Degradation of freshwater ecosystems and the services they provide is a primary cause increasing water insecurity, raising need for integrated solutions to management. While methods characterizing multi-faceted challenges managing abound, tend emphasize either social or ecological dimensions fall short being truly integrative. This paper suggests that management sustainability systems needs consider linkages between human uses, governance. We present conceptualization resources as part an...
Managing transboundary river basins requires balancing tradeoffs of sustainable water use and coping with climate uncertainty. We demonstrate an integrated approach to exploring these issues through the lens a social-ecological system, combining remote in-situ earth observations, hydrologic models, social surveys. Specifically, we examine how change dam development could impact Se Kong, San Sre Pok rivers in Mekong region. find that will lead increased precipitation, necessitating shift...
Abstract Climate change will challenge managers to balance the freshwater needs of humans and wetlands. The Intergovernmental Panel on Change predicts that most regions world be exposed higher temperatures, 2 , more erratic precipitation, with some likely have alternating episodes intense flooding mega-drought. Coastal areas frequent saltwater inundation as sea levels rise. Local land desperately need intra-regional climate information for site-specific planning, management, restoration...
Natural ecosystems are fundamental to local water cycles and the ecosystem services that humans enjoy, such as provision, outdoor recreation, flood protection. However, integrating into resources management requires they be acknowledged, quantified, communicated decision-makers. We present an indicator framework incorporates supply of, demand for, services. This provides initial diagnostic for resource managers a mechanism evaluating tradeoffs through future scenarios. Building on risk...
Sustainable watershed management requires effective stakeholder engagement and knowledge co-production. Currently, most methods for co-production in the field are case-specific, applied an ad hoc manner, not tested across various spatial scales or water contexts. Moreover, these often evaluated, limiting our ability to learn from adapt them. We critically assess Freshwater Health Index (FHI), indicator-based platform co-production, which has been a variety of social-ecological systems. Using...
Sustainable water resource management is a wicked problem, fraught with uncertainties, an indeterminate scope, and divergent social values interests among stakeholders. To facilitate better of Southeast Asia’s transboundary Sesan, Sekong Srepok (3S) River basin, we used the Freshwater Health Index (FHI) to diagnose basin’s current likely future level freshwater health. We conditions for December 2016 as baseline, where Ecosystem Vitality Services scored 66 80, respectively, out possible 100,...
Summary For decades the floodplain forests of River Murray have endured effects prolonged water stress. This has resulted in significant crown dieback and loss condition. The Living (TLM) initiative aims to restore ecological health six Icon Sites along River. two eucalypts Red Gum ( Eucalyptus camaldulensis ) Black Box largiflorens that dominate at five are undergoing widespread decline. To enable effective management restoration these forests, we developed a standardised tree condition...
ABSTRACT River red gum ( Eucalyptus camaldulensis Denhn.) trees along the lower Murray, Australia, have suffered severe dieback as a result of river regulation and drought. As an environmental flow initiative, height Murray in South Australia was raised during period increased spring summer 2005–2006. This performed by increasing level rivers channel weirs. anabranch creeks on Chowilla floodplain through horizontal recharge freshened adjacent groundwater, providing water to riparian gums....
A new species of the genus Lycodon Fitzinger, 1826 is described from Cardamom Mountains southwest Cambodia. zoosvictoriae distinctly differs all other in Southeast Asia by a combination its morphometric characters and unique coloration. The has 17 dorsal scales at midbody; 2+2 temporals; 8 supralabials; 10 infralabials; loreal separated internasal orbit; 213 ventrals; 85 subcaudals; pale tan brown ground color; irregular dark blotches on anterior part, 31 transverse posterior part body 26...
Indicator systems can improve water governance by integrating and simplifying data on resources. However, to our knowledge, no indicator have been comprehensively assessed against the framework within which they operate. We assess policy relevance of Freshwater Health Index (FHI) frameworks Lao PDR, Cambodia, Viet Nam. These were chosen because FHI has applied transboundary Sesan, Srepok, Sekong (3S) river basin, traverses three nations. conduct an institutional analysis, assessing...
Abstract The Vulnerable fishing cat Prionailurus viverrinus faces a perilous future in South-east Asia. It was last sighted Cambodia 2003. We deployed 16 camera traps at four sites southern during January–May 2015 to determine if the still present country. Eight photograph/video captures of cats were recorded from mangroves Peam Krasop Wildlife Sanctuary and one Ream National Park, but there no records Botum Sakor Park or Prey Nup. A number other globally threatened species also photographed...

Indicators of hydrologic alteration and the range variability approach were used to assess effects river regulation on hydrology River Murray in South Australia. Two simulated data sets derived from Murray-Darling Basin Authority's MSM-Bigmod model compared for period 1895–2009. The first scenario assumed that levels extraction diversion as July 2009 (present) applicable entire period. second there no water extractions or regulatory structures system was natural. Whilst natural cycle a...
Abstract The delivery of environmental flows to riverine floodplains is often constrained by water scarcity and infrastructure. This means that areas floodplain are unable receive through mechanisms like dam release, weir pool surcharge artificial flooding low lying areas. study trials aquifer injection as a method providing stressed river red gum ( Eucalyptus camaldulensis ) on the lower River Murray. objective was inject fresh at top saline alluvial reduce root zone salinity improve...
Abstract Many of South Australia's remnant temperate native grasslands are degraded by introduced livestock grazing. As a conservation measure, grazing was excluded from three 50 × m exclosures in grazed grassland. After 4 years, removal had noticeable effect on the grassland structure, increasing basal vegetation cover. Grazing no significant either or exotic species richness, rather differences richness changed as result interannual differences, such amount rainfall that fell growing...
Abstract Saline irrigation drainage water along the semi‐arid lower River Murray is often disposed of into evaporation basins to prevent contamination downstream supplies. These are former ephemeral floodplain wetlands that have now become extremely ecologically degraded due high soil and salinity. An experimental flooding with freshwater was conducted at Loveday Disposal Basin in 2006 evaluate environmental benefits periodic freshwater. The salt balances permanent North South during...
ABSTRACT Lowland rivers impounded by weirs are often operated to provide stable water levels. In the lower River Murray, levels promote algal biofilms dominated stalked diatoms, filamentous green algae and Cyanobacteria. summer 2005–2006, Lock 5 weir pool was surcharged for environmental benefit. Algal grown on artificial substrates were compared following year when level remained stable. On both occasions, fixed at 300‐mm depth in river channel a connected wetland. During surcharge,...
