Conceptualizing Ecological Responses to Dam Removal: If You Remove It, What’s to Come?
One of the desired outcomes of dam decommissioning and removal is the recovery of aquatic and riparian ecosystems. To investigate this common objective, we synthesized information from empirical studies and ecological theory into conceptual models that depict key physical and biological links driving ecological responses to removing dams. We define models for three distinct spatial domains: upstream of the former reservoir, within the reservoir, and downstream of the removed dam. Emerging from these models are response trajectories that clarify potential pathways of ecological transitions in each domain. We illustrate that the responses are controlled by multiple causal pathways and feedback loops among physical and biological comp

Analysis about South Asian geopolitics tends to gravitate toward the often-competitive ties between China and
India. This tendency can be seen on many newsworthy issues, such as rival attempts to establish blue-water navies;
competitive efforts to shape how the region’s roads, bridges, and ports are funded and built; and the omnipresent
Pakistan issue. Such topics are undoubtedly important. But other practical, everyday policy concerns like water
sharing and usage often receive less attention, are combined with larger security or border concerns, or are dealt
with only when natural disasters occur. Yet water politics has far-reaching consequences for the prosperity and
security of China, India, and other neighboring countries alike. And while this transboundary issue is integral to

Achieving sustainable drainage
There has been much debate regarding the delivery of Sustainable Drainage Systems (SuDS)
through the planning system. Not only the extent to which SuDS are being included within
development proposals, but also the way in which they are then delivered: their integration within
a design; the quality and nature of the proposals; and whether they are used to deliver benefits
beyond the management of water quantity. In SuDS delivery, the first question to ask is: ‘is this
sustainable drainage, or just drainage?’

WATER STEWARDSHIP REVISITED Shifting the narrative from risk to value creation
With an alarming 81% decline in freshwater species abundance since 1970, millions of people at risk from water scarcity and pollution, and billions of dollars being lost by investors and companies from water risks, the need for action on water has never been greater. We are now collectively in a critical period in which the world needs companies, who both impact and are dependent upon freshwater, to step up and help solve the challenges facing both people and the planet through water stewardship. While the briefing is aimed primarily at companies who have already begun their water stewardship journey, companies new to the space, fellow NGOs, funders, public sector agencies and others may also find it useful.

Natural and managed watersheds show similar responses to recent climate change
Changes in climate are driving an intensification of the hydrologic cycle and leading to alterations of natural streamflow regimes. Human disturbances such as dams, land-cover change, and water diversions are thought to obscure climate signals in hydrologic systems. As a result, most studies of changing hydroclimatic conditions are limited to areas with natural streamflow. Here, we compare trends in observed streamflow from natural and human-modified watersheds in the United States and Canada for the 1981–2015 water years to evaluate whether comparable responses to climate change are present in both systems. We find that patterns and magnitudes of trends in median daily streamflow, daily streamflow variability, and daily extremes in human-modified watersheds are similar to those from nea

Manual técnico para una gestión óptima de la hidráulica en humedales restaurados para mejora del hábitat y de la calidad del agua
En la actualidad, la visión moderna de las zonas húmedas naturales que todavía permanecen en el planeta es totalmente diferente a la de hace unas decenas de años: se les reconoce unos valores ambientales que los convierten en ecosistemas de muy alto valor, ayudan a la protección de los recursos hídricos superficiales y subterráneos, mejoran la calidad de las aguas....

Climate change-induced increases in precipitation are reducing the potential for solar ultraviolet radiation to inactivate pathogens in surface waters
Climate change is accelerating the release of dissolved organic matter (DOM) to inland and coastal waters through increases in precipitation, thawing of permafrost, and changes in vegetation. Our modeling approach suggests that the selective absorption of ultraviolet radiation (UV) by DOM decreases the valuable ecosystem service wherein sunlight inactivates waterborne pathogens. Here we highlight the sensitivity of waterborne pathogens of humans and wildlife to solar UV, and use the DNA action spectrum to model how differences in water transparency and incident sunlight alter the ability of UV to inactivate waterborne pathogens. A case study demonstrates how heavy precipitation events can reduce the solar inactivation potential in Lake Michigan, which provides drinking water to over 10 mil

Zooplankton and Water Quality of the Ishim River in Northern Kazakhstan
The article presents data on a reconnaissance survey of the ecological condition in the middle reaches of the Ishim River in North Kazakhstan oblast. An assessment based on bioindication methods is given for the ecological condition of the river. The research presents data on the saprobity and quantitative indicators of zooplankton at different river stations. The presence of Ergasilus sieboldi Nordmann has been identified in the Sergeevskoe reservoir.
