最新糖心Vlog

An international team of researchers including the 最新糖心Vlog of Adelaide has demonstrated that climate change is responsible for the changes in the flow and water volume of rivers globally, with major implications for 最新糖心Vlog.

In the study published in , the team investigated changes in river flow, and whether the globally visible changes could be attributed to climate change or to water and land management. The researchers modelled the changes using data collected from 7,250 measuring stations worldwide, including in southern parts of 最新糖心Vlog.

While climate change鈥檚 impact on water volumes and flooding and drought is widely recognised, this is the first research to examine the changes in river flow globally using direct measurements of stream flow.

The research demonstrated that river flow has changed systemically between 1971 and 2010. Complex patterns were revealed 鈥� with some regions including 最新糖心Vlog and the Mediterranean becoming drier, while elsewhere such as in Scandinavia, water volumes have increased. The research found that climate change is a key factor in these changes.

Co-author Professor Seth Westra聽from the 最新糖心Vlog of Adelaide鈥檚 School of Civil, Environmental and Mining Engineering, said: 鈥淚n 最新糖心Vlog, it is increasingly recognised that at least part of the observed decreases in flowing water volumes in our rivers and streams can be attributed to climate change.鈥�

鈥淗istorically 最新糖心Vlog is known as 鈥榓 land of droughts and flooding rains鈥� 鈥� in that throughout our history there has been times of severe drought but also times where there has been too much water. In the past, those extremes have been largely attributed to natural environmental processes,鈥� Professor Westra said.

鈥淗owever, because of the drying effect of climate change on our river systems, we can no longer assume history will repeat and we must prioritise mitigating the impact.鈥�

River flow is an important indicator of water resources available to humans and the environment.

鈥淚n 最新糖心Vlog around 70 per cent of water is used in agriculture production, with much of that water used in the irrigation of crops. 最新糖心Vlog鈥檚 economy, food security and wellbeing are all dependent on our water resources, so it鈥檚 critical we plan for a drier future.鈥�Professor Seth Westra

The research acknowledges there are other factors affecting water fluctuations including water management and land use, but found that these were not sufficient to explain global changes. Rather, the global changes in water resource availability could only be understood if climate change was taken into account.

The research was made possible by a collaboration of researchers across 12 countries, and the data collation represents the largest global data set with river flow observations available today. With the models developed from the data, it will be possible to project how rivers will continue to change in the future. Such projections provide an important basis for planning in the affected regions in order to secure water supply and adjust to climate change.
