个人简介
Uphoff is a subject-matter expert in development administration, irrigation management, local participation, and strategies for broad-based rural development. His interests have expanded beyond the social sciences to include new knowledge and practice in soil science and microbiology. In 1993, he became acquainted in Madagascar with the System of Rice Intensification (SRI) through the NGO Association Tefy Saina. Farmers who used SRI methods, having gotten paddy yields averaging only 2 tons/hectare paddy with their usual methods, on soil that was evaluated as 'very poor,' without using new varieties and without depending on chemical fertilizer, and with less water, were able to average 8 tons/hectare. After such results were attained for three consecutive years and were seen in other parts of Madagascar as well, Uphoff began trying to get agricultural specialists in other countries to use and evaluate the alternative SRI methods for themselves. In 1999–2000, SRI results were validated by rice scientists in China and Indonesia, and since then, the testing and dissemination of SRI have spread to almost 50 countries, showing how more rice can be produced with less water, less cost, and often less labor. But this agroecological methodology has not been without its critics and opponents
