Sustainability: global vs local level

The following drawing shows the idea of global sustainability. Where human systems grow within the boundaries of Earth’s natural systems. In this case, a global degradation process of nature endanger human survival. This second drawing shows the idea of sustainability at local level and for a particular ecological unit: intertidal seagrass meadows. Local people interact and benefit…

Resilience and policy

A lot of work on resilience has focused on the capacity to absorb shocks and still maintain function. But, there is also another aspect of resilience that concerns the capacity for renewal, re-organization and development, which has been less in focus but is essential for the sustainability discourse. In a resilient social-ecological system, disturbance has…

Eli the eel: A mysterious migration

They’re slippery. They’re slithery. And while they totally look like underwater snakes, eels are, in fact, unique fish that can breathe  through their skin and even survive out of water. James Prosek tracks the life journey of Eli the Anguilla eel as she (yes, she) travels her mysterious “backward” migration from the sea to fresh…

Detecting seagrass spatial features using Remote sensing

Remotely sensed data and imagery have been widely applied over the years to coastal environments with varying degrees of success, largely dependent upon the application. Aerial photography, in particular, emerges as a major source of information that has considerable appeal for many coastal applications, primarily because of a user-requirement and desire for “high” spatial detail…

Rationale for including social considerations in conservation planning

From the perspective of planners – is that the actions that emerge are more likely to achieve their goals and to be more sustainable. Explicitly including social considerations also creates the opportunity for planning processes to become more realistic and inclusive, clarifying the hard choices and complex trade-offs between and within conservation and other objectives.…
