In 1981~2012, the general urban wastewater in Shanghai was between 1.775~2.420 billion tons. Among the urban wastewater, the industrial wastewater emissions before 1988 was more than 1.4 billion tons, then, it was declining to about 649 million tons at 2002, a low value in the past 30 years, less than 50% of the 1980s. The percentage of industrial wastewater in the total urban wastewater discharge is falling from 76.9% in 1981 to under 30% in recent years. The living wastewater emissions increased from 424 million tons in 1981 to 1.697 billion tons in 2012. There is a relationship between the living wastewater increasing and the increase of the permanent residents in Shanghai. At the same time, the living wastewater emissions per capita per day were significantly increased from 100 kg (liter) around 1980s to around 190 kg (liter) in recent years. From 1995, the treatment and management of urban wastewater was continuing to intensify in Shanghai. The ratio of wastewater treating has increasing from 6.35% in 1995 to 85.62% of the total urban wastewater in 2012. Comparing the social-economic development and management of wastewater discharge in Shanghai, it can be seen, the wastewater emissions increasing amplitude was far less than the sizes of population growth and economic growth in the past 30 years

The ecological footprint demand and ecological capacity for the six types of productive land during 2005~2010 are calculated using the ecological footprint model in this paper by taking Dongying City as the example, and the ecological deficit of Dongying City is thereby figured out. Based on this, the indicators such as the ecological footprint of 10k yuan GDP, the ecological pressure index, the ecological diversity index, and the social economic development index, etc representing the sustainable development are calculated and analyzed, to learn that it is not allowed to be optimistic about the ecological environment in Dongying in recent years, as the ecological deficit has increased year after year, and the ecological pressure has become heavier and heavier. However, it is learned through analysis of the ecological footprint of 10k yuan GDP and the social economic development index that under the situation when the ecological pressure on economic growth in the ecological economic system of Dongying is increased, a tendency exists for the consumptive and extensive economic growth pattern to gradually step towards the ecologically intensive pattern, but it is still required to make more efforts in the aspects of reducing the ecological footprint demand and improving the ecological capacity.

This article contributes to debates over the ‘land–family bond’ in Early Modern England, in which social historians have engaged periodically during the past decade. It examines the work of Jane Whittle, Govind Sreenivasen and Alan Macfarlane and adds new archival evidence from my own study of three East Sussex villages, circa 1580–1770. Its focus is on the factors that influenced the land–family bond over time. It argues that a more nuanced understanding of individual tenant behaviour during this period cannot be reached without also charting the social, economic and demographic context in which such behaviour operated.

Migration in India has received increased scholarly attention in the past forty years, assisted by additional categories of data collected through the National Census. Considering the volume of both internal and international migration, the Indian population is relatively immobile. Most movements occur locally; 60 percent of internal migration is rural-rural on an intra-district level, consisting primarily of women moving with their husbands after marriage. Next in importance is the rural-urban migration of males seeking economic gain. The few studies done on migrants' characteristics show migration to be highly selective of age, sex, marital status, education, occupation and caste. The specific role of poverty in causing migration is still under debate. Key areas for further research include a greater focus on immobility; the social and demographic consequences of migration on sending and receiving communities; and the social, economic and demographic behavior of the migrants.

The paper aims to analyse the characteristics and trends in pastoral farming, tourism and recreation in the Norwegian and Slovenian mountains and resulting landscape changes. These land uses and related driving forces have been scrutinised in the context of economic, social, and political aspects. While pastoral farming has a centuries-old tradition in the higher altitudes of both countries, interest in mountains for tourism and recreational purposes dates back only to the nineteenth century but has been increasing steadily ever since. The findings of the study, based on a literature review and secondary data, suggest that the social, economic, and especially the political situation in Norway and Slovenia have been different, but the development of mountains in both countries in the field of mountain pasturing and tourism and recreation has shared more similarities than differences, although nuances and specificities should not be disregarded. It is evident that mountain pasturing in both countries is sensitive to societal changes. Further on, we can infer the synergy and the right balance between it and tourism and recreation can be an opportunity for a viable mountain economic situation and would preserve the long traditions of cooperation between the two sectors. //   Članek analizira značilnosti in trende pašništva in rekreacije ter posledične spremembe pokrajine v norveških in slovenskih gorah. Spremembe v rabi zemljišč in z njimi povezane gonilne sile smo preučili z ekonomskega, družbenega in političnega vidika. Planinsko pašništvo ima v obeh državah večstoletno tradicijo, zanimanje za gore iz turističnih in rekreativnih vzgibov pa se je začelo šele v 19. stoletju, vendar se od tedaj stalno povečuje. Ugotovitve te študije, ki temeljijo na pregledu obstoječe literature in sekundarnih podatkov, kažejo, da je bil družbeni, gospodarski in še posebej politični položaj na Norveškem in v Sloveniji sicer različen, vendar razvoj gorskih območij v obeh državah izkazuje več podobnosti kot razlik, pri čemur ne smemo zanemariti določenih razhajanj in posebnosti. Jasno je, da na planinsko pašništvo v obeh državah vplivajo družbene spremembe. Prav tako je očitno, da sinergija in ustrezno ravnovesje med planinskim pašništvom in turizmom ter rekreacijo nudita priložnost za vitalno gospodarsko stanje v gorah in obenem omogočata ohranitev dolgoletne tradicije sodelovanja med obema panogama.

The rapid development of arts festivals in the past quarter century should not make us forget that such festivals are a relatively new phenomenon in Europe and that their current explosion goes hand in hand with a growing differentiation in the events/festivals market (Klaić 2008). Notwithstanding the long history of major events, the social, economic and cultural phenomenon that we associate with the ‘festivalisation of culture’ is much more recent. It is also linked to a plurality of causes, such as the evolution of democratic regimes (notably in Southern Europe), or the decentralisation of power in France (Négrier and Jourda 2007).

Starting from the function of water resources to the social economic development, using the method of vector module, this thesis makes the analysis and evaluation of Enshi water resource carrying capacity. The results show that the water resource carrying capacity maintain its wide between 0.0884 to 0.1275 in 2007-2011, which shows that the carrying capacity of water resource in Enshi can meet the needs of social economic development.
