Increase in rainfall Steep slopes unstable soil conditions; Settlements and crop lands in flood prone and landslide prone areas; Terrestrial wildlife habitats 3. Drought Grasslands, shrublands and forests; crop lands Groundwater recharge areas, rivers Terrestrial wildlife habitats 4. Increase in ambient temperature Terrestrial and aquatic habitats Urban settlements 5.

. Disaster resilience and sustainable development are closely interlinked.

. Proper disaster management and capacity development must lead to the city/region's continuous prosperity. Objectives

. To develop an Online Synthesis System (OSS), achieving prevention and mitigation efforts of water- related disasters by synthesizing data, knowledge, information, experience, know-how, and technology for relevant stakeholders such as city office, regional/local governmental agencies, academia, and Barangay leaders.

. To foster facilitators capable of leading the accumulation of dialogues and communications to improve disaster resilience and sustainable development by the effective use of OSS.

. To disseminate the climate change initiatives in Davao City to the world as one of the best practices.

13 Candidates of facilitator

Candidates for the facilitator should be invited from different disciplines and sectors of society including civil society. Criteria for gathering candidates are as follows.

. CRITERIA 1 (Direct disciplines): Those who have a background in DRRM, CCA, Sustainability, IWRM, RBO management, Flood management, and Climate/meteorology

. CRITERIA 2 (Good mix of sciences): Natural science, Engineering, Social science including communication, ICT, and Communicator in the mother tongue.

. CRITERIA 3 (Representation from different levels of governance): Barangay, City/ Municipality, National government, Private sector/Industry, Civil society, Academe, Media, and Special representation from DRBMA which is an interregional body.

. CRITERIA 4: Members of HELP Davao Network

14 Further vision

. For the implementation of OSS and capacity development programs, online workshops gathering all relevant Davao City stakeholders are suggested to be organized. Also, collaborative works with ongoing programs/activities in Davao City, such as Local Climate Change Adaptation Plan by TWG, SETI projects, DRRM for Urban Water System, NICER, and Master Plan of the Davao River, should be examined.

. As the next stage, a policy proposal including land use planning, economic growth strategy, and water security under climate change impacts should be co-designed with stakeholders beyond the disaster response. Activities for disaster resilience and sustainable development under climate change have to contribute to the comprehensive and continuous prosperity of Davao City.

. To create a sub-committee under DRBMA for the sustainable operation of OSS
