International hydroacoustic surveys have been conducted in the Baltic Sea since 1978. The starting point was the cooperation between Institute of Marine Research (IMR) in Lysekil, Sweden and the Institute fur Hochseefisherei und Fishverarbeitung in Rostock, German Democratic Republic in October 1978, ¨ which produced the first acoustic estimates of total biomass of herring and sprat in the Baltic Main basin (H˚akansson et al., 1979). Since then there has been at least one annual hydroacoustic survey for herring and sprat stocks and results have been reported to ICES. The Baltic International Acoustic Survey (BIAS), is mandatory for the countries that have exclusive economic zone (EEZ) in the Baltic Sea, and is a part of the Data Collection Framework as stipulated by the European Council and the Commission (Council Regulation (EC) No 199/2008 and the Commission Data Collection Framework (DCF) web page1 ). IMR in Lysekil is part of the Department of Aquatic Resources within Swedish University of Agricultural Sciences and is responsible for the Swedish part of the EU DCF and surveys in the marine environment. The Institute assesses the status of the marine ecosystems, develops and provides biological advices for managers for the sustainable use of aquatic resources. The BIAS survey are co-ordinated and managed by the ICES working group WGBIFS. The main objective of BIAS is to assess herring and sprat resources in the Baltic Sea. The survey will provide data to the ICES Baltic Fisheries Assessment Working Group (WGBFAS).

The IENE 2014 conference puts emphasis on the "greening" of transport infrastructure: both in respect to a wiser use of marginal infrastructure habitats to favour biodiversity and certain ecosys- tem services, and in respect to a more permeable and safer infrastructure that minimises the direct impact on wildlife. Transportation and infrastructure are recognised as signi cant drivers in the global loss of biodiverity. Their impacts on nature are well described and there is ample evidence for the negative effects of traffic and transportation infrastructure on nature. Even though roads and railroads may occupy but a small proportion of an area, they a ect the entire landscape, cause the death of millions of wild animals, and disturb surrounding habitats through pollution, noise and alien species. The overall impact is evident, but there are means to minimise the pressure, to adjust infrastructure facilities and, to some degree, introduce beneficial services for wildlife. Such measures can and should be implemented as a standard in infrastructure development and maintenance. Knowledge about their functionality and e cacy is, however, not always satisfying. Technical innovations and new mitigation concepts need to be tested and evaluated. Their func- tionality and e ectiveness also depends on the interplay between the transport sector and other sectors of society. Communication, knowledge transfer, and public education are just as essential here, as legal frameworks, policy, technical development and environmental science. European policy (e.g., Green Infrastructure) is developing clearly in this direction, recognizing the transport sector and transportation facilities as important players in the endeavour towards a greener and sustainable future. Obviously, this calls for international collaboration in research and practice, for enhanced exchange of knowledge between disciplines, and for the development of harmonised standards and pro- cedures that can be referred to by international actors. IENE provides this interdisciplinary arena through its conferences and workshops. The IENE 2014 international conference emphasises that transport infrastructure can be planned and designed as an ecologically well-adopted, safe and e cient system, while acknowledging that certain impacts can never be avoided. IENE, together with the Swedish Transport Administration, the Swedish University of Agricultural Sciences, the Danish Road Directorate and numerous other partners, invites scientists, practitioners and planners, governmental agencies and private companies, NGO's and anybody with an interest in the above to the IENE 2014 conference in Sweden. We welcome new partner- and sponsorships and o er a well-approved and international network for communication and presentation.
