| Scientific programming in environmental science often relies on short-term (3 to 5 years) trend-based projections for contextual elements like the demography or the economy to construct or justify its choice of priorities. However, this approach does not take into account numerous factors of change or disruption over a longer term (10 to 20, or even 50 years), although a decade or two are needed to effectively deal with the stakes of research. These stakes become more acute over the long term, as consequences of predicted changes (e. g. climate) or other factors such as pollution, biodiversity erosion, reduction of ecosystemic services.... This complex question justifies turning to a foresight approach. Because it enables tipping points to be envisaged for... |

| In French Polynesia, the aquaculture of P. margaritifera is carried out in numerous grow-out sites, located over three archipelagos (Gambier, Society and Tuamotu). To evaluate the impact of macro-geographical effects of these growing sites on pearl quality traits, five hatcheries produced families were used as homogeneous donor oysters in an experimental graft. The molluscs were then reared in two commercial locations: Tahaa island (Society) and Rangiroa atoll (Tuamotu). At harvest, eight pearl quality traits were recorded and compared: surface defects, lustre, grade, circles, shape categories, darkness level, body and secondary colour and visual colour categories. Overall inter-site comparison revealed that: 1) all traits were affected by grow-out... |

| The relative sensitivities of 309 common invertebrate species in Dutch marine waters are presented for environmental and anthropogenic pressures like organic enrichment, sedimentation and fisheries. The species were furthermore appointed to trophic groups like suspension and deposit feeders. The Dutch Ministry of Infrastructure and the Environment uses these data when calculating the Benthic Ecosystem Quality Index 2 and the Infaunal Trophic Index. These metrics aid in the mandatory monitoring of ecological quality for example for the European Water Framework Directive. The common Dutch species were selected based on their abundance according to, 1. the mwtl dataset including results of on-going monitoring programs issued by the Ministry, 2. the... |

| ABSTRACT Fish reproduction in floodplain rivers is often linked to flow regime and with the inundation of floodplain habitats. However, in confined rivers, where floodplains are absent, the relation between reproduction and flow can in comparison be expected to be distinct. In this study, we describe the reproductive life-history of Hemiancistrus fuliginosus and Hypostomus isbrueckeri in a confined river and discuss its differences relative to floodplain loricariids and also the implications for effects of dam construction and flow regulation. We found the reproductive peak of both species occurred during lowering waters, just after maximum river flow, in contrast to floodplain species that tend to spawn during rising waters. The studied species presented... |

| While industrial growth is mainly a function of market forces, governments actively pursue policies and activities to accelerate industrialization. These policies, directly or indirectly, affect the natural environment. Sound industrial and environmental policies are not incompatible, even though it is difficult task either to set and enforce at the same time environmental standard that do not have some negative impact on industrial development options, or to formulate industrial policies that take environmental issues fully into account. The objective of this study is to elaborate a national assessment for the purpose of the industrial environment overview in the process of sustainable development in Côte d’Ivoire which is a part of the systematic... |

| The seasonal changes of heat and salt storages in the offshore water of the Red Sea were studied using a historical data collected from different cruises during the period from 1924 to 1998. The heat storage within water column of different depths exhibits a seasonal variability. The heat storage is low during winter and high during summer. Also, the heat storage increases from north to south. The maximum values of heat storage are found in the southern central part of the Red Sea. It reached about 29.9x109 J/m2 within the water column of 300m depth. The seasonal change of heat storage from the annual mean is negative during winter and spring, while it is positive during summer and autumn. It has higher values during winter and summer, while its value... |

| Challenges the fishing ports of Ghana, notably Sekondi Port include the congestion and the deteriorating efficiency due to the increase of users and decreasing quality of catch due to the shortage and ageing of landing facilities, fish handling sheds and ice-making facilities. The Government of Ghana made a request to Japan for an extension of the wharf, construction of additional breakwater, cold storage and ice-making facility at Sekondi Fishing Port in 2010 in order to overcome these challenges. In response the Government of Japan conducted a survey for the project to promote efficiency and improvement of Ghana's fishery sector. The survey was to examine the need, relevance and urgency of the proposed project. |

| The stranding of sperm whales at the Belgian coast in November 1994 attracted the general attention of the media. Excessive shows of passion often encountered in other parts of the world when cetaceans die, were not observed. An examination of the articles which appeared in the press shows that the event was merely treated as a major, but common news item. Priority was given to the daily developments. The work of the authorities and that of the scientists were given similar status as the anecdotic aspects. The importance given to controversies regarding the management of the situation must be stressed. The media did not go deeply into the biology of sperm whales, the stranding that occurred abroad, or the various hypotheses that were discussed. How could... |
