V. MOST SIGNIFICANT ACHIEVEMENTS AND DISTINCTIONS:
Ling Li is currently Professor and Chair in Environmental Engineering at the University of Queensland. He received his PhD in Environmental Engineering in 1998 at The University of Western Australia, Australia. His principal research interests lie in mathematical modelling of complex environmental systems. His current research focusses on the groundwater dynamics that underlie the behaviour of key coastal environments and ecosystems. His work addresses fundamental aspects of ocean-land interactions and has provided a key theoretical base for current scientific view of the dynamics of coastal shallow aquifers, and interactions between aquifers and coastal seas. Professor Li has made several breakthroughs in understanding complex nearshore groundwater flows. His theme is to improve our understanding of the important role of subterranean estuaries in controlling the exit condition of the subsurface transport pathway of landsourced chemicals to coastal waters via submarine groundwater discharge. Through collaboration with scientists from China, he uncovered a major groundwater system underneath the Badain Jaran desert in western Inner Mongolia. This work, published in Nature, established for the first time the link between the groundwater system and the unique landscape of the desert, which has the world’s highest stationary sand dunes and numerous lakes despite the wind and high potential evaporation. The discovery has important implications for regional ecology and water resources plan in north-western China. He has published over 100 refereed research articles mostly in leading discipline journals and delivered a number of keynote addresses in international conferences.

VIII. VISIONS (related to China and Australia from the area of expertise):
Much needed research on coastal wetlands: The Ramsar Convention on Wetlands has identified important roles of coastal wetlands at the land-ocean interface (www.ramsar.org). These coastal ecosystems are of great significance for China and Australia environmentally, economically and socially. In particular, salt marshes, as important intertidal wetlands, are highly productive with a range of plant species. They serve as essential habitats for many intertidal fauna and influence greatly the productivity of coastal waters through nutrient exchange. The marsh ecosystem plays a critical role in maintaining coastal biodiversity. Salt marshes are an important part of the global biogeochemical cycle. They may act as carbon sinks, moderating the greenhouse gas emission and global warming. Moreover, salt marshes can function as filters of particles and contaminants in terrestrial water discharging to the sea, protecting coastal water quality. Under the threat of sea level rise, salt marshes provide protection for the coastal zone through adaptation.

China and Australia both have a large number of marshes listed by the Ramsar Convention as coastal wetlands of international importance. However, loss and degradation of these marshes has occurred due to competing land uses and ignorance of wetland values:

• Land use impacts within catchments, leading to increased fine sediment and nutrient loads.
• Drainage and/or filling for agricultural, urban and/or industrial development.
• Degradation by pollutants such as acid drainage, nutrients and metal contaminants.
• River regulation, barrages, infrastructure and floodplain structures.
• Intensive uses for aquaculture, dredging and shipping port infrastructure.

To properly assess and mitigate these impacts, it is essential to understand the flow and transport processes in the marsh soil. This project examines in detail these processes and will lead to (1) better understanding of the marsh’s response to anthropogenic stress; and (2) improvement of strategies and methods for marsh wetland preservation and restoration.

On a related issue in our coastal zone, water pollution in many areas is a serious environmental problem, threatening marine and estuarine ecosystems. The source of the excessive nutrients in coastal water can be from coastal wetlands. So far this source has not been well quantified and often ignored in studies of coastal water quality. The proposed project examines flow and transport processes underlying the chemical transfer from salt marshes to the ocean and will contribute to: (1) better understanding of the pathway of land-derived nutrients and contaminants entering coastal waters, leading to improvement of strategies for sustainable coastal resources management and development; (2) useful information for integrating the management of upland and lowland catchment areas; and (3) development of sound risk assessment methods and mitigation plans for coastal and estuarine pollution.

Salt marshes are also complex hydrological systems characterised by strong, dynamic interactions between surface water and groundwater. Our current lack of understanding of the complex marsh hydrology has seriously hindered the exploration of these wetlands’ ecological functions and effort to reverse a worldwide trend of declining salt marshes. Two long-standing hypotheses about plant zonation and nutrient outwelling have been in the centre of many previous studies. However, these studies lacked proper understanding and representation of the flow and transport processes in the marsh soil, and failed to establish sufficiently the link between the marsh’s ecological functions and hydrological conditions. I propose a research program to address this major research gap. The outcomes will advance the research on coastal wetlands and contribute to fundamental understanding of ocean-land interactions. In the long term, the work will assist in assessing, preserving and restoring coastal marsh wetlands, and determining the sources and fluxes of chemicals from these wetlands to coastal waters. The proposed study will showcase both countries’ capacity for cutting-edge research to achieve environmental innovation and management, and increase their capacity for tackling water environment issues of international significance.
