Abstract


ABSTRACT: The significance of having a payment scheme for ecosystem services (PES) for the purpose of watershed protection in order to develop a sustainable forest management is globally recognised. PES is an advanced financial tool to foster a platform for generating a source of income from ecosystem service users to ecosystem providers. More importantly, the involvement of households is vital for the successful implementation of PES programmes. Thus, this study aims to examine the willingness to pay for watershed protection services among households in the Langat Basin. Households around upstream, middle-stream and downstream segments of the Langat Basin were selected randomly to be studied and involved in face-to-face interviews. The Probit and Logit models in Contingent Valuation Method (CVM) were employed to assess household’s WTP towards watershed protection efforts of the Langat Basin. The mean for WTP of Upstream household is RM30.01 while middle-stream household’s WTP is RM33.07 compared to that of the downstream household, which is RM32.41. The households’ WTP shows an increasing trend from upstream to downstream households. These results offer a new insight and discernment between PES programmes and households’ WTP so as to develop a sustainable management for water-based ecosystem services.

ABSTRAK: Kepentingan mempunyai skim bayaran (PES) bagi fungsi perlindungan kawasan tadahan air untuk pembangunan pengurusan hutan secara mapan diiktiraf secara global. PES merupakan alat kewangan yang terkehadapan bagi untuk memupuk platform untuk menjana sumber pendapatan daripada pengguna perkhidmatan ekosistem kepada ekosistem pembekal. Lebih penting lagi, penglibatan isi rumah adalah penting untuk kejayaan pelaksanaan program PES. Oleh itu, kajian ini bertujuan untuk mengkaji kesanggupan membayar untuk perkhidmatan perlindungan kawasan tadahan air dalam kalangan isi rumah di Lembangan Langat. Isi rumah sekitar huluan, pertengahan dan hiliran di Lembangan Langat telah dipilih secara rawak untuk dikaji dan terlibat dalam temu bual bersemuka. Model Probit dan Logit dalam Kontinjen Kaedah Penilaian (CVM) telah digunakan untuk menilai WTP isi rumah ke arah usaha-usaha perlindungan kawasan tadahan air di Lembangan Langat. Min WTP isi rumah di bahagian huluan ialah RM30.01 manakala WTP isi rumah di bahagian pertengahan adalah RM33.07 berbanding dengan isi rumah di bahagian hiliran, iaitu RM32.41. WTP isi rumah menunjukkan trend yang meningkat dari bahagian hulu ke hiliran. Keputusan ini menawarkan wawasan baru dan pengertian antara program PES dan WTP isi rumah bagi membangunkan pengurusan mampan bagi perkhidmatan ekosistem berasaskan air.
