Scenario analysis is a useful tool for exploring key uncertainties that may shape the future of social-ecological systems. This paper explores the methods, costs, and benefits of developing and linking scenarios of social-ecological systems across multiple spatial scales. Drawing largely on experiences in the Millennium Ecosystem Assessment, we suggest that the desired degree of cross-scale linkage depends on the primary aim of the scenario exercise. Loosely linked multiscale scenarios appear more appropriate when the primary aim is to engage in exploratory dialog with stakeholders. Tightly coupled cross-scale scenarios seem to work best when the main objective is to further our understanding of cross-scale interactions or to assess trade-offs between...

Measuring the biological impact of drilling waste on the deep seafloor: an experimental challenge
Provedor de dados: 5
Autores: Lelchat, F.; Dussauze, M.; Lemaire, P; Theron, M.; Toffin, Laurent; Le Floch, Stephane.
The depletion of traditional oil fields is driving the oil &amp; gas industry to explore new exploitation sites previously considered as unprofitable. Deep-sea oil fields represent one of these new areas of exploitation. Well drilling during exploration and production operations generate large quantities of drilling waste whose biological impact on the deep-sea floor remains largely unknown. Because of the harsh abiotic factors characterizing this environment, the evaluation of this impact remains challenging. High hydrostatic pressure is the prominent factor which will affect in-situ biological processes. This review will examine the feedback on the various strategies used to evaluate the biological impact of deep-sea drilling waste deposition as well as...

Autores: Buss,Daniel F.; Borges,Erika L.
This study is part of the effort to test and to establish Rapid Bioassessment Protocols (RBP) using benthic macroinvertebrates as indicators of the water quality of wadeable streams in south-east Brazil. We compared the cost-effectiveness of sampling devices frequently used in RBPs, Surber and Kick-net samplers, and of three mesh sizes (125, 250 and 500 µm). A total of 126,815 benthic macroinvertebrates were collected, representing 57 families. Samples collected with Kick method had significantly higher richness and BMWP scores in relation to Surber, but no significant increase in the effort, measured by the necessary time to process samples. No significant differences were found between samplers considering the cost/effectiveness ratio. Considering mesh...

consumption needs of the population, it remains difficult to assure the continuity of national resources or to provide for protection of nature. The Convention of Biological Diversity has identified the need for Parties to integrate biodiversity with other sectors of the economy and civil society. Given that EIA is the only instrument available to ensure that consideration is accorded to environmental aspects in economic development plans, it is important that EIA should fully incorporate biodiversity considerations, to ensure that natural resources are taken into account in the development process.

Autores: Hénocque, Y.; Denis, J.
This second volume of a guide to integrated coastal zone management opens a new dimension by discussing the processes involved in a more complete and dynamic way than the first, To fulfil1 this requirement, an expanded work group, drawing upon the knowledge of experts in political science, economics, and sociology, devoted over two years of effort (1999 - 2001) to its completion, following a disciplined working method. A dual principle prevailed in the application of this method. On one hand, it prescribed an approach structured as a series of steps, and on the other, it demanded that real situations be brought to light, emphasizing case studies of experience with or analysis of coastal management.

Composite Guidelines for the Environmental Assessment of Coastal Aquaculture Development. Vol. 2 : Appendices
Provedor de dados: 20
Autores: Shivappa, R.B.; Chowdhury, M.A.K.; Phillips, M.; Hambrey, J.
The farming of seaweed (Euchema spp.) began in the late 80’s, stimulated by government promotion and the active involvement of international corporations in promoting small-scale production. The industry grew rapidly in the early 90’s reaching 4,000 tonnes in 1995, but has since declined, related partly to marketing difficulties. There has been significant interest in shrimp farming for several years. Tanzania has good international trade routes, suitable climate, and a long coastline well suited to brackish-water pond production. To date the main interest has been in medium to large-scale projects with significant foreign interests. Environmental assessments have been carried out in respect of at least two proposed shrimp farm developments. The procedures...

Autores: Figueira, M.; Tarr, P.
Namibia is the last African country to have gained independence from colonial rule. It has inherited a weak, skewed, resource-based economy and an administrative and regulatory framework that reflects a colonialist approach to management and planning. A century of unsustainable practice has resulted in environmental degradation and opportunity costs. The challenges facing the current generation include democratising decision making, protecting the country's fragile ecosystems, and institutionalising an approach towards planning that promotes sustainable development. It is widely recognised that environmental assessment is a useful planning tool in promoting sustainable development. Namibia's first post-colonial government has embarked upon an ambitious...

Meiobenthos as a tool in the assessment of marine environmental quality
Provedor de dados: 27
Autores: Heip, C.H.R.
The assessment of the impact of pollution on the marine environment depends on the possibility of prediction either by comparison or more ideally by the analysis of time series which are long enough. Obtaining data for the construction of these time series should be one of the principal goals of monitoring. Parameters which are measured should have a low variability in time and in space or low frequency. The analysis of meiobenthic communities in the North Sea and the adjacent estuaries shows that harpacticoid copepods are especially suitable as the number and the nature of the species are stable and density, biomass, and diversity are characterized by the absence of variance in the high frequencies. Nematodes, though overwhelmingly abundant, are more...
