Conceptual Framework Towards Adaptive Resilient System
COMPREHENSIVE RESILIENCY PLAN:
Ecosystem-Based Approach
Critical Resource Resiliency Planning
Identify vulnerable resource input; restore ecosystem/natural
defences; monitor ecosystems
Disaster Risk Management
Identify Emergency Response, early warning, preparedness
and preventive measures
Climate Change Adaptation
Identify adaptation Options: engineering measures and
natural solutions
Critical Infrastructure
Resiliency PlanningIdentify and reduce business
vulnerability
CLIMATE CHANGE & NATURAL HAZARDS
Critical Infrastructure Resiliency Planning
Vulnerability Assessment of Project Facilities
Comprehensive Resiliency Management Plan for BacMan Geothermal
Facilities
Critical Infrastructure Resiliency programs have been identified.
Vulnerable Facilities of Bacman Geothermal Project has been identified and mapped-out.
Critical Infrastructure Resiliency Planning
OBJECTIVESDetermine and Identify the level of vulnerability
of EDC’s critical infrastructures including
its immediate environment to climate and change and major hazard and its effects;
Assess existing coping mechanisms (if any) to climate change hazards
and propose appropriate strategies for adaptation and/or mitigation of the
hazards; and
Enhance EDC’s technical knowledge to better
understand and make use of climate information, and enhance relevant
data and access to data for planning and decision-
making.

Plan for SustainabilityProjects should be designed so their impact continues long after the company’s involvement. Projects that focus on developing community skills and capacity or improving community incomes yield more sustainable benefits than projects and programs that simply distribute goods and services. Companies can plan for sustainability with communities by building community capacity to manage projects and encouraging links with other organizations. Companies should prepare to hand over responsibility for projects to communities, governments or other organizations once the program has become sustainable and self-sufficient. Setting a timetable to hand over responsibility with measurable goals and benchmarks is essential to avoiding dependency.
