The provision of water supply and sanitation services is particularly vulnerable to projected changes in climate conditions (temperature and precipitation among others), in the frequency and intensity of extreme weather events, as well as and in the projected rise in sea-level and the intensification of storm surges. The process of climate proofing investment projects aims both at assessing the climate risk to a project's future costs and benefits, and undertaking a technical and economic analysis of options to alleviate or mitigate those risks. Accounting for climate change at the outset of the project cycle implies that decisions about project design, and the adoption and timing of climate-proofing measures be informed with the possible impacts of climate change in the initial phases of the project cycle so that decisions of an irreversible nature will be avoided. This publication presents a step-by-step methodological approach to assist project teams in managing climate change risk in the context of water supply and sanitation investment projects.

This publication provides a step-by-step methodological approach to help project teams assess and incorporate climate change adaptation measures into energy investment projects. While the focus of the guidelines is at the project level, an improved understanding of climate change impacts should also be used to incorporate climate change considerations into energy planning and policy at the country level.

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.

This publication aims to present a step-by-step methodological approach to assist project teams to incorporate climate change adaptation measures into transport sector investment projects. While the focus of the publication is on the project level, an improved understanding of climate change impacts should also be used in the design of infrastructure planning and development policies and strategies to ensure appropriate resource allocation. Though the transport sector includes roads, waterways, rails, and airborne transport, this publication focuses solely on road infrastructure.

The Climate Change Operational Framework 2017-2030 is intended to provide broad direction and guidance for enhancing resilience and strengthening climate actions in the operations and business processes of the Asian Development Bank (ADB). It positions ADB to facilitate, collaboratively and proactively, a regional shift toward a low greenhouse gas emissions and climate-resilient development path. The operational framework provides guidance across all ADB sector and thematic groups to support climate adaptation and mitigation actions, operationalizing ADB's commitment to provide at least $6 billion per year in climate change financing from its own resources by 2020. It outlines actions and the institutional measures to be implemented to enable ADB to meet the climate needs of its developing members.

This publication aims to present a step-by-step methodological approach to assist project teams assess and incorporate climate change adaptation measures into investment projects in agriculture, rural development, and food security. While the focus of the publication is at the project level, an improved understanding of climate change impacts should also be used to incorporate climate change considerations into agriculture planning and policy at the country level. Though rural development projects include irrigation, rural infrastructure, agriculture production, and natural resource management, this report focuses mainly on irrigation infrastructure projects and agriculture production projects.

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 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.

Today's climate variability already has a large impact on water supply and protection. Millions of people are affected every year by droughts and floods. Future climate change is likely to make things worse. Many people within the water sector are aware that climate change is expected to have serious consequences for water resource management, but they are unsure how to incorporate climate information into their management structures. Providing a compendium of specific strategies, Climate Change Adaptation in the Water Sector is the first book to show students and professionals in the water sector how to adapt to climate change and variability. It enables advanced students, managers, decision-makers and other practitioners to feel comfortable in analysing and using climate data within the water sector. The book consists of two parts: the first describes the general issues and is written mainly by the editors of the book, while the second part contains specific case studies drawn from a wide range of contrasting countries: Australia, Germany, The Netherlands, the Philippines, South Africa, Thailand and Yemen.

WATER, CLIMATE CHANGE, AND SUSTAINABILITY An in-depth review of sustainable concepts in water resources management under climate change Climate change continues to intensify existing pressures in water resources management, such as rapid population growth, land use changes, pollution, damming of rivers, and many others. Securing a reliable water supply—critical for achieving Sustainable Development Goals (SDGs)—requires understanding of the relation between finite water resources, climate variability/change, and various elements of sustainability. Water, Climate Change, and Sustainability is a timely and in-depth examination of the concept of sustainability as it relates to water resources management in the context of climate change risks. Featuring contributions by global authors, this edited volume is organized into three sections: Sustainability Concepts; Sustainability Approaches, Tools, and Techniques; and Sustainability in Practice. Detailed chapters describe the linkage between water and sustainable development, highlight the development and use of new measuring and reporting methods, and discuss the implementation of sustainability concepts in various water use sectors. Topics include localizing and mainstreaming global water sustainability initiatives, resilient water infrastructure for poverty reduction, urban water security for sustainable cities, climate actions and challenges for sustainable ecosystem services, and more.
