Indonesia’s rice farmers test climate-friendly methods that cut methane emissions, raise yields

In the heart of Indonesia's Central Java province, a quiet revolution is taking root in the paddy fields. Farmers, traditionally bound by age-old methods, are embracing a new approach to rice cultivation that promises not only to boost their harvests but also to significantly mitigate the environmental impact of this vital crop. This initiative, spearheaded by Singapore's Temasek Life Sciences Laboratory as part of its Decarbonising Rice Project, represents a crucial step towards sustainable agriculture in a region heavily reliant on rice production.

Most of them are quite traditional. They were worried that such projects might not succeed or could lead to crop failure. But after we explained the methods and how everything would be done, the farmers gradually accepted it.

Central Java, a powerhouse contributing over 16% to Indonesia's national rice output, is the perfect testing ground for these innovative techniques. The project integrates modified irrigation practices, a specially formulated fertilizer mix, and climate-resilient rice varieties. This holistic approach tackles the issue of methane emissions, a potent greenhouse gas released from flooded paddy fields, which accounts for a substantial portion of global agricultural emissions. The initial results are highly encouraging, with trials indicating a potential reduction in methane emissions by as much as 50%.

For farmers like Kasno, a 55-year-old participant from the Grobogan regency, the transition was not without its initial skepticism. "Most of them are quite traditional," he admits, referring to his fellow farmers. "They were worried that such projects might not succeed or could lead to crop failure." However, the project's meticulous explanation of the methods and the tangible benefits have gradually won them over. Kasno himself has seen his yields climb from six to seven tonnes per hectare to an impressive eight to nine tonnes, translating into a remarkable 30% increase in his profits. This tangible economic incentive is a powerful driver for adoption, demonstrating that environmental responsibility and financial gain can go hand in hand.

The results were positive and we could increase the yield of the farmers by 6 per cent even though it was flooding.

The success of this project in Indonesia, mirrored by similar trials in India and Laos, underscores the regional and global significance of developing climate-friendly agricultural practices. While Western media might focus on the technological or scientific breakthroughs, for Indonesian farmers, this is about securing their livelihoods, improving their economic standing, and contributing to a healthier planet. The project's success is a testament to the adaptability and forward-thinking spirit of Indonesian farmers, who are not just cultivating rice but also sowing the seeds of a more sustainable future for agriculture.

Globally, flooded rice fields account for about 12 per cent of methane emissions, releasing around 60 million tonnes each year.
