    Abstract Biodiversity in ecosystems plays an important role in supporting human welfare, including regulating the transmission of infectious diseases. Many of these services are not fully-appreciated due to complex environmental dynamics and lack of baseline data. Multicontinental amphibian decline due to the fungal pathogen Batrachochytrium dendrobatidis (Bd) provides a stark example. Even though amphibians are known to affect natural food webs—including mosquitoes that transmit human diseases—the human health impacts connected to their massive decline have received little attention. Here we leverage a unique ensemble of ecological surveys, satellite data, and newly digitized public health records to show an empirical link between a wave of Bd-driven collapse of amphibians in Costa Rica and Panama and increased human malaria incidence. Subsequent to the estimated date of Bd-driven amphibian decline in each ‘county’ (canton or distrito), we find that malaria cases are significantly elevated for several years. For the six year peak of the estimated effect, the annual expected county-level increase in malaria ranges from 0.76 to 1.1 additional cases per 1000 population. This is a substantial increase given that cases country-wide per 1000 population peaked during the timeframe of our study at approximately 1.5 for Costa Rica and 1.1 for Panama. This previously unidentified impact of biodiversity loss illustrates the often hidden human welfare costs of conservation failures. These findings also show the importance of mitigating international trade-driven spread of similar emergent pathogens like Batrachochytrium salamandrivorans .

  2. Article ; Online: Social distancing responses to COVID-19 emergency declarations strongly differentiated by income.

    Abstract In the absence of a vaccine, social distancing measures are one of the primary tools to reduce the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, which causes coronavirus disease 2019 (COVID-19). We show that social distancing following US state-level emergency declarations substantially varies by income. Using mobility measures derived from mobile device location pings, we find that wealthier areas decreased mobility significantly more than poorer areas, and this general pattern holds across income quantiles, data sources, and mobility measures. Using an event study design focusing on behavior subsequent to state emergency orders, we document a reversal in the ordering of social distancing by income: Wealthy areas went from most mobile before the pandemic to least mobile, while, for multiple measures, the poorest areas went from least mobile to most. Previous research has shown that lower income communities have higher levels of preexisting health conditions and lower access to healthcare. Combining this with our core finding-that lower income communities exhibit less social distancing-suggests a double burden of the COVID-19 pandemic with stark distributional implications.

    Abstract Pollution from wildfires constitutes a growing source of poor air quality globally. To protect health, governments largely rely on citizens to limit their own wildfire smoke exposures, but the effectiveness of this strategy is hard to observe. Using data from private pollution sensors, cell phones, social media posts and internet search activity, we find that during large wildfire smoke events, individuals in wealthy locations increasingly search for information about air quality and health protection, stay at home more and are unhappier. Residents of lower-income neighbourhoods exhibit similar patterns in searches for air quality information but not for health protection, spend less time at home and have more muted sentiment responses. During smoke events, indoor particulate matter (PM<sub>2.5</sub>) concentrations often remain 3-4× above health-based guidelines and vary by 20× between neighbouring households. Our results suggest that policy reliance on self-protection to mitigate smoke health risks will have modest and unequal benefits.

    Abstract If individuals have spatially differentiated preferences for sites or areas impacted by an invasive alien species, effective management must take this heterogeneity into account and target sites or areas accordingly. In this paper, we estimate spatially differentiated preferences for the management of primrose willow (Ludwigia grandiflora), an invasive weed spreading in a French regional park. We use an original spatially explicit discrete choice experiment to evaluate individuals’ willingness to pay (WTP) to control the invasion in different areas of the regional park. Our results indicate that WTP for management highly depends on the area considered, with areas where it is three times higher than others. We analyze the main factors explaining the heterogeneity of preferences and show that the closer respondents live to the park, the more they visit and/or practice activities in it, the higher their WTP and spatial preferences. Park residents and regular users have high WTP and unambiguous preferences for targeting control to specific areas. Non-residents and occasional users have much lower WTP and more homogeneous spatial preferences. These results suggest that implementing management strategies that spatially target invasion control according to public preferences is likely to produce significant utility gains. These gains are all the more important as the preferences taken into account are those of the stakeholders directly concerned by the invasion, the residents and regular park users. Ignoring these spatial preferences will lead to sub-optimal invasion management.

    Abstract Biological invasions entail massive biodiversity losses and tremendous economic impacts that justify significant management efforts. Because the funds available to control biological invasions are limited, there is a need to identify priority species. In this paper, we first review current invasive species prioritization methods and explicitly highlight their strengths and pitfalls. We then construct a cost–benefit optimization framework that offers the theoretical foundations of a simple method for the management of multiple invasive species under a limited budget. We provide an algorithm to operationalize this framework and render explicit the assumptions required to satisfy the management objective.

    Abstract The number of biological invasions increases and so are the impacts these species cause to the environment and the economy. Because resources are limited, the funds available for the management of biological invasions need to be allocated in the most efficient way. Applying a cost/benefit approach incorporating species utility, distinctiveness, robustness of species and their interactions, this paper provides with an operational optimal method for setting management priorities under a limited budget constraint.
