"Globally surface and groundwater flows (blue water) have been greatly impacted by human induced changes during the Anthropocene". See more details in our new article published in Nature Sustainability.

We evaluated 14 machine-learning models to downscale land surface temperature (LST) and several predictors of its variability. Among other key results, we found that dust transport from the Sahara reduced solar radiation, producing cooler LST. sciencedirect.com/science/articl…

Regional hydrological models are more suitable in downscaling GRACE data for localized water storage assessments. See our new article in Journal of Hydrology. sciencedirect.com/science/articl…

In our recent study published in One Earth, we improved the representation of water storage changes in climate models whilst reducing uncertainties in water budget closure. The article is freely available. cell.com/one-earth/full…

Climate & land use changes are causing significant alterations in global terrestrial water storage impacting extreme weather events such as floods and droughts, a ARI-led study by Dr Chris Christopher E. Ndehedehe & Dr Adeyeri Oluwafemi has found doi.org/10.1016/j.onee… news.griffith.edu.au/2024/01/09/pro…

Interesting piece about our recent work published in One Earth. sciencedirect.com/science/articl…

The current rules governing the administration of groundwater licencing in areas without a Water Allocation Plan in Australia’s Northern Territory will not deliver on the need to protect important ecological and Indigenous socio-cultural values. tandfonline.com/doi/full/10.10…

Please join us Wednesday next week at the Australian Rivers Institute for this interesting seminar. See event details below.

Our understanding of extreme climatic indices (e.g., consecutive wet day index, simple daily intensity index, etc.) can provide better insight into climate change and its drivers. See our new study below. link.springer.com/article/10.100…

New article led by my PhD student (Ikechukwu Kalu) used data products from the Australian Water Outlook to improve the spatial resolution of GRACE data. Please see more details in Scientific Reports below. nature.com/articles/s4159…

Last week, me and my PhD student (Ikechukwu Kalu) attended the Advancing Earth Observation Forum in Adelaide. It was great to see the amazing science from the community and to meet so many wonderful people.

We have introduced a new method to combine drought indices from GPS- and GRACE-based vertical displacements to assess hydrological drought. The article is freely and publicly available in Remote Sensing of Environment. sciencedirect.com/science/articl…

Findings from our recent work suggests future erosion in West Africa is projected to increase by about 15% under SSP 370. See published article in Science of The Total Environment below. sciencedirect.com/science/articl…

Congratulations to my PhD student, Ikechukwu Kalu, for this outstanding piece of work, now published in Water Resources Research! Article is freely available for download. agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

High variability in soil moisture increases the uncertainty in GRACE-based groundwater estimates. See our new article published in Journal of Hydrology. sciencedirect.com/science/articl…
