NHRE Deployment
Despite globally progressing energy transition, the deployment of non-hydropower renewable energy (NHRE) in developing countries varies by country and overall is moderate. This entry aims to explain why developing economies with significant challenges in the energy sector are not actively engaged in NHRE diffusion. In doing so, the entry reviews scholarly work on renewable energy (RE) deployment in developing countries and presents a two-stage analytical framework for assessing the NHRE development status. The procedure helps assess the current situation in the national energy sectors in connection to their economic growth and development, environmental sustainability and energy security. At the next stage, the framework lets analyse the preparedness of the national energy sectors for NHRE diffusion. The analysis spans six dimensions: structure of energy sector, RE regulation, institutions and governance, capital and investment, infrastructure and business environment, and human capital. The two-stage analytical framework assists in checking the hypothesis that more advanced economically and institutionally countries are more likely to commence NHRE development.

The Factors Impacting Commuting Time
Commuting time holds a significant role in people’s daily routines, representing the duration spent traveling between home and work in the context of daily time use. In the context of rapid urbanization in developing countries, commuting time is increasing. However, excessive commuting time can have significant economic, social, and environmental consequences. For example, longer commuting time hampers per capita income growth and reduces productivity. It also impedes social interactions among residents, leading to a decline in social and economic vitality. Moreover, commuting accounts for a large proportion of urban transportation demand and is closely linked to urban carbon emissions. Additionally, it has detrimental effects on both physical and mental health, as well as the well-being of individuals. Therefore, it is crucial to investigate the factors that influence commuting time in order to mitigate its continual increase.

Construction Differentiation Pattern of African Railway Network
Since the new century, countries in Africa have started a new round of rail network planning and construction which brings the completed different features together with the spatial organization of the railway network during the colonial period. Along with the strategic layout of “going out” with China’s railways, the organizational structure of the African railway network will make a tremendous change for the construction market, network organization, and gauge structure of the African railways.

A Development Strategy of a Low-Density Territory
Montesinho Natural Park is one of the largest Portuguese natural protected areas, presenting good biodiversity and a cultural heritage with a strong connection to the territory and its people. It constitutes a low-density territory, characterized by a human and social landscape based on community practices, such as joint aid and the community use of goods and means of agricultural production, which have contributed to the construction of the “transmontana” identity and to the richness of the habitats. The promotion of the sustainable development of this low-density rural region demands the understanding of its specificities and an appropriate approach to grasp its challenges and develop effective management tools, allowing to preserve and exploit the region’s potential from various perspectives.

The Image of the Smart City
The image of the city was first introduced by Kevin Lynch in 1960, and referred to the ways in which urban space is perceived by their users, and how these acts are based on mental maps, whose elements can be put into well-defined categories: paths, nodes, edges, districts, and landmarks.

Commuter Interdependence
The comprehensive research framework is divided into two phases, namely assessment and abatement, each of which involves a method that has been developed on the basis of an analytical framework. The vehicle emission estimation method, in the assessment phase, is built on the basis of the ‘Institution of Sustainability’ (IoS) framework to assess vehicle emission levels and identify all potential traffic-related sources influencing such emissions. Field experiments are designed, in the abatement phase, on the basis of the ‘Institutions and Development’ (IAD) framework to analyse the ‘near-to-real’ commuter interdependence, with respect to demand-based, non-technical measures in the experiment arrangement.
