Global Survey of Lake Restoration in Practice

Algal blooms are one of the most serious concerns for lakes worldwide

The Ecosystems Workstream of the World Water Quality Alliance invites lake restoration practitioners to complete a survey on the challenges they face, in order to identify the leading causes for failure/success of lake restoration and to draw recommendations for future initiatives.

The deadline for participation is 15 October 2021.

World Water Quality Alliance

The World Water Quality Alliance (WWQA) is an open community of practice that represents a voluntary and flexible global network of experts, practitioners and policymakers.

The WWQA advocates the central role of freshwater quality in achieving prosperity and sustainability.

It explores and communicates water quality risks in global, regional, national and local contexts and points towards solutions for maintaining and restoring ecosystem and human health and wellbeing.

It aims to serve countries throughout the lifetime of the 2030 Agenda for Sustainable Development and beyond.

WWQA Ecosystems Workstream

The WWQA Ecosystems Workstream was established in 2021 to support large-scale restoration initiatives that aim to prevent, halt and redress the destruction of freshwater ecosystems, focusing initially on water quality management in lakes and their catchment areas.

The WWQA Ecosystem Workstream is led by a core group of the UK Centre for Ecology & Hydrology (CEH), IHE-Delft, the World Bank Group, Wageningen University, UNEP, and the Joint Research Centre (JRC) of the European Commission.

It will work directly with lake restoration practitioners to support the development of novel restoration programmes focusing on delivering socio-economic and environmental gains, especially in developing economies.

Global Survey of Lake Restoration

The Global Survey of Lake Restoration in Practice is designed to collate experiences of lake restoration practitioners from around the world.

The data collected will be used to draft a White Paper on Lake Restoration (the names of the contributors will be included if they permit this) and inform future activities of World Water Quality Alliance Ecosystems Workstream.

All members of the global community of lake restoration practitioners are invited to fill in this survey (it will ask only 10-15 minutes of your time) and to share it with other interested practitioners.

Initial survey responses were already reviewed during two 'Investing for change through the World Water Quality Alliance' sessions at the SIWI World Water Week, which was held 23-27 August 2021.

The survey responses provided somewhat unexpected results, indicating climate change as the most important pressure affecting lake ecosystems, followed by hydrological modifications, nutrients from agriculture, and invasive species.

Poor understanding of pressures and their effects was marked as one of the most important reasons behind failures in lake restoration. New and multiple pressures may call for new approaches to lake restoration: both in setting restoration targets and devising restoration strategies,
