Abstract: Municipal Solid Waste (MSW) describes the stream of solid waste generated by households, commercial establishments, industries and institutions. Improper disposal of MSW has serious repercussions for the environment and human health. One of the serious problems is ground water contamination. Asian countries are facing municipal solid waste management problems due to the rapid growth in solid waste generation rate and open dumping practices. As water percolates through MSW, it makes leachate that consists of decomposing organic matter combined with iron, mercury, lead, zinc and other metal, which is the cause for the Groundwater contamination in the nearby areas of the dumpsite. So there is a need for Groundwater analysis around the dumpsite to know to what extent Groundwater has been contaminated. The present work aims to analyze the Groundwater contamination by collecting the Groundwater samples from the residential area near the dumpsite

Abstract: Locating a landfill site in cities of Developing nations have been recognized as a significant physical planning problem and is receiving much attention from researchers in planning sector. A suitable disposal site must have environmental safety criteria and attributes that enable the wastes to be isolated at no risk to people or the environment. Criteria for site selection include; natural physical characteristics, socio-economic, ecological and landuse factors. Different tools and techniques have been developed for solid waste disposal site selection in Developing Countries. This paper examines the selection of waste disposal sites using Geographical Information System in Akure, Nigeria. Landsat Enhanced Thematic Mapper plus (ETM+) 2002 and Shuttle Radar Topographic Mission (SRTM) 2011 were used to map the most suitable site for waste disposal in Akure. The result indicates that sites were found within the study area. The most suitable sites in the study area are located at 750m to surface water and 300m to major and minor roads, which ensure that economic costs of implementation are mutual. The selected areas have slopes less than 12%, with infrastructural advantage and minimizing environmental impacts. The study proposes acceptable landfill sites for solid waste disposal in the city.

Abstract: The paper is an attempt to identify the importance of bird watching as a determinant of environmental health. To critically understand the eco-health of the habitat, the trend of arrival, food and habitat of bird population in Kulik Wildlife Sanctuary of West Bengal have been analyzed and results indicate that flood in the river Kulik very adjacent to that sanctuary is the foremost cause of decline in the arrival of certain species. Apart from the flood, the changing climate, deforestation and anthropogenic factors are also probable factors responsible for such decline. Therefore, such analysis or approach of study does not only reveal the spatio-temporal conditions of the concerned habitat but also signify the state of that habitat- whether it is lowering down or stable or recuperating.

Abstract: Ever since their evolution, forests have been interacting with the Earth's climate. Deforestation and forest degradation in many countries has lead to forest fragmentation with effects on increasingly insularized and vulnerable forest habitat patches. If forest fragments are becoming too small to support important keystone species, further extinctions may occur in cascading ways and the vegetation structure and composition may eventually collapse. Until now relatively few reported cases of species extinctions can be directly attributed to climate change. However, climate change in combination with habitat destruction, degradation, and fragmentation may lead to new waves of species extinctions in the near future as species are set on the move but are unable to reach cooler refuges due to altered, obstructing landscapes. To mitigate the future risks of extinctions as well as climate change, major efforts should be undertaken to protect intact large areas of forests and restore wildlife corridors.
