On May 13, 2015, Prof. Jonna P. ESTUDILLO, from National Graduate Insitute For Policy Studies, provided us a seminar about economic development, Green Revolution, and food security in the Philippines. Detailed data, heart-touching videos and comprehensive explanation enhanced our understanding of the relevant issues in the Philippines. The information about Coron is very helpful for our participants to understand the general situation of the field where we are going to visit in September. In the end of the seminars, students actively joined the discussion and exchanged information together.
