At present, rural areas are becoming the second largest source of greenhouse gas emissions, and it is imperative to explore a low-carbon construction and development model suitable for rural areas.In view of insufficient vitality of rural public venues, through a combination of field visits and investigations, ArcGIS spatial analysis and related mathematical statistics, the service range index and service distribution index of rural public venues are created, and Shijiaying Village, representative of the Guanzhong Plain area, is selected as an example to analyze the spatial distribution of its public venues. It is found that rural public venues present the overall characteristics of unbalanced spatial distribution, which are mainly manifested in the following aspects: first, administrative village-level public venues have small effective service range; second, there are distinctive differences in service distribution between different villages; third, rural public venues lack service in overall. Factors such as the distribution pattern of rural settlements, the location layout and type of the venues exert an important impact on the spatial distribution of rural public venues. The study is expected to provide a useful reference for the planning and construction of rural public venues and the quality improvement of human settlements in China in the new era.

Taking Jinghe River Basin in the Loess geomorphological area and Guangnan County in the karst geomorphological area as the study area, the spatial distribution characteristics of urban and rural areas of different geomorphological types are analyzed. By using GIS and related statistical analysis software, this paper summarizes three basic urban and rural types: river channel type, plateau surface type, and loess terrace horizon prototype in the Loess Landscape Jinghe River Basin. It is known that most towns in the loess plateau gully area are in the Jinghe River Basin. According to the spatial distribution characteristics of urban and rural areas, the optimal layout based on the main structure of five districts, nine River corridors, and four plates is proposed. Using the DEM module of ArcGIS to divide the elevation and gradient of Guangnan County, we know that the density of urban and rural settlements in Guangnan County is low and the spatial distribution is dispersed, and the distribution of urban and rural settlements shows a strong elevation orientation. The distribution of urban and rural settlements has a normal distribution relationship with the elevation. The largest number of urban and rural settlements is between 2.1° and 25°. According to the present situation of settlement distribution, this paper puts forward some optimization strategies, such as appropriate settlement scale, settlement space development monitoring, and so on.

Rural settlements occupy a significant part of the territory of Russia, where about 25% of the population lives and significant natural resource potential is concentrated, but the level of their socio-economic development is significantly inferior to urban ones. Increasing depressiveness of rural areas and spatial socio-economic differentiation is a systemic problem and an obstacle to the balanced development of the national economy, reduces its competitiveness due to insufficient use of economic potential, creates challenges to the economic and national security of the state. A powerful tool for countering such trends is the formation and implementation of the potential for the development of small agribusiness, which is mainly based on households created in the form of peasant (farmer) and personal subsidiary associations. The article ana-lyzes the potential of small agribusiness development in rural areas.

Development Goals

Wood-based pellets are produced in the southeastern United States (SE US) and shipped to Europe for the generation of heat and power. Effects of pellet production on selected Sustainability Development Goals (SDGs) are evaluated using industry information, available energy consumption data, and published research findings. Challenges associated with identifying relevant SDG goals and targets for this particular bioenergy supply chain and potential deleterious impacts are also discussed. We find that production of woody pellets in the SE US and shipments to displace coal for energy in Europe generate positive effects on affordable and clean energy (SDG 7), decent work and economic growth (SDG 8), industry innovation and infrastructure (SDG 9), responsible consumption and production (SDG 12), and life on land (SDG 15). Primary strengths of the pellet supply chain in the SE US are the provisioning of employment in depressed rural areas and the displacement of fossil fuels. Weaknesses are associated with potential impacts on air, water, and biodiversity that arise if the resource base and harvest activities are improperly managed. The SE US pellet supply chain provides an opportunity for transition to low-carbon industries and innovations while incentivizing better resource management.

Resilience of rural communities is becoming increasingly important to contemporary society. In this study we used a quantitative method to measure the resilience regulating ability of rural communities close to urban areas—in Licheng Subdistrict, Guangzhou City, China. The main results are as follows: (1) Rural systems close to urban areas display superior adapting and learning abilities and have a stronger overall resilience strength, the spatial distribution of which is characterized by dispersion in whole and aggregation in part; (2) the resilience of most rural economic subsystems can reach moderate or higher levels with apparent spatial agglomeration, whilst the ecological subsystem resilience and social resilience are generally weaker; the spatial distribution of the former shows a greater regional difference while the latter is in a layered layout; (3) some strategies such as rebuilding a stable ecological pattern, making use of urban resources and cultivating rural subjectivity are proposed on this basis, in order to promote the sustainable development of rural areas and realize rural revitalization. This work also gives suggestion for the creation of appropriate and effective resilience standards specifically targeted for rural community-aiming to achieve the delivery of local sustainability goals.

AIMS: This research aims to determine the epidemiology and the spatial distribution of intestinal parasitosis in the city of Teresina.METHODS: A cross-sectional study was carried out based on the data of parasitological fecal exams performed in the Laboratory Raul Bacelar between January, 2014 and July, 2017. In addition to the prevalence of intestinal parasitosis and polyparasitism, we verified the association of these diseases with gender, zone and period of the year by means of the chi-squared test, whereas the relation with age was analyzed by the Mann-Kendall tests and multiple comparisons of age classes. The spatial distribution was performed using the QGIS georeferencing software.RESULTS: The prevalence of enteroparasitosis in Teresina is 17,8% with Ascaris lumbricoides being the most common species, due to the precarious sanitary conditions of the city. The prevalence of individuals with polyparasitism is 3,13%, in which an association between the species Entamoeba coli and Entamoeba histolytica/dispar was found. There was no relation between intestinal parasitosis with gender, but we verified that individuals in rural areas are more susceptible to these diseases. The species Ascaris lumbricoides and Entamoeba histolytica/dispar occur more frequently in the first and second semester, respectively. We observed that there is an apparent tendency to increase cases of E. histolytica/dispar and reduction of cases of Giardia sp. according to aging. Mapping intestinal parasitosis showed us that there is a prevalence between one and 20% in most of Teresina's neighborhoods, and Ascariasis embodies at least 40% of cases of enteroparasitosis in these neighborhoods.CONCLUSIONS: Investments in basic sanitation and new epidemiological investigations must be carried out to control intestinal parasitosis in Teresina, emphasizing that children and the elderly should be considered priority groups in these programs.

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.

Abstract Hydropower is the second largest conventional energy resource in China. It is a renewable energy with mature technology, flexible operation, cleanliness and low carbon. A hydropower project has flood control, a water supply, navigation, irrigation and other comprehensive utilization functions. The new era in China is guided by the new energy-security strategy of ‘four revolutions and one cooperation’ and the new development concept of ‘innovation, coordination, green development, openness and sharing’. According to the dual nature of water and electricity, this paper deepens the basic understanding of hydropower from the experience of the world, the difficult problems of hydropower in China and the long-term development of hydropower enterprises. The future direction of hydropower development is explored from the following aspects: high-quality development of follow-up hydropower projects, innovative utilization of existing hydropower value, creative pursuit of hydropower-benefit growth and high-level promotion of hydropower international cooperation.

Currently, the analysis of the causes and consequences of differences in territorial systems (municipalities, regions) by individual social, demographic and economic indicators, as well as by the totality of their interaction, is becoming more and more significant and relevant. Achieving sustainable and integrated development of rural areas is an important task of state and municipal administration. In the study, the authors focus on the effectiveness of public administration in terms of meeting the needs of the population of rural areas, and describe the tools that provide a link between the basic conditions and the final result of management decisions. The basis of the analytical study was the degree of satisfaction of the population of the municipalities of the Novgorod region with the set of implemented measures in the context of the program of integrated development of rural settlements. The authors used the approach of constructing structural groupings to characterize and justify the composition of the municipalities of the Novgorod region in the directions (spheres) and the degree of actualization of needs. The article presents the results of the ranking of municipalities in the region in order to determine the most significant territories for the implementation of the measures of the integrated development program. Thus, the authors touch upon the aspect of assessing the potential of the territory to improve the effectiveness of using public administration tools.
