The Spirit of Giving »

The holiday season in the Philippines is always cause for many celebrations, videoke, and pancit (noodles). At the Yason Family Farm School, it is no different. Once all the students finished their final exams, the school participated in a local Christmas parade in San Mariano, and Family Day, in which each grade level held a classroom party. While some traditional gifts are given - clothes, baked goods, household items - this year, three families also received d.light S20 solar lights thanks to generous donations raised by former Kopernik fellow and volunteer Emily McQualter.

Gauging and engaging with Myanmar »

Myanmar. Burma. The former rice basket of Asia. After decades of political isolation, Myanmar opened its doors to the outside world in 2011, opening up new economic opportunities that investors, donors and nonprofit organisations are keen to explore. Kopernik has been investigating the demand for simple, life-changing technologies that will benefit the many people living in poverty. After a productive trip this month, we are a step closer to making this happen.
