Assessment of renewable energy resources such as surface solar radiation and wind current has great relevance in the development of local and regional energy policies. This paper examines the variability and availability of these resources as a function of possible climate changes for the Caribbean region. Global climate changes have been reported in the last decades, causing changes in the atmospheric dynamics, which affects the net solar radiation balance at the surface and the wind strength and direction. For this investigation, the future climate changes for the Caribbean are predicted using the parallel climate model (PCM) and it is coupled with the numerical model regional atmospheric modeling system (RAMS) to simulate the solar and wind energy spatial patterns changes for the specific case of the island of Puerto Rico. Numerical results from PCM indicate that the Caribbean basin from 2041 to 2055 will experience a slight decrease in the net surface solar radiation (with respect to the years 1996–2010), which is more pronounced in the western Caribbean sea. Results also indicate that the easterly winds have a tendency to increase in its magnitude, especially from the years 2070 to 2098. The regional model showed that important areas to collect solar energy are located in the eastern side of Puerto Rico, while the more intense wind speed is placed around the coast. A future climate change is expected in the Caribbean that will result in higher energy demands, but both renewable energy sources will have enough intensity to be used in the future as alternative energy resources to mitigate future climate changes.

This paper uses a case study approach to understand how perceptions of language threat have worked to maintain local language practices on the islands of Aruba and Puerto Rico. Through document analysis, interviews with key players in language policy and planning efforts as well as participant observation, this paper explains the historical build-up of the perception that Papiamento and Spanish, respectively, are in some way threatened. In addition to documenting the language maintenance efforts, the author argues that differing colonization practices impacted islanders’ orientation toward language, such that in Aruba a language-as-a-resource orientation has resulted in societal multilingualism whereas a language-as-a-problem orientation has resulted in monolingualism on the island of Puerto Rico.

Most of the knowledge of tropical storm effects on forests is from studies conducted in reserves and protected areas. Effects on other settings such as urban forests, coastal forests, and in landscapes with mixed land uses and covers are, comparatively, less studied. Yet research from a range of forest types and landscape compositions is needed to inform actions associated with management, mitigation, or restoration efforts before and after storms. Studies of forests comprising various conditions, along with long-term observations, would offer unique insights into the varied and cumulative effects of tropical storms on forest ecosystems. The Caribbean island of Puerto Rico is one of the sites where most tropical storm-forest studies are conducted, yet studies come from a limited set of sites. Using Puerto Rico as a case study, we emphasize the need for broader research approaches that represent the wider range of forests that are exposed to tropical storms. Such an approach will provide valuable knowledge and understanding needed to inform and take actions across landscape settings, forest context, and socio-environmental conditions.
