Rice sector must cut methane emissions

International cooperation is urgently needed to reduce greenhouse gas footprint of rice production, says Olam co-founder and Group CEO, Sunny Verghese.  

The agri-sector along with brands, retailers, financial institutions, scientists and governments must implement solutions to limit methane emissions from rice production, while improving farmer livelihoods and food security. This has to take into account that many rice consumers are unable to pay more, according to Olam.

At the 5th International Rice Congress (Singapore 15-17 October 2018), Sunny Verghese, co-founder and Group CEO of Olam, one of the world’s largest rice traders, is expected to call on stakeholders to advance the implementation of the Sustainable Rice Platform (SRP) Standard. This is especially important in Southeast Asia, which depends enormously in rice production. SRP promotes climate-smart practices. To achieve real scale, financial market support, reduced tariffs and freeing up capital by promoting the benefits of sustainable rice to more affluent consumers, are required.

“Rice production emits the same level of CO2 equivalent as Germany through methane emissions1. But climate change mitigation cannot be a trade-off that hurts the farmers and communities who depend on rice for income and sustenance. This is especially so when rice is the largest staple crop in the world, feeding half of humanity. We must re-imagine the whole supply chain if the world is to become carbon neutral by 20502,” Mr. Verghese said.

Global Head of Rice at Olam, Devashish Chaubey, said, “Our programmes with the Thai Rice Department, development agency GIZ3 and others prove that the SRP Standard works4. Together, we are aiming to reach 150,000 farmers by 2023 in Asia and Africa. Yet, this represents a mere 0.1% of total global rice farming households. Greater scale requires more impactful action by the whole of the rice sector.”

Rice production is a leading cause of climate change, emitting the same level of CO2 equivalent as Germany through methane emissions.

Southeast Asia staple

Rice is one of Southeast Asia’s biggest crops and the financial backbone for millions of farmers across the region5. As highlighted by the recent IPCC global warming report, the yields and nutritional value of rice face net reductions should temperatures rise.

Consequently, this will impact millions of farmers and families, particularly those on low incomes.

Yet rice is also a leading cause of climate change. Methane, a greenhouse gas (GHG) which is up to 34 times more potent than carbon dioxide6, is emitted as a result of rotting vegetation in the water-soaked paddy fields, also impacting on water security7. Climate-smart agri-practices such as the removal of rice straw can reduce methane emissions by 70%8 but farmers need training and support from the market.

Who can help and how?

Brands and retailers: Commit to promoting and selling sustainable rice

Developed countries consume 23 million metric tonnes (MMT) of rice every year9. Major brands and retailers can catalyse change by choosing the SRP as a procurement standard and promoting awareness of better rice production systems to consumers. Developed by multiple parties, SRP is a simple ‘plug and play’ approach. 

Financial institutions: Reduce interest cost for sustainable rice farmers

More resilient production systems from sustainable projects would reduce variance in production – and thereby prices – and offset risk. Financial institutions should reflect this in lower interest rates for farmers who commit to sustainable rice production. A 0.25% reduction in interest rates can potentially translate to US$500 million in cost savings10 per year for participants higher up in the rice supply chain, which could in turn be passed down to farmers to incentivise the switch to SRP rice.

Insurers: Reduce premiums for more resilient sustainable rice producers

The lack of risk management tools in the market is a hindrance for farmers’ income and disruptive to long-term engagement. Improving insurance offerings are a necessary first step to better credit offerings at farm-level.

Agronomists and scientists: Focus on field-level improvements to improve resiliency and clarify GHG reduction methods

Despite a great deal of work, there are emerging new findings suggesting that the methane problem is compounded by nitrous oxide releases (298 times more potent than carbon dioxide11) and outdated farm practices. Understanding the practical solutions that can be delivered to the farmers quickly and providing better tools to measure the GHG impacts of these choices is imperative.

Governments: Reduce tariffs and taxes for sustainable rice

The 2017 global tariff for rice (weighted by volume) is 32%. A 1% reduction in tariffs for sustainable rice would be worth more than US$150 million per annum in savings for exporters12, which could in turn be passed down to farmers to incentivise the switch to SRP rice.

Director at GIZ, Dr. Matthias Bickel, said, “The Thai Rice NAMA project13 will support 100,000 rice farming households in Thailand to shift from conventional to low-emission rice farming, reducing emissions of irrigated rice by 29%. Translating these climate benefits into economic incentives for farmers is done by applying the ‘Sustainable Rice Platform Standard’. Treating small-scale rice farmers as ‘agripreneurs’ and incentivising them to invest in their farms will make the difference.”  - SOURCE: OLAM
