Contribution of citizen science towards international biodiversity monitoring

Biological Conservation, Год журнала: 2016, Номер 213, С. 280 - 294

To meet collective obligations towards biodiversity conservation and monitoring, it is essential that the world's governments non-governmental organisations as well research community tap all possible sources of data information, including new, fast-growing such citizen science (CS), in which volunteers participate some or aspects environmental assessments. Through compilation a database on CS community-based monitoring (CBM, subset CS) programs, we assess where contributions from CBM are significant opportunities for growth exist. We use Essential Biodiversity Variable framework to describe range needed track progress global targets, strengths gaps geographical taxonomic coverage. Our results show existing particularly provide large-scale species distribution population abundance, traits phenology, ecosystem function variables primary secondary productivity. Only birds, Lepidoptera plants monitored at scale. Most schemes found Europe, North America, South Africa, India, Australia. then explore what can be learned successful CS/CBM programs would facilitate scaling up current efforts, how coverage better exploited, strategies could maximise synergies between other approaches biodiversity, particular remote sensing. More targeted funding will needed, if contribute further international monitoring.

Agricultural insecticides threaten surface waters at the global scale

Proceedings of the National Academy of Sciences, Год журнала: 2015, Номер 112(18), С. 5750 - 5755

Compared with nutrient levels and habitat degradation, the importance of agricultural pesticides in surface water may have been underestimated due to a lack comprehensive quantitative analysis. Increasing pesticide contamination results decreasing regional aquatic biodiversity, i.e., macroinvertebrate family richness is reduced by ∼30% at concentrations equaling legally accepted regulatory threshold (RTLs). This study provides metaanalysis 838 peer-reviewed studies (>2,500 sites 73 countries) that evaluates, for first time our knowledge on global scale, exposure waters particularly toxic insecticides. We tested whether measured insecticide (MICs; quantified concentrations) exceed their RTLs how risks depend development over stringency environmental regulation. Our analysis reveals MICs occur rarely (i.e., an estimated 97.4% analyses conducted found no MICs) there complete scientific monitoring data ∼90% cropland. Most importantly, 11,300 MICs, 52.4% (5,915 cases; 68.5% sites) exceeded RTL either (RTLSW) or sediments. Thus, biological integrity resources substantial risk. RTLSW exceedances catchment size, sampling regime, date; are significantly higher newer-generation insecticides pyrethroids); high even countries stringent regulations. These suggest need worldwide improvements current regulations application practices intensified research efforts presence effects under real-world conditions.

The interaction of human population, food production, and biodiversity protection

Science, Год журнала: 2017, Номер 356(6335), С. 260 - 264

Research suggests that the scale of human population and current pace its growth contribute substantially to loss biological diversity. Although technological change unequal consumption inextricably mingle with demographic impacts on environment, needs all beings-especially for food-imply projected will undermine protection natural world. Numerous solutions have been proposed boost food production while protecting biodiversity, but alone these proposals are unlikely staunch biodiversity loss. An important approach sustaining well-being is through actions can slow eventually reverse growth: investing in universal access reproductive health services contraceptive technologies, advancing women's education, achieving gender equality.
