Regional vegetation and climate changes are inconsistent with global trends, but what now
Global greening is a trend attributed to rising atmospheric CO 2 , warming and land-use change. However, certain regions may diverge from this pattern. South Africa, which occupies 0.82% of the global terrestrial surface area with ca. 10% of global Plantae species, is considered especially vulnerable to climate change. We analysed enhanced vegetation indices (EVI) from 1984 to 2021 across protected areas, correlating this with climate data from g…
Grassland albedo as a nature-based climate prospect
Nature-based solutions for mitigating climate change focus largely on land management to reduce carbon emissions and enhance carbon sequestration. Tree planting, commonly advocated for carbon offset, threatens grassland biodiversity and may induce positive radiative forcing (warming) by lowering albedo. Before making decisions about land-use changes in grasslands, an understanding of the fine-scale albedo of grassy versus woody vegetation is need…
Wilder rangelands as a natural climate opportunity
Rangelands face threats from climate and land-use change, including inappropriate climate change mitigation initiatives such as tree planting in grassy ecosystems. The marginalization and impoverishment of rangeland communities and their indigenous knowledge systems, and the loss of biodiversity and ecosystem services, are additional major challenges. To address these issues, we propose the wilder rangelands integrated framework, co-developed by …
