O manguezal é considerado o ecossistema mais produtivo do planeta, tendo funções variadas, como a produção de nutrientes, estabilizador dos processos erosivos nos litorais, área de reprodução, abrigo e fuga de espécies, além de ser fundamental para o controle das alterações geradas pelas mudanças climáticas. No entanto, são áreas extremamente ameaçadas pelas atividades humanas. Nesse contexto, esta pesquisa objetiva avaliar as contribuições do manguezal do Rio Coreaú para a dinâmica socioambiental do município de Camocim, pois impactos sobre ele podem ter repercussão no que diz respeito aos processos tanto econômicos como ambientais. O Rio Coreaú, em Camocim, apresenta a segunda maior área de manguezal do estado, possuindo 35,3km², segundo a SEMACE (2004). Para o alcance do objetivo deste estudo foram realizados estudos bibliográficos e documental acerca da temática, avaliação de imagens de satélite da área e visitas in loco para levantamento das atividades econômicas associadas ao ecossistema.Palavras-chave: Estuário; Rio Coreaú; Relação socioambiental. RESUMEN El manglar se considera el ecosistema más productivo del planeta, tiene funciones variadas, como la producción de nutrientes, la estabilización de los procesos de erosión en la costa, el área de reproducción, el refugio y el escape de especies, además de ser fundamental para el control de los cambios generados por los cambios climáticos.

This paper analyzes the historical conditions of Yemen’s Sufi movement from the beginning of Islam up to the rise of the Rasulid dynasty in the thirteenth century. This is a very difficult task, given the lack of adequate sources and sufficient academic attention in both the East and theWest. Certainly, a few sentences about the subject can be found scattered in Sufi literature at large, but a respectable study of the period’s mysticism can hardly be found.1 Thus, I will focus on the major authorities who first contributed to the ascetic movement’s development, discuss why a major decline of intellectual activities occurred in many metropolises, and if the existing ascetic conditions were transformed into mystical tendencies during the ninth century due to the alleged impact ofDhu’n-Nun al-Misri (d. 860). This is followed by a brief discussion ofwhat contributed to the revival of the country’s intellectual and economic activities. After that, I will attempt to portray the status of the major ascetics and prominent mystics credited with spreading and diffusing the so-called Islamic saintly miracles (karamat). The trademark of both ascetics and mystics across the centuries, this feature became more prevalent fromthe beginning of the twelfth century onward. I will conclude with a brief note on the most three celebrated figures of Yemen’s religious and cultural history: Abu al-Ghayth ibn Jamil (d. 1253) and his rival Ahmad ibn `Alwan (d. 1266) from the mountainous area, andMuhammad ibn `Ali al-`Alawi, known as al-Faqih al-Muqaddam (d. 1256), from Hadramawt.

In recent years, accretion-erosion processes are frequently recorded in the estuary of Cua Dai, Quang Nam province. Most recently, however, sand bars are formed in the estuary not far from the place where the Inland Waterways Authority of Vietnam had previously dredged. The estuary continues to be accreted by sand. These have been drawing special attention of national and international scientists. While there is accretion at the estuary, eroded processes are strongly recorded along the coastlines of Quang Nam province. Therefore, it is necessary to carry out a study in the effects of the hydrodynamic regime on morphological changes in the Cua Dai estuary and coastlines of Quang Nam province. The goal of this paper is to fully interpret the causes, regimes of accretion and erosion processes over the study area. In this study, satellite images and hydrodynamic models of Delft3D and MIKE 11 are applied. The results show a strong accretion process in the estuary of Cua Dai. Sandbar formation across the Cua Dai estuary comes from the interaction of flood, wave, and current conditions during the northeast monsoon. This mainly affects the changes in morphology in the estuary of Cua Dai, Quang Nam.

Coastal erosion is the process of land erosion in coastal areas due to waves and ocean currents which reduce land and can adversely affect socio-economic activities in coastal areas. Coastal erosion risk assessment in the estuary is a development of previous research, because the erosion and accretion processes do not only occur along the shoreline, but also on the side facing river water bodies, due to the confluence of fluvial and marine processes. The landward shift of the shoreline in the Muara Asam Asam coastal area has reached 90 meters in the last 28 years, and has been detrimental because the area is a densely populated area with major economic activities in the fisheries and agriculture sectors. This study aims to determine the coastal erosion risk level zones based on the relationship among vulnerability and consequence parameters, through distance decay weighted based method. The results indicate that Muara Asam Asam has high risk zones of coastal erosion, especially in densely populated residential areas and dry land agriculture on the west side of the estuary, due to the lack of implementation of preventive measures through hard coastal structure and coastal zoning policy to protect socio-economic activities and coastal ecological environments.

 This paper presents the existing situation at national and world level considering the available water resources, their vulnerability especially in the mountains areas, the impact of climate changes, the possible conflicts regarding the intensification of water shortage in some regions of the world. I also present a case study on forests in Romania. Beginning with the general data mentioned above, we point out the specific peculiarities of the mountain area hydrology for identifying some aspects which are specific to the mountain water relationship. The analysis is necessary as no specifications regarding the mountain hilly or plain areas are done in the activity regarding waters management. Waters are managed unitary on river basins considering some general principles, unanimously recognized, well reflected into the national and international regulations. As a first stage, traditional economic activities are identified in the relationship of the mountain areas inhabitants with water but also some present approaches. The way the mountain areas inhabitants knew how to live together and capitalize water resources represents a model and impulse for coming back to such sustainable solutions but capitalizing the advantages of modern technologies. Each of these activities referring to waters which take place in the mountains area can represent ways for the research activity and future thorough studies from the technical, economic, social, cultural-traditional point of view and also for environment protection. A main preoccupation might have connection with the evolution of agricultural activities in the mountains area considering the climate changes and a possible “migration” towards higher areas of some agricultural practices specific to lower areas. The paper also shows a small example of the regaining by the locals of a community of an important resource for their lives in the hands of corporations: the forests defaced by HOLZINDUSTRIE SCHWEIGHOFER and stop flooding villages.

AbstractDrylands are ecosystems with limited water resources, often subjected to desertification. Conservation and restoration efforts towards these ecosystems depend on the interplay between ecological functioning and spatial patterns formed by local vegetation. Despite recent advances on the subject, an adequate description of phase transitions between the various vegetated phases remains an open issue. Here, we gather vegetation data of drylands from Southern Spain using satellite images. Our findings support three vegetated phases, separated by two distinct phase transitions, including a continuous phase transition, with new relations between scaling exponents of ecological variables. The phase diagram is obtained without a priori assumption about underlying ecological dynamics. We apply our analysis to a different dryland system in the Western United States and verify a compatible critical behavior, in agreement with the universality hypothesis.

We review the usefulness, limitations, significance, and coastal management implications of radionuclide measurements in Brazilian coastal environments. We focus on the use of radionuclides as tracers of sedimentary processes and submarine groundwater discharge (SGD). We also discuss artificial radionuclide contamination and high natural radioactivity areas. The interpretation of 14C-, 137Cs-, and 210Pb-derived sedimentation rates has provided evidence that inappropriate soil use by urban and agricultural activities has intensified erosion processes on land, which is reflected in depositional environments, such as coastal lagoons, estuaries and mangroves. Of the processes discussed in this paper, SGD is the one that requires the most scientific effort in the short-term. There have been only two case studies using 222Rn and radium isotopes as groundwater tracers in Brazil. These investigations showed that SGD can be a major source of nutrients and other dissolved species to the coastal ocean. Baseline 137Cs, 90Sr, 239+240Pu, and 238Pu concentrations in seawater from the whole Brazilian coastal zone are very low. Therefore, in spite of contamination problems in many ecosystems in the northern hemisphere, artificial radionuclide pollution appears to be negligible along the Brazilian coast. Phosphate fertilizer industries and petroleum processing facilities are the main economic activities producing Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM). Even though a few attempts have been made to assess the radiological effects of these activities, their potential threats indicate a need for the radiological control of their wastes. This review showed that the number of studies within the field of environmental radioactivity is still small in Brazil and much more research is needed to understand processes of high interest for environmental managers. In the near future, it is likely that such studies in Brazil will move from descriptive, environmental quality-based assessments to approaches that attempt to quantify chemical, physical, and biological processes in the environment.

The English lawyer has been notoriously unwilling to admit the relevance of social sciences to his discipline. In part, this may be attributed to his lack of formal training in economics or sociology. As regards the latter, there are some signs of the handicap being overcome: much current research effort is now being directed to the interpretation of law and the legal system as social phenomena. But the application of economic reasoning to legal instruments and institutions has been limited and tentative. Although it has long been recognised that a marriage of the two disciplines is necessary for the procreation of effective norms in areas where the law clearly governs economic activities, for example, the regulation of trade and income redistribution, so far, in this country at least, creative thinking about central legal institutions such as tort, contract, property and crime has remained relatively untouched by such a mode of analysis. Yet, as Americans have demonstrated, there is nothing inappropriate in such an exercise. At first sight the subject areas of economics and law will appear to diverge significantly: the former is “concerned with the manner in which a society produces, distributes and consumes wealth when it is constrained by scarcity, either of tangible resources or of intangible resources,” while the latter is often viewed as a system of norms governing the conduct of individuals and institutions. Yet such conduct will generally involve the transfer and acquisition of resources. With this congruence of interest, therefore, the opportunity exists to compare economic analysis with prevailing legal rules on particular issues to see whether the “right” solution is reached.
