Paying to restore urban streams

March 25, 2018

Rivers and streams provide many ecosystem services, including the supply and purification of water, climate regulation, flood protection, fisheries, aesthetic values and recreation.  In urban settings, the loss of stream ecosystem services as a result of pollution, erosion and habitat degradation has prompted widespread attempts at environmental repair. However, although levels of investment in urban […]

Environmentalism with attitude: the importance of psychology

Comments Off on Environmentalism with attitude: the importance of psychology

Although public support can be crucial in achieving aquatic management goals, management approaches often receive little input from disciplines that focus on the relationship between humans and the environment.  A recently-published paper used case studies, some specifically relating to freshwater issues, to show how environmental psychology and natural sciences can work together to successfully tackle […]

Comments Off on Volunteers collect high quality data

Volunteer community groups are increasingly active in environmental monitoring, and often have the capacity to collect large amounts of data that can potentially complement or replace information gathered by management agencies. However, in some instances, scientists have expressed reservations about the reliability of community-generated data. New Zealand researchers compared the level of agreement between stream […]

Lake Urmia, in western Iran, is a Ramsar-listed Biosphere Reserve and one of the world’s most significant salt lakes. Until recent times it had a length of 140 km. However, its size has been reduced by 90% as a result of forest destruction and short-sighted water policies. A recently-published case study of Lake Urmia offers […]

River restoration: does better monitoring mean fuzzier conclusions?

Comments Off on River restoration: does better monitoring mean fuzzier conclusions?

Although stream restoration activities are commonplace, the assessment of project success has been patchy, and in many cases little or no time has been allowed for the comparison of sites before and after restoration. In a study of restoration evaluation, French researchers collected data on 44 stream restoration projects, each from a different river, by […]

What prompts group action to protect the environment?

Comments Off on What prompts group action to protect the environment?

There are plenty of studies that describe how group action can improve the environmental quality of local streams, but relatively few have examined how collaboration is prompted in the first place. It seems that shifts in environmental policy require some sort of catalyst (trigger event) as well as a particular set of background conditions. An […]

Ecosystem services: the best hope for aquatic conservation?

Comments Off on Ecosystem services: the best hope for aquatic conservation?

In an editorial in the journal Aquatic Conservation, S.J. Ormerod offers a perspective on key themes, challenges and new opportunities for river conservation. In recent years a range of policy and legal instruments have been introduced to protect river ecosystems. While these changes are delivering real benefits, they also have weaknesses. For example, although the […]
