Economic valuation of attributes of Lake Tana: random parameter model

Technical efficiency of Fishers under the condition of water hyacinth infestation: Evidence from Lake Tana fisheries, Ethiopia

“…Such environmental conditions, water hyacinth, are not equally distributed 9 in all locations and the omission of such factors might lead to an upward bias in the estimated technical inefficiency [ 51 ]. Hence, the inclusion of such heterogeneous environmental production conditions could improve the reliability of the estimates [ 30 , 36 , 63 , 44 , 64 , 65 ]. Therefore, the variable water hyacinth was directly incorporated into the stochastic frontier model as an environmental variable.…”

Valuasi ekonomi Danau Poso mengacu market based approach

“…Poso adalah salah satu kabupaten di Provinsi Sulawesi Tengah yang menyimpan banyak potensi beberapa diantaranya adalah sebagai sumber air bersih yang dapat digunakan oleh masyarakat sekitar, penghasil energi listrik, rekreasi dan pariwisata serta sumber keanekaragaman hayati yang penting bagi ekosistem, seperti danau pada umumnya (Getnet and Taw 2021).

Valuation and effective management of the Dal Lake's diverse ecosystem using choice experiment method

“…A diverse range of valuation methods has been applied to value wetland services (Brander et al, 2006). These include the contingent valuation method (Siew et al, 2015; Ndebele & Forgie, 2017; Vidal Gimenez & Ruiz Mas, 2020; Eregae et al, 2021; Yavari et al, 2021), travel cost method (Musamba et al, 2012; Ghermandi, 2018; Shah & Islam, 2021), both contingent valuation and travel cost methods (Vidal Gimenez & Ruiz Mas, 2020; Alora & Nandagiri, 2015), choice experiment method (Dias & Belcher, 2015; Tan et al, 2018; Getnet & Taw, 2021) and benefits transfer method (Zhou et al, 2020; Badamfirooz et al, 2021) among others. Again, many studies have estimated only one out of many possible wetland attributes, like wetland biodiversity, and others have estimated more than one or the total economic value of wetland ecosystems.…”
