Gates Funds Climate-Smart Rice Development
By Sunny Lewis
LOS BANOS, Philippines, January 6, 2015 (Maximpact.com News) – Climate change-ready rice seeds of several varieties have reached millions of farmers in Asia and Africa under a forward-looking program known as Stress-Tolerant Rice for Africa and South Asia, or STRASA.
Developed by the Los Baños-based International Rice Research Institute (IRRI) and funded by the Bill & Melinda Gates Foundation, the program distributes new rice varieties tolerant of stresses such as the droughts and floods, salinity, and toxicity, to millions of farmers coping with these stresses.
STRASA began at the end of 2007 with IRRI in collaboration with AfricaRice. Conceived as a 10-year project with a vision to deliver the improved varieties to at least 18 million farmers on the two continents, the first two phases of the project have been funded with about US$20 million each.
The Bill & Melinda Gates Foundation is funding the third phase of the IRRI-led project with US$32.77 million through 2017.
Rice is the most important human food crop in the world, directly feeding more people than any other crop. In 2012, nearly half of world’s population, more than three billion people, relied on rice every day.
Rice is produced in a wide range of locations and under a variety of climatic conditions, from the wettest areas in the world to the driest deserts. Thousands of rice varieties are cultivated on every continent except Antarctica.
But as the climate changes, more varieties are being developed to help farmers produce their crops regardless of droughts that shrivel the rice plants and floods that rot them.
About three years into the STRASA program, in May 2011, Bill Gates described how he sees the revolution in rice production.
“What’s going on right now in Africa and South Asia is not a collection of anecdotes about improvements to a few people’s lives,” Gates said. “This is the early stage of sweeping change for farming families in the poorest parts of the world. It’s an historic chance to help people and countries move from dependency to self-sufficiency – and fulfill the highest promise of foreign aid.”
STRASA in Africa
Gary Atlin, senior program officer with the Bill & Melinda Gates Foundation, told the 3rd Africa Rice Congress held in October 2013 in Yaoundé, Cameroon, “The best adaptation to climate change is a breeding and seed system that rapidly develops, deploys, and then replaces varieties so that farmers will always have access to varieties adapted to their current conditions.”
This strategy is at the heart of STRASA, which helps smallholder farmers who are vulnerable to flooding, drought, extreme temperatures, and soil problems, such as high salt and iron toxicity, that reduce yields.
Some of these stresses are forecast to become more frequent and intense with climate change.
Climate change is already having a negative impact on Africa through extreme temperatures, frequent flooding and droughts, and increased salinity according to Baboucarr Manneh, irrigated-rice breeder at Africa Rice Center and coordinator of the African component of the STRASA project.
More than 30 stress-tolerant rice varieties have already been released in nine African countries with support from the STRASA project, said Dr. Manneh.
“One of the key impact points for STRASA will be the quantity of seed produced and disseminated to farmers,” said Dr. Manneh. “As seed production continues to be a major bottleneck in Africa, the main thrust of our recent STRASA meeting was to help countries develop seed road maps.”
Sometimes, various stresses, such as salinity, cold, submergence, and iron toxicity, can occur at the same time.
“That’s why the third phase of the STRASA project will focus on breeding for multiple stress tolerance,” Dr. Manneh explained.
STRASA in India
“Use flood- and drought-tolerant rice to get maximum profit from your small landholdings in the stress-prone areas of Bihar,” said Radha Mohan Singh, Union minister for agriculture and farmers welfare, to a gathering of more than 1,000 farmers at the foundation ceremony of the National Integrated Agriculture Research Centre in Motihari, Bihar, India last August.
Minister Singh told the farmers of how scientists from the Indian Council of Agricultural Research took him to a pond planted with a new flood-tolerant rice variety that was fully submerged in water for 15 days. “I immediately asked them, ‘Why this much water? Wouldn’t the rice rot?’”
But the crop variety that survived 15 days of submergence had “very good yield,” the scientists said.
These flood-tolerant seeds now are available for farmers in Motihari. Trials of a drought-tolerant rice variety are also being conducted in several Motihari villages.
“Following the Minister’s speech, the IRRI booth received a rush of inquiries from farmers,” said Dr. Sudhanshu Singh, International Rice Research Institute scientist and rainfed-lowland agronomist for South Asia, who represented the Institute during the foundation ceremony and exhibit.
About 10 million of the poorest and most disadvantaged rice farmers have been given access to climate-smart rice varieties.
“Swarna-Sub1 changed my life,” said Trilochan Parida, a farmer at the Dekheta Village of Puri in Odisha, India.
Floods ravage Parida’s rice field every year. Flooding of four days or more usually means a loss of the crop as well as of any expected income. But in 2008, Parida saw his rice rise back to life after having been submerged for two weeks.
Swarna-Sub1 is a flood-tolerant rice variety developed by the Philippines-based IRRI. It was bred from a popular Indian variety, Swarna, which has been upgraded with SUB1, the gene for flood tolerance.
“Under the past phases of the project, 16 climate-smart rice varieties tolerant of flood, drought, and salinity were released in various countries in South Asia. About 14 such varieties were released in sub-Saharan Africa. Several more are in the process of being released,” said Abdelbagi Ismail, IRRI scientist and STRASA project leader.
In addition to improving varieties and distributing seeds, the STRASA project also trains farmers and scientists in producing good-quality seeds. Through the project’s capacity-building component, 74,000 farmers, including 19,400 women farmers, underwent training in seed production.
3,000 Rice Genomes Sequenced
Now a scientific advance has made even more progress possible.
A remarkable 3,000 rice genome sequences were made publicly available on World Hunger Day May 29, 2014.
This work is the completion of stage one of the 3000 Rice Genomes Project, a collaborative, international research program that has sequenced 3,024 rice varieties from 89 countries.
The collaboration is made up of the Chinese Academy of Agricultural Sciences (CAAS), the International Rice Research Institute (IRRI), and the Beijing Genomics Institute (BGI), and is funded by the Bill & Melinda Gates Foundation and the Chinese Ministry of Science and Technology.
IRRI Director General Dr. Robert Zeigler said, “Access to 3,000 genomes of rice sequence data will tremendously accelerate the ability of breeding programs to overcome key hurdles mankind faces in the near future.”
“This collaborative project,” said Zeigler, “will add an immense amount of knowledge to rice genetics, and enable detailed analysis by the global research community to ultimately benefit the poorest farmers who grow rice under the most difficult conditions.”
The 3000 Rice Genomes Project is part of an ongoing effort to provide resources for poverty-stricken farmers in Africa and Asia, aiming to reach at least 20 million rice farmers in 16 target countries – eight in Asia and eight in Africa.
Dr. Jun Wang, director of the Beijing Genomics Institute, said, “The population boom and worsening climate crisis have presented big challenges on global food shortage and safety. BGI is dedicated to applying genomics technologies to make a fast, controllable and highly efficient molecular breeding model possible.”
“This opens a new way to carry out agricultural breeding. With the joined forces with CAAS, IRRI and Gates Foundation, we have made a step forward in big-data-based crop research and digitalized breeding,” said Dr. Wang. “We believe every step will get us closer to the ultimate goal of improving the wellbeing of human race.”
