In this study, the effects of sand mining activities on the soil organic carbon (SOC) storage, different N-removal processes (Feammox, anammox, and denitrification), and composition of the relative bacterial community at a depth of 0-40 cm were determined based on investigations in riparian sand mining areas and adjacent forestlands.
Instream sand mining activities will have an impact upon the rivers water quality. Impacts include increased short-term turbidity at the mining site due to resuspension of sediment, sedimentation due to stockpiling and dumping of excess mining materials and organic particulate matter, and oil spills or leakage from excavation machinery and ...
Apr 03, 2014 The turbidity profiles were collected in September 2012 (Fig. 5a) at three points before mining location, immediately at the sand mining extraction site and near the river mouth, located about 350 m away from the mining location, and showed a strong influence of mining activities on transparency. The Secchi depth immediately dropped below 0.1 ...
The aim of the study was to assess the consequences of sand mining activities on soil erosion, vegetation clearance and landslide levels in the O.R. Tambo district.

Sand mining on the ridge is carried out using simple hand tools like shovels and diggers. Every five days, 801 tippers of sand are removed from the ridge to Maiduguri and environs. Sand mining has seriously affected agricultural activities around the ridge.
and effects of illegal mining (galamsey). The main impacts identified are on economic activities, health, social life and employment while the effects include those on economic activities, health, social life, environment, agriculture and education. It was then
Apr 04, 2015 Moreover, in 2012 the ministry issued a statement stopping all beaches sand mining activities throughout Liberia. Under the statement, the Ministry of Lands Mines and Energy also considered all beach sand mining after 2012 as illegal activities. Despite these steps made by the Ministry, there are still problems in the sectors.
the site. Sand mining various environments is presented below. River Environment Impact of Sand mining Sand is vital for sustenance of rivers. The sand mining has several impacts on the river environment. Sand mining disturbs and completely

pollution potential due to mining activities (Ashraf et al., 2010). The mining of sand resources from rivers and ex-mining areas is a common practice and may lead to destruction of public assets as well as impacts or increase stress on commercial and non commercial living resources that utilize these areas (Ashraf et al., 2011). Tree
Unfortunately, the extensive use of sand and the increase in mining activities have neg- ative environmental impacts on both the local and global levels 10, and urgent measures are needed to limit these effects.
This study investigates the impact of sand dredging activities on coastal ecosystem and community survival around Ibeshe area of the Lagos Lagoon, Nigeria. Surface water and bottom sediment samples were collected from locations partitioned into Dredged Area (DA) and Undredged Area (UA) in the lagoon for laboratory analyses. Questionnaires were administered
Mining and Quarrying ImpactsIntroductionMining and quarrying extract a wide range of useful materials from the ground such as coal, metals, and stone. These substances are used widely in building and manufacturing industry, while precious stones have long been used for adornment and decoration. Mining and quarrying involve investigating potential sites of extraction, then
e) Effects on hydrological cycle, rainfall and climate. Lowering of water table In the process of mining, when digging is undertaken, and when such activity extends below the water table, the working areas experience an inflow of water so much so that in some cases inundation takes place extending the danger of loss of life and property. Thus
environs of the sand and gravel mining activities along the valley (Figure 1). The mining activities are , however, not evenly distribited along the valley and among the villages. To the west and south-west gravel mining dominates. The mining affects five villages which are located between the mining sites and the river.
Feb 05, 2020 Here, we use sand mining as a generic term to embrace extraction of riverine aggregates regardless of particle size. Sand mining activities are one of many recognized pressures affecting riverine ecosystems, where biodiversity is already in rapid decline (World Wildlife Fund, 2018).
Feb 05, 2019 The Hidden Environmental Toll of Mining the Worlds Sand. By far the largest mining endeavor globally is digging up sand, mainly for the concrete that goes into buildings. But this little-noticed and largely unregulated activity has serious costs damaging rivers, wreaking havoc on coastal ecosystems, and even wiping away entire islands.

Dec 19, 2002 However, the process of sand mining has accelerated coastal environmental degradation to an alarming rate in many areas. As a result the government has been compelled to spend millions of dollars to combat sea erosion. This paper examines the causes and effects of coastal sand mining in three communities in the Ahanta West District of Ghana.
The paper discusses the imperatives of sand mining and the environmental. impacts using selected case histories in the Niger Delta and elsewhere. The. continuation of sand mining in spite of the associated adverse environmental. effects, have been linked to the creation of new usable land from marginal.

The present study seek to investigate the impacts of sand dredging on the ecology of Lagos lagoon in Ibeshe coastal community area, viz-a-viz its influence on water composition, fish and fisheries distribution as well as the perception of coastal community dwellers to environmental effects of sand dredging are discussed. 2.
and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material. On the other hand, the number of studies focused on the impacts of mining and mineral processing
Nov 11, 2017 Sand is a mineral as defined under Section 3 (e) of Mines and Minerals Development and Regulation Act, 1957 (MMDR Act). This act empowers government and state to make any laws to prevent illegal mining. Sand mining is a practice that is used to extract sand, mainly through open pit. This demand is exalting at alarming rates a result of ever ...
Ashraf et al. (2011) reported that In-stream sand mining activities causes water to be turbid, thereby interfering with the penetration of sunlight for benthic organisms. Oil spills or leakage from mining machinery into water hamper free circulation
Often the conditions imposed on the approval for sand mining activities are expressed in administrative terms, without technical consideration of their potential impact on the ecosystem. Physical impacts of sand mining include reduction of water quality and destabilization of the stream bed and banks.
Although sand mining contributes to the construction of buildings and development, its negative effects include the permanent loss of sand in areas, as well as major habitat destruction. Sand mining is regulated by law in many places, but is still often done illegally.
Apr 03, 2014 High water level and strong solar radiation increased temperature stratification. River discharges during the wet season, and unsustainable sand mining activities led to an increased turbidity exceeding 100 NTU, and reduced transparency, which changed the temperature variation and subsequently altered the water quality pattern.
Sand mining and its associated activities serves as a source of livelihoods for entire communities whilst on the other hand it can trigger conflicts a nd violation of human rights. This study is...
