Catastrophic Declines in Wilderness Areas Undermine Global Environment Targets

Humans have altered terrestrial ecosystems for millennia [1], yet wilderness areas still remain as vital refugia where natural ecological and evolutionary processes operate with minimal human disturbance [2-4], underpinning key regional- and planetary-scale functions [5, 6]. Despite the myriad values of wilderness areas-as critical strongholds for endangered biodiversity [7], for carbon storage...

The Macroeconomic Cost of Catastrophic Pollinator Declines

A computable general equilibrium (CGE) approach is used to assess the macroeconomic effects of global and regional catastrophic losses of pollination ecosystem services. Results show economic risks to both direct crop sectors and indirect non-crop sectors in the economy, with a substantial amount of regional heterogeneity. In addition, there exists potential for winners, those regions with a co...

Clustered Networks Protect Cooperation Against Catastrophic Collapse

Assuming a society of conditional cooperators (or moody conditional cooperators), this computational study proposes a new perspective on the structural advantage of social network clustering. Previous work focused on how clustered structure might encourage initial outbreaks of cooperation or defend against invasion by a few defectors. Instead, we explore the ability of a societal structure to r...

Reducing Global Catastrophic Biological Risks

Reducing global catastrophic risks (GCRs) is one of our top priorities at the Open Philanthropy Project. We have a particular interest in addressing GCRs from biological sources—or global catastrophic biological risks (GCBRs), to use the term coined by the Johns Hopkins Center for Health Security. As we build our new biosecurity and pandemic preparedness (BPP) program, we’re putting a lot of th...

Global biodiversity: indicators of recent declines.

In 2002, world leaders committed, through the Convention on Biological Diversity, to achieve a significant reduction in the rate of biodiversity loss by 2010. We compiled 31 indicators to report on progress toward this target. Most indicators of the state of biodiversity (covering species' population trends, extinction risk, habitat extent and condition, and community composition) showed declin...
