A tiny, almost barren island in the Indian Ocean has become a battleground in this weekend's elections in Seychelles, prompting global environmental concern.


Assumption Island, in the western Indian Ocean, possesses little at first glance that would set even the most curious and intrepid traveller's pulse racing.


Stripped almost bare and blisteringly hot, with few man-made structures, it covers an area similar to London's Heathrow Airport and is, arguably, only slightly more scenic.


Yet this tropical island anomaly - both geographically remote and far from the popular ideal of lush paradise - has become a hotspot for geopolitical powers and eco-warriors, plus a political lightning rod in Seychelles, the country that owns it.


Situated 1,140km (700 miles) from Seychelles' most populous main island, tourist-friendly Mahé, Assumption Island is a sausage-shaped, coralline finger of low-level scrub, fringed by casuarina trees.


It was ravaged for its nitrogen-rich guano (seabird droppings) and agricultural use ended decades ago. But now, Assumption Island's strategic position and ecological value is priceless.


The island lies close to this century's Silk Road – the busy commercial shipping lanes carrying manufactured goods and materials from East Asia to Africa and beyond. India was keen to build a military base on Assumption but was rebuffed.


Permanent or de facto ownership has so far been off the cards thanks to pressure from the proud Seychellois public. As the tiny republic goes to the polls in presidential and parliamentary ballots, Assumption is a key electoral touchpoint.


At least under my watch, there will never be a foreign military base in Seychelles, President Wavel Ramkalawan tells BBC News, on the eve of polling. We are not interested in the geopolitics. We remain outside.


However, the lease of Assumption Island, or at least part of it, to the Qatari royal family has stirred sensitivities. Via a Middle East investment company, Assets Group, the Qataris are currently building an exclusive, 40-villa luxury resort there, with an upgraded concrete airstrip capable of receiving executive jets, far from prying eyes.


Assumption has one of the longest beaches in Seychelles, which is probably one of the most important green turtle nesting beaches in our country, says conservation campaigner Lucie Harter. It's a really important place to preserve.


Crucially, Assumption Island is the gateway to the Unesco-listed Aldabra atoll, home to 400 species found nowhere else on the planet.


But noisy neighbours risk disrupting nature's delicate equilibrium. Campaign groups have lodged an injunction against the government to halt the project, pending a fuller environmental impact study.


As the elections approach, Ramkalawan's government's promises on environmental protection face scrutiny, and the opposition, led by Dr Patrick Herminie, is capitalizing on these issues to challenge the incumbent.


This election may very well decide the future of not just Assumption Island, but the entire direction of Seychelles' governance and the balance between development and conservation.
