using AHP. A CR value of 0.14 indicated that the set of judgments was consistent.
