“…Therefore, the coast of Tunisia is identified by its high population concentration as it contains several different facilities including healthcare, hospitality, and civic service areas responding to the citizens' needs. This urbanization mainly relates to Greater Tunis (more than 60 km of coastline including Lake Tunis), Sfax (15 km), and Sousse (40 kms) as well as a few other important cities located on the coast such as Bizerte and Gabes, reaching a rate of 100%, 62%, 81%, 65%, and 70%, respectively [26]. There are nearly 124 km of dense urbanization associated with large and medium-sized cities along the coast, comprising a large number of universities, hospitals, parks, markets, etc.…”

Potential of Sustainable Concept for Handling Organic Waste in Tunisia

Nowadays, Tunisia is seeking to implement cost-efficient and sustainable solutions in relation to the treatment of organic waste which, at up to 65%, makes up the largest proportion of total waste generated in the country. Therefore, an efficient tool for decision makers is needed to provide a clear approach about the potential of organic waste as well as the treatment concept, which can be adapted based on technical requirements and local conditions. Results revealed that there is a high variation in terms of the nature of the collected biowaste, which affects the selection of the adopted bioprocess for each geographical zone of the study area. Three main categories of biowaste are produced along the coastline of Tunisia: food waste (FW) (102.543 t/a); green waste (GW) (1.326.930 t/a); and cattle manure (CM) (1.548.350 t/a). Based on the results of similar projects and laboratory-scale research work, anaerobic and aerobic digestion were examined. Regarding aerobic digestion, the monitoring of several physicochemical parameters ascertained that the co-composting of FW and GW at different ratios (GW: FW = 100:0, 75:25, 50:50, and 25:75) allowed the production of a stable and mature compost. A highly qualified end-product was generated from each trial categorized as a finished compost of class V with reference to German Standards of compost. Regarding the anaerobic process, different feedstock mixtures (FW:CM = 0:1, 1:1, 2:1, and 3:1) were prepared to feed semi-continuous anaerobic reactors. However, a significant improvement in the process development was recorded for digesters including a higher fraction of FW, which produced 0.846 LN/kg VSin as the maximum biogas production. Therefore, biological treatments of food waste and different co-substrates seems to be a suitable technique for Tunisia in terms of waste management, environmental, and energy aspects. However, the evaluation of the efficiency of the proposed biological treatments was also verified by a draw-up of a technical and economic feasibility analysis. Although the cost–benefit estimations proved that the profits from both the compost and biogas plants would be very modest, the feasibility of such sustainable projects should not only be evaluated on an economic basis, but also by taking into account socio-environmental considerations including decreasing environmental threats, providing work opportunities, increasing incomes, stimulating public awareness as well as reducing the operating costs linked to landfilling.

In Tunisia, and after the 2011 revolution, the electoral potential increased between 2011, 2014, 2017, 2018 and 2019. Similarly, the structure of this potential, by age and sex, has evolved during these different periods. During the 2019 presidential and legislative elections, 6,620,983 people were registered to vote within Tunisia (www.isie.tn). The structure of this electoral potential deserves to be mapped and analysed on different scales. In this study and using the Hyperatlas software, we have mapped and analyzed the Tunisian electoral potential for 2019, by sex and age group. HyperAtlas is a means of multiscale analysis. It is a "tool for measuring and mapping territorial inequalities" (Ysebaert et al., 2011). After the creation of the registration database for elections, we were able to visualize and analyse the inequalities in distribution and structures between the three regions (North, Central and South), the six sub-regions (NE, NO, CE, CO, SE and SO), the 24 governorates of the territory and the 275 delegations of the country, on the one hand, and between the different units on the other hand.

“…These two maps are very effective in the present research, insofar as they give an idea on the distribution of the population very close to reality. Maps of urban sprawl, land use changes ( Figure 3), and changes in the road network are also extracted from previous studies (Mandeli, 2008;Al Sulami, 2010;Baesse, 2012;Belarem et al, 2016, Al-Enazi, 2016aAljoufie et al, 2013aAljoufie et al, , 2013bAljoufie et al, , 2013cAljoufie et al, , 2014aAljoufie et al, , 2014bAljoufie et al, , 2016aAljoufie et al, , 2016bChouari & Belarem, 2017;Ajmi et al, 2014).…”

The study of the localization of girls' secondary schools in Jeddah shows that the school map is both a diagnostic and perspective tool for school policies. It is also a tool for research, for measuring accessibility and thus for helping decision-makers in the education sector (Ministry of education, regional education directorates, etc.) insofar as it makes it possible to visualize the scenarios of educational facilities. Through the present study, we have developed a map showing the distribution of the girls' secondary schools in Jeddah. This map shows for some households a low accessibility to these schools. That has enabled us to propose facilities to reassure a certain equality of opportunity for access to secondary schools.
