Water resilience for human prosperity
New book introduces new framework for water governance and management
Water is the bloodstream of nature and wise stewardship of freshwater, from the very local to the regional, is central to human development and prosperity. But over-use and mismanagement of freshwater resources now threatens the functioning of ecosystems that are crucial to human activities.
The new book Water Resilience for Human Prosperity, analyses the problems and provides examples of successful water resource management with main focus on freshwater use for current and future food production. The key message of the book that by identifying and understanding the available water resources for humans and nature, we can find solutions that provide prosperity for more people and for a longer time.
The two major forces impacting the water cycle are human-induced: land-use change and consumption for agriculture, households and industries. Understanding the feedbacks in social-ecological systems can help in building water resilience, argue the authors.
"Water is key for maintaining and enhancing the resilience of social-ecological systems that we depend on," says Johan Rockström, director of Stockholm Resilience Centre (SRC) who is lead author of the book written together with Beijer Institute director Carl Folke and other colleagues at SRC, Stockholm Environment Institute and Potsdam Institute for Climate Impact Research.

How a gentle nudge can change our behaviour
No registration is needed
Short course: Applied Methods Related to Regime Shifts in Social-Ecological Systems
The course is arranged by the Beijer Institute in conjunction with the World Conference of Environmental and Resource Economists, WCERE 2014 June 27-28, 2014 in Istanbul, Turkey. Its target audience is researchers from developing and transition countries, especially encouraging applicants from the regional environmental economics networks CEEPA, EEPSEA, LACEEP, and SANDEE.

Nine conditions for a more all-purpose kind of resilience
Through history unprecedented and unexpected catastrophes have occurred, such as the Krakatao eruption 1883, killing 36 000 and lowering the Earth’s temperature the following years, through the ash particles released. Examples from recent years could be the Japan earthquake and tsunami of 2011 or the mad cow disease outbreak.
To better cope with such events requires general resilience, and economists and ecologists on the Beijer Institute’s annual Askö meeting 2010, in a recently published paper in the journal Sustainability point to the increasing need for a "general resilience" and they suggest nine important conditions to achieve it.
"General resilience is the capacity of social-ecological systems to adapt or transform in response to unfamiliar, unexpected and extreme shocks. Processes for building general resilience are an emerging and crucially important area of research," write the team of scientists, including Beijer Institute researchers Anne-Sophie Crepin, Gustav Engström, Carl Folke and Karl-Göran Mäler together with Economics Laureate Kenneth Arrow and others .
Absorb shocks of all kind
Hence, general resilience is about strengthening the capacity to absorb shocks like storms and floods, even financial meltdowns. Building such broad resilience to unknown disturbances is far more difficult than planning for specific resilience to known types of disturbances. In fact, large-scale disturbances like the mad cow disease and the huge Japan earthquake and tsunami, are outside the scope of experience. The latter example was an earthquake which was extraordinarily powerful and triggered a tsunami with a 14 meter wave that breached the seawalls designed for the expected maximum wave height of 5.7 meter. In addition, the tsunami damaged nuclear power stations by shutting down back up diesel generators which were located in “safe" places on the assumption that the sea walls would hold.
"Such events are unusually so intense or extensive that they require another type of resilience building," argue the authors.
"We should build more 'all-purpose kind' of resilience, although building such resilience is far more difficult and costly than planning for known types of disturbance."
Among the conditions that enable general resilience, the authors of the new paper include nine important aspects: (1) diversity, (2) modularity, (3) openness, (4) reserves, (5) feedbacks, (6) nestedness, (7) monitoring, (8) leadership, and (9) trust.
Diversity, openness and trust
Diversity, for example, entails species that have similar functions but different responses to disturbance (response diversity), so the function is maintained even if one component of an ecosystem is damaged. Diversity of perspectives and experience also matters as much as individual ability, when teams of people are solving complex problems.
Modularity is important because it helps to contain disturbances by separating social-ecological systems from each other, e.g. land management with prescribed fire that uses firebreaks to limit the spread of the fire. Similarly, quarantine mechanisms may restrict the spread of epidemics or invasive species.
In other cases, openness of a social-ecological system might be the key to general resilience, e.g. seed dispersal as a key to recovery from large infrequent forest fires. Hence, there are a number of trade-offs between modularity and openness that is well understood for some social-ecological systems, but not for others.
"Development of trust is another important aspect when building general resilience, determining whether people will be able to collaborate effectively in relation to unfamiliar, unexpected and extreme shocks," the authors conclude.
