Water does not exist in isolation. It is an integral part of any ecosystem and as such, every major change to this ecosystem has hydrological impacts which then lead to sociological, economic and other environmental consequences. The world’s freshwater resources are under threat from a wide variety of factors. Many of them such as over-abstraction of water from rivers and aquifers, pollution from point and non-point sources, changing patterns of precipitation are popularly known, debated and discussed widely. However, there are other crucial factors with significant social, environmental and economic impacts that are less known. One such threat is an activity known as ‘sand mining’ also referred to as dredging or gravel mining.

… Contrary to literature that says sand mining is not as environmentally damaging as other kinds of mining, it may be even more so because of its insidious nature and the fact that its effects often take decades to surface.
—Kiran Pereira

Sand mining has several negative impacts.

It poses a threat to water security in several ways. Dredging results in lowering of the alluvial water table which, in turn, directly affects groundwater storage capacity (See Kondolf et al., 2001). Excessive dredging allows for saline intrusion into groundwater (Viswanathan, 2002). The lowered water table implies a rise in water costs, thus restricting access to only those who can afford it (Hoering, 2008). It results in habitat loss including destruction and fragmentation of fragile, endangered ecosystems and reduced species richness (See Myers, 1999, Global Witness, 2010).

Sand mining also causes increased shoreline erosion rates, especially when mined unscientifically (Byrnes et al., 2000) and decreases protection from sea water especially during ocean disasters (Myers, 1999). It also poses a threat to critical infrastructure such as bridges, roads, railway tracks (Kondolf et al., 2001). Sand mining has also been known to cause loss of livelihoods in several instances (See Hoering, 2008, Young and Griffith, 2009 and Viswanathan, 2002). Other macroeconomic impacts have also been observed such as changes in land use patterns (Myers 1999) and increased public health costs (Myers & Muhajir I997, Mensah, 1997).

The demand for sand is fuelled by numerous factors. It appears that sand has long been commoditized and is now entrenched in global trade. Table 1 below illustrates the high trade value of this commodity. Despite the high value of this trade, or perhaps because of it, the activity is surprisingly depoliticized except when there are public concerns in specific areas.

It is no surprise that sand is indispensable for many economic development activities such as road building and concrete production. It also has other familiar uses such as in glass-making for window panes, glassware, glazing for pottery, lenses, television tubes, mirrors, fibreglass reinforcement, lamps, stained glass art, lasers, insulators, telescopes, bottles and containers for alcohol, soft drinks, and food items like jams, pickles (USGS, 2011). However, it is also used in several concealed ways such as hydraulic fracturing applications (Scienceviews.com, 2003-2010), in the making of semi-conductors that are used in almost every electronic device today ranging from notebooks to mobile phones and even in cars. Sand is also a source for strategic minerals such as Silica, Garnets, Thorium and ores such as Titanium, Uranium, Zirconium, Ilmenite which are in turn used in applications too numerous to list here. Nonetheless, two examples can be given to illustrate the breadth of use:

a) Titanium is used in ‘Production of lightweight alloys, aircraft components (jet engines, aircraft frames), automotive components, joint replacement (hips ball and sockets), paints, watches, chemical processing equipment, marine equipment (rigging and other parts exposed to sea water), pulp and paper processing equipment, pipes and jewellery [sic]’ (IIED and WBCSD, 2002).

b) Heavy Minerals such as Rutile, Sillimanite and Monazite are also sourced from sand. They find use in in the paint industry, welding electrodes, ceramics, foundry and also various applications like plastics, sun screen, food colouring and biomedical applications (Corpwatch, 2007). The most astounding use in terms of volume however, is the creation of ‘new land’. For e.g. Around 500 million m3 of sand was reclaimed (from the ocean bed) for the Palm Island II (Jebel Ali) and Waterfront projects on the coast of Dubai. ‘This equates to a row of trucks encircling the Earth about 22 times’ (Jan De Nul Group, 2009).

Given this demand situation, let us explore the supply side of the equation which exhibits a great spatial and temporal mismatch.

Although sand is more than abundantly available in deserts, this sand is not popularly considered a ‘resource’ because the physical morphology of such sand is not considered suitable for construction and other industrial activities. For such uses, ‘good quality’ sand is sourced primarily from relatively limited sources. Marine and terrestrial deposits are the two main sources. Marine (offshore) and terrestrial deposits are the two main sources. Offshore dredging is far more expensive, requires specialized equipment and special environmental permits. Offshore dredging is far more expensive, requires specialized equipment and special environmental permits. It is consequently used mostly by developed economies such as the US and Europe. As for terrestrial sources, river channel deposits, residual soil deposits and floodplain alluvial deposits are the most usual ones (Gelabert, 1997 in Cambers, 1997). Although continuous excavation can deplete sources in decades, some sands are said to be laid down from around 115 million years ago (The Greensand Trust, 2010). With a rapidly urbanizing world, such a perpetual demand vis-à-vis a limited supply of an easily available resource such as sand creates a rather complex situation with many winners and losers. Problems associated with sand mining have been reported across many regions of the world (Young and Griffith, 2009).

Some examples include Australia (Ratcliffe, 1997; Stoltz, 2011), Cambodia (Global Witness, 2010), Ghana (Mensah, 1997), India (Hoering, 2008; Padmalal et al., 2008; Sekhar and Jayadev, 2003; Sreeba and Padmalal, 2011), Namibia (Hartman, 2010), Tanzania (Nyandwi, 2001), United States (Brynes et al., 2000; Brynes et al.,2004; Femmer,2002; Kondolf et al., 2001), Bolivia, Brazil, Paraguay, Argentina, and Uruguay (Halweil, 2000), Bosnia (Clancy, 2004). Island states in particular feel the acute tension between ‘development’ and the need to protect the coast. Numerous examples can be found in many of the Caribbean Islands such as Puerto Rico, Grenada, Tobago, Montesserat, British Virgin island and others (Cambers, 1997), Jamaica (Farrant et al., 2003), Sri Lanka (Gunaratne and Jayarooriya, n.d.), Indonesia (Kamis, 2011, The Jakarta Post, 2007) and Maldives (PTI, 2008, Jacob, 2010).

In terms of sheer volume, aggregates of construction minerals (such as sand and gravel) account for the largest material volumes mined in the world where the global production in 2000, was estimated to exceed 15 billion tonnes per year (IIED and WBCSD, 2002). The irony of this situation is that despite being extracted at such gargantuan rates, sand is classified as a ‘low value’ resource (Ibid) and also a ‘minor’ mineral resource even in legislation in many countries such as India (See MAC, 2007).

There is also literature that explicitly states that sand mining is not as environmentally destructive as other kinds of mining. For e.g. The United States Geological Survey (2011) states ‘Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.’ This paradigm is only a partial truth and needs to change because it robs science and politics of the incentive to explore alternatives.

The author researched this topic further through a case study based in India. Three villages Mahad, Toradi and Bankot were selected. These villages lie along the Western Ghats of India, a region that is one of the world’s ten ‘hottest biodiversity hotspots’, with at least 325 globally threatened species occurring there (Myers et al.,2000). The region is also a very important watershed region for India. Rampant sand mining, often illegal, with high degree of political involvement, has wreaked havoc in the area. In the current scheme of things, neither the environment nor the local people seem to have voice in the matter. Dredging in the area has been going on for the last 20 years and was initially welcomed because it brought a new form of employment. However, with mechanical dredging, several problems have surfaced over the last 10 years and locals have been demanding a stop to this activity. Locals and the NGO working with them have each used the Right to Information Act (RTI) to obtain reports of resolutions of various gram panchayats (local governments) that confirm this popular protest. Yet, sand mining continues unabated and most of the dredged sand is sent to Mumbai, the financial capital of India.

Several ill-effects were noted in the region and they far outweighed the positive impacts on the region. The negative impacts of sand mining in the region are given below:
As per law, no dredging was allowed during the night, but in reality it was said to continue non-stop over 24 hours, every day of the year. The constant noise of mechanised dredging all day and all night was a major inconvenience to the residents because it also hampered sleep and the functioning of primary and secondary schools in the area.
Several landslides with much casualty have been reported in the region and official reports attribute it to heavy rains. However, locals believe sand mining to be the root cause. As one person said, ‘It is like this, if you make a heap of grain and you will remove grains from the bottom, the grain at the top will naturally fall. The base of the mountain is in the river. When you remove sand from the river, what else will happen?’

Both Mahad and Toradi faced similar challenges in that they were located downstream from an industrial estate run by the Maharashtra Industrial Development Corporation (MIDC) which was said to discharge untreated and hazardous industrial effluents into the river, leading to massive fish kills. It also made the water unfit for agriculture.
The deep dredging had worsened the problem. Locals claimed that ancient wells had begun to run dry because of falling water tables. Removal of the sand had also removed the last barrier to the leaching chemicals dumped in the river (as mentioned above), thus allowing the chemicals to seep further inland making groundwater unfit for domestic consumption. A report on water quality by the government Primary Health Centre confirmed the worst suspicions of the locals with ‘4 hoi and 38 nahi’ (4 yes and 38 nos) on various parameters.

Fishing was also affected because it was seasonal and fishermen could not fish during monsoons. They did not have an alternate means of livelihood, especially during the off-season. Therefore, the rest of the 8 months of work completely determined their quality of life. One person said, ‘In the past, 5 people depended on one boat but today one boat can support only 1-2 people – can’t give wages. It is difficult to maintain families’. Another said, ‘No bank is willing to give us a loan. We need to educate our children but we can’t afford it.

Sand barges often damaged fishing nets and reduced their catch. There had also been occasions of collision with fishing boats but ‘no one was willing to register complaints.’ They spoke of barges shifting sand and clay which resulted not only in nets going under soil because of disturbance but also disturbed navigational channels which then hampered local fishing operations especially during low tide.

The constant noise and disturbance of breeding grounds was also changing the kind of fish that can survive in the river. Consequently, the high-value catch for the local fishermen has diminished. They also felt their life was ‘under pressure’ and they were constantly ‘afraid of being dashed by the barges’. Official statistics too confirm this trend of declining fish stocks, though they do not attribute it to sand mining. See Table 2 below.

Given the rapid rate of urbanization and the current rate of extraction of sand and the silent devastation left behind in its wake, the modern process of assigning value, economic or otherwise to resources seems sadly inchoate and needs to be re-evaluated. In matters of food, clothing and other activities, we are influenced in many ways by the physical setting in which we live – coastal, desert, mountainous or forest regions. But we are also proficient at changing the environment ‘with unprecedented speed and effect’ (National Academy of Sciences, 1969, p26).

… Despite the high value of this trade, or perhaps because of it, the activity is surprisingly depoliticized except when there are public concerns in specific areas.
—Kiran Pereira

With globalization, there is a tendency for infrastructure, especially urban ones to be similar across geographies (ibid). Roads, bridges, airport runways are soon becoming ubiquitous. Availability of sand or the lack thereof thus directly or indirectly affects all who partake in this cup of modernity. The immediate effects of the lack though are felt most by the local community. Contrary to literature that says sand mining is not as environmentally damaging as other kinds of mining, it may be even more so because of its insidious nature and the fact that its effects often take decades to surface. Mining for iron ore or bauxite may cause alteration of the landscape so violently that its ill-effects are impinged on the viewer’s consciousness instantly whereas the gradual transformation of sand into bridges, roads, houses, paints, glassware, and other things that are taken for granted in modern urban lives is almost imperceptible. To the non-local spectator, nothing seems to be lost in the process beyond the inconvenient depletion of sand and the creation of visible craters in some instances. Sand mining has an undeniable impact on water resources and the people dependent on them, especially when carried out in an unscientific manner.

The paradox of this ‘high volume – low value’ resource needs to be explored further, particularly by those in academia and policy circles.

Excerpts;

At the unearthly hour of 4am on Thursday, Krishna Nagar area near Jubilee Hills bustled with activity with a convoy of sand laden lorries parked on either side of the road and eager customers, comprising builders, masons, plot owners making a beeline negotiating the best deal for a full or half lorry of sand. The midnight-to-morning sand market (a routine feature every night) had customers jostling and haggling for the best deal, some even indulging in panic buying with traders hard selling that sand supply from neighbouring states would stop in a few days…

Traders at these sand markets admit that the ban has worked in their favour as they have more than doubled the price, making a better profit now.

“The cost of regular sand until recently was Rs 750 per ton but is now being sold for Rs 1,700 per ton. Fine sand that was sold for Rs 800 per ton is now going for as much as Rs 2,000 per ton…

… And sky is the limit for a ton of sand.”

Destroying Paradise To Make Concrete Blocks: Sand Mining In Sierra Leone

sierra-leone-sand-mining
Sierra Leone, beach sand mining. “Unlawful and unsustainable sand mining is destroying one of Sierra Leone’s prize assets: her beaches.” Captions and Photo source: Change.Org

Excerpts;

A new threat has emerged that risks destroying Sierra Leone’s eco-tourism untapped opportunities for sustainable development: Sand Mining.

“It began slowly on the beaches closer to Freetown, Hamilton and Lakka. Chinese and Senegalese companies in need of sand to make asphalt to build roads, or quarries mixing it with cement for concrete-block buildings surrounded by barbed wire, the new image of “success” and “development” in Freetown, very similar to a prison to the untrained eye.”

Then suddenly, around February of 2012, the free-sand-for-all bonanza exploded. Without permits, hundreds of trucks attacked the beaches on a daily basis, hiring local boys as daily laborers to destroy their own communities. Hamilton beach and Lakka beach quickly disappeared.

The landscape changed. The trees collapsed. The mangroves are gone; there is nothing to protect the coast now from rainstorms and flooding. And so the trucks, always more numerous in numbers, moved west, and quickly arrived to John Obey beach. Some communities were forward-thinking enough to turn down promises of quick riches and temporarily employment to their residents, others unfortunately less so.

Everyone gets a piece of the pie, the local community is bribed to allow their beaches to be ransacked, the district councilman in nearby Waterloo fill their pockets, and the authorities in Freetown turn a blind eye. ..” Filippo Bozotti / Tribewanted

Singapore, one of the world’s most prosperous and fastest growing economies, is being accused of expanding its coastline with illegally dredged sand from neighboring states.

Singapore accused of launching Sand Wars
The island city-state’s size has increased by over 20 per cent since the 1960s and demand for sand for lucrative land reclamation and development projects is higher than ever. However, recent bans on exporting sand introduced in Indonesia, Cambodia and Vietnam have cut off supplies and opened up a thriving smuggling trade. Thieves have begun making night-time raids on the picturesque sandy beaches of Indonesia and Malaysia, carving out millions of tons of coastline and leading to fears of an imminent environmental catastrophe on a swath of tropical islands.
