This book addresses most of the environmental impacts of sand mining from small rivers The problems and solutions addressed in this book are applicable to all rivers that drain through densely populated tropical coasts undergoing rapid economic growth. Many rivers in the world are drastically being altered to levels often beyond their natural resilience capability.
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
The earliest global traces of the impacts of mining on the environment, reconstructed from environmental archives, such as ice cores, peat bogs, lake and marine sediments, can be dated back to around 6500 BC. The first recorded global impact of mining was assigned to the Roman period due to Pbsmelting (Marx, Rashid, amp; Stromsoe, 2016).
Environmental Impact of mining, it has led to environmental degradation and problems for the people by the depletion of ground water levels in the villages situated on the river banks. Moreover, as these villages are situated in the border between Andhra Pradesh 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
Case studies of environmental impacts of sand mining and
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.

Excessive instream sand mining is a threat to Illambajar bridge and Nutanhut bridge. River embankments are also affected by river bed mining. Sand mining also affects the adjoining groundwater system. In Mongalkot and Ketugram Blocks (Burdwan), ground water level becomes lower than the past. Sand mining also generates extra vehicle traffic, which negatively impairs the environment and
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.
Urban growth is achieved 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 developing Central Business District, malls and private properties in city.

#0183;#32;Extensive sand mining in some rivers has lead to the collapse of river banks, destabilising structures such as bridges and causing influx of salt water. Landslides and coastal erosion are other factors that have had a negative impact on the environment in Sri Lanka.
The case is rather alarming in the small catchment rivers like those draining the southwestern coast of India due to limited sand resources in their alluvial reaches. Moreover, lack of adequate information on the environmental impact of river sand mining is a major lacuna challenging regulatory efforts in many developing countries. Therefore, a
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 remove the habitat from the mined zones. It leads to changes in its channel form, physical habitats and

Keywords: Assessment, Impacts, Gravel mining, Sand mining, Environment. 1. Introduction 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.
environment, where this practice of sand and soil mining is becoming an environmental issue as the demand for sand increases in industry and construction. Mining and its associated activities can be responsible for considerable environmental damage. In this article we are discussing about the direct and indirect impacts due to soil and sand
