Available in PDF, EPUB and Kindle. Book excerpt: Sand and gravels are the unrecognised foundational material of our economies. They are mined the world over, with aggregates accounting for the largest volume of solid material extracted globally (Peduzzi, 2014; Beiser, 2018). At the same time, these materials cannot be produced from our terrestrial, riverine and marine environments in quantities needed to meet demand from a world of 10 billion people without effective policy, planning, regulation and management. Such actions remain largely unaddressed by decision makers in public or private sectors. It is time to challenge the paradigm of infinite sand resources through constructive dialogue and solution-finding. This report aims to be the starting point from which a productive global conversation on sand extraction can begin. This synthesis was produced following a United Nations Environment Programme expert roundtable event held on 11 October 2018 in Geneva, Switzerland. The discussions emphasised potential solutions for mitigating mineral sands and aggregates extraction impacts and generating adequate support for responsible consumption pathways. Expert views were collated and complemented with additional research and consultation to distil key messages on an agenda for tackling this issue in 2019 and beyond.

Book excerpt: The overuse of sand is 'one of the major sustainability challenges of the 21st-century.' - United Nations Environment Program, 2019 Sand is the hidden foundation of our society. In Sand Stories, Kiran Pereira maps out the big picture of why it is the most consumed commodity on the planet after water. The book also examines the impacts of our seemingly insatiable demand for sand on our global Sustainable Development Goals. The concern is that sand is a non-renewable resource and not every kind of sand is useful. While the number of sand's uses beyond glass and concrete is growing, its sources are not. The good news is that there are solutions to this alarming global problem including those that foster a circular economy. We now need the political will to enact them.

Book excerpt: 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. Among the different types of human interventions, mining of sand and gravel is the most disastrous one, as the activity threatens the very existence of river ecosystem. A better understanding of sand budget is necessary if the problems of river and coastal environments are to be solved.

Download or read book Sand Mining in African Coastal Regions written by Ibrahim Rotimi Aliu and published by Springer Nature. This book was released on 2022-10-31 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the drivers and impacts of sand mining in the coastal areas of Lagos Nigeria. Based on empirical evidence, sand mining activity is driven by a number of urbanization-related factors while sand mining impacts are underlined by a number of sustainability-related factors. Four urbanization components describe the drivers of sand mining and four sustainability components describe the impacts of sand mining in Lagos. This book concludes on the puzzling dilemma of sand mining that supports thriving urbanization but undermines environmental sustainability in Lagos. Of course, sand mining has strong implications for environmental sustainability in Lagos coastal areas. This book is of immense benefit to environmental planners, city administrators, students of environmental science and the general public who have regards for environmental management.
Download or read book River Sand Mining Modelling and Sustainable Practice written by Raj Kumar Bhattacharya and published by Springer Nature. This book was released on 2021-07-31 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide demand for sand and gravel is increasing daily, as the need for these materials continues to rise, for example in the construction sector, in land filling and for transportation sector based infrastructural projects. This results in over-extraction of sand from channel beds, and hampers the natural renewal of sediment, geological setup and morphological processes of the riverine system. In India, illegal sand mining (of alluvial channels) and gravel mining (of perennial channels) are two anthropogenic issues that negatively affect the sustainable drainage system. Along the Kangsabati River in India, the consequences of sand mining are very serious. The construction of Mukutmonipur Dam (1958) on the river causes huge sediment deposition along the middle and downstream areas, these same areas are also intensely mined for sand (instream and on the flood plain). Geospatial models are applied in order to better understand the state and the resilience of stream hydraulics, morphological and river ecosystem variables during pre-mining and post-mining stages, using micro-level datasets of the Kangsabati River. The book also includes practicable measures to minimize the environmental consequences of instream mining in respect to optimum sand mining. It discusses the threshold limits of each variable in stream hydraulics, morphological and river ecological regime, and also discusses the most affected variables. Consequently, all outputs will be very useful for students, researchers, academicians, decision makers and practitioners and will facilitate applying these techniques to create models for other river basins.

Book excerpt: The purpose of this paper is to examine sustainable construction practices with respect to the use of substitutes for sand in construction and the enforcement of the same through legislation. It is a well-known fact that the use of riverbed sand for construction purposes has gradually led to excessive sand mining. This has in turn affected the environment and further, the recent lack or high cost of availability of such sand has led to not only various malpractices, but also the need to find an eco-friendly cost effective substitute. Theoretical concerns: (1) the continuation of sand mining leads to the death of water bodies (2) the complete substitution of riverbed sand with manufactured sand would lead to excessive quarrying and thereby death of mountains (3) the malpractices that may be the outcome of both these activities. The complete substitution would lead to hazardous environmental impact. Thereby, there is a need to provide for a balance between the use of both these sand in construction. Such balance, be it through the additional use of other substitutes, can be achieved only through a legislative approach. Summary of the concern: This paper provides for an understanding of the necessity of sand mining, its process, and the impact of the same to the environment. The paper examines the effect of lack of availability of riverbed sand or rather, the high cost of availability of the same due to the ill-effects of excessive mining. It goes on to investigate the various cases in which such high cost of availability has resulted in malpractices in construction by various Developers, in particular, the instances of using filtered sand for construction which have resulted in structural deficiencies and in many cases collapse of the structure. In such cases, it is usually the public who is affected, be it as a victim of the collapse of the structure or as the investor in the project. This paper examines the various substitutes that may be used for sand, in particular, manufactured sand. It is also called crushed stone sand or artificial sand. The paper provides for a comprehensive understanding of the process manufacture of such sand, its properties, justifies its substitutability, and examines the pros and cons of the same. One of the problems that the paper focuses on is the aspect that manufactured sand may also have its own adverse effects on the environment, namely, increase in quarrying and the disappearance of mountains and hills in the process. Finally, this paper attempts to suggest the possible provisions of such legislation after the examination of various decisions of the Supreme Court, National Green Tribunal, and Committee Reports. Research methodology A doctrinal method of research purely based on various published articles in journals, newspapers, magazines, and books has been employed to achieve the purpose of this paper in accordance with the objectives of the Conference. Main arguments (1) There is an increasing need to substitute riverbed sand in order to protect water bodies and groundwater. This is evidenced by the various decisions of the Supreme Court and the National Green Tribunal to protect water bodies from the harmful effects of sand mining. Further, it is also evidenced by various articles in newspapers and magazines increasing the awareness about the problems and harms that can be attributed to sand mining. (2) The lack or high cost of availability of sand has led to malpractices such as the use of filtered sand evidenced by reported instances of structure collapse. (3) Manufactured sand, when used in the right proportion with riverbed sand or other substitutes helps achieve sustainable construction practice which has been evidenced by articles by various scholars.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers topics that addresses the global environmental issues, their challenges, and mitigation strategies for sustainable development. Some of the major challenges global environment is facing currently are global warming induced climate change because of which various extreme weather events such as flood, drought, cyclone, forest fires have increased. Industrialization with urbanization and human anthropogenic activities have caused detrimental effect on the environment resulting in environmental pollution (air and water pollution), deforestation, degradation of ecosystems, soil erosion, ground water depletion, drinking water scarcity, biodiversity loss, depletion of fossil fuels, etc. Therefore, it has become utmost necessary to switch to significant lifestyle stages along with conservation of natural resources for a sustainable environment. Sustainable environment may be defined as the practice of responsibly managing natural resources and protect overall ecosystem to support health and well-being of present and future generations. One of the major environment sustainability is the use of renewable sources of energy such as solar, wind, hydroelectric, and biomass which will reduce environmental pollution and also minimize resource misuse. At the same time, crop rotation, solid waste management, water treatment, wastewater treatment are some of the sustainable practices we must carry out for a sustainable environment. Hope, the content of the book gives an overview of recent developments, knowledge gaps related to new research areas related to environment and their future prospects.
Download or read book Vanishing Sands written by Orrin H. Pilkey and published by Duke University Press. This book was released on 2022-09-12 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a time of accelerating sea level rise and increasingly intensifying storms, the world’s sandy beaches and dunes have never been more crucial to protecting coastal environments. Yet, in order to meet the demands of large-scale construction projects, sand mining is stripping beaches and dunes, destroying environments, and exploiting labor in the process. The authors of Vanishing Sands track the devastating impact of legal and illegal sand mining over the past twenty years, ranging from Africa, Asia, and the Caribbean to South America and the eastern United States. They show how sand mining has reached crisis levels: beach, dune, and river ecosystems are in danger of being lost forever, while organized crime groups use deadly force to protect their illegal mining operations. Calling for immediate and widespread resistance to sand mining, the authors demonstrate that its cessation is paramount for saving not only beaches, dunes, and associated environments but also lives and tourism economies everywhere.
