Book Description
The sustainable development of minerals, which are non-renewable resources, is a major challenge in today's world. In this regard the true definition of 'sustainability' is a debating point in itself: can such a concept exist with respect to non-renewable resources? Perhaps the ideal sustainability model is one that minimizes negative environmental impact and maximizes benefits to society, the economy and regional/national development. Developed and near-developed economies rely for commodity supplies on developing countries where major mining operations are often a mainstay of the domestic economy. Limited environmental regulation and low wages lead to charges of exploitation. Also, large numbers of people have no alternative to living by informal, often dangerous, 'artisanal' mining. This Special Publication gives examples from developing countries from all scales of mineral extraction. The volume reviews environmental, economic, health and social problems and highlights the need to solve these before sustainability can be achieved. The better solutions require mutual understanding, through full involvement of all stakeholders, education, training and investment so that small-scale and artisanal mines can grow into well-managed operations. At larger scales, most major international mining companies have now improved their practices and are monitoring their progress, although there is no room for complacency in this rapidly changing area.

Gravel Roads

Category : Gravel roads
Languages : en
Pages : 112
Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
