Abstract Water availability is a major factor constraining humanity's ability to meet the future food and energy needs of growing increasingly affluent human population. plays an important role in production energy, including renewable sources extraction unconventional fossil fuels that are expected become players security. The emergent competition for water between systems recognized concept “food‐energy‐water nexus.” nexus made even more complex by globalization agriculture rapid growth trade, which results massive virtual transfer among regions security some regions. This review explores multiple components food‐energy‐water highlights possible approaches could be used with limited resources planet. Despite clear tensions inherent meeting changing demand 21st century, linkages food, water, can offer opportunity synergistic strategies aimed at resilient security, such as circular economy.

Linkages between flow regime, biota, and ecosystem processes: Implications for river restoration

Science, Год журнала: 2019, Номер 365(6459)

Опубликована: Сен. 19, 2019

River ecosystems are highly biodiverse, influence global biogeochemical cycles, and provide valued services. However, humans increasingly degrading fluvial by altering their streamflows. Effective river restoration requires advancing our mechanistic understanding of how flow regimes affect biota ecosystem processes. Here, we review emerging advances in hydroecology relevant to this goal. Spatiotemporal variation exerts direct indirect control on the composition, structure, dynamics communities at local regional scales. Streamflows also processes, such as nutrient uptake transformation, organic matter processing, metabolism. We deepening biological not just static patterns, affected stream research nexus flow-biota-ecosystem processes is an early stage. illustrate frontier with evidence from altered regulated rivers urban streams. identify challenges that should be prioritized advance process-based restoration.

A decade ago, scientists and practitioners working in environmental water management crystallised the progress direction of flows science, practice policy The Brisbane Declaration Global Action Agenda (2007), during 10th International Riversymposium Environmental Flows Conference held Brisbane, Australia. 2007 highlights significance allocations for humans freshwater-dependent ecosystems, sets out a nine-point global action agenda. This was first consensus document that bought together diverse experiences across regions disciplines, significant setting common vision internationally. After uptake innovation flows, declaration agenda revisited at 20th Conference, Australia, 2017. objective to publicize achievements since update reflect collective progress, innovation, emerging challenges policy, science worldwide. paper on (2018) describes inclusive consultation processes guided review document. 2018 presents an urgent call protect restore aquatic ecosystems their biodiversity, intrinsic values ecosystem services, as central element integrated resources management, foundation achievement water-related Sustainable Development Goals. makes 35 actionable recommendations guide support implementation through legislation regulation, programs, research, linked by partnership arrangements involving stakeholders.

Abstract By presenting the most comprehensive GlObal geOreferenced Database of Dams to date containing more than 38,000 dams as well their associated catchments, we enable new and improved global analyses impact on society environment environmental change (for example land use climate change) catchments dams. This paper presents development database through systematic digitisation satellite imagery globally by a small team highlights various approaches bias estimation validation data. The following datasets are provided (a) raw digitised coordinates for location dam walls (that may be useful in machine learning identification from imagery), (b) vector file watershed each dam.

Beyond the natural flow regime? Broadening the hydro‐ecological foundation to meet environmental flows challenges in a non‐stationary world

Freshwater Biology, Год журнала: 2017, Номер 63(8), С. 1011 - 1021

Abstract The natural flow regime concept has contributed significantly to environmental flows (e‐flows) science and applications over the last 20 years. Natural regimes reflect long‐term, historical patterns of variability that have shaped riverine species’ adaptations continue shape community ecosystem structure function. This scientific perspective, however, carries with it important assumptions about climatic ecological stationarity in terms “reference” conditions provide a basis for comparing success or outcomes e‐flow interventions. Non‐stationarity climate other (temperature, sediment, nutrients) features (non‐native species spread) presents challenges science. Reliance on assumption restoration reference either hydrologic is no longer tenable, an expanded e‐flows foundation needed meet several facing future implementations. Currently recognised limitations contribute emergence research frontiers need further development. These are (1) shifting from static, regime‐based metrics dynamic, time‐varying characterisations; (2) expanding (and space–time scales) used primary reliance states include process (population) rates traits; (3) incorporating “non‐flow” (e.g. temperature, sediment) guide prioritisation likelihood success; (4) broadening incorporate more theory will predictive perspective managing remain understand response alterations inform management. However, under hydro‐climatic conditions, new imperative resilience emerging, is, identifying prescribing sustain robust, persistent socially valued characteristics flexible adaptive management framework.
