Abstract Non-sewer sanitation systems are widely implemented for treatment and management of faecal sludge (FS) and septage in developing nations. India became an open defecation free (ODF) country in 2019, with more than 90 million toilets at rural and urban level constructed to achieve this ODF status. Government of India also initiated a faecal sludge and septage management (FSSM) policy in 2017. This paper highlights the policy vision for the state of Rajasthan and predicts options for a safely managed sanitation system through exploring the fuel potential of faecal sludge generated in the city. The intended study is an attempt to valorize faecal sludge into a marketable product through determining the heat capacity of dried faecal sludge from different sources such as pit toilets, septic tanks etc. In the present work in urban Jaipur, which is already a water scarce city, various onsite sanitation systems were targeted to collect FS samples from different locations. It was observed that the FS generated has a high heating value of 13.96 MJ/kg, with total solids ranges from 7 to 9%. For a pragmatic resource recovery option, the experimental data observed is validated with a literature review.

This paper analyses demographic trends and population decline of the rural area surrounding Niksic, Montenegro, from the second half of the 20th century to the first two decades of the 21st century. After World War II, industry in Niksic began to develop strongly. A large number of state enterprises started to operate, and the consequent industrialisation and improved living conditions triggered a wave of migration from the surrounding rural areas to Niksic. The paper describes the depopulation of rural areas and the causes and consequences of migration within the Municipality of Niksic based on an analysis of population movement and density, the rural and urban populations, and the age structure of the population. Transformations of the economy after 1990 indicate that the neglect of agriculture and the destruction of agricultural land are mistakes that will prove difficult to correct. The results of our research reveal that, today, revitalisation of the countryside is only possible if non-agricultural activities are brought to the area centres and the quality of life is improved in the villages, which would reduce unemployment in the city. A solid traffic infrastructure between individual settlements and their connection with the city is also necessary. Between 2003 and 2011, the agricultural population increased by 1.2%, which gives hope because agriculture is now being recognised as significant, and a movement for changing the inherited negative perception of it is being created. This research is addressed to the state and municipal administrations of the region with the message to implement responsible and timely measures to revitalise the countryside and stop the extinction of the villages.

Faecal Sludge

Material Flow Analysis is a method that can be used to assess sanitation systems with regard to their environmental impacts. Modelling water and nutrients flows of the urban water, wastewater and waste system can highlight risks for environmental pollution and can help evaluating the potential for linking sanitation with resource recovery and agricultural production. This study presents the results of an analysis of nitrogen and phosphorus flows of Arba Minch town in South Ethiopia. The current situation is modelled and possible scenarios for upgrading the town's sanitation system are assessed. Two different scenarios for nutrient recovery are analysed. Scenario one includes co-composting municipal organic waste with faecal sludge from pit latrines and septic tanks as well as the use of compost in agriculture. The second scenario based on urine-diversion toilets includes application of urine as fertiliser and composting of faecal matter. In order to allow for variations in the rate of adoption, the model can simulate varying degrees of technology implementation. Thus, the impact of a step-wise or successive approach can be illustrated. The results show that significant amounts of plant nutrients can be provided by both options, co-composting and urine diversion.

Destination City

In the existing research on Chinese migration, rural domestic Chinese migrants are often portrayed as a community of intruders with a detached culture who invade a host destination city. Usually, as a first step, they settle down in a so-called “Chengzhongcun” (literally a village encircled by the city boundaries, hereafter CZC), which is a kind of “urban village”, or an undeveloped part of a city that is overshadowed by the more developed areas. The present paper tries to give an image of the rural-to-urban migrants as a more vigorous mediator that forms their migration destination. The aims are the following: first, to achieve a detailed written analysis of an existing CZC community and its functioning as a mirror of the discriminating division between the rural and urban life in China. Secondly, by taking into account the experiences of migrant communities in their host cities, this paper seeks to highlight the migrants' emotional conflict and increasing loss of values that occurs in the migration process from the rural to the urban. Thirdly, the migrants' household survival strategies shall be explored. Finally, weaving these strands together, this paper presents a case study of a Tulou collective housing project in Guangzhou Province, China.

Faecal Sludge

Many sub-Saharan African towns currently face a “faecal sludge crisis”, because large amounts of faecal sludge from unsewered toilets (pit latrines, septic tanks etc.) are dumped into the environment. This causes public health problems and environmental degradation. The objective of this research was to investigate how faecal sludge management (FSM) can be made an integrated part of a sustainable ecological sanitation (ecosan) approach, with an emphasis on financial sustainability. Kumasi, a city in Ghana, West Africa, with 1.48 million inhabitants was chosen as a case study. Our research shows that the FSM of the city can be independent of donors’ financial support and thus financially sustainable if the potential revenue in both households and farmers is realised. This potential revenue was evaluated by (i) analysing the relevant functional groups and their relationships, (ii) a Capacity-to-Pay approach for households whereby they would spend up to 0.5% of their income on the toilet pit/septic tank emptying service (including a cross-subsidy approach), and (iii) on the farmers’ Willingness-To-Pay for compost (treated faecal sludge) based on a price of US$ 1.4 per 50 kg bag of compost. This additional revenue, which should be allocated to the System Manager (Kumasi Metropolitan Assembly) in the proposed financial scheme, was estimated to be US$ 57,000 per month from households and US$ 18,000 per month from farmers (based on 6300 m3/month of faecal sludge collected in Kumasi and a simplified financial analysis of the system).

The central theme of this work revolves around the foodies' movement under three perspectives: firstly, from a conceptual point of view to give account of its relevance in terms of consumer demand; secondly, to verify how, from the supply side, this movement can to some extent encourage and/or strengthen the creation of networks of local actors indispensable to encourage the meeting between the needs of the demand and supply of typical food products; thirdly, based on a case study to demonstrate that the movement of foodies can be exploited within a political action aimed at reorienting local tourism development. A national case study – Alghero, IT – was analysed. By positioning the rural and urban spaces with respect to the foodies' phenomenon, the existence/absence of networks between local stakeholders some obstacles emerged so as many opportunities. The stakeholder analysis was appliedand discussed. This method was very useful for identifying the role, power and leadership that the various local actors have in favoring or hindering the creation of connection networks between the city and the countryside, and in the requalification of the supply of typical foods that fit well into the current demand trend.

In community energy planning, a persistent disconnect has been observed between the targets and plans announced by local governments and the application of effective policy to reduce energy consumption and greenhouse gas (GHG) emissions. We use two methods to explore this implementation gap. First, we apply energy-economy modelling tools at the urban level to evaluate the effectiveness of various policy options available to local governments. Our case study for these exercises is the leading jurisdiction of Vancouver, British Columbia. Second, we report and analyze the results of a survey we administered to community energy practitioners in Canada. The modelling results point to jurisdictional reach as an important contributor to the implementation gap. We find that, while Vancouver can make significant progress by implementing policies that are clearly within its jurisdiction, the city is unlikely to meet its ambitious renewable energy and GHG emissions targets without the support of higher levels of government. The survey responses suggest that capacity limitations of local government also have a role in perpetuating the implementation gap.

The subject of this chapter is the relationship between the Tuscan cities and the families belonging to the middle ranks of the lay aristocracy, from the late tenth until the early twelfth century. Taking the case-study of Florence as a starting point, a comparison with other cities of the Tuscan March in the same period (Lucca, Pisa, Arezzo, Pistoia, and Siena) will be sketched, to see that during the eleventh century we can find a similar situation in different contexts. In fact almost everywhere the ‘mid-level’ aristocracy held extensive and dispersed landholdings, many castles and private churches in the countryside, but important urban and suburban holdings as well. They established political, social, and economic connections with the primary wielders of regional power (the marquis, the counts, the bishops and other important ecclesiastical institutions) and gravitated on the cities, taking part to urban politics and probably living there some periods during the year. The situation in Florence, however, rapidly changed during the protracted crisis of the Tuscan March at the end of the eleventh and in the early twelfth centuries, when the rural aristocracy confronted a major crisis: many lineages rapidly fragmented, the splintered branches concentrated on building compact rural lordships, and they turned their backs on Florence, without playing a role in the emerging comune. But, in the same context of the decline of the March, in other Tuscan cities the separation between rural and urban aristocracies did not take place, or at least seems to have been not so stark and dramatic. Paying attention to the strength of several factors (power of the bishops, economic attraction, connections with powerful counts families etc.), different situations will be compared to reflect about the political behaviour of rural aristocracies and their degree of integration in the urban elites during the so-called ‘consular period’.

In the middle of the 16th century many people left the Low Countries for England as a result of religious persecution and economic hardship. Several thousand of these people, mainly from the Southern Netherlands, went to Norwich, the second largest city in England. Some of them wrote letters to friends and family members whom they left behind in the Low Countries, which indicate that they valued the religious freedom and economic opportunities in Norwich. This suggests that they had a positive image of the local English people. However, if one looks at official English documents, the picture is more mixed. While some English valued the economic contribution that the migrants made, others were concerned about the effect on the local workforce, and measures were taken to restrict their economic activities. Furthermore, some people in Norwich had Catholic sympathies and this was an important motivating factor in a plot to eject the migrants from the city, which ultimately failed. In short, this article uses the situation in Norwich in the late 16th century as a case study for exploring how different sources can create contrasting images of how one group of people views another.

Peatland fires are a problem every year in Indonesia especially in Sumatera Island. In Riau during the dry season, there will be peatland fires that are difficult to extinguish. There are several reasons for peatland fires and this study will analyze whether cigarette butts can cause peat fires or not. In this research peat sample was dried at 35-45°C and at temperature at 115°C to reduce water content in peat samples. Cigarette butts as a trigger were prepared with a length of 30 mm and tested on a bomb calorimeter to determine their calorific values. The cigarette butts with the highest HHV (High Heating Value) were used and burned on the surface of the peat sample by adding airflow to the sample with varying flow rates. The fastest of smoldering combustion propagation velocity was obtained 785 mm/hour for vertical direction and 1336 mm/hour for horizontal direction with speed of airflow of 5 m/s. The highest temperature was obtained in the experiment of 902°C with the speed of airflow of 5 m/s.
