In parallel with these efforts, Perlas pioneered the introduction of large scale commercial organic and biodynamic agriculture in many provinces in the Philippines. All these efforts were the fruition of early advocacies in sustainable agriculture when he was still an agricultural journalist and columnist at the Modern Agriculture and Industry-Asia, where he pioneered the first monthly articles on ecological agriculture in the Asian context. Together with colleagues at the International Alliance for Sustainable Agriculture or IASA, he coined the term sustainable agriculture in 1983, a term which has received wide use and currency until today.
