Africa’s Lakes: Atlas of Our Changing Environment (UNEP, 2006)

Water is vital for our survival. Africa is the second largest and the second most populous continent after Asia. It is endowed with both natural and artificial lakes and is home to some of the largest lakes in the world. These lakes are used for fishing, recreation, transport, irrigation, power generation, disposal of waste and a variety of domestic purposes. Over the years, human factors combined with natural conditions of climate and geology have influenced their water quality and quantity to some extent. Negative impacts have resulted in environmental disruptions to some of the Lakes basins. This atlas vividly illustrates some of the changes people and nature have brought about on Africa's lakes -both good and bad- over the last decades and presents an overview analysis of Africa's lakes situation. Learn more.

Monitoring Water Quality of Inland Lakes using Remote Sensing, NASA - ARSET 

This advanced-level training will focus on using remote sensing observations from Landsat 8 and 9, Sentinel-2, and Sentinel-3 for assessing water quality parameters, including chlorophyll-a concentration, turbidity, and Total Suspended Solids (TSS) in inland lakes. This training will also highlight the importance of in situ measurements of these parameters, coincident with satellite observations, in developing methodologies for operational water quality monitoring. Learn more

Conventions

The Convention on the Protection and Use of Transboundary Watercourses and International Lakes 

The UNECE Water Convention is a unique legal and intergovernmental platform which promotes sustainable use of transboundary waters. Originally adopted as a regional treaty in 1992, it became a global instrument in 2016. Many countries outside the pan-European region are now in the process of accession to the Convention.

How Nature Can Help Address Water-related Challenges - Freshwater Ecosystems Technical Brief (UNEP-DHI)

This UNEP-DHI report highlights the potential of using freshwater ecosystems to implement nature-based solutions (NbS) to tackle the triple planetary crisis – climate change, nature and biodiversity loss, and pollution. Using lessons from Afghanistan, Albania, El Salvador, Haiti, Kenya, Morocco, and Tanzania, it showcases the potential for real livelihood and socioeconomic benefits that have been unlocked by implementing nature-based solutions through freshwater ecosystems. Learn more.

Towards a management strategy for microplastic pollution in the Laurentian Great Lakes – Ecological risk assessment and management (part 2) 

K.E. Hataley et al. Canadian Journal of Fisheries 7 Aquatic Sciences 80 (10), 1669-1678, 2023 - Over the past decade, plastic pollution has been documented throughout the Laurentian Great Lakes basin. Here, we demonstrate the application of a published ecological risk assessment and management framework for microplastics in aquatic environments by comparing proposed thresholds for risk to monitoring data from the Great Lakes region.

High Resolution Mapping of Nitrate Loads of a Reservoir Using an Uncrewed Surface Vehicle: Potential Opportunities and Challenges (AGU, 15 Nov 2023).

Abstract: Reliable nutrient load estimation of a reservoir is challenging due to inconsistent spatial extent and temporal frequency of water quality and quantity measurements. This study aims to collect consistent spatial extent and temporal frequency of water depths and nitrate concentrations of a reservoir in South Korea using uncrewed surface vehicle (USV). 

Global conservation priorities for wetlands and setting post-2025 targets (Nature, 2 Jan 2024).

Abstract: Wetland conservation is becoming increasingly important as wetland areas decline globally. However, no comprehensive global-scale mapping of wetland conservation priorities and targets has been published. This information is needed to extend the current protected area network and improve the conservation efficiency for wetlands. Here, we propose a cost-effective assessment model for wetland conservation by integrating wetland conservation value- and human impact-related indicators to identify global wetland conservation priorities. These priorities cover 28% of the potential global wetland distribution, and of that, only 44% is currently protected by existing protected areas. To protect more wetland conservation priorities, we propose three target-setting scenarios for protected area expansion that offer additional contributions of 9.40%, 42.40%, and 55.97%, respectively. These three global targets can be downscaled to the national level and used to update national wetland biodiversity conservation strategies and action plans under a harmonized legal and regulatory regime at different scales and jurisdictions.
