Nature Sustainability, Published online: 30 September 2026; doi:10.1038/s41893-026-01956-y The impacts of extreme natural events are dramatic for both people and physical infrastructure. More can and should be done to contain the damage and prevent loss of life.
Nature Sustainability, Published online: 30 September 2026; doi:10.1038/s41893-026-01936-2 Restoration initiatives are important for progress towards climate and biodiversity policy goals; however, whether they lead to the displacement of tree loss elsewhere (leakage effect) is still unclear. This study examines the leakage impacts of restoration projects in sub-Saharan Africa.
Nature Sustainability, Published online: 30 September 2026; doi:10.1038/s41893-026-01941-5 As countries expand renewable energy to reach net zero, finding suitable land is becoming increasingly challenging. A new China-wide optimization study shows that land constraints redirect renewable development, increase transmission needs and raise 2060 system costs by up to 4.1%.
Nature Sustainability, Published online: 28 September 2026; doi:10.1038/s41893-026-01937-1 The collapse of the western Baltic herring fishery by the year 1570 caused large disruptions. Using a time series of Baltic herring catches spanning 450 years, this study examined the socioeconomic and environmental drivers of the collapse, offering lessons for fisheries management today.
