“…In addition, increased temperature, sea level, and precipitation variability are some effects brought by climate change, therefore, some places in which now A. albopictus could be present, in the future would not have adequate conditions for its permanence [124]. Nonetheless, in mountainous zones of Colombia where temperatures are currently cold and act as an ecological restriction for invading arthropods [125], variations in temperature could favor the establishment of the tiger mosquito even in altitudes above those that have been currently registered (up to 1800 m) by 2050 (up to 3100 m) and 2070 (up to 3200 m) [23,24,57].…”

In Colombia, little is known on the distribution of the Asian mosquito Aedes albopictus, main vector of dengue, chikungunya, and Zika in Asia and Oceania. Therefore, this work sought to estimate its current and future potential geographic distribution under the Representative Concentration Paths (RCP) 2.6 and 8.5 emission scenarios by 2050 and 2070, using ecological niche models. For this, predictions were made in MaxEnt, employing occurrences of A. albopictus from their native area and South America and bioclimatic variables of these places. We found that, from their invasion of Colombia to the most recent years, A. albopictus is present in 47% of the country, in peri-urban (20%), rural (23%), and urban (57%) areas between 0 and 1800 m, with Antioquia and Valle del Cauca being the departments with most of the records. Our ecological niche modelling for the currently suggests that A. albopictus is distributed in 96% of the Colombian continental surface up to 3000 m (p < 0.001) putting at risk at least 48 million of people that could be infected by the arboviruses that this species transmits. Additionally, by 2050 and 2070, under RCP 2.6 scenario, its distribution could cover to nearly 90% of continental extension up to 3100 m (≈55 million of people at risk), while under RCP 8.5 scenario, it could decrease below 60% of continental extension, but expand upward to 3200 m (< 38 million of people at risk). These results suggest that, currently in Colombia, A. albopictus is found throughout the country and climate change could diminish eventually its area of distribution, but increase its altitudinal range. In Colombia, surveillance and vector control programs must focus their attention on this vector to avoid complications in the national public health setting.

“…Colombia is hydrologically wealthy and some of the country's largest basins have a runoff that is six times greater than the world average. However, alterations in vegetation structure and sometimes in groundwater upset the water balance and make the supply of water for human consumption highly vulnerable (García et al, 2012). Disruptions to vertical water flows compromise surface runoff, meaning the amount available for consumption is diminished.…”

The effects of climate change on tropical ecosystems cannot be interpreted based on physical variables alone. Severe water shortages and deterioration of ecosystems are most acute in places where historical inequalities occur, such as unequal access to land and other goods and rights necessary for the livelihood of marginalized populations. This paper explores environmental transformations and their repercussions on water resources based on spatial analysis and fieldwork carried out in the Colombian Caribbean. We have engaged with peasant and Afro-descendant populations who have been excluded from water use and now face problems in sustaining their way of life.

“…El régimen hidrológico en la región es fuertemente afectado por la variabilidad climática vinculada con el doble paso de la Zona de Convergencia Intertropical (ZCIT); la orografía; los procesos que ocurren en los océanos Atlántico, mar Caribe, el Pacífico y la Amazonia; pero sobre todo a la influencia del fenómeno ENSO en sus fases extremas (García, Botero, Bernal, Ardila, & Piñeros, 2012;Puertas & Carvajal, 2008;Rueda & Poveda, 2006).…”
