89. Lesson 7. There are more good theories on climate change response than facts. Developing an effective, viable and efficient response to climate change on a national scale has never been done…anywhere, by anyone. For a country of the size and complexity of Viet Nam, to have made the commitment to accomplish just this is highly laudable. The approach being taken − incremental, to be carried out over the next forty years − is sensible and pragmatic in that it takes a (mostly) one-step-at-a-time approach, accompanied by continued research and information gathering. It will be an empirical process and, like as such processes, will be one of trial-and-error. As such, the 2011-2015 period of the MARD Action Plan should be understood as a period of learning. And, as a period of learning, there should be very intentional, very systematic and structured processes and activities built in so as to ensure that learning is captured, shared and fedback into the policy, strategy and decision-making dialogue and process.
