This paper aims at analysing the extent to which spatial data are accessed and shared among stakeholders. It also uses Social Network Analysis to investigate institutional and individual behaviour in that process. Finally, it investigates the level of cooperation of all involved actors towards Spatial Data Infrastructure development. Results showed that public and private organizations have been individually engaged data collection and management. However, they are still using different standards and this has led to some disparities in terms of spatial data quality. Results also revealed the existing cooperation in data sharing that follow informal relationships through friendship or goodwill. In this case, organizations that use those data for public interest get them for free, while those use them for income generation pay access fees. At the end, spatial data providers and users suggested the establishment of a spatial data sharing policy that will harmonize procedures in spatial data collection and dissemination.

Regarding energy transition in the area of mobility, the literature gives prominence to two types of actor which appear to play leading roles: public authorities and households. However, the role played by companies in this energy transition appears to have attracted only marginal attention. Nonetheless, companies influence mobility through the transport of goods, professional travel and commuter trips they generate. If they participate in the growth of this mobility, might they not also contribute to reducing it? What is the viewpoint held by companies regarding these questions? The aim of this article is to highlight the stakes of this energy transition in the domain of mobility in order to represent the viewpoint of companies. The results show that company managers are effectively concerned by the stakes of energy transition in the domain of mobility and that they have already taken measures in favour of more sustainable mobility. But this is more for economic (increased transport costs) and social (recruitment problems, turnover linked to the increased cost of car mobility) reasons than for environmental ones (reduction of greenhouse gas emissions).

Pharak region, traversed by the Everest trekking route, sees thousands of hikers come through each year to discover the Khumbu high-mountain landscapes. Formerly a region devoted to livestock farming, Pharak has experienced significant socio-economic changes since the early 1970s. The predominantly Sherpa population is gradually abandoning agro-pastoral activities in favour of greater participation in the tourism industry. By generating economic benefits, creating demand and capturing part of the labour force, tourism is engendering important transformations in the region’s agriculture. Trade is on the increase and market opportunities are reconfiguring the agrarian landscape. Market gardening, in particular, is gaining momentum and has become a new local business. This article highlights the originality of this mode of farming, which has developed in tandem with the growth of tourism but independently of the growth of cities and the construction of roads.

Pharak region, traversed by the Everest trekking route, sees thousands of hikers every year who come to discover the Khumbu high-mountain landscapes. Formerly a land of pasture, this region has been the scene of significant socio-economic changes since the early 1970s. The population, mainly Sherpa, is gradually abandoning agro-pastoral activities to become more involved in the tourism industry. By generating economic benefits, creating demand and capturing a portion of the labour force, tourism is engendering important transformations in agriculture in the region. Trade exchanges are on the increase and we are witnessing a reconfiguration of the agrarian landscape according to market opportunities. Market gardening, in particular, is gaining momentum and is the subject of a new local business. Based on this example, this article aims to highlight the originality of this way of exploiting the environment, which has developed along with the growth of tourism, yet independently of urban growth and road construction.
