Effects of drought on wetlands
- "'Globally, wetlands cover an area greater than 12.1 million square kilometres and deliver at least A$37.8 trillion (Int$27 trillion) in benefits per year, such as for flood mitigation, food production, water quality improvement and carbon storage.' Wetlands can suffer 'water droughts' both from the effects of a drier climate, and also when excessive water is extracted or diverted that would normally flow into them. The review paper describes how drought often leads to severe cracking and compaction, acidification, loss of organic matter, and enhanced greenhouse gas (for example methane) emissions." - Excerpt from University of Adelaide
