Sydney, 21.03.2022 (SciDev.Net): Australian scientists have identified a novel combination of genetics that may help wheat survive in hot and dry conditions, thereby increasing yields and assisting farmers to adapt to climate change-induced heat and drought stress.

Wheat is the third-largest grain crop in the world, supplying about 20 per cent of the total calories and protein in the human diet worldwide, notes the research by CSIRO, Australia’s national science agency, published in Nature Climate Change on 7 March.

Researchers have identified three novel alternative dwarfing genes that enable wheat seeds to draw moisture stored twice as deep from the soil than current varieties. “We have genetics that can allow us to sow earlier and deeper up to 120 millimetres while keeping the plants short and allowing for very long coleoptile, which is the shoot that grows from the seed to the soil surface,” says Greg Rebetzke, co-author of the study and chief research scientist at CSIRO Agriculture and Food.

Sydney, 15.03.2022 (SciDev.Net): Women possess essential knowledge and skills, particularly at the local level, in the conservation and management of natural resources but have limited say in environmental decision-making, according to a report by UN Women Asia and the Pacific.

The report was published ahead of the 66th Commission on the Status of Women which is focusing on achieving gender equality in the context of climate change, environmental and disaster risk reduction policies and programmes. It says engaging women in these areas is critical to effective climate action.

“Women’s relationship to the environment is different to men’s in several complex but interlocking ways,” says Sarah Knibbs, officer-in-charge at UN Women Asia and the Pacific. “They are more exposed to some of the risks and also have a unique contribution to make to the solutions.”

‘Restore tropical forests’ to address climate change

Sydney, 23.02.2022 (SciDev.Net): Restoring biodiverse tropical forests could be a nature-based solution to remove carbon dioxide from the atmosphere and address climate change, scientists show in a study that simulates how forests will respond to future climate scenarios on earth.

According to the study, limiting global warming caused by human activity to less than two degrees Celsius requires rapid reduction in greenhouse gas emissions as well as reduction of carbon in the atmosphere.

Peter Talaas, secretary general of the World Meteorological Organisation, says that sea level rise and the melting of glaciers may continue until 2060 because of carbon dioxide in the atmosphere. “Of course, if we had carbon removal techs we could change the big picture, but so far that’s not the case,” Talaas said at a meeting ahead of the 28 February release of a section of the sixth report of the UN Intergovernmental Panel on Climate Change.
