Inequality hotspot map shows where women in agriculture are hit the hardest by the climate crisis

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Women working in agricultural sectors in low- and middle-income countries are disproportionally at risk from climate change induced hazards, such as droughts, floods, or shortened crop-growing seasons. Now, researchers have developed a map showing localities where climate change risk for women in agri-food systems is especially high. Ranking 87 countries, they found that women in central, east, and southern Africa, as well as west and south Asia are at particular risk. Threats posed by the climate crisis disproportionally affect certain communities and social groups that are more exposed. People living in low- and middle-income (LMIC) countries are at heightened risk. Within these countries, women typically face higher climate risk than men. To show where women working in agri-food systems – systems that encompass production, but also post-harvest handling and distribution – are most threated by climate change, an international team of researchers has developed a hotspot map that identifies and ranks localities by threat level. “We show that significant climate hazards, high exposure faced by women in agri-food systems, and high vulnerability faced by women due to systemic gender inequalities converge particularly in central, east, and southern Africa, as well as in […]

New study highlights need to address risk of continued global warming after net zero

by Liad Hollender, Frontiers science writer Image: Shutterstock.com The UN Climate Panel’s latest best estimate is that global warming will end once we reach net zero CO2 emissions – but a study in Frontiers in Science warns significant warming could still occur. Researchers including those from Imperial College London and University of Exeter assess factors controlling global temperatures post ‘net zero’ and offer a pioneering framework for better estimating climate change risks. These risks must inform climate mitigation and adaptation policies to protect future generations.  From scorching heatwaves to torrential downpours and devastating storms, the disastrous effects of global warming are sweeping across the world. Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO2 emissions from human activities to ‘net zero’ – where the amount of CO2 we emit into the atmosphere is equal to the amount we remove from it. To keep within the 1.5°C limit of the 2015 Paris Agreement, this needs to happen as soon as possible.   Though the scientific community’s current best estimate from models is that global warming will stop at net zero, an article published in Frontiers in Science raises a red flag.  […]
