The Asia and Pacific region is vulnerable to extreme temperatures, flooding by heavy rainfall, sea level rise, coastal erosion, and damage by tropical cyclones. This technical note provides information that supports climate risk assessment experts undertaking early stages of project development in the region. The information is grouped into four major categories: inventories of national emissions, climate risks, vulnerability, and impacts; historic weather, climate, and environmental change; regional climate change projections; and climate change impacts and adaptation. The note also identifies opportunities for capacity development in key skills such as geospatial analysis, data testing and post-processing, regional climate downscaling, and impact assessment.

This guidance provides a tool governments and development co-operation can draw on in their efforts to strengthen the resilience of human and natural systems to the impacts of climate change. It highlights three aspirations to consider when planning and implementing action to build climate resilience (country ownership; inclusiveness; and environmental and social sustainability).

This publication presents findings from a climate change risk and adaptation assessment in southern Viet Nam as part of the Water Efficiency Improvement in Drought-Affected Provinces (WEIDAP) project supported by the Asian Development Bank. It highlights new developments and key lessons on climate risk assessment that may be applied to the project design and monitoring as well as the implementation of climate adaptation measures. The WEIDAP project was developed in response to the drought that affected southern Viet Nam in 2015–2016. It focused on irrigation modernization and the integration of climate-resilient agricultural and efficient on-farm water management practices.

Nature-based solutions (NBS) are interventions to protect, restore, and sustainably manage natural or modified ecosystems to support both biodiversity and human well-being. This guide explores the benefits of using NBS in a suite of development options to promote sustainable and resource-efficient infrastructure. It includes case studies from Bangladesh, Nepal, the People's Republic of China, the Philippines, and Viet Nam to show how NBS can be mainstreamed in the portfolio of the Asian Development Bank.

This step-by-step manual describes procedures for climate change adjustments relative to extreme rainfall and local sea level estimates. The principles presented are based on worked examples discussed in the knowledge product accompanied by this manual. While the overall approach on climate change adjustment procedures and calculations are intended to be as transparent as possible, key sources of information and assumptions are open to scrutiny as some elements may be affected by rapid advancements in science and technology. It is essential for data to be periodically reviewed, in line with the latest reports from the Intergovernmental Panel on Climate Change.

Climate change represents an increasing threat to the continued development of the people, preservation of ecosystems, and economic growth of Asia and the Pacific. Mainstreaming climate risk management in all aspects of development is thus key to an effective transition to climate-resilient development pathways. ADB's climate risk management framework aims to reduce risks resulting from climate change to investment projects in Asia and the Pacific. A key step in this framework is the technical and economic valuation of climate-proofing measures. This report describes the conduct of the cost-benefit analysis of climate proofing investment projects. An important message is that the presence of uncertainty about climate change does not invalidate the conduct of the economic analysis of investment projects, nor does it require a new type of economic analysis. However, the presence of uncertainty does require a different type of decision-making process in which technical and economic expertise combine to present decision makers with the best possible information on the economic efficiency of alternative designs of investment projects.

Disasters damage and destroy infrastructure and disrupt economic activities and services, potentially delaying long-term development and hampering efforts to reduce poverty in the region. Countries require a strong enabling environment for disaster risk financing to ensure the timely availability of post-disaster funding. This report presents a comprehensive diagnostics tool kit that countries can apply to assess the financial management of disaster risk. The framework examines the state of the enabling environment and provides a basis to enhance financial resilience with insurance and other risk transfer instruments. It incorporates lessons from the country diagnostics assessments for Fiji, Nepal, Pakistan, and Sri Lanka that made use of the tool kit and methodology.
