A visually apparent but scientifically untested outcome of land-use change is homogenization across urban areas, where neighborhoods in different parts of the country have similar patterns of roads, residential lots, commercial areas, and aquatic features. We hypothesize that this homogenization extends to ecological structure and also to ecosystem functions such as carbon dynamics and microclimate, with continental-scale implications. Further, we suggest that understanding urban homogenization will provide the basis for understanding the impacts of urban land-use change from local to continental scales. Here, we show how multi-scale, multi-disciplinary datasets from six metropolitan areas that cover the major climatic regions of …


How Defining Planetary Boundaries Can Transform Our Approach To Growth, W. L. Steffen, Johan Rockström, Robert Costanza May 2011

How Defining Planetary Boundaries Can Transform Our Approach To Growth, W. L. Steffen, Johan Rockström, Robert Costanza

Institute for Sustainable Solutions Publications and Presentations

The article focuses on the importance to identify safe boundaries based on the fundamental characteristics of our planet to address the growing threats of climate change. It highlights the rapid transition of the planet from the stable Holocene state to an unknown future state of significantly different conditions. In addition, climate change, biodiversity loss and phosphorus production were already transgressed by humanity and require innovative frameworks and effective solutions.


Global Conservation Of Biodiversity And Ecosystem Services, Will R. Turner, Katrina Brandon, Thomas M. Brooks, Robert Costanza Nov 2007

Global Conservation Of Biodiversity And Ecosystem Services, Will R. Turner, Katrina Brandon, Thomas M. Brooks, Robert Costanza

Habitat destruction has driven much of the current biodiversity extinction crisis, and it compromises the essential benefits, or ecosystem services, that humans derive from functioning ecosystems. Securing both species and ecosystem services might be accomplished with common solutions. Yet it is unknown whether these two major conservation objectives coincide broadly enough worldwide to enable global strategies for both goals to gain synergy. In this article, we assess the concordance between these two objectives, explore how the concordance varies across different regions, and examine the global potential for safeguarding biodiversity and ecosystem services simultaneously. We find that published global priority maps …

There has been increasing demand for rigorous methods for evaluating biodiversity, one of the ecosystem services that sustains and fulfills human life. After carefully examining the literature, we found three key points that should be taken into account when we evaluate biodiversity. The first point is that any "indicator species" tends to be a leaky target of biodiversity. The second point is that "buffering" that is useful for representing the ecological concept of boundaries should have scientific meanings. The third point is that a "watershed" that integrates most natural processes is advantageous as the spatial range for evaluation. Based on …
