Abstract. Sand is a valuable resource for construction and other purposes, however sand mining often. result in serious environmental problems such as land degra dation, loss of agricultural lands...
Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses
Inland sand mining has an impact on biodiversity and habitat, deforestation of the land with the consequent elimination of the vegetation, pollution of the land, hydrology, air and even noise. Because of these impacts, local communities are the one that tend to bear the negative impacts of sand mining be it social, economic or environmental.
Sep 27, 2020#0183;#32;The environmental impact of this mining activity has become so serious that in 1997, the Cape Verdean government was forced to introduce legislation prohibiting sand
scribed sand mining as being damaging because it increases coastal erosion and brings in artificial structures that block the flow of sand in the seas Ghose, 1989;( Ashraf et al., 2010; Ashraf et al., 2011; Archive, 2012; Mills amp; Staats, 2016; Naples Daily News, 2017).
result in serious environmental problems such as land degradation, loss of agricultural lands and. biodiversity, as well increased poverty among people. This study assessed the environmental. impacts of inland sand mining in six selected local government areas of Ogun state, Nigeria.
Types of coastal sand mining in Morocco We observed several types of coastal sand mining south of Tangiers in Morocco in July, 2007. The following examples are listed in order of the degree of economic and environment al damage. The first approach, bluff top mining is the least damaging and
Sep 04, 2017#0183;#32;The worry is that sand sucked up and deposited back onto the sea floor could cause sediment plumes to disperse over a large area. This would reduce light, which could affect the growth and survival of animals and invertebrates in the area. Not only that, but the mining process could displace invertebrates that live in the sand and smother other life forms.
Sep 07, 2017#0183;#32;The article concludes by observing that there has been little indepth research into the environmental, social and political effects of sand mining, and calls for urgent action to rectify this.
Result of the field observations shows that destruction of landscape, reduction of farm and grazing land, collapsing river banks, deforestation and water pollution are the environmental effects that result due to sand and gravel mining in the area.
process of sand mining has accelerated coastal environmental degradation to an alarming rate. Biological Environment Sand mining is one of the main threats to the rich biodiversity alongside our perennial rivers and ephemeral water courses. It can destroy riverine vegetation, cause erosion, pollute water sources and
discriminate sand mining and severe environmental impacts such as habitat destruction, degradation of the aesthetic beauty of the surroundings, deforestation of floodplains, and modified stream structure and functionality (Hayer amp; Irwin 2008 and Kondolf 1997). There is paucity of information on the impact of sand mining in the Limpopo Province in
Rampant sand mining destroys environment and bio diversity, affects water security and causes land erosion. Developing countries like India, Cambodia and other Asian countries consider sand as a free and abundant natural resource which is practically inexhaustible.
Impacts of Sand Mining on Environment A Review
This, in turn, has had adverse effects on the natural path of groundwater flow in the area, resulting in a. decline in water levels13. Thus, the impact of sand mining in these three states has had a devastating impact on the ecological and riparian life.
What is the Impact of sand mining on inland biodiversity and rivers? The mining of aggregates in rivers can have an effect on pollution and change the level of water acidity (pH). Removing sediment from rivers causes the river to cut its channel through the bed of the valley floor (or channel incision) both upstream and downstream of the extraction site.
more than 50 mining sites to document the impact of large scale surface mining on agricultural and forest land. Water is most important element in processing and refining silica sand and, therefore, to study the nature and amount of water use/reuse, and volume of vehicular movement
Mar 09, 2017#0183;#32;Effects of Mining on the Environment and Wildlife. March 9, 2017 /. in News / by access Mining is an inherently destructive industry, and the mining effects of even a single operation can have a severe impact on the environment and the wildlife that lives nearby. Although there are some regulations in place that are intended to minimize the damage, they are not enough to
Other environmental impacts of sand mining that were identi ed in the study area include landform instability which is due to the removal of riparian vegetation.
Dec 10, 2019#0183;#32;Abstract. Sand mining is a human activity that is increasing in inland waters and has profound effects on entire aquatic ecosystems. However, current knowledge of the effects of sand mining on freshwater lake ecosystems remains limited, especially for biotic communities. Here, we investigated the responses of macroinvertebrates to indiscriminate sand mining in a large shallow
Instream sand mining activities will have an impact upon the river''s water quality. Impacts include increased shortterm 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 transportation vehicles.

When sand is taken out of the water it increases the risk of landslides, which can lead to loss of agricultural land and/or damage to dwellings. Sand''s many uses require a significant dredging industry, raising environmental concerns over fish depletion, landslides, and flooding.
To identify the various sand mining/excavation sites along River Ethiope in Abraka and Eku. To investigate the effects of sand excavation on coastal areas where excavation is done in AbrakaEku region along the River Ethiope. To proffer solutions to the sustainability of the environment where sand excavation is going on in the area studied.
