Wetlands in Drylands: Hidden Hotspots of Carbon Sequestration and Storage?

Although the term ‘wetlands in drylands’ sounds like a contradiction, many drylands host a range of ephemeral wetlands. Pans, for example, are widespread features in many drylands, representing topographic depressions of varying size and shape that host ephemeral, sometimes saline, bodies of shallow water following infrequent precipitation or river flooding …

The Influence of Trees, Shrubs and Grasses on Micro-Climate, Soil Carbon, Nitrogen and CO2 Efflux: Potential Implications of Shrub Encroachment for Kalahari Rangelands

Shrub encroachment is a well-documented phenomenon affecting many of the world’s drylands. The alteration of vegetation structure and species composition can lead to changes in local microclimate and soil properties which in turn affect carbon cycling. The objectives of this paper were to quantify differences in air temperatures, soil carbon, …
