A stakeholder approach to investigating public perception and attitudes towards agricultural biotechnology in Ghana

A stakeholder survey was conducted in Ghana to assess the level of public perceptions and acceptance of agricultural biotechnologies. A total of 100 respondents drawn from academia, Non-governmental organizations, business community, government and other stakeholders were interviewed on their views on self-protection attitudes, health and economic benefits, skepticism and optimism about agricultural biotechnologies as well as the level of confidence in existing government regulatory systems to protect society against any negative effects of biotechnological issues. Although half of the sample interviewed did not accept biotechnologies in general and GM foods in particular, there was rather high approval of some specific health and economic benefits. About 80 percent of the sample interviewed lack confidence in existing government regulatory systems probably due to inadequate capacity. Upgrading of the existing regulatory system with adequate capacity to regulate the ethical and moral issues associated with biotechnologies and GM foods was recommendedBiotechnology, Stakeholder, Acceptance, GM Foods

Acceptance of biotechnology and social-cultural implications in Ghana

Despite major scientific progress in the application of biotechnology in agriculture, public attitudes towards biotechnology in general and genetically modified food (GM food) products in particular remain mixed in Africa. Examining responses on acceptance of GM food through a stakeholder survey in Ghana, it was established that half of the 100 people sample interviewed were not in favor of GM foods. To this group acceptance of GM foods would make farmers loose focus on the traditional ways of cultivation, putting the whole nation at the mercy of profit driven foreign companies who produce GM foods. In order to have clear and unbiased attitudes towards agricultural biotechnology in Africa, there is the need to substitute dominant ideologies in the way biotechnology research and dissemination are conducted in developed countries with tailor-made methodologies in developing countries. This paper emphasizes the social dynamic force of food focusing on the need for social shaping of biotechnologies to reflect local and regional needs. Respondents’ perceptions of GM foods suggest that food is seen as not just a commodity to be consumed but food has both cultural and national identities. Generally, people are identified by their consumption and nutrition lifestyles and therefore take pride in what they eat. A proposal is made to set biotechnology research agenda in the context of social choices; social scientific coalition of biotechnology with endogenous development pathways’ as opposed to ‘exogenous biotechnology research’. Also there is the need for adequate capacity building of the existing regulatory institutions to handle ethical and moral issues associated with biotechnology research since survey findings showed lacked of public confidence in them.Biotechnology; survey; acceptability; social shaping; Ghana

The multifrequency behaviour of the recurrent nova RS Ophiuchi

This review concentrates on the multifrequency behaviour of RS Ophiuchi and in particular during its latest outburst. Confirmation of the 1945 outburst, bipolar outflows and its possible fate as a Type Ia Supernova are discussed.Comment: 5 pages, 5 figures, in The Golden Age of Cataclysmic Variables and Related Objects, F.

Global coverage of cetacean line-transect surveys : status quo, data gaps and future challenges

Knowledge of abundance, trends and distribution of cetacean populations is needed to inform marine conservation efforts, ecosystem models and spatial planning. We compiled a geo-spatial database of published data on cetacean abundance from dedicated visual line-transect surveys and encoded >1100 abundance estimates for 47 species from 430 surveys conducted worldwide from 1975-2005. Our subsequent analyses revealed large spatial, temporal and taxonomic variability and gaps in survey coverage. With the exception of Antarctic waters, survey coverage was biased toward the northern hemisphere, especially US and northern European waters. Overall, <25% of the world’s ocean surface was surveyed and only 6% had been covered frequently enough (≥ 5 times) to allow trend estimation. Almost half the global survey effort, defined as total area (km2) covered by all survey study areas across time, was concentrated in the Eastern Tropical Pacific (ETP). Neither the number of surveys conducted nor the survey effort had increased in recent years. Across species, an average of 10% of a species’ predicted range had been covered by at least one survey, but there was considerable variation among species. With the exception of three delphinid species, <1% of all species’ ranges had been covered frequently enough for trend analysis. We use a data-rich species, sperm whale, as an example to illustrate the challenges of using available data from line-transect surveys for the detection of trends or for spatial planning. Finally, we propose and contrast several field and analytical methods to fill in data gaps to improve future cetacean conservation management efforts.Publisher PDFPeer reviewe

New-New Trade Policy

When national competitiveness is invoked as a policy objective, trade experts have learned to retort that countries don`t trade, firms do. This focus on the importance of the firm in international trade is consistent with the most recent developments in trade theory, but policy needs to catch up. Recognizing the growing anomalies in observed trade patterns relative to traditional models of trade based on national comparative advantage, the "new trade theory" of the 1980s looked at industries not countries, leading Nobel prize-winner Paul Krugman, a pioneer in this literature, to suggest the need for a new trade policy. Recent work on what some call the "new-new trade theory" focuses on the trading behaviour of individual firms, making a tight link between trade and productivity. In this paper we demonstrate how focusing on firms should be the foundation for a new-new trade policy, one that creates exciting opportunities for trade and investment promotion strategies, along with the need for much more targeted consultation strategies. We also discuss the implications of the new-new theory for regulatory coordination, and on new ways to cooperate with interlocutors in developing countries on the evolution of 21st century trade policy.New-new Trade Theory, Trade Policy
