The global food system is responsible for between 20-30% of greenhouse gas emissions. How can we produce rice, a food staple eaten by over half the world’s population — in a way that uses fewer resources and regenerates nature? More and more farmers around the world are adopting an agroecological approach called the System of Rice Intensification (SRI), which reduces water use, methane production, and the use of chemicals, while providing better yields and reducing labour for rice farmers.

Water is vital to our existence. It is no doubt that we need water to live, and it is expected that demand for water will only increase as our population grows. But can we meet this demand while ensuring that we reach our carbon emission targets in the future? The water sector contributes to about 2% of greenhouse gas emissions, and while this is not significantly large, it is still a meaningful amount.

AECOM’s Scott Dunn, Chief Strategy Officer, Asia, and Beverley Stinson, Chief Executive, Global Business Line ‒ Water, join this discussion at the Singapore International Water Week 2022. They explore innovative and smart solutions on how we can potentially reduce carbon emissions in the water sector for a future with more water and less carbon.

The global food system is responsible for between 20-30% of greenhouse gas emissions, most of which are generated at the production stage. Take rice, for example, a food staple that is eaten regularly by over half the world’s population.
Conventional rice production generates emissions equivalent to the entire global aviation industry. So how can we produce rice in a way that uses fewer resources and regenerates nature? A growing number of farmers around the world are changing the way they produce rice, by adopting an agroecological approach called the System of Rice Intensification (SRI).
This method relies on a small group of simple interventions that together significantly reduces water use, methane production, and the use of chemicals, while providing better yields and reducing labour for rice farmers.
Multinational companies who support this type of agriculture through procurement and product design can address their scope 3 emissions and build resilience in their supplier communities.
According to Project Drawdown, SRI currently accounts for 4% of rice production. If this was increased to 25%, the emissions reduction would be equivalent to that which is currently generated by the whole of India.

Ecology on Khan Academy: Why are polar bears found only in the Arctic? Why does mildew grow in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environment, and how these interactions affect where, and in what numbers, different types of organisms are found.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
