The science and management of infectious disease are entering a new stage. Increasingly public policy to manage epidemics focuses on motivating people, through social distancing policies, alter their behavior reduce contacts risk. Person-to-person drive human dynamics. People value such willing accept some risk gain contact-related benefits. cost–benefit trade-offs that shape contact behavior, hence the course epidemics, often only implicitly incorporated in epidemiological models. This...
In the absence of a vaccine, social distancing measures are one primary tools to reduce transmission severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, which causes disease 2019 (COVID-19). We show that following US state-level emergency declarations substantially varies by income. Using mobility derived from mobile device location pings, we find wealthier areas decreased significantly more than poorer areas, and this general pattern holds across income quantiles, data...
Climate-smart agriculture (CSA) addresses the challenge of meeting growing demand for food, fibre and fuel, despite changing climate fewer opportunities agricultural expansion on additional lands. CSA focuses contributing to economic development, poverty reduction food security; maintaining enhancing productivity resilience natural ecosystem functions, thus building capital; reducing trade-offs involved in these goals. Current gaps knowledge, work within CSA, agendas interdisciplinary...
Abstract Understanding the likely future impacts of biological invasions is crucial yet highly challenging given multiple relevant environmental, socio‐economic and societal contexts drivers. In absence quantitative models, methods based on expert knowledge are best option for assessing invasion trajectories. Here, we present an assessment drivers potential alien species under contrasting scenarios socioecological through mid‐21st century. Based responses from 36 experts in invasions,...
Significance Vaccines are a key intervention to reduce the burden of COVID-19 pandemic. However, vaccine supply and administration capacity will initially be limited. Due these constraints, it is critical understand how deployment can targeted minimize overall disease. In this paper, we solve for optimal dynamic strategies allocate limited vaccines over population differentiated by age essential worker status that minimizes number total deaths, years life lost, or infections. We find older...
Mathematical epidemiology, one of the oldest and richest areas in mathematical biology, has significantly enhanced our understanding how pathogens emerge, evolve, spread. Classical epidemiological models, standard for predicting managing spread infectious disease, assume that contacts between susceptible individuals depend on their relative frequency population. The behavioral factors underpin contact rates are not generally addressed. There is, however, an emerging a class models addresses...
Abstract Multiple promising COVID-19 vaccines are under rapid development, with deployment of the initial supply expected by 2021. Careful design a vaccine prioritization strategy across socio-demographic groups is an imminent and crucial public policy challenge given that (1) eventual will be highly constrained for at least first several months vaccination campaign, (2) there stark differences in transmission severity impacts from SARS-CoV-2 groups. Previous experience development...
Abstract Scenario analysis has emerged as a key tool to analyze complex and uncertain future socio-ecological developments. However, currently existing global scenarios (narratives of how the world may develop) have neglected biological invasions, major threat biodiversity economy. Here, we use novel participatory process develop diverse set invasion spanning wide range plausible futures through 2050. We adapted widely used “two axes” scenario approach four families each, resulting in 16...
Abstract Biodiversity in ecosystems plays an important role supporting human welfare, including regulating the transmission of infectious diseases. Many these services are not fully-appreciated due to complex environmental dynamics and lack baseline data. Multicontinental amphibian decline fungal pathogen Batrachochytrium dendrobatidis (Bd) provides a stark example. Even though amphibians known affect natural food webs—including mosquitoes that transmit diseases—the health impacts connected...
Theory suggests that individual behavioral responses impact the spread of flu-like illnesses, but this has been difficult to empirically characterize. Social distancing is an important component response, though analyses have limited by a lack data. Our objective use media data characterize social behavior in order inform explanatory and predictive epidemiological models. We on variation home television viewing as proxy for time spent and, extension, contact. This imperfect appealing since...
International trade is a key pathway for the global spread of nonnative species. Historical and emerging flows interact with ecological dynamics to shape species risk determine how that can be mitigated. This article discusses these underlying processes, trends, role past future economics research in understanding managing risks from trade. We identify four priorities research. These include expanding economic analysis consider interventions across biosecurity continuum more comprehensively,...
Using a bioeconomic model of coral reef-mangrove-seagrass system, we analyze the dynamic path incentives to achieve an efficient transition steady state levels fish biomass and mangrove habitat conservation. Our nests different types species dependency allows for changes in extent affect growth rate long-run level. We solve two-control, two-state non-linear optimal control problem numerically compute input efficiency frontier characterizing tradeoff between population. After identifying...
Many non-native insect establishments are undetected—across regions, this estimated “establishment debt” ranges from 10 to 52%.
Invasive non‐native species cause enormous economic damage. Although there is both regulative and legislative precedent for policies restricting introduction of potentially invasive species, lack a unified theory invasions—particularly with respect to plants—has impeded efforts implement screening despite empirical patterns suggesting the existence “invasion syndromes”. Motivated by recent advances in comparative biology we sought develop cost‐sensitive model that would associate groups...
For reducing greenhouse gas emissions, intensity targets are attracting interest as a flexible mechanism that would better allow for economic growth than emissions caps. the same expected however, responses to unexpected productivity shocks differ. Using real business cycle model, we find cap dampens effects of in economy on all variables except shadow value constraint. An tax leads outcomes but with greater volatility. Certainty-equivalent maintain higher levels labor, capital, and output...
International trade in plants and animals generates significant economic benefits. It also leads to substantial unintended impacts when introduced species become invasive, causing environmental disturbance or transmitting diseases that affect people, livestock, other wildlife the environment. Policy responses are usually only implemented after these established damages already incurred. agreements control likewise based on selection of with known impacts. We aim further develop quantitative...
Abstract International trade in nonnative species generates economic benefits but also introduces many harmful invasive species. Recent advances screening tools enable useful predictions of invasiveness which can be combined with estimates impacts to effectively manage the trade‐off between and costs this trade. Despite this, most countries maintain an essentially “open door” policy where almost all are allowed for introduction until they prove problematic. This approach implicitly favors...
