- Despite recent advances, ecosystem service monitoring is limited by insufficient data, the complexity of social–ecological systems, and poor integration of information that tracks changes in ecosystems and economic activities. However, new information and communication technologies are revolutionizing the generation of, and access to, such data. Can researchers who are interested in ecological monitoring tap into these increased flows of information by “mining” the internet to detect “early-warning” signs that may signal abrupt ecological changes? Here, we explore the possibility of using web crawlers and internet-based information to complement conventional ecological monitoring, with a special emphasis on the prospects for avoiding “late warnings”, that is, when ecosystems have already shifted to less desirable states. Using examples from coral reef ecosystems, we explore the untapped potential, as well as the limitations, of relying on web-based information to monitor ecosystem services and forewarn us of negative ecological shifts.

Institutional and Political Leadership Dimensions of Cascading Ecological Crises

- While some of the future impacts of global environmental change such as some aspects of climate change can be projected and prepared for in advance, other effects are likely to surface as surprises - that is situations in which the behaviour in a system, or across systems, differs qualitatively from expectations. Here we analyse a set of institutional and political leadership challenges posed by 'cascading' ecological crises: abrupt ecological changes that propagate into societal crises that move through systems and spatial scales. We illustrate their underlying social and ecological drivers, and a range of institutional and political leadership challenges, which have been insufficiently elaborated by either crisis management researchers or institutional scholars. We conclude that even though these sorts of crises have parallels to other contingencies, there are a number of major differences resulting from the combination of a lack of early warnings, abrupt ecological change, and the mismatch between decision-making capabilities and the cross-scale dynamics of social-ecological change.
