Advances in concepts and methods for the marine environment: implications for policy.
Science-based indicators aimed at measuring the sustainability of human activities on the environment have become of prime importance in the policy arena. At the international level, the Commission on Sustainable Development and the Convention on Biological Diversity and other Multilateral Environmental Agreements have recognised the need to develop a set of scientific indicators related to changes in biodiversity and other environmental issues able to direct policy decisions. In the marine realm, the study of the effects of both 'top-down' extractive activities such as fishing is more and more dealt with, in conjunction with 'bottom-up' activities such as nutrient loading and the effects on biogeochemical cycles, marine geochemistry and ecosystem structure and functioning of other pollutants and contaminants. 'Conventional' approaches such as the identification of taxa, model organisms and related methodologies will continue playing a key role for the monitoring of human-induced changes in the marine environment. On the other hand, newly developed disciplines such as genomics, proteomics and biodiversity informatics are increasingly looked at as a source of information and applications that can respond to questions and concerns by the policy community such as the need to adapt to global and climate change in the marine environment so as to mitigate its societal implications.
