1) Indonesia is the world's largest palm oil producer, with over 8 million hectares of plantations, most located in Riau Province. Palm oil farming relies heavily on chemical fertilizers which can harm the environment long-term. 2) Introducing livestock grazing under palm trees and using their waste as organic fertilizer is one solution for more sustainable palm oil production while reducing costs. 3) A project in Riau introduced livestock farming technologies to 30 farmers, including producing liquid organic fertilizer from cattle waste and using palm byproducts for feed. After 2 years, 19 farmers adopted the technologies, reducing fertilizer costs by 50-60% and doubling their cattle herd.
