Global Sand Observatory Initiative
The Global Sand Observatory is a new concept proposal which follows consultations with countries aiming for the future creation of a knowledge hub on sand for supporting decision making on the sustainability issue of sand extraction and use.
Sand resource governance is one of the greatest sustainability challenges of the 21st century.
Sand, gravels and aggregates are the second most-exploited natural resources in the world after water. The use of these materials has tripled over the last two decades reaching between 40-50 billion metric tons/year. This trend is expected to continue as demand is still growing due to urbanisation, population growth and infrastructure development trends. It is increasingly difficult to source sand and gravel close to urban and industrial centres because of access issues, social acceptance and other factors. As a result, extraction locations are shifting to more fragile environments such as rivers, coastlines, and oceans - which coupled with the increased demand - is severely impacting these ecosystems. Practices like these are happening all over the world causing environmental and social sustainability problems on both a local and global scale.
A number of international organisations, governments, journalists, civil society groups, research centres and companies around the world have been placing this previously unaddressed topic on the environmental political agenda in recent years. As a result, there is a growing call for improved sustainability practices in sand extraction within major use sectors, such as cement production, construction and land reclamation.
Progress on this agenda cannot be secured without some basic reliable data and statistics on where, how and for what purpose sand and gravel is being extracted. Advancing this fundamental knowledge is our main focus in the first phase of the Global Sand Observatory initiative.
We are currently exploring partnership possibilities for future collaborations, should the mandate be accepted. Please find below publications which were produced or collected following the mandate provided by UNEA5 resolution 12, which requested GRID-Geneva to further strengthen scientific, technical and policy knowledge with regard to sand extraction and use.

Title: the Global Marine Sand Watch
Abstract:UNEP/GRID-Geneva is leading the Global Marine Sand Watch, a platform to help countries and stakeholders monitor dredging activities in near real-time towards the goal of capacity building, development of guidelines and best practices for sand extraction. Built in collaboration with the Global Fishing Watch, the University of California Santa Barbara and Google, the platform will enable nation states and stakeholders to address the unprecedented and quickly increasing socio-economic demands for marine sand resources using near-real time data and information. |

Title: Ocean Sand: Risks & Opportunities for Sustainability & Equity
Place: online
Abstract: This was a side event held at the 2022 UN Ocean Conference to put sand on the ocean sustainability agenda and identify promising scientific, technical and policy opportunities for sand stewardship. Panelists will discuss the importance of sand in the ocean economy, the impacts of its extraction on ecosystems and coastal communities, the role of financial institutions in incentivising better practices, as well as promising breakthroughs in monitoring and impact assessments. Particular attention will be paid to the equity dimension of ocean sand and need for international partnerships for better sand resource governance. The event is organised by UNEP-GRID/Geneva and the Stockholm Resilience Centre (Stockholm University). It is co-hosted with the Stockholm Resilience Centre, UNEP’s Finance Initiative and the UN Global Compact. |
