A avaliação ambiental estratégica como ferramenta ao planejamento e à gestão do território

Planned to be a process of early evaluation of Politics, Plans and Programs (PPPs), which interfere in the environment; the Strategic Environmental Assessment (SEA) suggests a methodology for planning and managing the land, which overcomes the limitations of the traditional plans that try to mitigate the environmental impacts of Projects, assuming a pro-active conception that incorporates the social and environmental aspects in the planning stage of the PPPs. This kind of Evaluation surpasses the existing limitations of the Environmental Impact Assessment (EIA), once the EIA happens after the planning process, when lots of decisions have been made and carried out. In order to overcome the limitations of EIA, the SEA is a strategic tool in the process of planning and managing the land. When we focus on the PPPs and not on the Projects, the SEA, which is more political than technical, priorizes the strategies that assure the integration of the environmental, social, economic and institutional aspects into the planning process, in private or public organizations. In this context, this work aims to establish the concept basis of the Strategic Environmental Evaluation as a tool for land planning and managing. The methodology procedures used here lie in the literature review concerning the SEA, analyzing how this tool can be introduced as an alternative for sustainable development. Although the SEA is a tool that introduces the sustainable development theme as a guiding principle of planning, it is seldom used by managers and decision makers, locally and nationally

Food composition of beryx-alfonsino over submarine rises near Azores

Qualitative and quantitative food composition, as well as intensity of feeding of beryx-alfonsino Beryx splendens was examined on banks near the Azores. Data are presented with respect to size groups and taking into account type of feeding of males and females. Crustaceans and fishes were constituents of their feeding ration. A tendency toward increase in the number of consumed fishes in the course of ontogenetic development of beryx-alfonsino was noted. Beryx-alfonsino was shown to occupy the trophic level of consumers of the third order performing function of a deep-water predator.

Palynological records from the Congo fan reveal environmental change in equatorial Africa occurring 1.05 Ma ago, 100 k.y. before the mid-Pleistocene climatic shift at 0.9 Ma. Prior to 1.05 Ma, a glacial-interglacial rhythm is not obvious in the African vegetation variation. Afterwards, Podocarpus spread in the mountains of central Africa mainly during glacials and Congo River discharge decreased. The sequence of vegetation variation associated with the mid-Pleistocene glacials and interglacials differed from that observed during the late Pleistocene. Between 0.9 and 0.6 Ma, interglacials were characterized by warm dry conditions and glacials were characterized by cool humid conditions, while during the past 0.2 Ma glacials were cold and dry and interglacials warm and humid. Our data indicate that before the Northern Hemisphere ice caps dramatically increased in size (0.9-0.6 Ma), low-latitude climate forcing and response in the tropics played an important role in the initiation of 100 k.y. ice-age cycles. During the mid to late Pleistocene, however, the climate conditions in the tropics were increasingly influenced by the glacial-interglacial variations of continental ice sheets.
