Development ofOnline Synthesis System (OSS)
Background

Disaster resilience and sustainable development are closely interlinked.

Proper disaster management and capacity development must lead to the city/region's continuousprosperity.

Objectives


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

To foster facilitators capable of leading the accumulation of dialogues and communications toimprove 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.

Candidates of facilitator
Candidates for the facilitator should be invited from different disciplines and sectors ofsociety 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 scienceincluding 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 beorganized. Also, collaborative works with ongoing programs/activities in Davao City,
such as Local Climate Change Adaptation Plan by TWG, SETI projects, DRRM forUrban Water System, NICER, and Master Plan of the Davao River, should beexamined.

 As the next stage, a policy proposal including land use planning, economic growthstrategy, and water security under climate change impacts should be co-designedwith stakeholders beyond the disaster response. Activities for disaster resilience andsustainable development under climate change have to contribute to thecomprehensive and continuous prosperity of Davao City.
 To create a sub-committee under DRBMA for the sustainable operation of OSS
