In this section, the perspectives of local wisdom are characterized and exemplified clearly within two different countries, the Philippines and Indonesia. Through observation of the situation in Calamba City, Laguna—the Philippines, the discussion examines the validity of indigenous knowledge (IK), questions the present-day application of local wisdom to tropical ecosystem problems in academic research, and suggests the need to investigate the dynamism, interaction, and transformation of knowledge beyond the framework of local areas in order to better understand local realities and build a broader network of cooperation. Later, the subsequent discussion explores the potential of the local wisdom in freshwater management of several urban areas in Indonesia.
