| Los vertidos de aguas residuales domésticas a las aguas marinas sin tratamiento apropiado constituyen una fuente importante de contaminación a la Región del Gran Caribe (RGC) y representa una amenaza para el desarrollo sostenible. El trabajo muestra un Estudio de Línea Base sobre el manejo de las aguas residuales domésticas en ecosistemas marino-costeros contaminados hot spots de Colombia (Bahía de Cartagena), Jamaica (Bahía de Kingston), Nicaragua (Bahía de Bluefields), Trinidad y Tobago (Golfo de Paria), Venezuela (Golfo de Cariaco), Guyana (Georgetown) y Suriname (Paramaribo) con un predominio de tanques sépticos, seguido del uso de letrinas y el alcantarillado sanitario, y se elaboran las bases para el diseño y planificación de planes de manejo... |

| Coastal resource utilization and management systems, bothtraditional and more recently conceived, were studied in Mecufidistrict, northern Mozambique in a post-conflict situation prior towhich a significant migration of people to the coast had occurred.A wide variety of coastal biotopes containing a multitude ofresources had been affected in various ways. Intertidalorganisms exhibited signs of decreasing abundance and averagesize, whereas offshore fishes and mangrove forests did not showsigns of overutilization. It was observed that traditional coastalmanagement systems were still influential, but that newerinitiatives were only beginning to enter into significant dialogueand cooperation with these. In the current circumstances ofpeace and political... |

| Le terme mangrove se réfère habituellement à un complexe de zones humides influencé par les marées et constitué de forêts marécageuses et autres habitats associés dans la zone intertidale sous les latitudes tropicales et subtropicales. Les écosystèmes forestiers de mangrove subissent des dégradations anthropiques de toutes sortes et de diverses amplitudes. La pression démographique provoque leur destruction et son influence s’accentue dans des zones non protégées, surtout au voisinage des agglomérations où les problèmes fonciers et la pauvreté poussent les populations à occuper des espaces libres à faibles coûts. Dans sa volonté d’assurer une gestion durable et participative des mangroves au Cameroun, le Gouvernement à travers le Ministère de... |

| The ecological quality ofthe Scheldt has been strongly affected by deepening, reclaiming and polluting the water of the river. The use of national instruments of protection has unsufficiently contributed to the recovery of the estuarium. Field managers of nature-areas have succesfully taken the negative effects of the other functions as starting point into their management. The program for compensation of lost nature on behalf of the recent deepening will be evaluated next year, and adapted if necessary. The European directives for nature, water and fishery become more and more important. They play a big role in the long term vision for the Scheldt-estuarium. |

| Researchers have estimated the total economic value of global ecosystem goods and services showing that a significant portion of humanity's economic well being is unaccounted for in conventional GNP accounting (Constanza et al., 1997). To demonstrate this point, authors have conventionally used highly aggregated landscape units for analysis (e.g., biomes), and average, not marginal values, of each ecosystem good or service are estimated for each unit using value transfer methodologies (Wilson et al., 2004). For example, Patterson and Cole (1999a, b) replicated the Constanza et al., (1997) approach by estimating economic values for Waikato and New Zealand ecosystem goods and services associated with standard land cover classes including horticulture,... |

| The definition of conservation goals is a complex task, which involves both ecological sciences and social values. A brief history of conservation strategies in Germany (protection of cultural landscapes), United States (wilderness ideal), and southern Chile (preservation paradigm and the more recent interest in ecotourism) illustrates a broad range of conservation goals. To encompass such an array of conservation dimensions and goals, the ecosystem approach adopted by the Conference of the Parties of the Convention on Biological Diversity represents a good approach. However, to become effective, this kind of approach requires clarifying and agreeing upon basic concepts, such as ecosystem. To serve that purpose, we present a scheme that considers the... |

| Soil quality has become an important issue in soil science. Considerable attempts have been made to define soil quality, but a general concept has not yet been accepted by the scientific community. The selection of quantitative indices for soil quality is extremely difficult, and a considerable number of chemical, physical, and biochemical properties have been suggested as potential indicators of soil quality. Because soil organic matter (SOM) can be associated with different soil chemical, physical and biological processes, it has been widely considered as one of the best soil quality indicator. Land use can significantly influence dynamics of organic carbon and N, P, and S cycle. However, changes in total soil organic carbon (SOC) contents in response to... |

| Abstract: Invasive species need a closer look on the threats they may cause to the environment, mainly considering the scenario of climatic changes predicted for the next decades. Schinus molle is a pioneer tree native from South America, reported as an important invasive species in four continents. Using ecological niche modeling we show that a wide area over the world is propitious for S. molle establishment under current climatic conditions, including 14 of the 25 world’s biodiversity hotspots. Current projections of climate changes suggest scenarios implying the rise of areas favorable for S. molle expansion. Therefore, particular attention should be taken in regions where it was introduced, while approaches for long-term intervention may be necessary... |
