There isn't a great deal. 'Tuvalu' means 'group of eight', but there are in fact nine inhabited islands, totalling a land area of just 10 square miles, somewhere out in the South Pacific. (2500 miles North-East of Australia). This is a very small and very remote country. It is also a country in danger, as it's highest point is under 5m above sea level, so is naturally very concerned about rising sea levels.
Tuvalu became independent from the British Empire in 1978, and maintains reasonably good relations with Britain. Tuvalu, though, is not afraid to court controversy, notably being one of the few nations to regard the Republic of China, not the People's Republic, as the true government of China. Due to its vulnerable geography, Tuvalu can also be vocal on environmental issues. On TSR, this enables a rep to speak out against what it views as immoral and damaging actions of most countries in the world. Despite (or, perhaps, because of) its size and obscurity, Tuvalu stands up to West and East without fear, and can get its point across very clearly on the international stage.
Tuvalu is a poor, but industrious, nation. Many people in Tuvalu live by subsistence farming, and Tuvalu has no natural resources. (Except its domain name - .tv - which it leases out for $4 million a year!) Indeed, there are not even any sources of fresh water on the island, which became a problem during the 2011 drought, when water had to be flown in from New Zealand. Tuvalu, then, is heavily reliant on imports, which does to the tune of 60 times what it exports.
The future of Tuvalu is uncertain. A sea level rise of about 50 cm could render the country uninhabitable. Already Tuvalu has appealed to the Australian and New Zealand governments for aid in a potential evacuation of the country. Any representative for Tuvalu should work to ensure that a tiny country does not mean a tiny voice, and so get the big nations of the world to do the right thing.
