‘…and the evidence was irrefutable’: The politics of evidence in the World Commission on Dams

open access: yesGeographical Journal
Abstract Evidence‐based policy‐making increasingly shapes the practice of advisory bodies, including global environmental assessments (GEAs). Advocates point to the power of evidence (particularly, but not only scientific evidence) to improve policy‐making.

Silver Carp herding: A telemetry evaluation of efficacy and implications for design and application

open access: yesNorth American Journal of Fisheries Management, Volume 43, Issue 6, Page 1750-1764, December 2023., 2023
Abstract Objective The removal of invasive Silver Carp Hypophthalmichthys molitrix is a primary control action in North America. Strong avoidance responses to underwater sound and electricity have been shown to facilitate herding and mass removal of these fish.

Dam stories: Using narrative analysis to understand the debate over water security and the Waimea Community Dam

open access: yesNew Zealand Geographer, Volume 78, Issue 1, Page 51-62, April 2022., 2022
Abstract In this article we investigate why environmental debates swing in one direction or another by analysing the discursive construction of water security surrounding the Waimea Community Dam in Aotearoa New Zealand. Using narrative policy analysis based on interview and documentary data, we show how an initial dominant rural water security story ...

Individual energy dynamics reveal nonlinear interaction of stressors threatening migratory fish populations

open access: yesFunctional Ecology, Volume 35, Issue 3, Page 727-738, March 2021., 2021
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Migratory fish populations, like salmon, have dramatically declined for decades. Because of their extensive and energetically costly breeding migration, anadromous fish are sensitive to a variety of environmental stressors, in particular ...

Re‐operating dams for environmental flows: From recommendation to practice

open access: yesRiver Research and Applications, Volume 37, Issue 2, Page 176-186, February 2021., 2021
Abstract Dam construction and operation are known to alter the hydrology of rivers and degrade riverine ecosystems. In recent decades, the call to reverse these negative impacts by re‐operating dams has become stronger. Dams can support riverine ecosystems by releasing environmental flows (e‐flows).

Where walls of power meet the wall of money: Hydropower in the age of financialization

open access: yesSustainable Development, Volume 28, Issue 2, Page 405-412, March/April 2020., 2020
Abstract Their ability to absorb substantial capital makes hydropower dams attractive projects for the “wall of money.” Although global webs of dynamic financial flows enable megaspatial transformations with huge temporal impacts, their opacity and fragmentation obfuscate possibilities for democratic decision making and accountability.

Major dams and the challenge of achieving “No Net Loss” of biodiversity in the tropics

open access: yesSustainable Development, Volume 28, Issue 2, Page 435-443, March/April 2020., 2020
Abstract Dam construction is booming across tropical regions critical for global biodiversity and ecosystem service provision. The principle of “No Net Loss” (NNL)—under which biodiversity impacts of development projects are quantified and fully mitigated—is being increasingly applied to large infrastructure development worldwide, including dams.

The Integrated Hydropower Sustainability Assessment in Tajikistan: A Case Study of Rogun Hydropower Plant

open access: yesAdvances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
Tajikistan has formulated the strategy to rejuvenate the country through hydropower. The Rogun hydropower plant (HPP) is designed as the highest hydropower station, while its sustainability is also questioned due to a lack of comprehensive sustainability evaluation.

Sensitivity of Regulated Streamflow Regimes to Interannual Climate Variability

open access: yesEarth's Future, Volume 7, Issue 11, Page 1206-1219, November 2019., 2019
The simultaneous growth in climate‐driven alterations of the hydrologic cycle and global freshwater demand threatens the security of anthropogenic and ecologic uses of streamflows. However, the impact of damming on the response of river regimes to long‐term climate variability has not been fully disclosed yet.

A Multilayer Reservoir Thermal Stratification Module for Earth System Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 11, Issue 10, Page 3265-3283, October 2019., 2019
Abstract Thermal stratification in reservoirs is a critical process that regulates downstream riverine energy and biogeochemical cycling. Current stratification models either simplify vertical energy process, reservoir geometry or neglecting the effects of reservoir operation.
