Managing biological invasions: the cost of inaction

Biological Invasions, Год журнала: 2022, Номер 24(7), С. 1927 - 1946

Опубликована: Март 18, 2022

Abstract Ecological and socioeconomic impacts from biological invasions are rapidly escalating worldwide. While effective management underpins impact mitigation, such actions often delayed, insufficient or entirely absent. Presently, delays emanate a lack of monetary rationale to invest at early invasion stages, which precludes prevention eradication. Here, we provide by developing conceptual model quantify the cost inaction, i.e., additional expenditure due delayed management, under varying time efficiencies. Further, apply damage data relatively data-rich genus ( Aedes mosquitoes). Our demonstrates that rapid interventions following drastically minimise costs. We also identify key points in differentiate among scenarios timely, severely intervention. Any action during phase results substantial losses $$( > 50\%$$ (>50% potential maximum loss). For spp., estimate existing delay 55 years led an total approximately $ 4.57 billion (14% cost), compared scenario with only seven prior (< 1% cost). Moreover, absence action, long-term would have accumulated US$ 32.31 billion, more than times observed inaction cost. These highlight need for timely invasive alien species—either pre-invasion, as soon possible after detection—by demonstrating how investments reduce economic impacts.

Abstract Invasive ants are amongst the most destructive and widespread invaders across globe; they can strongly alter invaded ecosystems responsible for loss of native ant species. Several studies have reported that invasive also lead to substantial economic costs. In this study, we search, describe analyse 1342 costs compiled in InvaCost database. Economic costs, since 1930 12 species 27 countries, totalled US$ 51.93 billion, from which 10.95 billion were incurred, 40.98 potential (i.e., expected or predicted costs). More than 80% total associated with only two species, Solenopsis invicta Wasmannia auropunctata ; USA Australia. Overall, damage amounted 92% cost, mainly impacting agriculture, public social welfare sectors. Management primarily post-invasion management (US$ 1.79 billion), much lower amounts dedicated prevention 235.63 million). Besides taxonomic bias, cost information was lacking an average 78% countries. Moreover, even countries where reported, such available 56% locations. Our synthesis suggests global massive but largely biased towards developed economies, a huge proportion underreported thus likely grossly underestimated. We advocate more improved reporting through better collaborations between managers, practitioners researchers, crucial basis adequately informing future budgets improving proactive actions ants.

Biological invasions are as costly as natural hazards

Perspectives in Ecology and Conservation, Год журнала: 2023, Номер 21(2), С. 143 - 150

Опубликована: Март 29, 2023

Natural hazards — such as storms, floods, and wildfires can be disastrous phenomena so biological invasions, for which impacts are often irrevocable insidious. Yet, invasion awareness remains low compared to natural hazards, investments manage invasions remain vastly underfunded delayed. Here, we quantified costs relative raise political leverage. Analysing damage cost data over 1980–2019, economic losses from were of similar magnitude (e.g., $1,208.0 bn against $1,913.6 storms $1,139.4 earthquakes). Alarmingly, increased faster than time. Similar impact magnitudes growth rates urge commensurate recognition, coordination action towards in policies.

ABSTRACT Standardised terminology in science is important for clarity of interpretation and communication. In invasion – a dynamic rapidly evolving discipline the proliferation technical has lacked standardised framework its development. The result convoluted inconsistent usage terminology, with various discrepancies descriptions damage interventions. A therefore needed clear, universally applicable, consistent to promote more effective communication across researchers, stakeholders, policymakers. Inconsistencies stem from exponential increase scientific publications on patterns processes biological invasions authored by experts disciplines countries since 1990s, as well legislators policymakers focusing practical applications, regulations, management resources. Aligning standardising stakeholders remains challenge science. Here, we review evaluate multiple terms used (e.g. ‘non‐native’, ‘alien’, ‘invasive’ or ‘invader’, ‘exotic’, ‘non‐indigenous’, ‘naturalised’, ‘pest’) propose simplified terminology. streamlined translate into 28 other languages based ( i ) denoting species transported beyond their natural biogeographic range, ii ‘established non‐native’, i.e. those non‐native that have established self‐sustaining populations new location(s) wild, iii ‘invasive non‐native’ recently spread are spreading invaded range actively passively without human mediation. We also highlight importance conceptualising ‘spread’ classifying invasiveness ‘impact’ management. Finally, protocol dispersal mechanism, origin, population status, iv impact.

Invasive Aedes aegypti and albopictus mosquitoes transmit viruses such as dengue, chikungunya Zika, posing a huge public health burden well having less understood economic impact. We present comprehensive, global-scale synthesis of studies reporting these costs, spanning 166 countries territories over 45 years. The minimum cumulative reported cost estimate expressed in 2022 US$ was 94.7 billion, although this figure reflects considerable underreporting underestimation. analysis suggests 14-fold increase with an average annual expenditure 3.1 maximum 20.3 billion 2013. Damage losses were order magnitude higher than investment management, only modest portion allocated to prevention. Effective control measures are urgently needed safeguard global well-being, reduce the on human societies. This study fills critical gap by addressing increasing costs Aedes-borne diseases offers insights inform evidence-based policy.

Globalization has led to the introduction of thousands alien species worldwide. With growing impacts by invasive species, understanding invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, dynamics have been assumed follow an "invasion curve" (S-shaped curve available area invaded over time), but this dynamic lacked empirical testing using large-scale data neglects consider invader abundances. We propose "impact describing generated time based on cumulative To test curve's applicability, we used data-rich New Zealand mud snail Potamopyrgus antipodarum, one most damaging freshwater invaders that almost all Europe. Using long-term (1979-2020) abundance environmental collected across 306 European sites, observed P. antipodarum generally increased through time, with slower population growth at higher latitudes lower runoff depth. Fifty-nine percent these populations followed impact curve, characterized first occurrence, exponential growth, then saturation. This behaviour is consistent boom-bust dynamics, as saturation occurs due a rapid decline in time. Across estimated peaked approximately two decades after detection, rate progression along was influenced local abiotic conditions. The S-shaped may be common among many undergo complex dynamics. provides potentially unifying approach advance could inform timely management actions mitigate ecosystems economies.

The economic and environmental threats posed by non-native forest insects are ever increasing with the continuing globalization of trade travel; thus, need for mitigation through effective biosecurity is greater than ever. However, despite decades research implementation preborder, border, postborder preventative measures, insect invasions continue to occur, no evidence saturation, even predicted accelerate.

Abstract Background Biological invasions threaten the functioning of ecosystems, biodiversity, and human well-being by degrading ecosystem services eliciting massive economic costs. The European Union has historically been a hub for cultural development global trade, thus, extensive opportunities introduction spread alien species. While reported costs biological to some member states have recently assessed, ongoing knowledge gaps in taxonomic spatio-temporal data suggest that these were considerably underestimated. Results We used latest available cost InvaCost (v4.1)—the most comprehensive database on invasions—to assess magnitude this underestimation within via projections current future invasion macroeconomic scaling temporal modelling approaches project information over taxa, space, time, thereby producing more complete estimate economy. identified only 259 out 13,331 (~ 1%) known invasive species Union.
