roads and other structures. This paper reviewed the sand mining impacts on river, dune, marine, hydrological, biological and sociological environments with some worldwide case studies. Keywords: Sand mining, river, dune, beach, hydrological, biological, sociological I INTRODUCTION Sand mining is a practice that is used to
sand andis purposely saved stacked aside in heaps. During sand extraction, topsoil layer is peeled and stacked aside and exposed sand is excavated to a depth of 1012 m. Afterwards, stacked topsoil is spread and mixed with sand bed. As mining proceeds further, the mined fields are handed over to the owner for cultivation.
Sand mining is the removal of sand from their natural configuration. Sand is used for all kinds of projects like land reclamations, the construction of artificial islands and coastline stabilization. These projects have economical and social benefits, but sand mining can also
The global demand for plain old sand is so high that illegal mines are everywhere, and mafias around the world are killing for the stuff.
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 lands of the region and sustained supply of aggregates for expansion of civil infrastructure.
The paper examined sand and gravel mining activities both on land and the rivers as a business venture in Minna emirate council of Niger state, Nigeria.

Sand mining is the process of removal of sand and gravel where this practice is becoming an environmental issue as the demand for sand increases in industry and construction. In almost every mineral bearing region, soil mining and land degradation have been inseparably connected.

This paper summarizes the results of a literature review into the impacts of riverine sand mining on freshwater ecosystems. The aim of the review was to provide an understanding of the range of observed impacts related to sand mining activities and to guide future research directions.
through sand and gravel mining for construction of modern, attractive and durable structures. The study examined positive and negative environmental impacts of the continuous removal of river sand, pit sand and gravel from sampled rivers and open areas surrounding Gaborone
Sand and gravel mining refers to the actual process of removal of sand or gravel from a place of their occurrence (Langer, 2003). The places of sand and gravel occurrence are oceans, rivers, streams, flood plains or hills and mountains. The increase in demand for sand and gravel for construction purposes has placed immense pressure on sand and
sand. Environmentally, mining along riverbanks and coastlines has had irrevocable effects, though it has had many social impacts as well. Illegal sand mining in the mainland, as well as in Zanzibar, can often create bad relationships between miners and property owners or communities.

#0183;#32;Sand is not only a precious mineral but also protecting the environment, buffer against strong tidal waves and storm, habitat for crustacean species and marine organisms, used for making concrete, filling roads, building sites, brickmaking, making glass, sandpapers, reclamations, and in our tourism industry in beach attractions. Sand mining is the process of removal of sand and gravel
#0183;#32;Otamiri River is of great importance to the socioeconomic wellbeing of Owerri Community. The banks help to protect and sustain the stability of the adjacent terrestrial ecosystem. Continued sand mining activities in the river is of serious concern to the inhabitants of the area. This study therefore investigated the impact of sand mining on the river water quality and the banks morphology.
