However, along with its growth none could envisage the growing socio-cultural and environmental problems associated with the development of this industry. Therefore, this book would give baseline knowledge about the present status of the industry and its impact on the local environment. A field survey in this regards was undertaken in this area, and qualitative analysis was done in terms of social structure, cultural variability, status of education, impact on bio-diversity, state of pollution and man wildlife conflicts. The analysis should help focus some light on the issues like social dynamics and environment protection a pathway for sustainability. This could specifically be of use to the students and budding researchers focussed to work on mountain environments accompanying social dynamics and sustainable development. ····· 10361132720

Lakes and their surrounding watersheds are unique and valuable ecosystems for both people and nature. Lakes are critical storage tanks for freshwater. Despite their importance, many of the world s lakes are in crisis. The main causes are inflow of domestic sewage, agricultural run-off, and discharge of industrial effluents, over-fishing, and introduction of exotic species and habitat degradation from population growth, expansion of cities. As more water is withdrawn for human use and more of it is returned to lakes and rivers badly polluted, there is less available to maintain vital freshwater ecosystems. Such activities have altered the physical, chemical and biological processes within aquatic ecosystems. These multiple threats have different histories, operate on different space-scales (catchment, local, regional and global) and involve different pathways of pollutant transfer (land, water, and atmosphere). ····· 10361132704

The study forecast the socio economic status of buffer zone households where deficit is mainly managed through remittance and wage labor. About 48.6% of the households faced food deficit and 15.7% did not have food even for a month, suggesting widespread poverty. Though forest area in Argayuli VDC increased by 12.71% between 1978 and 1992, buffer zone forest can only sustainably fulfill 32% of fuel wood and 0.9% of green fodder annually suggesting dependency on national forest and park. People extract 47.36% fuel wood and 16.03% fodder demand from buffer zone forest indicating over harvesting of resources. Rhinos were considered the most destructive animal in poverty stricken area as they damage crops all round the year, threatening their subsistence that made local people behave adversely on park and park management. Besides, invasive species, Mikania micrantha inside community forest indicated the wildlife habitat may get deteriorated. ····· 10361132703

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Deforestation rate in sub-Saharan Africa (SSA) surpassed the global annual average of 0.8 percent - twice the world rate. Socio-economic factors of mainly exponential population growth and high poverty rate are quite often held responsible for the growing deforestation rates in SSA. This link, however, ignores the impact of other important institutional factors on deforestation throughout Africa. Skewed institutional policies, for instance, largely contribute to the increased deforestation rate in most SSA countries. This in turn perpetuates a myriad of unhelpful practices including illegal logging, shifting cultivation that influence other socio-economic factors that eventually accelerate forest degradation. This book, therefore, provides a fresh approach of analyzing the direct or indirect link between land use and ultimately forest cover change in the SSA and its relation to institutional effectiveness. This is an empirical research that evaluates the role that inadequate institutional governance structures play in deforestation across SSA. ····· 10361132055

While the Eurasian Collared Dove preferred the open grass fields, the Red Collared Dove preferred both the grass and the cultivated fields. The Spotted Dove preferred the shady places near cover and scrub. The Laughing Dove preferred the grass field, area close to cover and the scrub. It was found that the different species of doves coexisted in the study area during the winter season, when the food was temporarily superabundant . While feeding together, the doves reduced the inter-specific competition by partitioning the available seed resource between them. The Eurasian Collared Dove was observed to feed more on Echinochloa colonum and Paspalidium flavidum, while the Red Collared Dove fed more on the seeds of Paspalum distichum and then on Echinochloa colonum. The Spotted Dove fed more on Paspalidium flavidum and then on Setaria verticillata and Brachiaria ramosa.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In Nepal, there are more than 6000 small to large rivers, which flow through diverse geography along pronounced altitudinal gradients. The river classification (stream typology) is mainly based on physical characteristics of basin such as source of origin availability of water and location, and aquatic biota (fishes). The stream typology based on physical characteristics is too general for their applicability in river management while based on biotic are without clear demarcation and lots of overlapping. However, none of these stream typologies is in use for river management. The classification of rivers in respect to environmental and biological variables can provide sound system for sustainable river management in Nepal. The stream order based river classification considers multiple environmental variables and biological factors that change from source to mouth. The present study has found that catchment characteristics, physico-chemical parameters and macroinvertebrate composition are closely related with stream order in Indrawati river. Thus, the study concludes that stream typology based on Strahler stream order is applicable to Indrawati river system, Nepal. ····· 10361131825

The Alder (Alnus subcordata C. A. Meyer) is a rare species sturdy and fast-growing belonging to the birch family (Betulaceae) and native to temperate area in North forests of Iran. As genus of Alder, the trees establish symbiosis with the nitrogen-fixing Actinobacteria. These bacteria convert atmospheric nitrogen into soil-soluble nitrates, which can be utilized by plants and favorably enhances the soil fertility. The fallen alder leaves make very rich compost, especially through mineralization of nitrogen leached from litter. The physiographic variables such as elevations, aspects and slopes had positive and negative significant relationship emerged as the effective factor on Alder growth. In worldwide there are many academic resources about Alder species except Alnus subcordata. In this book we attempt to explain the natural and plantation Alder stands and analyze the physiographic factors on growth of the trees. ····· 10361131779

This study was conducted in an area that does not seem to have any obvious disturbance that may favour resprouting. Thus the study investigated whether resprouting was a survival strategy in response to disturbance or a feature that was merely an expression of phylogenetic underpinnings of the plants. Furthermore, the study examined how trees that do not resprout survive in an area where a high proportion of trees resprouted. Finally, the implications of resprouting to performance of individuals and species in terms of resource allocation, water use, growth rate, stature, leaf traits, seed yield and size, seedling recruitment, population structure, species diversity and role in succession were investigated. ····· 10361119782

A determination and comparison of tree species composition and structure, regeneration potential and capacity, litter production and nutrient fluxes between disturbed and undisturbed sites is done. A socioeconomic appraisal of the inhabitants is outlined. Forest cover change analysis of the greater Mau forest for the period between 1984 and 2003 using Landsat satellite images is elaborated. The vertical stratification of the forest reserve depicts secondary growth in the reserve. The potential for natural regeneration of trees after natural or anthropogenic disturbance exists despite a poor soil seed bank. High litter annual turn over in disturbed sites, coupled with lower nutrient content and nutrient use efficiency as well as higher fine litter C: N and C: P ratios defines them as poorer sites. A chronological degradation in the condition of the forest over time is apparent with current land uses having negative significant effects.

Motorised boats run by diesel are the chief mode of transport across the river and creeks of Sundarbans mangrove. Occasional spillage of diesel from these vessels often contaminates the water and littoral habitat of mud whelk, an important molluscan resident of this estuary. Hemocytes, the chief immunoeffector cells of mollusc perform diverse physiological functions like nonself recognition, biological plug formation by aggregation, elicitation of cytotoxicity and phagocytosis. Undesirable shift in hemocyte density, nonself recognition ability and cytotoxicity in mud whelk exposed to diesel are indicative to impairment of immune status and reduction of survival fitness of this species in its natural habitat. Prolonged exposure and toxicity of diesel in benthic community may lead to a gradual loss of littoral biodiversity of Sundarbans estuary. ····· 10361119510
