• Enhancing urban water security in Mexico — Water security is defined as the capacity of a population to safeguard sustainable access to adequate quantities of acceptable quality water. Growing populations and the increasing trend of human migration from rural to urban environments is leading to an expansion of the metropolitan landscape, which threatens water security. In semi-arid regions, water availability can be highly variable and a lack of sustainable water resource planning in metropolitan design has further exacerbated the problem. This Urban water security consortium of 26 UK and Mexican researchers is driven by a single goal; to enhance regional water security in semi-arid regions through improved metropolitan design. Our research base is informed by comprehensive empirical studies and high-quality data evaluation. We strive to build productive relationships with stakeholders and make a positive impact on society. This consortium feeds advice and expertise into the ReTGIA Thematic network.
• Philippines Groundwater Outlook (PhiGO) — Water security is of particular concern for Filipino cities, which have been designated amongst the worst in Asia for urban water security. Changing climate and increasing urban population density will put more stress on their water resources, having an acute impact on valuable groundwater resources. Through a programme of data gathering, knowledge exchange, fieldwork, numerical modelling and stakeholder engagement the PhiGO project seeks to undertake assessments of population and climate change impacts on regional groundwater resources and translate these into usable forecasts of flood and drought risk. To better understand the potential socio-economic impacts of groundwater level extremes and potential water management strategies, PhiGO is also focussed on quantifying the cascading impacts of flood and drought through key infrastructure and analysing the cost-benefit of differing water management and urban planning scenarios.
• Coastal evolution — Investigating the influences of oceanic and climatic variables on shaping soft sediment coastlines using the shoreline evolution models. These models simulates shoreline development in response to changes in deep-water wave climates, geological settings and beach properties. They are well suited to simulating decadal to centennial scale responses to change at the regional scale, for example from the addition or removal of coastal defenses. They are also well suited to improving our conceptual understanding of mesoscale coastline dynamics. These models are currently being further developed under the BLUEcoast project and are strengthening our ability to understand the resilience and recovery of UK and global coastlines to change.
• Decadal scale landscape evolution — The CLiDE environmental modelling platform is a geomorphological simulator that allows a variety of Earth systems, and their interactions, to be explored. The platform includes a variety of modules, representing key terrestrial Earth system components, which may be switched on/off as required. This versatility allows CLiDE to explore a variety of scenarios at a range of timescales. CLiDE may be used to further our understanding of a particular system or to simulate the impacts of changing driving conditions on terrestrial systems. The latter is particularly relevant to the current, unprecedented, rapidly changing environment we are now experiencing. This year the project is focussed on the representation of physical anthropogenic processes on groundwater, surface water and sediment fluxes in landscape evolution models.
