A. Purpose and Objectives:

ADPC is an autonomous international organization established for scientific, educational, developmental, and humanitarian purposes with a vision of safer communities and sustainable development through disaster risk reduction and climate resilience in Asia and the Pacific. Established in 1986 as a technical capacity building center, ADPC has grown and expanded its role to be for scientific, educational, developmental and humanitarian purposes. ADPC employs a wide range of professional expertise typically required for Disaster Risk Reduction (DRR) and Climate Resilience (CR) in an effective manner.

ADPC develops and implements cross-sectoral projects/programs on the strategic themes of risk governance, urban resilience, climate resilience, health risk management, preparedness for response and resilient recovery. Our strategic themes are complemented and underpinned by the cross-cutting themes of gender and diversity, regional and transboundary cooperation as well as poverty and livelihoods.

Through its work, ADPC supports the implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030, the Sustainable Development Goals (SDGs), the New Urban Agenda, the United Nations Framework Convention on Climate Change, the agenda defined at the World Humanitarian Summit in 2016, and other relevant international frameworks.

B. Department Introduction

The Risk Analytics and Climate Services Department is a multi-disciplinary team of experts committed to providing innovative, science-based solutions for actions to adapt to climate change and mitigate the impacts of disasters. The innovations include uses of geospatial technology, satellite data, numerical models, cloud computing, and artificial intelligence for assessing vulnerability and risk, generating climate data, developing early warning systems, forecasting possible climate impact, and informing anticipatory actions. These lead to risk-informed developments in the sectors such as agriculture, transportation, water resources, energy, communications and health.

The department also applies advanced geoinformatics and climate analytics to address water and food security issues by assessing water availability and water-use efficiency, groundwater monitoring, assessing drought risks, and optimizing agricultural productivity, hence ensuring sustainable water and food systems in vulnerable regions. The department promotes Nature-Based Solutions by leveraging ecosystem services such as wetland restoration, agroforestry, and green-gray infrastructure to reduce disaster risks and build climate resilience. Lastly, the department produces risk analytics and integrates them into urban plans and engineering designs of critical infrastructures, hence improving their resilience to disasters and climate change.

With a commitment to science-based approach, the department envisions empowering stakeholders to reduce risks, adapt to climate change, and build more resilient communities and ecosystems.

C. Statement of Intent

Asian Disaster Preparedness Center, in collaboration with International Union for Conservation of Nature and Natural Resources (IUCN), is implementing a six years project named “URBAN: Urban Resilience Building and Nature” in two provinces of Thailand (Chiang Rai and Surat Thani). The overall goal of the project is that the focal urban areas and wider landscapes in which they are embedded enjoy significantly enhanced social, economic and environmental resilience to climate change impacts through the wide scale adoption of nature-based solutions NbS. The project will make a significant contribution to climate change adaptation in up to 6 local administrative organizations in the selected provinces in Thailand.

As part of the project implementation, ADPC intends to hire a consultant on a lump-sum output-based contract to prepare flood hazard maps for select urban areas in the targeted provinces of Chiang Rai and Surat Thani considering future climate change impacts including increasing flood risks and sea-level rise where applicable.

D. Scope of Work
