The work done at GEM is
presented at several dedicated websites.
GEM is involved in a number
of ongoing research
projects. The main areas of interest are ecological modelling and related aspects, such as
data gathering and analysis, and modelling applications for management. Current research
is focused on developing and applying an ecological modelling tool (EcoWin2000) to Regions
of Restricted Exchange, and using new data gathering techniques (mainly Remote Sensing and
Geographic Information Systems) to obtain spatially distributed, high resolution data for
modelling. Data about ongoing research is available on-line.
Ecosystem Approach for Sustainable Aquaculture
This project (2004-2007) is financed by the
European Union FP6 programme. The project takes an ecosystem approach to aquaculture, by 1) identifying plausible quantitative indicators of the effects of aquaculture on ecosystems through a process of expert working groups, workshops and meetings, 2) identifying indicators of the main drivers of ecosystem change affecting aquaculture, including natural and environmental pressures, 3) assessing
both sets of indicators using existing datasets, considering each in the context of appropriate selection criteria, 4) developing a range of tools, particularly models, that encapsulate best process understanding at a wide range of scales, 5) testing these models and indicators in a wide variety of field locations across Europe (~10) encompassing major culture species and technologies, and covering a wide spectrum of environment
types, and 6) using these data to test and select the final “toolpack” of models and
Carrying capacity of key European coastal zones
This project (2005-2007) is financed by the
European Union CRAFT programme. KEYZONES aims to characterise the carrying capacity of key European coastal zones for commercial production of bivalve shellfish, producing powerful tools which would enable shellfish producers in the targeted areas to optimise production capacity, recruitment of young stock, and quality whilst reducing waste; and increase the scope and credibility of generic ecosystem models with a consequent application to the wider industry and other stakeholders in coastal zones.
Sustainable options for PEople, catchment and Aquatic Resources
This project (2004-2007) is financed by the
European Union INCO-DEV programme. SPEAR aims to develop and test an integrated framework for interpreting coastal zone structure and dynamics, in areas where communities primarily depend on marine resources. This framework accounts for watershed interactions, ecological structure and human activities. The interdisciplinary approach used combines natural and social sciences, and addresses the complex scaling issues inherent in integrated management.
Sustainable Mariculture in Northern Irish Lough Ecosystems
(2004-2006) is financed by the Department of Agriculture and Rural
Development of Northern Ireland. The objective is to establish the
environmentally sustainable carrying capacity for shellfish
aquaculture for five Northern Irish loughs: Carlingford, Strangford,
Belfast, Larne and Foyle. This is being carried out using a range of
modelling approaches, combined with experimental and field data
This project (2002-2005) is financed by
the European Union INCO-DEV programme. The objectives are to design, implement and validate a generic
catchment-to-coast integrated planning and management support system for the southern
African region, which can also be implemented beyond the region.
These capabilities will
promote sustainable resource management on a whole catchment basis, specifically including
the coastal zone.
GEM has participated in several projects
involving estuarine analysis and ecological modelling, who provided useful scientific
information about the systems under study, and insights about the analytical and
simulation methodologies used. Some of the project results are available on-line for
Oceanographical Applications to Eutrophication in Regions of
Project OAERRE aims
to understand the relationships between the physical, chemical and ecological processes
occurring in RREs, with the goal of producing a simple but accurate RRE model applicable
for management purposes. GEM is responsible for studying the Ria Formosa site, as well as
deriving general equations for the model.
Carrying Capacity Assessment of Chinese Bays
This project studied two Chinese bays, Sanggou and
which are used for intensive aquaculture, and determined their carrying capacity in order
to provide management solutions. GEM was responsible for data management and ecological
modelling in the Sanggou Bay site.
European Salt Marsh Modelling
EUROSSAM studied several salt marshes throughout Europe, in order to gather information on
salt marsh processes. The final results were incorporated in a CD-ROM Decision Support
System, intended to serve as a management tool. GEM was responsible for creating an
organic matter cycling model in salt marshes.
Matter Cycling Models in Salt Marshes - final report
Much of the work done by GEM has been
presented at workshops or conferences. The slides making up several of
these presentations are available online:
