It has cultural and religious meaning that united a paradigm of life. Two contradictive mainstreams are transcendental representing Islamic value and naturalistic representing cultural value lives in harmony and balance. This mutual accommodation had completed each other that produce certain Islamic practices. It also enriches the Islamic pluralism that admits various interpretation and understanding. The research results showed the religious practice that is broken down from Islamic values could not separate from natural resources management practices and praxis. The culture-religious practices orient to face nature uncertainty has an influence to communality of community. Sustainability of natural resources depends on the capacity of community to sustain their culture-religious-ecological practices and praxis. ····· 1036191267

El delfín nariz de botella es uno de los mamíferos marinos con la distribución más amplia. Estos organismos están distribuidos a lo largo de aguas costeras tropicales hasta las zonas templadas. Así mismo, es una de las especies más abundantes de cetáceos. Por tal motivo, analizar la distribución y abundancia de esta especie sirve para determinar su tamaño poblacional, su ubicación geográfica y su hábitat. Para esta investigación se empleó la metodología de muestreo a distancia para calcular el tamaño poblacional y se aplicó la técnica de foto-identificación para estudiar los movimientos y la residencia de los delfines. Para la zona de Veracruz las toninas se distribuyen en casi toda la zona costera, desde un individuo hasta grupos con 50 individuos. Se estimó una abundancia de 2,632 organismos tan solo para la zona norte del estado. Los estudios de una determinada área permiten evaluar el estado poblacional de estos organismos en la zona de estudio, es decir, si están en peligro de extinción o son ecológicamente estables. ····· 1036191230

Para el caso de los bosques tropicales no existe información suficiente sobre los cambios en la dinámica de la biomasa bajo diferentes regímenes de manejo. Se analiza aquí cómo la extracción selectiva de maderas influye en la dinámica temporal de acumulación de biomasa aérea y almacenamiento de carbono en un bosque húmedo de la Reserva Forestal Imataca, Venezuela, sometido a aprovechamiento forestal convencional.Los resultados obtenidos indican que, inmediatamente luego de la intervención ocurre una reducción de aproximadamente 50% en la biomasa aérea del bosque, expresado en una diferencia neta de alrededor de 162,87 Mg/ha. A través de la mejora en la planificación del aprovechamiento que implique, entre otras cosas, la adopción de técnicas de impacto reducido y un programa de monitoreo se podría reducir considerablemente la pérdida de biomasa e incidir en una recuperación más rápida del ecosistema. ····· 1036189475

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Salinity is one of the most severe environmental factors limiting the productivity of agricultural crops. The continuous loss of arable land due over-exploitation and mismanagement contribute to increase in salinity. Secondary salinization of agricultural lands is particularly widespread in arid and semi-arid environment where crop production requires irrigation schemes. At least 20% of all irrigated lands are salt affected with some estimates being as high as 50% whereas the world`s population continues to rise, the total land area under irrigation appears to have levelled off. Salinity is a major threat to irrigated agriculture because many of the soils and irrigation waters contain significant amount of dissolved salts. Due to excessive evapotranspiration in arid and semi-arid regions, the secondary salinization is becoming important factor for salinity. Most crops are sensitive to salinity caused by high concentration of salts in the soil. The book provides deep insight into saline soils and their influence on plant growth. Book is recommneded for researchers, students of University Department of Botany, Agriculture, Soil Science and Libraries alike. ····· 1036189037

It identifies the constraints to effective implementation of Nigeria s environmental laws and policies especially the Environmental Impact Assessment (EIA) as it concerns oil prospecting, which has hitherto contributed in hindering her environmental sustainability. It also unveils the critical issues concerning the deplorable state of the economy of the local populace of the region. After identifying the various problems contributing to the environmental woes, and the poor economic growth of the region, this research proffers recommendations that should be conscientiously and vigorously implemented to reverse the trend. Although, the oil companies have made some efforts towards providing the necessary infrastructures needed in the region, they need to do more in the area of capacity building, and use of green technologies to ensure healthy environment of their host communities. ····· 1036188546

The lack of a clear identity, definition of core competencies, and prescriptions for interdisciplinary pedagogy can create confusion among program stakeholders and skepticism among institutional administrators. To address these concerns, the National Council for Science and the Environmental sponsored a comprehensive national study to learn more about IE program curricula and investigate the potential for reaching agreement on core competencies. The results demonstrate that a consensus exists on the identity on the environmental studies field: an applied, interdisciplinary focus on the interface of coupled human-natural systems with a normative commitment to sustainability. The results also reveal that interdisciplinary core competency areas consist of three broad knowledge areas and two skill sets, and that three ideal curricular models for IE education are preferred by interdisciplinary environmental program administrators: systems science, policy and governance, and adaptive management. ····· 1036188497

The particles in this particular size regime display characteristic physical, chemical and optoelectronic properties, which are strikingly different from those of the corresponding bulk materials. Recently, physicists and chemists are interested in the electronic structure of metal and semiconductor nanoparticles because of the quantum size effect, which has been shown to appear in that size range. As the size of a material is reduced down to nanoscale dimension, the electronic structure of the material changes from continuous energy bands of the bulk state to discrete energy levels of the atoms. This book tells us the wet chemical route for the synthesis of well ordered aggregates of metal nanoparticles of variable sizes using different ligand. The effect of nanoparticle size on the nature of aggregation as well as the variation in the optical response due to variable degree of interparticle coupling effects amongst the gold particles have been investigated. ····· 1036187724

This thesis treads through the intricacies of the processes through which multilevel partnerships (MLPs) have been formed to produce and maintain gorilla tourism in Uganda s Bwindi Impenetrable National Park (BINP). The research focuses on two case studies (BCRC a community tourism enterprise and CMGL-a private-community partnership tourism enterprise) to analyse the extent to which tourism contributes to livelihoods. The research undertakes this task by combing Actor Network Theory s process of translation and the sustainable livelihood approach as a methodological point of entry.

The quality of water treated at the headwork before distribution and its quality in selected households were assessed. In all, one hundred and thirty-five (135) samples from twenty-seven (27) sites at the headwork and selected households were investigated. One hundred and twenty (120) samples of stored water from storage facilities in selected households in the study area were also investigated. The quality of water from the headwork, in terms of physico-chemical and bacteriological characteristics was generally good (WHO and EPA standards). The physico-chemical quality of tap water in the Districts was good,however, total coliform bacteria (0-120cfu/100ml) were detected in about three quarters of tap water sampled while faecal coliforms(0-10cfu/100ml) were detected in about a quarter. Frequent breaks in pipe lines resulted in water leakages, which also served as conduits for contaminant transport into the distribution system.Such contamination could also be enhanced through incidence of negative water pressure from water rationing. ····· 1036187559
