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.

Ocean and coastal management regimes are increasingly subject to competing demands from stakeholders. Regulations must not only address fishing, recreation, and shipping, but also sand and gravel mining, gas pipelines, harbor/port development, offshore wind and tidal energy facilities, liquefied natural gas terminals, offshore aquaculture, and desalinization plants. The growing variety and intensity of ocean and coastal uses increases the call for a more holistic, comprehensive, and coordinated management approach that recognizes the often complex relationships between natural and human systems. For both economist and non-economist audiences, this book describes ways in which economic analysis can be an important tool to inform and improve ecosystem-based management (EBM). Topics include modeling economic impacts, benefit-cost analysis, spatial considerations in EBM, incentives and human behaviors, and accounting for uncertainty in policy analysis. Throughout the book the authors elucidate the different kinds of insights which can be gained from the use of different economic tools. In this rigorous and accessible work, the authors defy the conventional stereotype that economic perspectives necessarily favor the greatest commercial development. Instead, they demonstrate how comprehensive economic analyses consider the full range of potential services offered by marine and coastal ecosystems, including the conservation of biodiversity and creation of recreational opportunities.
