Use of demand for and spatial flow of ecosystem services to identify priority areas
Policies and research increasingly focus on the protection of ecosystem services (ESs) through priority-area conservation. Priority areas for ESs should be identified based on ES capacity and ES demand and account for the connections between areas of ES capacity and demand (flow) resulting in areas of unique demand-supply connections (flow zones). We tested ways to account for ES demand and flow zones to identify priority areas in the European Union. We mapped the capacity and demand of a global (carbon sequestration), a regional (flood regulation), and 3 local ESs (air quality, pollination, and urban leisure). We used Zonation software to identify priority areas for ESs based on 6 tests: with and without accounting for ES demand and 4 tests that accounted for the effect of ES flow zone. There was only 37.1% overlap between the 25% of priority areas that encompassed the most ESs with and without accounting for ES demand. The level of ESs maintained in the priority areas increased from 23.2% to 57.9% after accounting for ES demand, especially for ESs with a small flow zone. Accounting for flow zone had a small effect on the location of priority areas and level of ESs maintained but resulted in fewer flow zones without ES maintained relative to ignoring flow zones. Accounting for demand and flow zones enhanced representation and distribution of ESs with local to regional flow zones without large trade-offs relative to the global ES. We found that ignoring ES demand led to the identification of priority areas in remote regions where benefits from ES capacity to society were small. Incorporating ESs in conservation planning should therefore always account for ES demand to identify an effective priority network for ESs.Peer reviewe
Methodology and applications of city level CO2 emission accounts in China
China is the world's largest energy consumer and CO2 emitter. Cities contribute 85% of the total CO2 emissions in China and thus are considered as the key areas for implementing policies designed for climate change adaption and CO2 emission mitigation. However, the emission inventory construction of Chinese cities has not been well researched, mainly owing to the lack of systematic statistics and poor data quality. Focusing on this research gap, we developed a set of methods for constructing CO2 emissions inventories for Chinese cities based on energy balance table. The newly constructed emission inventory is compiled in terms of the definition provided by the IPCC territorial emission accounting approach and covers 47 socioeconomic sectors, 17 fossil fuels and 9 primary industry products, which is corresponding with the national and provincial inventory. In the study, we applied the methods to compile CO2 emissions inventories for 24 common Chinese cities and examined uncertainties of the inventories. Understanding the emissions sources in Chinese cities is the basis for many climate policy and goal research in the future
Informed recruitment in partner studies of HIV transmission: an ethical issue in couples research
An international network (PlaNet) to evaluate a human placental testing platform for chemicals safety testing in pregnancy
tThe human placenta is a critical life-support system that nourishes and protects a rapidly growing fetus; aunique organ, species specific in structure and function. We consider the pressing challenge of providingadditional advice on the safety of prescription medicines and environmental exposures in pregnancy andhow ex vivo and in vitro human placental models might be advanced to reproducible human placentaltest systems (HPTSs), refining a weight of evidence to the guidance given around compound risk assess-ment during pregnancy. The placental pharmacokinetics of xenobiotic transfer, dysregulated placentalfunction in pregnancy-related pathologies and influx/efflux transporter polymorphisms are a few caveatsthat could be addressed by HPTSs, not the specific focus of current mammalian reproductive toxicologysystems. An international consortium, “PlaNet”, will bridge academia, industry and regulators to con-sider screen ability and standardisation issues surrounding these models, with proven reproducibilityfor introduction into industrial and clinical practice
The Politics of Method: Taming the New, Making Data Official
Statisticians are under pressure to innovate, partly due to shrinking budgets and the call to do more with less, but also due to technological advances and emergence of new actors promising to produce more accurate and timely statistics with what has come to be known as “big data”. This raises the question, how do new forms of data and methods become legitimate and official? We approach this question by conceiving of official statistics as part of a transnational field in which different factions of actors compete and struggle over the authority to innovate the data and methods that are legitimated to produce official statistics. We consider these struggles as a politics of method that is not reducible to a competition between ideas and words. They are also material insofar as they feature competing digital devices mobilised to demonstrate the validity of new data and methods. Through two empirical examples, we identify the strategy of reassembling methods to capture how statisticians tame and contain innovations based on big data, especially those introduced by data scientists, by integrating and simultaneously subordinating them to existing methods. By doing so, we suggest that reassembling is an innovation strategy that secures the relative position of national and international statisticians within the transnational field of statistics
