Riverine Habitats

Caprimulgus affinis is an endemic species commonly known as the Taiwan nighthawk, forest nighthawk, or South Asian nighthawk. In recent years, the C. affinis population has gradually moved outward from river habitats into the metropolitan areas of Taiwan. Because male birds’ booming sounds at night can reach up to 90 dB or higher and they can be intermittently tweeting for more than 10 hours, they often disturb the sleep of urban residents and can even cause nightmares. In this study, we analyzed long-term survey data to assess the distribution history of C. affinis in Taiwan. By using 1738 entries of observation data collected from 1999 to 2014, a model of C. affinis distribution was constructed, and a geostatistical method was used to improve the accuracy of the model estimate. In addition, the Mann–Kendall trend test was applied to predict future C. affinis distribution. Based on the results, four variables were selected to construct the C. affinis distribution matrix. Urban population, coastal proximity, and distance to upstream river location represented positive driving forces, whereas city elevation was a negative driving force. C. affinis is currently distributed on the plains of central and southern Taiwan and in eastern Taiwan. The C. affinis emergence trend diagram was plotted using the time–space trend diagram, which showed yearly increases in the C. affinis populations in urban and settled areas including central, western, northeastern, and southeastern Taiwan and yearly decreases in the populations in rural areas including northern and southern Taiwan, especially in fragmented riverine habitats. Regression kriging can correctly describe the distribution of the entire C. affinis population, which leads to the correct understanding of the biological corridor of C. affinis in their migration through the graphical contours in GIS. The analytic model in this study contributes to the establishment of the time–space trend diagram.

Abstract. To investigate the physico-chemical properties of aerosols in Taiwan, an observation network was initiated in 2003. In this work, the measurements of the mass concentration and carbonaceous composition of PM10 and PM2.5 are presented. Analysis on the data collected in the first 5-years, from 2003 to 2007, showed that there was a very strong contrast in the aerosol concentration and composition between the rural and the urban/suburban stations. The five-year means of EC at the respective stations ranged from 0.9±0.04 to 4.2±0.1 μgC m−3. In rural areas, EC accounted for 2–3% of PM10 and 3–5% of PM2.5 mass loadings, comparing to 4–6% of PM10 and 4–8% of PM2.5 in the urban areas. It was found that the spatial distribution of EC was consistent with CO and NOx across the network stations, suggesting that the levels of EC over Taiwan were dominated by local sources. The measured OC was split into POC and SOC counterparts following the EC tracer method. Five-year means of POC ranged from 1.8±0.1 to 9.7±0.2 μgC m−3 among the stations. It was estimated that the POM contributed 5–17% of PM10 and 7–18% of PM2.5 in Taiwan. On the other hand, the five-year means of SOC ranged from 1.5±0.1 to 3.8±.3 μgC m−3. The mass fractions of SOM were estimated to be 9–19% in PM10 and 14–22% in PM2.5. The results showed that the SOC did not exhibit significant urban-rural contrast as did the POC and EC. A significant cross-station correlation between SOC and total oxidant was observed, which means the spatial distribution of SOC in Taiwan was dominated by the oxidant mixing ratio. Besides, correlation was also found between SOC and particulate nitrate, implying that the precursors of SOA were mainly from local anthropogenic sources. In addition to the spatial distribution, the carbonaceous aerosols also exhibited distinct seasonality. In northern Taiwan, the concentrations of all the three carbonaceous components (EC, POC, and SOC) reached their respective minima in the fall season. POC and EC increased drastically in winter and peaked in spring, whereas the SOC was characterized by a bimodal pattern with the maximal concentration in winter and a second mode in summertime. In southern Taiwan, minimal levels of POC and EC occurred consistently in summer and the maxima were observed in winter, whereas the SOC peaked in summer and declined in wintertime. The discrepancies in the seasonality of carbonaceous aerosols between northern and southern Taiwan were most likely caused by the seasonal meteorological settings that dominated the dispersion of air pollutants. Moreover, it was inferred that the Asian pollution outbreaks could have shifted the seasonal maxima of air pollutants from winter to spring in the northern Taiwan, and that the increases in biogenic SOA precursors and the enhancement in SOA yield were responsible for the elevated SOC concentrations in summer.

A lack of transport opportunities has been shown to be a barrier for accessibility and social inclusion in contemporary society. In rural and sparsely populated areas, access to public transport is often poor compared to urban areas, leading to fewer possibilities to participate in normal relationships and activities among rural dwellers. Based on qualitative interviews with rural dwellers in Sweden, the aim of this study was to explore how access to transport can meet the needs of mobility and activity participation in everyday life and how different modes of transport are being used. The study has been permeated by the time-geographical perspective, which considers people’s use of time and space and the restrictions they face in order to carry out activities, including travel. The results show that travel by private car plays a central role in realizing everyday activities for rural dwellers, as well as a perception of the car as being the norm in contemporary society. Frequent car use is the consequence of a combination of time-space restrictions, habit, and a lack of services, activities, and public transport in rural areas. Poor public transport services limit children’s and adolescents’ independent mobility in particular. Further, the physical environment influences the ability to use public transport, for example if roads and bus stops are seen as unsafe. Based on the results of the study, several measures and improvements are proposed that could increase mobility and accessibility in rural areas and reduce car dependency.

AbstractObjective:To understand methodological concerns related to dietary intake collection in transitional societies.Design:Three days of household weighing and measurement of all food used and repeated 24-hour recalls.Setting:Eight Chinese provinces.Subjects:Five thousand nine hundred and fifty-two and 5152 adults aged 20–45 years in 1989 and 1997, respectively.Results:Great variance exists in the types and quantity of animal products used in common recipes. For example, the proportion of pork from lean cuts in ‘stir-fried fresh pepper and pork’ varies between 14 and 24% in urban and rural areas and the total pork content for 100 g (dish) varies by 15 to 19 g between rural and urban areas in each of eight provinces. Another challenge relates to the variation in the edible vegetable oil content added during food preparation. Reliance on standard recipes for each fried dish would miss the variations in oil use over time, space and socio-economic status.Conclusions:Dietary change is rapid in transitional countries. Reliance on recipes standardised for animal food and edible oil contents will lead to very large systematic errors in the measurement of energy, fat and protein intakes.

Abstract. Autonomous subsidence plays a major role in the landscape of the western parts of the Netherlands. For a lot of municipalities and waterboards this autonomous subsidence brings immense maintenance costs and discussions about sustainable land use. For the municipality of Woerden the autonomous subsidence is assessed for both rural and urban areas. For the rural areas the oxidation of peat and the consolidation due to gradually lowering of the water table are the main contributors. Using the modified “Phoenix” model the autonomous subsidence is predicted to be approximately 5 to 6 mm yr−1. In the urban areas the water table is stable and therefore the ageing of clay and creep are the driving forces for the autonomous subsidence. Using satellite data the autonomous subsidence is determined to range from 0 to 4 mm yr−1 for most parts of the city.

Abstract Background: The debate on whether caregiving is selfless or self-serving is unresolved. From the perspective of caregiving as a moral responsibility, the motivation to provide care is altruistic. The exchange or reciprocity perspective suggests that care is provided with an expectation to be cared for in the future. The context of filial obligation and rapid socio-economic transformation in recent decades in urban and rural China provided a unique opportunity to investigate these two driving forces. Methods: We tested the effects of caregiving experience in older persons on their care expectation from their children using data from the China Longitudinal Aging Social Survey (n=8,308). Using a multiple-indicator multiple-cause model, a special form of structural equation modelling, we examined the effect of caring for one’s older parents, helping adult children with housework, and caring for grandchildren on older persons’ care expectation from their children. Results: Older persons in urban areas had higher expectation for future care from their children if they have helped them with housework or took care of their grandchildren, whereas their experience of taking care of their own parents is related to a lower care expectation from their children. Although a similar pattern was observed in rural areas, only the experience of helping adult children with housework significantly increased care expectation. Discussion: Both altruistic and exchange motivations are involved in caregiving. Caring for older parents was more likely altruistic. Caring for an adult child in both urban and rural areas, and grandparenting in urban areas, were motivated by reciprocity.

Time spent on subsistence activities was compared between rural sedentes and urban migrants of the Huli population in Papua New Guinea. Person-day observation data were collected for rural sedentes (441) in the Tari basin and for urban migrants in Port Moresby (175). The time spent on subsistence activities by males was longer in the urban area than in rural areas, while that by females was similar in both areas. Conspicuous gender inequality with respect to labour hours in rural areas seems to diminish when people move to urban areas, reflecting the different subsistence regime between rural and urban environments.

According to Romania’s National Rural Development Programme, the socio-economic situation of the rural environment has a large number of weaknesses – among which low access to financial resources for small entrepreneurs and new business initiatives in rural areas and poorly developed entrepreneurial culture, characterized by a lack of basic managerial knowledge – but also a large number of opportunities – among which access of the rural population to lifelong learning and entrepreneurial skills development programmes and entrepreneurs’ access to financial instruments. The population in rural areas depends mainly on agricultural activities which give them subsistence living conditions. The gap between rural and urban areas is due to low income levels and employment rates, hence the need to obtain additional income for the population employed in subsistence and semi-subsistence farming, especially in the context of the depopulation trend. At the same time, the need to stimulate entrepreneurship in rural areas is high and is at a resonance with the need to increase the potential of rural communities from the perspective of landscape, culture, traditional activities and local resources. A solution could be to turn vegetal and / or animal farms into social farms – farms on which people with disabilities (but also adolescents and young people with anxiety, depression, self-harm, suicide, and alexithymia issues) might find a “foster” family, bed and meals in a natural, healthy environment, and share the farm’s activities with the farmer and the farmer’s family: “committing to a regular day / days and times for a mutually agreed period involves complying with any required health and safety practices (including use of protective clothing and equipment), engaging socially with the farm family members and other people working on and around the farm, and taking on tasks which would include working on the land, taking care of animals, or helping out with maintenance and other physical work”
