The government and the national electricity company (CFE) are working on supplying energy to all legally populated areas in the country through plenty of nationwide programs and international treaties. Renewable energy supplies up to 25.9% of the energy distributed all around the country (Oswald, 2017).
The panorama changes when you focus on peri-urban areas where informal settlements develop with a variety of unequal processes, conflicts and lack of urban services (Lombard, 2016). The rapid urbanization of medium size and big cities in Mexico has happened for several decades but the government programs have not satisfied the housing demand (SEDATU, 2015; Boudreau et al, 2016).
In this paper, people involved in the subject of Mexican urbanization and the path for sustainability where interview to gather the key challenges and access to sustainable energy the peri-urban areas have. News and recently published articles were also considered for this paper, given that they publish the most recent agreements and public programmes the Mexican government develop in the country to make the shift to a more sustainable future.

The objective of this paper is to elaborate species distribution models of timber species of pine in response to hazardous factors and their vulnerability in the path of sustainable management at a national scale. The localization points of 28 endemic species of Pinus were used to make the species distribution models with different climatic, topographic and soil variables in the software MaxEnt to get the potential distribution of the niche. The hazardous factors taken into account for this paper were fire events, land-use change, plagues, the incidence of 3 different climate change models; and the signs of vulnerability were classified as the state of conservation and protection of the species and the lack of forestry management in the production of timber. Based in the 28 distribution maps of the pine timber species there can be established zones for different types of interests, from conservation zone for high-risk species (Pinus mazimartinezii) to zone where it can be factual the increase or the start of sustainable timber production or forestry of new species or in new sites, like the potential of Pinus lumholtzii for timber and chemical production, that is only locally used.
The models can be used as well for the proposal of new areas for conservation of the pine diversity, as the extremely narrow distribution of Pinus jaliscana West of México, but with the possibility of migration with the climate change fluctuations South of the country. Furthermore, it can be possible to define zones with reforestation possibilities according to species characteristics that make them resistant to extreme environmental characteristics that can slow down, diminish or stop environmental, social and economic problems. All the results are fundamental for the elaboration of projects directed for sustainable management and the construction of public politics that ensure the conservation and utilization of pine timber species.
