The core objective of go-CAM is to develop, implement and apply multicriteria governance optimisation for sustainable water use in various coastal regions around the world. By linking modern methods that support decision-making and action with findings from hydrosystems modelling, the project will produce an integrated, transferable coastal zone management system. This planning tool will be part of an online dialogue platform called Coastal Aquifer Management (CAM). Using case studies in Brazil, Turkey and South Africa, the governance optimisation and software packages that go-CAM will develop should become established internationally. Modern hydrological, hydrogeological and geological models will form the basis for estimating water resources and demand in coastal regions. With the help of a multicriteria decision analysis, go-CAM will establish regional courses of action that will then be transferred into practice using the CAM dialogue platform. Accompanying workshops with the various user groups will increase acceptance for the methods and results. A PhD programme with the project’s international partners should guarantee that the model can continue to be applied even after go-CAM has finished.
Priorities
Develop, calibrate and apply hydrological, hydrogeological and geological models in coastal areas
Estimate current water resources and demand, and the corresponding trends, while taking account of various impacts and usage claims
Establish regional courses of action using multicriteria decision analysis
Transfer the CAM dialogue platform from northern Germany (where it will be developed) and the underlying methods to international partner regions
Relevance
Coastal regions present special challenges when it comes to the sustainable use of water resources. These include climate change, changing sea levels, salinization risk, high discharge of nutrients from agriculture, low-lying ground and – not least – high population density and high water demand in industry. Overusing water resources inevitably leads to conflicts over its use. Comprehensive and sustainable governance of water supplies is therefore crucial. A major challenge here is to take account of the relevant factors for modelling the entire system so that a multicriteria decision analysis can be used to establish regional courses of action. Other challenges include preparing the model results for practical use, and achieving acceptance among the user groups.

IFAT Africa is a forum and trade exhibition for environmental technologies that takes place once a year in Johannesburg. On 9th of July 2019, Dr. Konstantin Scheihing presents in cooperation with the Buffalo City Metropolitan Municipality the GRoW project go-CAM at the IFAT Africa.
A short summary of GRoW’s first year paints a positive picture. The research projects have started well and are also attracting a great deal of international attention. They have begun developing partnerships and networks with public and private international stakeholders, and are finding support among global environmental organisations. This keen interest shows that GRoW is doing relevant, topical work – primarily because it is successfully developing local and regional, globally transferrable solutions for protecting water resources.
