The policy responses to Covid-19 have triggered large-scale reverse migration from cities to rural areas in developing countries, exposing the vulnerability of migrants living precarious lives in cities, giving rise to debates asserting to migration as undesirable and favouring policy options to discourage the process. However, the very basis of spatial concentration and formation of cities is presence of agglomeration economies, benefits accruing to economic agents operating in cities. Presence of these agglomeration benefits in local labour markets manifests themselves in the form of an upward sloping wage curve in urban areas. We estimate the upward sloping wage curve for various size classes of cities in Indian economy and establish the presence of positive returns to occupation and industry concentration at urban locations. Controlling for worker-specific characteristics influencing wages, we establish that higher the share of an industry or an occupation in local employment as compared to national economy, the desirability of firms to pay higher wages increases. For casual labourers, occupational concentration results in higher wages. However, impact of industry concentration varies across sectors. Results supporting presence of upward sloping urban wage curve, therefore, endorse policies to correct the market failure in cities and promote migration as a desirable process.

Abstract. Observations worldwide indicate secular trends of all-sky surface solar radiation on decadal time scale, termed global dimming and brightening. Accordingly, the observed surface radiation in Japan generally shows a strong decline till the end of the 1980s and then a recovery toward around 2000. Because a substantial number of measurement stations are located within or proximate to populated areas, one may speculate that the observed trends are strongly influenced by local air pollution and are thus not of large-scale significance. This hypothesis poses a serious question as to what regional extent the global dimming and brightening are significant: Are the global dimming and brightening truly global phenomena, or regional or even only local? Our study focused on 14 meteorological observatories that measured all-sky surface solar radiation, zenith transmittance, and maximum transmittance. On the basis of municipality population time series, historical land use maps, recent satellite images, and actual site visits, we concluded that eight stations had been significantly influenced by urbanization, with the remaining six stations being left pristine. Between the urban and rural areas, no marked differences were identified in the temporal trends of the aforementioned meteorological parameters. Our finding suggests that global dimming and brightening in Japan occurred on a large scale, independently of urbanization.

The article considers the potential of Dagestan aquaculture (with trout as case study) to increase the level of social and economic development of rural areas of the republic. An economic analysis of the prospects for the development of forestry was carried out taking into account the territorial features of the Republic of Dagestan. The study shows that the socio-economic effect of the trout farming development in Dagestan can be considered as particularly significant. Its successful implementation will accelerate the solution of the following problems of the republic: - Increase of self-sufficiency of the population, fish products of own production, with fresh and high quality; - Increased consumption of fish products per capita, especially in rural areas; - Expansion of the tax base and increase of cash receipts, in the form of taxes and other payments to the budget and extrabudgetary funds at all levels; - Creation of a significant number of new jobs in rural areas and, as a result, the reduction of rural migration to urban areas; - The revival of fish processing plants; - Increased production of environmentally friendly food products in the region. The results of the study can be used in the development of the Rural Development Strategy of the region. Sustainable and large-scale development of aquaculture (fish farming) will bring the economy of the area to a higher level and make a significant contribution to improving the well-being of the rural population of the Republic of Dagestan.

Abstract. Deriving large-scale and high-quality precipitation products from satellite remote sensing spectral data is always challenging in quantitative precipitation estimation (QPE), and limited studies have been conducted even using the China’s latest Fengyun-4A (FY-4A) geostationary satellite. Taking three rainstorm events over South China as examples, a Random Forest (RF) model framework for FY-4A QPE during daytime/nighttime is established by using FY-4A multi-band spectral information, cloud parameters, high-density precipitation observations, and physical quantities from reanalysis data. During daytime (nighttime), the probability of detection of the RF model for precipitation is 0.99 (0.99), while the correlation coefficient and root-mean-square error between the retrieved and observed precipitation are 0.77 (0.82) and 1.84 (2.32) mm/h, respectively, indicating that the RF model of FY-4A QPE has high precipitation retrieval accuracy. In particular, the RF model exhibits good spatiotemporal predictive ability for precipitation intensities within the range of 0.5–10 mm/h. For the retrieved accumulated precipitation, the precipitation intensity exhibits a greater impact on the predictive ability of the QPE algorithm than the precipitation duration. Due to the higher density of automatic stations in urban areas, the accuracy of FY-4A QPE over such areas is higher compared with rural areas. Both the accumulated precipitation and the distribution density of automatic stations are more important factors for the predictive ability of the RF model of FY-4A QPE. In general, our proposed FY-4A QPE algorithm has advantages for near-real-time monitoring of summer precipitation over East Asia.

Abstract In this paper, we present a systematic analysis of large-scale human mobility patterns obtained from a passive Wi-Fi tracking system, deployed across different location typologies. We have deployed a system to cover urban areas served by public transportation systems as well as very isolated and rural areas. Over 4 years, we collected 572 million data points from a total of 82 routers covering an area of 2.8 km2. In this paper we provide a systematic analysis of the data and discuss how our low-cost approach can be used to help communities and policymakers to make decisions to improve people’s mobility at high temporal and spatial resolution by inferring presence characteristics against several sources of ground truth. Also, we present an automatic classification technique that can identify location types based on collected data.

This chapter investigates the influences of rural aging on traditional agricultural production in rural areas in Turkey concerning the traditional family as a social structure of accumulation. Traditional agricultural production in Turkey, which is generally characterized by subsistence farming, relies mostly on the unpaid family worker for survival. The influences of migration tendency of younger family members to urban areas and aging which becomes a physical challenge to remaining family members on traditional family seem to be prevalently studied and argued in the literature. As a new variable, this research focuses on the influences of a specific population, who recently returns to their rural origins from urban areas after retirement. It is found in this research that reverse migration does not only contribute to the increase of elderly population rates in rural settlements and thus rural aging; it also has direct impacts both on agricultural production and traditional family structures.

Low-carbon urbanization is the integration of urbanization and low carbonization. It is the low-carbon transformation of current urban areas, the new trend of developing model of urban and rural areas, which includes the low-carbon transition in production, living style, and ecological spaces, the low-carbon reform in economy, society, structure, and the developing model, as well as changing urban areas from high-carbon style to low-carbon style. The urbanization rate of China is almost the same with global average level, and is expected to reach 80% in 2050. Currently, urbanization replaces industrialization, becoming an important force influencing socio-economic development, climate and ecological environment changes, international relations, and political patterns. With a 2[Formula: see text]C rise in temperature, human beings have to face a series of risks brought by climate change. China’s large-scale urbanization is of great influence on others. In this context, it is necessary to take a scientific cognition of China’s urbanization process, clarifying urbanization developing pathway, turning carbon constraints into carbon bonus, avoiding high-carbon lock, and then to take opportunities in promoting economic structure under “new normal” conditions, accelerating the upgrade from urban civilization to ecological civilization, and to reach both 100-year goal and low-carbon developing goal, leading sustainable development globally.

Rural areas in China struggle with a scarcity of young farmers and the rapid aging of farming labor. Attracting and retaining university graduates in rural areas is key to achieving the goals of The Rural Revitalization Strategy of the government, which ultimately seeks to guarantee sustainable agriculture and food security in China. This study examines whether the school-to-work process in China is beneficially aligned to these goals. Survey data were collected from graduates in June 2016, and logistic models were generated to identify the probabilities of, and explore the influences on, school-to-rural outcomes. The findings reveal that most graduates who relocate to rural areas are more likely directed there from urban areas. Graduates with rural backgrounds are more likely to become rural successors than graduates with urban backgrounds. The phenomenon of children taking up the occupation of a parent is observed among those with agricultural degrees and rural backgrounds, which will facilitate the school-to-work process and improve agricultural production. In order to achieve a mix of family farms, large-scale farmlands, and educated farmers to improve food security and sustainable agriculture, the following key considerations for agricultural policy in China are proposed: provide adequate incentives, remove obstacles, and streamline the process of school-to-farming.

The study aims to develop health poverty index (HPI) using the Alkire Foster (AF) Method for Pakistan based on district representative data obtained from Pakistan Social and Living Standards Measurement (PSLM) 2012-13. Using HPI, this study investigates the spatial differences of health poverty at sub-national level and explores the socioeconomic determinants. The analysis reveals that the headcount health poverty is 41 percent in Pakistan. Further, the ratio is very high in rural areas (50 percent) as compared to urban areas (22 percent). Provincial analysis shows that Punjab is the least poor province (36 percent) while Balochistan is the poorest province (62 percent). The majority of the households are deprived in term of cost of health services, post-natal care and child immunisation. Empirical analysis shows that income, regional variation, education and awareness play very important role in explaining health poverty. To eradicate health deprivation, area and dimension specific policies are required to make efficient use of scarce resources.

Advantages And Disadvantages

The research aimed to comprehensively review the systems related to Building Integrated Photovoltaic (BIPV) and Building Integrated Wind Turbine (BIWT). The review purposed to observe the advantages and disadvantages of the application. Designers could use that comparison for consideration of choosing the most suitable Building Integrated Renewable Energy (BIRE) concept for projects. The research presented a literature review of BIRE systems, particularly on BIPV and BIWT systems. The critical analysis focused on some parameters related to their main energy source, type, influencing factor, efficiency, and boundary. The observation about BIPV would be divided into subgroups according to photovoltaic (PV) materials, modules, efficiency, performance’s boundaries, and the general rule of thumb of its installation. The research finds that the BIPV application has advantages in terms of the building’s application scale. It can be applied from small-scale to large-scale. Furthermore, the BIPV application does not need extra space and could directly replace the conventional building envelope materials. The issues of non-uniformity and heat transfer in BIPV can be solved by installing PV in folding-concept and placed an air gap with fins inside. On the other hand, BIWT also has an abundant energy source, but the application limits to windy areas (rural areas or urban areas in high elevation). Aside from those limitations, the BIWT application also has issues of structure, noise, and aesthetical value.

Human Reproduction

Between the beginning of the 1950s and the early 1970s, China, like many other countries in Asia, Africa and Latin America, experienced rapid population growth. This was due mainly to a dramatic mortality decline not offset by any decline in the birth rate. In 1970, China had a crude birth rate of 33.43 (per 1,000), a crude death rate of 7.60 (per 1,000) and a rate of natural increase of 25.83. “Population growth” was identified as a fundamental obstacle to economic development, and the stage was set for large-scale state interventions in the process of human reproduction. The apotheosis of this intervention was the introduction, in 1979, of the One Child Policy, which was successfully implemented in the urban areas. In rural areas, policies promoting later marriage, one child – maximum two – per couple, and greater spacing of those births that are permitted contributed to the swift fertility decline witnessed over the last three decades. In 1996 China's birth and death rates were reported at 16.98 per 1,000 and 6.56 per 1,000 respectively and the population was growing at 10.42 per 1,000.
