Up in smoke? Asia and the Pacific The threat from climate change to human development and the environment Foreword by R K Pachauri, Ph.D, Chairman of the Intergovernmental Panel on Climate Change The fifth report from the Working Group on Climate Change and Development The human drama of climate change will largely be played out in Asia, where over 60 per cent of the world’s population, around four billion people, live. The latest global scientific consensus from the Intergovernmental Panel on Climate Change (IPCC) indicates that all of Asia is very likely to warm during this century. Warming will be accompanied by less predictable and more extreme patterns of rainfall. Tropical cyclones are projected to increase in magnitude and frequency, while monsoons, around which farming systems are designed, are expected to become more temperamental in their strength and time of onset. This report asks, will global warming send Asia and the Pacific ‘up in smoke’?

I am glad that the current volume continues in the same spirit and direction that was evident in the first. It is becoming increasingly clear that development policies and initiatives will have to include explicitly several aspects related to climate change. While going through the foreword that I wrote for the 2004 volume, I find that the concerns and priorities that I had touched on as part of that write-up, if anything, have become stronger, and the uncertainties associated with what I had stated then have been reduced significantly. Since 2004, we have recently brought out three reports of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report which deal with the physical- science basis of climate change; aspects of impacts, vulnerability and adaptation, as well as mitigation issues. One dominant characteristic of these reports is the significant advance that has taken place in knowledge related to climate change based on recent research that has been carried out in several parts of the globe. Unfortunately, there are still gaps which exist in several countries and regions, which require to be filled up urgently through location-specific research if we are to come up with meaningful plans and priorities for action. The reports of the IPCC Working Groups, which have been completed and released this year, shed new light on observations related to climate change in several parts of Asia as well as on projects for the future. It has become clear that Asia would see some major changes as a result of the impacts of climate change, and several of these are becoming evident already. Even more compelling are the projections of future climate change and associated impacts in Asia, which require an integration of adaptation to climate change with development policies. Required measures would include improvements in the efficiency of water use, upgrading healthcare and medical services, proper formulation and implementation of coastal zoning regulations as well as changes in agriculture, which may be affected by reduced yields of some crops. It is hoped that this volume will be read carefully by policy-makers, researchers, industry executives and members of civil society in Asia and elsewhere, to gain insights into the challenge of climate change in this region and the steps required to tackle it.
