It is likely to exacerbate the frequency and intensity of extreme weather events. The region contains seven out of the world’s ten most vulnerable countries and the economic impacts could be huge. Asian Development Bank (ADB) studies forecast that under a business-as-usual scenario, annual economic losses could be as high as 5.3% in East Asia or as much as 12.7% in the Pacific by 2100. On the average, economic costs of disasters in Asia and the Pacific region could reach $53.8 billion annually. In 2013, developing Asia accounted for 35% of energy-related global carbon dioxide emissions and continues to rise, further aggravating the region’s vulnerability. Against this background, ADB is strengthening its commitment to assisting its developing member countries (DMCs) in meeting the climate change challenge. In its recent Midterm Review of Strategy 2020, which guides all of ADB’s work, climate change was identified as one of ten strategic priorities. As such, ADB is, inter alia, enhancing its focus on climate change adaptation, mainstreaming resilience and integrating adaptation and disaster risk reduction measures into all its activities, including operations and country policies. ADB has already mandated climate risk management in all its projects. Last year, ADB provided $3.27 billion for climate finance, $988 million of which was for adaptation initiatives. Although finance is imperative in addressing climate change effectively, technological solutions will also play a key role. Acknowledging the importance of technology, ADB’s Regional and Sustainable Development Department, under the technical assistance on Enhancing Knowledge on Climate Technology and Financing Mechanism funded by the Government of Japan, has compiled this compendium to help DMCs identify technologies that would help them address the impacts of climate change. The available and innovative technologies that are detailed here address the climate change impacts in six sectors: agriculture, coastal resources, human health, transportation, water resources, and disaster risk management. The document includes information on the effectiveness, cost, benefits, and barriers abouteach technology. Disseminating this very timely information is the first step in recognizing that technologies are already available today to promote green growth and, more importantly, to enable adaptation to a changing climate. Sound and sustainable technological choices enhance resilience and facilitate adaptive behavior and development. I hope this document will provide a useful reference for ADB’s DMCs. Ma. Carmela D.
