Emerging markets and low-income countries continue to need large investments in infrastructure to remove constraints on growth; create job opportunities; respond to urbanization pressures; and meet crucial development, inclusion, and environmental goals. In 2009, ADB estimated that an infrastructure investment of $8 trillion would be required during 2010–2020 to maintain current levels of growth in Asia.

Infrastructure for transport and communications, energy generation and transmission, and the supply of water and sanitation are critical for development. These types of infrastructure usually have long service lives, which renders both the region’s existing infrastructure stocks and its future infrastructure investments vulnerable to changes in climate conditions that may take place in the near and medium terms. One of five overarching reasons for concern cited by the fifth assessment report of the Intergovernmental Panel on Climate Change in 2014 was the existence of systemic risks “due to extreme weather events leading to breakdown of infrastructure networks and critical services such as electricity, water supply, and health and emergency services.”

The Technical Assistance study focusses on “building climate change resilience in Asia’s critical infrastructure”. The expected impact of the study is scaled-up support for effective climate change adaptation. The expected outcome of will be an enhanced knowledge base on climate change risks to critical infrastructure in South Asia and Southeast Asia. Specifically, by the end of the study it is expected that Asian Development Bank (ADB) and its Development Member Countries (DMC) will have a fuller understanding of the actions and innovation needed to make critical infrastructure in South Asia and Southeast Asia more resilient to climate change.

The study will focus on 11 countries in South and South-East Asia with three countries in specific: Indonesia, Sri Lanka and Vietnam.
