This paper presents a study conducted using the Multi-Criteria Analysis (MCA) to explore surface irrigation potential zones in the Didesa sub-basin of the Abay basin in Ethiopia. Physical land features, such as land use / land cover (LULC), slope, soil depth, drainage, and road proximity, along with climate factors like rainfall and evapotranspiration, and population density, were identified as criteria for the exploration. The analytic hierarchy process (AHP) is a powerful structured decision-making technique commonly used for complex multi-criteria analysis problems where multiple criteria need to be considered. The importance of the criteria was prioritised and ranked in the analytic hierarchy process (AHP). Five qualitative-quantitative based surface irrigation potential zones were identified, namely highly suitable (48.40%), moderately suitable (27.26%), marginally suitable (13.27%), not suitable (4.91%), and irrigation constraints (6.16%). The consistency of the AHP technique in the exploration of surface irrigation potential zones is evaluated by the consistency index at CI = 0.011 and confirmed the correctness of weights assigned for the individual key factor in the AHP. The accuracy of the potential zones generated in the AHP was evaluated with ground-truth points and a supervised LULC classification map. Moreover, a good agreement was made among the classes with the kappa index (KI = 0.93). Therefore, the application of the MCA for the exploration of surface irrigation potential zones was successful, and the results of the study will be useful to strengthen the irrigation in the explored potential zones.

Despite many studies and surveys on environmental friendly hotels, not many have applied the logistic regression analysis research technique. This study is a quantitative study applying this technique. It aims to explore key effect factors in tourists’ decisions to stay at environmental friendly hotels. This study should be useful for planning and policy-making in the hotel and accommodation marketing business to promote sustainable tourism. This study collected data from 400 tourists of various nationalities. They were selected through the purposive sampling method. Logistic regression was applied to the data analysis. The study found that certain variables (the overall attitude of tourists; those aged 30 and older; those with an educational level of graduate school and higher; reasons for traveling; especially from Europe and North America; and travel with families) affect the tourists in deciding to stay at the environmental friendly hotels. The results of this paper would be a managerial implication for hotel authorities around the world.

Pomimo wielu badań i ankiet dotyczących hoteli przyjaznych środowisku, niewiele osób stosuje technikę analizy regresji logistycznej. Niniejsze badanie jest ilościowym badaniem stosującym tę technikę. Ma na celu zbadanie kluczowych czynników wpływających na decyzje turystów na pobyt w hotelach przyjaznych dla środowiska. Badanie to powinno być przydatne w planowaniu i kształtowaniu polityki w branży hotelarskiej i marketingu mieszkaniowym w celu promowania zrównoważonej turystyki. W tym badaniu zebrano dane od 400 turystów różnych narodowości. Zostały one wybrane za pomocą celowej metody pobierania próbek. Regresja logistyczna została zastosowana do analizy danych. Badanie wykazało, że niektóre zmienne (ogólna postawa turystów, osoby w wieku 30 lat i starsze, osoby z wykształceniem co najmniej wyższym, powody podróży, szczególnie z Europy i Ameryki Północnej oraz podróże z rodzinami) wpływają na turystów decydujących się na pobyt w hotelach przyjaznych dla środowiska. Rezultaty tego artykułu byłyby implikacją zarządczą dla władz hotelowych na całym świecie.
