Mamar is an artificial oasis that provides a base for natural resource conservation in West Timor. The uniqueness of Mamar is its application in arid natural environments through a sustainable local leadership system, and it has a positive impact ecologically, economically, and socially. However, the Mamar system needs to receive more attention from the government in conserving natural resources. Such studies like Mamar's have been conducted elsewhere in Indonesia under different names, but they were applied in areas with wet and relatively fertile climates. Also, research on Mamar has been carried out by several parties related to the function of Mamar economically and the condition and structure of Mamar physically and biologically. However, research on Mamar related to the Construction of Environmental Leadership with local community behavior in Mamar based natural resource conservation has never been done. This research aims to analyze the construction of environmental leadership in natural resource conservation practices based on the Mamar system. This research was conducted through qualitative methods and critical interpretive approaches, with data collection techniques in the form of observation and interviews.
The results indicate that Mamar based natural resource conservation in West Timor has positively and significantly impacted social, economic, and ecological aspects and has lasted for hundreds of years since the 17th century. It is done through the mechanism of Environmental Leadership Control through a strong, effective, and sustainable Local Leadership Role in Amarasi West Timor, with Local Leaders called Atupas, Mataf, Tobe, and Temukung.
