Did you know that rice contributes up to 17 percent of human-induced methane? Sugars produced by photosynthesis leak from the plants’ roots into the soil, where they are consume by methane-producing microorganisms, says an article this week in the New Scientist, which reports that researchers in Sweden, China and the US have developed a new strain of GM rice that, equipped with a gene from barley, increases yields and produces only 1 percent of the greenhouse gas. If it is widely adopted, it may help mitigate climate change. One obstacle: China does not yet allow GM rice production. According to another article, researchers are looking for a way to breed the same rice using conventional methods to bypass GM restrictions, but it may take another ten years. Another rice discovery announced this week: researchers have discovered a bacterial signal that, when recognized by rice plants, allows them to resist Xanthomonas oryzaepv.oryzae, a pathogen that causes a devastating blight. This is not just a breakthrough for one of the world’s staple crops: discovering this trigger may help keep such perennial grasses as Miscanthus and switchgrass – grown as biofuel feedstock – healthy.
Meanwhile, scientists at the International Maize and Wheat Improvement Center (CIMMYT) are on the verge of finding a seed resistant to maize lethal necrosis, a disease that has destroyed millions of dollars worth of maize crops in sub-Saharan Africa. ‘’We have a responsibility to work together and control the spread of this virus,‘ says Dr. Prasanna Boddupalli, director of CIMMYT, in the report, urging stakeholders to continue working to develop resistant maize varieties, lest the disease spread.
On the sustainable agriculture front, scientists at Rothamsted Research have developed an effective climate-smart cropping system that lets smallholder African farmers to sustainably increase production. Called push-pull companion cropping, the technique uses intercropping of carefully selected companion crops – specifically cereals with a pest-repellent plant that repels stemborers from the cereal crop. An attractant crop is planted around the border to attracting and trap the pests. Desmodium, which is used as the pest-repelling plant, is also a nitrogen-fixing legume.
Contributions from B4FA Fellows this week include pieces from Michael Ssali on why growing clonal Robusta coffee is advantageous and a piece about whether farming in wetlands contribute to development. And Lominda Afedraru checks in with a piece about Makerere University setting up a climate centre. Besides offering courses related to crop and animal production, agribusiness and economics, agricultural engineering, geography and forestry and so on, the Centre aims to equip its students to reach out to farming communities affected by climate change. She also writes a piece about transgenic gene editing and whether it might someday be used in Ugandan biotech.
We’re also pleased to note that Michael Ssali himself is featured in a Daily Monitor story: “How a journalist’s newsroom career supported his ambition to be a farmer“. It reports on how, having covered many successful farmers, Ssali was inspired to invest in farming, too.
