A previous study commissioned by the League of Cities of the Philippines and funded by the United Nations Environment Programme showed that Sorsogon, an emerging city in the Philippines, does not possess enough data to enact sound policies that balance economic growth and environmental sustainability. To help the city make quality policy decisions, the author designed a knowledge management framework that city leaders can use. The said framework was based on the classic works of Nonaka and Takeuchi (1995) and Davenport and Prusak (1998), as well as publications of the Asian Productivity Organization on knowledge management in the public sector. The author also provided examples of specific strategies that Sorsogon City can use to operationalize the framework.
