“…In addition, there are nutrient pulses during seasonal upwelling, strong turbulent vertical mixing and entrainment of subsurface water into the surface layer driven by mountain gap-winds [ 3 ]. Low and variable pH values have also been reported in recent studies [ 4 – 8 ]. The synergy between harsh environmental conditions and low accommodation space has restricted the production of skeletal calcium carbonate, resulting in small, patchy reefs prone to erosion [ 9 ].…”

There are many marine protected areas (MPAs) containing coral reef aggregations in the eastern Pacific region. However, the connectivity of corals between MPAs is still poorly known, especially in the Marine Conservation Corridor of the Eastern Tropical Pacific (MCCETP). Here, we assess the potential connectivity of corals across equatorial eastern Pacific MPAs through a Lagrangian particle-tracking algorithm coupled offline with an ocean-circulation numerical model. Connectivity metrics and graph theory were used to analyze the networks and highlight those MPAs that are critical for maintaining the connectivity of corals across the region. Our results show that the equatorial eastern Pacific MPAs form a relatively well-connected network, at least 40% of coral larvae released per year end up within the boundaries of an MPA. MPAs like Malpelo and Gorgona islands included in the MCCETP were found to be critical for connectivity of corals because of their high betweenness centrality and potential role as stepping-stones between coastal MPAs and offshore MPAs such as the Galapagos Islands. Two pelagic larval duration (PLD) scenarios (40 and 130 days) indicate a quasi-unidirectional larval flow from coastal MPAs toward oceanic MPAs, where the only resilient MPAs (Coiba and Malpelo islands) depend mostly on subsidiary recruitment from MPAs located along the coast of Costa Rica, Panama and Colombia. In the two PLD scenarios, Cocos Island maintains a very low resilience potential. Our results indicate the imperative need to include coastal MPAs in the MCCETP network initiative, since connectivity and resilience of coral reefs in the equatorial eastern Pacific region rely heavily on coastal MPAs.

“…Finalmente, dado que en la actualidad las especies de Pocillopora en el POT se desarrollan en condiciones ambientales no óptimas (Kleypas et al, 1999), es posible que la elevación de temperatura se traduzca en la aparición de condiciones más adecuadas para su desarrollo en el futuro. Estos resultados sugieren que a escala regional es posible que la elevación de la temperatura favorezca el desarrollo de los arrecifes de coral, pero que debido a la fragilidad de sus esqueletos, al menos el servicio ambiental de protección costera no sea tan eficiente como en la actualidad (Guinotte et al, 2003;Manzello et al, 2017). En el contexto de la conservación de estos ecosistemas, la identificación de zonas que podrían ser favorables para la presencia de arrecifes a futuro, podría ser útil para considerarlas para la implementación de nuevas áreas marinas protegidas, como la costa occidental de la península de Baja California.…”

“…Firstly, while sea-level rise does cause erosion and more frequent, and intense flooding events (Nurse et al 2014), and floods can damage property, destroy crops, contaminate water supplies and spread disease through penetrating septic tanks (ADB 2014), it is not the only climate hazard driving mobility. Changes in rainfall can combine with lack of aquifers to produce a shortage of water for bathing, drinking, cooking and agriculture (IPCC 2014) and the increase in CO 2 in the atmosphere is contributing to ocean acidification, impacting on fisheries (Manzello et al 2017). Secondly, islanders are not automatons which respond to climate change in fixed way by moving away from the sea.…”

Loss and Damage From Climate Change

How do we understand displacement and resettlement in the context of climate change? This chapter outlines challenges and debates in the literature connecting climate change to the growing global flow of people. We begin with an outline of the literature on environmental migration, specifically the definitions, measurements, and forms of environmental migration. The discussion then moves to challenges in the reception of migrants, treating the current scholarship on migrant resettlement. We detail a selection of cases in which the environment plays a role in the displacement of a population, including sea level rise in Pacific Island States, cyclonic storms in Bangladesh, and desertification in West Africa, as well as the role of deforestation in South America's Southern Cone as a driver of both climate change and migration. We outline examples of each, highlighting the complex set of losses and damages incurred by populations in each case.
