The Chronicles Consortium hosts pan-African workshop 
The Chronicles Consortium, an initiative of the IAH-CGCC and UNESCO-IHP GRAPHIC programme, conducted a pan-African capacity-strengthening and knowledge co-production workshop at Sokoine University of Agriculture in Morogoro, Tanzania from the 10th to 12th of February, 2017.  This event was sponsored by the UK government under its UPGro programme and EPSRC, and DFID/The Royal Society AfriWatSan project. 40 participants from 12 countries in Africa took part and analysed multi-decadal, groundwater-level data (“chronicles”) from 9 countries including Benin, Burkina Faso, Ghana, Niger, Sénégal, South Africa, Tanzania, Uganda and Zimbabwe.  Participants comprised PhD students and more experienced researchers (mentors & supervisors) as well as representatives from government ministries and the private sector.  Training focused on the application of the water table fluctuation method for analysing groundwater-level records. A collaborative, pan-African analysis of multi-decadal groundwater-level records is in preparation and a number of participants is expected to contribute their national-scale analyses to an upcoming special section of Hydrogeology Journal.

GEWEX: Including Water Management in Large Scale Models 
Convened by the Global Land/Atmosphere System Study Panel (GLASS) and the GEWEX Hydroclimatology Panel (GHP), the IAH-CGCC through work conducted under The Chronicles Consortium delivered a keynote presentation by IAH-CGCC Co-Chair Taylor, Large-scale modelling of groundwater resources: Insight from a comparison of model data and in-situ observations.

43rd IAH Congress in Montpellier
The IAH Commission on Groundwater & Climate Change (IAH-CGCC) met at the 43rd Congress and discussed several key issues pertaining to the work of the IAH-CGCC including:
 networking: who is doing what in the field of research and practice evaluating the relationships between groundwater and climate change including both impacts and adaptations by compiling a list names of Commission members and their expertise by online survey; access to literature: both peer-reviewed publications behind firewalls and difficult-to-access grey literature reports in currently limited circulation – expand list of accessible databases on the website and provide a service of posting literature provided by commission members; and experience sharing: learn from other members about their works and activities (e.g. Josep Mas-Pla’s work in Catalonia) and providing links to existing webpages and literature sources under the listed commission members’ names.

Groundwater & climate change in IPCC AR5
The recently published 5th Assessment Report (AR5) of the Inter-governmental Panel on Climate Change (IPCC) on the impacts of climate change (Working Group II) reports for the first time on the impacts of climate change on groundwater in Chapter 3, Freshwater Resources. Previous assessment reports of the IPCC in 2007 (AR4) and 2003 (TAR) had concluded that little was known of the impacts of climate change on groundwater resources due to insufficient research. The IAH Commission on Climate Change led a recent review of climate change impacts that is cited frequently in the report. There two key conclusions regarding groundwater in the report: (1) “Climate change is projected to reduce renewable groundwater resources significantly in most dry subtropical regions”; and (2) “Reliability of water supply, which is expected to suffer from increased variability of surface water availability, may be enhanced by increased groundwater abstractions.”

The Chronicles Consortium launched at IAH 41st Congress in Marrakech
The IAH Commission on Groundwater and Climate Change organised a workshop at the 41st Congress of the International Association of Hydrogeologists (IAH) in Marrakech, Morocco on Sunday September 14th 2014, which focused on the analysis of long-term records of groundwater levels  from across Africa. The workshop was led by IAH-CGCC Co-Chairs (Taylor & Scanlon)  and Dr. Guillaume Favreau from the Institut de Recherche pour le Developpement (IRD), France. This event led to the creation of The Chronicles Consortium – an initiative of the IAH-CGCC and UNESCO-IHP GRAPHIC with support from IGRAC.

Commission on Groundwater & Climate Change (CGCC) & UNESCO-IHP GRAPHIC lead review paper, Groundwater and Climate Changepublished in Nature Climate Change
The IAH CGCC and UNESCO-IHP GRAPHIC Programme coordinated an expert review of the relationship between groundwater and climate change involving 28 authors from around the world. This review, initiated by a joint meeting at the AGU Fall Meeting in 2011, was published on 25th November in Nature Climate Change.

Commission on Groundwater & Climate Change (CGCC) & UNESCO-IHP GRAPHIC meet at the 39th Congress of the IAH in Niagara Falls
The CGCC and UNESCO-IHP GRAPHIC held a special session, Groundwater and Climate Change: Challenges and Opportunities, at the 39th Congress of the IAH and also met to discuss recent activities and progress as well as upcoming activities and plans for the IAH-CGCC. Of note is the recent publication of a volume of papers, Climate change effects on groundwater resources: a global-scale synthesis of findings and recommendations under the IAH’s International Contributions to Hydrogeology series (Volume 27) by CRC Press.  The book features an impressive array of 22 papers that draw from a broad range of scientific methods unraveling the effects of climate change on groundwater resources around the world. Second, the IAH-CGCC and UNESCO-IHP GRAPHIC led a critical review of the relationship between groundwater and climate change that has been accepted for publication in Nature Climate Change in late 2012. It is hoped that this messages contained in this manuscript might reach a wide audience including the authors of the 5th Assessment Report (AR5) of the IPCC due for publication in 2014.

Several activities of the IAH-CGCC are proposed over the next couple of years. These include special sessions at AGU 2012 Fall Meeting (IAH-CGCC Co-Chair Professor Bridget Scanlon for details), IAH 40th Congress in Perth 2013 (contact IAH-CGCC Co-Chair Richard Taylor for details), and a joint session with the Managed Aquifer Recharge Commission at ISMAR8 in China in 2013 (contact IAH-CGCC Co-Chair Jianyao Chen). In early November 2012, the IAH-CGCC will launch a new website ( in collaboration with the UNESCO-IHP GRAPHIC Programme. The new website will feature a login facility to register those interested in becoming members of the IAH-CGCC and allow registered members to engage with the site posting news of planned meetings, publications and projects. There are plans also to develop and maintain a database of relevant papers and reports on groundwater and climate change. Other strategic goals of the IAH-CGCC, discussed at the IAH Congress in Niagara Falls include: (1) developing benchmark datasets representing aquifer responses to climate variability and change as well as abstraction in different regions of the world; (2) resolving gap between recharge models and observations; (3) better constraining estimates of groundwater depletion and accumulation; and (4) improving our understanding of the impact of changing permafrost conditions on groundwater resources.
