Historical experiences: Mechanism of transfer: legitimatization 5 senses wisdom Knowledge generation: through Keraton people Institutionalized Structure: Visual:Indicators of Pranata Sultanate form of government mangsa (flowering of Mango Javanese Society’s structure tree, Kapok flower breaks, Response: managing natural resources, evacuation symbolization during eruption, spatial planning, time planning. Institutionalized dynamics: Patron-client etc.) Lampor = flood visual Visual of conservation and Conservation: the mountain and sea Internalization Myth: (relates to context of VRB) tree types Ratu Kidul: the Queen of South Java Sea ruler of Temporal experiences Merapi eruptions, seasonal spritual kingdom, the lampor ( Touch: indicators of patterns Javanese calendar Merapi : ancestors place pranatamangsa Nature dynamics: Volcano-river basin-Sea Rituals: relates to balance of macrocosm (temperature falls or rise, Selametan (thanksgiving) etc.) Artifacts: results of spatial planning knowledge; axis, Hear: indicators of Sultan Ground-Wedi Kengser, temples & rivers, pranatamangsa (sound of cats in mating season, baby

resource management: ancient water network, Mataram channel birds hatching, etc.)

Resource management practices: Taste: - Wangsit on 700 years eruption cycle, geger bulus, Smell: - lahar occurrences

Pranata mangsa (Javanese seasonal calendar) symbolization Worldview: Philosophies of Manunggaling kawula Gusti (unity of people with their King ) Sangkan paraning dumadhi (remember the origin layers of forms of and purpose of life) Hamemayu hayuning bawono (beautifying the knowledge beauty of the world ) legitimatization Merapi is my ancestor symbolization Values: relates to the philosophies; obeying the ruler, do good to humanities and environment, fatalism attitude towards Merapi CEK Patterns in Argomulyo

Nature dynamics: flood, lahar Labuhan and Merti Taste: -

Artifacts: context of spatial planning in VRB: Smell: - Tugu as the starting of imaginary axis and floodplains: Sultan Ground-Wedi Kengser

Resources management: no longer believe in symbolization pranata mangsa, water quality degradation, lahar as sand sources, cycle of flood and lahar management

Worldview: the philosophy of Hamemayu hayuning bawono layers of forms of Values: almost forgotten, but some are still exist in the case of disaster and cultural knowledge events, relates to the hamemayu philosophy: gotong royong, volunteerism. legitimatization symbolization CEK Patterns in Kebonagung

Historical experiences: legitimatization Mechanism of transfer: 5 Senses Wisdom Knowledge generation: by leading Visual: person & elders Institutionalized structure: Soil fertility indicators Merapi Ash as fertilizer Response: the use of lahar sediments as Structure in tourism communities (desa wisata) & pranata mangsa indicators (broken agricultural land, volcanic ash as agriculture group (poktan) land, cat mating season, etc.) fertilizer Institutionalized dynamics: tourism and agriculture Conservation: the river community activities Touch: pranata mangsa indicators Temporal experiences: season Internalization: relates to downstream context and history of Kraton Hear: pranata mangsa indicators Nature dynamics: flood, lahar Myth-Artifact: and the Lumpang: the (cat mating season, etc.) sedimentation stone mortar from ancient Javanese civilization, relates to the Taste: - Rituals: Wiwitan Smell: - Nini Thowong Performances Artifacts: results of river’s dynamics and human

Historical experiences: natural dynamics, response, conservation, temporal experiences

Philoso phiesCEK & values

Ever symbolization process Legitimatization process corridor Types of mechanism of transfer Conclusions . The process of CEK formulations: historical experiences legitimatization forms of knowledge in ever-symbolizations . The CEK is still in use (partially or holistically) . Potential contributions of CEK in volcanic river basin management: . transfer of knowledge or communication strategy, . water and lahar related disaster strategy, . water-lahar resources management practices with contextualization of modern scientific approaches Outlook • Based on these results, there are traces of nexus approach as interrelations between water, volcano, and lahar resources management using CEK • As the next stage, further development of interrelations between the management of these resources will be dealt using the nexus approach. • This approach will be used to answer the next sub-RQs: “What are the current policies for managing integrated water resources management in a volcanic river basin?” and ”What are the relations of lahar risks management (LRM) in integrated water resources management?” References
