Prof. Angela Arthington - Progress with environmental flows to maintain healthy rivers and healthy societies

The science and practical applications of environmental flows (e-flows) have advanced rapidly since the early 1980s. E-flows serve as a means to protect the flow regimes and ecosystems of undeveloped rivers, and conversely, as a means to restore the flow regimes and ecological health of regulated rivers. From simple beginnings in the form of ‘minimum flows’ to ensure adequate aquatic habitat for fish, the e-flows concept has expanded to embrace the water requirements of rivers and other aquatic habitats as ecosystems. “Holistic” ecosystem methods aim to devise a flow regime that will ...

Prof. Karl Wantzen - Development(s) of the River Culture Concept

Rivers give rhythm to all life in their catchments. Floods and droughts trigger both, etho-physiological adaptations by biota, resulting in biodiversity, and one species, H. sapiens, resulting in cultural diversity. The River Culture Concept (2016) takes an attempt to re-establish harmony between humans and rivers. The five tenets of the concept include, (i)  reconsidering priorities on the use of riverine assets, (ii) integrating the natural flow regime into river management, (iii) rediscovering traditional ecological knowledge (and by no means all ancient use forms), (iv) copying natural adaptive strategies (“ecosystem bionics”), and ...

Dr Simone Langhans - Weaving together plural values in freshwater management: a case study of the Upper Clutha catchment in Aotearoa New Zealand

Public participation is an effective way to resolve the tensions between contested objectives, while maintaining ecological integrity. New Zealand is one of the few countries that takes a collaborative approach to environmental management, mandating that management plans for catchments are co-created with local communities based on the concept te Mana o te Wai. The National Policy Statement for Freshwater Management (NPS-FM) gives guidelines on objectives and attributes that must be considered to safeguard freshwater values. They also specify minimum quality standards, but allow communities to set higher standards and to add more ...

Dr Fengzhi He & Dr Rebecca Tharme - Freshwater megafauna: diversity, status, and cultural importance

Megafauna species play important ecological roles. Owing to their intrinsic characteristics such as large habitat requirements, long lifespan, and late maturity they are particularly susceptible to extinction. Freshwater megafauna species, i.e. freshwater animals that can reach a body mass of 30 kg or more, are also vulnerable to anthropogenic impacts. There are intense and growing threats such as overexploitation, dam construction, habitat degradation, pollution, and biological invasions in diversity hotspots of freshwater megafauna including the Amazon, Congo, Mekong, and Ganges-Brahmaputra river basins. Consequently, half of all assessed species are considered as ...
