One third of the world’s population lives in coastal areas and rapid development of these areas has meant increased construction of coastal infrastruc- ture (e.g. ports, navigation channels, coastal de- fence) and related activities (e.g. land reclamation, beach nourishment), which has inevitably led to conflicting priorities between coral reef conservation and economic growth. The key impacts of these ac- tivities, if not managed, include:
• Direct loss of coral reef caused by the removal or burial of reefs
• Lethal or sub-lethal stress to corals caused by elevated turbidity and sedimentation rates
Dredging and port construction activities potentially affect not only the site itself, but also surrounding ar- eas, through a large number of impact vectors (e.g. turbid plumes, sedimentation, release of contami- nants, bathymetric changes). Effects may be imme- diate or develop over a longer timeframe and may be temporary or permanent in nature, depending on a large number of factors.
The threat posed to coral reefs by biological invasion is unlikely to diminish and should therefore be considered in analyses of the effectiveness of Marine Protected Areas.Resource Type: Journal Papers
Protected areas can act as a case study for REDD: lessons can be learnt from their success or otherwise in reducing deforestation and supporting local livelihoods. Further research into the most effective management and governance frameworks for acheiving goals on carbon emissions, biodiversity and communities, and the extent to which protected areas reduce (or merely displace) deforestation within national boundaries would be useful in informing REDD implementation.Resource Type: Journal Papers
Recent CITES decisions that accepted an obligation to take into account the impacts of CITES listings on the livelihoods of the poor, have some affinities with the ‘Do no harm’ approach to the livelihoods of the poor. The process will produce guidelines and rapid assessment tools. If these guidelines and tools are to be effective they will need to take account of the context-specific nature of solutions in this area. The CITES case provides lessons for other international conservation institutions whose activities affect the livelihoods of the poor at the local level.Resource Type: Journal Papers
Here we describe a method for standardizing the collection and analysis of stories of change that originated in, and is commonly employed by, the development sector. Trials of the use of the Most Significant Change method in a range of Fauna & Flora International's partnership projects revealed not only its value as a monitoring tool alongside more familiar surveys and quantitative data collection but also as a participatory management tool that improved staff capacity and project adaptive management and responsiveness.Resource Type: Journal Papers
Global and regional coral reef area statistics are of considerable value in fields ranging from global environmental change to fisheries to conservation. Although widely quoted, Smith's 1978 figure of 600 000rkm2 is only an approximate calculation. The World Conservation Monitoring Centre has prepared a new estimate of reef coverage by mapping emergent reef crest and very shallow reef systems. These data were rasterised, using 1rkm grid squares, as a means of reducing errors arising from variation in scale. Global and regional reef coverages were calculated from the resultant grid. The total global area is estimated at 255 000rkm2, considerably lower than many previous estimates. Variation in reef area estimates is, in part, a function of variation in reef definition.Resource Type: Journal Papers
This report presents a synthesis and integration of the findings concerning biodiversity contained in the reports of the four Millennium Assessment Working Groups (Condition and Trends, Scenarios, Responses, and Sub-global Assessments).Resource Type: Reports
The countries affected by the 2004 Asian tsunami contain the most diverse and extensive coral reefs and mangroves of the Indian Ocean, and some of the richest in the world. Not only are these ecosystems among the most threatened in the world, they also provide numerous essential ecosystem services.
It is thus not surprising that reefs and mangroves received widespread attention after the tsunami, with three principal questions posed: Are the tsunami's impacts on reefs and mangroves a further threat to their future survival? Did reefs and mangroves play a role in shoreline protection and reduce structural damage and human mortality? How could reconstruction efforts include actions to maintain these ecosystems and reduce further threats to them?Resource Type: Journal Papers
Although trade in non-timber forest products (NTFPs) has been widely promoted as an approach to rural development, recent research has indicated that NTFP commercialisation is often not successful. Analysis of the factors influencing success of NTFP commercialisation has been hindered by the lack of an appropriate analytical approach for comparison of case studies. We tested and further developed a methodology recently developed by CIFOR, by examining 16 NTFP case studies in two workshops held in Mexico and Bolivia involving a variety of stakeholders involved in NTFP commercialisation.Resource Type: Journal Papers
Coral reefs are the most biologically diverse of shallow water marine ecosystems but are being degraded worldwide by human activities and climate warming. Analyses of the geographic ranges of 3235 species of reef fish, corals, snails, and lobsters revealed that between 7.2 and 53.6 of each taxon have highly restricted ranges, rendering them vulnerable to extinction. Restricted-range species are clustered into centers of endemism, like those described for terrestrial taxa. The 10 richest centers of endemism cover 15.8 of the world's coral reefs (0.012 of the oceans) but include between 44.8 and 54.2 of the restricted-range species. Many occur in regions where reefs are being severely affected by people, potentially leading to numerous extinctions. Threatened centers of endemism are major biodiversity hotspots, and conservation efforts targeted toward them could help avert the loss of tropical reef biodiversity.Resource Type: Journal Papers
