The Radio is an instrument of communication that has percolated to all the strata of the diverse Indian society. Its position has been consolidated through history as a regular companion and a source of information and entertainment. Its affordability, accessibility and non-reliance on costly resources have ensured its presence in almost all the households. It has become indispensable from kitchens, family rooms and even workspaces. It is one of the few or rather the only medium of communication after the print media wherein information dissemination still is primary and entertainment a secondary requirement, especially the rural areas.

Contemporary radio is under-studied by academic researchers, while on the contrary it expresses great exigencies of knowledge. Media studies examined deeply radio when it was the mainstream medium, i.e. in the Thirties, especially in the US also for marketing needs of a largely commercial broadcasting system.

Historical background The BBC Radio Science Unit has its roots in two radio networks, going back more than 40 years. In the late 1950s, BBC External Services (now World Service), appointed a science correspondent and began a weekly science magazine programme. Initially called `Science and Industry', it changed its name in about 1964 to `Science in Action'. It is still running today, after more than 2000 editions, probably making it the longest running science show on radio.

The international symposium Science on air: the role of radio in science communication was held in Trieste on 1 and 2 October, 2004. To our knowledge, it is the first conference ever specifically held on science in radio, and it is certainly the first time science radio journalists, researchers, and media experts from 16 different countries met to discuss their journalistic practice and the role of radio in science communication. The main results are presented in this section.

The objective of the present paper is an attempt to measure the public understanding of science in the area of health and hygiene and test the efficacy of "cultural distance model". A pre-tested open-ended questionnaire was used for administering cross-sectional surveys at a religio-cultural festival in India. 3484 individuals were interviewed and responses were coded and entered to construct computer database. The data was used for determining the cultural distance of five scientific concepts from the quotidian life of the target population. In developing countries, the formal system of modern education operates as a strong determinant in shaping cultural structures of thoughts prevalent among the citizens. There exists a cultural distance between the scientific structure of configuring natural occurrences and peoples' complexity of thoughts. The distance varies significantly across the concepts that were subjected to the inspection and is a function of the nature of scientific information.

The scientific institution in Brazil is marching to a good rhythm. Despite problems in funding (and in the very irregular distribution of such funds), universities and private research centers changed and grew over the last few years. In 1999, Brazil (whose external debt is over 50% of GDP), invested 0.87% of GDP in Research & Development: a percentage comparable to that of several Mediterranean countries.

A feature of the management of natural resources in the coastal zone is that it involves multiple stakeholders. It has been suggested that the effectiveness of coastal management relies on the cooperation of this multitude of stakeholders in decision-making. This study reports on the findings of an investigation into the modes of interaction used by coastal researchers to communicate with stakeholders. A qualitative research methodology was used through both telephone and in-depth face-toface interviews to elucidate the mechanisms of interaction and, in turn, produce a typology of interaction modes. It was found that there were five main modes of interaction: Limited; Mediator Achieved; Key Stakeholder; Full Interaction and Mixed and that the discipline area in which the researcher worked did not dictate their preferred mode of interaction. It was concluded that although there are a number of limitations to effective participation, these interactions have significant implications for meaningful participation in the management of coastal resources.

The Regional Park of the Po River Delta1 was set up in 1988 (it belongs to a Consortium of Public Bodies). It extends over 54,000 hectares of land and stretches across 45 km of the Italian Eastern coastline (45 km of the more than 90 km that go between the provinces of Ferrara and Ravenna)2 and is one of the largest and most significant natural parks in Italy.
