Founded in 1989, the Nagao Natural Environment Foundation (NEF) is a non-governmental organisation dedicated to promoting nature conservation in developing countries. Since its establishment, the Research Grant Scheme has supported researchers from research institutions mainly in the Asia-Pacific region. A total of 424 research projects in 25 countries have been awarded grants during this period (as of 30 April 2016). Meanwhile, the Scholarship Scheme has given support to a total of 5,086 students in nine countries in Asia (as of 30 April 2016).
In September 2007, the NEF reviewed its schemes in order to contribute to nature conservation more effectively. In addition to the original Research Grant and Scholarship Schemes, they extended their support to include the intensive production of scientific work and filed activities under a new scheme called the 'Comprehensive Programme for Conservation Research and Activities.'
