Global Security and Resilience - Researcher Focus
As a society, we are fundamentally dependent on water for drinking, energy and food security. However, the declining quality and quantity of water has been highlighted by the World Economic Forum as the pre-eminent risk to society and the global economy. Ensuring access to clean and safe water for all is a real challenge and fundamental to alleviating poverty and developing more resilient, healthy and sustainable communities.

Global water monitoring
Experts hold very little data on the world’s 100 million lakes due to their geographical spread, coupled with the logistical and political difficulties of monitoring water. Therefore, protecting citizens from water scarcity, pollution and deleterious impacts, including harmful algal blooms, remains a serious challenge.
In a bid to tackle the issue, Andrew and his Stirling team lead the £2.9 million GloboLakes project, funded by the Natural Environment Research Council (NERC), which has established the world’s first satellite-based global lake surveillance system.
The innovative approach – involving a number of other UK universities, research institutes and overseas partners – uses earth observation technology to measure the absorption and reflection properties of light emanating from lakes, rivers and estuaries to reliably estimate the constituents within the water. This technique provides vital data on water quality, such as algal concentrations and harmful algal blooms, and mineral and organic matter.
While other scientists have developed satellite algorithms to monitor one or two lakes on a local scale, Professor Tyler’s team is the first to develop a capability to work across a range of optically complex waters globally. He added: “Our work is groundbreaking.”
