Nigeria is richly endowed with both coastal and inland wetlands, many of which are being threatened by anthropogenic drivers such as land use activities, urbanization, agricultural activities in addition to the emerging threats of climate change. Therefore, this study highlights the environmental assessment of urbanization land-use impacts on degradation of Eleyele Wetland in Ibadan SW-Nigeria....

Overwhelming evidence reveals that concentrations of dissolved organic carbon (DOC) have increased in streams which brings negative environmental impacts. DOC in stream flow is mainly originated from soil-water solutions of watershed. Wetlands prove to be the most sensitive areas as an important DOC reserve between terrestrial and fluvial biogeosystems. This reported study was focused on the di...

Background: Evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. Methods: In this study, total an...

The National Park of Las Tablas de Daimiel in Central Spain is a wetland area of great value regarding biodiversity and wildlife habitat. This type of ecosystem is unique within a semi-arid climate and especially sensitive to degradation processes caused by growing pressure on natural resources (agricultural practices, groundwater depletion and land use change) as well as climatic changes. The ...

This study aims to evaluate the non-market values of ecosystem services generated by wetlands in Southern Quebec. To accomplish this, we evaluated the value of wetland services related to 1) habitat for biodiversity, 2) flood control, 3) water quality and 4) climate regulation. Two non-market valuation methods are proposed, contingent valuation (CV) and choice experiment (CE). Our study aims to...

[1] Workshops to identify transboundary and basin-wide environmental issues and a diagnostic study by consultants identified priority environmental concerns of resource managers in the lower Mekong River basin. The issues identified, in priority order, were water quality, reduction in dry season flows, sedimentation, fisheries decline, wetland degradation, and flooding. An analysis of the avail...

ghourighol international wetland which is located at bostan-abad conuty in east azerbaijan province is known as one of the important tourism and promenade zone of iran due to its special natural gravities. therefore, studying tourism value of this place could express the importance of its protection, predicting needs, removing scarcities and the development of tourism. the aim of this research ...

Management of river salt loads in a complex and highly regulated river basin such as the San Joaquin River Basin of California presents significant challenges for current Information Technology. Computerbased numerical models are used as a means of simulating hydrologic processes and water quality within the basin and can be useful tools for organizing Basin data in a structured and readily acc...

1. Dispersal ability can influence the importance of dispersal relative to other processes organizing metacommunities, such as species sorting among habitats along environmental gradients. 2. We compare plants with different dispersal modes and habitat affinities, evaluating the roles of environmental and spatial controls on plant community composition in 128 wetlands within 10 km of old-growth...

wetlands in the lower reaches of songhua river (lrsr), northeast china, are rich in biodiversityand natural resources, which provide crucial staging and wintering habitats for various endangered species.however, in the past five decades, the size of this wetland area has decreased, and its quality has deteriorated because of increased natural and human activities. wetland restoration is critica...
