By Lilian Yamamoto, Miguel Esteban

Atoll Island States exist on most sensible of what's gave the impression to be one of many planet's so much weak ecosystems: atolls. it's been anticipated that a rise within the speed of sea point upward push led to through expanding greenhouse fuel concentrations within the surroundings will lead them to disappear, forcing their population emigrate.
The current ebook represents a multidisciplinary criminal and engineering point of view in this challenge, hard a few universal misconceptions relating to atolls and their vulnerability to sea-level upward push. Coral islands have survived previous alterations in sea degrees, and it's the survival of coral reefs what's going to be an important for his or her endured life. those islands are vital for his or her population as they symbolize not just their ancestral agricultural lands and historical past, but in addition a income during the exploitation of the maritime components linked to them. notwithstanding, whether confronted with severe weather switch, it will probably theoretically be attainable for the richer Atoll Island States to engineer how one can hinder their major islands from disappearing, although unfortunately no longer all can have the necessary monetary assets to take action.
As islands turn into gradually uninhabitable their citizens might be compelled to settle in overseas lands, and will turn into stateless if the Atoll Island country ceases to be well-known as a sovereign state. in spite of the fact that, instead of tackling this challenge by means of getting into long negotiations over new treaties, simpler options, encompassing bilateral negotiations or the opportunity of buying small new territories, may be explored. this could be sure that Atoll Island States sooner or later to maintain a few type of overseas sovereign character, which may profit the descendents of its cutting-edge inhabitants.

The effects of climate change on coral reefs will be described in more detail in Chap. 3. 2 Foraminifers Foraminifers are single-cell amoeboid protists that typically produce a small shell made of calcium carbonate or agglutinated sediment particles. Usually they are less than 1 mm in size, though they can grow up to 20 cm long (Fig. 12). They move and catch their food with a network of thin extensions of the cytoplasm. Their food consists on a variety of other creatures such as diatoms, algae or other foraminifera, and some shallow water species have symbiotic algae to perform photosynthesis.

75 Magnan et al. (2011). 74 References 33 longshore drift). The construction of jetties or dredging traps sediments, leads to erosion elsewhere in the coastline, a well known problem in coastal engineering. Socio-economically speaking, Atoll Island States tend to be medium to low income countries, with their economy dependent on agriculture, fishing, tourism, the revenue originating from their Exclusive Economic Zones (EEZ) and overseas aid. They typically have high population densities, often concentrated on the island where the capital is located, where most of the important infrastructure and government institutions are also situated.

180–213. 2 Factors affecting morphological changes in Atolls (adapted from Sato and Yokoki 2010, p. 54 The study found changes in the shapes of the island in the atoll, but concluded that it was likely that much of the present lagoon shoreline instability was the effect of profound changes due to dredging by the US military during the 1940s. 57 It is thus important to remain objective about the real reasons behind coastal erosion in littoral areas, as this is a well documented phenomenon typically linked to human activities rather than to climate change.
