Global human population has surpassed Earth’s sustainable carrying capacity
Open AccessCorey J A Bradshaw, Melinda A Judge et al.ARTICLEEnvironmental Research Letters2026
The ecological concept of human carrying capacity is necessarily complicated because human beings are the ‘ultimate ecosystem engineers’ who moderate the environment for their benefit. For at least the last few hundred years, human ingenuity, access to massive stocks of fossil fuels, and technological development have driven facilitation whereby increasing human abundance has promoted higher population growth rates. However, this positive relatio…
Climate change policies fail to protect child health
Open AccessJhermayne Ubalde, Corey J A Bradshaw et al.ARTICLEGlobalization and Health2025
National policies are essential for countries to adapt to the negative health impacts of climate change. Children are disproportionately affected by these impacts and must be at the heart of adaptation policies to address their vulnerabilities. Adaptation commitments worldwide are integrated into national adaptation plans, nationally determined contributions, national communications, and other multisectoral policies. We aimed to evaluate how effe…
Systematic review and meta-analysis of studies testing the efficacy of shark-bite mitigation
Open AccessMadeline Riley, Corey J A Bradshaw et al.ARTICLEMarine Policy2025
1. The development and scientific testing of shark-bite mitigation measures are increasing, but unstandardised testing impedes our ability to compare their efficacy. 2. We did a systematic review and meta-analysis to summarise efficacy using qualitative and quantitative approaches. 3. We reviewed 67 papers testing 114 measures across three mitigation types (area/personal/injury reduction). Measures to protect areas were the most tested ( n = 64),…
Net benefit of smaller human populations to environmental integrity and individual health and wellbeing
Open AccessChitra Maharani Saraswati, Melinda A Judge et al.ARTICLEFrontiers in Public Health2024
Introduction: The global human population is still growing such that our collective enterprise is driving environmental catastrophe. Despite a decline in average population growth rate, we are still experiencing the highest annual increase of global human population size in the history of our species-averaging an additional 84 million people per year since 1990. No review to date has accumulated the available evidence describing the associations …

Directionally supervised cellular automaton for the initial peopling of Sahul
Corey J A Bradshaw, Stefani A Crabtree et al.PREPRINT2022References: 26
Reconstructing the patterns of expansion out of Africa and across the globe by modern Homo sapiens have been advanced using demographic and travel-cost models. However, modelled routes are ipso facto influenced by migration rates, and vice versa. It is therefore timely to combine these two intertwined phenomena in reconstructing the migratory history of our species. We applied such an approach to one of the world’s earliest peopling events in Sah…
Underestimating the Challenges of Avoiding a Ghastly Future
Open AccessCorey J A Bradshaw, P R Ehrlich et al.ARTICLEFrontiers in Conservation Science2021
We report three major and confronting environmental issues that have received little attention and require urgent action. First, we review the evidence that future environmental conditions will be far more dangerous than currently believed. The scale of the threats to the biosphere and all its lifeforms—including humanity—is in fact so great that it is difficult to grasp for even well-informed experts. Second, we ask what political or economic sy…

The First Australians grew to a population of millions, much more than previous estimates
Corey J A Bradshaw, Corey Bradshaw et al.PREPRINT2021References: 1
We know it is more than 60,000 years since the first people entered the continent of Sahul — the giant landmass that connected New Guinea, Australia and Tasmania when sea levels were lower than today. But where the earliest people moved across the landscape, how fast they moved, and how many were involved, have been shrouded in mystery. Our latest research, published today shows the establishment of populations in every part of this giant contine…
Landscape rules predict optimal superhighways for the first peopling of Sahul
Open AccessStefani A Crabtree, Devin A White et al.ARTICLENature Human Behaviour2021Cited by: 29References: 80
Archaeological data and demographic modelling suggest that the peopling of Sahul required substantial populations, occurred rapidly within a few thousand years and encompassed environments ranging from hyper-arid deserts to temperate uplands and tropical rainforests. How this migration occurred and how humans responded to the physical environments they encountered have, however, remained largely speculative. By constructing a high-resolution digi…
Implications of Australia's Population Policy for Future Greenhouse Gas Emissions Targets
Open AccessCorey J A Bradshaw, B W BrooksARTICLEAsia & the Pacific Policy Studies2016References: 5
Australia's high per capita emissions rates makes it is a major emitter of anthropogenic greenhouse gases, but its low intrinsic growth rate means that future increases in population size will be dictated by net overseas immigration. We constructed matrix models and projected the population to 2100 under six different immigration scenarios. A constant 1 per cent proportional immigration scenario would result in 53 million people by 2100, producin…

Global evidence that deforestation amplifies flood risk and severity in the developing world
Open AccessCorey J A Bradshaw, Navjot S Sodhi et al.ARTICLEGlobal Change Biology2007
With the wide acceptance of forest‐protection policies in the developing world comes a requirement for clear demonstrations of how deforestation may erode human well‐being and economies. For centuries, it has been believed that forests provide protection against flooding. However, such claims have given rise to a heated polemic, and broad‐scale quantitative evidence of the possible role of forests in flood protection has not been forthcoming. Usi…
Strength of Evidence for Density Dependence in Abundance Time Series of 1198 Species
Open AccessB W Brooks, Barry W Brook et al.ARTICLEEcology2006
Population limitation is a fundamental tenet of ecology, but the relative roles of exogenous and endogenous mechanisms remain unquantified for most species. Here we used multi-model inference (MMI), a form of model averaging, based on information theory (Akaike's Information Criterion) to evaluate the relative strength of evidence for density-dependent and density-independent population dynamical models in long-term abundance time series of 1198 …
